    26Trac supports language-specific syntax highlighting of source code within wiki formatted text in [WikiProcessors#CodeHighlightingSupport wiki processors] blocks and in the [TracBrowser repository browser].

    … …  
    610Currently Trac supports syntax coloring using one or more of the following packages:
    711
    8  * [http://pygments.pocoo.org/ Pygments], by far the preferred system, as it covers a wide range of programming languages and other structured texts and is actively supported
    9  * [http://www.codento.com/people/mtr/genscript/ GNU Enscript], commonly available on Unix but somewhat unsupported on Windows
    10  * [http://silvercity.sourceforge.net/ SilverCity], legacy system, some versions can be [http://trac.edgewall.org/wiki/TracFaq#why-is-my-css-code-not-being-highlighted-even-though-i-have-silvercity-installed problematic]
     12 * '''[http://pygments.org/ Pygments]''', the preferred system, as it covers a wide range of programming languages and other structured texts and is actively supported.
     13 * [http://www.codento.com/people/mtr/genscript/ GNU Enscript], commonly available on Unix, and has an [http://gnuwin32.sourceforge.net/packages/enscript.htm unsupported version] on Windows; use is deprecated.
     14 * [http://silvercity.sourceforge.net/ SilverCity], legacy system, some versions can be problematic; use is deprecated.

     16To activate syntax coloring, simply install either one (or more) of these packages. If none of these packages is available, Trac will display the data as plain text.

     18== About Pygments
    1519
     20Pygments is a highlighting library implemented in pure Python, very fast, easy to extend and [http://pygments.org/docs/ well documented].

    17 === About Pygments ===
     22The Pygments default style can specified in the [TracIni#mimeviewer-section mime-viewer] section of your TracIni file. The default style can be overridden by setting a Style preference on the [/prefs/pygments preferences page].
    1823
    19 Starting with trac 0.11 [http://pygments.org/ pygments] will be the new default highlighter. It's a highlighting library implemented in pure python, very fast, easy to extend and [http://pygments.org/docs/ well documented].
     24The list below contains only the most commonly used processors and the [http://pygments.org/docs/lexers/ list of supported Pygments lexers] is growing weekly.
    2025
    21 The Pygments default style can specified in the [TracIni#mimeviewer-section mime-viewer] section of trac.ini. The default style can be overridden by setting a Style preference on the [/prefs/pygments preferences page].
    22 
    23 It's very likely that the list below is outdated because the list of supported pygments lexers is growing weekly. Just have a look at the page of [http://pygments.org/docs/lexers/ supported lexers] on the pygments webpage.

    2828=== Known MIME Types
    … …  
    3232Note that the 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.
    3333
    34 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.
     34Similarly, 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.
    3535
    36 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 `text/xml` mimetype.

    38 If mimetype such as 'svn:mime-type' is set to 'text/plain', there is no coloring even if file is known type like 'java'.
     38If a mimetype property such as `svn:mime-type` is set to `text/plain`, there is no coloring even if the file is of a known type, like `java`.
