In practice, it's very intuitive and simple to use, and we've found the "link trail" extremely helpful to better understand what's happening in a project or why a particular change was made. </p> <h2 class="section" id="AdvanceduseofTracLinks">Advanced use of <a class="wiki" href="/wiki/TracLinks">TracLinks</a></h2> <h3 class="section" id="Relativelinks">Relative links</h3> <p> To create a link to a <a href="https://trac.edgewall.org/intertrac/SubWiki" title="SubWiki in The Trac Project">SubWiki</a>-page just use a '/': </p> <pre class="wiki"> WikiPage/SubWikiPage or ./SubWikiPage </pre><p> To link from a <a href="https://trac.edgewall.org/intertrac/SubWiki" title="SubWiki in The Trac Project">SubWiki</a> page to a parent, simply use a '..': </p> <pre class="wiki"> [..] or [[..]] </pre><blockquote> <p> <a href="/wiki">..</a> or <a href="/wiki">..</a> </p> </blockquote> <p> To link from a <a href="https://trac.edgewall.org/intertrac/SubWiki" title="SubWiki in The Trac Project">SubWiki</a> page to a <span class="wikianchor" id="sibling">sibling</span> page, use a '../': </p> <pre class="wiki"> [../Sibling see next sibling] or [[../Sibling|see next sibling]] </pre><blockquote> <p> <a class="missing wiki" href="/wiki/Sibling" rel="nofollow">see next sibling</a> or <a class="missing wiki" href="/wiki/Sibling" rel="nofollow">see next sibling</a> </p> </blockquote> <p> But in practice you often won't need to add the <code>../</code> prefix to link to a sibling page. For resolving the location of a wiki link, it's the target page closest in the hierarchy to the page where the link is written which will be selected. So for example, within a sub-hierarchy, a sibling page will be targeted in preference to a top-level page. This makes it easy to copy or move pages to a sub-hierarchy by <a class="wiki" href="/wiki/WikiNewPage#renaming">renaming</a> without having to adapt the links. </p> <p> To link explicitly to a <span class="wikianchor" id="toplevel">toplevel</span> Wiki page, use the <code>wiki:/</code> prefix. Be careful <strong>not</strong> to use the <code>/</code> prefix alone, as this corresponds to the <a class="wiki" href="/wiki/TracLinks#Server-relativelinks">#Server-relativelinks</a> syntax and with such a link you will lack the <code>/wiki/</code> part in the resulting URL. A link such as <code>[../newticket]</code> will stay in the wiki namespace and therefore link to a sibling page. </p> <h3 class="section" id="Linkanchors">Link anchors</h3> <p> To create a link to a specific anchor in a page, use <code>#</code>: </p> <pre class="wiki"> [#Linkanchors Link anchors] or [[#Linkanchors|Link anchors]] </pre><blockquote> <p> <a class="wiki" href="/wiki/TracLinks#Linkanchors">Link anchors</a> or <a class="wiki" href="/wiki/TracLinks#Linkanchors">Link anchors</a> </p> </blockquote> <p> To create an anchor in a page, use <code>[=#...]</code>: </p> <pre class="wiki"> [=#myanchor my anchor] or empty form [=#myanchor] </pre><blockquote> <p> <span class="wikianchor" id="myanchor">my anchor</span> or empty form <span class="wikianchor" id="myanchor"></span> </p> </blockquote> <p> Hint: when you hover your mouse over the title of a section, a '¶' character will be displayed. This is a link to that specific section and you can use this to copy the <code>#...</code> part inside a relative link to an anchor. </p> <p> To create a link to the first or last occurrence of a term on a page, use a <em>pseudo anchor</em> starting with <code>#/</code> or <code>#?</code>: </p> <pre class="wiki"> [#/Milestone first occurrence of Milestone] or [#?Milestone last occurrence of Milestone] </pre><blockquote> <p> <a class="wiki" href="/wiki/TracLinks#/Milestone">first occurrence of Milestone</a> or <a class="wiki" href="/wiki/TracLinks#?Milestone">last occurrence of Milestone</a> </p> </blockquote> <p> This will also highlight all other matches on the linked page.

All that is required is to prefix the Trac link with the name of the other Trac environment followed by a colon.

For example, if T was set as an alias for Trac, then links to Trac tickets can be written as <a href="https://trac.edgewall.org/intertrac/ticket%3A234" title="ticket:234 in The Trac Project">#T234</a>, and links to Trac changesets can be written as <a href="https://trac.edgewall.org/intertrac/changeset%3A1508" title="changeset:1508 in The Trac Project">[trac 1508]</a>.

Note that for this use case, you'd have to allow the web browser to render the content by setting <a class="wiki" href="/wiki/TracIni#attachment-render_unsafe_content-option">[attachment] render_unsafe_content</a> = <code>enabled</code>. Caveat: only do that in environments for which you're 100% confident you can trust the people who are able to attach files, as this opens up your site to <a class="ext-link" href="https://en.wikipedia.org/wiki/Cross-site_scripting"><span class="icon"></span>cross-site scripting</a> attacks. </p> <p> See also <a class="wiki" href="/wiki/TracLinks#export:links">#export:links</a>. </p> <h3 class="section" id="comment:links">comment: links</h3> <p> When you're inside a given ticket, you can simply write e.g. comment:3 to link to the third change comment.

Therefore, in presence of multiple repositories, a <em>/path</em> specification in the syntax of links detailed below should start with the name of the repository. If omitted, the default repository is used. In case a toplevel folder of the default repository has the same name as a repository, the link directs to the latter. One can always access such folder by fully qualifying it. The default repository can be an alias of a named repository, or conversely, there may be one or more aliases for the default repository, ask your Trac administrator. </p> <p> For example, <code>source:/trunk/COPYING</code> targets the path <code>/trunk/COPYING</code> in the default repository, whereas <code>source:/projectA/trunk/COPYING</code> targets the path <code>/trunk/COPYING</code> in the repository named <code>projectA</code>. This can be the same file if <code>'projectA'</code> is an alias to the default repository or if <code>''</code> (the default repository) is an alias to <code>'projectA'</code>. </p> <h4 class="section" id="source:links">source: links</h4> <blockquote> <p> <em>aliases:</em> <code>browser:</code>, <code>repos:</code> </p> </blockquote> <p> The default behavior for a <code>source:/some/path link</code> is to open the browser in that directory directory if the path points to a directory or to show the latest content of the file. </p> <p> It's also possible to link directly to a specific revision of a file like this: </p> <ul><li><code>source:/some/file@123</code> - link to the file's revision 123 </li><li><code>source:/some/file@head</code> - link explicitly to the latest revision of the file </li><li><code>source:/some/file@named-branch</code> - link to latest revision of the specified file in <code>named-branch</code> (DVCS such as Git or Mercurial) </li></ul><p> If the revision is specified, one can even link to a specific line number: </p> <ul><li><code>source:/some/file@123#L10</code> </li><li><code>source:/tag/0.10@head#L10</code> </li><li><code>source:/some/file@named-branch#L10</code> </li></ul><p> Finally, one can also highlight an arbitrary set of lines: </p> <ul><li><code>source:/some/file@123:10-20,100,103#L99</code> - highlight lines 10 to 20, and lines 100 and 103, and target line 99 </li><li>or without version number (the <code>@</code> is still needed): <code>source:/some/file@:10-20,100,103#L99</code>. Version can be omitted when the path is pointing to a source file that will no longer change (like <code>source:/tags/...</code>), otherwise it's better to specify which lines of <em>which version</em> of the file you're talking about. </li></ul><p> Note that in presence of multiple repositories, the name of the repository is simply integrated in the path you specify for <code>source:</code> (e.g. <code>source:reponame/trunk/README</code>). <em>(since 0.12)</em> </p> <h4 class="section" id="export:links">export: links</h4> <p> To force the download of a file in the repository, as opposed to displaying it in the browser, use the <code>export</code> link. Several forms are available: </p> <ul><li><code>export:/some/file</code> - get the HEAD revision of the specified file </li><li><code>export:123:/some/file</code> - get revision 123 of the specified file </li><li><code>export:/some/file@123</code> - get revision 123 of the specified file </li><li><code>export:/some/file@named-branch</code> - get latest revision of the specified file in <code>named-branch</code> (DVCS such as Git or Mercurial). </li></ul><p> This can be very useful for displaying XML or HTML documentation with correct stylesheets and images, in case that has been checked in into the repository. Note that for this use case, you'd have to allow the web browser to render the content by setting <a class="wiki" href="/wiki/TracIni#browser-render_unsafe_content-option">[browser] render_unsafe_content</a> = <code>enabled</code>, otherwise Trac will force the files to be downloaded as attachments for security concerns. </p> <p> If the path is to a directory in the repository instead of a specific file, the source browser will be used to display the directory (identical to the result of <code>source:/some/dir</code>). </p> <h4 class="section" id="log:links">log: links</h4> <p> The <code>log:</code> links are used to display revision ranges.
