Add CKEditor Wysiwyg features in Trac wiki


This is a Wysiwyg wiki editor plugin using the open-source CKEditor, inspired by TracWysiwygPlugin.

Note: The full_integration mode is not recommended for use in production! It is still experimental, and under development.

The plugin does not contain the CKEditor source. Get it from their SVN - require >= 3.6. After installation of both the plugin and CKEditor, set the [ckeditor] editor_source option for this plugin to the path of the CKEditor ckeditor.js script.

The plugin has several modes of integration, determined by the [ckeditor] editor_type option:

html_wrapper CKEditor with HTML output wrapped in html-processor
full_integration CKEditor with TracWiki output (experimental)
only_ticket CKEditor with TracWiki output for ticket fields (experimental); leaves wiki editing as in Trac standard
only_wiki CKEditor with TracWiki output for wiki pages (experimental); leaves ticket editing as in Trac standard
none No integration - plain old textarea

Using CKEditorPlugin looks like this in Trac:

The full_integration mode is the holy grail, but currently just a handful of elements are supported in this mode, see the tracwiki plugin for details.


  • Does not co-exist with TracWysiwygPlugin: ensure that only one of them is enabled if both plugins are present in your environment.
  • When using the html_wrapper mode and editing an existing wiki page, the page will be rendered in HTML upon save (macros are lost, etc.)

Download the zipped source from here.


You can check out CkEditorPlugin from here using Subversion, or browse the source with Trac.


Install the plugin:


Get the CKEditor package and deploy it in a URL-accessible path, e.g. the htdocs directory of your Trac environment:

mkdir /path/to/trac/environment/htdocs/js
svn checkout /path/to/trac-env/htdocs/js/ckeditor

Enable it from the Plugins section of the Administration panel, or by adding the following to the [components] section of your trac.ini file:

ckintegration.* = enabled


The following options can be specified in the [ckeditor] section of your trac.ini file:

code_styles List of code styles, which should be processed by CKEditor and displayed in CKEditor dialog 'insert code'. Possible types are one of pygments-styles.

default values: cpp, csharp, java, js, python, sql, default, xml

editor_type Type of integrated editor. Possible types are:

  • full_integration: CKEditor with TracWiki output (experimental),
  • only_ticket: CKEditor with TracWiki output for ticket fields (experimental); leaves wiki editing as in Trac standard,
  • only_wiki: CKEditor with TracWiki output for wiki pages (experimental); leaves ticket editing as in Trac standard,
  • html_wrapper: CKEditor with HTML output wrapped in html-processor,
  • none: No integration - leaves editing as in Trac standard

default value: full_integration

editor_source Path to CKEditor 3.6.x javascript source. The path should be specified as viewed by the client, and must be accessible by the client-browser. A recommended setup involves installing CKEditor in the htdocs/js directory of the Trac environment, and setting this option to site/js/ckeditor/ckeditor.js.

default value: site/js/ckeditor/ckeditor.js

You can also type [[TracIni(ckeditor)]] in any Wiki-Page to get a list of possible options and their descriptions. See also description in plugins-panel.

Sample configuration of a trac.ini file (default values shown):

code_styles = cpp, csharp, java, js, python, sql, default, xml
editor_type = full_integration
editor_source = site/js/ckeditor/ckeditor.js

Known Issues / Limitations

  • Marker and text color is not working in headers, see Google-Groups.
  • When inserting an image, only full path to image is working.
  • When entering a link manually, it is printed with an exclamation mark, see #9562.
  • Escaping of CamelCase words is only working the first time, see #9563.
  • Copying lists from MS Word does not maintain deeply nested indentations (tested with Word 2003).

To do

Help wanted for further development:

  • Killer feature: Support TracWiki syntax by HTML<->TracWiki conversions? or by making CKEditor's rendering engine emit TracWiki?.
  • Insert WikiLinks using cool dialogs, for example choose existing page from TitleIndex, insert link to stubbed page & open new tab to create the stubbed page.
  • Insert other kinds of TracLinks using cool dialogs, such as changesets, tickets, other resources.
  • Insert images intuitively: this requires a selector from attachments / repositories / upload from file-system as attachment or into repository, maybe even drag-and-drop.
  • Macro-awareness: select macro to insert from supported macros, expand inserted macros inline.
