    4 TracLinks are a fundamental feature of Trac, because they allow easy hyperlinking between the various entities in the system—such as tickets, reports, changesets, Wiki pages, milestones, and source files—from anywhere WikiFormatting is used.
    5 
    6 TracLinks are generally of the form '''type:id''' (where ''id'' represents the
    7 number, name or path of the item) though some frequently used kinds of items
    8 also have short-hand notations.

    105103TracLinks 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.

    112109To create a link to a [trac:SubWiki SubWiki]-page just use a '/':
    … …  
    128125
    129126But in practice you often won't need to add the `../` prefix to link to a sibling page.
    130 For resolving the location of a wiki link, it's the target page closest in the hierarchy
    131 to the page where the link is written which will be selected. So for example, within
    132 a sub-hierarchy, a sibling page will be targeted in preference to a toplevel page.
     127For 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 toplevel page.
    133128This makes it easy to copy or move pages to a sub-hierarchy by [[WikiNewPage#renaming|renaming]] without having to adapt the links.
    134129
    135 In order to link explicitly to a [=#toplevel toplevel] Wiki page,
    136 use the `wiki:/` prefix. Be careful **not** to use the `/` prefix alone, as this corresponds to the [#Server-relativelinks] syntax and with such a link you will lack the `/wiki/` part in the resulting URL. A link such as `[../newticket]` will stay in the wiki namespace and therefore link to a sibling page.

    182 === InterWiki links ===
    183 
    184 Other prefixes can be defined freely and made to point to resources in other Web applications. The definition of those prefixes as well as the URLs of the corresponding Web applications is defined in a special Wiki page, the InterMapTxt page. Note that while this could be used to create links to other Trac environments, there's a more specialized way to register other Trac environments which offers greater flexibility.

    195 === Server-relative links ===
    196 
    197 It is often useful to be able to link to objects in your project that
    198 have no built-in Trac linking mechanism, such as static resources, `newticket`,
    199 a shared `/register` page on the server, etc.
    200 
    201 To link to resources inside the project, use either an absolute path from the project root,
    202 or a relative link from the URL of the current page (''Changed in 0.11''):

    220 === Quoting space in TracLinks ===
    221 
    222 Immediately after a TracLinks prefix, targets containing space characters should
    223 be enclosed in a pair of quotes or double quotes.

     224=== Escaping Links
    235225
    236226To prevent parsing of a !TracLink, you can escape it by preceding it with a '!' (exclamation mark).

    244234 ![42] is not a link either.

    248237
    249238Many Trac resources have more than one way to be rendered, depending on 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.

    288277
    289278Use `htdocs:path/to/file` to reference files in the `htdocs` directory of the Trac environment, the [TracEnvironment#DirectoryStructure web resource directory].

    301291
    302292Besides the obvious `ticket:id` form, it is also possible to specify a list of tickets or even a range of tickets instead of the `id`. This generates a link to a custom query view containing this fixed set of tickets.

     298=== timeline: links
    309299
    310300Links to the timeline can be created by specifying a date in the ISO:8601 format. The date can be optionally followed by a time specification. The time is interpreted as being UTC time, but if you don't want to compute the UTC time, you can specify a local time followed by your timezone offset relative to UTC.
    … …  
    318308 - `timeline:2008-01-29T16:48+01:00`
    319309
    320 === wiki: links ===
     310=== wiki: links
    321311
    322312See WikiPageNames and [#QuotingspaceinTracLinks quoting space in TracLinks] above. It is possible to create a link to a specific page revision using the syntax WikiStart@1.
    323313
    324 === Version Control related links ===
    325 
    326 It 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).

    327317
    328318For 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'`.

    333 The default behavior for a `source:/some/path link` is to open the browser in that directory directory
    334 if the path points to a directory or to show the latest content of the file.
     324The default behavior for a `source:/some/path link` 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.
    335325
    336326It's also possible to link directly to a specific revision of a file like this:
    … …  
    346336Finally, one can also highlight an arbitrary set of lines:
    347337 - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103, and target line 99
    348  - or without version number (the `@` is still needed): `source:/some/file@:10-20,100,103#L99`. Version can be omitted when the path is pointing to a source file that will no longer change (like `source:/tags/...`), otherwise it's better to specify which lines of //which version// of the file you're talking about
     338 - or without version number (the `@` is still needed): `source:/some/file@:10-20,100,103#L99`. Version can be omitted when the path is pointing to a source file that will no longer change (like `source:/tags/...`), otherwise it's better to specify which lines of //which version// of the file you're talking about.
    349339
    350340Note 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)''

     342==== export: links
    353343
    354344To force the download of a file in the repository, as opposed to displaying it in the browser, use the `export` link.  Several forms are available:
    … …  
    362352If 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 `source:/some/dir`).
    363353
    364 ==== log: links ====
     354==== log: links
    365355
    366356The `log:` links are used to display revision ranges. In its simplest form, it can link to the latest revisions of the specified path, but it can also support displaying an arbitrary set of revisions.
