Running a CodeMirror mode outside of the editor.
+    The CodeMirror.runMode function, defined

+
+    

+      
text (string)

+      
The document to run through the highlighter.

mode (mode spec)

+      
The mode to use (must be loaded as normal).

+      
output (function or DOM node)

+      
If this is a function, it will be called for each token with
+      two arguments, the token's text and the token's style class (may
+      be null for unstyled tokens). If it is a DOM node,
+      the tokens will be converted to span elements as in

+      (through innerHTML).

To optimize loading CodeMirror, especially when including a
+    bunch of different modes, it is recommended that you combine and
+    minify (and preferably also gzip) the scripts. This page makes
+    those first two steps very easy. Simply select the version and
+    scripts you need in the form below, and
+    click Compress to download the minified script
+    file.

Caution: this text was written briefly after

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.

+
+    
Overview

+
+    
CodeMirror is a code-editor component that can be embedded in
+    Web pages. The core 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 addons included in the distribution,
+    and the list
+    of externally hosted addons, 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 number
+    of 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.
+    (See the compression helper for an
+    easy way to combine scripts.) For example:

+
+    
<script src="lib/codemirror.js"></script>
+<link rel="stylesheet" href="../lib/codemirror.css">
+<script src="mode/javascript/javascript.js"></script>

+
+    
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:

+
+    
var myCodeMirror = CodeMirror(document.body, {
+  value: "function myScript(){return 100;}\n",
+  mode:  "javascript"
+});

+
+    
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:

+
+    
var myCodeMirror = CodeMirror(function(elt) {
+  myTextArea.parentNode.replaceChild(elt, myTextArea);
+}, {value: myTextArea.value});

+
+    
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 with the editor's contents 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|CodeMirror.Doc

+      
The starting value of the editor. Can be a string, or
+      a document object.

+
+      
mode: string|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 have been defined by inspecting
+      the CodeMirror.modes
+      and CodeMirror.mimeModes objects. The first maps
+      mode names to their constructors, and the second maps MIME types
+      to mode specs.

+
+      
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.

+
+      
rtlMoveVisually: boolean

+      
Determines whether horizontal cursor movement through
+      right-to-left (Arabic, Hebrew) text is visual (pressing the left
+      arrow moves the cursor left) or logical (pressing the left arrow
+      moves to the next lower index in the string, which is visually
+      right in right-to-left text). The default is false
+      on Windows, and true on other platforms.

+
+      
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. See
+      the section on keymaps for more
+      information.

+
+      
extraKeys: object

+      
Can be used to specify extra keybindings for the editor,
+      alongside the ones defined
+      by keyMap. Should be
+      either null, or a valid keymap value.

+
+      
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.

+
+      
lineNumberFormatter: function(line: integer) → string

+      
A function used to format line numbers. The function is
+      passed the line number, and should return a string that will be
+      shown in the gutter.

+
+      
gutters: array<string>

+      
Can be used to add extra gutters (beyond or instead of the
+      line number gutter). Should be an array of CSS class names, each
+      of which defines a width (and optionally a
+      background), and which will be used to draw the background of
+      the gutters. May include
+      the CodeMirror-linenumbers class, in order to
+      explicitly set the position of the line number gutter (it will
+      default to be to the right of all other gutters). These class
+      names are the keys passed
+      to setGutterMarker.

+
+      
fixedGutter: boolean

+      
Determines whether the gutter scrolls along with the content
+      horizontally (false) or whether it stays fixed during horizontal
+      scrolling (true, the default).

+
+      
coverGutterNextToScrollbar: boolean

+      
When fixedGutter
+      is on, and there is a horizontal scrollbar, by default the
+      gutter will be visible to the left of this scrollbar. If this
+      option is set to true, it will be covered by an element with
+      class CodeMirror-gutter-filler.

+
+      
readOnly: boolean|string

+      
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.

+
+      
showCursorWhenSelecting: boolean

+      
Whether the cursor should be drawn when a selection is
+      active. Defaults to false.

+
+      
undoDepth: integer

+      
The maximum number of undo levels that the editor stores.
+      Defaults to 40.

+
+      
historyEventDelay: integer

+      
The period of inactivity (in milliseconds) that will cause a
+      new history event to be started when typing or deleting.
+      Defaults to 500.

+
+      
tabindex: integer

+      
The tab
+      index to assign to the editor. If not given, no tab index
+      will be assigned.

+
+      
autofocus: boolean

+      
Can be used to make CodeMirror focus itself on
+      initialization. Defaults to off.
+      When fromTextArea is
+      used, and no explicit value is given for this option, it will be
+      set to true when either the source textarea is focused, or it
+      has an autofocus attribute and no other element is
+      focused.

+    

+
+    
Below this a few more specialized, low-level options are
+    listed. These are only useful in very specific situations, you
+    might want to skip them the first time you read this manual.

+
+    

+      
dragDrop: boolean

+      
Controls whether drag-and-drop is enabled. On by default.

+
+      
onDragEvent: function(instance: CodeMirror, event: Event) → boolean

+      
Deprecated! See these event
+      handlers for the current recommended approach.
When given,
+      this will be called when the editor is handling
+      a dragenter, dragover,
+      or drop event. It will be passed the editor
+      instance and the event object as arguments. The callback can
+      choose to handle the event itself, in which case it should
+      return true to indicate that CodeMirror should not
+      do anything further.

+
+      
onKeyEvent: function(instance: CodeMirror, event: Event) → boolean

+      
Deprecated! See these event
+      handlers for the current recommended approach.
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).

+
+      
cursorBlinkRate: number

+      
Half-period in milliseconds used for cursor blinking. The default blink
+      rate is 530ms.

+
+      
cursorScrollMargin: number

+      
How much extra space to always keep above and below the
+      cursor when approaching the top or bottom of the visible view in
+      a scrollable document. Default is 0.

+
+      
cursorHeight: number

+      
Determines the height of the cursor. Default is 1, meaning
+      it spans the whole height of the line. For some fonts (and by
+      some tastes) a smaller height (for example 0.85),
+      which causes the cursor to not reach all the way to the bottom
+      of the line, looks better

+
+      
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.

+
+      
workDelay: number

+      
See workTime.

+
+      
pollInterval: number

+      
Indicates how quickly CodeMirror should poll its input
+      textarea for changes (when focused). Most input is captured by
+      events, but some things, like IME input on some browsers, don't
+      generate events that allow CodeMirror to properly detect it.
+      Thus, it polls. Default is 100 milliseconds.

+
+      
flattenSpans: boolean

+      
By default, CodeMirror will combine adjacent tokens into a
+      single span if they have the same class. This will result in a
+      simpler DOM tree, and thus perform better. With some kinds of
+      styling (such as rounded corners), this will change the way the
+      document looks. You can set this option to false to disable this
+      behavior.

+
+      
maxHighlightLength: number

+      
When highlighting long lines, in order to stay responsive,
+      the editor will give up and simply style the rest of the line as
+      plain text when it reaches a certain position. The default is
+      10000. You can set this to Infinity to turn off
+      this behavior.

+
+      
viewportMargin: integer

+      
Specifies the amount of lines that are rendered above and
+      below the part of the document that's currently scrolled into
+      view. This affects the amount of updates needed when scrolling,
+      and the amount of work that such an update does. You should
+      usually leave it at its default, 10. Can be set
+      to Infinity to make sure the whole document is
+      always rendered, and thus the browser's text search works on it.
+      This will have bad effects on performance of big
+      documents.

+    

+
+    
Events

+
+    
Various CodeMirror-related objects emit events, which allow
+    client code to react to various situations. Handlers for such
+    events can be registed with the on
+    and off methods on the objects
+    that the event fires on. To fire your own events,
+    use CodeMirror.signal(target, name, args...),
+    where target is a non-DOM-node object.

+
+    
An editor instance fires the following events.
+    The instance argument always refers to the editor
+    itself.

+
+    

+      
"change" (instance: CodeMirror, changeObj: object)

+      
Fires every time the content of the editor is changed.
+      The changeObj is a {from, to, text, removed,
+      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 the beginning of line #19). text is
+      an array of strings representing the text that replaced the
+      changed range (split by line). removed is the text
+      that used to be between from and to,
+      which is overwritten by this change. 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).

+
+      
"beforeChange" (instance: CodeMirror, changeObj: object)

+      
This event is fired before a change is applied, and its
+      handler may choose to modify or cancel the change.
+      The changeObj object
+      has from, to, and text
+      properties, as with
+      the "change" event, but
+      never a next property, since this is fired for each
+      individual change, and not batched per operation. It also has
+      a cancel() method, which can be called to cancel
+      the change, and, if the change isn't coming
+      from an undo or redo event, an update(from, to,
+      text) method, which may be used to modify the change.
+      Undo or redo changes can't be modified, because they hold some
+      metainformation for restoring old marked ranges that is only
+      valid for that specific change. All three arguments
+      to update are optional, and can be left off to
+      leave the existing value for that field
+      intact. Note: you may not do anything from
+      a "beforeChange" handler that would cause changes
+      to the document or its visualization. Doing so will, since this
+      handler is called directly from the bowels of the CodeMirror
+      implementation, probably cause the editor to become
+      corrupted.

+
+      
"cursorActivity" (instance: CodeMirror)

+      
Will be fired when the cursor or selection moves, or any
+      change is made to the editor content.

+
+      
"keyHandled" (instance: CodeMirror, name: string, event: Event)

+      
Fired after a key is handled through a
+      keymap. name is the name of the handled key (for
+      example "Ctrl-X" or "'q'"),
+      and event is the DOM keydown
+      or keypress event.

+
+      
"inputRead" (instance: CodeMirror, changeObj: object)

+      
Fired whenever new input is read from the hidden textarea
+      (typed or pasted by the user).

+
+      
"beforeSelectionChange" (instance: CodeMirror, selection: {head, anchor})

+      
This event is fired before the selection is moved. Its
+      handler may modify the resulting selection head and anchor.
+      The selection parameter is an object
+      with head and anchor properties
+      holding {line, ch} objects, which the handler can
+      read and update. Handlers for this event have the same
+      restriction
+      as "beforeChange"
+      handlers — they should not do anything to directly update the
+      state of the editor.

+
+      
"viewportChange" (instance: CodeMirror, from: number, to: number)

+      
Fires whenever the view port of
+      the editor changes (due to scrolling, editing, or any other
+      factor). The from and to arguments
+      give the new start and end of the viewport.

+
+      
"gutterClick" (instance: CodeMirror, line: integer, gutter: string, clickEvent: Event)

+      
Fires when the editor gutter (the line-number area) is
+      clicked. Will pass the editor instance as first argument, the
+      (zero-based) number of the line that was clicked as second
+      argument, the CSS class of the gutter that was clicked as third
+      argument, and the raw mousedown event object as
+      fourth argument.

+
+      
"focus" (instance: CodeMirror)

+      
Fires whenever the editor is focused.

+
+      
"blur" (instance: CodeMirror)

+      
Fires whenever the editor is unfocused.

+
+      
"scroll" (instance: CodeMirror)

+      
Fires when the editor is scrolled.

+
+      
"update" (instance: CodeMirror)

+      
Will be fired whenever CodeMirror updates its DOM display.

+
+      
"renderLine" (instance: CodeMirror, line: LineHandle, element: Element)

+      
Fired whenever a line is (re-)rendered to the DOM. Fired
+      right after the DOM element is built, before it is
+      added to the document. The handler may mess with the style of
+      the resulting element, or add event handlers, but
+      should not try to change the state of the editor.

+
+      
"mousedown",
+      "dblclick", "contextmenu", "keydown", "keypress",
+      "keyup", "dragstart", "dragenter",
+      "dragover", "drop"
+      (instance: CodeMirror, event: Event)

+      
Fired when CodeMirror is handling a DOM event of this type.
+      You can preventDefault the event, or give it a
+      truthy codemirrorIgnore property, to signal that
+      CodeMirror should do no further handling.

+    

+
+    
Document objects (instances
+    of CodeMirror.Doc) emit the
+    following events:

+
+    

+      
"change" (doc: CodeMirror.Doc, changeObj: object)

+      
Fired whenever a change occurs to the
+      document. changeObj has a similar type as the
+      object passed to the
+      editor's "change"
+      event, but it never has a next property, because
+      document change events are not batched (whereas editor change
+      events are).

+
+      
"beforeChange" (doc: CodeMirror.Doc, change: object)

+      
See the description of the
+      same event on editor instances.

+
+      
"cursorActivity" (doc: CodeMirror.Doc)

+      
Fired whenever the cursor or selection in this document
+      changes.

+
+      
"beforeSelectionChange" (doc: CodeMirror.Doc, selection: {head, anchor})

+      
Equivalent to
+      the event by the same
+      name as fired on editor instances.

+    

+
+    
Line handles (as returned by, for
+    example, getLineHandle)
+    support these events:

+
+    

+      
"delete" ()

+      
Will be fired when the line object is deleted. A line object
+      is associated with the start of the line. Mostly useful
+      when you need to find out when your gutter
+      markers on a given line are removed.

+      
"change" (line: LineHandle, changeObj: object)

+      
Fires when the line's text content is changed in any way
+      (but the line is not deleted outright). The change
+      object is similar to the one passed
+      to change event on the editor
+      object.

+    

+
+    
Marked range handles (CodeMirror.TextMarker), as returned
+    by markText
+    and setBookmark, emit the
+    following events:

+
+    

+      
"beforeCursorEnter" ()

+      
Fired when the cursor enters the marked range. From this
+      event handler, the editor state may be inspected
+      but not modified, with the exception that the range on
+      which the event fires may be cleared.

+      
"clear" (from: {line, ch}, to: {line, ch})

+      
Fired when the range is cleared, either through cursor
+      movement in combination
+      with clearOnEnter
+      or through a call to its clear() method. Will only
+      be fired once per handle. Note that deleting the range through
+      text editing does not fire this event, because an undo action
+      might bring the range back into existence. from
+      and to give the part of the document that the range
+      spanned when it was cleared.

+      
"hide" ()

+      
Fired when the last part of the marker is removed from the
+      document by editing operations.

+      
"unhide" ()

+      
Fired when, after the marker was removed by editing, a undo
+      operation brought the marker back.

+    

+
+    
Line widgets (CodeMirror.LineWidget), returned
+    by addLineWidget, fire
+    these events:

+
+    

+      
"redraw" ()

+      
Fired whenever the editor re-adds the widget to the DOM.
+      This will happen once right after the widget is added (if it is
+      scrolled into view), and then again whenever it is scrolled out
+      of view and back in again, or when changes to the editor options
+      or the line the widget is on require the widget to be
+      redrawn.

+    

+
+    
Keymaps

+
+    
Keymaps are ways to associate keys with functionality. A keymap
+    is an object mapping strings that identify the keys to functions
+    that implement their functionality.

+
+    
Keys are identified either by name or by character.
+    The CodeMirror.keyNames object defines names for
+    common keys and associates them with their key codes. Examples of
+    names defined here are Enter, F5,
+    and Q. These can be prefixed
+    with Shift-, Cmd-, Ctrl-,
+    and Alt- (in that order!) to specify a modifier. So
+    for example, Shift-Ctrl-Space would be a valid key
+    identifier.

+
+    
Common example: map the Tab key to insert spaces instead of a tab
+    character.

+
+    
+{
+  Tab: function(cm) {
+    var spaces = Array(cm.getOption("indentUnit") + 1).join(" ");
+    cm.replaceSelection(spaces, "end", "+input");
+  }
+}

+
+    
Alternatively, a character can be specified directly by
+    surrounding it in single quotes, for example '$'
+    or 'q'. Due to limitations in the way browsers fire
+    key events, these may not be prefixed with modifiers.

+
+    
The CodeMirror.keyMap object associates keymaps
+    with names. User code and keymap definitions can assign extra
+    properties to this object. Anywhere where a keymap is expected, a
+    string can be given, which will be looked up in this object. It
+    also contains the "default" keymap holding the
+    default bindings.

+
+    
The values of properties in keymaps can be either functions of
+    a single argument (the CodeMirror instance), strings, or
+    false. Such strings refer to properties of the
+    CodeMirror.commands object, which defines a number of
+    common commands that are used by the default keybindings, and maps
+    them to functions. If the property is set to false,
+    CodeMirror leaves handling of the key up to the browser. A key
+    handler function may return CodeMirror.Pass to indicate
+    that it has decided not to handle the key, and other handlers (or
+    the default behavior) should be given a turn.

+
+    
Keys mapped to command names that start with the
+    characters "go" (which should be used for
+    cursor-movement actions) will be fired even when an
+    extra Shift modifier is present (i.e. "Up":
+    "goLineUp" matches both up and shift-up). This is used to
+    easily implement shift-selection.

+
+    
Keymaps can defer to each other by defining
+    a fallthrough property. This indicates that when a
+    key is not found in the map itself, one or more other maps should
+    be searched. It can hold either a single keymap or an array of
+    keymaps.

+
+    
When a keymap contains a nofallthrough property
+    set to true, keys matched against that map will be
+    ignored if they don't match any of the bindings in the map (no
+    further child maps will be tried). When
+    the disableInput property is set
+    to true, the default effect of inserting a character
+    will be suppressed when the keymap is active as the top-level
+    map.

+
+    
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 the
+      editor width, height, 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

+      
Whether the editor scrolls (overflow: auto +
+      fixed height). By default, it does. Setting
+      the CodeMirror class to have height:
+      auto and giving this class overflow-x: auto;
+      overflow-y: hidden; 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-gutters

+      
This is the backdrop for all gutters. Use it to set the
+      default gutter background color, and optionally add a border on
+      the right of the gutters.

+
+      
CodeMirror-linenumbers

+      
Use this for giving a background or width to the line number
+      gutter.

+
+      
CodeMirror-linenumber

+      
Used to style the actual individual line numbers. These
+      won't be children of the CodeMirror-linenumbers
+      (plural) element, but rather will be absolutely positioned to
+      overlay it. Use this to set alignment and text properties for
+      the line numbers.

+
+      
CodeMirror-lines

+      
The visible lines. This is where you specify vertical
+      padding for the editor content.

+
+      
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.

+
+      
CodeMirror-matchingbracket,
+        CodeMirror-nonmatchingbracket

+      
These are used to style matched (or unmatched) brackets.

+    

+
+    
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. Thus, you need to write code (or
+    use addons) if you want to expose them to
+    your users.

+
+    
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.

+
+    
Methods prefixed with doc. can, unless otherwise
+    specified, be called both on CodeMirror (editor)
+    instances and CodeMirror.Doc instances. Methods
+    prefixed with cm. are only available
+    on CodeMirror instances.

+
+    
Constructor

+
+    
Constructing an editor instance is done with
+    the CodeMirror(place: Element|fn(Element),
+    ?option: object) constructor. If the place
+    argument is a DOM element, the editor will be appended to it. If
+    it is a function, it will be called, and is expected to place the
+    editor into the document. options may be an element
+    mapping option names to values. The options
+    that it doesn't explicitly specify (or all options, if it is not
+    passed) will be taken
+    from CodeMirror.defaults.

+
+    
Note that the options object passed to the constructor will be
+    mutated when the instance's options
+    are changed, so you shouldn't share such
+    objects between instances.

+
+    
See CodeMirror.fromTextArea
+    for another way to construct an editor instance.

+
+    
Content manipulation methods

+
+    

+      
doc.getValue(?separator: string) → string

+      
Get the current editor content. You can pass it an optional
+      argument to specify the string to be used to separate lines
+      (defaults to "\n").

+      
doc.setValue(content: string)

+      
Set the editor content.

+
+      
doc.getRange(from: {line, ch}, to: {line, ch}, ?separator: string) → string

+      
Get the text between the given points in the editor, which
+      should be {line, ch} objects. An optional third
+      argument can be given to indicate the line separator string to
+      use (defaults to "\n").

+      
doc.replaceRange(replacement: string, from: {line, ch}, to: {line, ch})

+      
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.

+
+      
doc.getLine(n: integer) → string

+      
Get the content of line n.

+      
doc.setLine(n: integer, text: string)

+      
Set the content of line n.

+      
doc.removeLine(n: integer)

+      
Remove the given line from the document.

+
+      
doc.lineCount() → integer

+      
Get the number of lines in the editor.

+      
doc.firstLine() → integer

+      
Get the first line of the editor. This will
+      usually be zero but for linked sub-views,
+      or documents instantiated with a non-zero
+      first line, it might return other values.

+      
doc.lastLine() → integer

+      
Get the last line of the editor. This will
+      usually be doc.lineCount() - 1,
+      but for linked sub-views,
+      it might return other values.

+
+      
doc.getLineHandle(num: integer) → LineHandle

+      
Fetches the line handle for the given line number.

+      
doc.getLineNumber(handle: LineHandle) → integer

+      
Given a line handle, returns the current position of that
+      line (or null when it is no longer in the
+      document).

+      
doc.eachLine(f: (line: LineHandle))

+      
doc.eachLine(start: integer, end: integer, f: (line: LineHandle))

+      
Iterate over the whole document, or if start
+      and end line numbers are given, the range
+      from start up to (not including) end,
+      and call f for each line, passing the line handle.
+      This is a faster way to visit a range of line handlers than
+      calling getLineHandle
+      for each of them. Note that line handles have
+      a text property containing the line's content (as a
+      string).

+
+      
doc.markClean()

+      
Set the editor content as 'clean', a flag that it will
+      retain until it is edited, and which will be set again when such
+      an edit is undone again. Useful to track whether the content
+      needs to be saved. This function is deprecated in favor
+      of changeGeneration,
+      which allows multiple subsystems to track different notions of
+      cleanness without interfering.

+      
doc.changeGeneration() → integer

+      
Returns a number that can later be passed
+      to isClean to test whether
+      any edits were made (and not undone) in the meantime.

+      
doc.isClean(?generation: integer) → boolean

+      
Returns whether the document is currently clean — not
+      modified since initialization or the last call
+      to markClean if no
+      argument is passed, or since the matching call
+      to changeGeneration
+      if a generation value is given.

+    

+
+    
Cursor and selection methods

+
+    

+      
doc.getSelection() → string

+      
Get the currently selected code.

+      
doc.replaceSelection(replacement: string, ?collapse: string)

+      
Replace the selection with the given string. By default, the
+      new selection will span the inserted text. The
+      optional collapse argument can be used to change
+      this—passing "start" or "end" will
+      collapse the selection to the start or end of the inserted
+      text.

+
+      
doc.getCursor(?start: string) → {line, ch}

+      
start is a an optional string indicating which
+      end of the selection to return. It may
+      be "start", "end", "head"
+      (the side of the selection that moves when you press
+      shift+arrow), or "anchor" (the fixed side of the
+      selection). Omitting the argument is the same as
+      passing "head". A {line, ch} object
+      will be returned.

+      
doc.somethingSelected() → boolean

+      
Return true if any text is selected.

+      
doc.setCursor(pos: {line, ch})

+      
Set the cursor position. You can either pass a
+      single {line, ch} object, or the line and the
+      character as two separate parameters.

+      
doc.setSelection(anchor: {line, ch}, head: {line, ch})

+      
Set the selection range. anchor
+      and head should be {line, ch}
+      objects. head defaults to anchor when
+      not given.

+      
doc.extendSelection(from: {line, ch}, ?to: {line, ch})

+      
Similar
+      to setSelection, but
+      will, if shift is held or
+      the extending flag is set, move the
+      head of the selection while leaving the anchor at its current
+      place. pos2 is optional, and can be passed to
+      ensure a region (for example a word or paragraph) will end up
+      selected (in addition to whatever lies between that region and
+      the current anchor).

+      
doc.setExtending(value: boolean)

+      
Sets or clears the 'extending' flag, which acts similar to
+      the shift key, in that it will cause cursor movement and calls
+      to extendSelection
+      to leave the selection anchor in place.

+
+      
cm.hasFocus() → boolean

+      
Tells you whether the editor currently has focus.

+
+      
cm.findPosH(start: {line, ch}, amount: integer, unit: string, visually: boolean) → {line, ch, ?hitSide: boolean}

+      
Used to find the target position for horizontal cursor
+      motion. start is a {line, ch}
+      object, amount an integer (may be negative),
+      and unit one of the
+      string "char", "column",
+      or "word". Will return a position that is produced
+      by moving amount times the distance specified
+      by unit. When visually is true, motion
+      in right-to-left text will be visual rather than logical. When
+      the motion was clipped by hitting the end or start of the
+      document, the returned value will have a hitSide
+      property set to true.

+      
cm.findPosV(start: {line, ch}, amount: integer, unit: string) → {line, ch, ?hitSide: boolean}

+      
Similar to findPosH,
+      but used for vertical motion. unit may
+      be "line" or "page". The other
+      arguments and the returned value have the same interpretation as
+      they have in findPosH.

+    

+
+    
Configuration methods

+
+    

+      
cm.setOption(option: string, value: any)

+      
Change the configuration of the editor. option
+      should the name of an option,
+      and value should be a valid value for that
+      option.

+      
cm.getOption(option: string) → any

+      
Retrieves the current value of the given option for this
+      editor instance.

+
+      
cm.addKeyMap(map: object, bottom: boolean)

+      
Attach an additional keymap to the
+      editor. This is mostly useful for addons that need to register
+      some key handlers without trampling on
+      the extraKeys
+      option. Maps added in this way have a higher precedence than
+      the extraKeys
+      and keyMap options,
+      and between them, the maps added earlier have a lower precedence
+      than those added later, unless the bottom argument
+      was passed, in which case they end up below other keymaps added
+      with this method.

+      
cm.removeKeyMap(map: object)

+      
Disable a keymap added
+      with addKeyMap. Either
+      pass in the keymap object itself, or a string, which will be
+      compared against the name property of the active
+      keymaps.

+
+      
cm.addOverlay(mode: string|object, ?options: object)

+      
Enable a highlighting overlay. This is a stateless mini-mode
+      that can be used to add extra highlighting. For example,
+      the search addon uses it to
+      highlight the term that's currently being
+      searched. mode can be a mode
+      spec or a mode object (an object with
+      a token method).
+      The options parameter is optional. If given, it
+      should be an object. Currently, only the opaque
+      option is recognized. This defaults to off, but can be given to
+      allow the overlay styling, when not null, to
+      override the styling of the base mode entirely, instead of the
+      two being applied together.

+      
cm.removeOverlay(mode: string|object)

+      
Pass this the exact value passed for the mode
+      parameter to addOverlay,
+      or a string that corresponds to the name propery of
+      that value, to remove an overlay again.

+
+      
cm.on(type: string, func: (...args))

+      
Register an event handler for the given event type (a
+      string) on the editor instance. There is also
+      a CodeMirror.on(object, type, func) version
+      that allows registering of events on any object.

+      
cm.off(type: string, func: (...args))

+      
Remove an event handler on the editor instance. An
+      equivalent CodeMirror.off(object, type,
+      func) also exists.

+    

+
+    
Document management methods

+
+    
Each editor is associated with an instance
+    of CodeMirror.Doc, its document. A document
+    represents the editor content, plus a selection, an undo history,
+    and a mode. A document can only be
+    associated with a single editor at a time. You can create new
+    documents by calling the CodeMirror.Doc(text, mode,
+    firstLineNumber) constructor. The last two arguments are
+    optional and can be used to set a mode for the document and make
+    it start at a line number other than 0, respectively.

+
+    

+      
cm.getDoc() → Doc

+      
Retrieve the currently active document from an editor.

+      
doc.getEditor() → CodeMirror

+      
Retrieve the editor associated with a document. May
+      return null.

+
+      
cm.swapDoc(doc: CodeMirror.Doc) → Doc

+      
Attach a new document to the editor. Returns the old
+      document, which is now no longer associated with an editor.

+
+      
doc.copy(copyHistory: boolean) → Doc

+      
Create an identical copy of the given doc.
+      When copyHistory is true, the history will also be
+      copied. Can not be called directly on an editor.

+
+      
doc.linkedDoc(options: object) → Doc

+      
Create a new document that's linked to the target document.
+      Linked documents will stay in sync (changes to one are also
+      applied to the other) until unlinked.
+      These are the options that are supported:
+        

+          
sharedHist: boolean

+          
When turned on, the linked copy will share an undo
+          history with the original. Thus, something done in one of
+          the two can be undone in the other, and vice versa.

+          
from: integer

+          
to: integer

+          
Can be given to make the new document a subview of the
+          original. Subviews only show a given range of lines. Note
+          that line coordinates inside the subview will be consistent
+          with those of the parent, so that for example a subview
+          starting at line 10 will refer to its first line as line 10,
+          not 0.

+          
mode: string|object

+          
By default, the new document inherits the mode of the
+          parent. This option can be set to
+          a mode spec to give it a
+          different mode.

+        

+      
doc.unlinkDoc(doc: CodeMirror.Doc)

+      
Break the link between two documents. After calling this,
+      changes will no longer propagate between the documents, and, if
+      they had a shared history, the history will become
+      separate.

+      
doc.iterLinkedDocs(function: (doc: CodeMirror.Doc, sharedHist: boolean))

+      
Will call the given function for all documents linked to the
+      target document. It will be passed two arguments, the linked document
+      and a boolean indicating whether that document shares history
+      with the target.

+    

+
+    
History-related methods

+
+    

+      
doc.undo()

+      
Undo one edit (if any undo events are stored).

+      
doc.redo()

+      
Redo one undone edit.

+
+      
doc.historySize() → {undo: integer, redo: integer}

+      
Returns an object with {undo, redo} properties,
+      both of which hold integers, indicating the amount of stored
+      undo and redo operations.

+      
doc.clearHistory()

+      
Clears the editor's undo history.

+      
doc.getHistory() → object

+      
Get a (JSON-serializeable) representation of the undo history.

+      
doc.setHistory(history: object)

+      
Replace the editor's undo history with the one provided,
+      which must be a value as returned
+      by getHistory. Note that
+      this will have entirely undefined results if the editor content
+      isn't also the same as it was when getHistory was
+      called.

+    

+
+    
Text-marking methods

+
+    

+      
doc.markText(from: {line, ch}, to: {line, ch}, ?options: object) → TextMarker

+      
Can be used to mark a range of text with a specific CSS
+      class name. from and to should
+      be {line, ch} objects. The options
+      parameter is optional. When given, it should be an object that
+      may contain the following configuration options:
+      

+        
className: string

+        
Assigns a CSS class to the marked stretch of text.

+        
inclusiveLeft: boolean

+        
Determines whether
+        text inserted on the left of the marker will end up inside
+        or outside of it.

+        
inclusiveRight: boolean

+        
Like inclusiveLeft,
+        but for the right side.

+        
atomic: boolean

+        
Atomic ranges act as a single unit when cursor movement is
+        concerned—i.e. it is impossible to place the cursor inside of
+        them. In atomic ranges, inclusiveLeft
+        and inclusiveRight have a different meaning—they
+        will prevent the cursor from being placed respectively
+        directly before and directly after the range.

+        
collapsed: boolean

+        
Collapsed ranges do not show up in the display. Setting a
+        range to be collapsed will automatically make it atomic.

+        
clearOnEnter: boolean

+        
When enabled, will cause the mark to clear itself whenever
+        the cursor enters its range. This is mostly useful for
+        text-replacement widgets that need to 'snap open' when the
+        user tries to edit them. The
+        "clear" event
+        fired on the range handle can be used to be notified when this
+        happens.

+        
replacedWith: Element

+        
Use a given node to display this range. Implies both
+        collapsed and atomic. The given DOM node must be an
+        inline element (as opposed to a block element).

+        
handleMouseEvents: boolean

+        
When replacedWith is given, this determines
+        whether the editor will capture mouse and drag events
+        occurring in this widget. Default is false—the events will be
+        left alone for the default browser handler, or specific
+        handlers on the widget, to capture.

+        
readOnly: boolean

+        
A read-only span can, as long as it is not cleared, not be
+        modified except by
+        calling setValue to reset
+        the whole document. Note: adding a read-only span
+        currently clears the undo history of the editor, because
+        existing undo events being partially nullified by read-only
+        spans would corrupt the history (in the current
+        implementation).

+        
addToHistory: boolean

+        
When set to true (default is false), adding this marker
+        will create an event in the undo history that can be
+        individually undone (clearing the marker).

+        
startStyle: string
Can be used to specify
+        an extra CSS class to be applied to the leftmost span that
+        is part of the marker.

+        
endStyle: string
Equivalent
+        to startStyle, but for the rightmost span.

+        
title:
+        string
When given, will give the nodes created
+        for this span a HTML title attribute with the
+        given value.

+        
shared: boolean
When the
+        target document is linked to other
+        documents, you can set shared to true to make the
+        marker appear in all documents. By default, a marker appears
+        only in its target document.

+      

+      The method will return an object that represents the marker
+      (with constuctor CodeMirror.TextMarker), which
+      exposes three methods:
+      clear(), to remove the mark,
+      find(), which returns
+      a {from, to} object (both holding document
+      positions), indicating the current position of the marked range,
+      or undefined if the marker is no longer in the
+      document, and finally changed(),
+      which you can call if you've done something that might change
+      the size of the marker (for example changing the content of
+      a replacedWith
+      node), and want to cheaply update the display.

+
+      
doc.setBookmark(pos: {line, ch}, ?options: object) → TextMarker

+      
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.
+      The options argument is optional. If given, the following
+      properties are recognized:
+      

+        
widget: Element
Can be used to display a DOM
+        node at the current location of the bookmark (analogous to
+        the replacedWith
+        option to markText).

+        
insertLeft: boolean
By default, text typed
+        when the cursor is on top of the bookmark will end up to the
+        right of the bookmark. Set this option to true to make it go
+        to the left instead.

+      

+
+      
doc.findMarksAt(pos: {line, ch}) → array<TextMarker>

+      
Returns an array of all the bookmarks and marked ranges
+      present at the given position.

+      
doc.getAllMarks() → array<TextMarker>

+      
Returns an array containing all marked ranges in the document.

+    

+
+    
Widget, gutter, and decoration methods

+
+    

+      
cm.setGutterMarker(line: integer|LineHandle, gutterID: string, value: Element) → LineHandle

+      
Sets the gutter marker for the given gutter (identified by
+      its CSS class, see
+      the gutters option)
+      to the given value. Value can be either null, to
+      clear the marker, or a DOM element, to set it. The DOM element
+      will be shown in the specified gutter next to the specified
+      line.

+
+      
cm.clearGutter(gutterID: string)

+      
Remove all gutter markers in
+      the gutter with the given ID.

+
+      
cm.addLineClass(line: integer|LineHandle, where: string, class: string) → LineHandle

+      
Set a CSS class name for the given line. line
+      can be a number or a line handle. where determines
+      to which element this class should be applied, can can be one
+      of "text" (the text element, which lies in front of
+      the selection), "background" (a background element
+      that will be behind the selection), or "wrap" (the
+      wrapper node that wraps all of the line's elements, including
+      gutter elements). class should be the name of the
+      class to apply.

+
+      
cm.removeLineClass(line: integer|LineHandle, where: string, class: string) → LineHandle

+      
Remove a CSS class from a line. line can be a
+      line handle or number. where should be one
+      of "text", "background",
+      or "wrap"
+      (see addLineClass). class
+      can be left off to remove all classes for the specified node, or
+      be a string to remove only a specific class.

+
+      
cm.lineInfo(line: integer|LineHandle) → object

+      
Returns the line number, text content, and marker status of
+      the given line, which can be either a number or a line handle.
+      The returned object has the structure {line, handle, text,
+      gutterMarkers, textClass, bgClass, wrapClass, widgets},
+      where gutterMarkers is an object mapping gutter IDs
+      to marker elements, and widgets is an array
+      of line widgets attached to this
+      line, and the various class properties refer to classes added
+      with addLineClass.

+
+      
cm.addWidget(pos: {line, ch}, node: Element, scrollIntoView: boolean)

+      
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).

+
+      
cm.addLineWidget(line: integer|LineHandle, node: Element, ?options: object) → LineWidget

+      
Adds a line widget, an element shown below a line, spanning
+      the whole of the editor's width, and moving the lines below it
+      downwards. line should be either an integer or a
+      line handle, and node should be a DOM node, which
+      will be displayed below the given line. options,
+      when given, should be an object that configures the behavior of
+      the widget. The following options are supported (all default to
+      false):
+        

+          
coverGutter: boolean

+          
Whether the widget should cover the gutter.

+          
noHScroll: boolean

+          
Whether the widget should stay fixed in the face of
+          horizontal scrolling.

+          
above: boolean

+          
Causes the widget to be placed above instead of below
+          the text of the line.

+          
showIfHidden: boolean

+          
When true, will cause the widget to be rendered even if
+          the line it is associated with is hidden.

+          
handleMouseEvents: boolean

+          
Determines whether the editor will capture mouse and
+          drag events occurring in this widget. Default is false—the
+          events will be left alone for the default browser handler,
+          or specific handlers on the widget, to capture.

+          
insertAt: integer

+          
By default, the widget is added below other widgets for
+          the line. This option can be used to place it at a different
+          position (zero for the top, N to put it after the Nth other
+          widget). Note that this only has effect once, when the
+          widget is created.
+        

+      Note that the widget node will become a descendant of nodes with
+      CodeMirror-specific CSS classes, and those classes might in some
+      cases affect it. This method returns an object that represents
+      the widget placement. It'll have a line property
+      pointing at the line handle that it is associated with, and the following methods:
+        

+          
clear()
Removes the widget.

+          
changed()
Call
+          this if you made some change to the widget's DOM node that
+          might affect its height. It'll force CodeMirror to update
+          the height of the line that contains the widget.

+        

+      

+    

+
+    
Sizing, scrolling and positioning methods

+
+    

+      
cm.setSize(width: number|string, height: number|string)

+      
Programatically set the size of the editor (overriding the
+      applicable CSS
+      rules). width and height height
+      can be either numbers (interpreted as pixels) or CSS units
+      ("100%", for example). You can
+      pass null for either of them to indicate that that
+      dimension should not be changed.

+
+      
cm.scrollTo(x: number, y: number)

+      
Scroll the editor to a given (pixel) position. Both
+      arguments may be left as null
+      or undefined to have no effect.

+      
cm.getScrollInfo() → {left, top, width, height, clientWidth, clientHeight}

+      
Get an {left, top, width, height, clientWidth,
+      clientHeight} object that represents the current scroll
+      position, the size of the scrollable area, and the size of the
+      visible area (minus scrollbars).

+      
cm.scrollIntoView(pos: {line, ch}|{left, top, right, bottom}, ?margin: number)

+      
Scrolls the given element into view. pos may be
+      either a {line, ch} position, referring to a given
+      character, null, to refer to the cursor, or
+      a {left, top, right, bottom} object, in
+      editor-local coordinates. The margin parameter is
+      optional. When given, it indicates the amount of pixels around
+      the given area that should be made visible as well.

+
+      
cm.cursorCoords(where: boolean|{line, ch}, mode: string) → {left, top, bottom}

+      
Returns an {left, top, bottom} object
+      containing the coordinates of the cursor position.
+      If mode is "local", they will be
+      relative to the top-left corner of the editable document. If it
+      is "page" or not given, they are relative to the
+      top-left corner of the page. where can be a boolean
+      indicating whether you want the start (true) or the
+      end (false) of the selection, or, if a {line,
+      ch} object is given, it specifies the precise position at
+      which you want to measure.

+      
cm.charCoords(pos: {line, ch}, ?mode: string) → {left, right, top, bottom}

+      
Returns the position and dimensions of an arbitrary
+      character. pos should be a {line, ch}
+      object. This differs from cursorCoords in that
+      it'll give the size of the whole character, rather than just the
+      position that the cursor would have when it would sit at that
+      position.

+      
cm.coordsChar(object: {left, top}, ?mode: string) → {line, ch}

+      
Given an {left, top} object, returns
+      the {line, ch} position that corresponds to it. The
+      optional mode parameter determines relative to what
+      the coordinates are interpreted. It may
+      be "window", "page" (the default),
+      or "local".

+      
cm.lineAtHeight(height: number, ?mode: string) → number

+      
Computes the line at the given pixel
+      height. mode can be one of the same strings
+      that coordsChar
+      accepts.

+      
cm.heightAtLine(line: number, ?mode: string) → number

+      
Computes the height of the top of a line, in the coordinate
+      system specified by mode
+      (see coordsChar), which
+      defaults to "page". When a line below the bottom of
+      the document is specified, the returned value is the bottom of
+      the last line in the document.

+      
cm.defaultTextHeight() → number

+      
Returns the line height of the default font for the editor.

+      
cm.defaultCharWidth() → number

+      
Returns the pixel width of an 'x' in the default font for
+      the editor. (Note that for non-monospace fonts, this is mostly
+      useless, and even for monospace fonts, non-ascii characters
+      might have a different width).

+
+      
cm.getViewport() → {from: number, to: number}

+      
Returns a {from, to} object indicating the
+      start (inclusive) and end (exclusive) of the currently rendered
+      part of the document. In big documents, when most content is
+      scrolled out of view, CodeMirror will only render the visible
+      part, and a margin around it. See also
+      the viewportChange
+      event.

+
+      
cm.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.

+    

+
+    
Mode, state, and token-related methods

+
+    
When writing language-aware functionality, it can often be
+    useful to hook into the knowledge that the CodeMirror language
+    mode has. See the section on modes for a
+    more detailed description of how these work.

+
+    

+      
doc.getMode() → object

+      
Gets the (outer) mode object for the editor. Note that this
+      is distinct from getOption("mode"), which gives you
+      the mode specification, rather than the resolved, instantiated
+      mode object.

+
+      
doc.getModeAt(pos: {line, ch}) → object

+      
Gets the inner mode at a given position. This will return
+      the same as getMode for
+      simple modes, but will return an inner mode for nesting modes
+      (such as htmlmixed).

+
+      
cm.getTokenAt(pos: {line, ch}, ?precise: boolean) → object

+      
Retrieves information about the token the current mode found
+      before 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.

+        
type
The token type the mode assigned
+        to the token, such as "keyword"
+        or "comment" (may also be null).

+        
state
The mode's state at the end of this token.

+      

+      If precise is true, the token will be guaranteed to be accurate based on recent edits. If false or
+      not specified, the token will use cached state information, which will be faster but might not be accurate if
+      edits were recently made and highlighting has not yet completed.
+      

+
+      
cm.getTokenTypeAt(pos: {line, ch}) → string

+      
This is a (much) cheaper version
+      of getTokenAt useful for
+      when you just need the type of the token at a given position,
+      and no other information. Will return null for
+      unstyled tokens, and a string, potentially containing multiple
+      space-separated style names, otherwise.

+
+      
cm.getHelper(pos: {line, ch}, type: string) → helper

+      
Fetch appropriate helper for the given position. Helpers
+      provide a way to look up functionality appropriate for a mode.
+      The type argument provides the helper namespace
+      (see
+      also registerHelper),
+      in which the value will be looked up. The key that is used
+      depends on the mode active at the given
+      position. If the mode object contains a property with the same
+      name as the type argument, that is tried first.
+      Next, the mode's helperType, if any, is tried. And
+      finally, the mode's name.

+
+      
cm.getStateAfter(?line: integer, ?precise: boolean) → object

+      
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. precise is defined
+      as in getTokenAt().

+    

+
+    
Miscellaneous methods

+
+    

+      
cm.operation(func: () → any) → any

+      
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.

+
+      
cm.indentLine(line: integer, ?dir: string|integer)

+      
Adjust the indentation of the given line. The second
+      argument (which defaults to "smart") may be one of:
+        

+          
"prev"

+          
Base indentation on the indentation of the previous line.

+          
"smart"

+          
Use the mode's smart indentation if available, behave
+          like "prev" otherwise.

+          
"add"

+          
Increase the indentation of the line by
+          one indent unit.

+          
"subtract"

+          
Reduce the indentation of the line.

+          
<integer>

+          
Add (positive number) or reduce (negative number) the
+          indentation by the given amount of spaces.

+        

+
+      
cm.toggleOverwrite(?value: bool)

+      
Switches between overwrite and normal insert mode (when not
+      given an argument), or sets the overwrite mode to a specific
+      state (when given an argument).

+
+      
doc.posFromIndex(index: integer) → {line, ch}

+      
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.

+      
doc.indexFromPos(object: {line, ch}) → integer

+      
The reverse of posFromIndex.

+
+      
cm.focus()

+      
Give the editor focus.

+
+      
cm.getInputField() → TextAreaElement

+      
Returns the hidden textarea used to read input.

+      
cm.getWrapperElement() → Element

+      
Returns the DOM node that represents the editor, and
+      controls its size. Remove this from your tree to delete an
+      editor instance.

+      
cm.getScrollerElement() → Element

+      
Returns the DOM node that is responsible for the scrolling
+      of the editor.

+      
cm.getGutterElement() → Element

+      
Fetches the DOM node that contains the editor gutters.

+    

+
+    
Static properties

+    
The CodeMirror object itself provides
+    several useful properties.

+
+    

+      
CodeMirror.version: string

+      
It contains a string that indicates the version of the
+      library. This is a triple of
+      integers "major.minor.patch",
+      where patch is zero for releases, and something
+      else (usually one) for dev snapshots.

+
+      
CodeMirror.fromTextArea(textArea: TextAreaElement, ?config: object)

+      

+        The method provides another way to initialize an editor. It 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 three
+        additional methods:
+        

+          
cm.save()

+          
Copy the content of the editor into the textarea.

+
+          
cm.toTextArea()

+          
Remove the editor, and restore the original textarea (with
+          the editor's current content).

+
+          
cm.getTextArea() → TextAreaElement

+          
Returns the textarea that the instance was based on.

+        

+      

+
+      
CodeMirror.defaults: object

+      
An object containing default values for
+      all options. You can assign to its
+      properties to modify defaults (though this won't affect editors
+      that have already been created).

+
+      
CodeMirror.defineExtension(name: string, value: any)

+      
If you want to define extra methods in terms of the
+      CodeMirror API, it is possible to
+      use defineExtension. This will cause the given
+      value (usually a method) to be added to all CodeMirror instances
+      created from then on.

+
+      
CodeMirror.defineDocExtension(name: string, value: any)

+      
Like defineExtension,
+      but the method will be added to the interface
+      for Doc objects instead.

+
+      
CodeMirror.defineOption(name: string,
+      default: any, updateFunc: function)

+      
Similarly, defineOption can be used to define new options for
+      CodeMirror. The updateFunc will be called with the
+      editor instance and the new value when an editor is initialized,
+      and whenever the option is modified
+      through setOption.

+
+      
CodeMirror.defineInitHook(func: function)

+      
If your extention just needs to run some
+      code whenever a CodeMirror instance is initialized,
+      use CodeMirror.defineInitHook. Give it a function as
+      its only argument, and from then on, that function will be called
+      (with the instance as argument) whenever a new CodeMirror instance
+      is initialized.

+
+      
CodeMirror.registerHelper(type: string, name: string, value: helper)

+      
Registers a helper value with the given name in
+      the given namespace (type). This is used to define
+      functionality that may be looked up by mode. Will create (if it
+      doesn't already exist) a property on the CodeMirror
+      object for the given type, pointing to an object
+      that maps names to values. I.e. after
+      doing CodeMirror.registerHelper("hint", "foo",
+      myFoo), the value CodeMirror.hint.foo will
+      point to myFoo.

+
+      
CodeMirror.Pos(line: integer, ?ch: integer)

+      
A constructor for the {line, ch} objects that
+      are used to represent positions in editor documents.

+
+      
CodeMirror.changeEnd(change: object) → {line, ch}

+      
Utility function that computes an end position from a change
+      (an object with from, to,
+      and text properties, as passed to
+      various event handlers). The
+      returned position will be the end of the changed
+      range, after the change is applied.

+    

+
+    
Addons

+
+    
The addon directory in the distribution contains a
+    number of reusable components that implement extra editor
+    functionality. In brief, they are:

+
+    

+      
dialog/dialog.js

+      
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 addon/dialog/dialog.css.

+
+      
search/searchcursor.js

+      
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() → boolean

+          
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() → {line, ch}

+          
to() → {line, ch}

+          
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: string)

+          
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.

+
+      
edit/matchbrackets.js

+      
Defines an option matchBrackets which, when set
+      to true, causes matching brackets to be highlighted whenever the
+      cursor is next to them. It also adds a
+      method matchBrackets that forces this to happen
+      once, and a method findMatchingBracket that can be
+      used to run the bracket-finding algorithm that this uses
+      internally.

+
+      
edit/closebrackets.js

+      
Defines an option autoCloseBrackets that will
+      auto-close brackets and quotes when typed. By default, it'll
+      auto-close ()[]{}''"", but you can pass it a string
+      similar to that (containing pairs of matching characters), or an
+      object with pairs and
+      optionally explode properties to customize
+      it. explode should be a similar string that gives
+      the pairs of characters that, when enter is pressed between
+      them, should have the second character also moved to its own
+      line. Demo here.

+
+      
edit/matchtags.js

+      
Defines an option matchTags that, when enabled,
+      will cause the tags around the cursor to be highlighted (using
+      the CodeMirror-matchingbrackets class). Also
+      defines
+      a command toMatchingTag,
+      which you can bind a key to in order to jump to the tag mathing
+      the one under the cursor. Depends on
+      the addon/fold/xml-fold.js
+      addon. Demo here.

+
+      
edit/trailingspace.js

+      
Adds an option showTrailingSpace which, when
+      enabled, adds the CSS class cm-trailingspace to
+      stretches of whitespace at the end of lines.
+      The demo has a nice
+      squiggly underline style for this class.

+
+      
comment/comment.js

+      
Addon for commenting and uncommenting code. Adds three
+      methods to CodeMirror instances:
+      

+        
lineComment(from: {line, ch}, to: {line, ch}, ?options: object)

+        
Set the lines in the given range to be line comments. Will
+        fall back to blockComment when no line comment
+        style is defined for the mode.

+        
blockComment(from: {line, ch}, to: {line, ch}, ?options: object)

+        
Wrap the code in the given range in a block comment. Will
+        fall back to lineComment when no block comment
+        style is defined for the mode.

+        
uncomment(from: {line, ch}, to: {line, ch}, ?options: object) → boolean

+        
Try to uncomment the given range.
+          Returns true if a comment range was found and
+          removed, false otherwise.

+      

+      The options object accepted by these methods may
+      have the following properties:
+      

+        
blockCommentStart, blockCommentEnd, blockCommentLead, lineComment: string

+        
Override the comment string
+        properties of the mode with custom comment strings.

+        
padding: string

+        
A string that will be inserted after opening and before
+        closing comment markers. Defaults to a single space.

+        
commentBlankLines: boolean

+        
Whether, when adding line comments, to also comment lines
+        that contain only whitespace.

+        
indent: boolean

+        
When adding line comments and this is turned on, it will
+        align the comment block to the current indentation of the
+        first line of the block.

+        
fullLines: boolean

+        
When block commenting, this controls whether the whole
+        lines are indented, or only the precise range that is given.
+        Defaults to true.

+      

+      The addon also defines
+      a toggleComment command,
+      which will try to uncomment the current selection, and if that
+      fails, line-comments it.

+
+      
fold/foldcode.js

+      
Helps with code folding. Adds a foldCode method
+      to editor instances, which will try to do a code fold starting
+      at the given line, or unfold the fold that is already present.
+      The method takes as first argument the position that should be
+      folded (may be a line number or
+      a Pos), and as second optional
+      argument either a range-finder function, or an options object,
+      supporting the following properties:
+      

+        
rangeFinder: fn(CodeMirror, Pos)

+        
The function that is used to find foldable ranges. If this
+        is not directly passed, it will
+        call getHelper with
+        a "fold" type to find one that's appropriate for
+        the mode. There are files in
+        the addon/fold/
+        directory providing CodeMirror.fold.brace, which
+        finds blocks in brace languages (JavaScript, C, Java,
+        etc), CodeMirror.fold.indent, for languages where
+        indentation determines block structure (Python, Haskell),
+        and CodeMirror.fold.xml, for XML-style
+        languages.

+        
widget: string|Element

+        
The widget to show for folded ranges. Can be either a
+        string, in which case it'll become a span with
+        class CodeMirror-foldmarker, or a DOM node.

+        
scanUp: boolean

+        
When true (default is false), the addon will try to find
+        foldable ranges on the lines above the current one if there
+        isn't an eligible one on the given line.

+        
minFoldSize: integer

+        
The minimum amount of lines that a fold should span to be
+        accepted. Defaults to 0, which also allows single-line
+        folds.

+      

+      See the demo for an
+      example.

+
+      
fold/foldgutter.js

+      
Provides an option foldGutter, which can be
+      used to create a gutter with markers indicating the blocks that
+      can be folded. Create a gutter using
+      the gutters option,
+      giving it the class CodeMirror-foldgutter or
+      something else if you configure the addon to use a different
+      class, and this addon will show markers next to folded and
+      foldable blocks, and handle clicks in this gutter. The option
+      can be either set to true, or an object containing
+      the following optional option fields:
+      

+        
gutter: string

+        
The CSS class of the gutter. Defaults
+        to "CodeMirror-foldgutter". You will have to
+        style this yourself to give it a width (and possibly a
+        background).

+        
indicatorOpen: string | Element

+        
A CSS class or DOM element to be used as the marker for
+        open, foldable blocks. Defaults
+        to "CodeMirror-foldgutter-open".

+        
indicatorFolded: string | Element

+        
A CSS class or DOM element to be used as the marker for
+        folded blocks. Defaults to "CodeMirror-foldgutter-folded".

+        
rangeFinder: fn(CodeMirror, Pos)

+        
The range-finder function to use when determining whether
+        something can be folded. When not
+        given, getHelper will be
+        used to determine a default.

+      

+      Demo here.

+
+      
runmode/runmode.js

+      
Can be used to run a CodeMirror mode over text without
+      actually opening an editor instance.
+      See the demo for an example.
+      There are alternate versions of the file avaible for
+      running stand-alone
+      (without including all of CodeMirror) and
+      for running under
+      node.js.

+
+      
mode/overlay.js

+      
Mode combinator that can be used to extend a mode with an
+      'overlay' — a secondary mode is run over the stream, along with
+      the base mode, and can color specific pieces of text without
+      interfering with the base mode.
+      Defines CodeMirror.overlayMode, which is used to
+      create such a mode. See this
+      demo for a detailed example.

+
+      
mode/multiplex.js

+      
Mode combinator that can be used to easily 'multiplex'
+      between several modes.
+      Defines CodeMirror.multiplexingMode which, when
+      given as first argument a mode object, and as other arguments
+      any number of {open, close, mode [, delimStyle, innerStyle]}
+      objects, will return a mode object that starts parsing using the
+      mode passed as first argument, but will switch to another mode
+      as soon as it encounters a string that occurs in one of
+      the open fields of the passed objects. When in a
+      sub-mode, it will go back to the top mode again when
+      the close string is encountered.
+      Pass "\n" for open or close
+      if you want to switch on a blank line.
+      
  • When delimStyle is specified, it will be the token
+      style returned for the delimiter tokens.
    • 
+      
  • When innerStyle is specified, it will be the token
+      style added for each inner mode token.

+      The outer mode will not see the content between the delimiters.
+      See this demo for an
+      example.

+
+      
hint/show-hint.js

+      
Provides a framework for showing autocompletion hints.
+      Defines CodeMirror.showHint, which takes a
+      CodeMirror instance, a hinting function, and optionally an
+      options object, and pops up a widget that allows the user to
+      select a completion. Hinting functions are function that take an
+      editor instance and an optional options object, and return
+      a {list, from, to} object, where list
+      is an array of strings or objects (the completions),
+      and from and to give the start and end
+      of the token that is being completed as {line, ch}
+      objects. If no hinting function is given, the addon will try to
+      use getHelper with
+      the "hint" type to find one. When completions
+      aren't simple strings, they should be objects with the folowing
+      properties:
+      

+        
text: string

+        
The completion text. This is the only required
+        property.

+        
displayText: string

+        
The text that should be displayed in the menu.

+        
className: string

+        
A CSS class name to apply to the completion's line in the
+        menu.

+        
render: fn(Element, self, data)

+        
A method used to create the DOM structure for showing the
+        completion by appending it to its first argument.

+        
hint: fn(CodeMirror, self, data)

+        
A method used to actually apply the completion, instead of
+        the default behavior.

+      

+      The plugin understands the following options (the options object
+      will also be passed along to the hinting function, which may
+      understand additional options):
+      

+        
async: boolean

+        
When set to true, the hinting function's signature should
+        be (cm, callback, ?options), and the completion
+        interface will only be popped up when the hinting function
+        calls the callback, passing it the object holding the
+        completions.

+        
completeSingle: boolean

+        
Determines whether, when only a single completion is
+        available, it is completed without showing the dialog.
+        Defaults to true.

+        
alignWithWord: boolean

+        
Whether the pop-up should be horizontally aligned with the
+        start of the word (true, default), or with the cursor (false).

+        
closeOnUnfocus: boolean

+        
When enabled (which is the default), the pop-up will close
+        when the editor is unfocused.

+        
customKeys: keymap

+        
Allows you to provide a custom keymap of keys to be active
+        when the pop-up is active. The handlers will be called with an
+        extra argument, a handle to the completion menu, which
+        has moveFocus(n), setFocus(n), pick(),
+        and close() methods (see the source for details),
+        that can be used to change the focused element, pick the
+        current element or close the menu.

+        
extraKeys: keymap

+        
Like customKeys above, but the bindings will
+        be added to the set of default bindings, instead of replacing
+        them.

+      

+      The following events will be fired on the completions object
+      during completion:
+      

+        
"shown" ()

+        
Fired when the pop-up is shown.

+        
"select" (completion, Element)

+        
Fired when a completion is selected. Passed the completion
+        value (string or object) and the DOM node that represents it
+        in the menu.

+        
"close" ()

+        
Fired when the completion is finished.

+      

+      This addon depends styles
+      from addon/hint/show-hint.css. Check
+      out the demo for an
+      example.

+
+      
hint/javascript-hint.js

+      
Defines a simple hinting function for JavaScript
+      (CodeMirror.hint.javascript) and CoffeeScript
+      (CodeMirror.hint.coffeescript) code. This will
+      simply use the JavaScript environment that the editor runs in as
+      a source of information about objects and their properties.

+
+      
hint/xml-hint.js

+      
Defines CodeMirror.hint.xml, which produces
+      hints for XML tagnames, attribute names, and attribute values,
+      guided by a schemaInfo option (a property of the
+      second argument passed to the hinting function, or the third
+      argument passed to CodeMirror.showHint).
The
+      schema info should be an object mapping tag names to information
+      about these tags, with optionally a "!top" property
+      containing a list of the names of valid top-level tags. The
+      values of the properties should be objects with optional
+      properties children (an array of valid child
+      element names, omit to simply allow all tags to appear)
+      and attrs (an object mapping attribute names
+      to null for free-form attributes, and an array of
+      valid values for restricted
+      attributes). Demo
+      here.

+
+      
hint/html-hint.js

+      
Provides schema info to
+      the xml-hint addon for HTML
+      documents. Defines a schema
+      object CodeMirror.htmlSchema that you can pass to
+      as a schemaInfo option, and
+      a CodeMirror.hint.html hinting function that
+      automatically calls CodeMirror.hint.xml with this
+      schema data. See
+      the demo.

+
+      
hint/python-hint.js

+      
A very simple hinting function for Python code.
+      Defines CodeMirror.hint.python.

+
+      
hint/anyword-hint.js

+      
A very simple hinting function
+      (CodeMirror.hint.anyword) that simply looks for
+      words in the nearby code and completes to those. Takes two
+      optional options, word, a regular expression that
+      matches words (sequences of one or more character),
+      and range, which defines how many lines the addon
+      should scan when completing (defaults to 500).

+
+      
match-highlighter.js

+      
Adds a highlightSelectionMatches option that
+      can be enabled to highlight all instances of a currently
+      selected word. Can be set either to true or to an object
+      containing the following options: minChars, for the
+      minimum amount of selected characters that triggers a highlight
+      (default 2), style, for the style to be used to
+      highlight the matches (default "matchhighlight",
+      which will correspond to CSS
+      class cm-matchhighlight),
+      and showToken which can be set to true
+      or to a regexp matching the characters that make up a word. When
+      enabled, it causes the current word to be highlighted when
+      nothing is selected (defaults to off).
+      Demo here.

+
+      
lint/lint.js

+      
Defines an interface component for showing linting warnings,
+      with pluggable warning sources
+      (see json-lint.js
+      and javascript-lint.js
+      in the same directory). Defines a lint option that
+      can be set to a warning source (for
+      example CodeMirror.lint.javascript), or
+      to true, in which
+      case getHelper with
+      type "lint" is used to determined a validator
+      function. Depends on addon/lint/lint.css. A demo
+      can be found here.

+
+      
selection/mark-selection.js

+      
Causes the selected text to be marked with the CSS class
+      CodeMirror-selectedtext when the styleSelectedText option
+      is enabled. Useful to change the colour of the selection (in addition to the background),
+      like in this demo.

+
+      
selection/active-line.js

+      
Defines a styleActiveLine option that, when enabled,
+      gives the wrapper of the active line the class CodeMirror-activeline,
+      and adds a background with the class CodeMirror-activeline-background.
+      is enabled. See the demo.

+
+      
edit/closetag.js

+      
Provides utility functions for adding automatic tag closing
+      to XML modes. See
+      the demo.

+
+      
mode/loadmode.js

+      
Defines a CodeMirror.requireMode(modename,
+      callback) function that will try to load a given mode and
+      call the callback when it succeeded. You'll have to
+      set CodeMirror.modeURL to a string that mode paths
+      can be constructed from, for
+      example "mode/%N/%N.js"—the %N's will
+      be replaced with the mode name. Also
+      defines CodeMirror.autoLoadMode(instance, mode),
+      which will ensure the given mode is loaded and cause the given
+      editor instance to refresh its mode when the loading
+      succeeded. See the demo.

+
+      
edit/continuecomment.js

+      
Adds an continueComments option, which can be
+      set to true to have the editor prefix new lines inside C-like
+      block comments with an asterisk when Enter is pressed. It can
+      also be set to a string in order to bind this functionality to a
+      specific key..

+
+      
display/placeholder.js

+      
Adds a placeholder option that can be used to
+      make text appear in the editor when it is empty and not focused.
+      Also gives the editor a CodeMirror-empty CSS class
+      whenever it doesn't contain any text.
+      See the demo.

+
+      
merge/merge.js

+      
Implements an interface for merging changes, using either a
+      2-way or a 3-way view. The CodeMirror.MergeView
+      constructor takes arguments similar to
+      the CodeMirror
+      constructor, first a node to append the interface to, and then
+      an options object. Two extra optional options are
+      recognized, origLeft and origRight,
+      which may be strings that provide original versions of the
+      document, which will be shown to the left and right of the
+      editor in non-editable CodeMirror instances. The merge interface
+      will highlight changes between the editable document and the
+      original(s) (demo).

+    

+
+    
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 in 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 are encouraged to use the
+    'standard' names defined in the themes (without
+    the cm- prefix). If that fails, it is also possible
+    to come up with your own and write your own CSS theme file.

+
+    
The stream object that's passed
+    to token 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() → string

+      
Returns the next character in the stream without advancing
+      it. Will return an null at the end of the
+      line.

+      
next() → string

+      
Returns the next character in the stream and advances it.
+      Also returns null when no more characters are
+      available.

+
+      
eat(match: string|regexp|function(char: string) → boolean) → string

+      
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: string|regexp|function(char: string) → boolean) → 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: string) → 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: string, ?consume: boolean, ?caseFold: boolean) → boolean

+      
match(pattern: regexp, ?consume: boolean) → array<string>

+      
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: integer)

+      
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.

+      
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.

+
+    
If you want your mode to provide smart indentation
+    (through the indentLine
+    method and the indentAuto
+    and newlineAndIndent commands, to which keys can be
+    bound), 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. An indentation method may
+    return CodeMirror.Pass to indicate that it
+    could not come up with a precise indentation.

+
+    
To work well with
+    the commenting addon, a mode may
+    define lineComment (string that starts a line
+    comment), blockCommentStart, blockCommentEnd
+    (strings that start and end block comments),
+    and blockCommentLead (a string to put at the start of
+    continued lines in a block comment). All of these are
+    optional.

+
+    
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,
+    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.

+
+    
In a nested mode, it is recommended to add an
+    extra methods, innerMode which, given a state object,
+    returns a {state, mode} object with the inner mode
+    and its state for the current position. These are used by utility
+    scripts such as the tag closer to
+    get context information. Use the CodeMirror.innerMode
+    helper function to, starting from a mode and a state, recursively
+    walk down to the innermost mode and 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.

+
+    
It is possible, and encouraged, 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.

+
+    
Sometimes, it is useful to add or override mode
+    object properties from external code.
+    The CodeMirror.extendMode can be used to add
+    properties to mode objects produced for a specific mode. Its first
+    argument is the name of the mode, its second an object that
+    specifies the properties that should be added. This is mostly
+    useful to add utilities that can later be looked
+    up through getMode.

+
+
+/* Reporting bugs
+   effectively */
+

+

+
+

+
+
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:

+
+
    
+  
  1. 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.
    2. 
+
+  
  2. 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.
    3. 
+
+  
  3. 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.
    4. 
+
+  
  4. 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.
    5. 
+
+  
  5. 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.
    6.

+    CodeMirror: Upgrading to v2.2
+    
+    
+  
+  
+
+
{ } CodeMirror

+
+

+
+
+/* Upgrading to
+   v2.2 */
+

+

+
+

+
+
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:

+
+
  extraKeys: {
+    "Ctrl-S": function(instance) { saveText(instance.getValue()); },
+    "Ctrl-/": "undo"
+  }

+
+
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.

+
+

+
+
+/* Upgrading to
+   version 3 */
+

+

+
+

+
+
Version 3 does not depart too much from 2.x API, and sites that use
+CodeMirror in a very simple way might be able to upgrade without
+trouble. But it does introduce a number of incompatibilities. Please
+at least skim this text before upgrading.

+
+
Note that version 3 drops full support for Internet
+Explorer 7. The editor will mostly work on that browser, but
+it'll be significantly glitchy.

+
+
DOM structure

+
+
This one is the most likely to cause problems. The internal
+structure of the editor has changed quite a lot, mostly to implement a
+new scrolling model.

+
+
Editor height is now set on the outer wrapper element (CSS
+class CodeMirror), not on the scroller element
+(CodeMirror-scroll).

+
+
Other nodes were moved, dropped, and added. If you have any code
+that makes assumptions about the internal DOM structure of the editor,
+you'll have to re-test it and probably update it to work with v3.

+
+
See the styling section of the
+manual for more information.

+
+
Gutter model

+
+
In CodeMirror 2.x, there was a single gutter, and line markers
+created with setMarker would have to somehow coexist with
+the line numbers (if present). Version 3 allows you to specify an
+array of gutters, by class
+name,
+use setGutterMarker
+to add or remove markers in individual gutters, and clear whole
+gutters
+with clearGutter.
+Gutter markers are now specified as DOM nodes, rather than HTML
+snippets.

+
+
The gutters no longer horizontally scrolls along with the content.
+The fixedGutter option was removed (since it is now the
+only behavior).

+
+
+<style>
+  /* Define a gutter style */
+  .note-gutter { width: 3em; background: cyan; }
+</style>
+<script>
+  // Create an instance with two gutters -- line numbers and notes
+  var cm = new CodeMirror(document.body, {
+    gutters: ["note-gutter", "CodeMirror-linenumbers"],
+    lineNumbers: true
+  });
+  // Add a note to line 0
+  cm.setGutterMarker(0, "note-gutter", document.createTextNode("hi"));
+</script>
+

+
+
Event handling

+
+
Most of the onXYZ options have been removed. The same
+effect is now obtained by calling
+the on method with a string
+identifying the event type. Multiple handlers can now be registered
+(and individually unregistered) for an event, and objects such as line
+handlers now also expose events. See the
+full list here.

+
+
(The onKeyEvent and onDragEvent options,
+which act more as hooks than as event handlers, are still there in
+their old form.)

+
+
+cm.on("change", function(cm, change) {
+  console.log("something changed! (" + change.origin + ")");
+});
+

+
+
markText method arguments

+
+
The markText method
+(which has gained some interesting new features, such as creating
+atomic and read-only spans, or replacing spans with widgets) no longer
+takes the CSS class name as a separate argument, but makes it an
+optional field in the options object instead.

+
+
+// Style first ten lines, and forbid the cursor from entering them
+cm.markText({line: 0, ch: 0}, {line: 10, ch: 0}, {
+  className: "magic-text",
+  inclusiveLeft: true,
+  atomic: true
+});
+

+
+
Line folding

+
+
The interface for hiding lines has been
+removed. markText can
+now be used to do the same in a more flexible and powerful way.

+
+
The folding script has been
+updated to use the new interface, and should now be more robust.

+
+
+// Fold a range, replacing it with the text "??"
+var range = cm.markText({line: 4, ch: 2}, {line: 8, ch: 1}, {
+  replacedWith: document.createTextNode("??"),
+  // Auto-unfold when cursor moves into the range
+  clearOnEnter: true
+});
+// Get notified when auto-unfolding
+CodeMirror.on(range, "clear", function() {
+  console.log("boom");
+});
+

+
+
Line CSS classes

+
+
The setLineClass method has been replaced
+by addLineClass
+and removeLineClass,
+which allow more modular control over the classes attached to a line.

+
+
+var marked = cm.addLineClass(10, "background", "highlighted-line");
+setTimeout(function() {
+  cm.removeLineClass(marked, "background", "highlighted-line");
+});
+

+
+
Position properties

+
+
All methods that take or return objects that represent screen
+positions now use {left, top, bottom, right} properties
+(not always all of them) instead of the {x, y, yBot} used
+by some methods in v2.x.

+
+
Affected methods
+are cursorCoords, charCoords, coordsChar,
+and getScrollInfo.

+
+
Bracket matching no longer in core

+
+
The matchBrackets
+option is no longer defined in the core editor.
+Load addon/edit/matchbrackets.js to enable it.

+
+
Mode management

+
+
The CodeMirror.listModes
+and CodeMirror.listMIMEs functions, used for listing
+defined modes, are gone. You are now encouraged to simply
+inspect CodeMirror.modes (mapping mode names to mode
+constructors) and CodeMirror.mimeModes (mapping MIME
+strings to mode specs).

+
+
New features

+
+
Some more reasons to upgrade to version 3.

+
+
    
+  
  • Bi-directional text support. CodeMirror will now mostly do the
+  right thing when editing Arabic or Hebrew text.
    • 
+  
  • Arbitrary line heights. Using fonts with different heights
+  inside the editor (whether off by one pixel or fifty) is now
+  supported and handled gracefully.
    • 
+  
  • In-line widgets. See the demo
+  and the docs.
    • 
+  
  • Defining custom options
+  with CodeMirror.defineOption.
    •

+

+

+
+

+
+  
CodeMirror is a JavaScript component that
+  provides a code editor in the browser. When a mode is available for
+  the language you are coding in, it will color your code, and
+  optionally help with indentation.

+
+  
A rich programming API and a CSS
+  theming system are available for customizing CodeMirror to fit your
+  application, and extending it with new functionality.

+
+  

+
+    
Supported modes:

+
+

+
+  

+
+  
Getting the code

+
+  
All of CodeMirror is released under a MIT-style license. To get it, you can download
+  the latest
+  release or the current development
+  snapshot as zip files. To create a custom minified script file,
+  you can use the compression API.

+
+  
We use git for version control.
+  The main repository can be fetched in this way:

+
+  
git clone http://marijnhaverbeke.nl/git/codemirror

+
+  
CodeMirror can also be found on GitHub at marijnh/CodeMirror.
+  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.

+

+  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
+  a series of
+  posts on CodeMirror on my blog, and the
+  old overview of the editor
+  internals.
+  The source code
+  itself is, for the most part, also very readable.

+
+  
Support and bug reports

+
+  
Community discussion, questions, and informal bug reporting is
+  done on
+  the CodeMirror
+  Google group. There is a separate
+  group, CodeMirror-announce,
+  which is lower-volume, and is only used for major announcements—new
+  versions and such. These will be cross-posted to both groups, so you
+  don't need to subscribe to both.

+
+  
Though bug reports through e-mail are responded to, the preferred
+  way to report bugs is to use
+  the GitHub
+  issue tracker. Before reporting a
+  bug, read these pointers. Also,
+  the issue tracker is for bugs, not requests for help.

+
+  
When none of these seem fitting, you can
+  simply e-mail the maintainer
+  directly.

+
+  
Supported browsers

+
+  
The following desktop browsers are able to run CodeMirror:

+
+  
    
+    
  • Firefox 3 or higher
    • 
+    
  • Chrome, any version
    • 
+    
  • Safari 5.2 or higher
    • 
+    
  • Opera 9 or higher (with some key-handling problems on OS X)
    • 
+    
  • Internet Explorer 8 or higher
    
+    
  • Internet Explorer 7 (standards mode) is usable, but buggy. It
+    has a z-index
+    bug that prevents CodeMirror from working properly.
    • 
+  

+
+  
Note that CodeMirror is only supported in
+  standards mode. So not quirks mode,
+  but also not the quasi-standards mode that IE gives you
+  when you specify a transitional doctype. Simply using the
+  HTML5-style <!doctype html> is recommended.
+
+  
Mobile browsers mostly kind of work, but, because of limitations
+  and their fundamentally different UI assumptions, show a lot of
+  quirks that are hard to work around.

+
+  
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 support contracts exist in two
+  forms—basic at €100 per month,
+  and premium at €500 per
+  month. Contact me for further
+  information.

CodeMirror: APL mode

+
+

+
+    
+
+    
Simple mode that tries to handle APL as well as it can.

+    
It attempts to label functions/operators based upon
+    monadic/dyadic usage (but this is far from fully fleshed out).
+    This means there are meaningful classnames so hover states can
+    have popups etc.

+
+    
MIME types defined: text/apl (APL code)

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.

+
+    
MIME types defined: text/x-csrc
+    (C code), text/x-c++src (C++
+    code), text/x-java (Java
+    code), text/x-csharp (C#).

Handles AT&T assembler syntax (more specifically this handles
+        the GNU Assembler (gas) syntax.)
+        It takes a single optional configuration parameter:
+        architecture, which can be one of "ARM",
+        "ARMv6" or "x86".
+        Including the parameter adds syntax for the registers and special
+        directives for the supplied architecture.

CodeMirror: HTML mixed mode

+    

+    
+
+    
The HTML mixed mode depends on the XML, JavaScript, and CSS modes.

+
+    
It takes an optional mode configuration
+    option, scriptTypes, which can be used to add custom
+    behavior for specific <script type="..."> tags. If
+    given, it should hold an array of {matches, mode}
+    objects, where matches is a string or regexp that
+    matches the script type, and mode is
+    either null, for script types that should stay in
+    HTML mode, or a mode
+    spec corresponding to the mode that should be used for the
+    script.

+
+    
MIME types defined: text/html
+    (redefined, only takes effect if you load this parser after the
+    XML parser).

CodeMirror: JavaScript mode

+
+

+
+    
+
+    

+      JavaScript mode supports a two configuration
+      options:
+      
    
+        
  • json which will set the mode to expect JSON
+        data rather than a JavaScript program.
    • 
+        
  • typescript which will activate additional
+        syntax highlighting and some other things for TypeScript code
+        (demo).
    • 
+        
  • statementIndent which (given a number) will
+        determine the amount of indentation to use for statements
+        continued on a new line.
    • 
+      

+    

+
+    
MIME types defined: text/javascript, application/json, text/typescript, application/typescript.

+    
    
+      
  • version - 2/3 - The version of Python to recognize.  Default is 2.
    • 
+      
  • singleLineStringErrors - true/false - If you have a single-line string that is not terminated at the end of the line, this will show subsequent lines as errors if true, otherwise it will consider the newline as the end of the string. Default is false.
    • 
+    

+    
Advanced Configuration Options:

+    
Usefull for superset of python syntax like Enthought enaml, IPython magics and  questionmark help

+    
    
+      
  • singleOperators - RegEx - Regular Expression for single operator matching,  default : 
    ^[\\+\\-\\*/%&|\\^~<>!]

CodeMirror: Smarty mixed mode

+    

+
+    
+
+    
The Smarty mixed mode depends on the Smarty and HTML mixed modes. HTML
+    mixed mode itself depends on XML, JavaScript, and CSS modes.

+
+    
It takes the same options, as Smarty and HTML mixed modes.

+
+

+  How Properties of Mime Types are used by SQL Mode
+  =================================================
+
+  keywords:
+    A list of keywords you want to be highlighted.
+  functions:
+    A list of function names you want to be highlighted.
+  builtin:
+    A list of builtin types you want to be highlighted (if you want types to be of class "builtin" instead of "keyword").
+  operatorChars:
+    All characters that must be handled as operators.
+  client:
+    Commands parsed and executed by the client (not the server).
+  support:
+    A list of supported syntaxes which are not common, but are supported by more than 1 DBMS.
+    * ODBCdotTable: .tableName
+    * zerolessFloat: .1
+    * doubleQuote
+    * nCharCast: N'string'
+    * charsetCast: _utf8'string'
+    * commentHash: use # char for comments
+    * commentSlashSlash: use // for comments
+    * commentSpaceRequired: require a space after -- for comments
+  atoms:
+    Keywords that must be highlighted as atoms,. Some DBMS's support more atoms than others:
+    UNKNOWN, INFINITY, UNDERFLOW, NaN...
+  dateSQL:
+    Used for date/time SQL standard syntax, because not all DBMS's support same temporal types.

    CodeMirror: XML mode

+

    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.

+  // advancing the input stream and returning an AST node. Precedence
+  // of constructs (for example, the fact that `!x[1]` means `!(x[1])`
+  // instead of `(!x)[1]` is handled by the fact that the parser
+  // function that parses unary prefix operators is called first, and
+  // in turn calls the function that parses `[]` subscripts — that
+  // way, it'll receive the node for `x[1]` already parsed, and wraps
+  // *that* in the unary operator node.
+  //
+  // Acorn uses an [operator precedence parser][opp] to handle binary
+  // operator precedence, because it is much more compact than using
+  // the technique outlined above, which uses different, nesting
+  // functions to specify precedence, for all of the ten binary
+  // precedence levels that JavaScript defines.

+/***********************************************************************
+
+  A JavaScript tokenizer / parser / beautifier / compressor.
+
+  This version is suitable for Node.js.  With minimal changes (the
+  exports stuff) it should work on any JS platform.
+
+  This file contains the tokenizer/parser.  It is a port to JavaScript
+  of parse-js [1], a JavaScript parser library written in Common Lisp
+  by Marijn Haverbeke.  Thank you Marijn!
+
+  [1] http://marijn.haverbeke.nl/parse-js/
+
+  Exported functions:
+
+    - tokenizer(code) -- returns a function.  Call the returned
+      function to fetch the next token.
+
+    - parse(code) -- returns an AST of the given JavaScript code.

+ * Helper to test CodeMirror highlighting modes. It pretty prints output of the
+ * highlighter and can check against expected styles.
+ *
+ * Mode tests are registered by calling test.mode(testName, mode,
+ * tokens), where mode is a mode object as returned by
+ * CodeMirror.getMode, and tokens is an array of lines that make up
+ * the test.
+ *
+ * These lines are strings, in which styled stretches of code are
+ * enclosed in brackets `[]`, and prefixed by their style. For
+ * example, `[keyword if]`. Brackets in the code itself must be
+ * duplicated to prevent them from being interpreted as token
+ * boundaries. For example `a[[i]]` for `a[i]`. If a token has
+ * multiple styles, the styles must be separated by ampersands, for
+ * example `[tag&error ]`.
+ *
+ * See the test.js files in the css, markdown, gfm, and stex mode
+ * directories for examples.
