            |  | 3 | Trac supports a convenient way to refer to resources of other Trac servers using Wiki markup. An !InterTrac link can be seen as a scoped [TracLinks TracLink]. It is used for referring to a Trac resource located in another Trac environment. | 
          
            |  | 4 |  | 
          
            |  | 5 | == Link Syntax | 
          
            |  | 6 |  | 
          
            |  | 7 | Simply use the name of the other Trac environment as a prefix, followed by a colon, ending with the resource located in the other environment: | 
          
            |  | 8 |  | 
          
            |  | 9 | {{{ | 
          
            |  | 10 | <target_environment>:<TracLinks> | 
          
            |  | 11 | }}} | 
          
            |  | 12 |  | 
          
            |  | 13 | The other resource is specified using a regular !TracLink, of any flavor. | 
          
            |  | 14 |  | 
          
            |  | 15 | That target environment name is either the real name of the environment or an alias. | 
          
            |  | 16 | The aliases are defined in the `trac.ini` file, see below. | 
          
            |  | 17 | The prefix is case insensitive. | 
          
            |  | 18 |  | 
          
            |  | 19 | If the InterTrac link is enclosed in square brackets, like `[th:WikiExtrasPlugin]`, the InterTrac prefix is removed in the displayed link like a normal link resolver would be. For example, the above would be displayed as `WikiExtrasPlugin`. | 
          
            |  | 20 |  | 
          
            |  | 21 | For convenience, there is also an alternate short-hand form, where an alias can be used as an immediate prefix for the identifier of a ticket, changeset or report, eg `#T234`, `[T1508]`, `[trac 1508]`. | 
          
            |  | 22 |  | 
          
            |  | 23 | == Examples | 
          
            |  | 24 |  | 
          
            |  | 25 | The only prefix defined by default is `trac`, which points to trac.edgewall.org. Additional prefixes can be specified in the [TracIni#intertrac-section intertrac] section of TracIni. For example: | 
          
            |  | 26 |  | 
          
            |  | 27 | {{{#!ini | 
          
            |  | 28 | [intertrac] | 
          
            |  | 29 | # -- Example of setting up an alias: | 
          
            |  | 30 | t = trac | 
          
            |  | 31 |  | 
          
            |  | 32 | # -- Link to an external Trac: | 
          
            |  | 33 | genshi.title = Edgewall's Trac for Genshi | 
          
            |  | 34 | genshi.url = http://genshi.edgewall.org | 
          
            |  | 35 | }}} | 
          
            |  | 36 |  | 
          
            |  | 37 | The `.url` is mandatory and is used for locating the other Trac. | 
          
            |  | 38 | It can be a relative URL when the Trac environment is located on the same server. | 
          
            |  | 39 |  | 
          
            |  | 40 | The `.title` information is used in a tooltip, ie when hovering the cursor over an InterTrac link. | 
          
            |  | 41 |  | 
          
            |  | 42 | Now, given the above configuration, one could create the following links: | 
          
            |  | 43 | * to this InterTrac page: | 
          
            |  | 44 | * `trac:wiki:InterTrac` trac:wiki:InterTrac | 
          
            |  | 45 | * `t:wiki:InterTrac` t:wiki:InterTrac | 
          
            |  | 46 | * `genshi:InterTrac` genshi:InterTrac | 
          
            |  | 47 | * Keys are case insensitive: `T:wiki:InterTrac` T:wiki:InterTrac | 
          
            |  | 48 | * to the ticket #234: | 
          
            |  | 49 | * `trac:ticket:234` trac:ticket:234 | 
          
            |  | 50 | * `trac:#234` trac:#234 | 
          
            |  | 51 | * `genshi:#234` genshi:#234 | 
          
            |  | 52 | * `#T234` #T234 | 
          
            |  | 53 | * to the changeset [1912]: | 
          
            |  | 54 | * `trac:changeset:1912` trac:changeset:1912 | 
          
            |  | 55 | * `[T1912]` [T1912] | 
          
            |  | 56 | * to the log range [3300:3330]: | 
          
            |  | 57 | * `trac:log:@3300:3330` trac:log:@3300:3330 | 
          
            |  | 58 | * `[trac 3300:3330]` [trac 3300:3330] | 
          
            |  | 59 | * finally, to link to the start page of a remote trac, simply use its prefix followed by ':', inside an explicit link. Example: `[th: Trac Hacks]` (note that the ''remote'' Trac has to run Trac >= 0.11 for this to work'') | 
          
            |  | 60 |  | 
          
            |  | 61 | The generic form `intertrac_prefix:module:id` is translated to the corresponding URL `<remote>/module/id`. Shorthand links are specific to some modules (e.g. !#T234 is processed by the ticket module). For the rest (`intertrac_prefix:something`), we rely on the [TracSearch#quickjump quick jump] facility of the remote Trac. |
