Syntax Coloring of Source Code
Trac supports language-specific syntax highlighting of source code within wiki formatted text in wiki processors blocks and in the repository browser. Syntax coloring is provided using Pygments, which covers a wide range of programming languages and other structured texts, and is actively supported. If Pygments is not available, Trac will display the content as plain text.
Syntax Coloring Support
The list of currently supported languages can be found on the supported languages page. The list represents the languages supported in the most recent version of Pygments, so the languages actually supported in your installation could differ if you have an older version installed. The listing of supported lexers provides additional information about the default mime type to keyword mappings.
Explicit control of the mime type associated with a WikiProcessor and file extension is available through the
mime_map setting. For example, by default
.m files are considered Objective-C files. In order to treat
.m files as MATLAB files, add
text/matlab:m to the
mime_map setting in the [mimeviewer] section of trac.ini.
If a mimetype property such as
svn:mime-type is set to
text/plain, there is no coloring even if file is known type like
Rich content may be directly rendered instead of syntax highlighted. This usually depends on which auxiliary packages are installed and on which components are activated in your setup. For example a
text/x-rst document will be rendered via
docutils if it is installed and the
trac.mimeview.rst.ReStructuredTextRenderer is not disabled, and will be syntax highlighted otherwise.
In a similar way, a document with the mimetype
text/x-trac-wiki is rendered using the Trac wiki formatter, unless the
trac.mimeview.api.WikiTextRenderer component is disabled.
HTML documents are directly rendered only if the
render_unsafe_html settings are enabled in the TracIni (those settings are present in multiple sections, as there are different security concerns depending where the document comes from). If you want to ensure that an HTML document gets syntax highlighted and not rendered, use the
Known MIME types
