  • Trac Syntax Coloring

    v1 v2  
    11= Syntax Coloring of Source Code =
    2 Trac supports language-specific colorization (syntax highlighting) of source code in [wiki:WikiFormatting WikiFormatted] text and the [wiki:TracBrowser Source Browser].
     2Trac supports language-specific syntax highlighting of source code in [wiki:WikiFormatting wiki formatted] text and the [wiki:TracBrowser repository browser].
    33
    4 To perform this, Trac relies on external software packages with support for a great number of programming languages.
     4To do this, Trac uses external libraries with support for a great number of programming languages.
    55
    6 Currently Trac supports syntax coloring using [http://people.ssh.fi/mtr/genscript/ GNU Enscript] and [http://silvercity.sourceforge.net/ SilverCity].
     6Currently Trac supports syntax coloring using one or more of the following packages:
    77
    8 '''To activate syntax coloring, simply install !SilverCity and/or Enscript.'''
     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])
    911
    10 Trac will automatically prioritize using !SilverCity before Enscript if possible. If neither is available, Trac will display the data as plain text.
     12To 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`.
    1113
    12 '''Note:''' ''Enscript supports a greater number of languages, however !SilverCity is generally faster since it is a library, not having to execute an external process.''
    13 [[br]]'''Note:''' ''Syntax Coloring is only available on trac >= 0.7.''
     14If 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
     15
     16When in use, Trac will automatically prioritize !SilverCity highlighting over Enscript if possible, (see note below).
     17
     18If 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.
     24
     25=== About Pygments ===
     26
     27Starting 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.
     28
     29To 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].
     30
     31It'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.
