    66Trac has a built in small and powerful wiki rendering engine. This wiki engine implements an ever growing subset of the commands from other popular Wikis,
    7 especially [http://moinmoin.wikiwikiweb.de/ MoinMoin].
    8 
    9 
    10 This page demonstrates the formatting syntax available anywhere WikiFormatting is allowed.
     7especially [http://moinmo.in/ MoinMoin] and [trac:WikiCreole].
     8
     9
     10This page will give you an in-depth explanation of the wiki markup available anywhere WikiFormatting is allowed.
     11
     12The ''Cheat sheet'' below gives you a quick overview for the most common syntax, each link in the ''Category'' column will lead you to the more detailed explanation later in this page.
     13
     14A few other wiki pages present the advanced features of the Trac wiki markup in more depth:
     15 - TracLinks covers all the possible ways to refer precisely to any Trac resource or parts thereof,
     16 - WikiPageNames talks about the various names a wiki page can take, CamelCase or not
     17 - WikiMacros lists the macros available for generating dynamic content,
     18 - WikiProcessors and WikiHtml details how parts of the wiki text can be processed in special ways

    36284
    37285Notes:
    38286 * `{{{...}}}` and {{{`...`}}} commands not only select a monospace font, but also treat their content as verbatim text, meaning that no further wiki processing is done on this text.
    39287 * {{{ ! }}} tells wiki parser to not take the following characters as wiki format, so pay attention to put a space after !, e.g. when ending bold.
     288 * all the font styles marks have to be used in opening/closing pairs,
     289   and they must nest properly (in particular, an `''` italic can't be paired
     290   with a `//` one, and `'''` can't be paired with `**`)
     291
    40292
    41293== Headings ==
    42294
    43 You can create heading by starting a line with one up to five ''equal'' characters ("=")
    44 followed by a single space and the headline text. The line should end with a space
    45 followed by the same number of ''='' characters.
    46 The heading might optionally be followed by an explicit id. If not, an implicit but nevertheless readable id will be generated.
     295You can create heading by starting a line with one up to six ''equal'' characters ("=")
     296followed by a single space and the headline text.
     297
     298[=#hn]
     299The headline text can be followed by the same number of "=" characters, but this is no longer mandatory.
     300
     301Finally, the heading might optionally be followed by an explicit id. If not, an implicit but nevertheless readable id will be generated.

    184492
    185493== Tables ==
    186 
     494=== Simple Tables ===
    187495Simple tables can be created like this:
    188 {{{
     496||= Wiki Markup =||= Display =||
     497{{{#!td
     498  {{{
     499  ||Cell 1||Cell 2||Cell 3||
     500  ||Cell 4||Cell 5||Cell 6||
     501  }}}
     502}}}
     503{{{#!td style="padding: 2em;"
    189504||Cell 1||Cell 2||Cell 3||
    190505||Cell 4||Cell 5||Cell 6||
    191506}}}
    192507
    193 Display:
    194 ||Cell 1||Cell 2||Cell 3||
    195 ||Cell 4||Cell 5||Cell 6||
    196 
    197 Note that more complex tables can be created using
    198 [wiki:WikiRestructuredText#BiggerReSTExample reStructuredText].
     508Cell headings can be specified by wrapping the content in a pair of '=' characters.
     509Note that the '=' characters have to stick to the cell separators, like this:
     510||= Wiki Markup =||= Display =||
     511{{{#!td
     512  {{{
     513  ||        ||= stable =||= latest =||
     514  ||= 0.10 =||  0.10.5  || 0.10.6dev||
     515  ||= 0.11 =||  0.11.6  || 0.11.7dev||
     516  }}}
     517}}}
     518{{{#!td style="padding: 2em;"
     519||        ||= stable =||= latest =||
     520||= 0.10 =||  0.10.5  || 0.10.6dev||
     521||= 0.11 =||  0.11.6  || 0.11.7dev||
     522}}}
     523
     524Finally, specifying an empty cell means that the next non empty cell will span the empty cells. For example:
     525||= Wiki Markup =||= Display =||
     526{{{#!td
     527  {{{
     528  || 1 || 2 || 3 ||
     529  |||| 1-2 || 3 ||
     530  || 1 |||| 2-3 ||
     531  |||||| 1-2-3 ||
     532  }}}
     533}}}
     534{{{#!td style="padding: 2em;"
     535|| 1 || 2 || 3 ||
     536|||| 1-2 || 3 ||
     537|| 1 |||| 2-3 ||
     538|||||| 1-2-3 ||
     539}}}
     540
     541Note that if the content of a cell "sticks" to one side of the cell and only one, then the text will be aligned on that side. Example:
     542||= Wiki Markup =||= Display =||
     543{{{#!td
     544  {{{
     545  ||=Text =||= Numbers =||
     546  ||left align    ||        1.0||
     547  ||  center      ||        4.5||
     548  ||      right align||     4.5||
     549  || default alignment ||   2.5||
     550  ||default||         2.5||
     551  ||  default ||      2.5||
     552  || default ||       2.5||
     553  }}}
     554}}}
     555{{{#!td style="padding: 2em;"
     556||=Text =||= Numbers =||
     557||left align    ||        1.0||
     558||  center      ||        4.5||
     559||      right align||     4.5||
     560|| default alignment ||   2.5||
     561||default||         2.5||
     562||  default ||      2.5||
     563|| default ||       2.5||
     564}}}
     565
     566If contrary to the example above, the cells in your table contain more text, it might be convenient to spread a table row over multiple lines of markup. The `\` character placed at the end of a line after a cell separator tells Trac to not start a new row for the cells on the next line.
     567
     568||= Wiki Markup =||
     569{{{#!td

     583
     584=== Complex Tables ===
     585
     586If the possibilities offered by the simple "pipe"-based markup for tables described above are not enough for your needs, you can create more elaborated tables by using [#Processors-example-tables WikiProcessor based tables].
    199587
    200588
     
    203591Hyperlinks are automatically created for WikiPageNames and URLs. !WikiPageLinks can be disabled by prepending an exclamation mark "!" character, such as {{{!WikiPageLink}}}.
    204592
    205 Example:
    206 {{{
    207  TitleIndex, http://www.edgewall.com/, !NotAlink
    208 }}}
    209 
    210 Display:
    211  TitleIndex, http://www.edgewall.com/, !NotAlink
    212 
    213 Links can be given a more descriptive title by writing the link followed by a space and a title and all this inside square brackets.  If the descriptive title is omitted, then the explicit prefix is discarded, unless the link is an external link. This can be useful for wiki pages not adhering to the WikiPageNames convention.
    214

     621
     622Following the [trac:WikiCreole] trend, the descriptive title can also be specified by writing the link followed by a pipe ('|') and a title and all this inside //double// square brackets.
     623
     624{{{#!td

     642
     643'''Note''': the [trac:WikiCreole] style for links is quick to type and
     644certainly looks familiar as it's the one used on Wikipedia and in many
     645other wikis. Unfortunately it conflicts with the syntax for [#Macros macros].
     646So in the rare case when you need to refer to a page which is named after
     647a macro (typical examples being TitleIndex, InterTrac and InterWiki),
     648by writing `[[TitleIndex]]` you will actually call the macro instead of linking
     649to the page.
     650
     651== Trac Links ==
    229652
    230653Wiki pages can link directly to other parts of the Trac system. Pages can refer to tickets, reports, changesets, milestones, source files and other Wiki pages using the following notations:
    231 {{{
    232  * Tickets: #1 or ticket:1
    233  * Reports: {1} or report:1
    234  * Changesets: r1, [1] or changeset:1

     680
     681
     682== Setting Anchors ==
     683
     684An anchor, or more correctly speaking, an [http://www.w3.org/TR/REC-html40/struct/links.html#h-12.2.1 anchor name] can be added explicitly at any place in the Wiki page, in order to uniquely identify a position in the document:
     685
     686{{{
     687[=#point1]
     688}}}
     689
     690This syntax was chosen to match the format for explicitly naming the header id [#Headings documented above]. For example:
     691{{{
     692== Long title == #title
     693}}}
     694
     695It's also very close to the syntax for the corresponding link to that anchor:
     696{{{
     697[#point1]
     698}}}
     699
     700Optionally, a label can be given to the anchor:
     701{{{
     702[[=#point1 '''Point 1''']]
     703}}}
     704
     705||= Wiki Markup =||= Display =||
     706|----------------------------------
     707{{{#!td
     708  {{{
     709  [#point2 jump to the second point]
     710
     711  ...
     712
     713  Point2:  [=#point2] Jump here
     714  }}}
     715}}}
     716{{{#!td
     717  [#point2 jump to the second point]
     718
     719  ...
     720
     721  Point2:  [=#point2] Jump here
     722}}}
     723
     724For more complex anchors (e.g. when a custom title is wanted), one can use the Span macro, e.g. `[[span(id=point2, class=wikianchor, title=Point 2, ^(2)^)]]`.
     725
     726
     727== Escaping Links, WikiPageNames and other Markup == #Escaping
    248728
    249729You may avoid making hyperlinks out of TracLinks by preceding an expression with a single "!" (exclamation mark).

    261753
    262754== Images ==
     
    264756Urls ending with `.png`, `.gif` or `.jpg` are no longer automatically interpreted as image links, and converted to `<img>` tags.
    265757
    266 You now have to use the ![[Image]] macro (see below).
     758You now have to use the ![[Image]] macro. The simplest way to include an image is to upload it as attachment to the current page, and put the filename in a macro call like `[[Image(picture.gif)]]`.
     759
     760In addition to the current page, it is possible to refer to other resources:
     761 * `[[Image(wiki:WikiFormatting:picture.gif)]]` (referring to attachment on another page)
     762 * `[[Image(ticket:1:picture.gif)]]` (file attached to a ticket)
     763 * `[[Image(htdocs:picture.gif)]]` (referring to a file inside the [TracEnvironment environment] `htdocs` directory)
     764 * `[[Image(source:/trunk/trac/htdocs/trac_logo_mini.png)]]` (a file in repository)
