+ (through innerHTML).

+ Topic: JavaScript, code editor implementation
+ Author: Marijn Haverbeke
+ Date: March 2nd 2011 (updated November 13th 2011)
+
+
+
Caution: this text was written briefly after
+version 2 was initially written. It no longer (even including the
+update at the bottom) fully represents the current implementation. I'm
+leaving it here as a historic document. For more up-to-date
+information, look at the entries
+tagged cm-internals
+on my blog.
+
+
This is a followup to
+my Brutal Odyssey to the
+Dark Side of the DOM Tree story. That one describes the
+mind-bending process of implementing (what would become) CodeMirror 1.
+This one describes the internals of CodeMirror 2, a complete rewrite
+and rethink of the old code base. I wanted to give this piece another
+Hunter Thompson copycat subtitle, but somehow that would be out of
+place—the process this time around was one of straightforward
+engineering, requiring no serious mind-bending whatsoever.
+
+
So, what is wrong with CodeMirror 1? I'd estimate, by mailing list
+activity and general search-engine presence, that it has been
+integrated into about a thousand systems by now. The most prominent
+one, since a few weeks,
+being Google
+code's project hosting. It works, and it's being used widely.
+
+
Still, I did not start replacing it because I was bored. CodeMirror
+1 was heavily reliant on designMode
+or contentEditable (depending on the browser). Neither of
+these are well specified (HTML5 tries
+to specify
+their basics), and, more importantly, they tend to be one of the more
+obscure and buggy areas of browser functionality—CodeMirror, by using
+this functionality in a non-typical way, was constantly running up
+against browser bugs. WebKit wouldn't show an empty line at the end of
+the document, and in some releases would suddenly get unbearably slow.
+Firefox would show the cursor in the wrong place. Internet Explorer
+would insist on linkifying everything that looked like a URL or email
+address, a behaviour that can't be turned off. Some bugs I managed to
+work around (which was often a frustrating, painful process), others,
+such as the Firefox cursor placement, I gave up on, and had to tell
+user after user that they were known problems, but not something I
+could help.
+
+
Also, there is the fact that designMode (which seemed
+to be less buggy than contentEditable in Webkit and
+Firefox, and was thus used by CodeMirror 1 in those browsers) requires
+a frame. Frames are another tricky area. It takes some effort to
+prevent getting tripped up by domain restrictions, they don't
+initialize synchronously, behave strangely in response to the back
+button, and, on several browsers, can't be moved around the DOM
+without having them re-initialize. They did provide a very nice way to
+namespace the library, though—CodeMirror 1 could freely pollute the
+namespace inside the frame.
+
+
Finally, working with an editable document means working with
+selection in arbitrary DOM structures. Internet Explorer (8 and
+before) has an utterly different (and awkward) selection API than all
+of the other browsers, and even among the different implementations of
+document.selection, details about how exactly a selection
+is represented vary quite a bit. Add to that the fact that Opera's
+selection support tended to be very buggy until recently, and you can
+imagine why CodeMirror 1 contains 700 lines of selection-handling
+code.
+
+
And that brings us to the main issue with the CodeMirror 1
+code base: The proportion of browser-bug-workarounds to real
+application code was getting dangerously high. By building on top of a
+few dodgy features, I put the system in a vulnerable position—any
+incompatibility and bugginess in these features, I had to paper over
+with my own code. Not only did I have to do some serious stunt-work to
+get it to work on older browsers (as detailed in the
+previous story), things
+also kept breaking in newly released versions, requiring me to come up
+with new scary hacks in order to keep up. This was starting
+to lose its appeal.
+
+
General Approach
+
+
What CodeMirror 2 does is try to sidestep most of the hairy hacks
+that came up in version 1. I owe a lot to the
+ACE editor for inspiration on how to
+approach this.
+
+
I absolutely did not want to be completely reliant on key events to
+generate my input. Every JavaScript programmer knows that key event
+information is horrible and incomplete. Some people (most awesomely
+Mihai Bazon with Ymacs) have been able
+to build more or less functioning editors by directly reading key
+events, but it takes a lot of work (the kind of never-ending, fragile
+work I described earlier), and will never be able to properly support
+things like multi-keystoke international character
+input. [see below for caveat]
+
+
So what I do is focus a hidden textarea, and let the browser
+believe that the user is typing into that. What we show to the user is
+a DOM structure we built to represent his document. If this is updated
+quickly enough, and shows some kind of believable cursor, it feels
+like a real text-input control.
+
+
Another big win is that this DOM representation does not have to
+span the whole document. Some CodeMirror 1 users insisted that they
+needed to put a 30 thousand line XML document into CodeMirror. Putting
+all that into the DOM takes a while, especially since, for some
+reason, an editable DOM tree is slower than a normal one on most
+browsers. If we have full control over what we show, we must only
+ensure that the visible part of the document has been added, and can
+do the rest only when needed. (Fortunately, the onscroll
+event works almost the same on all browsers, and lends itself well to
+displaying things only as they are scrolled into view.)
+
+
Input
+
+
ACE uses its hidden textarea only as a text input shim, and does
+all cursor movement and things like text deletion itself by directly
+handling key events. CodeMirror's way is to let the browser do its
+thing as much as possible, and not, for example, define its own set of
+key bindings. One way to do this would have been to have the whole
+document inside the hidden textarea, and after each key event update
+the display DOM to reflect what's in that textarea.
+
+
That'd be simple, but it is not realistic. For even medium-sized
+document the editor would be constantly munging huge strings, and get
+terribly slow. What CodeMirror 2 does is put the current selection,
+along with an extra line on the top and on the bottom, into the
+textarea.
+
+
This means that the arrow keys (and their ctrl-variations), home,
+end, etcetera, do not have to be handled specially. We just read the
+cursor position in the textarea, and update our cursor to match it.
+Also, copy and paste work pretty much for free, and people get their
+native key bindings, without any special work on my part. For example,
+I have emacs key bindings configured for Chrome and Firefox. There is
+no way for a script to detect this. [no longer the case]
+
+
Of course, since only a small part of the document sits in the
+textarea, keys like page up and ctrl-end won't do the right thing.
+CodeMirror is catching those events and handling them itself.
+
+
Selection
+
+
Getting and setting the selection range of a textarea in modern
+browsers is trivial—you just use the selectionStart
+and selectionEnd properties. On IE you have to do some
+insane stuff with temporary ranges and compensating for the fact that
+moving the selection by a 'character' will treat \r\n as a single
+character, but even there it is possible to build functions that
+reliably set and get the selection range.
+
+
But consider this typical case: When I'm somewhere in my document,
+press shift, and press the up arrow, something gets selected. Then, if
+I, still holding shift, press the up arrow again, the top of my
+selection is adjusted. The selection remembers where its head
+and its anchor are, and moves the head when we shift-move.
+This is a generally accepted property of selections, and done right by
+every editing component built in the past twenty years.
+
+
But not something that the browser selection APIs expose.
+
+
Great. So when someone creates an 'upside-down' selection, the next
+time CodeMirror has to update the textarea, it'll re-create the
+selection as an 'upside-up' selection, with the anchor at the top, and
+the next cursor motion will behave in an unexpected way—our second
+up-arrow press in the example above will not do anything, since it is
+interpreted in exactly the same way as the first.
+
+
No problem. We'll just, ehm, detect that the selection is
+upside-down (you can tell by the way it was created), and then, when
+an upside-down selection is present, and a cursor-moving key is
+pressed in combination with shift, we quickly collapse the selection
+in the textarea to its start, allow the key to take effect, and then
+combine its new head with its old anchor to get the real
+selection.
+
+
In short, scary hacks could not be avoided entirely in CodeMirror
+2.
+
+
And, the observant reader might ask, how do you even know that a
+key combo is a cursor-moving combo, if you claim you support any
+native key bindings? Well, we don't, but we can learn. The editor
+keeps a set known cursor-movement combos (initialized to the
+predictable defaults), and updates this set when it observes that
+pressing a certain key had (only) the effect of moving the cursor.
+This, of course, doesn't work if the first time the key is used was
+for extending an inverted selection, but it works most of the
+time.
+
+
Intelligent Updating
+
+
One thing that always comes up when you have a complicated internal
+state that's reflected in some user-visible external representation
+(in this case, the displayed code and the textarea's content) is
+keeping the two in sync. The naive way is to just update the display
+every time you change your state, but this is not only error prone
+(you'll forget), it also easily leads to duplicate work on big,
+composite operations. Then you start passing around flags indicating
+whether the display should be updated in an attempt to be efficient
+again and, well, at that point you might as well give up completely.
+
+
I did go down that road, but then switched to a much simpler model:
+simply keep track of all the things that have been changed during an
+action, and then, only at the end, use this information to update the
+user-visible display.
+
+
CodeMirror uses a concept of operations, which start by
+calling a specific set-up function that clears the state and end by
+calling another function that reads this state and does the required
+updating. Most event handlers, and all the user-visible methods that
+change state are wrapped like this. There's a method
+called operation that accepts a function, and returns
+another function that wraps the given function as an operation.
+
+
It's trivial to extend this (as CodeMirror does) to detect nesting,
+and, when an operation is started inside an operation, simply
+increment the nesting count, and only do the updating when this count
+reaches zero again.
+
+
If we have a set of changed ranges and know the currently shown
+range, we can (with some awkward code to deal with the fact that
+changes can add and remove lines, so we're dealing with a changing
+coordinate system) construct a map of the ranges that were left
+intact. We can then compare this map with the part of the document
+that's currently visible (based on scroll offset and editor height) to
+determine whether something needs to be updated.
+
+
CodeMirror uses two update algorithms—a full refresh, where it just
+discards the whole part of the DOM that contains the edited text and
+rebuilds it, and a patch algorithm, where it uses the information
+about changed and intact ranges to update only the out-of-date parts
+of the DOM. When more than 30 percent (which is the current heuristic,
+might change) of the lines need to be updated, the full refresh is
+chosen (since it's faster to do than painstakingly finding and
+updating all the changed lines), in the other case it does the
+patching (so that, if you scroll a line or select another character,
+the whole screen doesn't have to be
+re-rendered). [the full-refresh
+algorithm was dropped, it wasn't really faster than the patching
+one]
+
+
All updating uses innerHTML rather than direct DOM
+manipulation, since that still seems to be by far the fastest way to
+build documents. There's a per-line function that combines the
+highlighting, marking, and
+selection info for that line into a snippet of HTML. The patch updater
+uses this to reset individual lines, the refresh updater builds an
+HTML chunk for the whole visible document at once, and then uses a
+single innerHTML update to do the refresh.
+
+
Parsers can be Simple
+
+
When I wrote CodeMirror 1, I
+thought interruptable
+parsers were a hugely scary and complicated thing, and I used a
+bunch of heavyweight abstractions to keep this supposed complexity
+under control: parsers
+were iterators
+that consumed input from another iterator, and used funny
+closure-resetting tricks to copy and resume themselves.
+
+
This made for a rather nice system, in that parsers formed strictly
+separate modules, and could be composed in predictable ways.
+Unfortunately, it was quite slow (stacking three or four iterators on
+top of each other), and extremely intimidating to people not used to a
+functional programming style.
+
+
With a few small changes, however, we can keep all those
+advantages, but simplify the API and make the whole thing less
+indirect and inefficient. CodeMirror
+2's mode API uses explicit state
+objects, and makes the parser/tokenizer a function that simply takes a
+state and a character stream abstraction, advances the stream one
+token, and returns the way the token should be styled. This state may
+be copied, optionally in a mode-defined way, in order to be able to
+continue a parse at a given point. Even someone who's never touched a
+lambda in his life can understand this approach. Additionally, far
+fewer objects are allocated in the course of parsing now.
+
+
The biggest speedup comes from the fact that the parsing no longer
+has to touch the DOM though. In CodeMirror 1, on an older browser, you
+could see the parser work its way through the document,
+managing some twenty lines in each 50-millisecond time slice it got. It
+was reading its input from the DOM, and updating the DOM as it went
+along, which any experienced JavaScript programmer will immediately
+spot as a recipe for slowness. In CodeMirror 2, the parser usually
+finishes the whole document in a single 100-millisecond time slice—it
+manages some 1500 lines during that time on Chrome. All it has to do
+is munge strings, so there is no real reason for it to be slow
+anymore.
+
+
What Gives?
+
+
Given all this, what can you expect from CodeMirror 2?
+
+
+
+
Small. the base library is
+some 45k when minified
+now, 17k when gzipped. It's smaller than
+its own logo.
+
+
Lightweight. CodeMirror 2 initializes very
+quickly, and does almost no work when it is not focused. This means
+you can treat it almost like a textarea, have multiple instances on a
+page without trouble.
+
+
Huge document support. Since highlighting is
+really fast, and no DOM structure is being built for non-visible
+content, you don't have to worry about locking up your browser when a
+user enters a megabyte-sized document.
+
+
Extended API. Some things kept coming up in the
+mailing list, such as marking pieces of text or lines, which were
+extremely hard to do with CodeMirror 1. The new version has proper
+support for these built in.
+
+
Tab support. Tabs inside editable documents were,
+for some reason, a no-go. At least six different people announced they
+were going to add tab support to CodeMirror 1, none survived (I mean,
+none delivered a working version). CodeMirror 2 no longer removes tabs
+from your document.
+
+
Sane styling.iframe nodes aren't
+really known for respecting document flow. Now that an editor instance
+is a plain div element, it is much easier to size it to
+fit the surrounding elements. You don't even have to make it scroll if
+you do not want to.
+
+
+
+
On the downside, a CodeMirror 2 instance is not a native
+editable component. Though it does its best to emulate such a
+component as much as possible, there is functionality that browsers
+just do not allow us to hook into. Doing select-all from the context
+menu, for example, is not currently detected by CodeMirror.
+
+
[Updates from November 13th 2011] Recently, I've made
+some changes to the codebase that cause some of the text above to no
+longer be current. I've left the text intact, but added markers at the
+passages that are now inaccurate. The new situation is described
+below.
+
+
Content Representation
+
+
The original implementation of CodeMirror 2 represented the
+document as a flat array of line objects. This worked well—splicing
+arrays will require the part of the array after the splice to be
+moved, but this is basically just a simple memmove of a
+bunch of pointers, so it is cheap even for huge documents.
+
+
However, I recently added line wrapping and code folding (line
+collapsing, basically). Once lines start taking up a non-constant
+amount of vertical space, looking up a line by vertical position
+(which is needed when someone clicks the document, and to determine
+the visible part of the document during scrolling) can only be done
+with a linear scan through the whole array, summing up line heights as
+you go. Seeing how I've been going out of my way to make big documents
+fast, this is not acceptable.
+
+
The new representation is based on a B-tree. The leaves of the tree
+contain arrays of line objects, with a fixed minimum and maximum size,
+and the non-leaf nodes simply hold arrays of child nodes. Each node
+stores both the amount of lines that live below them and the vertical
+space taken up by these lines. This allows the tree to be indexed both
+by line number and by vertical position, and all access has
+logarithmic complexity in relation to the document size.
+
+
I gave line objects and tree nodes parent pointers, to the node
+above them. When a line has to update its height, it can simply walk
+these pointers to the top of the tree, adding or subtracting the
+difference in height from each node it encounters. The parent pointers
+also make it cheaper (in complexity terms, the difference is probably
+tiny in normal-sized documents) to find the current line number when
+given a line object. In the old approach, the whole document array had
+to be searched. Now, we can just walk up the tree and count the sizes
+of the nodes coming before us at each level.
+
+
I chose B-trees, not regular binary trees, mostly because they
+allow for very fast bulk insertions and deletions. When there is a big
+change to a document, it typically involves adding, deleting, or
+replacing a chunk of subsequent lines. In a regular balanced tree, all
+these inserts or deletes would have to be done separately, which could
+be really expensive. In a B-tree, to insert a chunk, you just walk
+down the tree once to find where it should go, insert them all in one
+shot, and then break up the node if needed. This breaking up might
+involve breaking up nodes further up, but only requires a single pass
+back up the tree. For deletion, I'm somewhat lax in keeping things
+balanced—I just collapse nodes into a leaf when their child count goes
+below a given number. This means that there are some weird editing
+patterns that may result in a seriously unbalanced tree, but even such
+an unbalanced tree will perform well, unless you spend a day making
+strangely repeating edits to a really big document.
+
+
Keymaps
+
+
Above, I claimed that directly catching key
+events for things like cursor movement is impractical because it
+requires some browser-specific kludges. I then proceeded to explain
+some awful hacks that were needed to make it
+possible for the selection changes to be detected through the
+textarea. In fact, the second hack is about as bad as the first.
+
+
On top of that, in the presence of user-configurable tab sizes and
+collapsed and wrapped lines, lining up cursor movement in the textarea
+with what's visible on the screen becomes a nightmare. Thus, I've
+decided to move to a model where the textarea's selection is no longer
+depended on.
+
+
So I moved to a model where all cursor movement is handled by my
+own code. This adds support for a goal column, proper interaction of
+cursor movement with collapsed lines, and makes it possible for
+vertical movement to move through wrapped lines properly, instead of
+just treating them like non-wrapped lines.
+
+
The key event handlers now translate the key event into a string,
+something like Ctrl-Home or Shift-Cmd-R, and
+use that string to look up an action to perform. To make keybinding
+customizable, this lookup goes through
+a table, using a scheme that
+allows such tables to be chained together (for example, the default
+Mac bindings fall through to a table named 'emacsy', which defines
+basic Emacs-style bindings like Ctrl-F, and which is also
+used by the custom Emacs bindings).
+
+
A new
+option extraKeys
+allows ad-hoc keybindings to be defined in a much nicer way than what
+was possible with the
+old onKeyEvent
+callback. You simply provide an object mapping key identifiers to
+functions, instead of painstakingly looking at raw key events.
+
+
Built-in commands map to strings, rather than functions, for
+example "goLineUp" is the default action bound to the up
+arrow key. This allows new keymaps to refer to them without
+duplicating any code. New commands can be defined by assigning to
+the CodeMirror.commands object, which maps such commands
+to functions.
+
+
The hidden textarea now only holds the current selection, with no
+extra characters around it. This has a nice advantage: polling for
+input becomes much, much faster. If there's a big selection, this text
+does not have to be read from the textarea every time—when we poll,
+just noticing that something is still selected is enough to tell us
+that no new text was typed.
+
+
The reason that cheap polling is important is that many browsers do
+not fire useful events on IME (input method engine) input, which is
+the thing where people inputting a language like Japanese or Chinese
+use multiple keystrokes to create a character or sequence of
+characters. Most modern browsers fire input when the
+composing is finished, but many don't fire anything when the character
+is updated during composition. So we poll, whenever the
+editor is focused, to provide immediate updates of the display.
CodeMirror is a code-editor component that can be embedded in
+ Web pages. The 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 add-ons included in the distribution,
+ and
+ the CodeMirror
+ UI project, for reusable implementations of extra features.
+
+
CodeMirror works with language-specific modes. Modes are
+ JavaScript programs that help color (and optionally indent) text
+ written in a given language. The distribution comes with a 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:
Having done this, an editor instance can be created like
+ this:
+
+
var myCodeMirror = CodeMirror(document.body);
+
+
The editor will be appended to the document body, will start
+ empty, and will use the mode that we loaded. To have more control
+ over the new editor, a configuration object can be passed
+ to CodeMirror as a second argument:
This will initialize the editor with a piece of code already in
+ it, and explicitly tell it to use the JavaScript mode (which is
+ useful when multiple modes are loaded).
+ See below for a full discussion of the
+ configuration options that CodeMirror accepts.
+
+
In cases where you don't want to append the editor to an
+ element, and need more control over the way it is inserted, the
+ first argument to the CodeMirror function can also
+ be a function that, when given a DOM element, inserts it into the
+ document somewhere. This could be used to, for example, replace a
+ textarea with a real editor:
However, for this use case, which is a common way to use
+ CodeMirror, the library provides a much more powerful
+ shortcut:
+
+
var myCodeMirror = CodeMirror.fromTextArea(myTextArea);
+
+
This will, among other things, ensure that the textarea's value
+ is updated 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 or Doc)
+
The starting value of the editor. Can be a string, or
+ a document object.
+
+
mode (string or object)
+
The mode to use. When not given, this will default to the
+ first mode that was loaded. It may be a string, which either
+ simply names the mode or is
+ a MIME type
+ associated with the mode. Alternatively, it may be an object
+ containing configuration options for the mode, with
+ a name property that names the mode (for
+ example {name: "javascript", json: true}). The demo
+ pages for each mode contain information about what configuration
+ parameters the mode supports. You can ask CodeMirror which modes
+ and MIME types 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)
+
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)
+
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).
+
+
readOnly (boolean)
+
This disables editing of the editor content by the user. If
+ the special value "nocursor" is given (instead of
+ simply true), focusing of the editor is also
+ disallowed.
+
+
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.
+
+
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)
+
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)
+
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.
+
+
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.
+
+
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.
+
+
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
+
+
A CodeMirror instance emits a number of events, which allow
+ client code to react to various situations. These are registered
+ with the on method (and
+ removed with the off
+ method). These are the events that fire on the instance object.
+ The name of the event is followed by the arguments that will be
+ passed to the handler. The instance argument always
+ refers to the editor instance.
+
+
+
"change" (instance, changeObj)
+
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, change)
+
This event is fired before a change is applied, and its
+ handler may choose to modify or cancel the change.
+ The change 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 update(from, to, text)
+ and cancel() methods, which may be used to modify
+ or cancel the 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)
+
Will be fired when the cursor or selection moves, or any
+ change is made to the editor content.
+
+
"beforeSelectionChange" (instance, selection)
+
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, from, to)
+
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.
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", "blur" (instance)
+
These fire whenever the editor is focused or unfocused.
+
+
"scroll" (instance)
+
Fires when the editor is scrolled.
+
+
"update" (instance)
+
Will be fired whenever CodeMirror updates its DOM display.
+
+
"renderLine" (instance, line, 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.
+
+
+
It is also possible to register events on
+ other objects. Use CodeMirror.on(handle, "eventName",
+ func) to register handlers on objects that don't have their
+ own on method. Document objects (instances
+ of CodeMirror.Doc) emit the
+ following events:
+
+
+
"change" (doc, changeObj)
+
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).
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, changeObj)
+
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, 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" ()
+
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.
+
"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, 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.
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, and the default effect of
+ inserting a character will not occur).
+
+
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.
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 add-ons) 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.
+
+
Content manipulation methods
+
+
+
doc.getValue() → 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(string)
+
Set the editor content.
+
+
doc.getRange(from, to) → 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(string, from, to)
+
Replace the part of the document between from
+ and to with the given string. from
+ and to must be {line, ch}
+ objects. to can be left off to simply insert the
+ string at position from.
+
+
doc.getLine(n) → string
+
Get the content of line n.
+
doc.setLine(n, text)
+
Set the content of line n.
+
doc.removeLine(n)
+
Remove the given line from the document.
+
+
doc.lineCount() → number
+
Get the number of lines in the editor.
+
doc.firstLine() → number
+
doc.lastLine() → number
+
Get the first and last lines of the editor. This will
+ usually be zero and doc.lineCount() - 1 respectively,
+ but for linked sub-views,
+ or documents instantiated with a non-zero
+ first line, it might return other values.
+
+
doc.getLineHandle(num) → lineHandle
+
Fetches the line handle for the given line number.
+
doc.getLineNumber(handle) → 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) | doc.eachLine(start, end, f)
+
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.
+
doc.isClean() → boolean
+
Returns whether the document is currently clean (not
+ modified since initialization or the last call
+ to markClean).
+
+
+
Cursor and selection methods
+
+
+
doc.getSelection() → string
+
Get the currently selected code.
+
doc.replaceSelection(string)
+
Replace the selection with the given string.
+
+
doc.getCursor(start) → object
+
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)
+
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, head)
+
Set the selection range. anchor
+ and head should be {line, ch}
+ objects. head defaults to anchor when
+ not given.
+
doc.extendSelection(pos, pos2)
+
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(bool)
+
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() → bool
+
Tells you whether the editor currently has focus.
+
+
cm.findPosH(start, amount, unit, visually) → object
+
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, amount, unit) → object
+
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, value)
+
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) → value
+
Retrieves the current value of the given option for this
+ editor instance.
+
+
cm.addKeyMap(map, bottom)
+
Attach an additional keymap to the
+ editor. This is mostly useful for add-ons 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)
+
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, options)
+
Enable a highlighting overlay. This is a stateless mini-mode
+ that can be used to add extra highlighting. For example,
+ the search add-on 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)
+
Pass this the exact argument passed for
+ the mode parameter
+ to addOverlay to remove
+ an overlay again.
+
+
cm.on(type, func)
+
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, func)
+
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() → editor
+
Retrieve the editor associated with a document. May
+ return null.
+
+
cm.swapDoc(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) → 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) → 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, 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 (mode spec)
+
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)
+
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)
+
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() → object
+
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(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, to, options) → object
+
Can be used to mark a range of text with a specific CSS
+ class name. from and to should
+ be {line, ch} objects. The 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. A
+ the "clear" event
+ fired on the range handle can be used to be notified when this
+ happens.
+
replacedWith (dom node)
+
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).
+
readOnly
+
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).
+
startStyle
Can be used to specify
+ an extra CSS class to be applied to the leftmost span that
+ is part of the marker.
+
endStyle
Equivalent
+ to startStyle, but for the rightmost span.
+
shared
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 getOptions(copyWidget), which returns an
+ object representing the options for the marker.
+ If copyWidget is given an true, it will clone the
+ value of
+ the replacedWith
+ option, if any.
+
+
doc.setBookmark(pos, options) → object
+
Inserts a bookmark, a handle that follows the text around it
+ as it is being edited, at the given position. A bookmark has two
+ methods find() and clear(). The first
+ returns the current position of the bookmark, if it is still in
+ the document, and the second explicitly removes the bookmark.
+ The options argument is optional. If given, the following
+ properties are recognized:
+
+
widget
Can be used to display a DOM
+ node at the current location of the bookmark (analogous to
+ the replacedWith
+ option to markText).
+
insertLeft
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) → array
+
Returns an array of all the bookmarks and marked ranges
+ present at the given position.
+
doc.getAllMarks() → array
+
Returns an array containing all marked ranges in the document.
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)
+
Remove all gutter markers in
+ the gutter with the given ID.
+
+
cm.addLineClass(line, where, class) → 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.
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) → 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, node, scrollIntoView)
+
Puts node, which should be an absolutely
+ positioned DOM node, into the editor, positioned right below the
+ given {line, ch} position.
+ When scrollIntoView is true, the editor will ensure
+ that the entire node is visible (if possible). To remove the
+ widget again, simply use DOM methods (move it somewhere else, or
+ call removeChild on its parent).
+
+
cm.addLineWidget(line, node, options) → object
+
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.
+
+ 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, height)
+
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, y)
+
Scroll the editor to a given (pixel) position. Both
+ arguments may be left as null
+ or undefined to have no effect.
+
cm.getScrollInfo()
+
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, margin)
+
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, mode) → object
+
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, mode) → object
+
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, mode) → pos
+
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.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() → object
+
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 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.
+
+
cm.getTokenAt(pos) → 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.
+
+
+
cm.getStateAfter(line) → state
+
Returns the mode's parser state, if any, at the end of the
+ given line number. If no line number is given, the state at the
+ end of the document is returned. This can be useful for storing
+ parsing errors in the state, or getting other kinds of
+ contextual information for a line.
+
+
+
Miscellaneous methods
+
+
+
cm.operation(func) → result
+
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, dir)
+
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.
+
+
+
doc.posFromIndex(index) → object
+
Calculates and returns a {line, ch} object for a
+ zero-based index who's value is relative to the start of the
+ editor's text. If the index is out of range of the text then
+ the returned object is clipped to start or end of the text
+ respectively.
Returns the DOM node that represents the editor, and
+ controls its size. Remove this from your tree to delete an
+ editor instance.
+
cm.getScrollerElement() → node
+
Returns the DOM node that is responsible for the scrolling
+ of the editor.
+
cm.getGutterElement() → node
+
Fetches the DOM node that contains the editor gutters.
+
+
+
Static properties
+
+
The CodeMirror object itself provides
+ several useful properties. Firstly, its version
+ property contains a string that indicates the version of the
+ library. For releases, this simply
+ contains "major.minor" (for
+ example "2.33". For beta versions, " B"
+ (space, capital B) is added at the end of the string, for
+ development snapshots, " +" (space, plus) is
+ added.
+
+
The CodeMirror.fromTextArea
+ 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() → textarea
+
Returns the textarea that the instance was based on.
+
+
+
If you want to define extra methods in terms
+ of the CodeMirror API, it is possible to
+ use CodeMirror.defineExtension(name, value). This
+ will cause the given value (usually a method) to be added to all
+ CodeMirror instances created from then on.
+
+
Similarly, CodeMirror.defineOption(name,
+ default, updateFunc) 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.
+
+
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.
+
+
Add-ons
+
+
The addon directory in the distribution contains a
+ number of reusable components that implement extra editor
+ functionality. In brief, they are:
Provides a very simple way to query users for text input.
+ Adds an openDialog method to CodeMirror instances,
+ which can be called with an HTML fragment that provides the
+ prompt (should include an input tag), and a
+ callback function that is called when text has been entered.
+ Depends on addon/dialog/dialog.css.
Adds the getSearchCursor(query, start, caseFold) →
+ cursor method to CodeMirror instances, which can be used
+ to implement search/replace functionality. query
+ can be a regular expression or a string (only strings will match
+ across lines—if they contain newlines). start
+ provides the starting position of the search. It can be
+ a {line, ch} object, or can be left off to default
+ to the start of the document. caseFold is only
+ relevant when matching a string. It will cause the search to be
+ case-insensitive. A search cursor has the following methods:
+
+
findNext(), findPrevious() → boolean
+
Search forward or backward from the current position.
+ The return value indicates whether a match was found. If
+ matching a regular expression, the return value will be the
+ array returned by the match method, in case you
+ want to extract matched groups.
+
from(), to() → object
+
These are only valid when the last call
+ to findNext or findPrevious did
+ not return false. They will return {line, ch}
+ objects pointing at the start and end of the match.
+
replace(text)
+
Replaces the currently found match with the given text
+ and adjusts the cursor position to reflect the
+ replacement.
Implements the search commands. CodeMirror has keys bound to
+ these by default, but will not do anything with them unless an
+ implementation is provided. Depends
+ on searchcursor.js, and will make use
+ of openDialog when
+ available to make prompting for search queries less ugly.
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.
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)
+ to customize it. Demo
+ here.
Helps with code folding.
+ See the demo for an example.
+ Call CodeMirror.newFoldFunction with a range-finder
+ helper function to create a function that will, when applied to
+ a CodeMirror instance and a line number, attempt to fold or
+ unfold the block starting at the given line. A range-finder is a
+ language-specific function that also takes an instance and a
+ line number, and returns an range to be folded, or null if no
+ block is started on that line. There are files in
+ the addon/fold/
+ directory providing CodeMirror.braceRangeFinder,
+ which finds blocks in brace languages (JavaScript, C, Java,
+ etc), CodeMirror.indentRangeFinder, for languages
+ where indentation determines block structure (Python, Haskell),
+ and CodeMirror.tagRangeFinder, for XML-style
+ languages.
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 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 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]}
+ 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. The outer mode will not
+ see the content between the delimiters.
+ See this demo for an
+ example.
Provides a framework for showing autocompletion hints.
+ Defines CodeMirror.showHint, which takes a
+ CodeMirror instance and a hinting function, and pops up a widget
+ that allows the user to select a completion. Hinting functions
+ are function that take an editor instance, and return
+ a {list, from, to} object, where list
+ is an array of strings (the completions), and from
+ and to give the start and end of the token that is
+ being completed. Depends
+ on addon/hint/show-hint.css. See the other files in
+ the addon/hint for
+ hint sources for various languages. Check
+ out the demo for an
+ example.
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 lintWith option
+ that can be set to a warning source (for
+ example CodeMirror.javascriptValidator). Depends
+ on addon/lint/lint.css. A demo can be
+ found here.
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.
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.
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.
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..
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.
+
+
+
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() → character
+
Returns the next character in the stream without advancing
+ it. Will return an null at the end of the
+ line.
+
next() → character
+
Returns the next character in the stream and advances it.
+ Also returns null when no more characters are
+ available.
+
+
eat(match) → character
+
match can be a character, a regular expression,
+ or a function that takes a character and returns a boolean. If
+ the next character in the stream 'matches' the given argument,
+ it is consumed and returned. Otherwise, undefined
+ is returned.
+
eatWhile(match) → boolean
+
Repeatedly calls eat with the given argument,
+ until it fails. Returns true if any characters were eaten.
+
eatSpace() → boolean
+
Shortcut for eatWhile when matching
+ white-space.
+
skipToEnd()
+
Moves the position to the end of the line.
+
skipTo(ch) → boolean
+
Skips to the next occurrence of the given character, if
+ found on the current line (doesn't advance the stream if the
+ character does not occur on the line). Returns true if the
+ character was found.
+
match(pattern, consume, caseFold) → boolean
+
Act like a
+ multi-character eat—if consume is true
+ or not given—or a look-ahead that doesn't update the stream
+ position—if it is false. pattern can be either a
+ string or a regular expression starting with ^.
+ When it is a string, caseFold can be set to true to
+ make the match case-insensitive. When successfully matching a
+ regular expression, the returned value will be the array
+ returned by match, in case you need to extract
+ matched groups.
+
+
backUp(n)
+
Backs up the stream n characters. Backing it up
+ further than the start of the current token will cause things to
+ break, so be careful.
+
column() → integer
+
Returns the column (taking into account tabs) at which the
+ current token starts.
+
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.
+
+
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.
CodeMirror 2 is a complete rewrite that's
+ faster, smaller, simpler to use, and less dependent on browser
+ quirks. See this
+ and this
+ for more information.
More consistent page-up/page-down behaviour
+ across browsers. Fix some issues with hidden editors looping forever
+ when line-numbers were enabled. Make PHP parser parse
+ "\\" correctly. Have jumpToLine work on
+ line handles, and add cursorLine function to fetch the
+ line handle where the cursor currently is. Add new
+ setStylesheet function to switch style-sheets in a
+ running editor.
Adds removeLine method to API.
+ Introduces the PLSQL parser.
+ Marks XML errors by adding (rather than replacing) a CSS class, so
+ that they can be disabled by modifying their style. Fixes several
+ selection bugs, and a number of small glitches.
Add support for having both line-wrapping and
+ line-numbers turned on, make paren-highlighting style customisable
+ (markParen and unmarkParen config
+ options), work around a selection bug that Opera
+ reintroduced in version 10.
Solves some issues introduced by the
+ paste-handling changes from the previous release. Adds
+ setSpellcheck, setTextWrapping,
+ setIndentUnit, setUndoDepth,
+ setTabMode, and setLineNumbers to
+ customise a running editor. Introduces an SQL parser. Fixes a few small
+ problems in the Python
+ parser. And, as usual, add workarounds for various newly discovered
+ browser incompatibilities.
Overhaul of paste-handling (less fragile), fixes for several
+serious IE8 issues (cursor jumping, end-of-document bugs) and a number
+of small problems.
Introduces Python
+and Lua parsers. Add
+setParser (on-the-fly mode changing) and
+clearHistory methods. Make parsing passes time-based
+instead of lines-based (see the passTime option).
So you found a problem in CodeMirror. By all means, report it! Bug
+reports from users are the main drive behind improvements to
+CodeMirror. But first, please read over these points:
+
+
+
CodeMirror is maintained by volunteers. They don't owe you
+ anything, so be polite. Reports with an indignant or belligerent
+ tone tend to be moved to the bottom of the pile.
+
+
Include information about the browser in which the
+ problem occurred. Even if you tested several browsers, and
+ the problem occurred in all of them, mention this fact in the bug
+ report. Also include browser version numbers and the operating
+ system that you're on.
+
+
Mention which release of CodeMirror you're using. Preferably,
+ try also with the current development snapshot, to ensure the
+ problem has not already been fixed.
+
+
Mention very precisely what went wrong. "X is broken" is not a
+ good bug report. What did you expect to happen? What happened
+ instead? Describe the exact steps a maintainer has to take to make
+ the problem occur. We can not fix something that we can not
+ observe.
+
+
If the problem can not be reproduced in any of the demos
+ included in the CodeMirror distribution, please provide an HTML
+ document that demonstrates the problem. The best way to do this is
+ to go to jsbin.com, enter
+ it there, press save, and include the resulting link in your bug
+ report.
There are a few things in the 2.2 release that require some care
+when upgrading.
+
+
No more default.css
+
+
The default theme is now included
+in codemirror.css, so
+you do not have to included it separately anymore. (It was tiny, so
+even if you're not using it, the extra data overhead is negligible.)
+
+
Different key customization
+
+
CodeMirror has moved to a system
+where keymaps are used to
+bind behavior to keys. This means custom
+bindings are now possible.
+
+
Three options that influenced key
+behavior, tabMode, enterMode,
+and smartHome, are no longer supported. Instead, you can
+provide custom bindings to influence the way these keys act. This is
+done through the
+new extraKeys
+option, which can hold an object mapping key names to functionality. A
+simple example would be:
Keys can be mapped either to functions, which will be given the
+editor instance as argument, or to strings, which are mapped through
+functions through the CodeMirror.commands table, which
+contains all the built-in editing commands, and can be inspected and
+extended by external code.
+
+
By default, the Home key is bound to
+the "goLineStartSmart" command, which moves the cursor to
+the first non-whitespace character on the line. You can set do this to
+make it always go to the very start instead:
+
+
extraKeys: {"Home": "goLineStart"}
+
+
Similarly, Enter is bound
+to "newlineAndIndent" by default. You can bind it to
+something else to get different behavior. To disable special handling
+completely and only get a newline character inserted, you can bind it
+to false:
+
+
extraKeys: {"Enter": false}
+
+
The same works for Tab. If you don't want CodeMirror
+to handle it, bind it to false. The default behaviour is
+to indent the current line more ("indentMore" command),
+and indent it less when shift is held ("indentLess").
+There are also "indentAuto" (smart indent)
+and "insertTab" commands provided for alternate
+behaviors. Or you can write your own handler function to do something
+different altogether.
+
+
Tabs
+
+
Handling of tabs changed completely. The display width of tabs can
+now be set with the tabSize option, and tabs can
+be styled by setting CSS rules
+for the cm-tab class.
+
+
The default width for tabs is now 4, as opposed to the 8 that is
+hard-wired into browsers. If you are relying on 8-space tabs, make
+sure you explicitly set tabSize: 8 in your options.
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.)
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.
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.
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.
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.
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.
+
+
Documentation
+
+
The manual is your first stop for
+ learning how to use this library. It starts with a quick explanation
+ of how to use the editor, and then describes the API in detail.
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.
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 in standards mode
+ (Not quirks mode. But quasi-standards mode with a
+ transitional doctype is also flaky. <!doctype
+ html> is recommended.)
+
Internet Explorer 7 (standards mode) is usable, but buggy. It
+ has a z-index
+ bug that prevents CodeMirror from working properly.
+
+
+
I am not actively testing against every new browser release, and
+ vendors have a habit of introducing bugs all the time, so I am
+ relying on the community to tell me when something breaks.
+ See here for information on how to contact
+ me.
+
+
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.

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

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