On changes to the content of the above editor, a (crude) script
+tries to auto-detect the language used, and switches the editor to
+either JavaScript or Scheme mode based on that.
The emacs keybindings are enabled by
+including keymap/emacs.js and setting
+the keyMap option to "emacs". Because
+CodeMirror's internal API is quite different from Emacs, they are only
+a loose approximation of actual emacs bindings, though.
+
+
Also note that a lot of browsers disallow certain keys from being
+captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the
+result that idiomatic use of Emacs keys will constantly close your tab
+or open a new window.
Select a piece of code and click one of the links below to apply automatic formatting to the selected text or comment/uncomment the selected text. Note that the formatting behavior depends on the current block's mode.

If this is a function, it will be called for each token with

The vim keybindings are enabled by

+the keyMap option to "vim". Because
+CodeMirror's internal API is quite different from Vim, they are only
+a loose approximation of actual vim bindings, though.
Tabs inside the editor are spans with the

+an :after pseudo-class CSS hack that will not work on old
+browsers. You can use a more conservative technique like a background
+image as an alternative.

+/* (Re-) Implementing A Syntax-
+ Highlighting Editor in JavaScript */
+
+
+
+
+
+ Topic: JavaScript, code editor implementation
+ Author: Marijn Haverbeke
+ Date: March 2nd 2011 (updated November 13th 2011)
+
+
+
This is a followup to
+my Brutal Odyssey to the
+Dark Side of the DOM Tree story. That one describes the
+mind-bending process of implementing (what would become) CodeMirror 1.
+This one describes the internals of CodeMirror 2, a complete rewrite
+and rethink of the old code base. I wanted to give this piece another
+Hunter Thompson copycat subtitle, but somehow that would be out of
+place—the process this time around was one of straightforward
+engineering, requiring no serious mind-bending whatsoever.
+
+
So, what is wrong with CodeMirror 1? I'd estimate, by mailing list
+activity and general search-engine presence, that it has been
+integrated into about a thousand systems by now. The most prominent
+one, since a few weeks,
+being Google
+code's project hosting. It works, and it's being used widely.
+
+
Still, I did not start replacing it because I was bored. CodeMirror
+1 was heavily reliant on designMode
+or contentEditable (depending on the browser). Neither of
+these are well specified (HTML5 tries
+to specify
+their basics), and, more importantly, they tend to be one of the more
+obscure and buggy areas of browser functionality—CodeMirror, by using
+this functionality in a non-typical way, was constantly running up
+against browser bugs. WebKit wouldn't show an empty line at the end of
+the document, and in some releases would suddenly get unbearably slow.
+Firefox would show the cursor in the wrong place. Internet Explorer
+would insist on linkifying everything that looked like a URL or email
+address, a behaviour that can't be turned off. Some bugs I managed to
+work around (which was often a frustrating, painful process), others,
+such as the Firefox cursor placement, I gave up on, and had to tell
+user after user that they were known problems, but not something I
+could help.
+
+
Also, there is the fact that designMode (which seemed
+to be less buggy than contentEditable in Webkit and
+Firefox, and was thus used by CodeMirror 1 in those browsers) requires
+a frame. Frames are another tricky area. It takes some effort to
+prevent getting tripped up by domain restrictions, they don't
+initialize synchronously, behave strangely in response to the back
+button, and, on several browsers, can't be moved around the DOM
+without having them re-initialize. They did provide a very nice way to
+namespace the library, though—CodeMirror 1 could freely pollute the
+namespace inside the frame.
+
+
Finally, working with an editable document means working with
+selection in arbitrary DOM structures. Internet Explorer (8 and
+before) has an utterly different (and awkward) selection API than all
+of the other browsers, and even among the different implementations of
+document.selection, details about how exactly a selection
+is represented vary quite a bit. Add to that the fact that Opera's
+selection support tended to be very buggy until recently, and you can
+imagine why CodeMirror 1 contains 700 lines of selection-handling
+code.
+
+
And that brings us to the main issue with the CodeMirror 1
+code base: The proportion of browser-bug-workarounds to real
+application code was getting dangerously high. By building on top of a
+few dodgy features, I put the system in a vulnerable position—any
+incompatibility and bugginess in these features, I had to paper over
+with my own code. Not only did I have to do some serious stunt-work to
+get it to work on older browsers (as detailed in the
+previous story), things
+also kept breaking in newly released versions, requiring me to come up
+with new scary hacks in order to keep up. This was starting
+to lose its appeal.
+
+
General Approach
+
+
What CodeMirror 2 does is try to sidestep most of the hairy hacks
+that came up in version 1. I owe a lot to the
+ACE editor for inspiration on how to
+approach this.
+
+
I absolutely did not want to be completely reliant on key events to
+generate my input. Every JavaScript programmer knows that key event
+information is horrible and incomplete. Some people (most awesomely
+Mihai Bazon with Ymacs) have been able
+to build more or less functioning editors by directly reading key
+events, but it takes a lot of work (the kind of never-ending, fragile
+work I described earlier), and will never be able to properly support
+things like multi-keystoke international character
+input. [see below for caveat]
+
+
So what I do is focus a hidden textarea, and let the browser
+believe that the user is typing into that. What we show to the user is
+a DOM structure we built to represent his document. If this is updated
+quickly enough, and shows some kind of believable cursor, it feels
+like a real text-input control.
+
+
Another big win is that this DOM representation does not have to
+span the whole document. Some CodeMirror 1 users insisted that they
+needed to put a 30 thousand line XML document into CodeMirror. Putting
+all that into the DOM takes a while, especially since, for some
+reason, an editable DOM tree is slower than a normal one on most
+browsers. If we have full control over what we show, we must only
+ensure that the visible part of the document has been added, and can
+do the rest only when needed. (Fortunately, the onscroll
+event works almost the same on all browsers, and lends itself well to
+displaying things only as they are scrolled into view.)
+
+
Input
+
+
ACE uses its hidden textarea only as a text input shim, and does
+all cursor movement and things like text deletion itself by directly
+handling key events. CodeMirror's way is to let the browser do its
+thing as much as possible, and not, for example, define its own set of
+key bindings. One way to do this would have been to have the whole
+document inside the hidden textarea, and after each key event update
+the display DOM to reflect what's in that textarea.
+
+
That'd be simple, but it is not realistic. For even medium-sized
+document the editor would be constantly munging huge strings, and get
+terribly slow. What CodeMirror 2 does is put the current selection,
+along with an extra line on the top and on the bottom, into the
+textarea.
+
+
This means that the arrow keys (and their ctrl-variations), home,
+end, etcetera, do not have to be handled specially. We just read the
+cursor position in the textarea, and update our cursor to match it.
+Also, copy and paste work pretty much for free, and people get their
+native key bindings, without any special work on my part. For example,
+I have emacs key bindings configured for Chrome and Firefox. There is
+no way for a script to detect this. [no longer the case]
+
+
Of course, since only a small part of the document sits in the
+textarea, keys like page up and ctrl-end won't do the right thing.
+CodeMirror is catching those events and handling them itself.
+
+
Selection
+
+
Getting and setting the selection range of a textarea in modern
+browsers is trivial—you just use the selectionStart
+and selectionEnd properties. On IE you have to do some
+insane stuff with temporary ranges and compensating for the fact that
+moving the selection by a 'character' will treat \r\n as a single
+character, but even there it is possible to build functions that
+reliably set and get the selection range.
+
+
But consider this typical case: When I'm somewhere in my document,
+press shift, and press the up arrow, something gets selected. Then, if
+I, still holding shift, press the up arrow again, the top of my
+selection is adjusted. The selection remembers where its head
+and its anchor are, and moves the head when we shift-move.
+This is a generally accepted property of selections, and done right by
+every editing component built in the past twenty years.
+
+
But not something that the browser selection APIs expose.
+
+
Great. So when someone creates an 'upside-down' selection, the next
+time CodeMirror has to update the textarea, it'll re-create the
+selection as an 'upside-up' selection, with the anchor at the top, and
+the next cursor motion will behave in an unexpected way—our second
+up-arrow press in the example above will not do anything, since it is
+interpreted in exactly the same way as the first.
+
+
No problem. We'll just, ehm, detect that the selection is
+upside-down (you can tell by the way it was created), and then, when
+an upside-down selection is present, and a cursor-moving key is
+pressed in combination with shift, we quickly collapse the selection
+in the textarea to its start, allow the key to take effect, and then
+combine its new head with its old anchor to get the real
+selection.
+
+
In short, scary hacks could not be avoided entirely in CodeMirror
+2.
+
+
And, the observant reader might ask, how do you even know that a
+key combo is a cursor-moving combo, if you claim you support any
+native key bindings? Well, we don't, but we can learn. The editor
+keeps a set known cursor-movement combos (initialized to the
+predictable defaults), and updates this set when it observes that
+pressing a certain key had (only) the effect of moving the cursor.
+This, of course, doesn't work if the first time the key is used was
+for extending an inverted selection, but it works most of the
+time.
+
+
Intelligent Updating
+
+
One thing that always comes up when you have a complicated internal
+state that's reflected in some user-visible external representation
+(in this case, the displayed code and the textarea's content) is
+keeping the two in sync. The naive way is to just update the display
+every time you change your state, but this is not only error prone
+(you'll forget), it also easily leads to duplicate work on big,
+composite operations. Then you start passing around flags indicating
+whether the display should be updated in an attempt to be efficient
+again and, well, at that point you might as well give up completely.
+
+
I did go down that road, but then switched to a much simpler model:
+simply keep track of all the things that have been changed during an
+action, and then, only at the end, use this information to update the
+user-visible display.
+
+
CodeMirror uses a concept of operations, which start by
+calling a specific set-up function that clears the state and end by
+calling another function that reads this state and does the required
+updating. Most event handlers, and all the user-visible methods that
+change state are wrapped like this. There's a method
+called operation that accepts a function, and returns
+another function that wraps the given function as an operation.
+
+
It's trivial to extend this (as CodeMirror does) to detect nesting,
+and, when an operation is started inside an operation, simply
+increment the nesting count, and only do the updating when this count
+reaches zero again.
+
+
If we have a set of changed ranges and know the currently shown
+range, we can (with some awkward code to deal with the fact that
+changes can add and remove lines, so we're dealing with a changing
+coordinate system) construct a map of the ranges that were left
+intact. We can then compare this map with the part of the document
+that's currently visible (based on scroll offset and editor height) to
+determine whether something needs to be updated.
+
+
CodeMirror uses two update algorithms—a full refresh, where it just
+discards the whole part of the DOM that contains the edited text and
+rebuilds it, and a patch algorithm, where it uses the information
+about changed and intact ranges to update only the out-of-date parts
+of the DOM. When more than 30 percent (which is the current heuristic,
+might change) of the lines need to be updated, the full refresh is
+chosen (since it's faster to do than painstakingly finding and
+updating all the changed lines), in the other case it does the
+patching (so that, if you scroll a line or select another character,
+the whole screen doesn't have to be
+re-rendered). [the full-refresh
+algorithm was dropped, it wasn't really faster than the patching
+one]
+
+
All updating uses innerHTML rather than direct DOM
+manipulation, since that still seems to be by far the fastest way to
+build documents. There's a per-line function that combines the
+highlighting, marking, and
+selection info for that line into a snippet of HTML. The patch updater
+uses this to reset individual lines, the refresh updater builds an
+HTML chunk for the whole visible document at once, and then uses a
+single innerHTML update to do the refresh.
+
+
Parsers can be Simple
+
+
When I wrote CodeMirror 1, I
+thought interruptable
+parsers were a hugely scary and complicated thing, and I used a
+bunch of heavyweight abstractions to keep this supposed complexity
+under control: parsers
+were iterators
+that consumed input from another iterator, and used funny
+closure-resetting tricks to copy and resume themselves.
+
+
This made for a rather nice system, in that parsers formed strictly
+separate modules, and could be composed in predictable ways.
+Unfortunately, it was quite slow (stacking three or four iterators on
+top of each other), and extremely intimidating to people not used to a
+functional programming style.
+
+
With a few small changes, however, we can keep all those
+advantages, but simplify the API and make the whole thing less
+indirect and inefficient. CodeMirror
+2's mode API uses explicit state
+objects, and makes the parser/tokenizer a function that simply takes a
+state and a character stream abstraction, advances the stream one
+token, and returns the way the token should be styled. This state may
+be copied, optionally in a mode-defined way, in order to be able to
+continue a parse at a given point. Even someone who's never touched a
+lambda in his life can understand this approach. Additionally, far
+fewer objects are allocated in the course of parsing now.
+
+
The biggest speedup comes from the fact that the parsing no longer
+has to touch the DOM though. In CodeMirror 1, on an older browser, you
+could see the parser work its way through the document,
+managing some twenty lines in each 50-millisecond time slice it got. It
+was reading its input from the DOM, and updating the DOM as it went
+along, which any experienced JavaScript programmer will immediately
+spot as a recipe for slowness. In CodeMirror 2, the parser usually
+finishes the whole document in a single 100-millisecond time slice—it
+manages some 1500 lines during that time on Chrome. All it has to do
+is munge strings, so there is no real reason for it to be slow
+anymore.
+
+
What Gives?
+
+
Given all this, what can you expect from CodeMirror 2?
+
+
+
+
Small. the base library is
+some 45k when minified
+now, 17k when gzipped. It's smaller than
+its own logo.
+
+
Lightweight. CodeMirror 2 initializes very
+quickly, and does almost no work when it is not focused. This means
+you can treat it almost like a textarea, have multiple instances on a
+page without trouble.
+
+
Huge document support. Since highlighting is
+really fast, and no DOM structure is being built for non-visible
+content, you don't have to worry about locking up your browser when a
+user enters a megabyte-sized document.
+
+
Extended API. Some things kept coming up in the
+mailing list, such as marking pieces of text or lines, which were
+extremely hard to do with CodeMirror 1. The new version has proper
+support for these built in.
+
+
Tab support. Tabs inside editable documents were,
+for some reason, a no-go. At least six different people announced they
+were going to add tab support to CodeMirror 1, none survived (I mean,
+none delivered a working version). CodeMirror 2 no longer removes tabs
+from your document.
+
+
Sane styling.iframe nodes aren't
+really known for respecting document flow. Now that an editor instance
+is a plain div element, it is much easier to size it to
+fit the surrounding elements. You don't even have to make it scroll if
+you do not want to.
+
+
+
+
On the downside, a CodeMirror 2 instance is not a native
+editable component. Though it does its best to emulate such a
+component as much as possible, there is functionality that browsers
+just do not allow us to hook into. Doing select-all from the context
+menu, for example, is not currently detected by CodeMirror.
+
+
[Updates from November 13th 2011] Recently, I've made
+some changes to the codebase that cause some of the text above to no
+longer be current. I've left the text intact, but added markers at the
+passages that are now inaccurate. The new situation is described
+below.
+
+
Content Representation
+
+
The original implementation of CodeMirror 2 represented the
+document as a flat array of line objects. This worked well—splicing
+arrays will require the part of the array after the splice to be
+moved, but this is basically just a simple memmove of a
+bunch of pointers, so it is cheap even for huge documents.
+
+
However, I recently added line wrapping and code folding (line
+collapsing, basically). Once lines start taking up a non-constant
+amount of vertical space, looking up a line by vertical position
+(which is needed when someone clicks the document, and to determine
+the visible part of the document during scrolling) can only be done
+with a linear scan through the whole array, summing up line heights as
+you go. Seeing how I've been going out of my way to make big documents
+fast, this is not acceptable.
+
+
The new representation is based on a B-tree. The leaves of the tree
+contain arrays of line objects, with a fixed minimum and maximum size,
+and the non-leaf nodes simply hold arrays of child nodes. Each node
+stores both the amount of lines that live below them and the vertical
+space taken up by these lines. This allows the tree to be indexed both
+by line number and by vertical position, and all access has
+logarithmic complexity in relation to the document size.
+
+
I gave line objects and tree nodes parent pointers, to the node
+above them. When a line has to update its height, it can simply walk
+these pointers to the top of the tree, adding or subtracting the
+difference in height from each node it encounters. The parent pointers
+also make it cheaper (in complexity terms, the difference is probably
+tiny in normal-sized documents) to find the current line number when
+given a line object. In the old approach, the whole document array had
+to be searched. Now, we can just walk up the tree and count the sizes
+of the nodes coming before us at each level.
+
+
I chose B-trees, not regular binary trees, mostly because they
+allow for very fast bulk insertions and deletions. When there is a big
+change to a document, it typically involves adding, deleting, or
+replacing a chunk of subsequent lines. In a regular balanced tree, all
+these inserts or deletes would have to be done separately, which could
+be really expensive. In a B-tree, to insert a chunk, you just walk
+down the tree once to find where it should go, insert them all in one
+shot, and then break up the node if needed. This breaking up might
+involve breaking up nodes further up, but only requires a single pass
+back up the tree. For deletion, I'm somewhat lax in keeping things
+balanced—I just collapse nodes into a leaf when their child count goes
+below a given number. This means that there are some weird editing
+patterns that may result in a seriously unbalanced tree, but even such
+an unbalanced tree will perform well, unless you spend a day making
+strangely repeating edits to a really big document.
+
+
Keymaps
+
+
Above, I claimed that directly catching key
+events for things like cursor movement is impractical because it
+requires some browser-specific kludges. I then proceeded to explain
+some awful hacks that were needed to make it
+possible for the selection changes to be detected through the
+textarea. In fact, the second hack is about as bad as the first.
+
+
On top of that, in the presence of user-configurable tab sizes and
+collapsed and wrapped lines, lining up cursor movement in the textarea
+with what's visible on the screen becomes a nightmare. Thus, I've
+decided to move to a model where the textarea's selection is no longer
+depended on.
+
+
So I moved to a model where all cursor movement is handled by my
+own code. This adds support for a goal column, proper interaction of
+cursor movement with collapsed lines, and makes it possible for
+vertical movement to move through wrapped lines properly, instead of
+just treating them like non-wrapped lines.
+
+
The key event handlers now translate the key event into a string,
+something like Ctrl-Home or Shift-Cmd-R, and
+use that string to look up an action to perform. To make keybinding
+customizable, this lookup goes through
+a table, using a scheme that
+allows such tables to be chained together (for example, the default
+Mac bindings fall through to a table named 'emacsy', which defines
+basic Emacs-style bindings like Ctrl-F, and which is also
+used by the custom Emacs bindings).
+
+
A new
+option extraKeys
+allows ad-hoc keybindings to be defined in a much nicer way than what
+was possible with the
+old onKeyEvent
+callback. You simply provide an object mapping key identifiers to
+functions, instead of painstakingly looking at raw key events.
+
+
Built-in commands map to strings, rather than functions, for
+example "goLineUp" is the default action bound to the up
+arrow key. This allows new keymaps to refer to them without
+duplicating any code. New commands can be defined by assigning to
+the CodeMirror.commands object, which maps such commands
+to functions.
+
+
The hidden textarea now only holds the current selection, with no
+extra characters around it. This has a nice advantage: polling for
+input becomes much, much faster. If there's a big selection, this text
+does not have to be read from the textarea every time—when we poll,
+just noticing that something is still selected is enough to tell us
+that no new text was typed.
+
+
The reason that cheap polling is important is that many browsers do
+not fire useful events on IME (input method engine) input, which is
+the thing where people inputting a language like Japanese or Chinese
+use multiple keystrokes to create a character or sequence of
+characters. Most modern browsers fire input when the
+composing is finished, but many don't fire anything when the character
+is updated during composition. So we poll, whenever the
+editor is focused, to provide immediate updates of the display.
CodeMirror is a code-editor component that can be embedded in
+ Web pages. The code library provides only the editor
+ component, no accompanying buttons, auto-completion, or other IDE
+ functionality. It does provide a rich API on top of which such
+ functionality can be straightforwardly implemented. See
+ the add-ons included in the distribution,
+ and
+ the CodeMirror
+ UI project, for reusable implementations of extra features.
+
+
CodeMirror works with language-specific modes. Modes are
+ JavaScript programs that help color (and optionally indent) text
+ written in a given language. The distribution comes with a few
+ modes (see the mode/ directory), and it isn't hard
+ to write new ones for other languages.
+
+
Basic Usage
+
+
The easiest way to use CodeMirror is to simply load the script
+ and style sheet found under lib/ in the distribution,
+ plus a mode script from one of the mode/ directories
+ and a theme stylesheet from theme/. (See
+ also the compression helper.) For
+ example:
Having done this, an editor instance can be created like
+ this:
+
+
var myCodeMirror = CodeMirror(document.body);
+
+
The editor will be appended to the document body, will start
+ empty, and will use the mode that we loaded. To have more control
+ over the new editor, a configuration object can be passed
+ to CodeMirror as a second argument:
This will initialize the editor with a piece of code already in
+ it, and explicitly tell it to use the JavaScript mode (which is
+ useful when multiple modes are loaded).
+ See below for a full discussion of the
+ configuration options that CodeMirror accepts.
+
+
In cases where you don't want to append the editor to an
+ element, and need more control over the way it is inserted, the
+ first argument to the CodeMirror function can also
+ be a function that, when given a DOM element, inserts it into the
+ document somewhere. This could be used to, for example, replace a
+ textarea with a real editor:
However, for this use case, which is a common way to use
+ CodeMirror, the library provides a much more powerful
+ shortcut:
+
+
var myCodeMirror = CodeMirror.fromTextArea(myTextArea);
+
+
This will, among other things, ensure that the textarea's value
+ is updated when the form (if it is part of a form) is submitted.
+ See the API reference for a full
+ description of this method.
+
+
Configuration
+
+
Both the CodeMirror function and
+ its fromTextArea method take as second (optional)
+ argument an object containing configuration options. Any option
+ not supplied like this will be taken
+ from CodeMirror.defaults, an object containing the
+ default options. You can update this object to change the defaults
+ on your page.
+
+
Options are not checked in any way, so setting bogus option
+ values is bound to lead to odd errors.
+
+
These are the supported options:
+
+
+
value (string)
+
The starting value of the editor.
+
+
mode (string or object)
+
The mode to use. When not given, this will default to the
+ first mode that was loaded. It may be a string, which either
+ simply names the mode or is
+ a MIME type
+ associated with the mode. Alternatively, it may be an object
+ containing configuration options for the mode, with
+ a name property that names the mode (for
+ example {name: "javascript", json: true}). The demo
+ pages for each mode contain information about what configuration
+ parameters the mode supports. You can ask CodeMirror which modes
+ and MIME types are loaded with
+ the CodeMirror.listModes
+ and CodeMirror.listMIMEs functions.
+
+
theme (string)
+
The theme to style the editor with. You must make sure the
+ CSS file defining the corresponding .cm-s-[name]
+ styles is loaded (see
+ the theme directory in the
+ distribution). The default is "default", for which
+ colors are included in codemirror.css. It is
+ possible to use multiple theming classes at once—for
+ example "foo bar" will assign both
+ the cm-s-foo and the cm-s-bar classes
+ to the editor.
+
+
indentUnit (integer)
+
How many spaces a block (whatever that means in the edited
+ language) should be indented. The default is 2.
+
+
smartIndent (boolean)
+
Whether to use the context-sensitive indentation that the
+ mode provides (or just indent the same as the line before).
+ Defaults to true.
+
+
tabSize (integer)
+
The width of a tab character. Defaults to 4.
+
+
indentWithTabs (boolean)
+
Whether, when indenting, the first N*tabSize
+ spaces should be replaced by N tabs. Default is false.
+
+
electricChars (boolean)
+
Configures whether the editor should re-indent the current
+ line when a character is typed that might change its proper
+ indentation (only works if the mode supports indentation).
+ Default is true.
+
+
keyMap (string)
+
Configures the keymap to use. The default
+ is "default", which is the only keymap defined
+ in codemirror.js itself. Extra keymaps are found in
+ the keymap directory.
+
+
extraKeys (object)
+
Can be used to specify extra keybindings for the editor.
+ When given, should be an object with property names
+ like Ctrl-A, Home,
+ and Ctrl-Alt-Left. See
+ the CodeMirror.keyNames object for the names of all
+ the keys. The values in this object can either be functions,
+ which will be called with the CodeMirror instance when the key
+ is pressed, or strings, which should name commands defined
+ in CodeMirror.commands (not documented properly,
+ but looking at the source and the definition of the built-in
+ keymaps, they should be rather obvious).
+
+
lineWrapping (boolean)
+
Whether CodeMirror should scroll or wrap for long lines.
+ Defaults to false (scroll).
+
+
lineNumbers (boolean)
+
Whether to show line numbers to the left of the editor.
+
+
firstLineNumber (integer)
+
At which number to start counting lines. Default is 1.
+
+
gutter (boolean)
+
Can be used to force a 'gutter' (empty space on the left of
+ the editor) to be shown even when no line numbers are active.
+ This is useful for setting markers.
+
+
fixedGutter (boolean)
+
When enabled (off by default), this will make the gutter
+ stay visible when the document is scrolled horizontally.
+
+
readOnly (boolean)
+
This disables editing of the editor content by the user. If
+ the special value "nocursor" is given (instead of
+ simply true), focusing of the editor is also
+ disallowed.
+
+
onChange (function)
+
When given, this function will be called every time the
+ content of the editor is changed. It will be given the editor
+ instance as first argument, and an {from, to, text, next}
+ object containing information about the changes
+ that occurred as second argument. from
+ and to are the positions (in the pre-change
+ coordinate system) where the change started and
+ ended (for example, it might be {ch:0, line:18} if the
+ position is at line #19, at the first character. text is an
+ array of strings representing the text that replaced the changed range
+ (split by line). If multiple changes happened during a single operation,
+ the object will have a next property pointing to another
+ change object (which may point to another, etc).
+
+
onCursorActivity (function)
+
Will be called when the cursor or selection moves, or any
+ change is made to the editor content.
+
+
onGutterClick (function)
+
When given, will be called whenever the editor gutter (the
+ line-number area) is clicked. Will be given the editor instance
+ as first argument, the (zero-based) number of the line that was
+ clicked as second argument, and the raw mousedown
+ event object as third argument.
+
+
onFocus, onBlur (function)
+
The given functions will be called whenever the editor is
+ focused or unfocused.
+
+
onScroll (function)
+
When given, will be called whenever the editor is
+ scrolled.
+
+
onHighlightComplete (function)
+
Whenever the editor's content has been fully highlighted,
+ this function (if given) will be called. It'll be given a single
+ argument, the editor instance.
+
+
onUpdate (function)
+
Will be called whenever CodeMirror updates its DOM display.
+
+
matchBrackets (boolean)
+
Determines whether brackets are matched whenever the cursor
+ is moved next to a bracket.
+
+
workTime, workDelay (number)
+
Highlighting is done by a pseudo background-thread that will
+ work for workTime milliseconds, and then use
+ timeout to sleep for workDelay milliseconds. The
+ defaults are 200 and 300, you can change these options to make
+ the highlighting more or less aggressive.
+
+
pollInterval (number)
+
Indicates how quickly CodeMirror should poll its input
+ textarea for changes. Most input is captured by events, but some
+ things, like IME input on some browsers, doesn't generate events
+ that allow CodeMirror to properly detect it. Thus, it polls.
+ Default is 100 milliseconds.
+
+
undoDepth (integer)
+
The maximum number of undo levels that the editor stores.
+ Defaults to 40.
+
+
tabindex (integer)
+
The tab
+ index to assign to the editor. If not given, no tab index
+ will be assigned.
+
+
document (DOM document)
+
Use this if you want to display the editor in another DOM.
+ By default it will use the global document
+ object.
+
+
onKeyEvent (function)
+
This provides a rather low-level hook into CodeMirror's key
+ handling. If provided, this function will be called on
+ every keydown, keyup,
+ and keypress event that CodeMirror captures. It
+ will be passed two arguments, the editor instance and the key
+ event. This key event is pretty much the raw key event, except
+ that a stop() method is always added to it. You
+ could feed it to, for example, jQuery.Event to
+ further normalize it. This function can inspect the key
+ event, and handle it if it wants to. It may return true to tell
+ CodeMirror to ignore the event. Be wary that, on some browsers,
+ stopping a keydown does not stop
+ the keypress from firing, whereas on others it
+ does. If you respond to an event, you should probably inspect
+ its type property and only do something when it
+ is keydown (or keypress for actions
+ that need character data).
+
+
+
Customized Styling
+
+
Up to a certain extent, CodeMirror's look can be changed by
+ modifying style sheet files. The style sheets supplied by modes
+ simply provide the colors for that mode, and can be adapted in a
+ very straightforward way. To style the editor itself, it is
+ possible to alter or override the styles defined
+ in codemirror.css.
+
+
Some care must be taken there, since a lot of the rules in this
+ file are necessary to have CodeMirror function properly. Adjusting
+ colors should be safe, of course, and with some care a lot of
+ other things can be changed as well. The CSS classes defined in
+ this file serve the following roles:
+
+
+
CodeMirror
+
The outer element of the editor. This should be used for
+ borders and positioning. Can also be used to set styles that
+ should hold for everything inside the editor (such as font
+ and font size), or to set a background.
+
+
CodeMirror-scroll
+
This determines whether the editor scrolls (overflow:
+ auto + fixed height). By default, it does. Giving
+ this height: auto; overflow: visible; will cause
+ the editor to resize to fit its content.
+
+
CodeMirror-focused
+
Whenever the editor is focused, the top element gets this
+ class. This is used to hide the cursor and give the selection a
+ different color when the editor is not focused.
+
+
CodeMirror-gutter
+
Use this for giving a background or a border to the editor
+ gutter. Don't set any padding here,
+ use CodeMirror-gutter-text for that. By default,
+ the gutter is 'fluid', meaning it will adjust its width to the
+ maximum line number or line marker width. You can also set a
+ fixed width if you want.
+
+
CodeMirror-gutter-text
+
Used to style the actual line numbers. For the numbers to
+ line up, you must make sure that the font in the gutter is the
+ same as the one in the rest of the editor, so you should
+ probably only set font style and size in
+ the CodeMirror class.
+
+
CodeMirror-lines
+
The visible lines. If this has vertical
+ padding, CodeMirror-gutter should have the same
+ padding.
+
+
CodeMirror-cursor
+
The cursor is a block element that is absolutely positioned.
+ You can make it look whichever way you want.
+
+
CodeMirror-selected
+
The selection is represented by span elements
+ with this class.
These are used to style matched (or unmatched) brackets.
+
+
+
The actual lines, as well as the cursor, are represented
+ by pre elements. By default no text styling (such as
+ bold) that might change line height is applied. If you do want
+ such effects, you'll have to give CodeMirror pre a
+ fixed height. Also, you must still take care that character width
+ is constant.
+
+
If your page's style sheets do funky things to
+ all div or pre elements (you probably
+ shouldn't do that), you'll have to define rules to cancel these
+ effects out again for elements under the CodeMirror
+ class.
+
+
Themes are also simply CSS files, which define colors for
+ various syntactic elements. See the files in
+ the theme directory.
+
+
Programming API
+
+
A lot of CodeMirror features are only available through its API.
+ This has the disadvantage that you need to do work to enable them,
+ and the advantage that CodeMirror will fit seamlessly into your
+ application.
+
+
Whenever points in the document are represented, the API uses
+ objects with line and ch properties.
+ Both are zero-based. CodeMirror makes sure to 'clip' any positions
+ passed by client code so that they fit inside the document, so you
+ shouldn't worry too much about sanitizing your coordinates. If you
+ give ch a value of null, or don't
+ specify it, it will be replaced with the length of the specified
+ line.
+
+
+
getValue() → string
+
Get the current editor content.
+
setValue(string)
+
Set the editor content.
+
+
getSelection() → string
+
Get the currently selected code.
+
replaceSelection(string)
+
Replace the selection with the given string.
+
+
focus()
+
Give the editor focus.
+
scrollTo(x, y)
+
Scroll the editor to a given (pixel) position. Both
+ arguments may be left as null
+ or undefined to have no effect.
+
+
setOption(option, value)
+
Change the configuration of the editor. option
+ should the name of an option,
+ and value should be a valid value for that
+ option.
+
getOption(option) → value
+
Retrieves the current value of the given option for this
+ editor instance.
+
+
cursorCoords(start) → object
+
Returns an {x, y, yBot} object containing the
+ coordinates of the cursor relative to the top-left corner of the
+ page. yBot is the coordinate of the bottom of the
+ cursor. start is a boolean indicating whether you
+ want the start or the end of the selection.
+
charCoords(pos) → object
+
Like cursorCoords, but returns the position of
+ an arbitrary characters. pos should be
+ a {line, ch} object.
+
coordsChar(object) → pos
+
Given an {x, y} object (in page coordinates),
+ returns the {line, ch} position that corresponds to
+ it.
+
+
undo()
+
Undo one edit (if any undo events are stored).
+
redo()
+
Redo one undone edit.
+
historySize() → object
+
Returns an object with {undo, redo} properties,
+ both of which hold integers, indicating the amount of stored
+ undo and redo operations.
+
clearHistory()
+
Clears the editor's undo history.
+
+
indentLine(line, dir)
+
Reset the given line's indentation to the indentation
+ prescribed by the mode. If the second argument is given,
+ indentation will be increased (if dir is true) or
+ decreased (if false) by an indent
+ unit instead.
+
+
getTokenAt(pos) → object
+
Retrieves information about the token the current mode found
+ at the given position (a {line, ch} object). The
+ returned object has the following properties:
+
+
start
The character (on the given line) at which the token starts.
+
end
The character at which the token ends.
+
string
The token's string.
+
className
The class the mode assigned
+ to the token. (Can be null when no class was assigned.)
+
state
The mode's state at the end of this token.
+
+
+
markText(from, to, className) → object
+
Can be used to mark a range of text with a specific CSS
+ class name. from and to should
+ be {line, ch} objects. The method will return an
+ object with two methods, clear(), which removes the
+ mark, and find(), which returns a {from,
+ to} (both document positions), indicating the current
+ position of the marked range.
+
+
setBookmark(pos) → object
+
Inserts a bookmark, a handle that follows the text around it
+ as it is being edited, at the given position. A bookmark has two
+ methods find() and clear(). The first
+ returns the current position of the bookmark, if it is still in
+ the document, and the second explicitly removes the
+ bookmark.
+
+
setMarker(line, text, className) → lineHandle
+
Add a gutter marker for the given line. Gutter markers are
+ shown in the line-number area (instead of the number for this
+ line). Both text and className are
+ optional. Setting text to a Unicode character like
+ ● tends to give a nice effect. To put a picture in the gutter,
+ set text to a space and className to
+ something that sets a background image. If you
+ specify text, the given text (which may contain
+ HTML) will, by default, replace the line number for that line.
+ If this is not what you want, you can include the
+ string %N% in the text, which will be replaced by
+ the line number.
+
clearMarker(line)
+
Clears a marker created
+ with setMarker. line can be either a
+ number or a handle returned by setMarker (since a
+ number may now refer to a different line if something was added
+ or deleted).
+
setLineClass(line, className) → lineHandle
+
Set a CSS class name for the given line. line
+ can be a number or a line handle (as returned
+ by setMarker or this function).
+ Pass null to clear the class for a line.
+
hideLine(line) → lineHandle
+
Hide the given line (either by number or by handle). Hidden
+ lines don't show up in the editor, and their numbers are skipped
+ when line numbers are enabled.
+ Deleting a region around them does delete them, and coping a
+ region around will include them in the copied text.
+
showLine(line) → lineHandle
+
The inverse of hideLine—re-shows a previously
+ hidden line, by number or by handle.
+
+
onDeleteLine(line, func)
+
Register a function that should be called when the line is
+ deleted from the document.
+
+
lineInfo(line) → object
+
Returns the line number, text content, and marker status of
+ the given line, which can be either a number or a handle
+ returned by setMarker. The returned object has the
+ structure {line, handle, text, markerText, markerClass}.
+
+
getLineHandle(num) → lineHandle
+
Fetches the line handle for the given line number.
+
+
addWidget(pos, node, scrollIntoView)
+
Puts node, which should be an absolutely
+ positioned DOM node, into the editor, positioned right below the
+ given {line, ch} position.
+ When scrollIntoView is true, the editor will ensure
+ that the entire node is visible (if possible). To remove the
+ widget again, simply use DOM methods (move it somewhere else, or
+ call removeChild on its parent).
+
+
matchBrackets()
+
Force matching-bracket-highlighting to happen.
+
+
lineCount() → number
+
Get the number of lines in the editor.
+
+
getCursor(start) → object
+
start is a boolean indicating whether the start
+ or the end of the selection must be retrieved. If it is not
+ given, the current cursor pos, i.e. the side of the selection
+ that would move if you pressed an arrow key, is chosen.
+ A {line, ch} object will be returned.
+
somethingSelected() → boolean
+
Return true if any text is selected.
+
setCursor(pos)
+
Set the cursor position. You can either pass a
+ single {line, ch} object, or the line and the
+ character as two separate parameters.
+
setSelection(start, end)
+
Set the selection range. start
+ and end should be {line, ch} objects.
+
+
getLine(n) → string
+
Get the content of line n.
+
setLine(n, text)
+
Set the content of line n.
+
removeLine(n)
+
Remove the given line from the document.
+
+
getRange(from, to) → string
+
Get the text between the given points in the editor, which
+ should be {line, ch} objects.
+
replaceRange(string, from, to)
+
Replace the part of the document between from
+ and to with the given string. from
+ and to must be {line, ch}
+ objects. to can be left off to simply insert the
+ string at position from.
+
+
posFromIndex(index) → object
+
Calculates and returns a {line, ch} object for a
+ zero-based index who's value is relative to the start of the
+ editor's text. If the index is out of range of the text then
+ the returned object is clipped to start or end of the text
+ respectively.
CodeMirror internally buffers changes and only updates its
+ DOM structure after it has finished performing some operation.
+ If you need to perform a lot of operations on a CodeMirror
+ instance, you can call this method with a function argument. It
+ will call the function, buffering up all changes, and only doing
+ the expensive update after the function returns. This can be a
+ lot faster. The return value from this method will be the return
+ value of your function.
+
+
refresh()
+
If your code does something to change the size of the editor
+ element (window resizes are already listened for), or unhides
+ it, you should probably follow up by calling this method to
+ ensure CodeMirror is still looking as intended.
+
+
getInputField() → textarea
+
Returns the hiden textarea used to read input.
+
getWrapperElement() → node
+
Returns the DOM node that represents the editor. Remove this
+ from your tree to delete an editor instance.
+
getScrollerElement() → node
+
Returns the DOM node that is responsible for the sizing and
+ the scrolling of the editor. You can change
+ the height and width styles of this
+ element to resize an editor. (You might have to call
+ the refresh method
+ afterwards.)
+
getGutterElement() → node
+
Fetches the DOM node that represents the editor gutter.
+
+
getStateAfter(line) → state
+
Returns the mode's parser state, if any, at the end of the
+ given line number. If no line number is given, the state at the
+ end of the document is returned. This can be useful for storing
+ parsing errors in the state, or getting other kinds of
+ contextual information for a line.
+
+
+
Finally, the CodeMirror object
+ itself has a method fromTextArea. This takes a
+ textarea DOM node as first argument and an optional configuration
+ object as second. It will replace the textarea with a CodeMirror
+ instance, and wire up the form of that textarea (if any) to make
+ sure the editor contents are put into the textarea when the form
+ is submitted. A CodeMirror instance created this way has two
+ additional methods:
+
+
+
save()
+
Copy the content of the editor into the textarea.
+
+
toTextArea()
+
Remove the editor, and restore the original textarea (with
+ the editor's current content).
+
+
getTextArea() → textarea
+
Returns the textarea that the instance was based on.
+
+
+
If you want to define extra methods in terms
+ of the CodeMirror API, it is possible to
+ use CodeMirror.defineExtension(name, value). This
+ will cause the given value (usually a method) to be added to all
+ CodeMirror instances created from then on.
+
+
Add-ons
+
+
The lib/util directory in the distribution
+ contains a number of reusable components that implement extra
+ editor functionality. In brief, they are:
Provides a very simple way to query users for text input.
+ Adds an openDialog method to CodeMirror instances,
+ which can be called with an HTML fragment that provides the
+ prompt (should include an input tag), and a
+ callback function that is called when text has been entered.
+ Depends on lib/util/dialog.css.
Adds the getSearchCursor(query, start, caseFold) →
+ cursor method to CodeMirror instances, which can be used
+ to implement search/replace functionality. query
+ can be a regular expression or a string (only strings will match
+ across lines—if they contain newlines). start
+ provides the starting position of the search. It can be
+ a {line, ch} object, or can be left off to default
+ to the start of the document. caseFold is only
+ relevant when matching a string. It will cause the search to be
+ case-insensitive. A search cursor has the following methods:
+
+
findNext(), findPrevious() → boolean
+
Search forward or backward from the current position.
+ The return value indicates whether a match was found. If
+ matching a regular expression, the return value will be the
+ array returned by the match method, in case you
+ want to extract matched groups.
+
from(), to() → object
+
These are only valid when the last call
+ to findNext or findPrevious did
+ not return false. They will return {line, ch}
+ objects pointing at the start and end of the match.
+
replace(text)
+
Replaces the currently found match with the given text
+ and adjusts the cursor position to reflect the
+ replacement.
Implements the search commands. CodeMirror has keys bound to
+ these by default, but will not do anything with them unless an
+ implementation is provided. Depends
+ on searchcursor.js, and will make use
+ of openDialog when
+ available to make prompting for search queries less ugly.
Helps with code folding. See the
+ demo for an example.
+ Call CodeMirror.newFoldFunction with a range-finder
+ helper function to create a function that will, when applied to
+ a CodeMirror instance and a line number, attempt to fold or
+ unfold the block starting at the given line. A range-finder is a
+ language-specific functoin that also takes an instance and a
+ line number, and returns an end line for the block, or null if
+ no block is started on that line. This file
+ provides CodeMirror.braceRangeFinder, which finds
+ blocks in brace languages (JavaScript, C, Java, etc).
Provides a framework for showing autocompletion hints.
+ Defines CodeMirror.simpleHint, which takes a
+ CodeMirror instance and a hinting function, and pops up a widget
+ that allows the user to select a completion. Hinting functions
+ are function that take an editor instance, and return
+ a {list, from, to} object, where list
+ is an array of strings (the completions), and from
+ and to give the start and end of the token that is
+ being completed. Depends
+ on lib/util/simple-hint.css.
Defines CodeMirror.javaScriptHint, which is a
+ simple hinting function for the JavaScript mode.
+
+
+
Writing CodeMirror Modes
+
+
Modes typically consist of a single JavaScript file. This file
+ defines, in the simplest case, a lexer (tokenizer) for your
+ language—a function that takes a character stream as input,
+ advances it past a token, and returns a style for that token. More
+ advanced modes can also handle indentation for the language.
+
+
The mode script should
+ call CodeMirror.defineMode to register itself with
+ CodeMirror. This function takes two arguments. The first should be
+ the name of the mode, for which you should use a lowercase string,
+ preferably one that is also the name of the files that define the
+ mode (i.e. "xml" is defined xml.js). The
+ second argument should be a function that, given a CodeMirror
+ configuration object (the thing passed to
+ the CodeMirror function) and an optional mode
+ configuration object (as in
+ the mode option), returns
+ a mode object.
+
+
Typically, you should use this second argument
+ to defineMode as your module scope function (modes
+ should not leak anything into the global scope!), i.e. write your
+ whole mode inside this function.
+
+
The main responsibility of a mode script is parsing
+ the content of the editor. Depending on the language and the
+ amount of functionality desired, this can be done in really easy
+ or extremely complicated ways. Some parsers can be stateless,
+ meaning that they look at one element (token) of the code
+ at a time, with no memory of what came before. Most, however, will
+ need to remember something. This is done by using a state
+ object, which is an object that is always passed when
+ reading a token, and which can be mutated by the tokenizer.
+
+
Modes that use a state must define
+ a startState method on their mode object. This is a
+ function of no arguments that produces a state object to be used
+ at the start of a document.
+
+
The most important part of a mode object is
+ its token(stream, state) method. All modes must
+ define this method. It should read one token from the stream it is
+ given as an argument, optionally update its state, and return a
+ style string, or null for tokens that do not have to
+ be styled. For your styles, you can either use the 'standard' ones
+ defined in the themes (without the cm- prefix), or
+ define your own (as the diff
+ mode does) and have people include a custom CSS file for your
+ mode.
+
+
The stream object encapsulates a line of code
+ (tokens may never span lines) and our current position in that
+ line. It has the following API:
+
+
+
eol() → boolean
+
Returns true only if the stream is at the end of the
+ line.
+
sol() → boolean
+
Returns true only if the stream is at the start of the
+ line.
+
+
peek() → character
+
Returns the next character in the stream without advancing
+ it. Will return undefined at the end of the
+ line.
+
next() → character
+
Returns the next character in the stream and advances it.
+ Also returns undefined when no more characters are
+ available.
+
+
eat(match) → character
+
match can be a character, a regular expression,
+ or a function that takes a character and returns a boolean. If
+ the next character in the stream 'matches' the given argument,
+ it is consumed and returned. Otherwise, undefined
+ is returned.
+
eatWhile(match) → boolean
+
Repeatedly calls eat with the given argument,
+ until it fails. Returns true if any characters were eaten.
+
eatSpace() → boolean
+
Shortcut for eatWhile when matching
+ white-space.
+
skipToEnd()
+
Moves the position to the end of the line.
+
skipTo(ch) → boolean
+
Skips to the next occurrence of the given character, if
+ found on the current line (doesn't advance the stream if the
+ character does not occur on the line). Returns true if the
+ character was found.
+
match(pattern, consume, caseFold) → boolean
+
Act like a
+ multi-character eat—if consume is true
+ or not given—or a look-ahead that doesn't update the stream
+ position—if it is false. pattern can be either a
+ string or a regular expression starting with ^.
+ When it is a string, caseFold can be set to true to
+ make the match case-insensitive. When successfully matching a
+ regular expression, the returned value will be the array
+ returned by match, in case you need to extract
+ matched groups.
+
+
backUp(n)
+
Backs up the stream n characters. Backing it up
+ further than the start of the current token will cause things to
+ break, so be careful.
+
column() → integer
+
Returns the column (taking into account tabs) at which the
+ current token starts. Can be used to find out whether a token
+ starts a new line.
+
indentation() → integer
+
Tells you how far the current line has been indented, in
+ spaces. Corrects for tab characters.
+
+
current() → string
+
Get the string between the start of the current token and
+ the current stream position.
+
+
+
By default, blank lines are simply skipped when
+ tokenizing a document. For languages that have significant blank
+ lines, you can define a blankLine(state) method on
+ your mode that will get called whenever a blank line is passed
+ over, so that it can update the parser state.
+
+
Because state object are mutated, and CodeMirror
+ needs to keep valid versions of a state around so that it can
+ restart a parse at any line, copies must be made of state objects.
+ The default algorithm used is that a new state object is created,
+ which gets all the properties of the old object. Any properties
+ which hold arrays get a copy of these arrays (since arrays tend to
+ be used as mutable stacks). When this is not correct, for example
+ because a mode mutates non-array properties of its state object, a
+ mode object should define a copyState method,
+ which is given a state and should return a safe copy of that
+ state.
+
+
By default, CodeMirror will stop re-parsing
+ a document as soon as it encounters a few lines that were
+ highlighted the same in the old parse as in the new one. It is
+ possible to provide an explicit way to test whether a state is
+ equivalent to another one, which CodeMirror will use (instead of
+ the unchanged-lines heuristic) to decide when to stop
+ highlighting. You do this by providing
+ a compareStates method on your mode object, which
+ takes two state arguments and returns a boolean indicating whether
+ they are equivalent. See the XML mode, which uses this to provide
+ reliable highlighting of bad closing tags, as an example.
+
+
If you want your mode to provide smart indentation
+ (though the indentLine
+ method and the indentAuto
+ and newlineAndIndent commands, which keys can be
+ bound to), you must define
+ an indent(state, textAfter) method on your mode
+ object.
+
+
The indentation method should inspect the given state object,
+ and optionally the textAfter string, which contains
+ the text on the line that is being indented, and return an
+ integer, the amount of spaces to indent. It should usually take
+ the indentUnit
+ option into account.
+
+
Finally, a mode may define
+ an electricChars property, which should hold a string
+ containing all the characters that should trigger the behaviour
+ described for
+ the electricChars
+ option.
+
+
So, to summarize, a mode must provide
+ a token method, and it may
+ provide startState, copyState,
+ compareStates, and indent methods. For
+ an example of a trivial mode, see
+ the diff mode, for a more involved
+ example, see the C-like
+ mode.
+
+
Sometimes, it is useful for modes to nest—to have one
+ mode delegate work to another mode. An example of this kind of
+ mode is the mixed-mode HTML
+ mode. To implement such nesting, it is usually necessary to
+ create mode objects and copy states yourself. To create a mode
+ object, there are CodeMirror.getMode(options,
+ parserConfig), where the first argument is a configuration
+ object as passed to the mode constructor function, and the second
+ argument is a mode specification as in
+ the mode option. To copy a
+ state object, call CodeMirror.copyState(mode, state),
+ where mode is the mode that created the given
+ state.
+
+
To make indentation work properly in a nested parser, it is
+ advisable to give the startState method of modes that
+ are intended to be nested an optional argument that provides the
+ base indentation for the block of code. The JavaScript and CSS
+ parser do this, for example, to allow JavaScript and CSS code
+ inside the mixed-mode HTML mode to be properly indented.
+
+
Finally, it is possible to associate your mode, or a certain
+ configuration of your mode, with
+ a MIME type. For
+ example, the JavaScript mode associates itself
+ with text/javascript, and its JSON variant
+ with application/json. To do this,
+ call CodeMirror.defineMIME(mime, modeSpec),
+ where modeSpec can be a string or object specifying a
+ mode, as in the mode
+ option.
CodeMirror 2 is a complete rewrite that's
+ faster, smaller, simpler to use, and less dependent on browser
+ quirks. See this
+ and this
+ for more information.
+
+
More consistent page-up/page-down behaviour
+ across browsers. Fix some issues with hidden editors looping forever
+ when line-numbers were enabled. Make PHP parser parse
+ "\\" correctly. Have jumpToLine work on
+ line handles, and add cursorLine function to fetch the
+ line handle where the cursor currently is. Add new
+ setStylesheet function to switch style-sheets in a
+ running editor.
Adds removeLine method to API.
+ Introduces the PLSQL parser.
+ Marks XML errors by adding (rather than replacing) a CSS class, so
+ that they can be disabled by modifying their style. Fixes several
+ selection bugs, and a number of small glitches.
Add support for having both line-wrapping and
+ line-numbers turned on, make paren-highlighting style customisable
+ (markParen and unmarkParen config
+ options), work around a selection bug that Opera
+ reintroduced in version 10.
Solves some issues introduced by the
+ paste-handling changes from the previous release. Adds
+ setSpellcheck, setTextWrapping,
+ setIndentUnit, setUndoDepth,
+ setTabMode, and setLineNumbers to
+ customise a running editor. Introduces an SQL parser. Fixes a few small
+ problems in the Python
+ parser. And, as usual, add workarounds for various newly discovered
+ browser incompatibilities.
Overhaul of paste-handling (less fragile), fixes for several
+serious IE8 issues (cursor jumping, end-of-document bugs) and a number
+of small problems.
Introduces Python
+and Lua parsers. Add
+setParser (on-the-fly mode changing) and
+clearHistory methods. Make parsing passes time-based
+instead of lines-based (see the passTime option).
So you found a problem in CodeMirror. By all means, report it! Bug
+reports from users are the main drive behind improvements to
+CodeMirror. But first, please read over these points:
+
+
+
CodeMirror is maintained by volunteers. They don't owe you
+ anything, so be polite. Reports with an indignant or belligerent
+ tone tend to be moved to the bottom of the pile.
+
+
Include information about the browser in which the
+ problem occurred. Even if you tested several browsers, and
+ the problem occurred in all of them, mention this fact in the bug
+ report. Also include browser version numbers and the operating
+ system that you're on.
+
+
Mention which release of CodeMirror you're using. Preferably,
+ try also with the current development snapshot, to ensure the
+ problem has not already been fixed.
+
+
Mention very precisely what went wrong. "X is broken" is not a
+ good bug report. What did you expect to happen? What happened
+ instead? Describe the exact steps a maintainer has to take to make
+ the problem occur. We can not fix something that we can not
+ observe.
+
+
If the problem can not be reproduced in any of the demos
+ included in the CodeMirror distribution, please provide an HTML
+ document that demonstrates the problem. The best way to do this is
+ to go to jsbin.com, enter
+ it there, press save, and include the resulting link in your bug
+ report.
There are a few things in the 2.2 release that require some care
+when upgrading.
+
+
No more default.css
+
+
The default theme is now included
+in codemirror.css, so
+you do not have to included it separately anymore. (It was tiny, so
+even if you're not using it, the extra data overhead is negligible.)
+
+
Different key customization
+
+
CodeMirror has moved to a system
+where keymaps are used to
+bind behavior to keys. This means custom
+bindings are now possible.
+
+
Three options that influenced key
+behavior, tabMode, enterMode,
+and smartHome, are no longer supported. Instead, you can
+provide custom bindings to influence the way these keys act. This is
+done through the
+new extraKeys
+option, which can hold an object mapping key names to functionality. A
+simple example would be:
Keys can be mapped either to functions, which will be given the
+editor instance as argument, or to strings, which are mapped through
+functions through the CodeMirror.commands table, which
+contains all the built-in editing commands, and can be inspected and
+extended by external code.
+
+
By default, the Home key is bound to
+the "goLineStartSmart" command, which moves the cursor to
+the first non-whitespace character on the line. You can set do this to
+make it always go to the very start instead:
+
+
extraKeys: {"Home": "goLineStart"}
+
+
Similarly, Enter is bound
+to "newlineAndIndent" by default. You can bind it to
+something else to get different behavior. To disable special handling
+completely and only get a newline character inserted, you can bind it
+to false:
+
+
extraKeys: {"Enter": false}
+
+
The same works for Tab. If you don't want CodeMirror
+to handle it, bind it to false. The default behaviour is
+to indent the current line more ("indentMore" command),
+and indent it less when shift is held ("indentLess").
+There are also "indentAuto" (smart indent)
+and "insertTab" commands provided for alternate
+behaviors. Or you can write your own handler function to do something
+different altogether.
+
+
Tabs
+
+
Handling of tabs changed completely. The display width of tabs can
+now be set with the tabSize option, and tabs can
+be styled by setting CSS rules
+for the cm-tab class.
+
+
The default width for tabs is now 4, as opposed to the 8 that is
+hard-wired into browsers. If you are relying on 8-space tabs, make
+sure you explicitly set tabSize: 8 in your options.
CodeMirror is a JavaScript library that can
+ be used to create a relatively pleasant editor interface for
+ code-like content ― computer programs, HTML markup, and
+ similar. If a mode has been written for the language you are
+ editing, the code will be coloured, and the editor will optionally
+ help you with indentation.
+
+
This is the project page for CodeMirror 2, the currently more
+ actively developed, and recommended
+ version. CodeMirror 1 is still available
+ from here.
CodeMirror can also be found on GitHub at marijnh/CodeMirror2.
+ If you plan to hack on the code and contribute patches, the best way
+ to do it is to create a GitHub fork, and send pull requests.
+
+
Documentation
+
+
The manual is your first stop for
+ learning how to use this library. It starts with a quick explanation
+ of how to use the editor, and then describes the API in detail.
+
+
For those who want to learn more about the code, there is
+ an overview of the internals available.
+ The source code
+ itself is, for the most part, also well commented.
The following browsers are able to run CodeMirror:
+
+
+
Firefox 2 or higher
+
Chrome, any version
+
Safari 3 or higher
+
Internet Explorer 6 or higher
+
Opera 9 or higher (with some key-handling problems on OS X)
+
+
+
I am not actively testing against every new browser release, and
+ vendors have a habit of introducing bugs all the time, so I am
+ relying on the community to tell me when something breaks.
+ See here for information on how to contact
+ me.
+
+
Commercial support
+
+
CodeMirror is developed and maintained by me, Marijn Haverbeke,
+ in my own time. If your company is getting value out of CodeMirror,
+ please consider purchasing a support contract.
+
+
+
You'll be funding further work on CodeMirror.
+
You ensure that you get a quick response when you have a
+ problem, even when I am otherwise busy.

CodeMirror: C-like mode
+
+
+
+
+
+
Simple mode that tries to handle C-like languages as well as it
+ can. Takes two configuration parameters: keywords, an
+ object whose property names are the keywords in the language,
+ and useCPP, which determines whether C preprocessor
+ directives are recognized.
Mode for html embedded scripts like JSP and ASP.NET. Depends on HtmlMixed which in turn depends on
+ JavaScript, CSS and XML. Other dependancies include those of the scriping language chosen.
Loosely based on Franciszek
+ Wawrzak's CodeMirror
+ 1 mode. One configuration parameter is
+ supported, specials, to which you can provide an
+ array of strings to have those identifiers highlighted with
+ the lua-special style.
+ Simple mode that handles Oracle PL/SQL language (and Oracle SQL, of course).

CodeMirror: reStructuredText mode
+
+
+
+
+
The reStructuredText mode supports one configuration parameter:
+
+
verbatim (string)
+
A name or MIME type of a mode that will be used for highlighting
+ verbatim blocks. By default, reStructuredText mode uses uniform color
+ for whole block of verbatim text if no mode is given.
+
+
If python mode is available,
+ it will be used for highlighting blocks containing Python/IPython terminal
+ sessions (blocks starting with >>> (for Python) or
+ In [num]: (for IPython).
+
+
MIME types defined:text/x-rst.

CodeMirror: Verilog mode
+
+
+
+
+
+
Simple mode that tries to handle Verilog-like languages as well as it
+ can. Takes one configuration parameters: keywords, an
+ object whose property names are the keywords in the language.
The XML mode supports two configuration parameters:
+
+
htmlMode (boolean)
+
This switches the mode to parse HTML instead of XML. This
+ means attributes do not have to be quoted, and some elements
+ (such as br) do not require a closing tag.
+
alignCDATA (boolean)
+
Setting this to true will force the opening tag of CDATA
+ blocks to not be indented.
/* Script compression
+ helper */
+
/* In-browser code editing
+ made bearable */
