# CodeMirror [![Build Status](https://secure.travis-ci.org/marijnh/CodeMirror.png?branch=master)](http://travis-ci.org/marijnh/CodeMirror)
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.
The project page is http://codemirror.net
The manual is at http://codemirror.net/doc/manual.html

// Compression helper for CodeMirror
//
// Example:
//
// bin/compress codemirror runmode javascript xml
//
// Will take lib/codemirror.js, lib/util/runmode.js,
// mode/javascript/javascript.js, and mode/xml/xml.js, run them though
// the online minifier at http://marijnhaverbeke.nl/uglifyjs, and spit
// out the result.

// bin/compress codemirror --local /path/to/bin/UglifyJS

//
// Script files are specified without .js ending. Prefixing them with
// their full (local) path is optional. So you may say lib/codemirror
// or mode/xml/xml to be more precise. In fact, even the .js suffix
// may be speficied, if wanted.

<p>The emacs keybindings are enabled by
including <a href="../keymap/emacs.js">keymap/emacs.js</a> and setting
the <code>keyMap</code> option to <code>"emacs"</code>. Because
CodeMirror's internal API is quite different from Emacs, they are only
a loose approximation of actual emacs bindings, though.</p>
<p>Also note that a lot of browsers disallow certain keys from being
captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the
result that idiomatic use of Emacs keys will constantly close your tab
or open a new window.</p>

<p>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 <strong>Compress</strong> to download the minified script
file.</p>

<strong>Topic:</strong> JavaScript, code editor implementation<br>
<strong>Author:</strong> Marijn Haverbeke<br>
<strong>Date:</strong> March 2nd 2011 (updated November 13th 2011)
</p>
<p>This is a followup to
my <a href="http://codemirror.net/story.html">Brutal Odyssey to the
Dark Side of the DOM Tree</a> 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.</p>
<p>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 <a href="http://googlecode.blogspot.com/2011/01/make-quick-fixes-quicker-on-google.html">Google
code's project hosting</a>. It works, and it's being used widely.</a>
<p>Still, I did not start replacing it because I was bored. CodeMirror
1 was heavily reliant on <code>designMode</code>
or <code>contentEditable</code> (depending on the browser). Neither of
these are well specified (HTML5 tries
to <a href="http://www.w3.org/TR/html5/editing.html#contenteditable">specify</a>
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.</p>
<p>Also, there is the fact that <code>designMode</code> (which seemed
to be less buggy than <code>contentEditable</code> 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.</p>
<p>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
<code>document.selection</code>, 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.</p>
<p>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 <a href="http://codemirror.net/story.html">story</a>), things
also kept breaking in newly released versions, requiring me to come up
with <em>new</em> scary hacks in order to keep up. This was starting
to lose its appeal.</p>
<h2 id="approach">General Approach</h2>
<p>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
<a href="http://ace.ajax.org">ACE</a> editor for inspiration on how to
approach this.</p>
<p>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 <a href="http://ymacs.org">Ymacs</a>) 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. <a href="#keymap" class="update">[see below for caveat]</a></p>
<p>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.</p>
<p>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 <code>onscroll</code>
event works almost the same on all browsers, and lends itself well to
displaying things only as they are scrolled into view.)</p>
<h2 id="input">Input</h2>
<p>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.</p>
<p>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.</p>
<p>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. <a class="update"
href="#keymap">[no longer the case]</a></p>
<p>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.</p>
<h2 id="selection">Selection</h2>
<p>Getting and setting the selection range of a textarea in modern
browsers is trivial—you just use the <code>selectionStart</code>
and <code>selectionEnd</code> 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.</p>
<p>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 <em>head</em>
and its <em>anchor</em> 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.</p>
<p>But not something that the browser selection APIs expose.</p>
<p>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.</p>
<p>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 <em>real</em>
selection.</p>
<p>In short, scary hacks could not be avoided entirely in CodeMirror
2.</p>
<p>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.</p>
<h2 id="update">Intelligent Updating</h2>
<p>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.</p>
<p>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.</p>
<p>CodeMirror uses a concept of <em>operations</em>, 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 <code>operation</code> that accepts a function, and returns
another function that wraps the given function as an operation.</p>
<p>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.</p>
<p>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.</p>
<p>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). <span class="update">[the full-refresh
algorithm was dropped, it wasn't really faster than the patching
one]</span></p>
<p>All updating uses <code>innerHTML</code> 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, <a href="manual.html#markText">marking</a>, 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 <code>innerHTML</code> update to do the refresh.</p>
<h2 id="parse">Parsers can be Simple</h2>
<p>When I wrote CodeMirror 1, I
thought <a href="http://codemirror.net/story.html#parser">interruptable
parsers</a> were a hugely scary and complicated thing, and I used a
bunch of heavyweight abstractions to keep this supposed complexity
under control: parsers
were <a href="http://bob.pythonmac.org/archives/2005/07/06/iteration-in-javascript/">iterators</a>
that consumed input from another iterator, and used funny
closure-resetting tricks to copy and resume themselves.</p>
<p>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.</p>
<p>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 <a href="manual.html#modeapi">mode API</a> 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.</p>
<p>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 <em>see</em> 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.</p>
<h2 id="summary">What Gives?</h2>
<p>Given all this, what can you expect from CodeMirror 2?</p>
<ul>
<li><strong>Small.</strong> the base library is
some <span class="update">45k</span> when minified
now, <span class="update">17k</span> when gzipped. It's smaller than
its own logo.</li>
<li><strong>Lightweight.</strong> 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.</li>
<li><strong>Huge document support.</strong> 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.</li>
<li><strong>Extended API.</strong> 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.</li>
<li><strong>Tab support.</strong> 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.</li>
<li><strong>Sane styling.</strong> <code>iframe</code> nodes aren't
really known for respecting document flow. Now that an editor instance
is a plain <code>div</code> 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 <a href="../demo/resize.html">want to</a>.</li>
</ul>
<p>On the downside, a CodeMirror 2 instance is <em>not</em> 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.</p>
<p id="changes" style="margin-top: 2em;"><span style="font-weight:
bold">[Updates from November 13th 2011]</span> 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.</p>
<h2 id="btree">Content Representation</h2>
<p>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 <code>memmove</code> of a
bunch of pointers, so it is cheap even for huge documents.</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<p>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.</p>
<h2 id="keymap">Keymaps</h2>
<p><a href="#approach">Above</a>, 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 <a href="#selection">hacks</a> 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.</p>
<p>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.</p>
<p>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.</p>
<p>The key event handlers now translate the key event into a string,
something like <code>Ctrl-Home</code> or <code>Shift-Cmd-R</code>, and
use that string to look up an action to perform. To make keybinding
customizable, this lookup goes through
a <a href="manual.html#option_keyMap">table</a>, 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 <code>Ctrl-F</code>, and which is also
used by the custom Emacs bindings).</p>
<p>A new
option <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
allows ad-hoc keybindings to be defined in a much nicer way than what
was possible with the
old <a href="manual.html#option_onKeyEvent"><code>onKeyEvent</code></a>
callback. You simply provide an object mapping key identifiers to
functions, instead of painstakingly looking at raw key events.</p>
<p>Built-in commands map to strings, rather than functions, for
example <code>"goLineUp"</code> 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 <code>CodeMirror.commands</code> object, which maps such commands
to functions.</p>
<p>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.</p>
<p>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 <code>input</code> when the
composing is finished, but many don't fire anything when the character
is updated <em>during</em> composition. So we poll, whenever the
editor is focused, to provide immediate updates of the display.</p>

<p>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:</p>
<ol>
<li>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.</li>
<li>Include information about <strong>the browser in which the
problem occurred</strong>. 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.</li>
<li>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.</li>
<li>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.</li>
<li>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 <a href="http://jsbin.com/ihunin/edit">jsbin.com</a>, enter
it there, press save, and include the resulting link in your bug
report.</li>

<pre>
/* Upgrading to
v2.2 */
</pre>
</div>
<div class="left">
<p>There are a few things in the 2.2 release that require some care
when upgrading.</p>
<h2>No more default.css</h2>
<p>The default theme is now included
in <a href="../lib/codemirror.css"><code>codemirror.css</code></a>, 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.)
<h2>Different key customization</h2>
<p>CodeMirror has moved to a system
where <a href="manual.html#option_keyMap">keymaps</a> are used to
bind behavior to keys. This means <a href="../demo/emacs.html">custom
bindings</a> are now possible.</p>
<p>Three options that influenced key
behavior, <code>tabMode</code>, <code>enterMode</code>,
and <code>smartHome</code>, are no longer supported. Instead, you can
provide custom bindings to influence the way these keys act. This is
done through the
new <a href="manual.html#option_extraKeys"><code>extraKeys</code></a>
option, which can hold an object mapping key names to functionality. A
simple example would be:</p>
<pre> extraKeys: {
"Ctrl-S": function(instance) { saveText(instance.getValue()); },
"Ctrl-/": "undo"
}</pre>
<p>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 <code>CodeMirror.commands</code> table, which
contains all the built-in editing commands, and can be inspected and
extended by external code.</p>
<p>By default, the <code>Home</code> key is bound to
the <code>"goLineStartSmart"</code> 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:</p>
<pre> extraKeys: {"Home": "goLineStart"}</pre>
<p>Similarly, <code>Enter</code> is bound
to <code>"newlineAndIndent"</code> 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 <code>false</code>:</p>
<pre> extraKeys: {"Enter": false}</pre>
<p>The same works for <code>Tab</code>. If you don't want CodeMirror
to handle it, bind it to <code>false</code>. The default behaviour is
to indent the current line more (<code>"indentMore"</code> command),
and indent it less when shift is held (<code>"indentLess"</code>).
There are also <code>"indentAuto"</code> (smart indent)
and <code>"insertTab"</code> commands provided for alternate
behaviors. Or you can write your own handler function to do something
different altogether.</p>
<h2>Tabs</h2>
<p>Handling of tabs changed completely. The display width of tabs can
now be set with the <code>tabSize</code> option, and tabs can
be <a href="../demo/visibletabs.html">styled</a> by setting CSS rules
for the <code>cm-tab</code> class.</p>
<p>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 <code>tabSize: 8</code> in your options.</p>

<h2 id="code">Getting the code</h2>
<p>All of CodeMirror is released under a <a
href="LICENSE">MIT-style</a> license. To get it, you can download
the <a href="http://codemirror.net/codemirror.zip">latest
release</a> or the current <a
href="http://codemirror.net/codemirror-latest.zip">development
snapshot</a> as zip files. To create a custom minified script file,
you can use the <a href="doc/compress.html">compression API</a>.</p>
<p>We use <a href="http://git-scm.com/">git</a> for version control.
The main repository can be fetched in this way:</p>
<pre class="code">git clone http://marijnhaverbeke.nl/git/codemirror</pre>
<p>CodeMirror can also be found on GitHub at <a
href="http://github.com/marijnh/CodeMirror">marijnh/CodeMirror</a>.
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.</p>
<h2 id="documention">Documentation</h2>
<p>The <a href="doc/manual.html">manual</a> is your first stop for
learning how to use this library. It starts with a quick explanation
of how to use the editor, and then describes the API in detail.</p>
<p>For those who want to learn more about the code, there is
an <a href="doc/internals.html">overview of the internals</a> available.
The <a href="http://github.com/marijnh/CodeMirror">source code</a>
itself is, for the most part, also well commented.</p>
<h2 id="support">Support and bug reports</h2>
<p>Community discussion, questions, and informal bug reporting is
done on
the <a href="http://groups.google.com/group/codemirror">CodeMirror
Google group</a>. There is a separate
group, <a href="http://groups.google.com/group/codemirror-announce">CodeMirror-announce</a>,
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.</p>
<p>Though bug reports through e-mail are responded to, the preferred
way to report bugs is to use
the <a href="http://github.com/marijnh/CodeMirror/issues">GitHub
issue tracker</a>. Before reporting a
bug, <a href="doc/reporting.html">read these pointers</a>. Also,
the issue tracker is for <em>bugs</em>, not requests for help.</p>
<p>When none of these seem fitting, you can
simply <a href="mailto:marijnh@gmail.com">e-mail the maintainer</a>
directly.</p>
<h2 id="supported">Supported browsers</h2>
<p>The following <em>desktop</em> browsers are able to run CodeMirror:</p>
<ul>
<li>Firefox 2 or higher</li>
<li>Chrome, any version</li>
<li>Safari 3 or higher</li>
<li>Opera 9 or higher (with some key-handling problems on OS X)</li>
<li>Internet Explorer 7 or higher in standards mode<br>
<em>(So not quirks mode. But quasi-standards mode with a
transitional doctype is also flaky. <code>&lt;!doctype
html></code> is recommended.)</em></li>
</ul>
<p>I am not actively testing against every new browser release, and
vendors have a habit of introducing bugs all the time, so I am
relying on the community to tell me when something breaks.
See <a href="#support">here</a> for information on how to contact
me.</p>
<p>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.</p>
<h2 id="commercial">Commercial support</h2>
<p>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.</p>
<ul>
<li>You'll be funding further work on CodeMirror.</li>
<li>You ensure that you get a quick response when you have a
problem, even when I am otherwise busy.</li>
</ul>
<p>CodeMirror support contracts exist in two
forms—<strong>basic</strong> at €100 per month,
and <strong>premium</strong> at €500 per
month. <a href="mailto:marijnh@gmail.com">Contact me</a> for further
information.</p>

/**

* also complete "</" if a matching start tag is found. It will correctly ignore signal
* characters for empty tags, comments, CDATA, etc.
*
* The function depends on internal parser state to identify tags. It is compatible with the
* following CodeMirror modes and will ignore all others:
* - htmlmixed
* - xml
*
* See demos/closetag.html for a usage example.

/** A template trait for traversable collections of type `Traversable[A]`.
*
* $traversableInfo
* @define mutability
* @define traversableInfo
* This is a base trait of all kinds of $mutability Scala collections. It
* implements the behavior common to all collections, in terms of a method
* `foreach` with signature:
* {{{
* def foreach[U](f: Elem => U): Unit
* }}}
* Collection classes mixing in this trait provide a concrete
* `foreach` method which traverses all the
* elements contained in the collection, applying a given function to each.
* They also need to provide a method `newBuilder`
* which creates a builder for collections of the same kind.
*
* A traversable class might or might not have two properties: strictness
* and orderedness. Neither is represented as a type.
*
* The instances of a strict collection class have all their elements
* computed before they can be used as values. By contrast, instances of
* a non-strict collection class may defer computation of some of their
* elements until after the instance is available as a value.
* A typical example of a non-strict collection class is a
* <a href="../immutable/Stream.html" target="ContentFrame">
* `scala.collection.immutable.Stream`</a>.
* A more general class of examples are `TraversableViews`.
*
* If a collection is an instance of an ordered collection class, traversing
* its elements with `foreach` will always visit elements in the
* same order, even for different runs of the program. If the class is not
* ordered, `foreach` can visit elements in different orders for
* different runs (but it will keep the same order in the same run).'
*
* A typical example of a collection class which is not ordered is a
* `HashMap` of objects. The traversal order for hash maps will
* depend on the hash codes of its elements, and these hash codes might
* differ from one run to the next. By contrast, a `LinkedHashMap`
* is ordered because it's `foreach` method visits elements in the
* order they were inserted into the `HashMap`.

* @tparam Repr the type of the actual collection containing the elements.

//
// rule** or **ruleset:
// A selector + braces combo, or an at-rule.
//
// declaration block:
// A sequence of declarations.
//
// declaration:
// A property + colon + value combo.
//
// property value:
// The entire value of a property.
//
// component value:
// A single piece of a property value. Like the 5px in
// text-shadow: 0 0 5px blue;. Can also refer to things that are
// multiple terms, like the 1-4 terms that make up the background-size
// portion of the background shorthand.
//
// term:
// The basic unit of author-facing CSS, like a single number (5),

//
//
// simple selector:
// A single atomic selector, like a type selector, an attr selector, a

// One or more simple selectors without a combinator. div.example is
// compound, div > .example is not.
//
// complex selector:
// One or more compound selectors chained with combinators.
//
// combinator:
// The parts of selectors that express relationships. There are four

GitHub Flavored Markdown
========================
Everything from markdown plus GFM features:
## URL autolinking
Underscores_are_allowed_between_words.
## Fenced code blocks (and syntax highlighting)
```javascript
for (var i = 0; i &lt; items.length; i++) {
console.log(items[i], i); // log them
}
```
## A bit of GitHub spice
