| 5 | == Definition == |
| 6 | |
| 7 | An InterWiki link can be used for referring to a Wiki page |
| 8 | located in another Wiki system, and by extension, to any object |
| 9 | located in any other Web application, provided a simple URL |
| 10 | mapping can be done. |
| 11 | |
| 12 | At the extreme, InterWiki prefixes can even be used to simply introduce |
| 13 | links to new protocols, such as `tsvn:` used by TortoiseSvn. |
| 14 | |
| 15 | == Link Syntax == |
| 16 | |
| 17 | {{{ |
| 18 | <target_wiki>(:<identifier>)+ |
| 19 | }}} |
| 20 | |
| 21 | The link is composed by the targeted Wiki (or system) name, |
| 22 | followed by a colon (e.g. `MeatBall:`), |
| 23 | followed by a page specification in the target. |
| 24 | Note that, as for InterTrac prefixes, '''InterWiki prefixes are case insensitive'''. |
| 25 | |
| 26 | The target Wiki URL is looked up in the InterMapTxt wiki page, |
| 27 | modelled after MeatBall:InterMapTxt. |
| 28 | |
| 29 | In addition to traditional InterWiki links, where the target |
| 30 | is simply ''appended'' to the URL, |
| 31 | Trac supports parametric InterWiki URLs: |
| 32 | identifiers `$1`, `$2`, ... in the URL |
| 33 | will be replaced by corresponding arguments. |
| 34 | The argument list is formed by splitting the page identifier |
| 35 | using the ":" separator. |
| 36 | |
| 37 | == Examples == |
| 38 | |
| 39 | If the following is an excerpt of the InterMapTxt page: |
| 40 | |
| 41 | {{{ |
| 42 | = InterMapTxt = |
| 43 | == This is the place for defining InterWiki prefixes == |
| 44 | |
| 45 | Currently active prefixes: [[InterWiki]] |
| 46 | |
| 47 | This page is modelled after the MeatBall:InterMapTxt page. |
| 48 | In addition, an optional comment is allowed after the mapping. |
