    11= Syntax Coloring of Source Code = 
    2 Trac supports language-specific syntax highlighting of source code in [wiki:WikiFormatting wiki formatted] text and the [wiki:TracBrowser repository browser]. 
     2Trac supports language-specific syntax highlighting of source code within wiki formatted text in [WikiProcessors#CodeHighlightingSupport wiki processors] blocks and in the [TracBrowser repository browser]. 
    33 
    44To do this, Trac uses external libraries with support for a great number of programming languages. 
     
    66Currently Trac supports syntax coloring using one or more of the following packages: 
    77 
    8  * [http://www.codento.com/people/mtr/genscript/ GNU Enscript]  
    9  * [http://silvercity.sourceforge.net/ SilverCity] 
    10  * [http://pygments.pocoo.org/ Pygments] (but needs a plugin for 0.10, see [#AboutPygments below]) 
     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] 
    1111 
    12 To activate syntax coloring, simply install either one (or more) of these packages. No additional configuration is required, however to modify the colors, have a look at `trac/htdocs/css/code.css`. 
    1312 
    14 If you don't know why trac isnt detecting an installed library, try turning on Trac logging. It actually appears that Trac is broken with SilverCity 0.9.6. Either use the current 0.9.7 or the older 0.9.5 http://trac.edgewall.org/wiki/TracFaq#why-is-my-css-code-not-being-highlighted-even-though-i-have-silvercity-installed 
     13To activate syntax coloring, simply install either one (or more) of these packages (see [#ExtraSoftware] section below). 
     14If none of these packages is available, Trac will display the data as plain text.  
    1515 
    16 When in use, Trac will automatically prioritize !SilverCity highlighting over Enscript if possible, (see note below).  
    17  
    18 If neither package is available, Trac will display the data as plain text.  
    19  
    20 '''Note:''' Enscript supports a greater number of languages, however !SilverCity is generally faster since it is a library and isn't executed in an external process. 
    21  
    22 === About SilverCity === 
    23 !SilverCity uses the lexer from [http://www.scintilla.org/ Scintilla]. Scintilla supports more languages than !SilverCity implements. If you want to add a language to !SilverCity supported by Scintilla, it's not very difficult. See [http://trac.edgewall.org/wiki/SilverCityAddLanguage SilverCityAddLanguage] for some information how. 
    2416 
    2517=== About Pygments === 
    2618 
    27 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]. While it does not support as many languages as Enscript or Scintilla the overall output quality is much better. 
     19Starting 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]. 
    2820 
    29 To use pygments trac 0.11 you just have to install pygments 0.5.1 or higher. If you want to use it in trac 0.10 too you have to install the [http://trac-hacks.org/wiki/TracPygmentsPlugin TracPygmentsPlugin] from trac hacks.  If you encounter any bugs, please file tickets regarding Pygments in [http://dev.pocoo.org/projects/pygments/ the pygments trac]. 
     21The 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].  
    3022 
    3123It'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.

     28=== Known MIME Types 
    8629 
    87 ''(*) Supported as inline code blocks in [wiki:WikiFormatting Wiki text] using WikiProcessors.'' 
     30[[KnownMimeTypes]] 
    8831 
    89 ''(1) Ruby highlighting is not included in the Enscript distribution. [http://www.nicetick.com ckan air jordan]. Highlighting rules for Ruby can be obtained from: http://neugierig.org/software/ruby/ 
     32Note 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. 
    9033 
    91 ''(2) C# highlighting is not included in the Enscript distribution.  Highlighting rules for C# can be obtained from: http://wiki.hasno.info/index.php/Csharp.st 
     34In 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. 
    9235 
    93 ''(3) Fortran: as packaged, Enscript only supports the fixed source form. Highlighting rules for Fortran 90x/2003 can be obtained from: http://wiki.hasno.info/index.php/F90.st 
     36HTML 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. 
    9437 
    95 ''(4) since Silvercity 0.9.7 released on 2006-11-23 
    9638 
    97 ''(5) By default `.m` files are considered Objective-C files. In order to treat `.m` files as MATLAB files, add "text/x-matlab:m" to the "mime_map" setting in the [wiki:TracIni#mimeviewer-section "[mimeviewer] section of trac.ini"].
