     1= Trac Links = 
     2TracLinks 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. 
     3 
     4TracLinks are generally of the form '''type:id''' (where ''id'' represents the 
     5number, name or path of the item) though some frequently used kinds of items 
     6also have short-hand notations. 
     7 
     8Some examples: 
     9 * Tickets: '''!#1''' or '''!ticket:1''' 
     10 * Ticket comments: '''!comment:ticket:1:2'''  
     11 * Reports: '''!{1}''' or '''!report:1''' 
     12 * Changesets: '''!r1''', '''![1]''', '''!changeset:1''' or (restricted) '''![1/trunk]''', '''!changeset:1/trunk''' 
     13 * Revision log: '''!r1:3''', '''![1:3]''' or '''!log:@1:3''', '''!log:trunk@1:3''' 
     14 * Diffs (requires [milestone:0.10 0.10]): '''!diff:@1:3''', '''!diff:tags/trac-0.9.2/wiki-default//tags/trac-0.9.3/wiki-default''' or '''!diff:trunk/trac@3538//sandbox/vc-refactoring@3539''' 
     15 * Wiki pages: '''!CamelCase''' or '''!wiki:CamelCase''' 
     16 * Milestones: '''!milestone:1.0''' 
     17 * Attachment: '''!attachment:ticket:944:attachment.1073.diff''' 
     18 * Files: '''!source:trunk/COPYING''' 
     19 * A specific file revision: '''!source:/trunk/COPYING@200''' 
     20 * A particular line of a specific file revision: '''!source:/trunk/COPYING@200#L25''' 
     21Display: 
     22 * Tickets: #1 or ticket:1 
     23 * Ticket comments: comment:ticket:1:2  
     24 * Reports: {1} or report:1 
     25 * Changesets: r1, [1], changeset:1, or (restricted) [1/trunk], changeset:1/trunk 
     26 * Revision log: r1:3, [1:3] or log:@1:3, log:trunk@1:3 
     27 * Diffs (requires [milestone:0.10 0.10]): diff:@20:30, diff:tags/trac-0.9.2/wiki-default//tags/trac-0.9.3/wiki-default or diff:trunk/trac@3538//sandbox/vc-refactoring/trac@3539 
     28 * Wiki pages: CamelCase or wiki:CamelCase 
     29 * Milestones: milestone:1.0 
     30 * Attachment: attachment:ticket:944:attachment.1073.diff 
     31 * Files: source:trunk/COPYING 
     32 * A specific file revision: source:/trunk/COPYING@200 
     33 * A particular line of a specific file revision: source:/trunk/COPYING@200#L25 
     34 
     35'''Note:''' The wiki:CamelCase form is rarely used, but it can be convenient to refer to 
     36pages whose names do not follow WikiPageNames rules, i.e., single words, 
     37non-alphabetic characters, etc. See WikiPageNames for more about features specific 
     38to links to Wiki page names. 
     39 
     40Trac links using the full (non-shorthand) notation can also be given a custom 
     41link title like this: 
     42 
     43{{{ 
     44[ticket:1 This is a link to ticket number one]. 
     45}}} 
     46 
     47Display: [ticket:1 This is a link to ticket number one]. 
     48 
     49If the title is be omitted, only the id (the part after the colon) is displayed: 
     50 
     51{{{ 
     52[ticket:1] 
     53}}} 
     54 
     55Display: [ticket:1] 
     56 
     57`wiki` is the default if the namespace part of a full link is omitted (''since version 0.10''): 
     58 
     59{{{ 
     60[SandBox the sandbox] 
     61}}} 
     62 
     63Display: [SandBox the sandbox] 
     64 
     65TracLinks 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. 
     66 
     67The following sections describe the individual link types in detail, as well as several notes advanced usage of links. 
     68 
     69== attachment: links == 
     70 
     71The link syntax for attachments is as follows: 
     72 * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object 
     73 * !attachment:wiki:MyPage:the_file.txt creates a link to the attachment the_file.txt of the !MyPage wiki page 
     74 * !attachment:ticket:753:the_file.txt creates a link to the attachment the_file.txt of the ticket 753 
     75 
     76== source: links == 
     77 
     78The default behavior for a source:/some/path link is to open the directory browser  
     79if the path points to a directory and otherwise open the log view.  
     80It's also possible to link directly to a specific revision of a file like this: source:/some/file@123  
     81or like this to link to the latest revision: source:/some/file@latest. 
     82If the revision is specified, one can even link to a specific line number: source:/some/file@123#L10  
     83 
     84== search: and query: links == 
     85 
     86See TracSearch#SearchLinks and TracQuery#UsingTracLinks 
     87 
     88== !SubWiki links == 
     89To create a SubWiki link to a SubWiki-page just use a '/': 
     90{{{ 
     91 [wiki:WikiPage/SubWikiPage]. 
     92}}} 
     93 
     94== InterWiki links == 
     95 
     96Other 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. 
     97 
     98== InterTrac links == 
     99 
     100Any 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.  
     101 
     102 
     103== Server-relative links == 
     104 
     105It is often useful to be able to link to objects on your server that have no built-in 
     106Trac linking mechanism, such as static resources, a `/register` page, etc. This 
     107can be achieved by simply using either an absolute path from the server root,  
     108or a relative link from the URL of the current page: 
     109 
     110{{{ 
     111[../newticket newticket] 
     112[/ home] 
     113}}} 
     114 
     115Display: [../newticket newticket] [/ home] 
     116 
     117== Quoting space in TracLinks == 
     118 
     119Immediately after a TracLinks prefix, targets containing space characters should 
     120be enclosed in a pair of quotes or double quotes. 
     121Examples: 
     122 * !wiki:"The whitespace convention" 
     123 * !attachment:'the file.txt' or 
     124 * !attachment:"the file.txt"  
     125 * !attachment:"ticket:123:the file.txt"  
     126 
     127== Where to use TracLinks == 
     128You can use TracLinks in: 
     129 
     130 * Source code (Subversion) commit messages 
     131 * Wiki pages 
     132 * Full descriptions for tickets, reports and milestones 
     133 
     134and any other text fields explicitly marked as supporting WikiFormatting. 
     135 
     136== Escaping Links == 
     137 
     138To prevent parsing of a !TracLink, you can escape it by preceding it with a '!' (exclamation mark). 
     139{{{ 
     140 !NoLinkHere. 
     141 ![42] is not a link either. 
     142}}} 
     143 
     144Display: 
     145 !NoLinkHere. 
     146 ![42] is not a link either.
