    67105TracLinks 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. 
    68106 
    69 The following sections describe the individual link types in detail, as well as several notes advanced usage of links. 
    70  
    71 == attachment: links == 
    72  
    73 The link syntax for attachments is as follows: 
    74  * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object 
    75  * !attachment:wiki:MyPage:the_file.txt creates a link to the attachment the_file.txt of the !MyPage wiki page 
    76  * !attachment:ticket:753:the_file.txt creates a link to the attachment the_file.txt of the ticket 753 
    77  
    78 == source: links == 
    79  
    80 The default behavior for a source:/some/path link is to open the directory browser  
    81 if the path points to a directory and otherwise open the log view. 
    82  
    83 It's also possible to link directly to a specific revision of a file like this: 
    84  - `source:/some/file@123` - link to the file's revision 123 
    85  - `source:/some/file@head` - link explicitly to the latest revision of the file 
    86  
    87 If the revision is specified, one can even link to a specific line number: 
    88  - `source:/some/file@123#L10` 
    89  - `source:/tag/0.10@head#L10` 
    90  
    91 Finally, one can also highlight an arbitrary set of lines: 
    92  - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103. 
    93 ''(since 0.11)'' 
    94  
    95 == export: links == 
    96  
    97 To 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: 
    98  * `export:/some/file` - get the HEAD revision of the specified file 
    99  * `export:123:/some/file` - get revision 123 of the specified file 
    100  * `export:/some/file@123` - get revision 123 of the specified file 
    101  
    102 This can be very useful for displaying HTML documentation with correct stylesheets and images, in case that has been checked in the repository. 
    103  
    104 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 `source:/some/dir`. 
    105  
    106 == search: and query: links == 
    107  
    108 See TracSearch#SearchLinks and TracQuery#UsingTracLinks 
    109  
    110 == !SubWiki links == 
    111 To create a SubWiki link to a SubWiki-page just use a '/': 
    112 {{{ 
    113  [wiki:WikiPage/SubWikiPage]. 
    114 }}} 
    115  
    116 == InterWiki links == 
     107 
     108== Advanced use of TracLinks == 
     109 
     110=== Relative links === 
     111 
     112To create a link to a specific anchor in a page, use '#': 
     113{{{ 
     114 [#Relativelinks relative links] or [[#Relativelinks|relative links]] 
     115}}} 
     116Displays: 
     117  [#Relativelinks relative links] or [[#Relativelinks|relative links]] 
     118 
     119Hint: 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. 
     120 
     121To create a link to a [trac:SubWiki SubWiki]-page just use a '/': 
     122{{{ 
     123 WikiPage/SubWikiPage or ./SubWikiPage 
     124}}} 
     125 
     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. 
     152 
     153=== InterWiki links === 
    117154 
    118155Other 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. 
    119156 
    120 == InterTrac links == 
    121  
    122 Any of the above form 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. See InterTrac for details.  
    123  
    124  
    125 == Server-relative links == 
    126  
    127 It is often useful to be able to link to objects on your server that have no built-in 
    128 Trac linking mechanism, such as static resources, a `/register` page, etc. This 
    129 can be achieved by simply using either an absolute path from the server root,  
    130 or a relative link from the URL of the current page: 
    131  
    132 {{{ 
    133 [../newticket newticket] 
    134 [/ home] 
    135 }}} 
    136  
    137 Display: [../newticket newticket] [/ home] 
    138  
    139 == Quoting space in TracLinks == 
     157=== InterTrac links === 
     158 
     159This can be seen as a kind of InterWiki link specialized for targeting other Trac projects. 
     160 
     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.  
     165 
     166=== Server-relative links === 
     167 
     168It is often useful to be able to link to objects in your project that 
     169have no built-in Trac linking mechanism, such as static resources, `newticket`, 
     170a shared `/register` page on the server, etc. 
     171 
     172To link to resources inside the project, use either an absolute path from the project root,  
     173or a relative link from the URL of the current page (''Changed in 0.11''): 
     174 
     175{{{ 
     176[/newticket Create a new ticket] or [[//newticket|Create a new ticket]] 
     177[/ home] or [[/|home]] 
     178}}} 
     179 
     180Display: [/newticket Create a new ticket] or [[//newticket|Create a new ticket]] 
     181[/ home] or [[/|home]] 
     182 
     183To link to another location on the server (possibly outside the project but on the same host), use the `//` prefix (''Changed in 0.11''): 
     184 
     185{{{ 
     186[//register Register Here] or [[//register|Register Here]] 
     187}}} 
     188 
     189Display: [//register Register Here] or [[//register|Register Here]] 
     190 
     191=== Quoting space in TracLinks === 
    140192 
    141193Immediately after a TracLinks prefix, targets containing space characters should 
     
    145197 * !attachment:'the file.txt' or 
    146198 * !attachment:"the file.txt"  
    147  * !attachment:"ticket:123:the file.txt"  
    148  
    149 == Where to use TracLinks == 
    150 You can use TracLinks in: 
    151  
    152  * Source code (Subversion) commit messages 
    153  * Wiki pages 
    154  * Full descriptions for tickets, reports and milestones 
    155  
    156 and any other text fields explicitly marked as supporting WikiFormatting. 
    157  
    158 == Escaping Links == 
     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: 
     202 * ![[The whitespace convention]] 
     203 * ![[attachment:the file.txt]] 
     204 
     205=== Escaping Links === 
    159206 
    160207To prevent parsing of a !TracLink, you can escape it by preceding it with a '!' (exclamation mark). 
     
    168215 ![42] is not a link either. 
    169216 
     217 
     218=== Parameterized Trac links === 
     219 
     220Many 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. 
     221 
     222Trac links can support an arbitrary set of parameters, written in the same way as they would be for the corresponding URL. Some examples: 
     223 - `wiki:WikiStart?format=txt` 
     224 - `ticket:1?version=1` 
     225 - `[/newticket?component=module1 create a ticket for module1]` 
     226 - `[/newticket?summary=Add+short+description+here create a ticket with URL with spaces]` 
     227 
     228 
     229== TracLinks Reference == 
     230The following sections describe the individual link types in detail, as well as notes on advanced usage of links. 
     231 
     232=== attachment: links === 
     233 
     234The link syntax for attachments is as follows: 
     235 * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object 
     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. 
     244 
     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`

     269Besides 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. 
     270 
     271Example:  
     272 - `ticket:5000-6000` 
     273 - `ticket:1,150`

     276 
     277=== timeline: links === 
     278 
     279Links 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 alternatively you can specify your local time, followed by your timezone if you don't want to compute the UTC time. 
     280 
     281Examples: 
     282 - `timeline:2008-01-29` 
     283 - `timeline:2008-01-29T15:48` 
     284 - `timeline:2008-01-29T15:48Z` 
     285 - `timeline:2008-01-29T16:48+01`

     293=== Version Control related links === 
     294 
     295It 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). 
     296 
     297For 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'`. 
     298 
     299==== source: links ==== 
     300 ''aliases:'' `browser:`, `repos:` 
     301 
     302The default behavior for a source:/some/path link is to open the browser in that directory directory  
     303if the path points to a directory or to show the latest content of the file. 
     304 
     305It's also possible to link directly to a specific revision of a file like this: 
     306 - `source:/some/file@123` - link to the file's revision 123 
     307 - `source:/some/file@head` - link explicitly to the latest revision of the file 
     308 
     309If the revision is specified, one can even link to a specific line number: 
     310 - `source:/some/file@123#L10` 
     311 - `source:/tag/0.10@head#L10` 
     312 
     313Finally, one can also highlight an arbitrary set of lines: 
     314 - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103. 
     315   ''(since 0.11)'' 
     316 
     317Note 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)'' 
     318 
     319==== export: links ==== 
     320 
     321To 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: 
     322 * `export:/some/file` - get the HEAD revision of the specified file 
     323 * `export:123:/some/file` - get revision 123 of the specified file 
     324 * `export:/some/file@123` - get revision 123 of the specified file 
     325 
     326This 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 `[browser] render_unsafe_content = yes` (see TracIni#browser-section), otherwise Trac will force the files to be downloaded as attachments for security concerns.  
     327 
     328If 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`). 
     329 
     330==== log: links ==== 
     331 
     332The `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. 
     333 - `log:/` - the latest revisions starting at the root of the repository 
     334 - `log:/trunk/tools` - the latest revisions in `trunk/tools` 
     335 - `log:/trunk/tools@10000` - the revisions in `trunk/tools` starting from  revision 10000 
     336 - `log:@20788,20791:20795` - list revision 20788 and the revisions from 20791 to 20795  
     337 - `log:/trunk/tools@20788,20791:20795` - list revision 20788 and the revisions from 20791 to 20795 which affect the given path 
     338 
     339There are short forms for revision ranges as well: 
     340 - `[20788,20791:20795]` 
     341 - `[20788,20791:20795/trunk/tools]` 
     342 - `r20791:20795` (but not `r20788,20791:20795` nor `r20791:20795/trunk`) 
     343 
     344Finally, note that in all of the above, a revision range can be written either as `x:y` or `x-y`. 
     345 
     346In the presence of multiple repositories, the name of the repository should be specified as the first part of the path, e.g. `log:repos/branches` or `[20-40/repos]`.
