46 | | These files may contain static HTML, though if users desire to have dynamically generated content they can make use of the [http://www.clearsilver.net/ ClearSilver] templating language from within the pages as well. When you need to see what variables are available to the template, append the query string `?hdfdump=1` to the URL of your Trac site. This will display a structured view of the template data. |
47 | | |
48 | | == Site CSS == |
49 | | The primary means to adjust the layout of a Trac site is to add [http://www.w3.org/TR/REC-CSS2/ CSS] style rules that overlay the default rules. This is best done by editing the `site_css.cs` file in the enviroment's `templates` directory. The content of that template gets inserted into a `<style type="text/css"></style>` element on every HTML page generated by Trac. |
50 | | |
51 | | While you can add your custom style rules directly to the `site_css.cs` file, it is recommended that you simply reference an external style sheet, thereby enabling browsers to cache the CSS file instead of transmitting the rules with every response. |
52 | | |
53 | | The following example would import a style sheet located in the `style` root directory of your host: |
54 | | {{{ |
55 | | @import url(/style/mytrac.css); |
| 51 | [metanav] |
| 52 | help = disabled |
60 | | @import url(<?cs var:chrome.href ?>/site/style.css); |
| 65 | #!xml |
| 66 | <html xmlns="http://www.w3.org/1999/xhtml" |
| 67 | xmlns:py="http://genshi.edgewall.org/" |
| 68 | py:strip=""> |
| 69 | |
| 70 | <!--! Add site-specific style sheet --> |
| 71 | <head py:match="head" py:attrs="select('@*')"> |
| 72 | ${select('*|comment()|text()')} |
| 73 | <link rel="stylesheet" type="text/css" |
| 74 | href="${href.chrome('site/style.css')}" /> |
| 75 | </head> |
| 76 | |
| 77 | <body py:match="body" py:attrs="select('@*')"> |
| 78 | <!--! Add site-specific header --> |
| 79 | <div id="siteheader"> |
| 80 | <!--! Place your header content here... --> |
| 81 | </div> |
| 82 | |
| 83 | ${select('*|text()')} |
| 84 | |
| 85 | <!--! Add site-specific footer --> |
| 86 | <div id="sitefooter"> |
| 87 | <!--! Place your footer content here... --> |
| 88 | </div> |
| 89 | </body> |
| 90 | </html> |
| 91 | }}} |
| 92 | Note that this references your environment's `htdocs/style.css`. |
| 93 | |
| 94 | Example snippet of adding introduction text to the new ticket form (hide when preview): |
| 95 | |
| 96 | {{{ |
| 97 | #!xml |
| 98 | <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')"> |
| 99 | <py:if test="req.environ['PATH_INFO'] == '/newticket' and (not 'preview' in req.args)"> |
| 100 | <p>Please make sure to search for existing tickets before reporting a new one!</p> |
| 101 | </py:if> |
| 102 | ${select('*')} |
| 103 | </form> |
| 106 | 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: |
| 107 | {{{ |
| 108 | #!xml |
| 109 | <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')" |
| 110 | xmlns:xi="http://www.w3.org/2001/XInclude"> |
| 111 | <py:if test="req.environ['PATH_INFO'] == '/newticket' and (not 'preview' in req.args)"> |
| 112 | <xi:include href="site_newticket.cs"><xi:fallback /></xi:include> |
| 113 | </py:if> |
| 114 | ${select('*')} |
| 115 | </form> |
| 116 | }}} |
| 117 | |
| 118 | Also 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. |

109 | | == Main Templates == |
110 | | |
111 | | It is also possible to use your own modified versions of the Trac [http://www.clearsilver.net/ ClearSilver] templates. Note though that this technique is not recommended because it makes upgrading Trac rather problematic: there are unfortunately several dependencies between the templates and the application code, such as the name of form fields and the structure of the template data, and these are likely to change between different versions of Trac. |
112 | | |
113 | | If you absolutely need to use modified templates, copy the template files from the default templates directory (usually in found in `$prefix/share/trac/templates`) into the `templates` directory of the project environment. Then modify those copies to get the desired results. |
| 169 | For [wiki:TracStandalone], you'll need to set up the `TRAC_ENV_INDEX_TEMPLATE` environment variable in the shell used to launch tracd: |
| 170 | - Unix |
| 171 | {{{ |
| 172 | #!sh |
| 173 | $ export TRAC_ENV_INDEX_TEMPLATE=/path/to/template |
| 174 | }}} |
| 175 | - Windows |
| 176 | {{{ |
| 177 | #!sh |
| 178 | $ set TRAC_ENV_INDEX_TEMPLATE=/path/to/template |
| 179 | }}} |
