    45Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a flexible and powerful whole.
    56
    6 Trac 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

    10 This page demonstrates the formatting syntax available anywhere WikiFormatting is allowed.

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

     283}}}
    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.
    40 
    41 == Headings ==
    42 
    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.
     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
     292== Headings
     293
     294You can create heading by starting a line with one up to six ''equal'' characters ("=") followed by a single space and the headline text.
     295
     296[=#hn]
     297The headline text can be followed by the same number of "=" characters, but this is not mandatory. That is, `=== Section3 ===` is identical to `=== Section3`.
     298
     299Finally, the heading might optionally be followed by an explicit id. If not, an implicit but nevertheless readable id will be generated.

     488== Tables
     489=== Simple Tables
    194490
    195491Simple tables can be created like this:
    196 {{{
     492||= Wiki Markup =||= Display =||
     493{{{#!td
     494  {{{
     495  ||Cell 1||Cell 2||Cell 3||

    201 Display:
    202 ||Cell 1||Cell 2||Cell 3||
    203 ||Cell 4||Cell 5||Cell 6||
    204 
    205 Note that more complex tables can be created using
    206 [wiki:WikiRestructuredText#BiggerReSTExample reStructuredText].
    207 
    208 
    209 == Links ==
    210 
    211 Hyperlinks are automatically created for WikiPageNames and URLs. !WikiPageLinks can be disabled by prepending an exclamation mark "!" character, such as {{{!WikiPageLink}}}.
    212 
    213 Example:
    214 {{{
    215  TitleIndex, http://www.edgewall.com/, !NotAlink
    216 }}}
    217 
    218 Display:
    219  TitleIndex, http://www.edgewall.com/, !NotAlink
    220 
    221 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.
    222 
    223 Example:
    224 {{{
    225  * [http://www.edgewall.com/ Edgewall Software]
    226  * [wiki:TitleIndex Title Index]
    227  * [wiki:ISO9000]
    228 }}}
    229 
    230 Display:
    231  * [http://www.edgewall.com/ Edgewall Software]
    232  * [wiki:TitleIndex Title Index]
    233  * [wiki:ISO9000]
    234 
    235 == Trac Links ==
     504Cell headings can be specified by wrapping the content in a pair of '=' characters.
     505Note that the '=' characters have to stick to the cell separators, like this:
     506||= Wiki Markup =||= Display =||
     507{{{#!td
     508  {{{
     509  ||        ||= stable =||= latest =||
     510  ||= 0.10 =||  0.10.5  || 0.10.6dev||
     511  ||= 0.11 =||  0.11.6  || 0.11.7dev||
     512  }}}
     513}}}
     514{{{#!td style="padding: 2em;"
     515||        ||= stable =||= latest =||
     516||= 0.10 =||  0.10.5  || 0.10.6dev||
     517||= 0.11 =||  0.11.6  || 0.11.7dev||
     518}}}
     519
     520Finally, specifying an empty cell means that the next non empty cell will span the empty cells. For example:
     521||= Wiki Markup =||= Display =||
     522{{{#!td
     523  {{{
     524  || 1 || 2 || 3 ||
     525  |||| 1-2 || 3 ||
     526  || 1 |||| 2-3 ||
     527  |||||| 1-2-3 ||
     528  }}}
     529}}}
     530{{{#!td style="padding: 2em;"
     531|| 1 || 2 || 3 ||
     532|||| 1-2 || 3 ||
     533|| 1 |||| 2-3 ||
     534|||||| 1-2-3 ||
     535}}}
     536
     537Note 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:
     538||= Wiki Markup =||= Display =||
     539{{{#!td
     540  {{{
     541  ||=Text =||= Numbers =||
     542  ||left align    ||        1.0||
     543  ||  center      ||        4.5||
     544  ||      right align||     4.5||
     545  || default alignment ||   2.5||
     546  ||default||         2.5||
     547  ||  default ||      2.5||
     548  || default ||       2.5||
     549  }}}
     550}}}
     551{{{#!td style="padding: 2em;"
     552||=Text =||= Numbers =||
     553||left align    ||        1.0||
     554||  center      ||        4.5||
     555||      right align||     4.5||
     556|| default alignment ||   2.5||
     557||default||         2.5||
     558||  default ||      2.5||
     559|| default ||       2.5||
     560}}}
     561
     562If 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.
     563
     564||= Wiki Markup =||
     565{{{#!td
     566  {{{
     567  || this is column 1 [http://trac.edgewall.org/newticket new ticket] || \

     579
     580=== Complex Tables
     581
     582If the possibilities offered by the simple pipe-based markup ('||') for tables described above are not enough for your needs, you can create more elaborate tables by using [#Processors-example-tables WikiProcessor based tables].
     583
     584== Links
     585
     586Hyperlinks are automatically created for WikiPageNames and URLs. !WikiPageLinks can be disabled by prepending an exclamation mark ('!'), such as {{{!WikiPageLink}}}.
     587
     588||= Wiki Markup =||= Display =||

     594{{{#!td
     595TitleIndex, http://www.edgewall.com/, !NotAlink
     596}}}
     597
     598Links can be given a more descriptive title by writing the link followed by a space and a title and all this inside square brackets.
     599If 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.

     616
     617Following 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.
     618
     619{{{#!td
     620  {{{

     636}}}
     637
     638'''Note''': the [trac:WikiCreole] style for links is quick to type and certainly looks familiar as it is the one used on Wikipedia and in many other wikis. Unfortunately it conflicts with the syntax for [#Macros macros].
     639So in the rare case when you need to refer to a page which is named after a macro (typical examples being TitleIndex, InterTrac and InterWiki), by writing `[[TitleIndex]]` you will actually call the macro instead of linking to the page.
     640
     641== Trac Links
    236642
    237643Wiki 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:
    238 {{{
    239  * Tickets: #1 or ticket:1
    240  * Reports: {1} or report:1
    241  * Changesets: r1, [1] or changeset:1

     670
     671== Setting Anchors
     672
     673An 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:
     674
    259675{{{
     676[=#point1]
     677}}}
     678
     679This syntax was chosen to match the format for explicitly naming the header id [#Headings documented above]. For example:
     680{{{
     681== Long title == #title
     682}}}
     683
     684It is also very close to the syntax for the corresponding link to that anchor:
     685{{{
     686[#point1]
     687}}}
     688
     689Optionally, a label can be given to the anchor:
     690{{{
     691[[=#point1 '''Point 1''']]
     692}}}
     693
     694||= Wiki Markup =||= Display =||
     695|----------------------------------
     696{{{#!td
     697  {{{

     711}}}
     712
