+ +## Filters + +EJS conditionally supports the concept of "filters".

<%=: users | map:'name' | join %>

+ +Output: + +

Tj, Mape, Guillermo

+ +Render call: + + ejs.render(str, { + users: [ + { name: 'tj' }, + { name: 'mape' }, + { name: 'guillermo' } + ] + }); + +Or perhaps capitalize the first user's name for display: + +

<%=: users | first | capitalize %>

+ +## Filter list + +Currently these filters are available: + + - first + - last + - capitalize + - downcase + - upcase + - sort + - sort_by:'prop' + - size + - length + - plus:n + - minus:n + - times:n + - divided_by:n + - join:'val' + - truncate:n + - truncate_words:n + - replace:pattern,substitution + - prepend:val + - append:val + - map:'prop' + - reverse + - get:'prop' + +## Adding filters + + To add a filter simply add a method to the `.filters` object: + +```js +ejs.filters.last = function(obj) { + return obj[obj.length - 1]; +}; +``` + +## Layouts + + Currently EJS has no notion of blocks, only compile-time `include`s, + however you may still utilize this feature to implement "layouts" by + simply including a header and footer like so: + +```html +<% include head %> +

    <%= user.name %>

    \n <% } %>\n \n## Try out a live example now\n\n\n\n## Usage\n\n ejs.compile(str, options);\n // => Function\n\n ejs.render(str, options);\n // => str\n\n## Options\n\n - `cache` Compiled functions are cached, requires `filename`\n - `filename` Used by `cache` to key caches\n - `scope` Function execution context\n - `debug` Output generated function body\n - `compileDebug` When `false` no debug instrumentation is compiled\n - `client` Returns standalone compiled function\n - `open` Open tag, defaulting to \"<%\"\n - `close` Closing tag, defaulting to \"%>\"\n - * All others are template-local variables\n\n## Includes\n\n Includes are relative to the template with the `include` statement,\n for example if you have \"./views/users.ejs\" and \"./views/user/show.ejs\"\n you would use `<% include user/show %>`. The included file(s) are literally\n included into the template, _no_ IO is performed after compilation, thus\n local variables are available to these included templates.\n\n```\n
      \n <% users.forEach(function(user){ %>\n <% include user/show %>\n <% }) %>\n
    \n```\n\n## Custom delimiters\n\nCustom delimiters can also be applied globally:\n\n var ejs = require('ejs');\n ejs.open = '{{';\n ejs.close = '}}';\n\nWhich would make the following a valid template:\n\n

    {{= title }}

    \n\n## Filters\n\nEJS conditionally supports the concept of \"filters\". A \"filter chain\"\nis a designer friendly api for manipulating data, without writing JavaScript.\n\nFilters can be applied by supplying the _:_ modifier, so for example if we wish to take the array `[{ name: 'tj' }, { name: 'mape' }, { name: 'guillermo' }]` and output a list of names we can do this simply with filters:\n\nTemplate:\n\n

    <%=: users | map:'name' | join %>

    \n\nOutput:\n\n

    Tj, Mape, Guillermo

    \n\nRender call:\n\n ejs.render(str, {\n users: [\n { name: 'tj' },\n { name: 'mape' },\n { name: 'guillermo' }\n ]\n });\n\nOr perhaps capitalize the first user's name for display:\n\n

    <%=: users | first | capitalize %>

    \n\n## Filter list\n\nCurrently these filters are available:\n\n - first\n - last\n - capitalize\n - downcase\n - upcase\n - sort\n - sort_by:'prop'\n - size\n - length\n - plus:n\n - minus:n\n - times:n\n - divided_by:n\n - join:'val'\n - truncate:n\n - truncate_words:n\n - replace:pattern,substitution\n - prepend:val\n - append:val\n - map:'prop'\n - reverse\n - get:'prop'\n\n## Adding filters\n\n To add a filter simply add a method to the `.filters` object:\n \n```js\nejs.filters.last = function(obj) {\n return obj[obj.length - 1];\n};\n```\n\n## Layouts\n\n Currently EJS has no notion of blocks, only compile-time `include`s,\n however you may still utilize this feature to implement \"layouts\" by\n simply including a header and footer like so:\n\n```html\n<% include head %>\n

    Title

    \n

    My page

If this value is exceeded, an `error` event is emitted. + The default size is 2MB. + * `maxFields` - Limits the number of fields that will be parsed before + emitting an `error` event. A file counts as a field in this case. + Defaults to 1000. + * `autoFields` - Enables `field` events. This is automatically set to `true` + if you add a `field` listener. + * `autoFiles` - Enables `file` events. This is automatically set to `true` + if you add a `file` listener. + * `uploadDir` - Only relevant when `autoFiles` is `true`. The directory for + placing file uploads in. You can move them later using `fs.rename()`. + Defaults to `os.tmpDir()`. + * `hash` - Only relevant when `autoFiles` is `true`. If you want checksums + calculated for incoming files, set this to either `sha1` or `md5`. + Defaults to off. + +#### form.parse(request, [cb]) + +Parses an incoming node.js `request` containing form data.

However sometimes, as in the case of a +`` the multipart stream will contain +multiple files of the same input name, and you are interested in all of them. +In this case, use `filesList`. + +Another example is when you do not care what the field name of a file is; you +are merely interested in a single upload.

You could use this, for + example, to set the `Content-Length` header if uploading to S3. + If the part had a `Content-Length` header then that value is used + here instead. + +#### 'aborted' + +Emitted when the request is aborted.

(That would +// be a valid example of a transform, of course.) +// +// While the output is causally related to the input, it's not a +// necessarily symmetric or synchronous transformation. For example, +// a zlib stream might take multiple plain-text writes(), and then +// emit a single compressed chunk some time in the future. +// +// Here's how this works: +// +// The Transform stream has all the aspects of the readable and writable +// stream classes. When you write(chunk), that calls _write(chunk,cb) +// internally, and returns false if there's a lot of pending writes +// buffered up. When you call read(), that calls _read(n) until +// there's enough pending readable data buffered up. +// +// In a transform stream, the written data is placed in a buffer. When +// _read(n) is called, it transforms the queued up data, calling the +// buffered _write cb's as it consumes chunks. If consuming a single +// written chunk would result in multiple output chunks, then the first +// outputted bit calls the readcb, and subsequent chunks just go into +// the read buffer, and will cause it to emit 'readable' if necessary. +// +// This way, back-pressure is actually determined by the reading side, +// since _read has to be called to start processing a new chunk. However, +// a pathological inflate type of transform can cause excessive buffering +// here. For example, imagine a stream where every byte of input is +// interpreted as an integer from 0-255, and then results in that many +// bytes of output. Writing the 4 bytes {ff,ff,ff,ff} would result in +// 1kb of data being output. In this case, you could write a very small +// amount of input, and end up with a very large amount of output. In +// such a pathological inflating mechanism, there'd be no way to tell +// the system to stop doing the transform. A single 4MB write could +// cause the system to run out of memory. +// +// However, even in such a pathological case, only a single written chunk +// would be consumed, and then the rest would wait (un-transformed) until +// the results of the previous transformed chunk were consumed. + +module.exports = Transform; + +var Duplex = require('./_stream_duplex'); +var util = require('util'); +if (!util.isUndefined) { + var utilIs = require('core-util-is'); + for (var f in utilIs) { + util[f] = utilIs[f]; + } +} +util.inherits(Transform, Duplex); + + +function TransformState(options, stream) { + this.afterTransform = function(er, data) { + return afterTransform(stream, er, data); + }; + + this.needTransform = false; + this.transforming = false; + this.writecb = null; + this.writechunk = null; +} + +function afterTransform(stream, er, data) { + var ts = stream._transformState; + ts.transforming = false; + + var cb = ts.writecb; + + if (!cb) + return stream.emit('error', new Error('no writecb in Transform class')); + + ts.writechunk = null; + ts.writecb = null; + + if (!util.isNullOrUndefined(data)) + stream.push(data); + + if (cb) + cb(er); + + var rs = stream._readableState; + rs.reading = false; + if (rs.needReadable || rs.length < rs.highWaterMark) { + stream._read(rs.highWaterMark); + } +} + + +function Transform(options) { + if (!(this instanceof Transform)) + return new Transform(options); + + Duplex.call(this, options); + + this._transformState = new TransformState(options, this); + + // when the writable side finishes, then flush out anything remaining. + var stream = this; + + // start out asking for a readable event once data is transformed. + this._readableState.needReadable = true; + + // we have implemented the _read method, and done the other things + // that Readable wants before the first _read call, so unset the + // sync guard flag. + this._readableState.sync = false; + + this.once('prefinish', function() { + if (util.isFunction(this._flush)) + this._flush(function(er) { + done(stream, er); + }); + else + done(stream); + }); +} + +Transform.prototype.push = function(chunk, encoding) { + this._transformState.needTransform = false; + return Duplex.prototype.push.call(this, chunk, encoding); +}; + +// This is the part where you do stuff! +// override this function in implementation classes. +// 'chunk' is an input chunk. +// +// Call `push(newChunk)` to pass along transformed output +// to the readable side.

This code is simpler, has all deprecated functionality removed,\n has cleaner tests, and does not try to do anything beyond multipart stream\n parsing.\n\n## Installation\n\n```\nnpm install multiparty\n```\n\n## Usage\n\n * See [examples](examples).\n\nParse an incoming `multipart/form-data` request.\n\n```js\nvar multiparty = require('multiparty')\n , http = require('http')\n , util = require('util')\n\nhttp.createServer(function(req, res) {\n if (req.url === '/upload' && req.method === 'POST') {\n // parse a file upload\n var form = new multiparty.Form();\n\n form.parse(req, function(err, fields, files) {\n res.writeHead(200, {'content-type': 'text/plain'});\n res.write('received upload:\\n\\n');\n res.end(util.inspect({fields: fields, files: files}));\n });\n\n return;\n }\n\n // show a file upload form\n res.writeHead(200, {'content-type': 'text/html'});\n res.end(\n '
    '+\n '
    '+\n '
    '+\n ''+\n '
    '\n );\n}).listen(8080);\n```\n\n## API\n\n### multiparty.Form\n```js\nvar form = new multiparty.Form(options)\n```\nCreates a new form. Options:\n\n * `encoding` - sets encoding for the incoming form fields. Defaults to `utf8`.\n * `maxFieldSize` - Limits the amount of memory a field (not a file) can\n allocate in bytes. If this value is exceeded, an `error` event is emitted.\n The default size is 2MB.\n * `maxFields` - Limits the number of fields that will be parsed before\n emitting an `error` event. A file counts as a field in this case.\n Defaults to 1000.\n * `autoFields` - Enables `field` events. This is automatically set to `true`\n if you add a `field` listener.\n * `autoFiles` - Enables `file` events. This is automatically set to `true`\n if you add a `file` listener.\n * `uploadDir` - Only relevant when `autoFiles` is `true`. The directory for\n placing file uploads in. You can move them later using `fs.rename()`.\n Defaults to `os.tmpDir()`.\n * `hash` - Only relevant when `autoFiles` is `true`. If you want checksums\n calculated for incoming files, set this to either `sha1` or `md5`.\n Defaults to off.\n\n#### form.parse(request, [cb])\n\nParses an incoming node.js `request` containing form data. If `cb` is\nprovided, `autoFields` and `autoFiles` are set to `true` and all fields and\nfiles are collected and passed to the callback:\n\n```js\nform.parse(req, function(err, fieldsObject, filesObject, fieldsList, filesList) {\n // ...\n});\n```\n\nIt is often convenient to access a field or file by name. In this situation,\nuse `fieldsObject` or `filesObject`. However sometimes, as in the case of a\n`` the multipart stream will contain\nmultiple files of the same input name, and you are interested in all of them.\nIn this case, use `filesList`.\n\nAnother example is when you do not care what the field name of a file is; you\nare merely interested in a single upload. In this case, set `maxFields` to 1\n(assuming no other fields expected besides the file) and use `filesList[0]`.\n\n#### form.bytesReceived\n\nThe amount of bytes received for this form so far.\n\n#### form.bytesExpected\n\nThe expected number of bytes in this form.\n\n### Events\n\n#### 'error' (err)\n\nYou definitely want to handle this event. If not your server *will* crash when\nusers submit bogus multipart requests!\n\n#### 'part' (part)\n\nEmitted when a part is encountered in the request. `part` is a\n`ReadableStream`. It also has the following properties:\n\n * `headers` - the headers for this part. For example, you may be interested\n in `content-type`.\n * `name` - the field name for this part\n * `filename` - only if the part is an incoming file\n * `byteOffset` - the byte offset of this part in the request body\n * `byteCount` - assuming that this is the last part in the request,\n this is the size of this part in bytes. You could use this, for\n example, to set the `Content-Length` header if uploading to S3.\n If the part had a `Content-Length` header then that value is used\n here instead.\n\n#### 'aborted'\n\nEmitted when the request is aborted. This event will be followed shortly\nby an `error` event. In practice you do not need to handle this event.\n\n#### 'progress' (bytesReceived, bytesExpected)\n\n#### 'close'\n\nEmitted after all parts have been parsed and emitted. Not emitted if an `error`\nevent is emitted. This is typically when you would send your response.\n\n#### 'file' (name, file)\n\n**By default multiparty will not touch your hard drive.** But if you add this\nlistener, multiparty automatically sets `form.autoFiles` to `true` and will\nstream uploads to disk for you. \n\n * `name` - the field name for this file\n * `file` - an object with these properties:\n - `fieldName` - same as `name` - the field name for this file\n - `originalFilename` - the filename that the user reports for the file\n - `path` - the absolute path of the uploaded file on disk\n - `headers` - the HTTP headers that were sent along with this file\n - `size` - size of the file in bytes\n\nIf you set the `form.hash` option, then `file` will also contain a `hash`\nproperty which is the checksum of the file.\n\n#### 'field' (name, value)\n\n * `name` - field name\n * `value` - string field value\n\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/superjoe30/node-multiparty/issues" + }, + "_id": "multiparty@2.2.0", + "dist": { + "shasum": "6f771955f8cffe3d08937a9592db04e1573bfb34" + }, + "_from": "multiparty@2.2.0", + "_resolved": "https://registry.npmjs.org/multiparty/-/multiparty-2.2.0.tgz" +} diff --git a/node_modules/express/node_modules/connect/node_modules/multiparty/test/bench-multipart-parser.js b/node_modules/express/node_modules/connect/node_modules/multiparty/test/bench-multipart-parser.js new file mode 100644 index 0000000..ee5dbad --- /dev/null +++ b/node_modules/express/node_modules/connect/node_modules/multiparty/test/bench-multipart-parser.js @@ -0,0 +1,76 @@ +var assert = require('assert') + , Form = require('../').Form + , boundary = '-----------------------------168072824752491622650073' + , mb = 100 + , buffer = createMultipartBuffer(boundary, mb * 1024 * 1024) + +var callbacks = { + partBegin: -1, + partEnd: -1, + headerField: -1, + headerValue: -1, + partData: -1, + end: -1, +};

E.g.\n\n mime.extension('text/x-some-format'); // => 'x-sf'\n\n### mime.load(filepath)\n\nLoad mappings from an Apache \".types\" format file\n\n mime.load('./my_project.types');\n\nThe .types file format is simple - See the `types` dir for examples.\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/broofa/node-mime/issues" + }, + "_id": "mime@1.2.11", + "_from": "mime@~1.2.9" +} diff --git a/node_modules/express/node_modules/send/node_modules/mime/test.js b/node_modules/express/node_modules/send/node_modules/mime/test.js new file mode 100644 index 0000000..2cda1c7 --- /dev/null +++ b/node_modules/express/node_modules/send/node_modules/mime/test.js @@ -0,0 +1,84 @@ +/** + * Usage: node test.js + */ + +var mime = require('./mime'); +var assert = require('assert'); +var path = require('path'); + +function eq(a, b) { + console.log('Test: ' + a + ' === ' + b); + assert.strictEqual.apply(null, arguments); +} + +console.log(Object.keys(mime.extensions).length + ' types'); +console.log(Object.keys(mime.types).length + ' extensions\n'); + +// +// Test mime lookups +// + +eq('text/plain', mime.lookup('text.txt')); // normal file +eq('text/plain', mime.lookup('TEXT.TXT')); // uppercase +eq('text/plain', mime.lookup('dir/text.txt')); // dir + file +eq('text/plain', mime.lookup('.text.txt')); // hidden file +eq('text/plain', mime.lookup('.txt')); // nameless +eq('text/plain', mime.lookup('txt')); // extension-only +eq('text/plain', mime.lookup('/txt')); // extension-less () +eq('text/plain', mime.lookup('\\txt')); // Windows, extension-less +eq('application/octet-stream', mime.lookup('text.nope')); // unrecognized +eq('fallback', mime.lookup('text.fallback', 'fallback')); // alternate default + +// +// Test extensions +// + +eq('txt', mime.extension(mime.types.text)); +eq('html', mime.extension(mime.types.htm)); +eq('bin', mime.extension('application/octet-stream')); +eq('bin', mime.extension('application/octet-stream ')); +eq('html', mime.extension(' text/html; charset=UTF-8')); +eq('html', mime.extension('text/html; charset=UTF-8 ')); +eq('html', mime.extension('text/html; charset=UTF-8')); +eq('html', mime.extension('text/html ; charset=UTF-8')); +eq('html', mime.extension('text/html;charset=UTF-8')); +eq('html', mime.extension('text/Html;charset=UTF-8')); +eq(undefined, mime.extension('unrecognized')); + +// +// Test node.types lookups +// + +eq('application/font-woff', mime.lookup('file.woff')); +eq('application/octet-stream', mime.lookup('file.buffer')); +eq('audio/mp4', mime.lookup('file.m4a')); +eq('font/opentype', mime.lookup('file.otf')); + +// +// Test charsets +// + +eq('UTF-8', mime.charsets.lookup('text/plain')); +eq(undefined, mime.charsets.lookup(mime.types.js)); +eq('fallback', mime.charsets.lookup('application/octet-stream', 'fallback')); + +// +// Test for overlaps between mime.types and node.types +// + +var apacheTypes = new mime.Mime(), nodeTypes = new mime.Mime(); +apacheTypes.load(path.join(__dirname, 'types/mime.types')); +nodeTypes.load(path.join(__dirname, 'types/node.types')); + +var keys = [].concat(Object.keys(apacheTypes.types)) + .concat(Object.keys(nodeTypes.types)); +keys.sort(); +for (var i = 1; i < keys.length; i++) { + if (keys[i] == keys[i-1]) { + console.warn('Warning: ' + + 'node.types defines ' + keys[i] + '->' + nodeTypes.types[keys[i]] + + ', mime.types defines ' + keys[i] + '->' + apacheTypes.types[keys[i]]); + } +} + +console.log('\nOK'); diff --git a/node_modules/express/node_modules/send/node_modules/mime/types/mime.types b/node_modules/express/node_modules/send/node_modules/mime/types/mime.types new file mode 100644 index 0000000..da8cd69 --- /dev/null +++ b/node_modules/express/node_modules/send/node_modules/mime/types/mime.types @@ -0,0 +1,1588 @@ +# This file maps Internet media types to unique file extension(s). +# Although created for httpd, this file is used by many software systems +# and has been placed in the public domain for unlimited redisribution. +# +# The table below contains both registered and (common) unregistered types. +# A type that has no unique extension can be ignored -- they are listed +# here to guide configurations toward known types and to make it easier to +# identify "new" types.

Aliased as `.from(dir)`.\n\n### .index(path)\n\n By default send supports \"index.html\" files, to disable this\n invoke `.index(false)` or to supply a new index pass a string.\n\n### .maxage(ms)\n\n Provide a max-age in milliseconds for http caching, defaults to 0.\n\n### .hidden(bool)\n\n Enable or disable transfer of hidden files, defaults to false.\n\n## Error-handling\n\n By default when no `error` listeners are present an automatic response will be made, otherwise you have full control over the response, aka you may show a 5xx page etc.\n\n## Caching\n\n It does _not_ perform internal caching, you should use a reverse proxy cache such\n as Varnish for this, or those fancy things called CDNs. If your application is small enough that it would benefit from single-node memory caching, it's small enough that it does not need caching at all ;).\n\n## Debugging\n\n To enable `debug()` instrumentation output export __DEBUG__:\n\n```\n$ DEBUG=send node app\n```\n\n## Running tests\n\n```\n$ npm install\n$ make test\n```\n\n## License \n\n(The MIT License)\n\nCopyright (c) 2012 TJ

[node](http://nodejs.org).\n\n [![Build Status](https://secure.travis-ci.org/visionmedia/express.png)](http://travis-ci.org/visionmedia/express) [![Gittip](http://img.shields.io/gittip/visionmedia.png)](https://www.gittip.com/visionmedia/)\n\n```js\nvar express = require('express');\nvar app = express();\n\napp.get('/', function(req, res){\n res.send('Hello World');\n});\n\napp.listen(3000);\n```\n\n## Installation\n\n $ npm install -g express\n\n## Quick Start\n\n The quickest way to get started with express is to utilize the executable `express(1)` to generate an application as shown below:\n\n Create the app:\n\n $ npm install -g express\n $ express /tmp/foo && cd /tmp/foo\n\n Install dependencies:\n\n $ npm install\n\n Start the server:\n\n $ node app\n\n## Features\n\n * Built on [Connect](http://github.com/senchalabs/connect)\n * Robust routing\n * HTTP helpers (redirection, caching, etc)\n * View system supporting 14+ template engines\n * Content negotiation\n * Focus on high performance\n * Environment based configuration\n * Executable for generating applications quickly\n * High test coverage\n\n## Philosophy\n\n The Express philosophy is to provide small, robust tooling for HTTP servers, making\n it a great solution for single page applications, web sites, hybrids, or public\n HTTP APIs.\n\n Built on Connect, you can use _only_ what you need, and nothing more. Applications\n can be as big or as small as you like, even a single file. Express does\n not force you to use any specific ORM or template engine. With support for over\n 14 template engines via [Consolidate.js](http://github.com/visionmedia/consolidate.js),\n you can quickly craft your perfect framework.\n\n## More Information\n\n * [Website and Documentation](http://expressjs.com/) stored at [visionmedia/expressjs.com](https://github.com/visionmedia/expressjs.com)\n * Join #express on freenode\n * [Google Group](http://groups.google.com/group/express-js) for discussion\n * Follow [tjholowaychuk](http://twitter.com/tjholowaychuk) on twitter for updates\n * Visit the [Wiki](http://github.com/visionmedia/express/wiki)\n * [Русскоязычная документация](http://jsman.ru/express/)\n * Run express examples [online](https://runnable.com/express)\n\n## Viewing Examples\n\nClone the Express repo, then install the dev dependencies to install all the example / test suite dependencies:\n\n $ git clone git://github.com/visionmedia/express.git --depth 1\n $ cd express\n $ npm install\n\nThen run whichever tests you want:\n\n $ node examples/content-negotiation\n\nYou can also view live examples here:\n\n\n\n## Running Tests\n\nTo run the test suite, first invoke the following command within the repo, installing the development dependencies:\n\n $ npm install\n\nThen run the tests:\n\n $ make test\n\n## Contributors\n\n https://github.com/visionmedia/express/graphs/contributors\n\n## License\n\n(The MIT License)\n\nCopyright (c) 2009-2012 TJ Holowaychuk <tj@vision-media.ca>\n\nPermission is hereby granted, free of charge, to any person obtaining\na copy of this software and associated documentation files (the\n'Software'), to deal in the Software without restriction, including\nwithout limitation the rights to use, copy, modify, merge, publish,\ndistribute, sublicense, and/or sell copies of the Software, and to\npermit persons to whom the Software is furnished to do so, subject to\nthe following conditions:\n\nThe above copyright notice and this permission notice shall be\nincluded in all copies or substantial portions of the Software.\n\nTHE SOFTWARE IS PROVIDED 'AS IS', WITHOUT WARRANTY OF ANY KIND,\nEXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF\nMERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.\nIN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY\nCLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT,\nTORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE\nSOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.\n", + "readmeFilename": "Readme.md", + "bugs": { + "url": "https://github.com/visionmedia/express/issues" + }, + "_id": "express@3.4.8", + "dist": { + "shasum": "aa7a8986de07053337f4bc5ed9a6453d9cc8e2e1" + }, + "_from": "express@3.4.8", + "_resolved": "https://registry.npmjs.org/express/-/express-3.4.8.tgz" +} diff --git a/node_modules/less-middleware/.npmignore b/node_modules/less-middleware/.npmignore new file mode 100644 index 0000000..2ccbe46 --- /dev/null +++ b/node_modules/less-middleware/.npmignore @@ -0,0 +1 @@ +/node_modules/ diff --git a/node_modules/less-middleware/lib/determine-imports.js b/node_modules/less-middleware/lib/determine-imports.js new file mode 100644 index 0000000..76a0779 --- /dev/null +++ b/node_modules/less-middleware/lib/determine-imports.js @@ -0,0 +1,91 @@ +var fs = require('fs'), + path = require('path');

[http://lesscss.org](http://lesscss.org). + +This is the JavaScript, and now official, stable version of LESS. + + +## Getting Started + +Options for adding Less.js to your project: + +* Install with [NPM](https://npmjs.org/): `npm install less` +* [Download the latest release][download] +* Clone the repo: `git clone git://github.com/less/less.js.git` + + + +## Feature Highlights +LESS extends CSS with dynamic features such as: + +* [nesting](#nesting) +* [variables](#variables) +* [operations](#operations) +* [mixins](#mixins) +* [extend](#extend) (selector inheritance) + +To learn about the many other features Less.js has to offer please visit [http://lesscss.org](http://lesscss.org) and [the Less.js wiki][wiki] + + +### Examples +#### nesting +Take advantage of nesting to make code more readable and maintainable. This: + +```less +.nav > li > a { + border: 1px solid #f5f5f5; + &:hover { + border-color: #ddd; + } +} +``` + +renders to: + +```css +.nav > li > a { + border: 1px solid #f5f5f5; +} +.nav > li > a:hover { + border-color: #ddd; +} +``` + + +#### variables +Updated commonly used values from a single location. + +```less +// Variables ("inline" comments like this can be used) +@link-color: #428bca; // appears as "sea blue" + +/* Or "block comments" that span + multiple lines, like this */ +a { + color: @link-color; // use the variable in styles +} +``` + +Variables can also be used in `@import` statements, URLs, selector names, and more. + + + +#### operations +Continuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles: + +```less +// Variables +@link-color: #428bca; +@link-color-hover: darken(@link-color, 10%); + +// Styles +a { + color: @link-color; +} +a:hover { + color: @link-color-hover; +} +``` +renders to: + +```css +a { + color: #428bca; +} +a:hover { + color: #3071a9; +} +``` + +#### mixins +##### "implicit" mixins +Mixins enable you to apply the styles of one selector inside another selector like this: + +```less +// Variables +@link-color: #428bca; + +// Any "regular" class... +.link { + color: @link-color; +} +a { + font-weight: bold; + .link; // ...can be used as an "implicit" mixin +} +``` + +renders to: + +```css +.link { + color: #428bca; +} +a { + font-weight: bold; + color: #428bca; +} +``` + +So any selector can be an "implicit mixin". We'll show you a DRYer way to do this below. + + + +##### parametric mixins +Mixins can also accept parameters: + +```less +// Transition mixin +.transition(@transition) { + -webkit-transition: @transition; + -moz-transition: @transition; + -o-transition: @transition; + transition: @transition; +} +``` + +used like this: + +```less +// Variables +@link-color: #428bca; +@link-color-hover: darken(@link-color, 10%); + +//Transition mixin would be anywhere here + +a { + font-weight: bold; + color: @link-color; + .transition(color .2s ease-in-out); + // Hover state + &:hover { + color: @link-color-hover; + } +} +``` + +renders to: + +```css +a { + font-weight: bold; + color: #428bca; + -webkit-transition: color 0.2s ease-in-out; + -moz-transition: color 0.2s ease-in-out; + -o-transition: color 0.2s ease-in-out; + transition: color 0.2s ease-in-out; +} +a:hover { + color: #3071a9; +} +``` + + +#### extend +The `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of "borrowing styles", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this: + +```less +// Variables +@link-color: #428bca; + +.link { + color: @link-color; +} +a:extend(.link) { + font-weight: bold; +} +// Can also be written as +a { + &:extend(.link); + font-weight: bold; +} +``` + +renders to: + +```css +.link, a { + color: #428bca; +} +a { + font-weight: bold; +} +``` + +## Usage + +### Compiling and Parsing +Invoke the compiler from node: + +```javascript +var less = require('less'); + +less.render('.class { width: (1 + 1) }', function (e, css) { + console.log(css); +}); +``` + +Outputs: + +```css +.class { + width: 2; +} +``` + +You may also manually invoke the parser and compiler: + +```javascript +var parser = new(less.Parser); + +parser.parse('.class { width: (1 + 1) }', function (err, tree) { + if (err) { return console.error(err) } + console.log(tree.toCSS()); +}); +``` + + +### Configuration +You may also pass options to the compiler: + +```javascript +var parser = new(less.Parser)({ + paths: ['.', './src/less'], // Specify search paths for @import directives + filename: 'style.less' // Specify a filename, for better error messages +}); + +parser.parse('.class { width: (1 + 1) }', function (e, tree) { + tree.toCSS({ compress: true }); // Minify CSS output +}); +``` + +## More information + +For general information on the language, configuration options or usage visit [lesscss.org](http://lesscss.org) or [the less wiki][wiki]. + +Here are other resources for using Less.js: + +* [stackoverflow.com][so] is a great place to get answers about Less. +* [node.js tools](https://github.com/less/less.js/wiki/Converting-LESS-to-CSS) for converting Less to CSS +* [GUI compilers for Less](https://github.com/less/less.js/wiki/GUI-compilers-that-use-LESS.js) +* [Less.js Issues][issues] for reporting bugs + + + +## Contributing +Please read [CONTRIBUTING.md](./CONTRIBUTING.md).

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js. + +The Less.js [Gruntfile](Gruntfile.js) is configured with the following "convenience tasks" : + +#### test - `grunt` +Runs jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run. + +#### test - `grunt benchmark` +Runs the benchmark suite. + +#### build for testing browser - 'grunt browser' +This builds less.js and puts it in 'test/browser/less.js' + +#### build - `grunt stable | grunt beta | grunt alpha` +Builds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request. + +#### readme - `grunt readme` +Build the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct. + +Please review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks. + +**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help. + + +## Release History +See the [changelog](CHANGELOG.md) + +## [License](LICENSE) + +Copyright (c) 2009-2014 [Alexis Sellier](http://cloudhead.io/) & The Core Less Team +Licensed under the [Apache License](LICENSE). + + +[so]: http://stackoverflow.com/questions/tagged/twitter-bootstrap+less "StackOverflow.com" +[issues]: https://github.com/less/less.js/issues "GitHub Issues for Less.js" +[wiki]: https://github.com/less/less.js/wiki "The official wiki for Less.js" +[download]: https://github.com/less/less.js/zipball/master "Download Less.js" \ No newline at end of file diff --git a/node_modules/less-middleware/node_modules/less/benchmark/benchmark.less b/node_modules/less-middleware/node_modules/less/benchmark/benchmark.less new file mode 100644 index 0000000..c9c0f66 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/benchmark/benchmark.less @@ -0,0 +1,3979 @@ +@bg: #f01;

This: + +```less +.nav > li > a { + border: 1px solid #f5f5f5; + &:hover { + border-color: #ddd; + } +} +``` + +renders to: + +```css +.nav > li > a { + border: 1px solid #f5f5f5; +} +.nav > li > a:hover { + border-color: #ddd; +} +``` + + +#### variables +Updated commonly used values from a single location. + +```less +// Variables ("inline" comments like this can be used) +@link-color: #428bca; // appears as "sea blue" + +/* Or "block comments" that span + multiple lines, like this */ +a { + color: @link-color; // use the variable in styles +} +``` + +Variables can also be used in `@import` statements, URLs, selector names, and more. + + + +#### operations +Continuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles: + +```less +// Variables +@link-color: #428bca; +@link-color-hover: darken(@link-color, 10%); + +// Styles +a { + color: @link-color; +} +a:hover { + color: @link-color-hover; +} +``` +renders to: + +```css +a { + color: #428bca; +} +a:hover { + color: #3071a9; +} +``` + +#### mixins +##### "implicit" mixins +Mixins enable you to apply the styles of one selector inside another selector like this: + +```less +// Variables +@link-color: #428bca; + +// Any "regular" class... +.link { + color: @link-color; +} +a { + font-weight: bold; + .link; // ...can be used as an "implicit" mixin +} +``` + +renders to: + +```css +.link { + color: #428bca; +} +a { + font-weight: bold; + color: #428bca; +} +``` + +So any selector can be an "implicit mixin". We'll show you a DRYer way to do this below. + + + +##### parametric mixins +Mixins can also accept parameters: + +```less +// Transition mixin +.transition(@transition) { + -webkit-transition: @transition; + -moz-transition: @transition; + -o-transition: @transition; + transition: @transition; +} +``` + +used like this: + +```less +// Variables +@link-color: #428bca; +@link-color-hover: darken(@link-color, 10%); + +//Transition mixin would be anywhere here + +a { + font-weight: bold; + color: @link-color; + .transition(color .2s ease-in-out); + // Hover state + &:hover { + color: @link-color-hover; + } +} +``` + +renders to: + +```css +a { + font-weight: bold; + color: #428bca; + -webkit-transition: color 0.2s ease-in-out; + -moz-transition: color 0.2s ease-in-out; + -o-transition: color 0.2s ease-in-out; + transition: color 0.2s ease-in-out; +} +a:hover { + color: #3071a9; +} +``` + + +#### extend +The `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of "borrowing styles", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this: + +```less +// Variables +@link-color: #428bca; + +.link { + color: @link-color; +} +a:extend(.link) { + font-weight: bold; +} +// Can also be written as +a { + &:extend(.link); + font-weight: bold; +} +``` + +renders to: + +```css +.link, a { + color: #428bca; +} +a { + font-weight: bold; +} +``` + +## Usage + +### Compiling and Parsing +Invoke the compiler from node: + +```javascript +var less = require('less'); + +less.render('.class { width: (1 + 1) }', function (e, css) { + console.log(css); +}); +``` + +Outputs: + +```css +.class { + width: 2; +} +``` + +You may also manually invoke the parser and compiler: + +```javascript +var parser = new(less.Parser); + +parser.parse('.class { width: (1 + 1) }', function (err, tree) { + if (err) { return console.error(err) } + console.log(tree.toCSS()); +}); +``` + + +### Configuration +You may also pass options to the compiler: + +```javascript +var parser = new(less.Parser)({ + paths: ['.', './src/less'], // Specify search paths for @import directives + filename: 'style.less' // Specify a filename, for better error messages +}); + +parser.parse('.class { width: (1 + 1) }', function (e, tree) { + tree.toCSS({ compress: true }); // Minify CSS output +}); +``` + +## More information + +For general information on the language, configuration options or usage visit [lesscss.org](http://lesscss.org) or [the less wiki][wiki]. + +Here are other resources for using Less.js: + +* [stackoverflow.com][so] is a great place to get answers about Less. +* [node.js tools](https://github.com/less/less.js/wiki/Converting-LESS-to-CSS) for converting Less to CSS +* [GUI compilers for Less](https://github.com/less/less.js/wiki/GUI-compilers-that-use-LESS.js) +* [Less.js Issues][issues] for reporting bugs + + + +## Contributing +Please read [CONTRIBUTING.md](./CONTRIBUTING.md).

If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js. + +The Less.js [Gruntfile](Gruntfile.js) is configured with the following "convenience tasks" : + +#### test - `grunt` +Runs jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run. + +#### test - `grunt benchmark` +Runs the benchmark suite. + +#### build for testing browser - 'grunt browser' +This builds less.js and puts it in 'test/browser/less.js' + +#### build - `grunt stable | grunt beta | grunt alpha` +Builds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request. + +#### readme - `grunt readme` +Build the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct. + +Please review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks. + +**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help. + + +## Release History +See the [changelog](CHANGELOG.md) + +## [License](LICENSE) + +Copyright (c) 2009-<%= grunt.template.today("yyyy") %> [Alexis Sellier](http://cloudhead.io/) & The Core Less Team +Licensed under the [Apache License](LICENSE). + + +[so]: http://stackoverflow.com/questions/tagged/twitter-bootstrap+less "StackOverflow.com" +[issues]: https://github.com/less/less.js/issues "GitHub Issues for Less.js" +[wiki]: https://github.com/less/less.js/wiki "The official wiki for Less.js" +[download]: https://github.com/less/less.js/zipball/master "Download Less.js" \ No newline at end of file diff --git a/node_modules/less-middleware/node_modules/less/build/amd.js b/node_modules/less-middleware/node_modules/less/build/amd.js new file mode 100644 index 0000000..7d7e33c --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/build/amd.js @@ -0,0 +1,6 @@ +// amd.js +// +// Define Less as an AMD module. +if (typeof define === "function" && define.amd) { + define(function () { return less; } ); +} diff --git a/node_modules/less-middleware/node_modules/less/build/browser-header.js b/node_modules/less-middleware/node_modules/less/build/browser-header.js new file mode 100644 index 0000000..eaff5bf --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/build/browser-header.js @@ -0,0 +1,4 @@ +if (typeof(window.less) === 'undefined' || typeof(window.less.nodeType) !== 'undefined') { window.less = {}; } +less = window.less; +tree = window.less.tree = {}; +less.mode = 'browser'; diff --git a/node_modules/less-middleware/node_modules/less/build/build.yml b/node_modules/less-middleware/node_modules/less/build/build.yml new file mode 100644 index 0000000..dd4236b --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/build/build.yml @@ -0,0 +1,160 @@ +### +# NOTICE: +# this file is specifically for controlling +# paths for Less.js source files, as well as +# the order in which source files are +# concatenated. +# +# Please do not add paths for anything else +# to this file.

Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS. This gives us a 50% speed-up in the parser, +// and a smaller speed-up in the code-gen. +// +// +// Token matching is done with the `$` function, which either takes +// a terminal string or regexp, or a non-terminal function to call. +// It also takes care of moving all the indices forwards. +// +// +less.Parser = function Parser(env) { + var input, // LeSS input string + i, // current index in `input` + j, // current chunk + temp, // temporarily holds a chunk's state, for backtracking + memo, // temporarily holds `i`, when backtracking + furthest, // furthest index the parser has gone to + chunks, // chunkified input + current, // index of current chunk, in `input` + parser; + + var that = this; + + // This function is called after all files + // have been imported through `@import`. + var finish = function () {}; + + var imports = this.imports = { + paths: env && env.paths || [], // Search paths, when importing + queue: [], // Files which haven't been imported yet + files: {}, // Holds the imported parse trees + mime: env && env.mime, // MIME type of .less files + push: function (path, callback) { + var that = this; + this.queue.push(path); + + // + // Import a file asynchronously + // + less.Parser.importer(path, this.paths, function (root) { + that.queue.splice(that.queue.indexOf(path), 1); // Remove the path from the queue + that.files[path] = root; // Store the root + + callback(root); + + if (that.queue.length === 0) { finish() } // Call `finish` if we're done importing + }, env); + } + }; + + function save() { temp = chunks[j], memo = i, current = i } + function restore() { chunks[j] = temp, i = memo, current = i } + + function sync() { + if (i > current) { + chunks[j] = chunks[j].slice(i - current); + current = i; + } + } + // + // Parse from a token, regexp or string, and move forward if match + // + function $(tok) { + var match, args, length, c, index, endIndex, k, mem; + + // + // Non-terminal + // + if (tok instanceof Function) { + return tok.call(parser.parsers); + // + // Terminal + // + // Either match a single character in the input, + // or match a regexp in the current chunk (chunk[j]). + // + } else if (typeof(tok) === 'string') { + match = input.charAt(i) === tok ? tok : null; + length = 1; + sync (); + } else { + sync (); + + if (match = tok.exec(chunks[j])) { + length = match[0].length; + } else { + return null; + } + } + + // The match is confirmed, add the match length to `i`, + // and consume any extra white-space characters (' ' || '\n') + // which come after that.

in the browser, several +// optimization had to be made: +// +// - Matching and slicing on a huge input is often cause of slowdowns. +// The solution is to chunkify the input into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

+// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

into smaller strings. +// The chunks are stored in the `chunks` var, +// `j` holds the current chunk index, and `current` holds +// the index of the current chunk in relation to `input`. +// This gives us an almost 4x speed-up. +// +// - In many cases, we don't need to match individual tokens; +// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +//

+// for example, if a value doesn't hold any variables, operations +// or dynamic references, the parser can effectively 'skip' it, +// treating it as a literal. +// An example would be '1px solid #000' - which evaluates to itself, +// we don't need to know what the individual components are. +// The drawback, of course is that you don't get the benefits of +// syntax-checking on the CSS.

The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('commander');\n\nprogram\n .version('0.0.1')\n .option('-p, --peppers', 'Add peppers')\n .option('-P, --pineapple', 'Add pineapple')\n .option('-b, --bbq', 'Add bbq sauce')\n .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')\n .parse(process.argv);\n\nconsole.log('you ordered a pizza with:');\nif (program.peppers) console.log(' - peppers');\nif (program.pineapple) console.log(' - pineapple');\nif (program.bbq) console.log(' - bbq');\nconsole.log(' - %s cheese', program.cheese);\n```\n\n Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as \"--template-engine\" are camel-cased, becoming `program.templateEngine` etc.\n\n## Automated --help\n\n The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:\n\n``` \n $ ./examples/pizza --help\n\n Usage: pizza [options]\n\n Options:\n\n -V, --version output the version number\n -p, --peppers Add peppers\n -P, --pineapple Add pineapple\n -b, --bbq Add bbq sauce\n -c, --cheese Add the specified type of cheese [marble]\n -h, --help output usage information\n\n```\n\n## Coercion\n\n```js\nfunction range(val) {\n return val.split('..').map(Number);\n}\n\nfunction list(val) {\n return val.split(',');\n}\n\nprogram\n .version('0.0.1')\n .usage('[options] ')\n .option('-i, --integer ', 'An integer argument', parseInt)\n .option('-f, --float ', 'A float argument', parseFloat)\n .option('-r, --range ..', 'A range', range)\n .option('-l, --list ', 'A list', list)\n .option('-o, --optional [value]', 'An optional value')\n .parse(process.argv);\n\nconsole.log(' int: %j', program.integer);\nconsole.log(' float: %j', program.float);\nconsole.log(' optional: %j', program.optional);\nprogram.range = program.range || [];\nconsole.log(' range: %j..%j', program.range[0], program.range[1]);\nconsole.log(' list: %j', program.list);\nconsole.log(' args: %j', program.args);\n```\n\n## Custom help\n\n You can display arbitrary `-h, --help` information\n by listening for \"--help\". Commander will automatically\n exit once you are done so that the remainder of your program\n does not execute causing undesired behaviours, for example\n in the following executable \"stuff\" will not output when\n `--help` is used.\n\n```js\n#!/usr/bin/env node\n\n/**\n * Module dependencies.\n */\n\nvar program = require('../');\n\nfunction list(val) {\n return val.split(',').map(Number);\n}\n\nprogram\n .version('0.0.1')\n .option('-f, --foo', 'enable some foo')\n .option('-b, --bar', 'enable some bar')\n .option('-B, --baz', 'enable some baz');\n\n// must be before .parse() since\n// node's emit() is immediate\n\nprogram.on('--help', function(){\n console.log(' Examples:');\n console.log('');\n console.log(' $ custom-help --help');\n console.log(' $ custom-help -h');\n console.log('');\n});\n\nprogram.parse(process.argv);\n\nconsole.log('stuff');\n```\n\nyielding the following help output:\n\n```\n\nUsage: custom-help [options]\n\nOptions:\n\n -h, --help output usage information\n -V, --version output the version number\n -f, --foo enable some foo\n -b, --bar enable some bar\n -B, --baz enable some baz\n\nExamples:\n\n $ custom-help --help\n $ custom-help -h\n\n```\n\n## .outputHelp()\n\n Output help information without exiting.\n\n## .help()\n\n Output help information and exit immediately.\n\n## Links\n\n -

That's it!\n\n#### Node.js module\n\nUpdate `clean-css` as for CLI above.\nThen change your JavaScript code from:\n\n```js\nvar minimized = CleanCSS.process(source, options);\n```\n\ninto\n\n```js\nvar minimized = new CleanCSS(options).minify(source);\n```\n\nAnd you are done.\n\n### How to use clean-css CLI?\n\nClean-css accepts the following command line arguments (please make sure\nyou use `` as the very last argument to avoid potential issues):\n\n```\ncleancss [options] \n\n-h, --help Output usage information\n-v, --version Output the version number\n-b, --keep-line-breaks Keep line breaks\n--s0 Remove all special comments, i.e. /*! comment */\n--s1 Remove all special comments but the first one\n-r, --root [root-path] A root path to which resolve absolute @import rules\n and rebase relative URLs\n-o, --output [output-file] Use [output-file] as output instead of STDOUT\n-s, --skip-import Disable @import processing\n--skip-rebase Disable URLs rebasing\n--skip-advanced Disable advanced optimizations - selector & property merging,\n reduction, etc.\n--selectors-merge-mode [ie8|*] Use `ie8` for compatibility mode, `*` for merge all (default)\n-d, --debug Shows debug information (minification time & compression efficiency)\n```\n\n#### Examples:\n\nTo minify a **public.css** file into **public-min.css** do:\n\n```\ncleancss -o public-min.css public.css\n```\n\nTo minify the same **public.css** into the standard output skip the `-o` parameter:\n\n```\ncleancss public.css\n```\n\nMore likely you would like to concatenate a couple of files.\nIf you are on a Unix-like system:\n\n```bash\ncat one.css two.css three.css | cleancss -o merged-and-minified.css\n```\n\nOn Windows:\n\n```bat\ntype one.css two.css three.css | cleancss -o merged-and-minified.css\n```\n\nOr even gzip the result at once:\n\n```bash\ncat one.css two.css three.css | cleancss | gzip -9 -c > merged-minified-and-gzipped.css.gz\n```\n\n### How to use clean-css programmatically?\n\n```js\nvar CleanCSS = require('clean-css');\nvar source = 'a{font-weight:bold;}';\nvar minimized = new CleanCSS().minify(source);\n```\n\nCleanCSS constructor accepts a hash as a parameter, i.e.,\n`new CleanCSS(options).minify(source)` with the following options available:\n\n* `keepSpecialComments` - `*` for keeping all (default), `1` for keeping first one only, `0` for removing all\n* `keepBreaks` - whether to keep line breaks (default is false)\n* `benchmark` - turns on benchmarking mode measuring time spent on cleaning up\n (run `npm run bench` to see example)\n* `root` - path to resolve absolute `@import` rules and rebase relative URLs\n* `relativeTo` - path with which to resolve relative `@import` rules and URLs\n* `processImport` - whether to process `@import` rules\n* `noRebase` - whether to skip URLs rebasing\n* `noAdvanced` - set to true to disable advanced optimizations - selector & property merging, reduction, etc.\n* `selectorsMergeMode` - `ie8` for IE8 compatibility mode, `*` for merging all (default)\n* `debug` - set to true to get minification statistics under `stats` property (see `test/custom-test.js` for examples)\n\n### What are the clean-css' dev commands?\n\nFirst clone the source, then run:\n\n* `npm run bench` for clean-css benchmarks (see [test/bench.js](https://github.com/GoalSmashers/clean-css/blob/master/test/bench.js) for details)\n* `npm run check` to check JS sources with [JSHint](https://github.com/jshint/jshint/)\n* `npm test` for the test suite\n\n## Tips & Tricks\n\n### How to preserve a comment block?\n\nUse the `/*!` notation instead of the standard one `/*`:\n\n```css\n/*!\n Important comments included in minified output.\n*/\n```\n\n### How to rebase relative image URLs\n\nClean-css will handle it automatically for you (since version 1.1) in the following cases:\n\n* When using the CLI:\n 1. Use an output path via `-o`/`--output` to rebase URLs as relative to the output file.\n 2. Use a root path via `-r`/`--root` to rebase URLs as absolute from the given root path.\n 3. If you specify both then `-r`/`--root` takes precendence.\n* When using clean-css as a library:\n 1. Use a combination of `relativeTo` and `target` options for relative rebase (same as 1 in CLI).\n 2. Use a combination of `relativeTo` and `root` options for absolute rebase (same as 2 in CLI).\n 3. `root` takes precendence over `target` as in CLI.\n\n## Acknowledgments\n\n* Vincent Voyer ([@vvo](https://github.com/vvo)) for a patch with better\n empty element regex and for inspiring us to do many performance improvements\n in 0.4 release.\n* Isaac ([@facelessuser](https://github.com/facelessuser)) for pointing out\n a flaw in clean-css' stateless mode.\n* Jan Michael Alonzo ([@jmalonzo](https://github.com/jmalonzo)) for a patch\n removing node.js' old `sys` package.\n* [@XhmikosR](https://github.com/XhmikosR) for suggesting new features\n (option to remove special comments and strip out URLs quotation) and\n pointing out numerous improvements (JSHint, media queries).\n* Anthony Barre ([@abarre](https://github.com/abarre)) for improvements to\n `@import` processing, namely introducing the `--skip-import` /\n `processImport` options.\n* Simon Altschuler ([@altschuler](https://github.com/altschuler)) for fixing\n `@import` processing inside comments.\n\n## License\n\nClean-css is released under the [MIT License](https://github.com/GoalSmashers/clean-css/blob/master/LICENSE).\n", + "readmeFilename": "README.md", + "_id": "clean-css@2.0.8", + "dist": { + "shasum": "81488c6f3e913abd903882c0493e9786565e0185" + }, + "_from": "clean-css@2.0.x", + "_resolved": "https://registry.npmjs.org/clean-css/-/clean-css-2.0.8.tgz" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/mime/LICENSE b/node_modules/less-middleware/node_modules/less/node_modules/mime/LICENSE new file mode 100644 index 0000000..451fc45 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/mime/LICENSE @@ -0,0 +1,19 @@ +Copyright (c) 2010 Benjamin Thomas, Robert Kieffer + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

When doing so, `content-type` and `content-length` are preserved in the PUT headers. + +```javascript +request.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png')) +``` + +Now let’s get fancy. + +```javascript +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + if (req.method === 'PUT') { + req.pipe(request.put('http://mysite.com/doodle.png')) + } else if (req.method === 'GET' || req.method === 'HEAD') { + request.get('http://mysite.com/doodle.png').pipe(resp) + } + } +}) +``` + +You can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do: + +```javascript +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + var x = request('http://mysite.com/doodle.png') + req.pipe(x) + x.pipe(resp) + } +}) +``` + +And since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :) + +```javascript +req.pipe(request('http://mysite.com/doodle.png')).pipe(resp) +``` + +Also, none of this new functionality conflicts with requests previous features, it just expands them. + +```javascript +var r = request.defaults({'proxy':'http://localproxy.com'}) + +http.createServer(function (req, resp) { + if (req.url === '/doodle.png') { + r.get('http://google.com/doodle.png').pipe(resp) + } +}) +``` + +You can still use intermediate proxies, the requests will still follow HTTP forwards, etc. + +## UNIX Socket + +`request` supports the `unix://` protocol for all requests. The path is assumed to be absolute to the root of the host file system. + +HTTP paths are extracted from the supplied URL by testing each level of the full URL against net.connect for a socket response. + +Thus the following request will GET `/httppath` from the HTTP server listening on `/tmp/unix.socket` + +```javascript +request.get('unix://tmp/unix.socket/httppath') +``` + +## Forms + +`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API. + +URL-encoded forms are simple. + +```javascript +request.post('http://service.com/upload', {form:{key:'value'}}) +// or +request.post('http://service.com/upload').form({key:'value'}) +``` + +For `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). You don’t need to worry about piping the form object or setting the headers, `request` will handle that for you. + +```javascript +var r = request.post('http://service.com/upload') +var form = r.form() +form.append('my_field', 'my_value') +form.append('my_buffer', new Buffer([1, 2, 3])) +form.append('my_file', fs.createReadStream(path.join(__dirname, 'doodle.png')) +form.append('remote_file', request('http://google.com/doodle.png')) +``` + +## HTTP Authentication + +```javascript +request.get('http://some.server.com/').auth('username', 'password', false); +// or +request.get('http://some.server.com/', { + 'auth': { + 'user': 'username', + 'pass': 'password', + 'sendImmediately': false + } +}); +``` + +If passed as an option, `auth` should be a hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional). The method form takes parameters `auth(username, password, sendImmediately)`. + +`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent. If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method). + +Digest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail. + +## OAuth Signing + +```javascript +// Twitter OAuth +var qs = require('querystring') + , oauth = + { callback: 'http://mysite.com/callback/' + , consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + } + , url = 'https://api.twitter.com/oauth/request_token' + ; +request.post({url:url, oauth:oauth}, function (e, r, body) { + // Ideally, you would take the body in the response + // and construct a URL that a user clicks on (like a sign in button). + // The verifier is only available in the response after a user has + // verified with twitter that they are authorizing your app. + var access_token = qs.parse(body) + , oauth = + { consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + , token: access_token.oauth_token + , verifier: access_token.oauth_verifier + } + , url = 'https://api.twitter.com/oauth/access_token' + ; + request.post({url:url, oauth:oauth}, function (e, r, body) { + var perm_token = qs.parse(body) + , oauth = + { consumer_key: CONSUMER_KEY + , consumer_secret: CONSUMER_SECRET + , token: perm_token.oauth_token + , token_secret: perm_token.oauth_token_secret + } + , url = 'https://api.twitter.com/1.1/users/show.json?' + , params = + { screen_name: perm_token.screen_name + , user_id: perm_token.user_id + } + ; + url += qs.stringify(params) + request.get({url:url, oauth:oauth, json:true}, function (e, r, user) { + console.log(user) + }) + }) +}) +``` + +### Custom HTTP Headers + +HTTP Headers, such as `User-Agent`, can be set in the `options` object. +In the example below, we call the github API to find out the number +of stars and forks for the request repository. This requires a +custom `User-Agent` header as well as https. + +```javascript +var request = require('request'); + +var options = { + url: 'https://api.github.com/repos/mikeal/request', + headers: { + 'User-Agent': 'request' + } +}; + +function callback(error, response, body) { + if (!error && response.statusCode == 200) { + var info = JSON.parse(body); + console.log(info.stargazers_count + " Stars"); + console.log(info.forks_count + " Forks"); + } +} + +request(options, callback); +``` + +### request(options, callback) + +The first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional. + +* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()` +* `qs` - object containing querystring values to be appended to the `uri` +* `method` - http method (default: `"GET"`) +* `headers` - http headers (default: `{}`) +* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`. +* `form` - when passed an object, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header. When passed no options, a `FormData` instance is returned (and is piped to request). +* `auth` - A hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional). See documentation above. +* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header. Additionally, parses the response body as JSON. +* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below. +* `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`) +* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`) +* `maxRedirects` - the maximum number of redirects to follow (default: `10`) +* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`. +* `pool` - A hash object containing the agents for these requests. If omitted, the request will use the global pool (which is set to node's default `maxSockets`) +* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool. +* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request +* `proxy` - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`) +* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above. +* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example). +* `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option. +* `jar` - If `true`, remember cookies for future use (or define your custom cookie jar; see examples section) +* `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services) +* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options. +* `localAddress` - Local interface to bind for network connections. + + +The callback argument gets 3 arguments: + +1.

+form.append('my_buffer', new Buffer(10)); +form.append('my_logo', request('http://nodejs.org/images/logo.png')); +``` + +In order to submit this form to a web application, call ```submit(url, [callback])``` method: + +``` javascript +form.submit('http://example.org/', function(err, res) { + // res – response object (http.IncomingMessage) // + res.resume(); // for node-0.10.x +}); + +``` + +For more advanced request manipulations ```submit()``` method returns ```http.ClientRequest``` object, or you can choose from one of the alternative submission methods. + +### Alternative submission methods + +You can use node's http client interface: + +``` javascript +var http = require('http');

+ +form.submit('http://example.com/', function(err, res) { + if (err) throw err; + console.log('Done'); +}); +``` + +Form-Data can recognize and fetch all the required information from common types of streams (```fs.readStream```, ```http.response``` and ```mikeal's request```), for some other types of streams you'd need to provide "file"-related information manually: + +``` javascript +someModule.stream(function(err, stdout, stderr) { + if (err) throw err; + + var form = new FormData(); + + form.append('file', stdout, { + filename: 'unicycle.jpg', + contentType: 'image/jpg', + knownLength: 19806 + }); + + form.submit('http://example.com/', function(err, res) { + if (err) throw err; + console.log('Done'); + }); +}); +``` + +For edge cases, like POST request to URL with query string or to pass HTTP auth credentials, object can be passed to `form.submit()` as first parameter: + +``` javascript +form.submit({ + host: 'example.com', + path: '/probably.php?extra=params', + auth: 'username:password' +}, function(err, res) { + console.log(res.statusCode);

Although originally designed for +use with [node.js](http://nodejs.org), it can also be used directly in the +browser. Also supports [component](https://github.com/component/component). + +Async provides around 20 functions that include the usual 'functional' +suspects (map, reduce, filter, each…) as well as some common patterns +for asynchronous control flow (parallel, series, waterfall…). All these +functions assume you follow the node.js convention of providing a single +callback as the last argument of your async function. + + +## Quick Examples + +```javascript +async.map(['file1','file2','file3'], fs.stat, function(err, results){ + // results is now an array of stats for each file +}); + +async.filter(['file1','file2','file3'], fs.exists, function(results){ + // results now equals an array of the existing files +}); + +async.parallel([ + function(){ ... }, + function(){ ... } +], callback); + +async.series([ + function(){ ... }, + function(){ ... } +]); +``` + +There are many more functions available so take a look at the docs below for a +full list. This module aims to be comprehensive, so if you feel anything is +missing please create a GitHub issue for it. + +## Common Pitfalls + +### Binding a context to an iterator + +This section is really about bind, not about async.

Now the square function will be executed in its + // 'home' AsyncSquaringLibrary context and the value of `this.squareExponent` + // will be as expected. +}); +``` + +## Download + +The source is available for download from +[GitHub](http://github.com/caolan/async). +Alternatively, you can install using Node Package Manager (npm): + + npm install async + +__Development:__ [async.js](https://github.com/caolan/async/raw/master/lib/async.js) - 29.6kb Uncompressed + +## In the Browser + +So far it's been tested in IE6, IE7, IE8, FF3.6 and Chrome 5.

Results will always be passed + but if an error occurred, no other tasks will be performed, and the results + object will only contain partial results. + + +__Example__ + +```js +async.auto({ + get_data: function(callback){ + // async code to get some data + }, + make_folder: function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + }, + write_file: ['get_data', 'make_folder', function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + callback(null, filename); + }], + email_link: ['write_file', function(callback, results){ + // once the file is written let's email a link to it... + // results.write_file contains the filename returned by write_file. + }] +}); +``` + +This is a fairly trivial example, but to do this using the basic parallel and +series functions would look like this: + +```js +async.parallel([ + function(callback){ + // async code to get some data + }, + function(callback){ + // async code to create a directory to store a file in + // this is run at the same time as getting the data + } +], +function(err, results){ + async.series([ + function(callback){ + // once there is some data and the directory exists, + // write the data to a file in the directory + }, + function(callback){ + // once the file is written let's email a link to it... + } + ]); +}); +``` + +For a complicated series of async tasks using the auto function makes adding +new tasks much easier and makes the code more readable. + + +--------------------------------------- + + +### iterator(tasks) + +Creates an iterator function which calls the next function in the array, +returning a continuation to call the next one after that. It's also possible to +'peek' the next iterator by doing iterator.next(). + +This function is used internally by the async module but can be useful when +you want to manually control the flow of functions in series. + +__Arguments__ + +* tasks - An array of functions to run. + +__Example__ + +```js +var iterator = async.iterator([ + function(){ sys.p('one'); }, + function(){ sys.p('two'); }, + function(){ sys.p('three'); } +]); + +node> var iterator2 = iterator(); +'one' +node> var iterator3 = iterator2(); +'two' +node> iterator3(); +'three' +node> var nextfn = iterator2.next(); +node> nextfn(); +'three' +``` + +--------------------------------------- + + +### apply(function, arguments..) + +Creates a continuation function with some arguments already applied, a useful +shorthand when combined with other control flow functions. Any arguments +passed to the returned function are added to the arguments originally passed +to apply. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to automatically apply when the + continuation is called. + +__Example__ + +```js +// using apply + +async.parallel([ + async.apply(fs.writeFile, 'testfile1', 'test1'), + async.apply(fs.writeFile, 'testfile2', 'test2'), +]); + + +// the same process without using apply + +async.parallel([ + function(callback){ + fs.writeFile('testfile1', 'test1', callback); + }, + function(callback){ + fs.writeFile('testfile2', 'test2', callback); + } +]); +``` + +It's possible to pass any number of additional arguments when calling the +continuation: + +```js +node> var fn = async.apply(sys.puts, 'one'); +node> fn('two', 'three'); +one +two +three +``` + +--------------------------------------- + + +### nextTick(callback) + +Calls the callback on a later loop around the event loop. In node.js this just +calls process.nextTick, in the browser it falls back to setImmediate(callback) +if available, otherwise setTimeout(callback, 0), which means other higher priority +events may precede the execution of the callback. + +This is used internally for browser-compatibility purposes. + +__Arguments__ + +* callback - The function to call on a later loop around the event loop. + +__Example__ + +```js +var call_order = []; +async.nextTick(function(){ + call_order.push('two'); + // call_order now equals ['one','two'] +}); +call_order.push('one') +``` + + +### times(n, callback) + +Calls the callback n times and accumulates results in the same manner +you would use with async.map. + +__Arguments__ + +* n - The number of times to run the function. +* callback - The function to call n times. + +__Example__ + +```js +// Pretend this is some complicated async factory +var createUser = function(id, callback) { + callback(null, { + id: 'user' + id + }) +} +// generate 5 users +async.times(5, function(n, next){ + createUser(n, function(err, user) { + next(err, user) + }) +}, function(err, users) { + // we should now have 5 users +}); +``` + + +### timesSeries(n, callback) + +The same as times only the iterator is applied to each item in the array in +series. The next iterator is only called once the current one has completed +processing. The results array will be in the same order as the original. + + +## Utils + + +### memoize(fn, [hasher]) + +Caches the results of an async function. When creating a hash to store function +results against, the callback is omitted from the hash and an optional hash +function can be used. + +The cache of results is exposed as the `memo` property of the function returned +by `memoize`. + +__Arguments__ + +* fn - the function you to proxy and cache results from. +* hasher - an optional function for generating a custom hash for storing + results, it has all the arguments applied to it apart from the callback, and + must be synchronous. + +__Example__ + +```js +var slow_fn = function (name, callback) { + // do something + callback(null, result); +}; +var fn = async.memoize(slow_fn); + +// fn can now be used as if it were slow_fn +fn('some name', function () { + // callback +}); +``` + + +### unmemoize(fn) + +Undoes a memoized function, reverting it to the original, unmemoized +form. Comes handy in tests. + +__Arguments__ + +* fn - the memoized function + + +### log(function, arguments) + +Logs the result of an async function to the console. Only works in node.js or +in browsers that support console.log and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.log is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, 'hello ' + name); + }, 1000); +}; +``` +```js +node> async.log(hello, 'world'); +'hello world' +``` + +--------------------------------------- + + +### dir(function, arguments) + +Logs the result of an async function to the console using console.dir to +display the properties of the resulting object. Only works in node.js or +in browsers that support console.dir and console.error (such as FF and Chrome). +If multiple arguments are returned from the async function, console.dir is +called on each argument in order. + +__Arguments__ + +* function - The function you want to eventually apply all arguments to. +* arguments... - Any number of arguments to apply to the function. + +__Example__ + +```js +var hello = function(name, callback){ + setTimeout(function(){ + callback(null, {hello: name}); + }, 1000); +}; +``` +```js +node> async.dir(hello, 'world'); +{hello: 'world'} +``` + +--------------------------------------- + + +### noConflict() + +Changes the value of async back to its original value, returning a reference to the +async object. diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/component.json b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/component.json new file mode 100644 index 0000000..bbb0115 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/component.json @@ -0,0 +1,11 @@ +{ + "name": "async", + "repo": "caolan/async", + "description": "Higher-order functions and common patterns for asynchronous code", + "version": "0.1.23", + "keywords": [], + "dependencies": {}, + "development": {}, + "main": "lib/async.js", + "scripts": [ "lib/async.js" ] +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/lib/async.js b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/lib/async.js new file mode 100755 index 0000000..1eebb15 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/async/lib/async.js @@ -0,0 +1,958 @@ +/*global setImmediate: false, setTimeout: false, console: false */ +(function () { + + var async = {};

If the iterator passes an error to this callback, the main\ncallback for the each function is immediately called with the error.\n\nNote, that since this function applies the iterator to each item in parallel\nthere is no guarantee that the iterator functions will complete in order.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err) which must be called once it has \n completed. If no error has occured, the callback should be run without \n arguments or with an explicit null argument.\n* callback(err) - A callback which is called after all the iterator functions\n have finished, or an error has occurred.\n\n__Example__\n\n```js\n// assuming openFiles is an array of file names and saveFile is a function\n// to save the modified contents of that file:\n\nasync.each(openFiles, saveFile, function(err){\n // if any of the saves produced an error, err would equal that error\n});\n```\n\n---------------------------------------\n\n\n\n### eachSeries(arr, iterator, callback)\n\nThe same as each only the iterator is applied to each item in the array in\nseries. The next iterator is only called once the current one has completed\nprocessing. This means the iterator functions will complete in order.\n\n\n---------------------------------------\n\n\n\n### eachLimit(arr, limit, iterator, callback)\n\nThe same as each only no more than \"limit\" iterators will be simultaneously \nrunning at any time.\n\nNote that the items are not processed in batches, so there is no guarantee that\n the first \"limit\" iterator functions will complete before any others are \nstarted.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* limit - The maximum number of iterators to run at any time.\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err) which must be called once it has \n completed. If no error has occured, the callback should be run without \n arguments or with an explicit null argument.\n* callback(err) - A callback which is called after all the iterator functions\n have finished, or an error has occurred.\n\n__Example__\n\n```js\n// Assume documents is an array of JSON objects and requestApi is a\n// function that interacts with a rate-limited REST api.\n\nasync.eachLimit(documents, 20, requestApi, function(err){\n // if any of the saves produced an error, err would equal that error\n});\n```\n\n---------------------------------------\n\n\n### map(arr, iterator, callback)\n\nProduces a new array of values by mapping each value in the given array through\nthe iterator function. The iterator is called with an item from the array and a\ncallback for when it has finished processing. The callback takes 2 arguments, \nan error and the transformed item from the array. If the iterator passes an\nerror to this callback, the main callback for the map function is immediately\ncalled with the error.\n\nNote, that since this function applies the iterator to each item in parallel\nthere is no guarantee that the iterator functions will complete in order, however\nthe results array will be in the same order as the original array.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err, transformed) which must be called once \n it has completed with an error (which can be null) and a transformed item.\n* callback(err, results) - A callback which is called after all the iterator\n functions have finished, or an error has occurred. Results is an array of the\n transformed items from the original array.\n\n__Example__\n\n```js\nasync.map(['file1','file2','file3'], fs.stat, function(err, results){\n // results is now an array of stats for each file\n});\n```\n\n---------------------------------------\n\n\n### mapSeries(arr, iterator, callback)\n\nThe same as map only the iterator is applied to each item in the array in\nseries. The next iterator is only called once the current one has completed\nprocessing. The results array will be in the same order as the original.\n\n\n---------------------------------------\n\n\n### mapLimit(arr, limit, iterator, callback)\n\nThe same as map only no more than \"limit\" iterators will be simultaneously \nrunning at any time.\n\nNote that the items are not processed in batches, so there is no guarantee that\n the first \"limit\" iterator functions will complete before any others are \nstarted.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* limit - The maximum number of iterators to run at any time.\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err, transformed) which must be called once \n it has completed with an error (which can be null) and a transformed item.\n* callback(err, results) - A callback which is called after all the iterator\n functions have finished, or an error has occurred. Results is an array of the\n transformed items from the original array.\n\n__Example__\n\n```js\nasync.mapLimit(['file1','file2','file3'], 1, fs.stat, function(err, results){\n // results is now an array of stats for each file\n});\n```\n\n---------------------------------------\n\n\n### filter(arr, iterator, callback)\n\n__Alias:__ select\n\nReturns a new array of all the values which pass an async truth test.\n_The callback for each iterator call only accepts a single argument of true or\nfalse, it does not accept an error argument first!_ This is in-line with the\nway node libraries work with truth tests like fs.exists. This operation is\nperformed in parallel, but the results array will be in the same order as the\noriginal.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A truth test to apply to each item in the array.\n The iterator is passed a callback(truthValue) which must be called with a \n boolean argument once it has completed.\n* callback(results) - A callback which is called after all the iterator\n functions have finished.\n\n__Example__\n\n```js\nasync.filter(['file1','file2','file3'], fs.exists, function(results){\n // results now equals an array of the existing files\n});\n```\n\n---------------------------------------\n\n\n### filterSeries(arr, iterator, callback)\n\n__alias:__ selectSeries\n\nThe same as filter only the iterator is applied to each item in the array in\nseries. The next iterator is only called once the current one has completed\nprocessing. The results array will be in the same order as the original.\n\n---------------------------------------\n\n\n### reject(arr, iterator, callback)\n\nThe opposite of filter. Removes values that pass an async truth test.\n\n---------------------------------------\n\n\n### rejectSeries(arr, iterator, callback)\n\nThe same as reject, only the iterator is applied to each item in the array\nin series.\n\n\n---------------------------------------\n\n\n### reduce(arr, memo, iterator, callback)\n\n__aliases:__ inject, foldl\n\nReduces a list of values into a single value using an async iterator to return\neach successive step. Memo is the initial state of the reduction. This\nfunction only operates in series. For performance reasons, it may make sense to\nsplit a call to this function into a parallel map, then use the normal\nArray.prototype.reduce on the results. This function is for situations where\neach step in the reduction needs to be async, if you can get the data before\nreducing it then it's probably a good idea to do so.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* memo - The initial state of the reduction.\n* iterator(memo, item, callback) - A function applied to each item in the\n array to produce the next step in the reduction. The iterator is passed a\n callback(err, reduction) which accepts an optional error as its first \n argument, and the state of the reduction as the second. If an error is \n passed to the callback, the reduction is stopped and the main callback is \n immediately called with the error.\n* callback(err, result) - A callback which is called after all the iterator\n functions have finished. Result is the reduced value.\n\n__Example__\n\n```js\nasync.reduce([1,2,3], 0, function(memo, item, callback){\n // pointless async:\n process.nextTick(function(){\n callback(null, memo + item)\n });\n}, function(err, result){\n // result is now equal to the last value of memo, which is 6\n});\n```\n\n---------------------------------------\n\n\n### reduceRight(arr, memo, iterator, callback)\n\n__Alias:__ foldr\n\nSame as reduce, only operates on the items in the array in reverse order.\n\n\n---------------------------------------\n\n\n### detect(arr, iterator, callback)\n\nReturns the first value in a list that passes an async truth test. The\niterator is applied in parallel, meaning the first iterator to return true will\nfire the detect callback with that result. That means the result might not be\nthe first item in the original array (in terms of order) that passes the test.\n\nIf order within the original array is important then look at detectSeries.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A truth test to apply to each item in the array.\n The iterator is passed a callback(truthValue) which must be called with a \n boolean argument once it has completed.\n* callback(result) - A callback which is called as soon as any iterator returns\n true, or after all the iterator functions have finished. Result will be\n the first item in the array that passes the truth test (iterator) or the\n value undefined if none passed.\n\n__Example__\n\n```js\nasync.detect(['file1','file2','file3'], fs.exists, function(result){\n // result now equals the first file in the list that exists\n});\n```\n\n---------------------------------------\n\n\n### detectSeries(arr, iterator, callback)\n\nThe same as detect, only the iterator is applied to each item in the array\nin series. This means the result is always the first in the original array (in\nterms of array order) that passes the truth test.\n\n\n---------------------------------------\n\n\n### sortBy(arr, iterator, callback)\n\nSorts a list by the results of running each value through an async iterator.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err, sortValue) which must be called once it\n has completed with an error (which can be null) and a value to use as the sort\n criteria.\n* callback(err, results) - A callback which is called after all the iterator\n functions have finished, or an error has occurred. Results is the items from\n the original array sorted by the values returned by the iterator calls.\n\n__Example__\n\n```js\nasync.sortBy(['file1','file2','file3'], function(file, callback){\n fs.stat(file, function(err, stats){\n callback(err, stats.mtime);\n });\n}, function(err, results){\n // results is now the original array of files sorted by\n // modified date\n});\n```\n\n---------------------------------------\n\n\n### some(arr, iterator, callback)\n\n__Alias:__ any\n\nReturns true if at least one element in the array satisfies an async test.\n_The callback for each iterator call only accepts a single argument of true or\nfalse, it does not accept an error argument first!_ This is in-line with the\nway node libraries work with truth tests like fs.exists. Once any iterator\ncall returns true, the main callback is immediately called.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A truth test to apply to each item in the array.\n The iterator is passed a callback(truthValue) which must be called with a \n boolean argument once it has completed.\n* callback(result) - A callback which is called as soon as any iterator returns\n true, or after all the iterator functions have finished. Result will be\n either true or false depending on the values of the async tests.\n\n__Example__\n\n```js\nasync.some(['file1','file2','file3'], fs.exists, function(result){\n // if result is true then at least one of the files exists\n});\n```\n\n---------------------------------------\n\n\n### every(arr, iterator, callback)\n\n__Alias:__ all\n\nReturns true if every element in the array satisfies an async test.\n_The callback for each iterator call only accepts a single argument of true or\nfalse, it does not accept an error argument first!_ This is in-line with the\nway node libraries work with truth tests like fs.exists.\n\n__Arguments__\n\n* arr - An array to iterate over.\n* iterator(item, callback) - A truth test to apply to each item in the array.\n The iterator is passed a callback(truthValue) which must be called with a \n boolean argument once it has completed.\n* callback(result) - A callback which is called after all the iterator\n functions have finished. Result will be either true or false depending on\n the values of the async tests.\n\n__Example__\n\n```js\nasync.every(['file1','file2','file3'], fs.exists, function(result){\n // if result is true then every file exists\n});\n```\n\n---------------------------------------\n\n\n### concat(arr, iterator, callback)\n\nApplies an iterator to each item in a list, concatenating the results. Returns the\nconcatenated list. The iterators are called in parallel, and the results are\nconcatenated as they return. There is no guarantee that the results array will\nbe returned in the original order of the arguments passed to the iterator function.\n\n__Arguments__\n\n* arr - An array to iterate over\n* iterator(item, callback) - A function to apply to each item in the array.\n The iterator is passed a callback(err, results) which must be called once it \n has completed with an error (which can be null) and an array of results.\n* callback(err, results) - A callback which is called after all the iterator\n functions have finished, or an error has occurred. Results is an array containing\n the concatenated results of the iterator function.\n\n__Example__\n\n```js\nasync.concat(['dir1','dir2','dir3'], fs.readdir, function(err, files){\n // files is now a list of filenames that exist in the 3 directories\n});\n```\n\n---------------------------------------\n\n\n### concatSeries(arr, iterator, callback)\n\nSame as async.concat, but executes in series instead of parallel.\n\n\n## Control Flow\n\n\n### series(tasks, [callback])\n\nRun an array of functions in series, each one running once the previous\nfunction has completed. If any functions in the series pass an error to its\ncallback, no more functions are run and the callback for the series is\nimmediately called with the value of the error. Once the tasks have completed,\nthe results are passed to the final callback as an array.\n\nIt is also possible to use an object instead of an array. Each property will be\nrun as a function and the results will be passed to the final callback as an object\ninstead of an array. This can be a more readable way of handling results from\nasync.series.\n\n\n__Arguments__\n\n* tasks - An array or object containing functions to run, each function is passed\n a callback(err, result) it must call on completion with an error (which can\n be null) and an optional result value.\n* callback(err, results) - An optional callback to run once all the functions\n have completed. This function gets a results array (or object) containing all \n the result arguments passed to the task callbacks.\n\n__Example__\n\n```js\nasync.series([\n function(callback){\n // do some stuff ...\n callback(null, 'one');\n },\n function(callback){\n // do some more stuff ...\n callback(null, 'two');\n }\n],\n// optional callback\nfunction(err, results){\n // results is now equal to ['one', 'two']\n});\n\n\n// an example using an object instead of an array\nasync.series({\n one: function(callback){\n setTimeout(function(){\n callback(null, 1);\n }, 200);\n },\n two: function(callback){\n setTimeout(function(){\n callback(null, 2);\n }, 100);\n }\n},\nfunction(err, results) {\n // results is now equal to: {one: 1, two: 2}\n});\n```\n\n---------------------------------------\n\n\n### parallel(tasks, [callback])\n\nRun an array of functions in parallel, without waiting until the previous\nfunction has completed. If any of the functions pass an error to its\ncallback, the main callback is immediately called with the value of the error.\nOnce the tasks have completed, the results are passed to the final callback as an\narray.\n\nIt is also possible to use an object instead of an array. Each property will be\nrun as a function and the results will be passed to the final callback as an object\ninstead of an array. This can be a more readable way of handling results from\nasync.parallel.\n\n\n__Arguments__\n\n* tasks - An array or object containing functions to run, each function is passed \n a callback(err, result) it must call on completion with an error (which can\n be null) and an optional result value.\n* callback(err, results) - An optional callback to run once all the functions\n have completed. This function gets a results array (or object) containing all \n the result arguments passed to the task callbacks.\n\n__Example__\n\n```js\nasync.parallel([\n function(callback){\n setTimeout(function(){\n callback(null, 'one');\n }, 200);\n },\n function(callback){\n setTimeout(function(){\n callback(null, 'two');\n }, 100);\n }\n],\n// optional callback\nfunction(err, results){\n // the results array will equal ['one','two'] even though\n // the second function had a shorter timeout.\n});\n\n\n// an example using an object instead of an array\nasync.parallel({\n one: function(callback){\n setTimeout(function(){\n callback(null, 1);\n }, 200);\n },\n two: function(callback){\n setTimeout(function(){\n callback(null, 2);\n }, 100);\n }\n},\nfunction(err, results) {\n // results is now equals to: {one: 1, two: 2}\n});\n```\n\n---------------------------------------\n\n\n### parallelLimit(tasks, limit, [callback])\n\nThe same as parallel only the tasks are executed in parallel with a maximum of \"limit\" \ntasks executing at any time.\n\nNote that the tasks are not executed in batches, so there is no guarantee that \nthe first \"limit\" tasks will complete before any others are started.\n\n__Arguments__\n\n* tasks - An array or object containing functions to run, each function is passed \n a callback(err, result) it must call on completion with an error (which can\n be null) and an optional result value.\n* limit - The maximum number of tasks to run at any time.\n* callback(err, results) - An optional callback to run once all the functions\n have completed. This function gets a results array (or object) containing all \n the result arguments passed to the task callbacks.\n\n---------------------------------------\n\n\n### whilst(test, fn, callback)\n\nRepeatedly call fn, while test returns true. Calls the callback when stopped,\nor an error occurs.\n\n__Arguments__\n\n* test() - synchronous truth test to perform before each execution of fn.\n* fn(callback) - A function to call each time the test passes. The function is\n passed a callback(err) which must be called once it has completed with an \n optional error argument.\n* callback(err) - A callback which is called after the test fails and repeated\n execution of fn has stopped.\n\n__Example__\n\n```js\nvar count = 0;\n\nasync.whilst(\n function () { return count < 5; },\n function (callback) {\n count++;\n setTimeout(callback, 1000);\n },\n function (err) {\n // 5 seconds have passed\n }\n);\n```\n\n---------------------------------------\n\n\n### doWhilst(fn, test, callback)\n\nThe post check version of whilst. To reflect the difference in the order of operations `test` and `fn` arguments are switched. `doWhilst` is to `whilst` as `do while` is to `while` in plain JavaScript.\n\n---------------------------------------\n\n\n### until(test, fn, callback)\n\nRepeatedly call fn, until test returns true. Calls the callback when stopped,\nor an error occurs.\n\nThe inverse of async.whilst.\n\n---------------------------------------\n\n\n### doUntil(fn, test, callback)\n\nLike doWhilst except the test is inverted. Note the argument ordering differs from `until`.\n\n---------------------------------------\n\n\n### forever(fn, callback)\n\nCalls the asynchronous function 'fn' repeatedly, in series, indefinitely.\nIf an error is passed to fn's callback then 'callback' is called with the\nerror, otherwise it will never be called.\n\n---------------------------------------\n\n\n### waterfall(tasks, [callback])\n\nRuns an array of functions in series, each passing their results to the next in\nthe array. However, if any of the functions pass an error to the callback, the\nnext function is not executed and the main callback is immediately called with\nthe error.\n\n__Arguments__\n\n* tasks - An array of functions to run, each function is passed a \n callback(err, result1, result2, ...) it must call on completion. The first\n argument is an error (which can be null) and any further arguments will be \n passed as arguments in order to the next task.\n* callback(err, [results]) - An optional callback to run once all the functions\n have completed. This will be passed the results of the last task's callback.\n\n\n\n__Example__\n\n```js\nasync.waterfall([\n function(callback){\n callback(null, 'one', 'two');\n },\n function(arg1, arg2, callback){\n callback(null, 'three');\n },\n function(arg1, callback){\n // arg1 now equals 'three'\n callback(null, 'done');\n }\n], function (err, result) {\n // result now equals 'done' \n});\n```\n\n---------------------------------------\n\n### compose(fn1, fn2...)\n\nCreates a function which is a composition of the passed asynchronous\nfunctions. Each function consumes the return value of the function that\nfollows. Composing functions f(), g() and h() would produce the result of\nf(g(h())), only this version uses callbacks to obtain the return values.\n\nEach function is executed with the `this` binding of the composed function.\n\n__Arguments__\n\n* functions... - the asynchronous functions to compose\n\n\n__Example__\n\n```js\nfunction add1(n, callback) {\n setTimeout(function () {\n callback(null, n + 1);\n }, 10);\n}\n\nfunction mul3(n, callback) {\n setTimeout(function () {\n callback(null, n * 3);\n }, 10);\n}\n\nvar add1mul3 = async.compose(mul3, add1);\n\nadd1mul3(4, function (err, result) {\n // result now equals 15\n});\n```\n\n---------------------------------------\n\n### applyEach(fns, args..., callback)\n\nApplies the provided arguments to each function in the array, calling the\ncallback after all functions have completed. If you only provide the first\nargument then it will return a function which lets you pass in the\narguments as if it were a single function call.\n\n__Arguments__\n\n* fns - the asynchronous functions to all call with the same arguments\n* args... - any number of separate arguments to pass to the function\n* callback - the final argument should be the callback, called when all\n functions have completed processing\n\n\n__Example__\n\n```js\nasync.applyEach([enableSearch, updateSchema], 'bucket', callback);\n\n// partial application example:\nasync.each(\n buckets,\n async.applyEach([enableSearch, updateSchema]),\n callback\n);\n```\n\n---------------------------------------\n\n\n### applyEachSeries(arr, iterator, callback)\n\nThe same as applyEach only the functions are applied in series.\n\n---------------------------------------\n\n\n### queue(worker, concurrency)\n\nCreates a queue object with the specified concurrency. Tasks added to the\nqueue will be processed in parallel (up to the concurrency limit). If all\nworkers are in progress, the task is queued until one is available. Once\na worker has completed a task, the task's callback is called.\n\n__Arguments__\n\n* worker(task, callback) - An asynchronous function for processing a queued\n task, which must call its callback(err) argument when finished, with an \n optional error as an argument.\n* concurrency - An integer for determining how many worker functions should be\n run in parallel.\n\n__Queue objects__\n\nThe queue object returned by this function has the following properties and\nmethods:\n\n* length() - a function returning the number of items waiting to be processed.\n* concurrency - an integer for determining how many worker functions should be\n run in parallel. This property can be changed after a queue is created to\n alter the concurrency on-the-fly.\n* push(task, [callback]) - add a new task to the queue, the callback is called\n once the worker has finished processing the task.\n instead of a single task, an array of tasks can be submitted. the respective callback is used for every task in the list.\n* unshift(task, [callback]) - add a new task to the front of the queue.\n* saturated - a callback that is called when the queue length hits the concurrency and further tasks will be queued\n* empty - a callback that is called when the last item from the queue is given to a worker\n* drain - a callback that is called when the last item from the queue has returned from the worker\n\n__Example__\n\n```js\n// create a queue object with concurrency 2\n\nvar q = async.queue(function (task, callback) {\n console.log('hello ' + task.name);\n callback();\n}, 2);\n\n\n// assign a callback\nq.drain = function() {\n console.log('all items have been processed');\n}\n\n// add some items to the queue\n\nq.push({name: 'foo'}, function (err) {\n console.log('finished processing foo');\n});\nq.push({name: 'bar'}, function (err) {\n console.log('finished processing bar');\n});\n\n// add some items to the queue (batch-wise)\n\nq.push([{name: 'baz'},{name: 'bay'},{name: 'bax'}], function (err) {\n console.log('finished processing bar');\n});\n\n// add some items to the front of the queue\n\nq.unshift({name: 'bar'}, function (err) {\n console.log('finished processing bar');\n});\n```\n\n---------------------------------------\n\n\n### cargo(worker, [payload])\n\nCreates a cargo object with the specified payload. Tasks added to the\ncargo will be processed altogether (up to the payload limit). If the\nworker is in progress, the task is queued until it is available. Once\nthe worker has completed some tasks, each callback of those tasks is called.\n\n__Arguments__\n\n* worker(tasks, callback) - An asynchronous function for processing an array of\n queued tasks, which must call its callback(err) argument when finished, with \n an optional error as an argument.\n* payload - An optional integer for determining how many tasks should be\n processed per round; if omitted, the default is unlimited.\n\n__Cargo objects__\n\nThe cargo object returned by this function has the following properties and\nmethods:\n\n* length() - a function returning the number of items waiting to be processed.\n* payload - an integer for determining how many tasks should be\n process per round. This property can be changed after a cargo is created to\n alter the payload on-the-fly.\n* push(task, [callback]) - add a new task to the queue, the callback is called\n once the worker has finished processing the task.\n instead of a single task, an array of tasks can be submitted. the respective callback is used for every task in the list.\n* saturated - a callback that is called when the queue length hits the concurrency and further tasks will be queued\n* empty - a callback that is called when the last item from the queue is given to a worker\n* drain - a callback that is called when the last item from the queue has returned from the worker\n\n__Example__\n\n```js\n// create a cargo object with payload 2\n\nvar cargo = async.cargo(function (tasks, callback) {\n for(var i=0; i\n### auto(tasks, [callback])\n\nDetermines the best order for running functions based on their requirements.\nEach function can optionally depend on other functions being completed first,\nand each function is run as soon as its requirements are satisfied. If any of\nthe functions pass an error to their callback, that function will not complete\n(so any other functions depending on it will not run) and the main callback\nwill be called immediately with the error. Functions also receive an object\ncontaining the results of functions which have completed so far.\n\nNote, all functions are called with a results object as a second argument, \nso it is unsafe to pass functions in the tasks object which cannot handle the\nextra argument. For example, this snippet of code:\n\n```js\nasync.auto({\n readData: async.apply(fs.readFile, 'data.txt', 'utf-8')\n}, callback);\n```\n\nwill have the effect of calling readFile with the results object as the last\nargument, which will fail:\n\n```js\nfs.readFile('data.txt', 'utf-8', cb, {});\n```\n\nInstead, wrap the call to readFile in a function which does not forward the \nresults object:\n\n```js\nasync.auto({\n readData: function(cb, results){\n fs.readFile('data.txt', 'utf-8', cb);\n }\n}, callback);\n```\n\n__Arguments__\n\n* tasks - An object literal containing named functions or an array of\n requirements, with the function itself the last item in the array. The key\n used for each function or array is used when specifying requirements. The \n function receives two arguments: (1) a callback(err, result) which must be \n called when finished, passing an error (which can be null) and the result of \n the function's execution, and (2) a results object, containing the results of\n the previously executed functions.\n* callback(err, results) - An optional callback which is called when all the\n tasks have been completed. The callback will receive an error as an argument\n if any tasks pass an error to their callback. Results will always be passed\n\tbut if an error occurred, no other tasks will be performed, and the results\n\tobject will only contain partial results.\n \n\n__Example__\n\n```js\nasync.auto({\n get_data: function(callback){\n // async code to get some data\n },\n make_folder: function(callback){\n // async code to create a directory to store a file in\n // this is run at the same time as getting the data\n },\n write_file: ['get_data', 'make_folder', function(callback){\n // once there is some data and the directory exists,\n // write the data to a file in the directory\n callback(null, filename);\n }],\n email_link: ['write_file', function(callback, results){\n // once the file is written let's email a link to it...\n // results.write_file contains the filename returned by write_file.\n }]\n});\n```\n\nThis is a fairly trivial example, but to do this using the basic parallel and\nseries functions would look like this:\n\n```js\nasync.parallel([\n function(callback){\n // async code to get some data\n },\n function(callback){\n // async code to create a directory to store a file in\n // this is run at the same time as getting the data\n }\n],\nfunction(err, results){\n async.series([\n function(callback){\n // once there is some data and the directory exists,\n // write the data to a file in the directory\n },\n function(callback){\n // once the file is written let's email a link to it...\n }\n ]);\n});\n```\n\nFor a complicated series of async tasks using the auto function makes adding\nnew tasks much easier and makes the code more readable.\n\n\n---------------------------------------\n\n\n### iterator(tasks)\n\nCreates an iterator function which calls the next function in the array,\nreturning a continuation to call the next one after that. It's also possible to\n'peek' the next iterator by doing iterator.next().\n\nThis function is used internally by the async module but can be useful when\nyou want to manually control the flow of functions in series.\n\n__Arguments__\n\n* tasks - An array of functions to run.\n\n__Example__\n\n```js\nvar iterator = async.iterator([\n function(){ sys.p('one'); },\n function(){ sys.p('two'); },\n function(){ sys.p('three'); }\n]);\n\nnode> var iterator2 = iterator();\n'one'\nnode> var iterator3 = iterator2();\n'two'\nnode> iterator3();\n'three'\nnode> var nextfn = iterator2.next();\nnode> nextfn();\n'three'\n```\n\n---------------------------------------\n\n\n### apply(function, arguments..)\n\nCreates a continuation function with some arguments already applied, a useful\nshorthand when combined with other control flow functions. Any arguments\npassed to the returned function are added to the arguments originally passed\nto apply.\n\n__Arguments__\n\n* function - The function you want to eventually apply all arguments to.\n* arguments... - Any number of arguments to automatically apply when the\n continuation is called.\n\n__Example__\n\n```js\n// using apply\n\nasync.parallel([\n async.apply(fs.writeFile, 'testfile1', 'test1'),\n async.apply(fs.writeFile, 'testfile2', 'test2'),\n]);\n\n\n// the same process without using apply\n\nasync.parallel([\n function(callback){\n fs.writeFile('testfile1', 'test1', callback);\n },\n function(callback){\n fs.writeFile('testfile2', 'test2', callback);\n }\n]);\n```\n\nIt's possible to pass any number of additional arguments when calling the\ncontinuation:\n\n```js\nnode> var fn = async.apply(sys.puts, 'one');\nnode> fn('two', 'three');\none\ntwo\nthree\n```\n\n---------------------------------------\n\n\n### nextTick(callback)\n\nCalls the callback on a later loop around the event loop. In node.js this just\ncalls process.nextTick, in the browser it falls back to setImmediate(callback)\nif available, otherwise setTimeout(callback, 0), which means other higher priority\nevents may precede the execution of the callback.\n\nThis is used internally for browser-compatibility purposes.\n\n__Arguments__\n\n* callback - The function to call on a later loop around the event loop.\n\n__Example__\n\n```js\nvar call_order = [];\nasync.nextTick(function(){\n call_order.push('two');\n // call_order now equals ['one','two']\n});\ncall_order.push('one')\n```\n\n\n### times(n, callback)\n\nCalls the callback n times and accumulates results in the same manner\nyou would use with async.map.\n\n__Arguments__\n\n* n - The number of times to run the function.\n* callback - The function to call n times.\n\n__Example__\n\n```js\n// Pretend this is some complicated async factory\nvar createUser = function(id, callback) {\n callback(null, {\n id: 'user' + id\n })\n}\n// generate 5 users\nasync.times(5, function(n, next){\n createUser(n, function(err, user) {\n next(err, user)\n })\n}, function(err, users) {\n // we should now have 5 users\n});\n```\n\n\n### timesSeries(n, callback)\n\nThe same as times only the iterator is applied to each item in the array in\nseries. The next iterator is only called once the current one has completed\nprocessing. The results array will be in the same order as the original.\n\n\n## Utils\n\n\n### memoize(fn, [hasher])\n\nCaches the results of an async function. When creating a hash to store function\nresults against, the callback is omitted from the hash and an optional hash\nfunction can be used.\n\nThe cache of results is exposed as the `memo` property of the function returned\nby `memoize`.\n\n__Arguments__\n\n* fn - the function you to proxy and cache results from.\n* hasher - an optional function for generating a custom hash for storing\n results, it has all the arguments applied to it apart from the callback, and\n must be synchronous.\n\n__Example__\n\n```js\nvar slow_fn = function (name, callback) {\n // do something\n callback(null, result);\n};\nvar fn = async.memoize(slow_fn);\n\n// fn can now be used as if it were slow_fn\nfn('some name', function () {\n // callback\n});\n```\n\n\n### unmemoize(fn)\n\nUndoes a memoized function, reverting it to the original, unmemoized\nform. Comes handy in tests.\n\n__Arguments__\n\n* fn - the memoized function\n\n\n### log(function, arguments)\n\nLogs the result of an async function to the console. Only works in node.js or\nin browsers that support console.log and console.error (such as FF and Chrome).\nIf multiple arguments are returned from the async function, console.log is\ncalled on each argument in order.\n\n__Arguments__\n\n* function - The function you want to eventually apply all arguments to.\n* arguments... - Any number of arguments to apply to the function.\n\n__Example__\n\n```js\nvar hello = function(name, callback){\n setTimeout(function(){\n callback(null, 'hello ' + name);\n }, 1000);\n};\n```\n```js\nnode> async.log(hello, 'world');\n'hello world'\n```\n\n---------------------------------------\n\n\n### dir(function, arguments)\n\nLogs the result of an async function to the console using console.dir to\ndisplay the properties of the resulting object. Only works in node.js or\nin browsers that support console.dir and console.error (such as FF and Chrome).\nIf multiple arguments are returned from the async function, console.dir is\ncalled on each argument in order.\n\n__Arguments__\n\n* function - The function you want to eventually apply all arguments to.\n* arguments... - Any number of arguments to apply to the function.\n\n__Example__\n\n```js\nvar hello = function(name, callback){\n setTimeout(function(){\n callback(null, {hello: name});\n }, 1000);\n};\n```\n```js\nnode> async.dir(hello, 'world');\n{hello: 'world'}\n```\n\n---------------------------------------\n\n\n### noConflict()\n\nChanges the value of async back to its original value, returning a reference to the\nasync object.\n", + "readmeFilename": "README.md", + "_id": "async@0.2.10", + "_from": "async@~0.2.9" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/.npmignore b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/.npmignore new file mode 100644 index 0000000..aba34f0 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/.npmignore @@ -0,0 +1,3 @@ +*.un~ +/node_modules +/test/tmp diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/License b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/License new file mode 100644 index 0000000..4804b7a --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/form-data/node_modules/combined-stream/License @@ -0,0 +1,19 @@ +Copyright (c) 2011 Debuggable Limited + +Permission is hereby granted, free of charge, to any person obtaining a copy +of this software and associated documentation files (the "Software"), to deal +in the Software without restriction, including without limitation the rights +to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +copies of the Software, and to permit persons to whom the Software is +furnished to do so, subject to the following conditions: + +The above copyright notice and this permission notice shall be included in +all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

If you don't want that to happen, you can set `pauseStreams`\nto `false`:\n\n``` javascript\nvar CombinedStream = require('combined-stream');\nvar fs = require('fs');\n\nvar combinedStream = CombinedStream.create({pauseStreams: false});\ncombinedStream.append(fs.createReadStream('file1.txt'));\ncombinedStream.append(fs.createReadStream('file2.txt'));\n\ncombinedStream.pipe(fs.createWriteStream('combined.txt'));\n```\n\nHowever, what if you don't have all the source streams yet, or you don't want\nto allocate the resources (file descriptors, memory, etc.) for them right away?\nWell, in that case you can simply provide a callback that supplies the stream\nby calling a `next()` function:\n\n``` javascript\nvar CombinedStream = require('combined-stream');\nvar fs = require('fs');\n\nvar combinedStream = CombinedStream.create();\ncombinedStream.append(function(next) {\n next(fs.createReadStream('file1.txt'));\n});\ncombinedStream.append(function(next) {\n next(fs.createReadStream('file2.txt'));\n});\n\ncombinedStream.pipe(fs.createWriteStream('combined.txt'));\n```\n\n## API\n\n### CombinedStream.create([options])\n\nReturns a new combined stream object. Available options are:\n\n* `maxDataSize`\n* `pauseStreams`\n\nThe effect of those options is described below.\n\n### combinedStream.pauseStreams = true\n\nWhether to apply back pressure to the underlaying streams. If set to `false`,\nthe underlaying streams will never be paused. If set to `true`, the\nunderlaying streams will be paused right after being appended, as well as when\n`delayedStream.pipe()` wants to throttle.\n\n### combinedStream.maxDataSize = 2 * 1024 * 1024\n\nThe maximum amount of bytes (or characters) to buffer for all source streams.\nIf this value is exceeded, `combinedStream` emits an `'error'` event.\n\n### combinedStream.dataSize = 0\n\nThe amount of bytes (or characters) currently buffered by `combinedStream`.\n\n### combinedStream.append(stream)\n\nAppends the given `stream` to the combinedStream object. If `pauseStreams` is\nset to `true, this stream will also be paused right away.\n\n`streams` can also be a function that takes one parameter called `next`. `next`\nis a function that must be invoked in order to provide the `next` stream, see\nexample above.\n\nRegardless of how the `stream` is appended, combined-stream always attaches an\n`'error'` listener to it, so you don't have to do that manually.\n\nSpecial case: `stream` can also be a String or Buffer.\n\n### combinedStream.write(data)\n\nYou should not call this, `combinedStream` takes care of piping the appended\nstreams into itself for you.\n\n### combinedStream.resume()\n\nCauses `combinedStream` to start drain the streams it manages. The function is\nidempotent, and also emits a `'resume'` event each time which usually goes to\nthe stream that is currently being drained.\n\n### combinedStream.pause();\n\nIf `combinedStream.pauseStreams` is set to `false`, this does nothing.\nOtherwise a `'pause'` event is emitted, this goes to the stream that is\ncurrently being drained, so you can use it to apply back pressure.\n\n### combinedStream.end();\n\nSets `combinedStream.writable` to false, emits an `'end'` event, and removes\nall streams from the queue.\n\n### combinedStream.destroy();\n\nSame as `combinedStream.end()`, except it emits a `'close'` event instead of\n`'end'`.\n\n## License\n\ncombined-stream is licensed under the MIT license.\n", + "readmeFilename": "Readme.md", + "bugs": { +

Can be used to submit forms and file uploads to other web applications.\n\nThe API of this module is inspired by the [XMLHttpRequest-2 FormData Interface][xhr2-fd].\n\n[xhr2-fd]: http://dev.w3.org/2006/webapi/XMLHttpRequest-2/Overview.html#the-formdata-interface\n[streams2-thing]: http://nodejs.org/api/stream.html#stream_compatibility_with_older_node_versions\n\n## Install\n\n```\nnpm install form-data\n```\n\n## Usage\n\nIn this example we are constructing a form with 3 fields that contain a string,\na buffer and a file stream.\n\n``` javascript\nvar FormData = require('form-data');\nvar fs = require('fs');\n\nvar form = new FormData();\nform.append('my_field', 'my value');\nform.append('my_buffer', new Buffer(10));\nform.append('my_file', fs.createReadStream('/foo/bar.jpg'));\n```\n\nAlso you can use http-response stream:\n\n``` javascript\nvar FormData = require('form-data');\nvar http = require('http');\n\nvar form = new FormData();\n\nhttp.request('http://nodejs.org/images/logo.png', function(response) {\n form.append('my_field', 'my value');\n form.append('my_buffer', new Buffer(10));\n form.append('my_logo', response);\n});\n```\n\nOr @mikeal's request stream:\n\n``` javascript\nvar FormData = require('form-data');\nvar request = require('request');\n\nvar form = new FormData();\n\nform.append('my_field', 'my value');\nform.append('my_buffer', new Buffer(10));\nform.append('my_logo', request('http://nodejs.org/images/logo.png'));\n```\n\nIn order to submit this form to a web application, call ```submit(url, [callback])``` method:\n\n``` javascript\nform.submit('http://example.org/', function(err, res) {\n // res – response object (http.IncomingMessage) //\n res.resume(); // for node-0.10.x\n});\n\n```\n\nFor more advanced request manipulations ```submit()``` method returns ```http.ClientRequest``` object, or you can choose from one of the alternative submission methods.\n\n### Alternative submission methods\n\nYou can use node's http client interface:\n\n``` javascript\nvar http = require('http');\n\nvar request = http.request({\n method: 'post',\n host: 'example.org',\n path: '/upload',\n headers: form.getHeaders()\n});\n\nform.pipe(request);\n\nrequest.on('response', function(res) {\n console.log(res.statusCode);\n});\n```\n\nOr if you would prefer the `'Content-Length'` header to be set for you:\n\n``` javascript\nform.submit('example.org/upload', function(err, res) {\n console.log(res.statusCode);\n});\n```\n\nTo use custom headers and pre-known length in parts:\n\n``` javascript\nvar CRLF = '\\r\\n';\nvar form = new FormData();\n\nvar options = {\n header: CRLF + '--' + form.getBoundary() + CRLF + 'X-Custom-Header: 123' + CRLF + CRLF,\n knownLength: 1\n};\n\nform.append('my_buffer', buffer, options);\n\nform.submit('http://example.com/', function(err, res) {\n if (err) throw err;\n console.log('Done');\n});\n```\n\nForm-Data can recognize and fetch all the required information from common types of streams (```fs.readStream```, ```http.response``` and ```mikeal's request```), for some other types of streams you'd need to provide \"file\"-related information manually:\n\n``` javascript\nsomeModule.stream(function(err, stdout, stderr) {\n if (err) throw err;\n\n var form = new FormData();\n\n form.append('file', stdout, {\n filename: 'unicycle.jpg',\n contentType: 'image/jpg',\n knownLength: 19806\n });\n\n form.submit('http://example.com/', function(err, res) {\n if (err) throw err;\n console.log('Done');\n });\n});\n```\n\nFor edge cases, like POST request to URL with query string or to pass HTTP auth credentials, object can be passed to `form.submit()` as first parameter:\n\n``` javascript\nform.submit({\n host: 'example.com',\n path: '/probably.php?extra=params',\n auth: 'username:password'\n}, function(err, res) {\n console.log(res.statusCode);\n});\n```\n\n## Notes\n\n- ```getLengthSync()``` method DOESN'T calculate length for streams, use ```knownLength``` options as workaround.\n- If it feels like FormData hangs after submit and you're on ```node-0.10```, please check [Compatibility with Older Node Versions][streams2-thing]\n\n## TODO\n\n- Add new streams (0.10) support and try really hard not to break it for 0.8.x.\n\n## License\n\nForm-Data is licensed

    +- [**Frequently Asked Questions**](#frequently-asked-questions) +

    +- [**Acknowledgements**](#acknowledgements) + +# Introduction + +**Hawk** is an HTTP authentication scheme providing mechanisms for making authenticated HTTP requests with +partial cryptographic verification of the request and response, covering the HTTP method, request URI, host, +and optionally the request payload. + +Similar to the HTTP [Digest access authentication schemes](http://www.ietf.org/rfc/rfc2617.txt), **Hawk** uses a set of +client credentials which include an identifier (e.g. username) and key (e.g. password). Likewise, just as with the Digest scheme, +the key is never included in authenticated requests. Instead, it is used to calculate a request MAC value which is +included in its place. + +However, **Hawk** has several differences from Digest. In particular, while both use a nonce to limit the possibility of +replay attacks, in **Hawk** the client generates the nonce and uses it in combination with a timestamp, leading to less +"chattiness" (interaction with the server). + +Also unlike Digest, this scheme is not intended to protect the key itself (the password in Digest) because +the client and server must both have access to the key material in the clear. + +The primary design goals of this scheme are to: +* simplify and improve HTTP authentication for services that are unwilling or unable to deploy TLS for all resources, +* secure credentials against leakage (e.g., when the client uses some form of dynamic configuration to determine where + to send an authenticated request), and +* avoid the exposure of credentials sent to a malicious server over an unauthenticated secure channel due to client + failure to validate the server's identity as part of its TLS handshake. + +In addition, **Hawk** supports a method for granting third-parties temporary access to individual resources using +a query parameter called _bewit_ (in falconry, a leather strap used to attach a tracking device to the leg of a hawk). + +The **Hawk** scheme requires the establishment of a shared symmetric key between the client and the server, +which is beyond the scope of this module. Typically, the shared credentials are established via an initial +TLS-protected phase or derived from some other shared confidential information available to both the client +and the server. + + +## Replay Protection + +Without replay protection, an attacker can use a compromised (but otherwise valid and authenticated) request more +than once, gaining access to a protected resource. To mitigate this, clients include both a nonce and a timestamp when +making requests. This gives the server enough information to prevent replay attacks. + +The nonce is generated by the client, and is a string unique across all requests with the same timestamp and +key identifier combination. + +The timestamp enables the server to restrict the validity period of the credentials where requests occuring afterwards +are rejected. It also removes the need for the server to retain an unbounded number of nonce values for future checks. +By default, **Hawk** uses a time window of 1 minute to allow for time skew between the client and server (which in +practice translates to a maximum of 2 minutes as the skew can be positive or negative). + +Using a timestamp requires the client's clock to be in sync with the server's clock. **Hawk** requires both the client +clock and the server clock to use NTP to ensure synchronization. However, given the limitations of some client types +(e.g. browsers) to deploy NTP, the server provides the client with its current time (in seconds precision) in response +to a bad timestamp. + +There is no expectation that the client will adjust its system clock to match the server (in fact, this would be a +potential attack vector). Instead, the client only uses the server's time to calculate an offset used only +for communications with that particular server. The protocol rewards clients with synchronized clocks by reducing +the number of round trips required to authenticate the first request. + + +## Usage Example + +Server code: + +```javascript +var Http = require('http'); +var Hawk = require('hawk'); + + +// Credentials lookup function + +var credentialsFunc = function (id, callback) { + + var credentials = { + key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', + algorithm: 'sha256', + user: 'Steve' + }; + + return callback(null, credentials); +}; + +// Create HTTP server + +var handler = function (req, res) { + + // Authenticate incoming request + + Hawk.server.authenticate(req, credentialsFunc, {}, function (err, credentials, artifacts) { + + // Prepare response + + var payload = (!err ? 'Hello ' + credentials.user + ' ' + artifacts.ext : 'Shoosh!'); + var headers = { 'Content-Type': 'text/plain' }; + + // Generate Server-Authorization response header + + var header = Hawk.server.header(credentials, artifacts, { payload: payload, contentType: headers['Content-Type'] }); + headers['Server-Authorization'] = header; + + // Send the response back + + res.writeHead(!err ? 200 : 401, headers); + res.end(payload); + }); +}; + +// Start server + +Http.createServer(handler).listen(8000, 'example.com'); +``` + +Client code: + +```javascript +var Request = require('request'); +var Hawk = require('hawk'); + + +// Client credentials + +var credentials = { + id: 'dh37fgj492je', + key: 'werxhqb98rpaxn39848xrunpaw3489ruxnpa98w4rxn', + algorithm: 'sha256' +} + +// Request options + +var requestOptions = { + uri: 'http://example.com:8000/resource/1?b=1&a=2', + method: 'GET', + headers: {} +}; + +// Generate Authorization request header + +var header = Hawk.client.header('http://example.com:8000/resource/1?b=1&a=2', 'GET', { credentials: credentials, ext: 'some-app-data' }); +requestOptions.headers.Authorization = header.field; + +// Send authenticated request + +Request(requestOptions, function (error, response, body) { + + // Authenticate the server's response + + var isValid = Hawk.client.authenticate(response, credentials, header.artifacts, { payload: body }); + + // Output results + + console.log(response.statusCode + ': ' + body + (isValid ?

If the MAC is valid, the server calculates the payload hash and compares the value +with the provided payload hash in the header. In many cases, checking the MAC first is faster than calculating the payload hash. + +However, if the payload is not available at authentication time (e.g. too large to fit in memory, streamed elsewhere, or processed +at a different stage in the application), the server may choose to defer payload validation for later by retaining the hash value +provided by the client after validating the MAC. + +It is important to note that MAC validation does not mean the hash value provided by the client is valid, only that the value +included in the header was not modified. Without calculating the payload hash on the server and comparing it to the value provided +by the client, the payload may be modified by an attacker. + + +## Response Payload Validation + +**Hawk** provides partial response payload validation. The server includes the `Server-Authorization` response header which enables the +client to authenticate the response and ensure it is talking to the right server. **Hawk** defines the HTTP `Server-Authorization` header +as a response header using the exact same syntax as the `Authorization` request header field. + +The header is contructed using the same process as the client's request header. The server uses the same credentials and other +artifacts provided by the client to constructs the normalized request string. The `ext` and `hash` values are replaced with +new values based on the server response. The rest as identical to those used by the client. + +The result MAC digest is included with the optional `hash` and `ext` values: + +``` +Server-Authorization: Hawk mac="XIJRsMl/4oL+nn+vKoeVZPdCHXB4yJkNnBbTbHFZUYE=", hash="f9cDF/TDm7TkYRLnGwRMfeDzT6LixQVLvrIKhh0vgmM=", ext="response-specific" +``` + + +## Browser Support and Considerations + +A browser script is provided for including using a `')); + expect(boom.response.payload.message).to.not.contain(''); + expect(encoded).to.equal('\\x3cscript\\x3ealert\\x281\\x29\\x3c\\x2fscript\\x3e'); + done(); + }); + + it('encodes \' characters', function (done) { + + var encoded = Hoek.escapeJavaScript('something(\'param\')'); + expect(encoded).to.equal('something\\x28\\x27param\\x27\\x29'); + done(); + }); + + it('encodes large unicode characters with the correct padding', function (done) { + + var encoded = Hoek.escapeJavaScript(String.fromCharCode(500) + String.fromCharCode(1000)); + expect(encoded).to.equal('\\u0500\\u1000'); + done(); + }); + + it('doesn\'t throw an exception when passed null', function (done) { + + var encoded = Hoek.escapeJavaScript(null); + expect(encoded).to.equal(''); + done(); + }); + }); + + describe('#escapeHtml', function () { + + it('encodes / characters', function (done) { + + var encoded = Hoek.escapeHtml(''); + expect(encoded).to.equal('<script>alert(1)</script>'); + done(); + }); + + it('encodes < and > as named characters', function (done) { + + var encoded = Hoek.escapeHtml(' +``` + +Or in node.js: + +``` +npm install node-uuid +``` + +```javascript +var uuid = require('node-uuid'); +``` + +Then create some ids ... + +```javascript +// Generate a v1 (time-based) id +uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a' + +// Generate a v4 (random) id +uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1' +``` + +## API + +### uuid.v1([`options` [, `buffer` [, `offset`]]]) + +Generate and return a RFC4122 v1 (timestamp-based) UUID. + +* `options` - (Object) Optional uuid state to apply.

Generate RFC4122 version 1 or version 4 UUIDs\n* Runs in node.js and all browsers.\n* Registered as a [ComponentJS](https://github.com/component/component) [component](https://github.com/component/component/wiki/Components) ('broofa/node-uuid').\n* Cryptographically strong random # generation on supporting platforms\n* 1.1K minified and gzip'ed (Want something smaller? Check this [crazy shit](https://gist.github.com/982883) out! )\n* [Annotated source code](http://broofa.github.com/node-uuid/docs/uuid.html)\n\n## Getting Started\n\nInstall it in your browser:\n\n```html\n\n```\n\nOr in node.js:\n\n```\nnpm install node-uuid\n```\n\n```javascript\nvar uuid = require('node-uuid');\n```\n\nThen create some ids ...\n\n```javascript\n// Generate a v1 (time-based) id\nuuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'\n\n// Generate a v4 (random) id\nuuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'\n```\n\n## API\n\n### uuid.v1([`options` [, `buffer` [, `offset`]]])\n\nGenerate and return a RFC4122 v1 (timestamp-based) UUID.\n\n* `options` - (Object) Optional uuid state to apply. Properties may include:\n\n * `node` - (Array) Node id as Array of 6 bytes (per 4.1.6). Default: Randomly generated ID. See note 1.\n * `clockseq` - (Number between 0 - 0x3fff) RFC clock sequence. Default: An internally maintained clockseq is used.\n * `msecs` - (Number | Date) Time in milliseconds since unix Epoch. Default: The current time is used.\n * `nsecs` - (Number between 0-9999) additional time, in 100-nanosecond units. Ignored if `msecs` is unspecified. Default: internal uuid counter is used, as per 4.2.1.2.\n\n* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.\n* `offset` - (Number) Starting index in `buffer` at which to begin writing.\n\nReturns `buffer`, if specified, otherwise the string form of the UUID\n\nNotes:\n\n1. The randomly generated node id is only guaranteed to stay constant for the lifetime of the current JS runtime. (Future versions of this module may use persistent storage mechanisms to extend this guarantee.)\n\nExample: Generate string UUID with fully-specified options\n\n```javascript\nuuid.v1({\n node: [0x01, 0x23, 0x45, 0x67, 0x89, 0xab],\n clockseq: 0x1234,\n msecs: new Date('2011-11-01').getTime(),\n nsecs: 5678\n}); // -> \"710b962e-041c-11e1-9234-0123456789ab\"\n```\n\nExample: In-place generation of two binary IDs\n\n```javascript\n// Generate two ids in an array\nvar arr = new Array(32); // -> []\nuuid.v1(null, arr, 0); // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15]\nuuid.v1(null, arr, 16); // -> [02 a2 ce 90 14 32 11 e1 85 58 0b 48 8e 4f c1 15 02 a3 1c b0 14 32 11 e1 85 58 0b 48 8e 4f c1 15]\n\n// Optionally use uuid.unparse() to get stringify the ids\nuuid.unparse(buffer); // -> '02a2ce90-1432-11e1-8558-0b488e4fc115'\nuuid.unparse(buffer, 16) // -> '02a31cb0-1432-11e1-8558-0b488e4fc115'\n```\n\n### uuid.v4([`options` [, `buffer` [, `offset`]]])\n\nGenerate and return a RFC4122 v4 UUID.\n\n* `options` - (Object) Optional uuid state to apply. Properties may include:\n\n * `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values\n * `rng` - (Function) Random # generator to use. Set to one of the built-in generators - `uuid.mathRNG` (all platforms), `uuid.nodeRNG` (node.js only), `uuid.whatwgRNG` (WebKit only) - or a custom function that returns an array[16] of byte values.\n\n* `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.\n* `offset` - (Number) Starting index in `buffer` at which to begin writing.\n\nReturns `buffer`, if specified, otherwise the string form of the UUID\n\nExample: Generate string UUID with fully-specified options\n\n```javascript\nuuid.v4({\n random: [\n 0x10, 0x91, 0x56, 0xbe, 0xc4, 0xfb, 0xc1, 0xea,\n 0x71, 0xb4, 0xef, 0xe1, 0x67, 0x1c, 0x58, 0x36\n ]\n});\n// -> \"109156be-c4fb-41ea-b1b4-efe1671c5836\"\n```\n\nExample: Generate two IDs in a single buffer\n\n```javascript\nvar buffer = new Array(32); // (or 'new Buffer' in node.js)\nuuid.v4(null, buffer, 0);\nuuid.v4(null, buffer, 16);\n```\n\n### uuid.parse(id[, buffer[, offset]])\n### uuid.unparse(buffer[, offset])\n\nParse and unparse UUIDs\n\n * `id` - (String) UUID(-like) string\n * `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written. Default: A new Array or Buffer is used\n * `offset` - (Number) Starting index in `buffer` at which to begin writing. Default: 0\n\nExample parsing and unparsing a UUID string\n\n```javascript\nvar bytes = uuid.parse('797ff043-11eb-11e1-80d6-510998755d10'); // -> \nvar string = uuid.unparse(bytes); // -> '797ff043-11eb-11e1-80d6-510998755d10'\n```\n\n### uuid.noConflict()\n\n(Browsers only) Set `uuid` property back to it's previous value.\n\nReturns the node-uuid object.\n\nExample:\n\n```javascript\nvar myUuid = uuid.noConflict();\nmyUuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'\n```\n\n## Deprecated APIs\n\nSupport for the following v1.2 APIs is available in v1.3, but is deprecated and will be removed in the next major version.\n\n### uuid([format [, buffer [, offset]]])\n\nuuid() has become uuid.v4(), and the `format` argument is now implicit in the `buffer` argument. (i.e. if you specify a buffer, the format is assumed to be binary).\n\n### uuid.BufferClass\n\nThe class of container created when generating binary uuid data if no buffer argument is specified. This is expected to go away, with no replacement API.\n\n## Testing\n\nIn node.js\n\n```\n> cd test\n> node test.js\n```\n\nIn Browser\n\n```\nopen test/test.html\n```\n\n### Benchmarking\n\nRequires node.js\n\n```\nnpm install uuid uuid-js\nnode benchmark/benchmark.js\n```\n\nFor a more complete discussion of node-uuid performance, please see the `benchmark/README.md` file, and the [benchmark wiki](https://github.com/broofa/node-uuid/wiki/Benchmark)\n\nFor browser performance [checkout the JSPerf tests](http://jsperf.com/node-uuid-performance).\n\n## Release notes\n\n### 1.4.0\n\n* Improved module context detection\n* Removed public RNG functions\n\n### 1.3.2\n\n* Improve tests and handling of v1() options (Issue #24)\n* Expose RNG option to allow for perf testing with different generators\n\n### 1.3.0\n\n* Support for version 1 ids, thanks to [@ctavan](https://github.com/ctavan)!\n* Support for node.js crypto API\n* De-emphasizing performance in favor of a) cryptographic quality PRNGs where available and b) more manageable code\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/broofa/node-uuid/issues" + }, + "_id": "node-uuid@1.4.1", + "_from": "node-uuid@~1.4.0" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/node-uuid/test/compare_v1.js b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/node-uuid/test/compare_v1.js new file mode 100644 index 0000000..05af822 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/node-uuid/test/compare_v1.js @@ -0,0 +1,63 @@ +var assert = require('assert'), + nodeuuid = require('../uuid'), + uuidjs = require('uuid-js'), + libuuid = require('uuid').generate, + util = require('util'), + exec = require('child_process').exec, + os = require('os'); + +// On Mac Os X / macports there's only the ossp-uuid package that provides uuid +// On Linux there's uuid-runtime which provides uuidgen +var uuidCmd = os.type() === 'Darwin' ?

Note that node.js v0.6.2+ bundles punycode by default. + +Why the name? NPM modules `cookie`, `cookies` and `cookiejar` were already taken. + +# API + +tough +===== + +Functions on the module you get from `require('tough-cookie')`. All can be used as pure functions and don't need to be "bound". + +parseDate(string[,strict]) +----------------- + +Parse a cookie date string into a `Date`. Parses according to RFC6265 Section 5.1.1, not `Date.parse()`. If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. "Thu, 01 Jan 1970 00:00:010 GMT" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid). + +formatDate(date) +---------------- + +Format a Date into a RFC1123 string (the RFC6265-recommended format). + +canonicalDomain(str) +-------------------- + +Transforms a domain-name into a canonical domain-name. The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265). For the most part, this function is idempotent (can be run again on its output without ill effects). + +domainMatch(str,domStr[,canonicalize=true]) +------------------------------------------- + +Answers "does this real domain match the domain in a cookie?". The `str` is the "current" domain-name and the `domStr` is the "cookie" domain-name. Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a "suffix match". + +The `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not. + +defaultPath(path) +----------------- + +Given a current request/response path, gives the Path apropriate for storing in a cookie. This is basically the "directory" of a "file" in the path, but is specified by Section 5.1.4 of the RFC. + +The `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.). This is the `.pathname` property of node's `uri.parse()` output. + +pathMatch(reqPath,cookiePath) +----------------------------- + +Answers "does the request-path path-match a given cookie-path?" as per RFC6265 Section 5.1.4. Returns a boolean. + +This is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`. + +parse(header[,strict=false]) +---------------------------- + +alias for `Cookie.parse(header[,strict])` + +fromJSON(string) +---------------- + +alias for `Cookie.fromJSON(string)` + +getPublicSuffix(hostname) +------------------------- + +Returns the public suffix of this hostname. The public suffix is the shortest domain-name upon which a cookie can be set. Returns `null` if the hostname cannot have cookies set for it. + +For example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`. + +For further information, see http://publicsuffix.org/. This module derives its list from that site. + +cookieCompare(a,b) +------------------ + +For use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). Longest `.path`s go first, then sorted oldest to youngest. + +``` javascript +var cookies = [ /* unsorted array of Cookie objects */ ]; +cookies = cookies.sort(cookieCompare); +``` + +permuteDomain(domain) +--------------------- + +Generates a list of all possible domains that `domainMatch()` the parameter. May be handy for implementing cookie stores. + + +permutePath(path) +----------------- + +Generates a list of all possible paths that `pathMatch()` the parameter. May be handy for implementing cookie stores. + +Cookie +====== + +Cookie.parse(header[,strict=false]) +----------------------------------- + +Parses a single Cookie or Set-Cookie HTTP header into a `Cookie` object. Returns `undefined` if the string can't be parsed. If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265. Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off. + +Here's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response: + +``` javascript +if (res.headers['set-cookie'] instanceof Array) + cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); }); +else + cookies = [Cookie.parse(res.headers['set-cookie'])]; +``` + +Cookie.fromJSON(string) +----------------------- + +Convert a JSON string to a `Cookie` object. Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects. + +Properties +========== + + * _key_ - string - the name or key of the cookie (default "") + * _value_ - string - the value of the cookie (default "") + * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `"Infinity"`). See `setExpires()` + * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie. May also be set to strings `"Infinity"` and `"-Infinity"` for non-expiry and immediate-expiry, respectively. See `setMaxAge()` + * _domain_ - string - the `Domain=` attribute of the cookie + * _path_ - string - the `Path=` of the cookie + * _secure_ - boolean - the `Secure` cookie flag + * _httpOnly_ - boolean - the `HttpOnly` cookie flag + * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside) + +After a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes: + + * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied) + * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one. + * _created_ - `Date` - when this cookie was added to the jar + * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented. Using `cookiejar.getCookies(...)` will update this attribute. + +Construction([{options}]) +------------ + +Receives an options object that can contain any Cookie properties, uses the default for unspecified properties. + +.toString() +----------- + +encode to a Set-Cookie header value. The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`. + +.cookieString() +--------------- + +encode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '='). + +.setExpires(String) +------------------- + +sets the expiry based on a date-string passed through `parseDate()`. If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `"Infinity"` (a string) is set. + +.setMaxAge(number) +------------------- + +sets the maxAge in seconds. Coerces `-Infinity` to `"-Infinity"` and `Infinity` to `"Infinity"` so it JSON serializes correctly. + +.expiryTime([now=Date.now()]) +----------------------------- + +.expiryDate([now=Date.now()]) +----------------------------- + +expiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object. Note that in both cases the `now` parameter should be milliseconds. + +Max-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute. + +If Expires (`.expires`) is set, that's returned. + +Otherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for "Tue, 19 Jan 2038 03:14:07 GMT" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents). + +.TTL([now=Date.now()]) +--------- + +compute the TTL relative to `now` (milliseconds). The same precedence rules as for `expiryTime`/`expiryDate` apply. + +The "number" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired. Otherwise a time-to-live in milliseconds is returned. + +.canonicalizedDoman() +--------------------- + +.cdomain() +---------- + +return the canonicalized `.domain` field. This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters. + +.validate() +----------- + +Status: *IN PROGRESS*. Works for a few things, but is by no means comprehensive. + +validates cookie attributes for semantic correctness. Useful for "lint" checking any Set-Cookie headers you generate. For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct: + +``` javascript +if (cookie.validate() === true) { + // it's tasty +} else { + // yuck! +} +``` + +CookieJar +========= + +Construction([store = new MemoryCookieStore()][, rejectPublicSuffixes]) +------------ + +Simply use `new CookieJar()`. If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used. + + +Attributes +---------- + + * _rejectPublicSuffixes_ - boolean - reject cookies with domains like "com" and "co.uk" (default: `true`) + +Since eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods. + +.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie)) +------------------------------------------------------------------- + +Attempt to set the cookie in the cookie jar. If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through. The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties. + +The `options` object can be omitted and can have the following properties: + + * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies. + * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`. + * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies + * _strict_ - boolean - default `false` - perform extra checks + * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains. CookieStore errors aren't ignored by this option. + +As per the RFC, the `.hostOnly` property is set if there was no "Domain=" parameter in the cookie string (or `.domain` was null on the Cookie object). The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case. Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual). + +.setCookieSync(cookieOrString, currentUrl, [{options}]) +------------------------------------------------------- + +Synchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.storeCookie(cookie, [{options},] cb(err,cookie)) +------------------------------------------------- + +__REMOVED__ removed in lieu of the CookieStore API below + +.getCookies(currentUrl, [{options},] cb(err,cookies)) +----------------------------------------------------- + +Retrieve the list of cookies that can be sent in a Cookie header for the current url. + +If an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed. The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given. + +The `options` object can be omitted and can have the following properties: + + * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies. + * _secure_ - boolean - autodetect from url - indicates if this is a "Secure" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`. + * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies + * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store. Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially). + * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it). + +The `.lastAccessed` property of the returned cookies will have been updated. + +.getCookiesSync(currentUrl, [{options}]) +---------------------------------------- + +Synchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.getCookieString(...) +--------------------- + +Accepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback. Simply maps the `Cookie` array via `.cookieString()`. + +.getCookieStringSync(...) +------------------------- + +Synchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +.getSetCookieStrings(...) +------------------------- + +Returns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`. Simply maps the cookie array via `.toString()`. + +.getSetCookieStringsSync(...) +----------------------------- + +Synchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`). + +Store +===== + +Base class for CookieJar stores. + +# CookieStore API + +The storage model for each `CookieJar` instance can be replaced with a custom implementation. The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file. The API uses continuation-passing-style to allow for asynchronous stores. + +Stores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`. Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used. + +All `domain` parameters will have been normalized before calling. + +The Cookie store must have all of the following methods. + +store.findCookie(domain, path, key, cb(err,cookie)) +--------------------------------------------------- + +Retrieve a cookie with the given domain, path and key (a.k.a. name). The RFC maintains that exactly one of these cookies should exist in a store. If the store is using versioning, this means that the latest/newest such cookie should be returned. + +Callback takes an error and the resulting `Cookie` object. If no cookie is found then `null` MUST be passed instead (i.e. not an error). + +store.findCookies(domain, path, cb(err,cookies)) +------------------------------------------------ + +Locates cookies matching the given domain and path. This is most often called in the context of `cookiejar.getCookies()` above. + +If no cookies are found, the callback MUST be passed an empty array. + +The resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method. However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done. + +As of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`. If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only). + +store.putCookie(cookie, cb(err)) +-------------------------------- + +Adds a new cookie to the store. The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur. + +The `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties. + +Pass an error if the cookie cannot be stored. + +store.updateCookie(oldCookie, newCookie, cb(err)) +------------------------------------------------- + +Update an existing cookie. The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`. The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store. + +The `.lastAccessed` property will always be different between the two objects and `.created` will always be the same. Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion). + +Stores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie. If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object. + +The `newCookie` and `oldCookie` objects MUST NOT be modified. + +Pass an error if the newCookie cannot be stored. + +store.removeCookie(domain, path, key, cb(err)) +---------------------------------------------- + +Remove a cookie from the store (see notes on `findCookie` about the uniqueness constraint). + +The implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie. + +store.removeCookies(domain, path, cb(err)) +------------------------------------------ + +Removes matching cookies from the store. The `path` paramter is optional, and if missing means all paths in a domain should be removed. + +Pass an error ONLY if removing any existing cookies failed. + +# TODO + + * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()` + * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891 + * better tests for `validate()`? + +# Copyright and License + +(tl;dr: MIT with some MPL/1.1) + +Copyright 2012- GoInstant, Inc. and other contributors.

Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/LICENSE-MIT.txt b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/LICENSE-MIT.txt new file mode 100644 index 0000000..97067e5 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/LICENSE-MIT.txt @@ -0,0 +1,20 @@ +Copyright Mathias Bynens + +Permission is hereby granted, free of charge, to any person obtaining +a copy of this software and associated documentation files (the +"Software"), to deal in the Software without restriction, including +without limitation the rights to use, copy, modify, merge, publish, +distribute, sublicense, and/or sell copies of the Software, and to +permit persons to whom the Software is furnished to do so, subject to +the following conditions: + +The above copyright notice and this permission notice shall be +included in all copies or substantial portions of the Software. + +THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, +EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF +MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND +NONINFRINGEMENT.

While [JavaScript uses UCS-2 internally](http://mathiasbynens.be/notes/javascript-encoding), this function will convert a pair of surrogate halves (each of which UCS-2 exposes as separate characters) into a single code point, matching UTF-16.\n\n```js\npunycode.ucs2.decode('abc'); // [0x61, 0x62, 0x63]\n// surrogate pair for U+1D306 TETRAGRAM FOR CENTRE:\npunycode.ucs2.decode('\\uD834\\uDF06'); // [0x1D306]\n```\n\n#### `punycode.ucs2.encode(codePoints)`\n\nCreates a string based on an array of numeric code point values.\n\n```js\npunycode.ucs2.encode([0x61, 0x62, 0x63]); // 'abc'\npunycode.ucs2.encode([0x1D306]); // '\\uD834\\uDF06'\n```\n\n### `punycode.version`\n\nA string representing the current Punycode.js version number.\n\n[Full API documentation is available.](https://github.com/bestiejs/punycode.js/tree/master/docs#readme)\n\n## Unit tests & code coverage\n\nAfter cloning this repository, run `npm install --dev` to install the dependencies needed for Punycode.js development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.\n\nOnce that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, PhantomJS, and web browsers as well, use `grunt test`.\n\nTo generate [the code coverage report](http://rawgithub.com/bestiejs/punycode.js/master/coverage/punycode.js/punycode.js.html), use `grunt cover`.\n\nFeel free to fork if you see possible improvements!\n\n## Author\n\n| [![twitter/mathias](http://gravatar.com/avatar/24e08a9ea84deb17ae121074d0f17125?s=70)](http://twitter.com/mathias \"Follow @mathias on Twitter\") |\n|---|\n| [Mathias Bynens](http://mathiasbynens.be/) |\n\n## Contributors\n\n| [![twitter/jdalton](http://gravatar.com/avatar/299a3d891ff1920b69c364d061007043?s=70)](http://twitter.com/jdalton \"Follow @jdalton on Twitter\") |\n|---|\n| [John-David Dalton](http://allyoucanleet.com/) |\n\n## License\n\nPunycode.js is dual licensed under the [MIT](http://mths.be/mit) and [GPL](http://mths.be/gpl) licenses.\n", + "readmeFilename": "README.md", + "_id": "punycode@1.2.4", + "dist": { + "shasum": "54008ac972aec74175def9cba6df7fa9d3918740" + }, + "_from": "punycode@>=0.2.0", + "_resolved": "https://registry.npmjs.org/punycode/-/punycode-1.2.4.tgz" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/punycode.js b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/punycode.js new file mode 100644 index 0000000..d5b9bc2 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/node_modules/tough-cookie/node_modules/punycode/punycode.js @@ -0,0 +1,507 @@ +/*! http://mths.be/punycode v1.2.4 by @mathias */ +;(function(root) { + + /** Detect free variables */ + var freeExports = typeof exports == 'object' && exports; + var freeModule = typeof module == 'object' && module && + module.exports == freeExports && module; + var freeGlobal = typeof global == 'object' && global; + if (freeGlobal.global === freeGlobal || freeGlobal.window === freeGlobal) { + root = freeGlobal; + } + + /** + * The `punycode` object. + * @name punycode + * @type Object + */ + var punycode, + + /** Highest positive signed 32-bit float value */ + maxInt = 2147483647, // aka. 0x7FFFFFFF or 2^31-1 + + /** Bootstring parameters */ + base = 36, + tMin = 1, + tMax = 26, + skew = 38, + damp = 700, + initialBias = 72, + initialN = 128, // 0x80 + delimiter = '-', // '\x2D' + + /** Regular expressions */ + regexPunycode = /^xn--/, + regexNonASCII = /[^ -~]/, // unprintable ASCII chars + non-ASCII chars + regexSeparators = /\x2E|\u3002|\uFF0E|\uFF61/g, // RFC 3490 separators + + /** Error messages */ + errors = { + 'overflow': 'Overflow: input needs wider integers to process', + 'not-basic': 'Illegal input >= 0x80 (not a basic code point)', + 'invalid-input': 'Invalid input' + }, + + /** Convenience shortcuts */ + baseMinusTMin = base - tMin, + floor = Math.floor, + stringFromCharCode = String.fromCharCode, + + /** Temporary variable */ + key; + + /*--------------------------------------------------------------------------*/ + + /** + * A generic error utility function. + * @private + * @param {String} type The error type. + * @returns {Error} Throws a `RangeError` with the applicable error message. + */ + function error(type) { + throw RangeError(errors[type]); + } + + /** + * A generic `Array#map` utility function. + * @private + * @param {Array} array The array to iterate over. + * @param {Function} callback The function that gets called for every array + * item. + * @returns {Array} A new array of values returned by the callback function. + */ + function map(array, fn) { + var length = array.length; + while (length--) { + array[length] = fn(array[length]); + } + return array; + } + + /** + * A simple `Array#map`-like wrapper to work with domain name strings. + * @private + * @param {String} domain The domain name. + * @param {Function} callback The function that gets called for every + * character. + * @returns {Array} A new string of characters returned by the callback + * function. + */ + function mapDomain(string, fn) { + return map(string.split(regexSeparators), fn).join('.'); + } + + /** + * Creates an array containing the numeric code points of each Unicode + * character in the string.

If strict is set to true then leading/trailing non-seperator characters around the time part will cause the parsing to fail (e.g. \"Thu, 01 Jan 1970 00:00:010 GMT\" has an extra trailing zero but Chrome, an assumedly RFC-compliant browser, treats this as valid).\n\nformatDate(date)\n----------------\n\nFormat a Date into a RFC1123 string (the RFC6265-recommended format).\n\ncanonicalDomain(str)\n--------------------\n\nTransforms a domain-name into a canonical domain-name. The canonical domain-name is a trimmed, lowercased, stripped-of-leading-dot and optionally punycode-encoded domain-name (Section 5.1.2 of RFC6265). For the most part, this function is idempotent (can be run again on its output without ill effects).\n\ndomainMatch(str,domStr[,canonicalize=true])\n-------------------------------------------\n\nAnswers \"does this real domain match the domain in a cookie?\". The `str` is the \"current\" domain-name and the `domStr` is the \"cookie\" domain-name. Matches according to RFC6265 Section 5.1.3, but it helps to think of it as a \"suffix match\".\n\nThe `canonicalize` parameter will run the other two paramters through `canonicalDomain` or not.\n\ndefaultPath(path)\n-----------------\n\nGiven a current request/response path, gives the Path apropriate for storing in a cookie. This is basically the \"directory\" of a \"file\" in the path, but is specified by Section 5.1.4 of the RFC.\n\nThe `path` parameter MUST be _only_ the pathname part of a URI (i.e. excludes the hostname, query, fragment, etc.). This is the `.pathname` property of node's `uri.parse()` output.\n\npathMatch(reqPath,cookiePath)\n-----------------------------\n\nAnswers \"does the request-path path-match a given cookie-path?\" as per RFC6265 Section 5.1.4. Returns a boolean.\n\nThis is essentially a prefix-match where `cookiePath` is a prefix of `reqPath`.\n\nparse(header[,strict=false])\n----------------------------\n\nalias for `Cookie.parse(header[,strict])`\n\nfromJSON(string)\n----------------\n\nalias for `Cookie.fromJSON(string)`\n\ngetPublicSuffix(hostname)\n-------------------------\n\nReturns the public suffix of this hostname. The public suffix is the shortest domain-name upon which a cookie can be set. Returns `null` if the hostname cannot have cookies set for it.\n\nFor example: `www.example.com` and `www.subdomain.example.com` both have public suffix `example.com`.\n\nFor further information, see http://publicsuffix.org/. This module derives its list from that site.\n\ncookieCompare(a,b)\n------------------\n\nFor use with `.sort()`, sorts a list of cookies into the recommended order given in the RFC (Section 5.4 step 2). Longest `.path`s go first, then sorted oldest to youngest.\n\n``` javascript\nvar cookies = [ /* unsorted array of Cookie objects */ ];\ncookies = cookies.sort(cookieCompare);\n```\n\npermuteDomain(domain)\n---------------------\n\nGenerates a list of all possible domains that `domainMatch()` the parameter. May be handy for implementing cookie stores.\n\n\npermutePath(path)\n-----------------\n\nGenerates a list of all possible paths that `pathMatch()` the parameter. May be handy for implementing cookie stores.\n\nCookie\n======\n\nCookie.parse(header[,strict=false])\n-----------------------------------\n\nParses a single Cookie or Set-Cookie HTTP header into a `Cookie` object. Returns `undefined` if the string can't be parsed. If in strict mode, returns `undefined` if the cookie doesn't follow the guidelines in section 4 of RFC6265. Generally speaking, strict mode can be used to validate your own generated Set-Cookie headers, but acting as a client you want to be lenient and leave strict mode off.\n\nHere's how to process the Set-Cookie header(s) on a node HTTP/HTTPS response:\n\n``` javascript\nif (res.headers['set-cookie'] instanceof Array)\n cookies = res.headers['set-cookie'].map(function (c) { return (Cookie.parse(c)); });\nelse\n cookies = [Cookie.parse(res.headers['set-cookie'])];\n```\n\nCookie.fromJSON(string)\n-----------------------\n\nConvert a JSON string to a `Cookie` object. Does a `JSON.parse()` and converts the `.created`, `.lastAccessed` and `.expires` properties into `Date` objects.\n\nProperties\n==========\n\n * _key_ - string - the name or key of the cookie (default \"\")\n * _value_ - string - the value of the cookie (default \"\")\n * _expires_ - `Date` - if set, the `Expires=` attribute of the cookie (defaults to the string `\"Infinity\"`). See `setExpires()`\n * _maxAge_ - seconds - if set, the `Max-Age=` attribute _in seconds_ of the cookie. May also be set to strings `\"Infinity\"` and `\"-Infinity\"` for non-expiry and immediate-expiry, respectively. See `setMaxAge()`\n * _domain_ - string - the `Domain=` attribute of the cookie\n * _path_ - string - the `Path=` of the cookie\n * _secure_ - boolean - the `Secure` cookie flag\n * _httpOnly_ - boolean - the `HttpOnly` cookie flag\n * _extensions_ - `Array` - any unrecognized cookie attributes as strings (even if equal-signs inside)\n\nAfter a cookie has been passed through `CookieJar.setCookie()` it will have the following additional attributes:\n\n * _hostOnly_ - boolean - is this a host-only cookie (i.e. no Domain field was set, but was instead implied)\n * _pathIsDefault_ - boolean - if true, there was no Path field on the cookie and `defaultPath()` was used to derive one.\n * _created_ - `Date` - when this cookie was added to the jar\n * _lastAccessed_ - `Date` - last time the cookie got accessed. Will affect cookie cleaning once implemented. Using `cookiejar.getCookies(...)` will update this attribute.\n\nConstruction([{options}])\n------------\n\nReceives an options object that can contain any Cookie properties, uses the default for unspecified properties.\n\n.toString()\n-----------\n\nencode to a Set-Cookie header value. The Expires cookie field is set using `formatDate()`, but is omitted entirely if `.expires` is `Infinity`.\n\n.cookieString()\n---------------\n\nencode to a Cookie header value (i.e. the `.key` and `.value` properties joined with '=').\n\n.setExpires(String)\n-------------------\n\nsets the expiry based on a date-string passed through `parseDate()`. If parseDate returns `null` (i.e. can't parse this date string), `.expires` is set to `\"Infinity\"` (a string) is set.\n\n.setMaxAge(number)\n-------------------\n\nsets the maxAge in seconds. Coerces `-Infinity` to `\"-Infinity\"` and `Infinity` to `\"Infinity\"` so it JSON serializes correctly.\n\n.expiryTime([now=Date.now()])\n-----------------------------\n\n.expiryDate([now=Date.now()])\n-----------------------------\n\nexpiryTime() Computes the absolute unix-epoch milliseconds that this cookie expires. expiryDate() works similarly, except it returns a `Date` object. Note that in both cases the `now` parameter should be milliseconds.\n\nMax-Age takes precedence over Expires (as per the RFC). The `.created` attribute -- or, by default, the `now` paramter -- is used to offset the `.maxAge` attribute.\n\nIf Expires (`.expires`) is set, that's returned.\n\nOtherwise, `expiryTime()` returns `Infinity` and `expiryDate()` returns a `Date` object for \"Tue, 19 Jan 2038 03:14:07 GMT\" (latest date that can be expressed by a 32-bit `time_t`; the common limit for most user-agents).\n\n.TTL([now=Date.now()])\n---------\n\ncompute the TTL relative to `now` (milliseconds). The same precedence rules as for `expiryTime`/`expiryDate` apply.\n\nThe \"number\" `Infinity` is returned for cookies without an explicit expiry and `0` is returned if the cookie is expired. Otherwise a time-to-live in milliseconds is returned.\n\n.canonicalizedDoman()\n---------------------\n\n.cdomain()\n----------\n\nreturn the canonicalized `.domain` field. This is lower-cased and punycode (RFC3490) encoded if the domain has any non-ASCII characters.\n\n.validate()\n-----------\n\nStatus: *IN PROGRESS*. Works for a few things, but is by no means comprehensive.\n\nvalidates cookie attributes for semantic correctness. Useful for \"lint\" checking any Set-Cookie headers you generate. For now, it returns a boolean, but eventually could return a reason string -- you can future-proof with this construct:\n\n``` javascript\nif (cookie.validate() === true) {\n // it's tasty\n} else {\n // yuck!\n}\n```\n\nCookieJar\n=========\n\nConstruction([store = new MemoryCookieStore()][, rejectPublicSuffixes])\n------------\n\nSimply use `new CookieJar()`. If you'd like to use a custom store, pass that to the constructor otherwise a `MemoryCookieStore` will be created and used.\n\n\nAttributes\n----------\n\n * _rejectPublicSuffixes_ - boolean - reject cookies with domains like \"com\" and \"co.uk\" (default: `true`)\n\nSince eventually this module would like to support database/remote/etc. CookieJars, continuation passing style is used for CookieJar methods.\n\n.setCookie(cookieOrString, currentUrl, [{options},] cb(err,cookie))\n-------------------------------------------------------------------\n\nAttempt to set the cookie in the cookie jar. If the operation fails, an error will be given to the callback `cb`, otherwise the cookie is passed through. The cookie will have updated `.created`, `.lastAccessed` and `.hostOnly` properties.\n\nThe `options` object can be omitted and can have the following properties:\n\n * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.\n * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n * _strict_ - boolean - default `false` - perform extra checks\n * _ignoreError_ - boolean - default `false` - silently ignore things like parse errors and invalid domains. CookieStore errors aren't ignored by this option.\n\nAs per the RFC, the `.hostOnly` property is set if there was no \"Domain=\" parameter in the cookie string (or `.domain` was null on the Cookie object). The `.domain` property is set to the fully-qualified hostname of `currentUrl` in this case. Matching this cookie requires an exact hostname match (not a `domainMatch` as per usual).\n\n.setCookieSync(cookieOrString, currentUrl, [{options}])\n-------------------------------------------------------\n\nSynchronous version of `setCookie`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.storeCookie(cookie, [{options},] cb(err,cookie))\n-------------------------------------------------\n\n__REMOVED__ removed in lieu of the CookieStore API below\n\n.getCookies(currentUrl, [{options},] cb(err,cookies))\n-----------------------------------------------------\n\nRetrieve the list of cookies that can be sent in a Cookie header for the current url.\n\nIf an error is encountered, that's passed as `err` to the callback, otherwise an `Array` of `Cookie` objects is passed. The array is sorted with `cookieCompare()` unless the `{sort:false}` option is given.\n\nThe `options` object can be omitted and can have the following properties:\n\n * _http_ - boolean - default `true` - indicates if this is an HTTP or non-HTTP API. Affects HttpOnly cookies.\n * _secure_ - boolean - autodetect from url - indicates if this is a \"Secure\" API. If the currentUrl starts with `https:` or `wss:` then this is defaulted to `true`, otherwise `false`.\n * _now_ - Date - default `new Date()` - what to use for the creation/access time of cookies\n * _expire_ - boolean - default `true` - perform expiry-time checking of cookies and asynchronously remove expired cookies from the store. Using `false` will return expired cookies and **not** remove them from the store (which is useful for replaying Set-Cookie headers, potentially).\n * _allPaths_ - boolean - default `false` - if `true`, do not scope cookies by path. The default uses RFC-compliant path scoping. **Note**: may not be supported by the CookieStore `fetchCookies` function (the default MemoryCookieStore supports it).\n\nThe `.lastAccessed` property of the returned cookies will have been updated.\n\n.getCookiesSync(currentUrl, [{options}])\n----------------------------------------\n\nSynchronous version of `getCookies`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getCookieString(...)\n---------------------\n\nAccepts the same options as `.getCookies()` but passes a string suitable for a Cookie header rather than an array to the callback. Simply maps the `Cookie` array via `.cookieString()`.\n\n.getCookieStringSync(...)\n-------------------------\n\nSynchronous version of `getCookieString`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\n.getSetCookieStrings(...)\n-------------------------\n\nReturns an array of strings suitable for **Set-Cookie** headers. Accepts the same options as `.getCookies()`. Simply maps the cookie array via `.toString()`.\n\n.getSetCookieStringsSync(...)\n-----------------------------\n\nSynchronous version of `getSetCookieStrings`; only works with synchronous stores (e.g. the default `MemoryCookieStore`).\n\nStore\n=====\n\nBase class for CookieJar stores.\n\n# CookieStore API\n\nThe storage model for each `CookieJar` instance can be replaced with a custom implementation. The default is `MemoryCookieStore` which can be found in the `lib/memstore.js` file. The API uses continuation-passing-style to allow for asynchronous stores.\n\nStores should inherit from the base `Store` class, which is available as `require('tough-cookie').Store`. Stores are asynchronous by default, but if `store.synchronous` is set, then the `*Sync` methods on the CookieJar can be used.\n\nAll `domain` parameters will have been normalized before calling.\n\nThe Cookie store must have all of the following methods.\n\nstore.findCookie(domain, path, key, cb(err,cookie))\n---------------------------------------------------\n\nRetrieve a cookie with the given domain, path and key (a.k.a. name). The RFC maintains that exactly one of these cookies should exist in a store. If the store is using versioning, this means that the latest/newest such cookie should be returned.\n\nCallback takes an error and the resulting `Cookie` object. If no cookie is found then `null` MUST be passed instead (i.e. not an error).\n\nstore.findCookies(domain, path, cb(err,cookies))\n------------------------------------------------\n\nLocates cookies matching the given domain and path. This is most often called in the context of `cookiejar.getCookies()` above.\n\nIf no cookies are found, the callback MUST be passed an empty array.\n\nThe resulting list will be checked for applicability to the current request according to the RFC (domain-match, path-match, http-only-flag, secure-flag, expiry, etc.), so it's OK to use an optimistic search algorithm when implementing this method. However, the search algorithm used SHOULD try to find cookies that `domainMatch()` the domain and `pathMatch()` the path in order to limit the amount of checking that needs to be done.\n\nAs of version 0.9.12, the `allPaths` option to `cookiejar.getCookies()` above will cause the path here to be `null`. If the path is `null`, path-matching MUST NOT be performed (i.e. domain-matching only).\n\nstore.putCookie(cookie, cb(err))\n--------------------------------\n\nAdds a new cookie to the store. The implementation SHOULD replace any existing cookie with the same `.domain`, `.path`, and `.key` properties -- depending on the nature of the implementation, it's possible that between the call to `fetchCookie` and `putCookie` that a duplicate `putCookie` can occur.\n\nThe `cookie` object MUST NOT be modified; the caller will have already updated the `.creation` and `.lastAccessed` properties.\n\nPass an error if the cookie cannot be stored.\n\nstore.updateCookie(oldCookie, newCookie, cb(err))\n-------------------------------------------------\n\nUpdate an existing cookie. The implementation MUST update the `.value` for a cookie with the same `domain`, `.path` and `.key`. The implementation SHOULD check that the old value in the store is equivalent to `oldCookie` - how the conflict is resolved is up to the store.\n\nThe `.lastAccessed` property will always be different between the two objects and `.created` will always be the same. Stores MAY ignore or defer the `.lastAccessed` change at the cost of affecting how cookies are sorted (or selected for deletion).\n\nStores may wish to optimize changing the `.value` of the cookie in the store versus storing a new cookie. If the implementation doesn't define this method a stub that calls `putCookie(newCookie,cb)` will be added to the store object.\n\nThe `newCookie` and `oldCookie` objects MUST NOT be modified.\n\nPass an error if the newCookie cannot be stored.\n\nstore.removeCookie(domain, path, key, cb(err))\n----------------------------------------------\n\nRemove a cookie from the store (see notes on `findCookie` about the uniqueness constraint).\n\nThe implementation MUST NOT pass an error if the cookie doesn't exist; only pass an error due to the failure to remove an existing cookie.\n\nstore.removeCookies(domain, path, cb(err))\n------------------------------------------\n\nRemoves matching cookies from the store. The `path` paramter is optional, and if missing means all paths in a domain should be removed.\n\nPass an error ONLY if removing any existing cookies failed.\n\n# TODO\n\n * _full_ RFC5890/RFC5891 canonicalization for domains in `cdomain()`\n * the optional `punycode` requirement implements RFC3492, but RFC6265 requires RFC5891\n * better tests for `validate()`?\n\n# Copyright and License\n\n(tl;dr: MIT with some MPL/1.1)\n\nCopyright 2012- GoInstant, Inc. and other contributors.

It supports HTTPS and follows redirects by default.\n\n```javascript\nvar request = require('request');\nrequest('http://www.google.com', function (error, response, body) {\n if (!error && response.statusCode == 200) {\n console.log(body) // Print the google web page.\n }\n})\n```\n\n## Streaming\n\nYou can stream any response to a file stream.\n\n```javascript\nrequest('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))\n```\n\nYou can also stream a file to a PUT or POST request. This method will also check the file extension against a mapping of file extensions to content-types (in this case `application/json`) and use the proper `content-type` in the PUT request (if the headers don’t already provide one).\n\n```javascript\nfs.createReadStream('file.json').pipe(request.put('http://mysite.com/obj.json'))\n```\n\nRequest can also `pipe` to itself. When doing so, `content-type` and `content-length` are preserved in the PUT headers.\n\n```javascript\nrequest.get('http://google.com/img.png').pipe(request.put('http://mysite.com/img.png'))\n```\n\nNow let’s get fancy.\n\n```javascript\nhttp.createServer(function (req, resp) {\n if (req.url === '/doodle.png') {\n if (req.method === 'PUT') {\n req.pipe(request.put('http://mysite.com/doodle.png'))\n } else if (req.method === 'GET' || req.method === 'HEAD') {\n request.get('http://mysite.com/doodle.png').pipe(resp)\n }\n }\n})\n```\n\nYou can also `pipe()` from `http.ServerRequest` instances, as well as to `http.ServerResponse` instances. The HTTP method, headers, and entity-body data will be sent. Which means that, if you don't really care about security, you can do:\n\n```javascript\nhttp.createServer(function (req, resp) {\n if (req.url === '/doodle.png') {\n var x = request('http://mysite.com/doodle.png')\n req.pipe(x)\n x.pipe(resp)\n }\n})\n```\n\nAnd since `pipe()` returns the destination stream in ≥ Node 0.5.x you can do one line proxying. :)\n\n```javascript\nreq.pipe(request('http://mysite.com/doodle.png')).pipe(resp)\n```\n\nAlso, none of this new functionality conflicts with requests previous features, it just expands them.\n\n```javascript\nvar r = request.defaults({'proxy':'http://localproxy.com'})\n\nhttp.createServer(function (req, resp) {\n if (req.url === '/doodle.png') {\n r.get('http://google.com/doodle.png').pipe(resp)\n }\n})\n```\n\nYou can still use intermediate proxies, the requests will still follow HTTP forwards, etc.\n\n## UNIX Socket \n\n`request` supports the `unix://` protocol for all requests. The path is assumed to be absolute to the root of the host file system. \n\nHTTP paths are extracted from the supplied URL by testing each level of the full URL against net.connect for a socket response.\n\nThus the following request will GET `/httppath` from the HTTP server listening on `/tmp/unix.socket`\n\n```javascript\nrequest.get('unix://tmp/unix.socket/httppath')\n```\n\n## Forms\n\n`request` supports `application/x-www-form-urlencoded` and `multipart/form-data` form uploads. For `multipart/related` refer to the `multipart` API.\n\nURL-encoded forms are simple.\n\n```javascript\nrequest.post('http://service.com/upload', {form:{key:'value'}})\n// or\nrequest.post('http://service.com/upload').form({key:'value'})\n```\n\nFor `multipart/form-data` we use the [form-data](https://github.com/felixge/node-form-data) library by [@felixge](https://github.com/felixge). You don’t need to worry about piping the form object or setting the headers, `request` will handle that for you.\n\n```javascript\nvar r = request.post('http://service.com/upload')\nvar form = r.form()\nform.append('my_field', 'my_value')\nform.append('my_buffer', new Buffer([1, 2, 3]))\nform.append('my_file', fs.createReadStream(path.join(__dirname, 'doodle.png'))\nform.append('remote_file', request('http://google.com/doodle.png'))\n```\n\n## HTTP Authentication\n\n```javascript\nrequest.get('http://some.server.com/').auth('username', 'password', false);\n// or\nrequest.get('http://some.server.com/', {\n 'auth': {\n 'user': 'username',\n 'pass': 'password',\n 'sendImmediately': false\n }\n});\n```\n\nIf passed as an option, `auth` should be a hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional). The method form takes parameters `auth(username, password, sendImmediately)`.\n\n`sendImmediately` defaults to `true`, which causes a basic authentication header to be sent. If `sendImmediately` is `false`, then `request` will retry with a proper authentication header after receiving a `401` response from the server (which must contain a `WWW-Authenticate` header indicating the required authentication method).\n\nDigest authentication is supported, but it only works with `sendImmediately` set to `false`; otherwise `request` will send basic authentication on the initial request, which will probably cause the request to fail.\n\n## OAuth Signing\n\n```javascript\n// Twitter OAuth\nvar qs = require('querystring')\n , oauth =\n { callback: 'http://mysite.com/callback/'\n , consumer_key: CONSUMER_KEY\n , consumer_secret: CONSUMER_SECRET\n }\n , url = 'https://api.twitter.com/oauth/request_token'\n ;\nrequest.post({url:url, oauth:oauth}, function (e, r, body) {\n // Ideally, you would take the body in the response\n // and construct a URL that a user clicks on (like a sign in button).\n // The verifier is only available in the response after a user has\n // verified with twitter that they are authorizing your app.\n var access_token = qs.parse(body)\n , oauth =\n { consumer_key: CONSUMER_KEY\n , consumer_secret: CONSUMER_SECRET\n , token: access_token.oauth_token\n , verifier: access_token.oauth_verifier\n }\n , url = 'https://api.twitter.com/oauth/access_token'\n ;\n request.post({url:url, oauth:oauth}, function (e, r, body) {\n var perm_token = qs.parse(body)\n , oauth =\n { consumer_key: CONSUMER_KEY\n , consumer_secret: CONSUMER_SECRET\n , token: perm_token.oauth_token\n , token_secret: perm_token.oauth_token_secret\n }\n , url = 'https://api.twitter.com/1.1/users/show.json?'\n , params =\n { screen_name: perm_token.screen_name\n , user_id: perm_token.user_id\n }\n ;\n url += qs.stringify(params)\n request.get({url:url, oauth:oauth, json:true}, function (e, r, user) {\n console.log(user)\n })\n })\n})\n```\n\n### Custom HTTP Headers\n\nHTTP Headers, such as `User-Agent`, can be set in the `options` object.\nIn the example below, we call the github API to find out the number\nof stars and forks for the request repository. This requires a\ncustom `User-Agent` header as well as https.\n\n```javascript\nvar request = require('request');\n\nvar options = {\n\turl: 'https://api.github.com/repos/mikeal/request',\n\theaders: {\n\t\t'User-Agent': 'request'\n\t}\n};\n\nfunction callback(error, response, body) {\n\tif (!error && response.statusCode == 200) {\n\t\tvar info = JSON.parse(body);\n\t\tconsole.log(info.stargazers_count + \" Stars\");\n\t\tconsole.log(info.forks_count + \" Forks\");\n\t}\n}\n\nrequest(options, callback);\n```\n\n### request(options, callback)\n\nThe first argument can be either a `url` or an `options` object. The only required option is `uri`; all others are optional.\n\n* `uri` || `url` - fully qualified uri or a parsed url object from `url.parse()`\n* `qs` - object containing querystring values to be appended to the `uri`\n* `method` - http method (default: `\"GET\"`)\n* `headers` - http headers (default: `{}`)\n* `body` - entity body for PATCH, POST and PUT requests. Must be a `Buffer` or `String`.\n* `form` - when passed an object, this sets `body` to a querystring representation of value, and adds `Content-type: application/x-www-form-urlencoded; charset=utf-8` header. When passed no options, a `FormData` instance is returned (and is piped to request).\n* `auth` - A hash containing values `user` || `username`, `password` || `pass`, and `sendImmediately` (optional). See documentation above.\n* `json` - sets `body` but to JSON representation of value and adds `Content-type: application/json` header. Additionally, parses the response body as JSON.\n* `multipart` - (experimental) array of objects which contains their own headers and `body` attribute. Sends `multipart/related` request. See example below.\n* `followRedirect` - follow HTTP 3xx responses as redirects (default: `true`)\n* `followAllRedirects` - follow non-GET HTTP 3xx responses as redirects (default: `false`)\n* `maxRedirects` - the maximum number of redirects to follow (default: `10`)\n* `encoding` - Encoding to be used on `setEncoding` of response data. If `null`, the `body` is returned as a `Buffer`.\n* `pool` - A hash object containing the agents for these requests. If omitted, the request will use the global pool (which is set to node's default `maxSockets`)\n* `pool.maxSockets` - Integer containing the maximum amount of sockets in the pool.\n* `timeout` - Integer containing the number of milliseconds to wait for a request to respond before aborting the request\n* `proxy` - An HTTP proxy to be used. Supports proxy Auth with Basic Auth, identical to support for the `url` parameter (by embedding the auth info in the `uri`)\n* `oauth` - Options for OAuth HMAC-SHA1 signing. See documentation above.\n* `hawk` - Options for [Hawk signing](https://github.com/hueniverse/hawk). The `credentials` key must contain the necessary signing info, [see hawk docs for details](https://github.com/hueniverse/hawk#usage-example).\n* `strictSSL` - If `true`, requires SSL certificates be valid. **Note:** to use your own certificate authority, you need to specify an agent that was created with that CA as an option.\n* `jar` - If `true`, remember cookies for future use (or define your custom cookie jar; see examples section)\n* `aws` - `object` containing AWS signing information. Should have the properties `key`, `secret`. Also requires the property `bucket`, unless you’re specifying your `bucket` as part of the path, or the request doesn’t use a bucket (i.e. GET Services)\n* `httpSignature` - Options for the [HTTP Signature Scheme](https://github.com/joyent/node-http-signature/blob/master/http_signing.md) using [Joyent's library](https://github.com/joyent/node-http-signature). The `keyId` and `key` properties must be specified. See the docs for other options.\n* `localAddress` - Local interface to bind for network connections.\n\n\nThe callback argument gets 3 arguments: \n\n1. An `error` when applicable (usually from [`http.ClientRequest`](http://nodejs.org/api/http.html#http_class_http_clientrequest) object)\n2. An [`http.IncomingMessage`](http://nodejs.org/api/http.html#http_http_incomingmessage) object\n3. The third is the `response` body (`String` or `Buffer`, or JSON object if the `json` option is supplied)\n\n## Convenience methods\n\nThere are also shorthand methods for different HTTP METHODs and some other conveniences.\n\n### request.defaults(options)\n\nThis method returns a wrapper around the normal request API that defaults to whatever options you pass in to it.\n\n### request.put\n\nSame as `request()`, but defaults to `method: \"PUT\"`.\n\n```javascript\nrequest.put(url)\n```\n\n### request.patch\n\nSame as `request()`, but defaults to `method: \"PATCH\"`.\n\n```javascript\nrequest.patch(url)\n```\n\n### request.post\n\nSame as `request()`, but defaults to `method: \"POST\"`.\n\n```javascript\nrequest.post(url)\n```\n\n### request.head\n\nSame as request() but defaults to `method: \"HEAD\"`.\n\n```javascript\nrequest.head(url)\n```\n\n### request.del\n\nSame as `request()`, but defaults to `method: \"DELETE\"`.\n\n```javascript\nrequest.del(url)\n```\n\n### request.get\n\nSame as `request()` (for uniformity).\n\n```javascript\nrequest.get(url)\n```\n### request.cookie\n\nFunction that creates a new cookie.\n\n```javascript\nrequest.cookie('cookie_string_here')\n```\n### request.jar\n\nFunction that creates a new cookie jar.\n\n```javascript\nrequest.jar()\n```\n\n\n## Examples:\n\n```javascript\n var request = require('request')\n , rand = Math.floor(Math.random()*100000000).toString()\n ;\n request(\n { method: 'PUT'\n , uri: 'http://mikeal.iriscouch.com/testjs/' + rand\n , multipart:\n [ { 'content-type': 'application/json'\n , body: JSON.stringify({foo: 'bar', _attachments: {'message.txt': {follows: true, length: 18, 'content_type': 'text/plain' }}})\n }\n , { body: 'I am an attachment' }\n ]\n }\n , function (error, response, body) {\n if(response.statusCode == 201){\n console.log('document saved as: http://mikeal.iriscouch.com/testjs/'+ rand)\n } else {\n console.log('error: '+ response.statusCode)\n console.log(body)\n }\n }\n )\n```\n\nCookies are disabled by default (else, they would be used in subsequent requests). To enable cookies, set `jar` to `true` (either in `defaults` or `options`).\n\n```javascript\nvar request = request.defaults({jar: true})\nrequest('http://www.google.com', function () {\n request('http://images.google.com')\n})\n```\n\nTo use a custom cookie jar (instead `request`’s global cookie jar), set `jar` to an instance of `request.jar()` (either in `defaults` or `options`)\n\n```javascript\nvar j = request.jar()\nvar request = request.defaults({jar:j})\nrequest('http://www.google.com', function () {\n request('http://images.google.com')\n})\n```\n\nOR\n\n```javascript\nvar j = request.jar()\nvar cookie = request.cookie('your_cookie_here')\nj.setCookie(cookie, uri);\nrequest({url: 'http://www.google.com', jar: j}, function () {\n request('http://images.google.com')\n})\n```\n", + "readmeFilename": "README.md", + "_id": "request@2.34.0", + "dist": { + "shasum": "b5d8b9526add4a2d4629f4d417124573996445ae" + }, + "_from": "request@>=2.12.0", + "_resolved": "https://registry.npmjs.org/request/-/request-2.34.0.tgz" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/request/request.js b/node_modules/less-middleware/node_modules/less/node_modules/request/request.js new file mode 100644 index 0000000..4ed8e0c --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/request/request.js @@ -0,0 +1,1342 @@ +var optional = require('./lib/optional') + , http = require('http') + , https = optional('https') + , tls = optional('tls') + , url = require('url') + , util = require('util') + , stream = require('stream') + , qs = require('qs') + , querystring = require('querystring') + , crypto = require('crypto') + + , oauth = optional('oauth-sign') + , hawk = optional('hawk') + , aws = optional('aws-sign2') + , httpSignature = optional('http-signature') + , uuid = require('node-uuid') + , mime = require('mime') + , tunnel = optional('tunnel-agent') + , _safeStringify = require('json-stringify-safe') + + , ForeverAgent = require('forever-agent') + , FormData = optional('form-data') + + , cookies = require('./lib/cookies') + , globalCookieJar = cookies.jar() + + , copy = require('./lib/copy') + , debug = require('./lib/debug') + , getSafe = require('./lib/getSafe') + , net = require('net') + ; + +function safeStringify (obj) { + var ret + try { ret = JSON.stringify(obj) } + catch (e) { ret = _safeStringify(obj) } + return ret +} + +var globalPool = {} +var isUrl = /^https?:|^unix:/ + + +// Hacky fix for pre-0.4.4 https +if (https && !https.Agent) { + https.Agent = function (options) { + http.Agent.call(this, options) + } + util.inherits(https.Agent, http.Agent) + https.Agent.prototype._getConnection = function (host, port, cb) { + var s = tls.connect(port, host, this.options, function () { + // do other checks here?

If that is you, but still want to author +in AMD style modules to get dynamic require([]), better direct source usage and +powerful loader plugin support in the browser, then this tool can help. + +#### amdefine/intercept usage + +Just require it in your top level app module (for example index.js, server.js): + +```javascript +require('amdefine/intercept'); +``` + +The module does not return a value, so no need to assign the result to a local +variable. + +Then just require() code as you normally would with Node's require(). Any .js +loaded after the intercept require will have the amdefine check injected in +the .js source as it is loaded. It does not modify the source on disk, just +prepends some content to the text of the module as it is loaded by Node. + +#### How amdefine/intercept works + +It overrides the `Module._extensions['.js']` in Node to automatically prepend +the amdefine snippet above. So, it will affect any .js file loaded by your +app. + +## define() usage + +It is best if you use the anonymous forms of define() in your module: + +```javascript +define(function (require) { + var dependency = require('dependency'); +}); +``` + +or + +```javascript +define(['dependency'], function (dependency) { + +}); +``` + +## RequireJS optimizer integration.
    + +Version 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html) +will have support for stripping the `if (typeof define !== 'function')` check +mentioned above, so you can include this snippet for code that runs in the +browser, but avoid taking the cost of the if() statement once the code is +optimized for deployment. + +## Node 0.4 Support + +If you want to support Node 0.4, then add `require` as the second parameter to amdefine: + +```javascript +//Only if you want Node 0.4. If using 0.5 or later, use the above snippet. +if (typeof define !== 'function') { var define = require('amdefine')(module, require) } +``` + +## Limitations + +### Synchronous vs Asynchronous + +amdefine creates a define() function that is callable by your code. It will +execute and trace dependencies and call the factory function *synchronously*, +to keep the behavior in line with Node's synchronous dependency tracing. + +The exception: calling AMD's callback-style require() from inside a factory +function. The require callback is called on process.nextTick(): + +```javascript +define(function (require) { + require(['a'], function(a) { + //'a' is loaded synchronously, but + //this callback is called on process.nextTick(). + }); +}); +``` + +### Loader Plugins + +Loader plugins are supported as long as they call their load() callbacks +synchronously. So ones that do network requests will not work. However plugins +like [text](http://requirejs.org/docs/api.html#text) can load text files locally. + +The plugin API's `load.fromText()` is **not supported** in amdefine, so this means +transpiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs) +will not work. This may be fixable, but it is a bit complex, and I do not have +enough node-fu to figure it out yet. See the source for amdefine.js if you want +to get an idea of the issues involved. + +## Tests + +To run the tests, cd to **tests** and run: + +``` +node all.js +node all-intercept.js +``` + +## License + +New BSD and MIT.

It does not modify the source on disk, just\nprepends some content to the text of the module as it is loaded by Node.\n\n#### How amdefine/intercept works\n\nIt overrides the `Module._extensions['.js']` in Node to automatically prepend\nthe amdefine snippet above. So, it will affect any .js file loaded by your\napp.\n\n## define() usage\n\nIt is best if you use the anonymous forms of define() in your module:\n\n```javascript\ndefine(function (require) {\n var dependency = require('dependency');\n});\n```\n\nor\n\n```javascript\ndefine(['dependency'], function (dependency) {\n\n});\n```\n\n## RequireJS optimizer integration. \n\nVersion 1.0.3 of the [RequireJS optimizer](http://requirejs.org/docs/optimization.html)\nwill have support for stripping the `if (typeof define !== 'function')` check\nmentioned above, so you can include this snippet for code that runs in the\nbrowser, but avoid taking the cost of the if() statement once the code is\noptimized for deployment.\n\n## Node 0.4 Support\n\nIf you want to support Node 0.4, then add `require` as the second parameter to amdefine:\n\n```javascript\n//Only if you want Node 0.4. If using 0.5 or later, use the above snippet.\nif (typeof define !== 'function') { var define = require('amdefine')(module, require) }\n```\n\n## Limitations\n\n### Synchronous vs Asynchronous\n\namdefine creates a define() function that is callable by your code. It will\nexecute and trace dependencies and call the factory function *synchronously*,\nto keep the behavior in line with Node's synchronous dependency tracing.\n\nThe exception: calling AMD's callback-style require() from inside a factory\nfunction. The require callback is called on process.nextTick():\n\n```javascript\ndefine(function (require) {\n require(['a'], function(a) {\n //'a' is loaded synchronously, but\n //this callback is called on process.nextTick().\n });\n});\n```\n\n### Loader Plugins\n\nLoader plugins are supported as long as they call their load() callbacks\nsynchronously. So ones that do network requests will not work. However plugins\nlike [text](http://requirejs.org/docs/api.html#text) can load text files locally.\n\nThe plugin API's `load.fromText()` is **not supported** in amdefine, so this means\ntranspiler plugins like the [CoffeeScript loader plugin](https://github.com/jrburke/require-cs)\nwill not work. This may be fixable, but it is a bit complex, and I do not have\nenough node-fu to figure it out yet. See the source for amdefine.js if you want\nto get an idea of the issues involved.\n\n## Tests\n\nTo run the tests, cd to **tests** and run:\n\n```\nnode all.js\nnode all-intercept.js\n```\n\n## License\n\nNew BSD and MIT.

The walking function is called for each\nsource file content and is passed the filename and source content.\n\n* `fn`: The traversal function.\n\n#### SourceNode.prototype.join(sep)\n\nLike `Array.prototype.join` except for SourceNodes. Inserts the separator\nbetween each of this source node's children.\n\n* `sep`: The separator.\n\n#### SourceNode.prototype.replaceRight(pattern, replacement)\n\nCall `String.prototype.replace` on the very right-most source snippet.

You have\naccess to the following assertion functions:\n\n* `doesNotThrow`\n\n* `equal`\n\n* `ok`\n\n* `strictEqual`\n\n* `throws`\n\n(The reason for the restricted set of test functions is because we need the\ntests to run inside Firefox's test suite as well and so the assert module is\nshimmed in that environment. See `build/assert-shim.js`.)\n\n[format]: https://docs.google.com/document/d/1U1RGAehQwRypUTovF1KRlpiOFze0b-_2gc6fAH0KY0k/edit\n[feature]: https://wiki.mozilla.org/DevTools/Features/SourceMap\n[Dryice]: https://github.com/mozilla/dryice\n", + "readmeFilename": "README.md", + "bugs": { + "url": "https://github.com/mozilla/source-map/issues" + }, + "_id": "source-map@0.1.32", + "dist": { + "shasum": "ad52a5b0756bc13612cb90d5fb5e8a332e1f2587" + }, + "_from": "source-map@0.1.x", + "_resolved": "https://registry.npmjs.org/source-map/-/source-map-0.1.32.tgz" +} diff --git a/node_modules/less-middleware/node_modules/less/node_modules/source-map/test/run-tests.js b/node_modules/less-middleware/node_modules/less/node_modules/source-map/test/run-tests.js new file mode 100755 index 0000000..64a7c3a --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/node_modules/source-map/test/run-tests.js @@ -0,0 +1,62 @@ +#!/usr/bin/env node +/* -*- Mode: js; js-indent-level: 2; -*- */ +/* + * Copyright 2011 Mozilla Foundation and contributors + * Licensed under the New BSD license.

[http://lesscss.org](http://lesscss.org).\r\n\r\nThis is the JavaScript, and now official, stable version of LESS.\r\n\r\n\r\n## Getting Started\r\n\r\nOptions for adding Less.js to your project:\r\n\r\n* Install with [NPM](https://npmjs.org/): `npm install less`\r\n* [Download the latest release][download]\r\n* Clone the repo: `git clone git://github.com/less/less.js.git`\r\n\r\n\r\n\r\n## Feature Highlights\r\nLESS extends CSS with dynamic features such as:\r\n\r\n* [nesting](#nesting)\r\n* [variables](#variables)\r\n* [operations](#operations)\r\n* [mixins](#mixins)\r\n* [extend](#extend) (selector inheritance)\r\n\r\nTo learn about the many other features Less.js has to offer please visit [http://lesscss.org](http://lesscss.org) and [the Less.js wiki][wiki]\r\n\r\n\r\n### Examples\r\n#### nesting\r\nTake advantage of nesting to make code more readable and maintainable. This:\r\n\r\n```less\r\n.nav > li > a {\r\n border: 1px solid #f5f5f5;\r\n &:hover {\r\n border-color: #ddd;\r\n }\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.nav > li > a {\r\n border: 1px solid #f5f5f5;\r\n}\r\n.nav > li > a:hover {\r\n border-color: #ddd;\r\n}\r\n```\r\n\r\n\r\n#### variables\r\nUpdated commonly used values from a single location.\r\n\r\n```less\r\n// Variables (\"inline\" comments like this can be used)\r\n@link-color: #428bca; // appears as \"sea blue\"\r\n\r\n/* Or \"block comments\" that span\r\n multiple lines, like this */\r\na {\r\n color: @link-color; // use the variable in styles\r\n}\r\n```\r\n\r\nVariables can also be used in `@import` statements, URLs, selector names, and more.\r\n\r\n\r\n\r\n#### operations\r\nContinuing with the same example above, we can use our variables even easier to maintain with _operations_, which enables the use of addition, subraction, multiplication and division in your styles:\r\n\r\n```less\r\n// Variables\r\n@link-color: #428bca;\r\n@link-color-hover: darken(@link-color, 10%);\r\n\r\n// Styles\r\na {\r\n color: @link-color;\r\n}\r\na:hover {\r\n color: @link-color-hover;\r\n}\r\n```\r\nrenders to:\r\n\r\n```css\r\na {\r\n color: #428bca;\r\n}\r\na:hover {\r\n color: #3071a9;\r\n}\r\n```\r\n\r\n#### mixins\r\n##### \"implicit\" mixins\r\nMixins enable you to apply the styles of one selector inside another selector like this:\r\n\r\n```less\r\n// Variables\r\n@link-color: #428bca;\r\n\r\n// Any \"regular\" class...\r\n.link {\r\n color: @link-color;\r\n}\r\na {\r\n font-weight: bold;\r\n .link; // ...can be used as an \"implicit\" mixin\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.link {\r\n color: #428bca;\r\n}\r\na {\r\n font-weight: bold;\r\n color: #428bca;\r\n}\r\n```\r\n\r\nSo any selector can be an \"implicit mixin\". We'll show you a DRYer way to do this below.\r\n\r\n\r\n\r\n##### parametric mixins\r\nMixins can also accept parameters:\r\n\r\n```less\r\n// Transition mixin\r\n.transition(@transition) {\r\n -webkit-transition: @transition;\r\n -moz-transition: @transition;\r\n -o-transition: @transition;\r\n transition: @transition;\r\n}\r\n```\r\n\r\nused like this:\r\n\r\n```less\r\n// Variables\r\n@link-color: #428bca;\r\n@link-color-hover: darken(@link-color, 10%);\r\n\r\n//Transition mixin would be anywhere here\r\n\r\na {\r\n font-weight: bold;\r\n color: @link-color;\r\n .transition(color .2s ease-in-out);\r\n // Hover state\r\n &:hover {\r\n color: @link-color-hover;\r\n }\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\na {\r\n font-weight: bold;\r\n color: #428bca;\r\n -webkit-transition: color 0.2s ease-in-out;\r\n -moz-transition: color 0.2s ease-in-out;\r\n -o-transition: color 0.2s ease-in-out;\r\n transition: color 0.2s ease-in-out;\r\n}\r\na:hover {\r\n color: #3071a9;\r\n}\r\n```\r\n\r\n\r\n#### extend\r\nThe `extend` feature can be thought of as the _inverse_ of mixins. It accomplishes the goal of \"borrowing styles\", but rather than copying all the rules of _Selector A_ over to _Selector B_, `extend` copies the name of the _inheriting selector_ (_Selector B_) over to the _extending selector_ (_Selector A_). So continuing with the example used for [mixins](#mixins) above, extend works like this:\r\n\r\n```less\r\n// Variables\r\n@link-color: #428bca;\r\n\r\n.link {\r\n color: @link-color;\r\n}\r\na:extend(.link) {\r\n font-weight: bold;\r\n}\r\n// Can also be written as\r\na {\r\n &:extend(.link);\r\n font-weight: bold;\r\n}\r\n```\r\n\r\nrenders to:\r\n\r\n```css\r\n.link, a {\r\n color: #428bca;\r\n}\r\na {\r\n font-weight: bold;\r\n}\r\n```\r\n\r\n## Usage\r\n\r\n### Compiling and Parsing\r\nInvoke the compiler from node:\r\n\r\n```javascript\r\nvar less = require('less');\r\n\r\nless.render('.class { width: (1 + 1) }', function (e, css) {\r\n console.log(css);\r\n});\r\n```\r\n\r\nOutputs:\r\n\r\n```css\r\n.class {\r\n width: 2;\r\n}\r\n```\r\n\r\nYou may also manually invoke the parser and compiler:\r\n\r\n```javascript\r\nvar parser = new(less.Parser);\r\n\r\nparser.parse('.class { width: (1 + 1) }', function (err, tree) {\r\n if (err) { return console.error(err) }\r\n console.log(tree.toCSS());\r\n});\r\n```\r\n\r\n\r\n### Configuration\r\nYou may also pass options to the compiler:\r\n\r\n```javascript\r\nvar parser = new(less.Parser)({\r\n paths: ['.', './src/less'], // Specify search paths for @import directives\r\n filename: 'style.less' // Specify a filename, for better error messages\r\n});\r\n\r\nparser.parse('.class { width: (1 + 1) }', function (e, tree) {\r\n tree.toCSS({ compress: true }); // Minify CSS output\r\n});\r\n```\r\n\r\n## More information\r\n\r\nFor general information on the language, configuration options or usage visit [lesscss.org](http://lesscss.org) or [the less wiki][wiki].\r\n\r\nHere are other resources for using Less.js:\r\n\r\n* [stackoverflow.com][so] is a great place to get answers about Less.\r\n* [node.js tools](https://github.com/less/less.js/wiki/Converting-LESS-to-CSS) for converting Less to CSS\r\n* [GUI compilers for Less](https://github.com/less/less.js/wiki/GUI-compilers-that-use-LESS.js)\r\n* [Less.js Issues][issues] for reporting bugs\r\n\r\n\r\n\r\n## Contributing\r\nPlease read [CONTRIBUTING.md](./CONTRIBUTING.md). Add unit tests for any new or changed functionality. Lint and test your code using [Grunt](http://gruntjs.com/).\r\n\r\n### Reporting Issues\r\n\r\nBefore opening any issue, please search for existing issues and read the [Issue Guidelines](https://github.com/necolas/issue-guidelines), written by [Nicolas Gallagher](https://github.com/necolas/). After that if you find a bug or would like to make feature request, [please open a new issue][issues].\r\n\r\nPlease report documentation issues in [the documentation project](https://github.com/less/less-docs).\r\n\r\n### Development\r\n\r\n#### Install Less.js\r\n\r\nStart by either [downloading this project][download] manually, or in the command line:\r\n\r\n```shell\r\ngit clone https://github.com/less/less.js.git \"less\"\r\n```\r\nand then `cd less`.\r\n\r\n\r\n#### Install dependencies\r\n\r\nTo install all the dependencies for less development, run:\r\n\r\n```shell\r\nnpm install\r\n```\r\n\r\nIf you haven't run grunt before, install grunt-cli globally so you can just run `grunt`\r\n\r\n```shell\r\nnpm install grunt-cli -g\r\n```\r\n\r\nYou should now be able to build Less.js, run tests, benchmarking, and other tasks listed in the Gruntfile.\r\n\r\n## Using Less.js Grunt\r\n\r\nTests, benchmarking and building is done using Grunt `~0.4.1`. If you haven't used [Grunt](http://gruntjs.com/) before, be sure to check out the [Getting Started](http://gruntjs.com/getting-started) guide, as it explains how to install and use Grunt plugins, which are necessary for development with Less.js.\r\n\r\nThe Less.js [Gruntfile](Gruntfile.js) is configured with the following \"convenience tasks\" :\r\n\r\n#### test - `grunt`\r\nRuns jshint, nodeunit and headless jasmine tests using [phantomjs](http://code.google.com/p/phantomjs/). You must have phantomjs installed for the jasmine tests to run.\r\n\r\n#### test - `grunt benchmark`\r\nRuns the benchmark suite.\r\n\r\n#### build for testing browser - 'grunt browser'\r\nThis builds less.js and puts it in 'test/browser/less.js'\r\n\r\n#### build - `grunt stable | grunt beta | grunt alpha`\r\nBuilds Less.js from from the `/lib/less` source files. This is done by the developer releasing a new release, do not do this if you are creating a pull request.\r\n\r\n#### readme - `grunt readme`\r\nBuild the README file from [a template](build/README.md) to ensure that metadata is up-to-date and (more likely to be) correct.\r\n\r\nPlease review the [Gruntfile](Gruntfile.js) to become acquainted with the other available tasks.\r\n\r\n**Please note** that if you have any issues installing dependencies or running any of the Gruntfile commands, please make sure to uninstall any previous versions, both in the local node_modules directory, and clear your global npm cache, and then try running `npm install` again. After that if you still have issues, please let us know about it so we can help.\r\n\r\n\r\n## Release History\r\nSee the [changelog](CHANGELOG.md)\r\n\r\n## [License](LICENSE)\r\n\r\nCopyright (c) 2009-2014 [Alexis Sellier](http://cloudhead.io/) & The Core Less Team\r\nLicensed under the [Apache License](LICENSE).\r\n\r\n\r\n[so]: http://stackoverflow.com/questions/tagged/twitter-bootstrap+less \"StackOverflow.com\"\r\n[issues]: https://github.com/less/less.js/issues \"GitHub Issues for Less.js\"\r\n[wiki]: https://github.com/less/less.js/wiki \"The official wiki for Less.js\"\r\n[download]: https://github.com/less/less.js/zipball/master \"Download Less.js\"", + "readmeFilename": "README.md", + "dependencies": { + "mime": "1.2.x", + "request": ">=2.12.0", + "mkdirp": "~0.3.5", + "clean-css": "2.0.x", + "source-map": "0.1.x" + }, + "_id": "less@1.6.3", + "dist": { + "shasum": "bdbcc0d3432ff05a470c672f6c5c6543f72e4ce4" + }, + "_from": "less@~1.6.1", + "_resolved": "https://registry.npmjs.org/less/-/less-1.6.3.tgz" +} diff --git a/node_modules/less-middleware/node_modules/less/projectFilesBackup/.idea/libraries/sass_stdlib.xml b/node_modules/less-middleware/node_modules/less/projectFilesBackup/.idea/libraries/sass_stdlib.xml new file mode 100644 index 0000000..8962a7d --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/projectFilesBackup/.idea/libraries/sass_stdlib.xml @@ -0,0 +1,8 @@ + + + + + + + + \ No newline at end of file diff --git a/node_modules/less-middleware/node_modules/less/test/browser/common.js b/node_modules/less-middleware/node_modules/less/test/browser/common.js new file mode 100644 index 0000000..6e2bb38 --- /dev/null +++ b/node_modules/less-middleware/node_modules/less/test/browser/common.js @@ -0,0 +1,201 @@ +/* record log messages for testing */ +// var logAllIds = function() { +// var allTags = document.head.getElementsByTagName('style');

    \n\n## Examples\n\n### Connect\n```js\nvar lessMiddleware = require('less-middleware');\n\nvar server = connect.createServer(\n lessMiddleware({\n src: __dirname + '/public',\n compress: true\n }),\n connect.staticProvider(__dirname + '/public')\n);\n```\n\n### Express\n\n```js\nvar lessMiddleware = require('less-middleware');\n\nvar app = express();\n\napp.configure(function () {\n // Other configuration here...\n\n app.use(lessMiddleware({\n src: __dirname + '/public',\n compress: true\n }));\n\n app.use(express.static(__dirname + '/public'));\n});\n```\n\n### Express - Different `src` and `dest`\n\nWhen using a different `src` and `dest` you can use the `prefix` option to make the directory structure cleaner.\n\nRequests for static assets (like stylesheets) made to the express server use a `pathname` to look up the file. So if the request is for `http://localhost/stylesheets/styles.css` the `pathname` will be `/stylesheets/styles.css`.\n\nThe less middleware uses that path to determine where to look for less files. In the original example it looks for the less file at `/public/stylesheets/styles.less` and compiles it to `/public/stylesheets/styles.css`.\n\nIf you are using a different `src` and `dest` options it causes for more complex directories structures unless you use the `prefix` option. For example, without the `prefix`, and with a `src` of `/src/less` and a `dest` of `/public` it would look for the less file at `/src/less/stylesheets/styles.less` and compile it to `/public/stylesheets/styles.css`. To make it cleaner you can use the `prefix` option:\n\n```js\nvar lessMiddleware = require('less-middleware');\n\nvar app = express();\n\napp.configure(function () {\n // Other configuration here...\n\n app.use(lessMiddleware({\n dest: __dirname + '/public/stylesheets',\n src: __dirname + '/src/less',\n prefix: '/stylesheets',\n compress: true\n }));\n\n app.use(express.static(__dirname + '/public'));\n});\n```\n\nUsing the `prefix` it changes the `pathname` from `/stylesheets/styles.css` to `/styles.css`. With that prefix removed from the `pathname` it makes things cleaner. With the `prefix` removed it would look for the less file at `/src/less/styles.less` and compile it to `/public/stylesheets/styles.css`.\n\nA new alternative way to achieve the same thing as using prefix but with greater flexibility is to supply a shared root value. From this shared root, you would specify a URI style path to the appropriate source and destination directories:\n\n```js\nvar lessMiddleware = require('less-middleware')\n , path = require('path')\n , pubDir = path.join(__dirname, 'public')\n , app = express();\n \napp.configure(function() {\n app.use(lessMiddleware({\n dest: '/css', // should be the URI to your css directory from the location bar in your browser\n src: '/less', // or '../less' if the less directory is outside of /public\n root: pubDir,\n compress: true\n }));\n \n app.use(express.static(pubDir));\n});\n```\n\nThis will allow any file under the /less directory, including subdirectories, to be compiled into an identical directory structure under /css.\n\n### Express - Using a temp directory for `dest`\n\nSince less middleware relies on static content to be served by express.static, using temp directories just requires that you inform express about where generated files are built:\n\n```js\nvar lessMiddleware = require('less-middleware'),\n os = require('os');\n\nvar app = express();\n\napp.configure(function () {\n // Other configuration here...\n\n var tmpDir = os.tmpDir();\n app.use(lessMiddleware({\n src: __dirname + '/public/stylesheets',\n dest: tmpDir,\n compress: true\n }));\n\n app.use(express.static(__dirname + '/public'));\n app.use(express.static(tmpDir));\n});\n```\n\nUsing a temp directory is useful for read-only file systems, such as a Heroku deployment. By using a temp directory the css files can still be written and served.\n\n### Importing less\n\nBy default the directory in which the compiled files live in is already set as an import directive:\n\n```css\n// file1.less\n\n@import 'file2.less';\n\nbody {\n color: @bodyColor;\n}\n```\n\n```css\n// file2.less\n\n@bodyColor: #333333;\n```\n\nHowever, you can use the `paths` option if you need to specify other directories in which to search for importable less files.\n\n```js\nvar less = require('less-middleware'),\n path = require('path');\n\n lessMiddleware({\n src: path.join(__dirname, 'public'),\n paths: [path.join(__dirname, 'module', 'less')]\n });\n```\n\n```css\n// public/base.css\n\n@import 'colors';\n\nbody {\n color: @bodyColor;\n}\n```\n\n```css\n// module/less/colors.less\n\n@bodyColor: #333333;\n```\n\n### Using bootstrap\n\nHere's an example on how to use Twitter's bootstrap within an Express.js set-up:\n\n```js\n// package.json\n{\n \"name\": \"my-module\",\n // ...\n \"dependencies\": {\n \"less-middleware\": \"*\",\n \"bootstrap\": \"git+https://github.com/twitter/bootstrap.git#v2.2.2\",\n \"express\": \"3.0\"\n }\n}\n```\n\n```js\n// app.js\nvar express = require('express')\n , path = require('path')\n , app = express()\n , less = require('less-middleware');\n\napp.configure(function(){\n // ...\n var bootstrapPath = path.join(__dirname, 'node_modules', 'bootstrap');\n app.use(express.bodyParser());\n app.use(express.methodOverride());\n app.use('/img', express['static'](path.join(bootstrapPath, 'img')));\n app.use(app.router);\n app.use(less({\n src : path.join(__dirname, 'assets', 'less'),\n paths : [path.join(bootstrapPath, 'less')],\n dest : path.join(__dirname, 'public', 'stylesheets'),\n prefix : '/stylesheets'\n }));\n app.use(express['static'](path.join(__dirname, 'public')));\n // ...\n});\n\n// ...\n```\n\n```css\n// assets/less/base.less\n\n@import 'bootstrap';\n@import 'responsive';\n\n@bodyBackground: #FAF7EC;\n@navbarBrandColor: #989CAE;\n\n.brand {\n font-family: @monoFontFamily;\n}\n```\n\n### Preprocessing\n\n```js\nvar lessMiddleware = require('less-middleware');\n\nvar app = express();\n\napp.configure(function () {\n // Other configuration here...\n\n app.use(lessMiddleware({\n src: __dirname + '/public',\n preprocessor: function(src, req) {\n if (req.param(\"namespace\")) {\n src = req.param(\"namespace\") + \" { \" + src + \" }\";\n }\n \n return src;\n },\n compress: true\n }));\n\n app.use(express.static(__dirname + '/public'));\n});\n```\n\n## Troubleshooting\n\n### My less never recompiles, even when I use `{force: true}`!\nMake sure you're declaring less-middleware before your static middleware, if you're using the same directory, e.g. (with express):\n```js\napp.use(require('less-middleware')({ src: __dirname + '/public', debug: true }));\napp.use(express.static(path.join(__dirname, 'public')));\n```\nnot\n```js\napp.use(express.static(path.join(__dirname, 'public')));\napp.use(require('less-middleware')({ src: __dirname + '/public', debug: true }));\n```\n\n### IIS\nIf you are hosting your app on IIS you will have to modify your `web.config` file in order to allow NodeJS to serve your CSS static files. IIS will cache your CSS files, bypassing NodeJS static file serving, which in turn does not allow the middleware to recompile your LESS files.\n", + "readmeFilename": "readme.md", + "bugs": { + "url": "https://github.com/emberfeather/less.js-middleware/issues" + }, + "_id": "less-middleware@0.1.15", + "dist": { + "shasum": "850a1459a59699e828eb3a07e08b4a350eda0b46" + }, + "_from": "less-middleware@*", + "_resolved": "https://registry.npmjs.org/less-middleware/-/less-middleware-0.1.15.tgz" +} diff --git a/node_modules/less-middleware/readme.md b/node_modules/less-middleware/readme.md new file mode 100644 index 0000000..6c59d1c --- /dev/null +++ b/node_modules/less-middleware/readme.md @@ -0,0 +1,355 @@ +## Installation + + sudo npm install less-middleware + +## Options + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

From this shared root, you would specify a URI style path to the appropriate source and destination directories: + +```js +var lessMiddleware = require('less-middleware') + , path = require('path') + , pubDir = path.join(__dirname, 'public') + , app = express(); + +app.configure(function() { + app.use(lessMiddleware({ + dest: '/css', // should be the URI to your css directory from the location bar in your browser + src: '/less', // or '../less' if the less directory is outside of /public + root: pubDir, + compress: true + })); + + app.use(express.static(pubDir)); +}); +``` + +This will allow any file under the /less directory, including subdirectories, to be compiled into an identical directory structure under /css. + +### Express - Using a temp directory for `dest` + +Since less middleware relies on static content to be served by express.static, using temp directories just requires that you inform express about where generated files are built: + +```js +var lessMiddleware = require('less-middleware'), + os = require('os'); + +var app = express(); + +app.configure(function () { + // Other configuration here... + + var tmpDir = os.tmpDir(); + app.use(lessMiddleware({ + src: __dirname + '/public/stylesheets', + dest: tmpDir, + compress: true + })); + + app.use(express.static(__dirname + '/public')); + app.use(express.static(tmpDir)); +}); +``` + +Using a temp directory is useful for read-only file systems, such as a Heroku deployment. By using a temp directory the css files can still be written and served. + +### Importing less + +By default the directory in which the compiled files live in is already set as an import directive: + +```css +// file1.less + +@import 'file2.less'; + +body { + color: @bodyColor; +} +``` + +```css +// file2.less + +@bodyColor: #333333; +``` + +However, you can use the `paths` option if you need to specify other directories in which to search for importable less files. + +```js +var less = require('less-middleware'), + path = require('path'); + + lessMiddleware({ + src: path.join(__dirname, 'public'), + paths: [path.join(__dirname, 'module', 'less')] + }); +``` + +```css +// public/base.css + +@import 'colors'; + +body { + color: @bodyColor; +} +``` + +```css +// module/less/colors.less + +@bodyColor: #333333; +``` + +### Using bootstrap + +Here's an example on how to use Twitter's bootstrap within an Express.js set-up: + +```js +// package.json +{ + "name": "my-module", + // ... + "dependencies": { + "less-middleware": "*", + "bootstrap": "git+https://github.com/twitter/bootstrap.git#v2.2.2", + "express": "3.0" + } +} +``` + +```js +// app.js +var express = require('express') + , path = require('path') + , app = express() + , less = require('less-middleware'); + +app.configure(function(){ + // ... + var bootstrapPath = path.join(__dirname, 'node_modules', 'bootstrap'); + app.use(express.bodyParser()); + app.use(express.methodOverride()); + app.use('/img', express['static'](path.join(bootstrapPath, 'img'))); + app.use(app.router); + app.use(less({ + src : path.join(__dirname, 'assets', 'less'), + paths : [path.join(bootstrapPath, 'less')], + dest : path.join(__dirname, 'public', 'stylesheets'), + prefix : '/stylesheets' + })); + app.use(express['static'](path.join(__dirname, 'public'))); + // ... +}); + +// ... +``` + +```css +// assets/less/base.less + +@import 'bootstrap'; +@import 'responsive'; + +@bodyBackground: #FAF7EC; +@navbarBrandColor: #989CAE; + +.brand { + font-family: @monoFontFamily; +} +``` + +### Preprocessing + +```js +var lessMiddleware = require('less-middleware'); + +var app = express(); + +app.configure(function () { + // Other configuration here... + + app.use(lessMiddleware({ + src: __dirname + '/public', + preprocessor: function(src, req) { + if (req.param("namespace")) { + src = req.param("namespace") + " { " + src + " }"; + } + + return src; + }, + compress: true + })); + + app.use(express.static(__dirname + '/public')); +}); +``` + +## Troubleshooting + +### My less never recompiles, even when I use `{force: true}`! +Make sure you're declaring less-middleware before your static middleware, if you're using the same directory, e.g. (with express): +```js +app.use(require('less-middleware')({ src: __dirname + '/public', debug: true })); +app.use(express.static(path.join(__dirname, 'public'))); +``` +not +```js +app.use(express.static(path.join(__dirname, 'public'))); +app.use(require('less-middleware')({ src: __dirname + '/public', debug: true })); +``` + +### IIS +If you are hosting your app on IIS you will have to modify your `web.config` file in order to allow NodeJS to serve your CSS static files. IIS will cache your CSS files, bypassing NodeJS static file serving, which in turn does not allow the middleware to recompile your LESS files. diff --git a/node_modules/tincanjs/.npmignore b/node_modules/tincanjs/.npmignore new file mode 100644 index 0000000..9638ab5 --- /dev/null +++ b/node_modules/tincanjs/.npmignore @@ -0,0 +1,10 @@ +*.tgz +src +test +doc +vendor +build.js +build/.empty +.travis.yml +yuidoc.json +bower.json diff --git a/node_modules/tincanjs/LICENSE b/node_modules/tincanjs/LICENSE new file mode 100644 index 0000000..d645695 --- /dev/null +++ b/node_modules/tincanjs/LICENSE @@ -0,0 +1,202 @@ + + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ + + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION + + 1.

XMLHttpRequest Emulation for node.js\n\nThis is an [npm](https://npmjs.org/) package that implements the\n[W3C XMLHttpRequest](http://www.w3.org/TR/XMLHttpRequest/) specification on top\nof the [node.js](http://nodejs.org/) APIs.\n\n\n## Supported Platforms\n\nThis library is tested against the following platforms.\n\n* [node.js](http://nodejs.org/) 0.6\n* [node.js](http://nodejs.org/) 0.8\n* [node.js](http://nodejs.org/) 0.10\n* [node.js](http://nodejs.org/) 0.11\n\nKeep in mind that the versions above are not hard requirements.\n\n\n## Installation and Usage\n\nThe preferred installation method is to add the library to the `dependencies`\nsection in your `package.json`.\n\n```json\n{\n \"dependencies\": {\n \"xhr2\": \"*\"\n }\n}\n```\n\nAlternatively, `npm` can be used to install the library directly.\n\n```bash\nnpm install xhr2\n```\n\nOnce the library is installed, `require`-ing it returns the `XMLHttpRequest`\nconstructor.\n\n```javascript\nvar XMLHttpRequest = require('xhr2');\n```\n\nThe other objects that are usually defined in an XHR environment are hanging\noff of `XMLHttpRequest`.\n\n```javascript\nvar XMLHttpRequestUpload = XMLHttpRequest.XMLHttpRequestUpload;\n```\n\nMDN (the Mozilla Developer Network) has a\n[great intro to XMLHttpRequest](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest/Using_XMLHttpRequest).\n\nThis library's [CoffeeDocs](http://coffeedoc.info/github/pwnall/node-xhr2/) can\nbe used as quick reference to the XMLHttpRequest specification parts that were\nimplemented.\n\n\n## Features\n\nThe following standard features are implemented.\n\n* `http` and `https` URI protocols\n* Basic authentication according to the XMLHttpRequest specification\n* request and response header management\n* `send()` accepts the following data types: String, ArrayBufferView,\n ArrayBuffer (deprecated in the standard)\n* `responseType` values: `text`, `json`, `arraybuffer`\n* `readystatechange` and download progress events\n* `overrideMimeType()`\n* `abort()`\n* `timeout`\n* automated redirection following\n\nThe following node.js extensions are implemented.\n\n* `send()` accepts a node.js Buffer\n* Setting `responseType` to `buffer` produces a node.js Buffer\n* `nodejsSet` does XHR network configuration that is not exposed in browsers,\n for security reasons\n\nThe following standard features are not implemented.\n\n* FormData\n* Blob\n* `file://` URIs\n* `data:` URIs\n* upload progress events\n* synchronous operation\n* Same-origin policy checks and CORS\n* cookie processing\n\n\n## Versioning\n\nThe library aims to implement the\n[W3C XMLHttpRequest](http://www.w3.org/TR/XMLHttpRequest/) specification, so\nthe library's API will always be a (hopefully growing) subset of the API in the\nspecification.\n\n\n## Development\n\nThe following commands will get the source tree in a `node-xhr2/` directory and\nbuild the library.\n\n```bash\ngit clone git://github.com/pwnall/node-xhr2.git\ncd node-xhr2\nnpm install\nnpm pack\n```\n\nInstalling CoffeeScript globally will let you type `cake` instead of\n`node_modules/.bin/cake`\n\n```bash\nnpm install -g coffee-script\n```\n\nThe library comes with unit tests that exercise the XMLHttpRequest API.\n\n```bash\ncake test\n```\n\nThe tests themselves can be tested by running them in a browser environment,\nwhere a different XMLHttpRequest implementation is available. Both Google\nChrome and Firefox deviate from the specification in small ways, so it's best\nto run the tests in both browsers and mentally compute an intersection of the\nfailing tests.\n\n```bash\ncake webtest\nBROWSER=firefox cake webtest\n```\n\n\n## Copyright and License\n\nThe library is Copyright (c) 2013 Victor Costan, and distributed under the MIT\nLicense.\n", + "readmeFilename": "README.md", + "_id": "xhr2@0.0.7", + "dist": { + "shasum": "53421690d6a77dab09f3233b8e0378b1a139d9b7" + }, + "_from": "xhr2@0.0.7", + "_resolved": "https://registry.npmjs.org/xhr2/-/xhr2-0.0.7.tgz" +} diff --git a/node_modules/tincanjs/node_modules/xhr2/src/000-xml_http_request_event_target.coffee b/node_modules/tincanjs/node_modules/xhr2/src/000-xml_http_request_event_target.coffee new file mode 100644 index 0000000..61a64cc --- /dev/null +++ b/node_modules/tincanjs/node_modules/xhr2/src/000-xml_http_request_event_target.coffee @@ -0,0 +1,88 @@ +# This file's name is set up in such a way that it will always show up first in +# the list of files given to coffee --join, so that the other files can assume +# that XMLHttpRequestEventTarget was already defined. + + +# The DOM EventTarget subclass used by XMLHttpRequest. +# +# @see http://www.w3.org/TR/XMLHttpRequest/#xmlhttprequesteventtarget +class XMLHttpRequestEventTarget + #

IE 6+ are\nsupported for non-CORS (because they don't support it).\n\nInclude *one* of build/tincan-min.js or build/tincan.js as follows:\n\n \n\nNode.js Usage\n-------------\n\nTinCanJS is available via `npm`.\n\nThe `Environment/Node.js` wrapper used in this version has a dependency on the 'xhr2' module\nwhich is also available via `npm`.
