| 11 | | |
| 12 | | 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''. |
| 13 | | |
| 14 | | '''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. |

| 20 | | 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'. |

| 57 | | Trac is using [http://genshi.edgewall.org Genshi] as the templating engine. Say you want to add a link to a custom stylesheet, and then your own header and footer. Save the following content as `site.html` inside your projects `templates/` directory (each Trac project can have their own `site.html`), eg `/path/to/env/templates/site.html`: |
| 58 | | |
| 59 | | {{{#!xml |
| 60 | | <html xmlns="http://www.w3.org/1999/xhtml" |
| 61 | | xmlns:py="http://genshi.edgewall.org/" |
| 62 | | py:strip=""> |

| 64 | | <!--! Add site-specific style sheet --> |
| 65 | | <head py:match="head" py:attrs="select('@*')"> |
| 66 | | ${select('*|comment()|text()')} |
| 67 | | <link rel="stylesheet" href="${href.chrome('site/style.css')}" /> |
| 68 | | </head> |
| 69 | | |

| | 56 | == Site Appearance |
| | 57 | |
| | 58 | Trac is using [http://jinja.pocoo.org/ Jinja2] as the templating engine. |
| | 59 | |
| | 60 | We have put in place a number of "placeholder" in the form of "include" directives. These files don't need to exist, but if they do, their content will be processed by Jinja2 as well. As such, they can make use of other "include" directives, or any other feature of Jinja2 to generate dynamic content. |
| | 61 | |
| | 62 | There are three such placeholder templates: |
| | 63 | - `site_head.html`, which can be used to add content inside the generated `<head>` element |
| | 64 | - `site_header.html`, which can be used to **prepend** content inside the generated `<body>` element, before the standard content generated by Trac |
| | 65 | - `site_footer.html`, which can be used to **append** content inside the generated `<body>` element, after the standard content generated by Trac |
| | 66 | |
| | 67 | Say you want to add a link to a custom stylesheet, and then your own header and footer. Save the following content as `site_head.html`, `site_header.html` and `site_footer.html` inside your projects `templates/` directory (each Trac project can have their own "placeholder" files) e.g. `/path/to/env/templates/site_head.html`: |
| | 68 | |
| | 69 | `site_head.html`: |
| | 70 | {{{#!xml |
| | 71 | <!-- site_head.html: Add site-specific style sheet --> |
| | 72 | <link rel="stylesheet" href="${href.chrome('site/style.css')}" /> |
| | 73 | <!-- /site_head.html --> |
| | 74 | }}} |
| | 75 | |
| | 76 | `site_header.html`: |
| | 77 | {{{#!xml |
| | 78 | <!-- site_header.html: Add site-specific header --> |
| 82 | | </body> |
| 83 | | </html> |
| 84 | | }}} |
| 85 | | |
| 86 | | Notice that XSLT bears some similarities with Genshi templates. However, there are some Trac specific features, for example the `${href.chrome('site/style.css')}` attribute references `style.css` in the environment's `htdocs/` directory. In a similar fashion `${chrome.htdocs_location}` is used to specify the common `htdocs/` directory belonging to a Trac installation. That latter location can however be overriden using the [[TracIni#trac-section|[trac] htdocs_location]] configuration setting. |
| 87 | | |
| 88 | | `site.html` is one file to contain all your modifications. It usually works using the `py:match` directive (element or attribute), and it allows you to modify the page as it renders. The matches hook onto specific sections depending on what it tries to find and modify them. |
| 89 | | See [http://groups.google.com/group/trac-users/browse_thread/thread/70487fb2c406c937/ this thread] for a detailed explanation of the above example `site.html`. |
| 90 | | A `site.html` can contain any number of such `py:match` sections for whatever you need to modify. This is all Genshi, so the [http://genshi.edgewall.org/wiki/Documentation/xml-templates.html docs on the exact syntax] can be found there. |
| | 91 | <!-- /site_footer.html --> |
| | 92 | }}} |
| | 93 | |
| | 94 | Notice that as Jinja2 is mostly content agnostic, you are free to open some `<div>` element in the `site_header.html` file and only close it in `site_footer.html` file. |
| | 95 | Besides, as in any other Trac Jinja2 template, you can use some Trac specific features, for example the `${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 overridden using the [TracIni#trac-htdocs_location-option "[trac] htdocs_location"] setting. |
| 94 | | {{{#!xml |
| 95 | | <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')"> |
| 96 | | <py:if test="req.path_info == '/newticket' and (not 'preview' in req.args)"> |
| 97 | | <p>Please make sure to search for existing tickets before reporting a new one!</p> |
| 98 | | </py:if> |
| 99 | | ${select('*')} |
| 100 | | </form> |
| 101 | | }}} |
| 102 | | |
| 103 | | This example illustrates a technique of using `req.path_info` to limit scope of changes to one view only. For instance, to make changes in `site.html` only for timeline and avoid modifying other sections - use `req.path_info == '/timeline'` condition in `<py:if>` test. |
| 104 | | |
| 105 | | More examples snippets for `site.html` can be found at [trac:wiki:CookBook/SiteHtml CookBook/SiteHtml]. |
| | 99 | - first we need to introduce the extra "content" of this notice, if it's appropriate for the request. For that, we add this snippet in the `site_footer.html` placeholder file: |
| | 100 | {{{#!xml |
| | 101 | # if req.path_info == '/newticket' and 'preview' not in req.args: |
| | 102 | <p id="ntg">Please make sure to search for existing tickets before reporting a new one!</p> |
| | 103 | # endif |
| | 104 | }}} |
| | 105 | - second, we need to dynamically alter the rest of the content in order to position that notice at the desired location. For that, we add this snippet to the `site_head.html` placeholder file: |
| | 106 | |
| | 107 | {{{#!xml |
| | 108 | <script> |
| | 109 | jQuery(function($) { |
| | 110 | var $ntg = $("#newticketguide"); |
| | 111 | if ($ntg.length) |
| | 112 | $("#propertyform").prepend($ntg.detach()); |
| | 113 | }); |
| | 114 | </script> |
| | 115 | }}} |
| | 116 | |
| | 117 | This example illustrates a technique of using `req.path_info` to limit scope of changes to one view only. For instance, to make changes only for timeline and avoid modifying other sections, use `req.path_info == '/timeline'` as the condition in a `# if` test. |
| | 118 | |
| | 119 | More examples snippets for placeholder files can be found at [trac:wiki:CookBook/SiteHtml CookBook/SiteHtml]. |
| 109 | | If the environment is upgraded from 0.10 and a `site_newticket.cs` file already exists, it can be loaded using a workaround, provided it contains no [trac:ClearSilver] processing. In addition, as only one element can be imported, the content needs a 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: |
| 110 | | {{{#!xml |
| 111 | | <form py:match="div[@id='content' and @class='ticket']/form" py:attrs="select('@*')" |
| 112 | | xmlns:xi="http://www.w3.org/2001/XInclude"> |
| 113 | | <py:if test="req.path_info == '/newticket' and (not 'preview' in req.args)"> |
| 114 | | <xi:include href="site_newticket.cs"><xi:fallback /></xi:include> |
| 115 | | </py:if> |
| 116 | | ${select('*')} |
| 117 | | </form> |
| 118 | | }}} |
| 119 | | |
| 120 | | Also note that the `site.html`, despite its name, can be put in a shared templates directory, see the [[TracIni#inherit-section|[inherit] templates_dir]] option. This could provide easier maintenance (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. |
| | 123 | === Sharing Templates in Multiple Environments |
| | 124 | |
| | 125 | The `site_*.html` templates, despite their name, can be put in a shared templates directory, see the [[TracIni#inherit-templates_dir-option|[inherit] templates_dir]] option. This could provide easier maintenance, as global `site_head.html`, `site_header.html` and `site_footer.html` files can be made to `# include` any other local existing header, footer and newticket snippets. |
| 189 | | 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 recommended way is to use a `site.html` template whenever possible, see [#SiteAppearance]. 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. |
| 190 | | |
| 191 | | With that word of caution, any Trac template may be copied and customized. The default Trac templates are located inside the installed Trac egg, such as `/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. |
| 192 | | |
| 193 | | However, do not edit templates or site resources inside the Trac egg |
| | 196 | 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.

| | 200 | However, do not edit templates or site resources inside the Trac egg/wheel. Reinstalling Trac overwrites your modifications. Instead use one of these alternatives: |
| 195 | | * 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. |
| 196 | | |
| 197 | | Trac resolves requests for a template by first looking inside the project, then in any inherited templates location, and finally inside the Trac egg |
