- * A note on `__proto__`:
- *
- * This file uses ordinary objects to track identifiers that are observed in
- * the input source code. It creates these objects using `Object.create` so
- * that the tracking objects have no prototype, allowing the `__proto__`
- * property to be used to store a value *without* triggering the invocation of
- * the built-in `Object.prototype.__proto__` accessor method. Some environments
- * (e.g. PhantomJS) do not implement the correct semantics for property
- * enumeration. In those environments, methods like `Object.keys` and Lodash's
- * `values` do not include the property name. This file includes a number of
- * branches which ensure that JSHint behaves consistently in those
- * environments. The branches must be ignored by the test coverage verification
- * system because the workaround is not necessary in the environment where
- * coverage is verified (i.e. Node.js).

-    This file creates a json_parse function.
-
-        json_parse(text, reviver)
-            This method parses a JSON text to produce an object or array.
-            It can throw a SyntaxError exception.
-
-            The optional reviver parameter is a function that can filter and
-            transform the results. It receives each of the keys and values,
-            and its return value is used instead of the original value.
-            If it returns what it received, then the structure is not modified.
-            If it returns undefined then the member is deleted.
-
-            Example:
-
-            // Parse the text. Values that look like ISO date strings will
-            // be converted to Date objects.
-
-            myData = json_parse(text, function (key, value) {
-                var a;

-                    a =
-/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
-                    if (a) {
-                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],

-  // character codes instead of characters as string comparisons was the
-  // biggest bottleneck of the parser.
-  //
-  // If `options.comments` is enabled, all comments encountered will be stored
-  // in an array which later will be appended to the chunk object. If disabled,
-  // they will simply be disregarded.
-  //
-  // When the lexer has derived a valid token, it will be returned as an object
-  // containing its value and as well as its position in the input string (this
-  // is always enabled to provide proper debug messages).

-  // Parser
-  // ------
-
-  // Export the main parser.
-  //
-  //   - `wait` Hold parsing until end() is called. Defaults to false
-  //   - `comments` Store comments. Defaults to true.
-  //   - `scope` Track identifier scope. Defaults to false.
-  //   - `locations` Store location information. Defaults to false.
-  //   - `ranges` Store the start and end character locations. Defaults to
-  //     false.
-  //   - `onCreateNode` Callback which will be invoked when a syntax node is
-  //     created.
-  //   - `onCreateScope` Callback which will be invoked when a new scope is
-  //     created.
-  //   - `onDestroyScope` Callback which will be invoked when the current scope
-  //     is destroyed.
-  //
-  // Example:
-  //
-  //     var parser = require('luaparser');
-  //     parser.parse('i = 0');
