| 67 | | The following sections describe the individual link types in detail, as well as several notes advanced usage of links. |
| 68 | | |
| 69 | | == attachment: links == |
| 70 | | |
| 71 | | The 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 | | |
| 78 | | The default behavior for a source:/some/path link is to open the directory browser |
| 79 | | if the path points to a directory and otherwise open the log view. |
| 80 | | It's also possible to link directly to a specific revision of a file like this: source:/some/file@123 |
| 81 | | or like this to link to the latest revision: source:/some/file@latest. |
| 82 | | If 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 | | |
| 86 | | See TracSearch#SearchLinks and TracQuery#UsingTracLinks |
| 87 | | |
| 88 | | == !SubWiki links == |
| 89 | | To create a SubWiki link to a SubWiki-page just use a '/': |
| 90 | | {{{ |
| 91 | | [wiki:WikiPage/SubWikiPage]. |
| 92 | | }}} |
| 93 | | |
| 94 | | == InterWiki links == |
| | 82 | |
| | 83 | == Advanced use of TracLinks == |
| | 84 | |
| | 85 | === Relative links === |
| | 86 | |
| | 87 | To create a link to a specific anchor in a page, use '#': |
| | 88 | {{{ |
| | 89 | [#Relativelinks relative links] |
| | 90 | }}} |
| | 91 | Displays: |
| | 92 | [#Relativelinks relative links] |
| | 93 | |
| | 94 | Hint: 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. |
| | 95 | |
| | 96 | To create a link to a [trac:SubWiki SubWiki]-page just use a '/': |
| | 97 | {{{ |
| | 98 | WikiPage/SubWikiPage or ./SubWikiPage |
| | 99 | }}} |
| | 100 | |
| | 101 | To link from a [trac:SubWiki SubWiki] page to a parent, simply use a '..': |
| | 102 | {{{ |
| | 103 | [..] |
| | 104 | }}} |
| | 105 | |
| | 106 | To link from a [trac:SubWiki SubWiki] page to a sibling page, use a '../': |
| | 107 | {{{ |
| | 108 | [../Sibling see next sibling] |
| | 109 | }}} |
| | 110 | |
| | 111 | ''(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 now in 0.11 it will stay in the wiki namespace and link to a sibling page. See [#Server-relativelinks] for the new syntax. |
| | 112 | |
| | 113 | === InterWiki links === |
| 98 | | == InterTrac links == |
| 99 | | |
| 100 | | 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. |
| 101 | | |
| 102 | | |
| 103 | | == Server-relative links == |
| 104 | | |
| 105 | | It is often useful to be able to link to objects on your server that have no built-in |
| 106 | | Trac linking mechanism, such as static resources, a `/register` page, etc. This |
| 107 | | can be achieved by simply using either an absolute path from the server root, |
| 108 | | or a relative link from the URL of the current page: |
| 109 | | |
| 110 | | {{{ |
| 111 | | [../newticket newticket] |
| | 117 | === InterTrac links === |
| | 118 | |
| | 119 | This can be seen as a kind of InterWiki link specialized for targeting other Trac projects. |
| | 120 | |
| | 121 | Any type 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, under its name or an alias. See InterTrac for details. |
| | 122 | |
| | 123 | A distinctive advantage of InterTrac links over InterWiki links is that the shorthand form of Trac links usually have a way to understand the InterTrac prefixes. For example, links to Trac tickets can be written #T234 (if T was set as an alias for Trac), links to Trac changesets can be written [trac 1508]. |
| | 124 | |
| | 125 | === Server-relative links === |
| | 126 | |
| | 127 | It is often useful to be able to link to objects in your project that |
| | 128 | have no built-in Trac linking mechanism, such as static resources, `newticket`, |
| | 129 | a shared `/register` page on the server, etc. |
| | 130 | |
| | 131 | To link to resources inside the project, use either an absolute path from the project root, |
| | 132 | or a relative link from the URL of the current page (''Changed in 0.11''): |
| | 133 | |
| | 134 | {{{ |
| | 135 | [/newticket Create a new ticket] |
| | 171 | |
| | 172 | === Parameterized Trac links === |
| | 173 | |
| | 174 | The Trac links target Trac resources which have generally more than one way to be rendered, according to 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. |
| | 175 | |
| | 176 | Any Trac links can support an arbitrary set of parameters, written in the same way as they would be for the corresponding URL. Some examples: |
| | 177 | - `wiki:WikiStart?format=txt` |
| | 178 | - `ticket:1?version=1` |
| | 179 | - `[/newticket?component=module1 create a ticket for module1]` |
| | 180 | |
| | 181 | |
| | 182 | == TracLinks Reference == |
| | 183 | The following sections describe the individual link types in detail, as well as several notes advanced usage of links. |
| | 184 | |
| | 185 | === attachment: links === |
| | 186 | |
| | 187 | The link syntax for attachments is as follows: |
| | 188 | * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object |
| | 189 | * !attachment:the_file.txt:wiki:MyPage creates a link to the attachment the_file.txt of the !MyPage wiki page |
| | 190 | * !attachment:the_file.txt:ticket:753 creates a link to the attachment the_file.txt of the ticket 753 |
| | 191 | |
| | 192 | Note that the older way, putting the filename at the end, is still supported: !attachment:ticket:753:the_file.txt. |
| | 193 | |
| | 194 | If 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:`. |
| | 195 | |
| | 196 | This 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. |
| | 197 | |
| | 198 | See also [#export:links]. |
| | 199 | |
| | 200 | === comment: links === |
| | 201 | |
| | 202 | When you're inside a given tickets, you can simply write e.g. !comment:3 to link to the third change comment. |
| | 203 | It's also possible to link to a comment of a specific ticket from anywhere using one of the following syntax: |
| | 204 | - !comment:3:ticket:123 |
| | 205 | - !ticket:123#comment:3 (note that you can't write !#123#!comment:3!) |
| | 206 | |
| | 207 | === query: links === |
| | 208 | |
| | 209 | See TracQuery#UsingTracLinks and [#ticket:links]. |
| | 210 | |
| | 211 | === search: links === |
| | 212 | |
| | 213 | See TracSearch#SearchLinks |
| | 214 | |
| | 215 | === ticket: links === |
| | 216 | |
| | 217 | Besides 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. |
| | 218 | |
| | 219 | Example: |
| | 220 | - `ticket:5000-6000` |
| | 221 | - `ticket:1,150` |
| | 222 | |
| | 223 | ''(since Trac 0.11)'' |
| | 224 | |
| | 225 | === timeline: links === |
| | 226 | |
| | 227 | Links 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. |
| | 228 | |
| | 229 | Examples: |
| | 230 | - `timeline:2008-01-29` |
| | 231 | - `timeline:2008-01-29T15:48` |
| | 232 | - `timeline:2008-01-29T16:48Z+01` |
| | 233 | |
| | 234 | ''(since Trac 0.11)'' |
| | 235 | |
| | 236 | === wiki: links === |
| | 237 | |
| | 238 | See WikiPageNames and [#QuotingspaceinTracLinks quoting space in TracLinks] above. |
| | 239 | |
| | 240 | === Version Control related links === |
| | 241 | ==== source: links ==== |
| | 242 | |
| | 243 | The default behavior for a source:/some/path link is to open the directory browser |
| | 244 | if the path points to a directory and otherwise open the log view. |
| | 245 | |
| | 246 | It's also possible to link directly to a specific revision of a file like this: |
| | 247 | - `source:/some/file@123` - link to the file's revision 123 |
| | 248 | - `source:/some/file@head` - link explicitly to the latest revision of the file |
| | 249 | |
| | 250 | If the revision is specified, one can even link to a specific line number: |
| | 251 | - `source:/some/file@123#L10` |
| | 252 | - `source:/tag/0.10@head#L10` |
| | 253 | |
| | 254 | Finally, one can also highlight an arbitrary set of lines: |
| | 255 | - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103. |
| | 256 | ''(since 0.11)'' |
| | 257 | |
| | 258 | ==== export: links ==== |
| | 259 | |
| | 260 | 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: |
| | 261 | * `export:/some/file` - get the HEAD revision of the specified file |
| | 262 | * `export:123:/some/file` - get revision 123 of the specified file |
| | 263 | * `export:/some/file@123` - get revision 123 of the specified file |
| | 264 | |
| | 265 | This 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. |
| | 266 | |
| | 267 | 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`). |
| | 268 | |
| | 269 | ==== log: links ==== |
| | 270 | |
| | 271 | The `log:` links are used to display revision ranges. In its simplest form, it can link to the latest revisions from the specified path, but it can also support displaying an arbitrary set of revisions. |
| | 272 | - `log:/` - the latest revisions starting at the root of the repository |
| | 273 | - `log:/trunk/tools` - the latest revisions in `trunk/tools` |
| | 274 | - `log:/trunk/tools@10000` - the revisions in `trunk/tools` starting from revision 10000 |
| | 275 | - `log:@20788,20791:20795` - list revision 20788 and the 20791 to 20795 revision range |
| | 276 | - `log:/trunk/tools@20788,20791:20795` - list revision 20788 and the revisions from the 20791 to 20795 range which affect the given path |
| | 277 | |
| | 278 | There are short forms for revision ranges as well: |
| | 279 | - `[20788,20791:20795]` |
| | 280 | - `[20788,20791:20795/trunk/tools]` |
| | 281 | - `r20791:20795` (but not `r20788,20791:20795` nor `r20791:20795/trunk`) |
| | 282 | |
| | 283 | Finally, note that in all of the above, a revision range can be written indifferently `x:y` or `x-y`. |
| | 284 | |
