    4 Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a flexible and powerful whole.
    5 
    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 powerful wiki rendering engine that implements a subset of the commands from other popular Wikis, such as [https://moinmo.in/ MoinMoin] and [trac:WikiCreole].
     8
     9The sections below provide an overview for the most common syntax, each link in the ''Category'' column leads you to the more detailed explanation later in this page.
     10
     11The following wiki pages present the advanced features of the Trac wiki markup in more depth:
     12 - TracLinks covers all the possible ways to refer to any Trac resource or parts thereof.
     13 - WikiPageNames covers the various names a wiki page can take, whether in CamelCase or not.
     14 - WikiMacros lists the macros available for generating dynamic content.
     15 - WikiProcessors and WikiHtml details how parts of the wiki text can be processed in special ways.
     16 - [trac:wiki:TracDev/Proposals/AdvancedWikiOperations AdvancedWikiOperations] provides some operations in uncommon or administrative scenarios.

     274 * [[span(style=color: #FF0000, a red text )]]
     275}}}
    36276
    37277Notes:
    38278 * `{{{...}}}` 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.
    39  * {{{ ! }}} 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.
    47 
    48 Example:
    49 {{{
    50 = Heading =
    51 == Subheading ==
    52 === About ''this'' ===
    53 === Explicit id === #using-explicit-id-in-heading
    54 }}}
    55 
    56 Display:
    57 = Heading =
    58 == Subheading ==
    59 === About ''this'' ===
    60 === Explicit id === #using-explicit-id-in-heading
    61 
    62 == Paragraphs ==
     279 * {{{ ! }}} 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.
     280 * all the font styles marks have to be used in opening/closing pairs,
     281   and they must nest properly; in particular, an `''` italic can't be paired
     282   with a `//` one, and `'''` can't be paired with `**`.
     283
     284== Headings
     285
     286You can create a heading by starting a line with one up to six ''equal'' characters (`=`) followed by a single space and the headline text.
     287
     288[=#hn]
     289The headline text can be followed by the same number of `=` characters, but this is not mandatory. That is, `=== Section3 ===` is identical to `=== Section3`.
     290
     291Finally, the heading might optionally be followed by an explicit id. If not, an implicit but nevertheless readable id will be generated.

    64316A new text paragraph is created whenever two blocks of text are separated by one or more empty lines.
    65317
    66318A forced line break can also be inserted, using:

    199 
    200 
    201 == Links ==
    202 
    203 Hyperlinks are automatically created for WikiPageNames and URLs. !WikiPageLinks can be disabled by prepending an exclamation mark "!" character, such as {{{!WikiPageLink}}}.
    204 
    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 
    215 Example:
    216 {{{
    217  * [http://www.edgewall.com/ Edgewall Software]

    226 
    227 
    228 === Trac Links ===
     495Cell headings can be specified by wrapping the content in a pair of `=` characters.
     496Note that the `=` characters have to stick to the cell separators:
     497||= Wiki Markup =||= Display =||
     498{{{#!td
     499  {{{
     500  ||        ||= stable =||= latest =||
     501  ||= 0.10 =||  0.10.5  || 0.10.6dev||
     502  ||= 0.11 =||  0.11.6  || 0.11.7dev||
     503  }}}
     504}}}
     505{{{#!td style="padding: 2em;"
     506||        ||= stable =||= latest =||
     507||= 0.10 =||  0.10.5  || 0.10.6dev||
     508||= 0.11 =||  0.11.6  || 0.11.7dev||
     509}}}
     510
     511Finally, specifying an empty cell means that the next non empty cell will span the empty cells:
     512||= Wiki Markup =||= Display =||
     513{{{#!td
     514  {{{
     515  || 1 || 2 || 3 ||
     516  |||| 1-2 || 3 ||
     517  || 1 |||| 2-3 ||
     518  |||||| 1-2-3 ||
     519  }}}
     520}}}
     521{{{#!td style="padding: 2em;"
     522|| 1 || 2 || 3 ||
     523|||| 1-2 || 3 ||
     524|| 1 |||| 2-3 ||
     525|||||| 1-2-3 ||
     526}}}
     527
     528Note 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:
     529||= Wiki Markup =||= Display =||
     530{{{#!td
     531  {{{
     532  ||=Text =||= Numbers =||

     540  }}}
     541}}}
     542{{{#!td style="padding: 2em;"
     543||=Text =||= Numbers =||

     550|| default ||       2.5||
     551}}}
     552
     553If 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:
     554
     555||= Wiki Markup =||
     556{{{#!td
     557  {{{
     558  || this is column 1 [https://trac.edgewall.org/newticket new ticket] || \
     559  || this is column 2 [https://trac.edgewall.org/roadmap the road ahead] || \
     560  || that's column 3 and last one ||
     561  }}}

     569}}}
     570
     571=== Complex Tables
     572
     573If 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].
     574
     575== Links
     576
     577Hyperlinks are automatically created for WikiPageNames and URLs. !WikiPageLinks can be disabled by prepending an exclamation mark (`!`), such as `!WikiPageLink`.
     578
     579||= Wiki Markup =||= Display =||

     586TitleIndex, https://www.edgewall.com/, !NotAlink
     587}}}
     588
     589Links can be given a more descriptive title by writing the link followed by a space and a title and all this inside square brackets.
     590If 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.

     607
     608Following 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.
     609
     610{{{#!td
     611  {{{

     628
     629'''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].
     630So 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.
     631
     632== Trac Links
    229633
    230634Wiki 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
    235  * ...
    236 }}}

    247 == Escaping Links and WikiPageNames ==
    248 
    249 You may avoid making hyperlinks out of TracLinks by preceding an expression with a single "!" (exclamation mark).
    250 
    251 Example:
     654 * targeting other Trac instances,
     655   so called InterTrac links:
     656   - Tickets: #Trac1 or Trac:ticket:1
     657   - Changesets: [Trac1] or Trac:changeset:1
     658}}}
     659
     660There are many more flavors of Trac links, see TracLinks for more in-depth information and a reference for all the default link resolvers.
     661
     662== Setting Anchors
     663
     664An anchor, or more correctly speaking, an [https://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, to uniquely identify a position in the document:
     665
    252666{{{
     667[=#point1]
     668}}}
     669
     670This syntax was chosen to match the format for explicitly naming the header id [#Headings documented above]:
     671{{{
     672== Long title == #title
     673}}}
     674
     675It is also very close to the syntax for the corresponding link to that anchor:
     676{{{
     677[#point1]
     678}}}
     679
     680Optionally, a label can be given to the anchor:
     681{{{
     682[=#point1 '''Point 1''']
     683}}}
     684
     685||= Wiki Markup =||= Display =||
     686|----------------------------------
     687{{{#!td
     688  {{{
     689  [#point2 jump to the second point]

     701  Point2:  [=#point2] Jump here
     702}}}
     703
     704For 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)^)]]`.

     732
     733== Images
    263734
    264735Urls ending with `.png`, `.gif` or `.jpg` are no longer automatically interpreted as image links, and converted to `<img>` tags.
    265736
    266 You now have to use the ![[Image]] macro (see below).
    267 
    268 
    269 == Macros ==
    270 
    271 Macros are ''custom functions'' to insert dynamic content in a page.
    272 
    273 Example:
    274 {{{
    275  [[Timestamp]]
    276 }}}
    277 
    278 Display:
    279  [[Timestamp]]
     737You 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)]]`.
     738
     739In addition to the current page, it is possible to refer to other resources:
     740 * `[[Image(wiki:WikiFormatting:picture.gif)]]` (referring to attachment on another page)
     741 * `[[Image(ticket:1:picture.gif)]]` (file attached to a ticket)
     742 * `[[Image(htdocs:picture.gif)]]` (referring to a file inside the [TracEnvironment environment] `htdocs` directory)
     743 * `[[Image(source:/trunk/trac/htdocs/trac_logo_mini.png)]]` (a file in repository)
