+/**
+ * Tag-closer extension for CodeMirror.
+ *
+ * This extension adds an "autoCloseTags" option that can be set to
+ * either true to get the default behavior, or an object to further
+ * configure its behavior.
+ *
+ * These are supported options:
+ *
+ * `whenClosing` (default true)
+ *   Whether to autoclose when the '/' of a closing tag is typed.
+ * `whenOpening` (default true)
+ *   Whether to autoclose the tag when the final '>' of an opening
+ *   tag is typed.
+ * `dontCloseTags` (default is empty tags for HTML, none for XML)
+ *   An array of tag names that should not be autoclosed.
+ * `indentTags` (default is block tags for HTML, none for XML)
+ *   An array of tag names that should, when opened, cause a
+ *   blank line to be added inside the tag, and the blank line and
+ *   closing line to be indented.
+ *
+ * See demos/closetag.html for a usage example.

+// Highlighting text that matches the selection

+// Defines an option highlightSelectionMatches, which, when enabled,

+// document.
+//
+// The option can be set to true to simply enable it, or to a
+// {minChars, style, wordsOnly, showToken, delay} object to explicitly
+// configure it. minChars is the minimum amount of characters that should be
+// selected for the behavior to occur, and style is the token style to
+// apply to the matches. This will be prefixed by "cm-" to create an
+// actual CSS class name. If wordsOnly is enabled, the matches will be
+// highlighted only if the selected text is a word. showToken, when enabled,
+// will cause the current token to be highlighted when nothing is selected.
+// delay is used to specify how much time to wait, in milliseconds, before
+// highlighting the matches. If annotateScrollbar is enabled, the occurences
+// will be highlighted on the scrollbar via the matchesonscrollbar addon.

+// CodeMirror, copyright (c) by Marijn Haverbeke and others

+
+// Glue code between CodeMirror and Tern.
+//
+// Create a CodeMirror.TernServer to wrap an actual Tern server,
+// register open documents (CodeMirror.Doc instances) with it, and
+// call its methods to activate the assisting functions that Tern
+// provides.
+//
+// Options supported (all optional):
+// * defs: An array of JSON definition data structures.
+// * plugins: An object mapping plugin names to configuration
+//   options.
+// * getFile: A function(name, c) that can be used to access files in
+//   the project that haven't been loaded yet. Simply do c(null) to
+//   indicate that a file is not available.
+// * fileFilter: A function(value, docName, doc) that will be applied
+//   to documents before passing them on to Tern.
+// * switchToDoc: A function(name, doc) that should, when providing a
+//   multi-file view, switch the view or focus to the named file.
+// * showError: A function(editor, message) that can be used to
+//   override the way errors are displayed.
+// * completionTip: Customize the content in tooltips for completions.
+//   Is passed a single argument—the completion's data as returned by
+//   Tern—and may return a string, DOM node, or null to indicate that
+//   no tip should be shown. By default the docstring is shown.
+// * typeTip: Like completionTip, but for the tooltips shown for type
+//   queries.
+// * responseFilter: A function(doc, query, request, error, data) that
+//   will be applied to the Tern responses before treating them
+//
+//
+// It is possible to run the Tern server in a web worker by specifying
+// these additional options:
+// * useWorker: Set to true to enable web worker mode. You'll probably
+//   want to feature detect the actual value you use here, for example
+//   !!window.Worker.
+// * workerScript: The main script of the worker. Point this to
+//   wherever you are hosting worker.js from this directory.
+// * workerDeps: An array of paths pointing (relative to workerScript)
+//   to the Acorn and Tern libraries and any Tern plugins you want to
+//   load. Or, if you minified those into a single script and included
+//   them in the workerScript, simply leave this undefined.
