Press ctrl-space to activate autocompletion. The
+completion uses
+the anyword-hint.js
+module, which simply looks at nearby words in the buffer and completes
+to those.
Demonstration of
+ using linked documents
+ to provide a split view on a document, and
+ using swapDoc
+ to use a single editor to display multiple documents.
On changes to the content of the above editor, a (crude) script
+tries to auto-detect the language used, and switches the editor to
+either JavaScript or Scheme mode based on that.
The emacs keybindings are enabled by
+including keymap/emacs.js and setting
+the keyMap option to "emacs". Because
+CodeMirror's internal API is quite different from Emacs, they are only
+a loose approximation of actual emacs bindings, though.
+
+
Also note that a lot of browsers disallow certain keys from being
+captured. For example, Chrome blocks both Ctrl-W and Ctrl-N, with the
+result that idiomatic use of Emacs keys will constantly close your tab
+or open a new window.
Demonstration of
+ the fullscreen
+ addon. Press F11 when cursor is in the editor to
+ toggle full screen editing. Esc can also be used
+ to exit full screen editing.
Demonstration of
+the hardwrap addon.
+The above editor has its change event hooked up to
+the wrapParagraphsInRange method, so that the paragraphs
+are reflown as you are typing.
The merge
+addon provides an interface for displaying and merging diffs,
+either two-way
+or three-way. The left
+(or center) pane is editable, and the differences with the other
+pane(s) are optionally shown live as you edit it.
Demonstration of a multiplexing mode, which, at certain
+ boundary strings, switches to one or more inner modes. The out
+ (HTML) mode does not get fed the content of the <<
+ >> blocks. See
+ the manual and
+ the source for more
+ information.
Demonstration of a mode that parses HTML, highlighting
+ the Mustache templating
+ directives inside of it by using the code
+ in overlay.js. View
+ source to see the 15 lines of code needed to accomplish this.
The placeholder
+ plug-in adds an option placeholder that can be set to
+ make text appear in the editor when it is empty and not focused.
+ If the source textarea has a placeholder attribute,
+ it will automatically be inherited.
This demo does the same thing as
+ the HTML5 completion demo, but
+ loads its dependencies
+ with Require.js, rather than
+ explicitly. Press ctrl-space to activate
+ completion.
By setting a few CSS properties, and giving
+the viewportMargin
+a value of Infinity, CodeMirror can be made to
+automatically resize to fit its content.
If this is a function, it will be called for each token with
+ two arguments, the token's text and the token's style class (may
+ be null for unstyled tokens). If it is a DOM node,
+ the tokens will be converted to span elements as in
+ an editor, and inserted into the node
+ (through innerHTML).
The mode/simple
+addon allows CodeMirror modes to be specified using a relatively simple
+declarative format. This format is not as powerful as writing code
+directly against the mode
+interface, but is a lot easier to get started with, and
+sufficiently expressive for many simple language modes.
+
+
This interface is still in flux. It is unlikely to be scrapped or
+overhauled completely, so do start writing code against it, but
+details might change as it stabilizes, and you might have to tweak
+your code when upgrading.
+
+
Simple modes (loosely based on
+the Common
+JavaScript Syntax Highlighting Specification, which never took
+off), are state machines, where each state has a number of rules that
+match tokens. A rule describes a type of token that may occur in the
+current state, and possibly a transition to another state caused by
+that token.
+
+
The CodeMirror.defineSimpleMode(name, states) method
+takes a mode name and an object that describes the mode's states. The
+editor below shows an example of such a mode (and is itself
+highlighted by the mode shown in it).
+
+
+
+
Each state is an array of rules. A rule may have the following properties:
+
+
+
regex: string | RegExp
+
The regular expression that matches the token. May be a string
+ or a regex object. When a regex, the ignoreCase flag
+ will be taken into account when matching the token. This regex
+ should only capture groups when the token property is
+ an array.
+
token: string | null
+
An optional token style. Multiple styles can be specified by
+ separating them with dots or spaces. When the regex for
+ this rule captures groups, it must capture all of the
+ string (since JS provides no way to find out where a group matched),
+ and this property must hold an array of token styles that has one
+ style for each matched group.
+
next: string
+
When a next property is present, the mode will
+ transfer to the state named by the property when the token is
+ encountered.
+
push: string
+
Like next, but instead replacing the current state
+ by the new state, the current state is kept on a stack, and can be
+ returned to with the pop directive.
+
pop: bool
+
When true, and there is another state on the state stack, will
+ cause the mode to pop that state off the stack and transition to
+ it.
+
mode: {spec, end, persistent}
+
Can be used to embed another mode inside a mode. When present,
+ must hold an object with a spec property that describes
+ the embedded mode, and an optional end end property
+ that specifies the regexp that will end the extent of the mode. When
+ a persistent property is set (and true), the nested
+ mode's state will be preserved between occurrences of the mode.
+
indent: bool
+
When true, this token changes the indentation to be one unit
+ more than the current line's indentation.
+
dedent: bool
+
When true, this token will pop one scope off the indentation
+ stack.
+
dedentIfLineStart: bool
+
If a token has its dedent property set, it will, by
+ default, cause lines where it appears at the start to be dedented.
+ Set this property to false to prevent that behavior.
+
+
+
The meta property of the states object is special, and
+will not be interpreted as a state. Instead, properties set on it will
+be set on the mode, which is useful for properties
+like lineComment,
+which sets the comment style for a mode. The simple mode addon also
+recognizes a few such properties:
+
+
+
dontIndentStates: array<string>
+
An array of states in which the mode's auto-indentation should
+ not take effect. Usually used for multi-line comment and string
+ states.

+CodeMirror: Automatically derive odd wrapping behavior for your browser
+
+
+
+
Automatically derive odd wrapping behavior for your browser
+
+
+
This is a hack to automatically derive
+ a spanAffectsWrapping regexp for a browser. See the
+ comments above that variable
+ in lib/codemirror.js
+ for some more details.
The vim keybindings are enabled by
+including keymap/vim.js and setting
+the vimMode option to true. This will also
+automatically change the keyMap option to "vim".
+
+
Features
+
+
+
All common motions and operators, including text objects
+
Operator motion orthogonality
+
Visual mode - characterwise, linewise, partial support for blockwise
Note that while the vim mode tries to emulate the most useful features of
+vim as faithfully as possible, it does not strive to become a complete vim
+implementation
This demo runs JSHint over the code
+in the editor (which is the script used on this page), and
+inserts line widgets to
+display the warnings that JSHint comes up with.
Press ctrl-space, or type a '<' character to
+ activate autocompletion. This demo defines a simple schema that
+ guides completion. The schema can be customized—see
+ the manual.

CodeMirror is a versatile text editor
+ implemented in JavaScript for the browser. It is specialized for
+ editing code, and comes with a number of language modes and addons
+ that implement more advanced editing functionality.
+
+
A rich programming API and a
+ CSS theming system are
+ available for customizing CodeMirror to fit your application, and
+ extending it with new functionality.
Development and bug tracking happens
+ on github
+ (alternate git
+ repository).
+ Please read these
+ pointers before submitting a bug. Use pull requests to submit
+ patches. All contributions must be released under the same MIT
+ license that CodeMirror uses.
+
+
Discussion around the project is done on
+ a mailing list.
+ There is also
+ the codemirror-announce
+ list, which is only used for major announcements (such as new
+ versions). If needed, you can
+ contact the maintainer
+ directly.
+
+
A list of CodeMirror-related software that is not part of the
+ main distribution is maintained
+ on our
+ wiki. Feel free to add your project.
+
+
+
+
Browser support
+
The desktop versions of the following browsers,
+ in standards mode (HTML5 <!doctype html>
+ recommended) are supported:
+
+
Firefox
version 4 and up
+
Chrome
any version
+
Safari
version 5.2 and up
+
Internet Explorer
version 8 and up
+
Opera
version 9 and up
+
+
Modern mobile browsers tend to partly work. Bug reports and
+ patches for mobile support are welcome, but the maintainer does not
+ have the time or budget to actually work on it himself.

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

Mode for html embedded scripts like JSP and ASP.NET. Depends on HtmlMixed which in turn depends on

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

+ 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.

+CodeMirror: HTTP mode
+
+
+
+
+
+
+
+
This is a list of every mode in the distribution. Each mode lives
+in a subdirectory of the mode/ directory, and typically
+defines a single JavaScript file that implements the mode. Loading
+such file will make the language available to CodeMirror, through
+the mode
+option.
+ JavaScript mode supports several configuration options:
+
+
json which will set the mode to expect JSON
+ data rather than a JavaScript program.
+
jsonld which will set the mode to expect
+ JSON-LD linked data rather
+ than a JavaScript program (demo).
+
typescript which will activate additional
+ syntax highlighting and some other things for TypeScript code
+ (demo).
+
statementIndent which (given a number) will
+ determine the amount of indentation to use for statements
+ continued on a new line.
+
wordCharacters, a regexp that indicates which
+ characters should be considered part of an identifier.
+ Defaults to /[\w$]/, which does not handle
+ non-ASCII identifiers. Can be set to something more elaborate

+ array of strings to have those identifiers highlighted with
+ the lua-special style.

MIME types defined:text/x-lua.
