For example, if your project is named 'sandbox', and the image file is 'red_logo.gif' then the 'src' setting would be 'site/red_logo.gif', not 'sandbox/red_logo.gif'.

    5866Trac is using [http://genshi.edgewall.org Genshi] as the templating engine. Documentation is yet to be written, in the meantime the following tip should work.
    5967
    6068Say you want to add a link to a custom stylesheet, and then your own
    61 header and footer.  Create a file {{{/path/to/env/templates/site.html}}} or {{{/path/to/inherit/option/templates_dir/site.html}}}, with contents like this:
     69header and footer. Save the following content as 'site.html' inside your projects templates directory (each Trac project can have their own site.html), e.g. {{{/path/to/env/templates/site.html}}}:
    6270
    6371{{{
    … …  
    6977  <!--! Add site-specific style sheet -->
    7078  <head py:match="head" py:attrs="select('@*')">
    71     ${select('*')}
     79    ${select('*|comment()|text()')}
    7280    <link rel="stylesheet" type="text/css"
    7381          href="${href.chrome('site/style.css')}" />
    … …  
    8997</html>
    9098}}}
    91 Note that this references your environment's `htdocs/style.css`.
     99
     100Those who are familiar with XSLT may notice that Genshi templates bear some similarities. However, there are some Trac specific features - for example '''${href.chrome('site/style.css')}''' attribute references template placed into environment's ''htdocs/''  In a similar fashion '''${chrome.htdocs_location}''' is used to specify common ''htdocs/'' directory from Trac installation.
     101
     102`site.html` is one file to contain all your modifications. It usually works by the py:match (element or attribute), and it allows you to modify the page as it renders - the matches hook onto specific sections depending on what it tries to find
     103and modify them.
     104See [http://groups.google.com/group/trac-users/browse_thread/thread/70487fb2c406c937/ this thread] for a detailed explanation of the above example `site.html`.
     105A site.html can contain any number of such py:match sections for whatever you need to modify. This is all [http://genshi.edgewall.org/ Genshi], so the docs on the exact syntax can be found there.

    105 If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can actually be loaded by using a workaroud - providing it contains no ClearSilver processing. In addition, as only one element can be imported, the content needs some sort of wrapper such as a `<div>` block or other similar parent container. The XInclude namespace must be specified to allow includes, but that can be moved to document root along with the others:
     120This example illustrates a technique of using '''`req.environ['PATH_INFO']`''' to limit scope of changes to one view only. For instance, to make changes in site.html only for timeline and avoid modifying other sections - use  ''`req.environ['PATH_INFO'] == '/timeline'`'' condition in <py:if> test.

    117138Also note that the `site.html` (despite its name) can be put in a common templates directory - see the `[inherit] templates_dir` option. This could provide easier maintainence (and a migration path from 0.10 for larger installations) as one new global `site.html` file can be made to include any existing header, footer and newticket snippets.

    122144The following is the basic template used by Trac to display a list of links to the projects.  For projects that could not be loaded it displays an error message. You can use this as a starting point for your own index template.

    150172Once you've created your custom template you will need to configure the webserver to tell Trac where the template is located (pls verify ... not yet changed to 0.11):

     208== Project Templates ==
     209
     210The appearance of each individual Trac environment (that is, instance of a project) can be customized independently of other projects, even those hosted by the same server. The recommended way is to use a `site.html` template (see [#SiteAppearance]) whenever possible. Using `site.html` means changes are made to the original templates as they are rendered, and you should not normally need to redo modifications whenever Trac is upgraded. If you do make a copy of `theme.html` or any other Trac template, you need to migrate your modifiations to the newer version - if not, new Trac features or bug fixes may not work as expected.
     211
     212With that word of caution, any Trac template may be copied and customized. The default Trac templates are located inside the installed Trac egg (`/usr/lib/pythonVERSION/site-packages/Trac-VERSION.egg/trac/templates, .../trac/ticket/templates, .../trac/wiki/templates, ++`). The [#ProjectList] template file is called `index.html`, while the template responsible for main layout is called `theme.html`. Page assets such as images and CSS style sheets are located in the egg's `trac/htdocs` directory.
     213
     214However, do not edit templates or site resources inside the Trac egg - installing Trac again can completely delete your modifications. Instead use one of two alternatives:
     215 * For a modification to one project only, copy the template to project `templates` directory.
     216 * For a modification shared by several projects, copy the template to a shared location and have each project point to this location using the `[inherit] templates_dir =` trac.ini option.
     217
     218Trac resolves requests for a template by first looking inside the project, then in any inherited templates location, and finally inside the Trac egg.
     219
     220Trac caches templates in memory by default to improve performance. To apply a template you need to restart the server.
