     5Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a flexible and powerful whole.
     6
     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.

     244== Font Styles
     245
     246The Trac wiki supports the following font styles:
     247||= Wiki Markup =||= Display =||
     248{{{#!td
     249  {{{
     250   * '''bold''',
     251     ''' triple quotes !'''
     252     can be bold too if prefixed by ! ''',
     253   * ''italic''
     254   * '''''bold italic''''' or ''italic and
     255     ''' italic bold ''' ''
     256   * __underline__
     257   * {{{monospace}}} or `monospace`
     258     (hence `{{{` or {{{`}}} quoting)
     259   * ~~strike-through~~
     260   * ^superscript^
     261   * ,,subscript,,
     262   * **also bold**, //italic as well//,
     263     and **'' bold italic **'' //(since 0.12)//
     264   * [[span(style=color: #FF0000, a red text )]]
     265  }}}
     266}}}
     267{{{#!td
     268 * '''bold''',
     269   ''' triple quotes !'''
     270   can be bold too if prefixed by ! ''',
     271 * ''italic''
     272 * '''''bold italic''''' or ''italic and
     273   ''' italic bold ''' ''
     274 * __underline__
     275 * {{{monospace}}} or `monospace`
     276   (hence `{{{` or {{{`}}} quoting)
     277 * ~~strike-through~~
     278 * ^superscript^
     279 * ,,subscript,,
     280 * **also bold**, //italic as well//,
     281   and **'' bold italic **'' //(since 0.12)//
     282 * [[span(style=color: #FF0000, a red text )]]
     283}}}
     284
     285Notes:
     286 * `{{{...}}}` 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.
     287 * {{{ ! }}} 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
     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.
     300
     301||= Wiki Markup =||= Display =||
     302{{{#!td
     303  {{{
     304  = Heading =
     305  == Subheading
     306  === About ''this'' ===
     307  === Explicit id === #using-explicit-id-in-heading
     308  == Subheading #sub2
     309}}}
     310}}}
     311{{{#!td style="padding: 1em;"
     312  {{{
     313  #!div
     314  = Heading =
     315  == Subheading
     316  === About ''this'' ===
     317  === Explicit id === #using-explicit-id-in-heading
     318  == Subheading #sub2
     319  }}}
     320}}}
     321
     322== Paragraphs
     323
     324A new text paragraph is created whenever two blocks of text are separated by one or more empty lines.
     325
     326A forced line break can also be inserted, using:
     327||= Wiki Markup =||= Display =||
     328{{{#!td
     329  {{{
     330  Line 1[[BR]]Line 2
     331  }}}
     332  {{{
     333  Paragraph
     334  one
     335
     336  Paragraph
     337  two
     338  }}}
     339}}}
     340{{{#!td
     341  Line 1[[BR]]Line 2
     342
     343  Paragraph
     344  one
     345
     346  Paragraph
     347  two
     348}}}
     349
     350== Lists
     351
     352The wiki supports both ordered/numbered and unordered lists.
     353
     354Example:
     355||= Wiki Markup =||= Display =||
     356{{{#!td

     363     * Item 1.2
     364   * Item 2
     365  - items can start at the beginning of a line
     366    and they can span multiple lines
     367    - be careful though to continue the line
     368    with the appropriate indentation, otherwise
     369  that will start a new paragraph...
     370 
     371   1. Item 1
     372     a. Item 1.a
     373     a. Item 1.b

     375        i. Item 1.b.ii
     376   1. Item 2
     377  And numbered lists can also be restarted

     387      * Item 1.1.3
     388   * Item 1.2
     389 * Item 2

     402And numbered lists can also be restarted with an explicit number:
     403 3. Item 3
     404}}}
     405
     406== Definition Lists
     407
     408The wiki also supports definition lists.
     409
     410||= Wiki Markup =||= Display =||

     426}}}
     427
     428Note that you need a space in front of the defined term.
     429
     430== Preformatted Text
     431
     432Block containing preformatted text are suitable for source code snippets, notes and examples. Use three ''curly braces'' wrapped around the text to define a block quote. The curly braces need to be on a separate line.
     433 
     434||= Wiki Markup =||= Display =||
     435{{{#!td
     436  {{{
     437  {{{

     444  {{{
     445  def HelloWorld():
     446      print '''Hello World'''
     447  }}}
     448}}}
     449
     450Note that this kind of block is also used for selecting lines that should be processed through WikiProcessors.
     451
     452== Blockquotes
     453
     454In order to mark a paragraph as blockquote, indent that paragraph with two spaces.
     455

     466}}}
     467
     468== Discussion Citations
     469
     470To delineate a citation in an ongoing discussion thread, such as the ticket comment area, email-like citation marks (">", ">>", etc.) may be used. 
     471
     472||= Wiki Markup =||= Display =||
     473{{{#!td
     474  {{{

     486}}}
     487
     488== Tables
     489=== Simple Tables
     490
     491Simple tables can be created like this:
     492||= Wiki Markup =||= Display =||
     493{{{#!td
     494  {{{
     495  ||Cell 1||Cell 2||Cell 3||

     498}}}
     499{{{#!td style="padding: 2em;"
     500||Cell 1||Cell 2||Cell 3||
     501||Cell 4||Cell 5||Cell 6||
     502}}}
     503
     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  {{{

     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] || \
     568  || this is column 2 [http://trac.edgewall.org/roadmap the road ahead] || \

     570  }}}
     571}}}
     572|-------------

     578}}}
     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 =||
     589{{{#!td
     590  {{{
     591  TitleIndex, http://www.edgewall.com/, !NotAlink
     592  }}}
     593}}}
     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.
     600
     601||= Wiki Markup =||= Display =||
     602{{{#!td

     615}}}
     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  {{{
     621   * [[http://www.edgewall.com|Edgewall Software]]

     624   * [[wiki:TitleIndex]]

     635   * [[ISO9000]]
     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
     642
     643Wiki 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:
     644
     645||= Wiki Markup =||= Display =||
     646{{{#!td
     647  {{{
     648   * Tickets: #1 or ticket:1
     649   * Reports: {1} or report:1
     650   * Changesets: r1, [1] or changeset:1
     651   * ...
     652   * targeting other Trac instances,
     653     so called InterTrac links:
     654     - Tickets: #Trac1 or Trac:ticket:1
     655     - Changesets: [Trac1] or Trac:changeset:1
     656  }}}
     657}}}
     658{{{#!td
     659 * Tickets: #1 or ticket:1
     660 * Reports: {1} or report:1
     661 * Changesets: r1, [1] or changeset:1
     662 * ...
     663 * targeting other Trac instances,
     664   so called InterTrac links:
     665   - Tickets: #Trac1 or Trac:ticket:1
     666   - Changesets: [Trac1] or Trac:changeset:1
     667}}}
     668
     669There are many more flavors of Trac links, see TracLinks for more in-depth information and a reference for all the default link resolvers.
     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
     675{{{
     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  {{{
     698  [#point2 jump to the second point]
     699
     700  ...
     701
     702  Point2:  [=#point2] Jump here
     703  }}}
     704}}}
     705{{{#!td
     706  [#point2 jump to the second point]
     707
     708  ...
     709
     710  Point2:  [=#point2] Jump here
     711}}}
     712
     713For more complex anchors (eg when a custom title is wanted), you can use the Span macro: `[[span(id=point2, class=wikianchor, title=Point 2, ^(2)^)]]`.
     714
     715== Escaping Links, WikiPageNames and other Markup == #Escaping
     716
     717You may avoid making hyperlinks out of TracLinks by preceding an expression with a single exclamation mark ('!').
     718
     719||= Wiki Markup =||= Display =||
     720{{{#!td
     721  {{{
     722   !NoHyperLink
     723   !#42 is not a link
     724  }}}
     725  {{{
     726Various forms of escaping for list markup:
     727 ^^- escaped minus sign \\
     728 ^^1. escaped number  \\
     729 ^^* escaped asterisk sign
     730  }}}
     731}}}
     732{{{#!td

     737 ^^- escaped minus sign \\
     738 ^^1. escaped number  \\
     739 ^^* escaped asterisk sign
     740}}}
     741
     742== Images
     743
     744Urls ending with `.png`, `.gif` or `.jpg` are no longer automatically interpreted as image links, and converted to `<img>` tags.
     745
     746You 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)]]`.
     747
     748In addition to the current page, it is possible to refer to other resources:
     749 * `[[Image(wiki:WikiFormatting:picture.gif)]]` (referring to attachment on another page)
     750 * `[[Image(ticket:1:picture.gif)]]` (file attached to a ticket)
     751 * `[[Image(htdocs:picture.gif)]]` (referring to a file inside the [TracEnvironment environment] `htdocs` directory)
     752 * `[[Image(source:/trunk/trac/htdocs/trac_logo_mini.png)]]` (a file in repository)
     753
     754||= Wiki Markup =||= Display =||
     755{{{#!td
     756  {{{
     757  [[Image(htdocs:../common/trac_logo_mini.png)]]
     758  }}}
     759}}}
     760{{{#!td
     761[[Image(htdocs:../common/trac_logo_mini.png)]]
     762}}}
     763
     764See WikiMacros for further documentation on the `[[Image()]]` macro, which has several useful options (`title=`, `link=`, etc.)
     765
     766== Macros
     767
     768Macros are ''custom functions'' to insert dynamic content in a page.
     769

     781
     782The detailed help for a specific macro can also be obtained more directly by appending a "?" to the macro name.

     793
     794== Processors
     795
     796Trac supports alternative markup formats using WikiProcessors. For example, processors are used to write pages in
     797[wiki:WikiRestructuredText reStructuredText] or [wiki:WikiHtml HTML].
