v2 v3 1 1 = Customizing the Trac Interface = 2 2 [[TracGuideToc]] 3 [[PageOutline]] 3 4 4 5 == Introduction == 5 This page is meant to give users suggestions on how they can customize the look of Trac. Topics on this page cover editing the HTML templates and CSS files, but not the program code itself. The topics are intended to show users how they can modify the look of Trac to meet their specific needs.Suggestions for changes to Trac's interface applicable to all users should be filed as tickets, not listed on this page.6 This page gives suggestions on how to customize the look of Trac. Topics include editing the HTML templates and CSS files, but not the program code itself. The topics show users how they can modify the look of Trac to meet their specific needs. Suggestions for changes to Trac's interface applicable to all users should be filed as tickets, not listed on this page. 6 7 7 8 == Project Logo and Icon == 8 The easiest parts of the Trac interface to customize are the logo and the site icon. 9 10 The logo or icon image should be put in a folder named "htdocs" in your project's environment folder. (''Note: in projects created with a Trac version prior to 0.9 you will need to create this folder'')9 The easiest parts of the Trac interface to customize are the logo and the site icon. Both of these can be configured with settings in [wiki:TracIni trac.ini]. 10 11 The logo or icon image should be put in a folder named "htdocs" in your project's environment folder. ''Note: in projects created with a Trac version prior to 0.9 you will need to create this folder''. 11 12 12 13 ''Note: you can actually put the logo and icon anywhere on your server (as long as it's accessible through the web server), and use their absolute or server-relative URLs in the configuration.'' … … 15 16 16 17 === Logo === 17 Change the `src` setting to `site/` followed by the name of your image file. The `width` and `height` settings should be modified to match your image's dimensions (the Trac chrome handler uses "`site/`" for files within the project directory `htdocs` and "`common/`" for the common ones).18 Change the `src` setting to `site/` followed by the name of your image file. The `width` and `height` settings should be modified to match your image's dimensions. The Trac chrome handler uses "`site/`" for files within the project directory `htdocs`, and "`common/`" for the common `htdocs` directory belonging to a Trac installation. Note that 'site/' is not a placeholder for your project name, it is the literal prefix that should be used. 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'. 18 19 19 20 {{{ … … 26 27 27 28 === Icon === 28 Icons should be a 16x16 image in `.gif` or `.ico` format. Change the `icon` setting to `site/` followed by the name of your icon file. Icons will typically be displayed by your web browser next to the site's URL and in the `Bookmarks` menu.29 Icons are small images displayed by your web browser next to the site's URL and in the `Bookmarks` menu. Icons should be a 32x32 image in `.gif` or `.ico` format.

To make the project icon work in both IE and other browsers, you can store the icon in the document root of the host, and reference it from ``trac.ini`` as follows:36 Note that this icon is ignored by Internet Explorer, which only accepts a file named `favicon.ico` at the root of the host.

We also make the "View Tickets" entry link to a specific report .51 The new [mainnav] and [metanav] can now be used to customize the text and link used for the navigation items, or even to disable them, but not for adding new ones. 52 53 In the following example, we rename the link to the Wiki start "Home", and hide the "!Help/Guide".

Documentation is yet to be written, in the meantime the following tip should work. 60 61 Say you want to add a link to a custom stylesheet, and then your own 62 header 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}}}: 67 Trac is using [http://genshi.edgewall.org Genshi] as the templating engine.

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. 94 95 site.html is one file to contain all your modifications. It usually works by the py:match (element of 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 96 and modify them. A 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. 97 98 99 Example snippet of adding introduction text to the new ticket form (hide when preview): 100 101 {{{ 102 #!xml 97 Notice that XSLT bears some similarities with Genshi templates. However, there are some Trac specific features, for example the `${href.chrome('site/style.css')}` attribute references `style.css` in the environment's `htdocs/` directory. In a similar fashion `${chrome.htdocs_location}` is used to specify the common `htdocs/` directory belonging to a Trac installation. That latter location can however be overriden using the [[TracIni#trac-section|[trac] htdocs_location]] configuration setting. 98 99 `site.html` is one file to contain all your modifications.

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. 112 113 If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can actually be loaded by using a workaround - 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: 114 This example illustrates a technique of using `req.environ['PATH_INFO']` to limit scope of changes to one view only.

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.204 The appearance of each individual Trac environment, ie instance of a project, can be customized independently of other projects, even those hosted on the same server.

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. 195 207 196 However, do not edit templates or site resources inside the Trac egg - installing Trac again can completely delete your modifications. Instead use one of twoalternatives:208 However, do not edit templates or site resources inside the Trac egg. Reinstalling Trac overwrites your modifications. Instead use one of these alternatives: 197 209 * For a modification to one project only, copy the template to project `templates` directory. 198 210 * 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. … … 201 213 202 214 Trac caches templates in memory by default to improve performance. To apply a template you need to restart the server. 215 203 216 ---- 204 217 See also TracGuide, TracIni
