    78105TracLinks are a very simple idea, but actually allow quite a complex network of information. 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.
    … …  
    85112To create a link to a specific anchor in a page, use '#':
    86113{{{
    87  [#Relativelinks relative links]
     114 [#Relativelinks relative links] or [[#Relativelinks|relative links]]
    88115}}}
    89116Displays:
    90   [#Relativelinks relative links]
     117  [#Relativelinks relative links] or [[#Relativelinks|relative links]]
    91118
    92119Hint: when you move 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 `#...` part inside a relative link to an anchor.
    93120
    94 To create a link to a SubWiki-page just use a '/':
     121To create a link to a [trac:SubWiki SubWiki]-page just use a '/':
    95122{{{
    96123 WikiPage/SubWikiPage or ./SubWikiPage
    97124}}}
    98125
    99 To link from a SubWiki page to a parent, simply use a '..':
    100 {{{
    101   [..]
    102 }}}
    103 
    104 To link from a SubWiki page to a sibling page, use a '../':
    105 {{{
    106   [../Sibling see next sibling]
    107 }}}
    108 
    109 ''(Changed in 0.11)'' Note that in Trac 0.10, using e.g. `[../newticket]`  may have worked for linking to the /newticket top-level URL, but now in 0.11 it will stay in the wiki namespace and link to a sibling page. See [#Server-relativelinks] for the new syntax.
     126To link from a [trac:SubWiki SubWiki] page to a parent, simply use a '..':
     127{{{
     128  [..] or [[..]]
     129}}}
     130  [..] or [[..]]
     131
     132To link from a [trac:SubWiki SubWiki] page to a [=#sibling sibling] page, use a '../':
     133{{{
     134  [../Sibling see next sibling] or [[../Sibling|see next sibling]]
     135}}}
     136  [../Sibling see next sibling] or [[../Sibling|see next sibling]]
     137
     138But in practice you often won't need to add the `../` prefix to link to a sibling page.
     139For resolving the location of a wiki link, it's the target page closest in the hierarchy
     140to the page where the link is written which will be selected. So for example, within
     141a sub-hierarchy, a sibling page will be targeted in preference to a toplevel page.
     142This makes it easy to copy or move pages to a sub-hierarchy by [[WikiNewPage#renaming|renaming]] without having to adapt the links.
     143
     144In order to link explicitly to a [=#toplevel toplevel] Wiki page,
     145use the `wiki:/` prefix.
     146Be careful **not** to use the `/` prefix alone, as this corresponds to the
     147[#Server-relativelinks] syntax and with such a link you will lack the `/wiki/`
     148part in the resulting URL.
     149
     150''(Changed in 0.11)'' Note that in Trac 0.10, using e.g. `[../newticket]`  may have worked for linking to the `/newticket` top-level URL, but since 0.11, such a link will stay in the wiki namespace and therefore link to a sibling page.
     151See [#Server-relativelinks] for the new syntax.
    110152
    111153=== InterWiki links ===
    … …  
    117159This can be seen as a kind of InterWiki link specialized for targeting other Trac projects.
    118160
    119 Any type of Trac links could be written in one Trac environment and actually refer to resources present in another Trac environment, provided the Trac link is prefixed by the name of that other Trac environment followed by a colon. That other Trac environment must be registered, under its name or an alias. See InterTrac for details.
    120 
    121 A distinctive advantage of InterTrac links over InterWiki links is that the shorthand form of Trac links usually have a way to understand the InterTrac prefixes. For example, links to Trac tickets can be written #T234 (if T was set as an alias for Trac), links to Trac changesets can be written [trac 1508].
     161Any type of Trac link can be written in one Trac environment and actually refer to resources in another Trac environment. All that is required is to prefix the Trac link with the name of the other Trac environment followed by a colon. The other Trac environment must be registered on the InterTrac page.
     162
     163A distinctive advantage of InterTrac links over InterWiki links is that the shorthand form of Trac links (e.g. `{}`, `r`, `#`) can also be used. For example if T was set as an alias for Trac, links to Trac tickets can be written #T234, links to Trac changesets can be written [trac 1508].
     164See InterTrac for the complete details.

     199 * !attachment:"the file.txt:ticket:123"
     200
     201Note that by using [trac:WikiCreole] style links, it's quite natural to write links containing spaces:

    171219
    172 The Trac links target Trac resources which have generally more than one way to be rendered, according to some extra parameters. For example, a Wiki page can accept a `version` or a `format` parameter, a report can make use of dynamic variables, etc.
    173 
    174 Any Trac links can support an arbitrary set of parameters, written in the same way as they would be for the corresponding URL. Some examples:

    182231
    183232=== attachment: links ===
    … …  
    185234The link syntax for attachments is as follows:
    186235 * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object
    187  * !attachment:wiki:MyPage:the_file.txt creates a link to the attachment the_file.txt of the !MyPage wiki page
    188  * !attachment:ticket:753:the_file.txt creates a link to the attachment the_file.txt of the ticket 753
     236 * !attachment:the_file.txt:wiki:MyPage creates a link to the attachment the_file.txt of the !MyPage wiki page
     237 * !attachment:the_file.txt:ticket:753 creates a link to the attachment the_file.txt of the ticket 753
     238
     239Note that the older way, putting the filename at the end, is still supported: !attachment:ticket:753:the_file.txt.
     240
     241If you'd like to create a direct link to the content of the attached file instead of a link to the attachment page, simply use `raw-attachment:` instead of `attachment:`.
     242
     243This can be useful for pointing directly to an HTML document, for example. Note that for this use case, you'd have to allow the web browser to render the content by setting `[attachment] render_unsafe_content = yes` (see TracIni#attachment-section). Caveat: only do that in environments for which you're 100% confident you can trust the people who are able to attach files, as otherwise this would open up your site to [wikipedia:Cross-site_scripting cross-site scripting] attacks.

     245See also [#export:links].
     246
     247=== comment: links ===
     248
     249When you're inside a given ticket, you can simply write e.g. !comment:3 to link to the third change comment.
     250It is possible to link to a comment of a specific ticket from anywhere using one of the following syntax:
     251 - `comment:3:ticket:123`
     252 - `ticket:123#comment:3` (note that you can't write `#123#!comment:3`!)
     253It is also possible to link to the ticket's description using one of the following syntax:
     254 - `comment:description` (within the ticket)
     255 - `comment:description:ticket:123`
     256 - `ticket:123#comment:description`
     257
     258=== htdocs: links ===
     259

    222296
    223297=== Version Control related links ===
     298
     299It should be noted that multiple repository support works by creating a kind of virtual namespace for versioned files in which the toplevel folders correspond to the repository names. Therefore, in presence of multiple repositories, a ''/path'' 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 latter "wins". One can always access such folder by fully qualifying it (the default repository can be an alias of a named repository, or conversely, it is always possible to create an alias for the default repository, ask your Trac administrator).
     300
     301For example, `source:/trunk/COPYING` targets the path `/trunk/COPYING` in the default repository, whereas `source:/projectA/trunk/COPYING` targets the path `/trunk/COPYING` in the repository named `projectA`. This can be the same file if `'projectA'` is an alias to the default repository or if `''` (the default repository) is an alias to `'projectA'`.
     302
    224303==== source: links ====
    225 
    226 The default behavior for a source:/some/path link is to open the directory browser
    227 if the path points to a directory and otherwise open the log view.
     304 ''aliases:'' `browser:`, `repos:`
     305
     306The default behavior for a source:/some/path link is to open the browser in that directory directory
     307if the path points to a directory or to show the latest content of the file.
    228308
    229309It's also possible to link directly to a specific revision of a file like this:
    … …  
    237317Finally, one can also highlight an arbitrary set of lines:
    238318 - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103.
    239 ''(since 0.11)''
     319   ''(since 0.11)''
     320
     321Note that in presence of multiple repositories, the name of the repository is simply integrated in the path you specify for `source:` (e.g. `source:reponame/trunk/README`). ''(since 0.12)''
    240322
    241323==== export: links ====

    255337 - `log:/` - the latest revisions starting at the root of the repository
    256338 - `log:/trunk/tools` - the latest revisions in `trunk/tools`
    257339 - `log:/trunk/tools@10000` - the revisions in `trunk/tools` starting from  revision 10000
    258  - `log:@20788,20791:20795` - list revision 20788 and the 20791 to 20795 revision range
    259  - `log:/trunk/tools@20788,20791:20795` - list revision 20788 and the revisions from the 20791 to 20795 range which affect the given path
