Features

- +
+

Community

-
+

CodeMirror is an open-source project shared under + an MIT license. It is the editor used in the + dev tools for + both Firefox + and Chrome, Light + Table, Adobe + Brackets, Bitbucket, + and many other projects.

-

Usage demos:

+

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.

- - -

Real-world uses:

- - - -
- -

Getting the code

- -

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

- -

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

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

CodeMirror can also be found on GitHub at marijnh/CodeMirror. - If you plan to hack on the code and contribute patches, the best way - to do it is to create a GitHub fork, and send pull requests.

- -

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.

- -

For those who want to learn more about the code, there is - an overview of the internals available. - The source code - itself is, for the most part, also well commented.

- -

Support and bug reports

- -

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

- -

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

- -

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

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.

-

Supported browsers

+

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.

+ -

The following desktop browsers are able to run CodeMirror:

+
+

Browser support

+

The desktop versions of the following browsers, + in standards mode (HTML5 <!doctype html> + recommended) are supported:

+ + + + + + +
Firefoxversion 4 and up
Chromeany version
Safariversion 5.2 and up
Internet Explorerversion 8 and up
Operaversion 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.

+
-
    -
  • Firefox 2 or higher
    • -
  • Chrome, any version
    • -
  • Safari 3 or higher
    • -
  • Opera 9 or higher (with some key-handling problems on OS X)
    • -
  • Internet Explorer 7 or higher in standards mode
    - (So not quirks mode. But quasi-standards mode with a - transitional doctype is also flaky. <!doctype - html> is recommended.)
    • -
- -

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.
