    1 = Trac リンク =
    2 TracLinks は Trac の基礎となる機能です。というのも、 TracLinks によってシステムのエントリ間 - チケット、レポート、チェンジセット、Wikiページ、マイルストーン、ソースファイルなど - で簡単にハイパーリンクすることができるからです。
    3 
    4 TracLinks は通常、 '''type:id''' (''id'' はコンポーネントの
    5 番号や名前、パス) の形式で記述しますが、よく使われるコンポーネントについては、
    6 下の例のように表記を省略することもできます。
    7 
    8 例:
    9  * チケット: '''!#1''' or '''!ticket:1'''
    10  * チケットのコメント: '''!comment:ticket:1:2'''
    11  * レポート: '''!{1}''' or '''!report:1'''
    12  * チェンジセット: '''!r1''', '''![1]''', '''!changeset:1''' or (restricted) '''![1/trunk]''', '''!changeset:1/trunk'''
    13  * リビジョンログ: '''!r1:3''', '''![1:3]''' or '''!log:@1:3''', '''!log:trunk@1:3'''
    14  * Diffs ([http://trac.edgewall.org/milestone/0.10 0.10] 以降): '''!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 ページ: '''CamelCase''' or '''!wiki:CamelCase'''
    16  * マイルストーン: '''!milestone:1.0'''
    17  * 添付ファイル: '''!attachment:ticket:944:attachment.1073.diff'''
    18  * ファイル: '''!source:trunk/COPYING'''
    19  * あるリビジョンのファイル: '''!source:/trunk/COPYING#200'''
    20  * あるリビジョンのファイルのある行数: '''!source:/trunk/COPYING@200#L25'''
    21 表示:
    22  * チケット: #1 or ticket:1
    23  * チケットのコメント: comment:ticket:1:2
    24  * レポート: {1} or report:1
    25  * チェンジセット: r1, [1], changeset:1, or (restricted) [1/trunk], changeset:1/trunk
    26  * リビジョンログ: r1:3, [1:3] or log:@1:3, log:trunk@1:3
    27  * Diffs ([http://trac.edgewall.org/milestone/0.10 0.10] 以降): 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 ページ: CamelCase or wiki:CamelCase
    29  * マイルストーン: milestone:1.0
    30  * 添付ファイル: attachment:ticket:944:attachment.1073.diff
    31  * ファイル: source:trunk/COPYING
    32  * あるリビジョンのファイル: source:/trunk/COPYING#200
    33  * あるリビジョンのファイルのある行数: source:/trunk/COPYING@200#L25
    34 
    35 '''Note:''' wiki:CamelCase の書式が使われることはほとんどありませんが、
    36 ページ名が WikiPageNames のルールに従っていないページ (一文字、
    37 アルファベット以外の文字、etc.) をリンクしたい場合には便利です。
    38 WikiPageNames に Wiki ページ名へのリンクに関する特記事項が書いてあるので見て下さい。
    39 
    40 フル表記の (簡略形でない) Trac リンクでは、次のようにしてリンクタイトルを
    41 カスタマイズすることもできます:
    42 
    43 {{{
    44 [ticket:1 これは1番目のチケットへのリンクです].
    45 }}}
    46 
    47 表示: [ticket:1 これは1番目のチケットへのリンクです].
    48 
    49 タイトルが省略された場合、 ID のみ(コロンの後ろ側)が表示されます。
    50 
    51 {{{
    52 [ticket:1]
    53 }}}
    54 
    55 表示: [ticket:1]
    56 
    57 もし名前空間の一部が省略されていたら、 `wiki` がデフォルトの値です。(''バージョン 0.10 以降''):
    58 
    59 {{{
    60 [SandBox the sandbox]
    61 }}}
    62 
    63 表示: [SandBox the sandbox]
    64 
    65 TracLinks はとてもシンプルなアイディアですが、実際にはとても複雑な情報網になっています。実際、使う分にはとても直感的で簡単ですし、 "リンクの追跡" がプロジェクトでおこったことやなぜある事象が起こったのかを理解するのにとても役に立ちます。
    66 
    67 以下に示すセクションは特定のリンクの種類の詳細について記述しています。 TracLinks の上級者向けの使用方法も同時に記述します。
    68 
    69 == attachment: リンク ==
    70 
    71 添付ファイルへのリンクのシンタックスは次に示すとおりです:
    72  * !attachment:the_file.txt は、現在のオブジェクトに添付されたファイル the_file.txt へのリンクを生成します。
    73  * !attachment:wiki:MyPage:the_file.txt は、 Wiki ページ !MyPage に添付されたファイル the_file.txt へのリンクを生成します。
    74  * !attachment:ticket:753:the_file.txt は、チケット 753 に添付されたファイル the_file.txt へのリンクを生成します。
    75 
    76 == ソースファイルへのリンク ==
    77 
    78 source:/some/path 形式のリンクは、パスがディレクトリを示しているならば
    79 ディレクトリブラウザを開き、それ以外の場合はリビジョンログを表示します。
    80 また、source:/some/file@123 のように表記することで、特定のリビジョンにリンクしたり、
    81 source:/some/file@latest で、最新のリビジョンにリンクすることもできます。
    82 リビジョンを特定している場合、 !source:/some/file@123#L10 の書式で特定の行にリンクすることができます。
    83 
    84 == search: リンクと query: リンク ==
    85 
    86 [wiki:TracSearch#リンク検索 "TracSearch#リンク検索"] と [wiki:TracQuery#TracLinksを使用する "TracQuery#TracLinks を使用する"] 参照。
    87 
    88 == !SubWiki リンク ==
    89 !SubWiki ページへ !SubWiki リンクするには '/' を使います。:
    90 {{{
    91  [wiki:WikiPage/SubWikiPage].
    92 }}}
    93 
    94 == InterWiki リンク ==
    95 
    96 他に、プレフィックスを自由に定義して、他の Web アプリケーションのリソースをポイントさせることができます。プレフィックスと対応する Web アプリケーションの URL の定義は特殊な Wiki ページ、 InterMapTxt ページで定義されます。 他の TracEnvironment へのリンクを作ることもできますが、より柔軟に他の TracEnvironment を指す特別な方法があることを覚えておいてください。
    97 
    98 == InterTrac リンク ==
    99 
    100 上記の TracLinks はすべて一つの TracEnvironment におけるものでした。他の TracEnvironment をあらわすプレフィックスにコロンを付けたものを TracLinks につけると、実際に他の TracEnvironment に存在するリソースを参照します。他の TracEnvironment は登録しなければなりません。詳しくは InterTrac を参照して下さい。
    101 
    102 
    103 == サーバ上の相対リンク  ==
    104 
    105 サーバ上の静的コンテンツや、 `/register` ページ(訳注:一般的なアカウント登録用ページをあらわしています)
    106 など、 Trac リンク機能自体ではリンクを生成できないような同じサーバ上のオブジェクトにリンクすることが出来たら便利なこともあるでしょう。
    107 サーバのルートからの絶対パスか
    108 現在のページの URL からの相対リンクを指定するだけで、そのようなことを実現出来るようになりました:
    109 
    110 {{{
    111 [../newticket newticket]
    112 [/ home]
    113 }}}
    114 
    115 表示: [../newticket newticket] [/ home]
    116 
    117 == Trac リンクで空白文字をエスケープする ==
    118 
    119 TracLinks のプレフィックスの後ろにスペースを含んだターゲットがある場合、
    120 シングルクォーテーションかダブルクォーテーションで囲みます。
    121 例:
     1= Trac Links =
     2[[TracGuideToc]]
     3
     4TracLinks 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.
     5
     6TracLinks are generally of the form '''type:id''' (where ''id'' represents the
     7number, name or path of the item) though some frequently used kinds of items
     8also have short-hand notations.
     9
     10== Where to use TracLinks ==
     11You can use TracLinks in:
     12
     13 * Source code (Subversion) commit messages
     14 * Wiki pages
     15 * Full descriptions for tickets, reports and milestones
     16
     17and any other text fields explicitly marked as supporting WikiFormatting.

     104
     105TracLinks 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.
     106
     107
     108== Advanced use of TracLinks ==
     109
     110=== Relative links ===
     111
     112To create a link to a [trac:SubWiki SubWiki]-page just use a '/':
     113{{{
     114 WikiPage/SubWikiPage or ./SubWikiPage
     115}}}
     116
     117To link from a [trac:SubWiki SubWiki] page to a parent, simply use a '..':
     118{{{
     119  [..] or [[..]]
     120}}}
     121  [..] or [[..]]
     122
     123To link from a [trac:SubWiki SubWiki] page to a [=#sibling sibling] page, use a '../':
     124{{{
     125  [../Sibling see next sibling] or [[../Sibling|see next sibling]]
     126}}}
     127  [../Sibling see next sibling] or [[../Sibling|see next sibling]]
     128
     129But in practice you often won't need to add the `../` prefix to link to a sibling page.
     130For resolving the location of a wiki link, it's the target page closest in the hierarchy
     131to the page where the link is written which will be selected. So for example, within
     132a sub-hierarchy, a sibling page will be targeted in preference to a toplevel page.
     133This makes it easy to copy or move pages to a sub-hierarchy by [[WikiNewPage#renaming|renaming]] without having to adapt the links.
     134
     135In order to link explicitly to a [=#toplevel toplevel] Wiki page,
     136use the `wiki:/` prefix. Be careful **not** to use the `/` prefix alone, as this corresponds to the [#Server-relativelinks] syntax and with such a link you will lack the `/wiki/` part in the resulting URL. A link such as `[../newticket]` will stay in the wiki namespace and therefore link to a sibling page.
     137
     138=== Link anchors ===
     139
     140To create a link to a specific anchor in a page, use '#':
     141{{{
     142 [#Linkanchors Link anchors] or [[#Linkanchors|Link anchors]]
     143}}}
     144  [#Linkanchors Link anchors] or [[#Linkanchors|Link anchors]]
     145
     146Hint: 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.
     147
     148To create a link to the first or last occurrence of a term on a page, use a ''pseudo anchor'' starting with '#/' or '#?':
     149{{{
     150 [#/Milestone first occurrence of Milestone] or
     151 [#?Milestone last occurrence of Milestone]
     152}}}
     153 [#/Milestone first occurrence of Milestone] or
     154 [#?Milestone last occurrence of Milestone]
     155This will also highlight all other matches on the linked page. By default only case sensitive matches are considered. To include case insensitive matches append '/i':
     156{{{
     157 [#/Milestone/i first occurrence of Milestone or milestone] or
     158 [#?Milestone/i last occurrence of Milestone or milestone]
     159}}}
     160 [#/Milestone/i first occurrence of Milestone or milestone] or
     161 [#?Milestone/i last occurrence of Milestone or milestone]
     162
     163''(since Trac 1.0)''
     164
     165Such anchors can be very useful for linking to specific lines in a file in the source browser:
     166{{{
     167 [trac:source:tags/trac-0.12/trac/wiki/api.py#L127 Line 127] or
     168 [trac:source:tags/trac-0.12/trac/ticket/roadmap.py#L47 Line 47]
     169}}}
     170 [trac:source:tags/trac-0.12/trac/wiki/api.py#L127 Line 127] or
     171 [trac:source:tags/trac-0.12/trac/ticket/roadmap.py#L47 Line 47]
     172(Hint: The line numbers displayed in the source browser are links to anchors on the respective lines.)
     173
     174Since such links become outdated when the file changes, it can be useful to link using a '#/' pseudo anchor instead:
     175{{{
     176 [trac:source:trunk/trac/wiki/api.py#/IWikiSyntaxProvider IWikiSyntaxProvider] or
     177 [trac:source:trunk/trac/env.py#/ISystemInfoProvider ISystemInfoProvider]
     178}}}
     179 [trac:source:trunk/trac/wiki/api.py#/IWikiSyntaxProvider IWikiSyntaxProvider] or
     180 [trac:source:trunk/trac/env.py#/ISystemInfoProvider ISystemInfoProvider]
     181
     182=== InterWiki links ===
     183
     184Other 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.
     185
     186=== InterTrac links ===
     187
     188This can be seen as a kind of InterWiki link specialized for targeting other Trac projects.
     189
     190Any 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.
     191
     192A 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].
     193See InterTrac for the complete details.
     194
     195=== Server-relative links ===
     196
     197It is often useful to be able to link to objects in your project that
     198have no built-in Trac linking mechanism, such as static resources, `newticket`,
     199a shared `/register` page on the server, etc.
     200
     201To link to resources inside the project, use either an absolute path from the project root,
     202or a relative link from the URL of the current page (''Changed in 0.11''):
     203
     204{{{
     205[/newticket Create a new ticket] or [[//newticket|Create a new ticket]]
     206[/ home] or [[/|home]]
     207}}}
     208
     209Display: [/newticket Create a new ticket] or [[//newticket|Create a new ticket]]
     210[/ home] or [[/|home]]
     211
     212To link to another location on the server (possibly outside the project but on the same host), use the `//` prefix (''Changed in 0.11''):
     213
     214{{{
     215[//register Register Here] or [[//register|Register Here]]
     216}}}
     217
     218Display: [//register Register Here] or [[//register|Register Here]]
     219
     220=== Quoting space in TracLinks ===
     221
     222Immediately after a TracLinks prefix, targets containing space characters should
     223be enclosed in a pair of quotes or double quotes.
     224Examples:
    122225 * !wiki:"The whitespace convention"
    123  * !attachment:'the file.txt' もしくは
     226 * !attachment:'the file.txt' or
    124227 * !attachment:"the file.txt"
    125  * !attachment:"ticket:123:the file.txt"
    126 
    127 == TracLinks が使えるところ ==
    128 TracLinks が使えるのは:
    129 
    130  * ソースコード (Subverison) のコミットメッセージ
    131  * Wikiページ
    132  * チケット、レポート、マイルストーンでの説明記述箇所
    133 
    134 その他、 WikiFormatting を利用可能なことが明示されているすべてのテキストフィールド。
    135 
    136 == リンクの無効化 ==
    137 
    138 !TracLinks を無効化するには、先頭に '!' (エクスクラメーションマーク)を付けます。
     228 * !attachment:"the file.txt:ticket:123"
     229
     230Note that by using [trac:WikiCreole] style links, it's quite natural to write links containing spaces:
     231 * ![[The whitespace convention]]
     232 * ![[attachment:the file.txt]]
     233
     234=== Escaping Links ===
     235
     236To prevent parsing of a !TracLink, you can escape it by preceding it with a '!' (exclamation mark).
    139237{{{
    140238 !NoLinkHere.
     
    142240}}}
    143241
    144 表示:
     242Display:
    145243 !NoLinkHere.
    146244 ![42] is not a link either.
     245
     246
     247=== Parameterized Trac links ===
     248
     249Many 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.
     250
     251Trac links can support an arbitrary set of parameters, written in the same way as they would be for the corresponding URL. Some examples:
     252 - `wiki:WikiStart?format=txt`
     253 - `ticket:1?version=1`
     254 - `[/newticket?component=module1 create a ticket for module1]`
     255 - `[/newticket?summary=Add+short+description+here create a ticket with URL with spaces]`
     256
     257
     258== TracLinks Reference ==
     259The following sections describe the individual link types in detail, as well as notes on advanced usage of links.
     260
     261=== attachment: links ===
     262
     263The link syntax for attachments is as follows:
     264 * !attachment:the_file.txt creates a link to the attachment the_file.txt of the current object
     265 * !attachment:the_file.txt:wiki:MyPage creates a link to the attachment the_file.txt of the !MyPage wiki page
     266 * !attachment:the_file.txt:ticket:753 creates a link to the attachment the_file.txt of the ticket 753
     267
     268Note that the older way, putting the filename at the end, is still supported: !attachment:ticket:753:the_file.txt.
     269
     270If 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:`.
     271
     272This 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.

     274See also [#export:links].
     275
     276=== comment: links ===
     277
     278When you're inside a given ticket, you can simply write e.g. !comment:3 to link to the third change comment.
     279It is possible to link to a comment of a specific ticket from anywhere using one of the following syntax:
     280 - `comment:3:ticket:123`
     281 - `ticket:123#comment:3` (note that you can't write `#123#!comment:3`!)
     282It is also possible to link to the ticket's description using one of the following syntax:
     283 - `comment:description` (within the ticket)
     284 - `comment:description:ticket:123`
     285 - `ticket:123#comment:description`
     286
     287=== htdocs: links ===
     288
     289Use `htdocs:path/to/file` to reference files in the `htdocs` directory of the Trac environment, the [TracEnvironment#DirectoryStructure web resource directory].
     290
     291=== query: links ===
     292
     293See TracQuery#UsingTracLinks and [#ticket:links].
     294
     295=== search: links ===
     296
     297See TracSearch#SearchLinks
     298
     299=== ticket: links ===
     300 ''alias:'' `bug:`
     301
     302Besides 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.
     303
     304Example:
     305 - `ticket:5000-6000`
     306 - `ticket:1,150`
     307
     308=== timeline: links ===
     309
     310Links 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 if you don't want to compute the UTC time, you can specify a local time followed by your timezone offset relative to UTC.
     311
     312Examples:
     313 - `timeline:2008-01-29`
     314 - `timeline:2008-01-29T15:48`
     315 - `timeline:2008-01-29T15:48Z`
     316 - `timeline:2008-01-29T16:48+01`
     317 - `timeline:2008-01-29T16:48+0100`
     318 - `timeline:2008-01-29T16:48+01:00`
     319
     320=== wiki: links ===
     321
     322See WikiPageNames and [#QuotingspaceinTracLinks quoting space in TracLinks] above. It is possible to create a link to a specific page revision using the syntax WikiStart@1.
     323
     324=== Version Control related links ===
     325
     326It 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).
     327
     328For 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'`.
     329
     330==== source: links ====
     331 ''aliases:'' `browser:`, `repos:`
     332
     333The default behavior for a `source:/some/path link` is to open the browser in that directory directory
     334if the path points to a directory or to show the latest content of the file.
     335
     336It's also possible to link directly to a specific revision of a file like this:
     337 - `source:/some/file@123` - link to the file's revision 123
     338 - `source:/some/file@head` - link explicitly to the latest revision of the file
     339
     340If the revision is specified, one can even link to a specific line number:
     341 - `source:/some/file@123#L10`
     342 - `source:/tag/0.10@head#L10`
     343
     344Finally, one can also highlight an arbitrary set of lines:
     345 - `source:/some/file@123:10-20,100,103#L99` - highlight lines 10 to 20, and lines 100 and 103, and target line 99
     346 - or without version number (the `@` is still needed): `source:/some/file@:10-20,100,103#L99`. Version can be omitted when the path is pointing to a source file that will no longer change (like `source:/tags/...`), otherwise it's better to specify which lines of //which version// of the file you're talking about
     347
     348Note 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)''
     349
     350==== export: links ====
     351
     352To 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:
     353 * `export:/some/file` - get the HEAD revision of the specified file
     354 * `export:123:/some/file` - get revision 123 of the specified file
     355 * `export:/some/file@123` - get revision 123 of the specified file
     356
     357This 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.
     358
     359If 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`).
     360
     361==== log: links ====
     362
     363The `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.
     364 - `log:/` - the latest revisions starting at the root of the repository
     365 - `log:/trunk/tools` - the latest revisions in `trunk/tools`
     366 - `log:/trunk/tools@10000` - the revisions in `trunk/tools` starting from  revision 10000
     367 - `log:@20788,20791:20795` - list revision 20788 and the revisions from 20791 to 20795
     368 - `log:/trunk/tools@20788,20791:20795` - list revision 20788 and the revisions from 20791 to 20795 which affect the given path
     369
     370There are short forms for revision ranges as well:
     371 - `[20788,20791:20795]`
     372 - `[20788,20791:20795/trunk/tools]`
     373 - `r20791:20795` (but not `r20788,20791:20795` nor `r20791:20795/trunk`)
     374
     375Finally, note that in all of the above, a revision range can be written either as `x:y` or `x-y`.
     376
     377In 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]`.
