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 discussion forum.
- 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.

-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).
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.
