    4 
    5 Wiki markup is a core feature in Trac, tightly integrating all the other parts of Trac into a flexible and powerful whole.
    6 
    7 Trac 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 
    9 This page will give you an in-depth explanation of the wiki markup available anywhere WikiFormatting is allowed.
    10 
    11 The 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 
    13 A 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.

    243 
    244 == Font Styles
    245 
    246 The 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 
    285 Notes:
    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 
    294 You 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]
    297 The headline text can be followed by the same number of "=" characters, but this is not mandatory. That is, `=== Section3 ===` is identical to `=== Section3`.
    298 
    299 Finally, 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 
    324 A new text paragraph is created whenever two blocks of text are separated by one or more empty lines.
    325 
    326 A 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 
    352 The wiki supports both ordered/numbered and unordered lists.
    353 
    354 Example:
    355 ||= Wiki Markup =||= Display =||
    356 {{{#!td
    357   {{{
    358    * Item 1
    359      * Item 1.1

    361         * Item 1.1.2
    362         * Item 1.1.3
    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
    374         i. Item 1.b.i
    375         i. Item 1.b.ii
    376    1. Item 2
    377   And numbered lists can also be restarted
    378   with an explicit number:
    379    3. Item 3
    380   }}}
    381 }}}
    382 {{{#!td
    383  * Item 1
    384    * Item 1.1
    385       * Item 1.1.1   
    386       * Item 1.1.2
    387       * Item 1.1.3
    388    * Item 1.2
    389  * Item 2
    390 - items can start at the beginning of a line
    391   and they can span multiple lines
    392   - be careful though to continue the line
    393   with the appropriate indentation, otherwise
    394 that will start a new paragraph...
    395 
    396  1. Item 1
    397    a. Item 1.a
    398    a. Item 1.b

    400       i. Item 1.b.ii
    401  1. Item 2
    402 And numbered lists can also be restarted with an explicit number:
    403  3. Item 3
    404 }}}
    405 
    406 == Definition Lists
    407 
    408 The wiki also supports definition lists.
    409 
    410 ||= Wiki Markup =||= Display =||
    411 {{{#!td
    412   {{{
    413    llama::
    414      some kind of mammal, with hair
    415    ppython::
    416      some kind of reptile, without hair
    417      (can you spot the typo?)
    418   }}}
    419 }}}
    420 {{{#!td
    421  llama::
    422    some kind of mammal, with hair
    423  ppython::
    424    some kind of reptile, without hair
    425    (can you spot the typo?)
    426 }}}
    427 
    428 Note that you need a space in front of the defined term.
    429 
    430 == Preformatted Text
    431 
    432 Block 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   {{{
    438   def HelloWorld():
    439       print '''Hello World'''
    440   }}}
    441   }}}
    442 }}}
    443 {{{#!td
    444   {{{
    445   def HelloWorld():
    446       print '''Hello World'''
    447   }}}
    448 }}}
    449 
    450 Note that this kind of block is also used for selecting lines that should be processed through WikiProcessors.
    451 
    452 == Blockquotes
    453 
    454 In order to mark a paragraph as blockquote, indent that paragraph with two spaces.
    455 
    456 ||= Wiki Markup =||= Display =||
    457 {{{#!td
    458 {{{
    459 Paragraph
    460   This text is a quote from someone else.
    461 }}}
    462 }}}
    463 {{{#!td
    464 Paragraph
    465   This text is a quote from someone else.
    466 }}}
    467 
    468 == Discussion Citations
    469 
    470 To 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   {{{
    475   >> Someone's original text
    476   > Someone else's reply text
    477   >  - which can be any kind of Wiki markup
    478   My reply text
    479   }}}
    480 }}}
    481 {{{#!td
    482 >> Someone's original text
    483 > Someone else's reply text
    484 >  - which can be any kind of Wiki markup
    485 My reply text
    486 }}}
    487 
    488 == Tables
    489 === Simple Tables
    490 
    491 Simple tables can be created like this:
    492 ||= Wiki Markup =||= Display =||
    493 {{{#!td
    494   {{{
    495   ||Cell 1||Cell 2||Cell 3||
    496   ||Cell 4||Cell 5||Cell 6||
    497   }}}
    498 }}}
    499 {{{#!td style="padding: 2em;"
    500 ||Cell 1||Cell 2||Cell 3||
    501 ||Cell 4||Cell 5||Cell 6||
    502 }}}
    503 
    504 Cell headings can be specified by wrapping the content in a pair of '=' characters.
    505 Note 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 
    520 Finally, 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 
    537 Note 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 
    562 If 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] || \
    569   || that's column 3 and last one ||
    570   }}}
    571 }}}
    572 |-------------
    573 ||= Display =||
    574 {{{#!td style="padding: 2em;"

    577 || that's column 3 and last one ||
    578 }}}
    579 
    580 === Complex Tables
    581 
    582 If 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 
    586 Hyperlinks 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
    595 TitleIndex, http://www.edgewall.com/, !NotAlink
    596 }}}
    597 
    598 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.
    599 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.
    600 
    601 ||= Wiki Markup =||= Display =||
    602 {{{#!td
    603   {{{
    604    * [http://www.edgewall.com Edgewall Software]
    605    * [wiki:TitleIndex Title Index]

    614    * [wiki:ISO9000]
    615 }}}
    616 
    617 Following 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]]
    622    * [[wiki:TitleIndex|Title Index]]
    623      or even [[TitleIndex|Title Index]]
    624    * [[wiki:TitleIndex]]
    625      ''' but not ![[TitleIndex]]! '''
    626    * [[ISO9000]]
    627   }}}
    628 }}}
    629 {{{#!td
    630    * [[http://www.edgewall.com|Edgewall Software]]
    631    * [[wiki:TitleIndex|Title Index]]
    632      or even [[TitleIndex|Title Index]]
    633    * [[wiki:TitleIndex]]
    634      ''' but not ![[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].
    639 So 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 
    643 Wiki 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 
    669 There 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 
    673 An 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 
    679 This 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 
    684 It is also very close to the syntax for the corresponding link to that anchor:
    685 {{{
    686 [#point1]
    687 }}}
    688 
    689 Optionally, 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 
    713 For 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 
    717 You 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   {{{
    726 Various forms of escaping for list markup:
    727  ^^- escaped minus sign \\
    728  ^^1. escaped number  \\
    729  ^^* escaped asterisk sign
    730   }}}
    731 }}}
    732 {{{#!td
    733  !NoHyperLink
    734  !#42 is not a link
    735 
    736 Various forms of escaping for list markup:
    737  ^^- escaped minus sign \\
    738  ^^1. escaped number  \\
    739  ^^* escaped asterisk sign
    740 }}}
    741 
    742 == Images
    743 
    744 Urls ending with `.png`, `.gif` or `.jpg` are no longer automatically interpreted as image links, and converted to `<img>` tags.
    745 
    746 You 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 
    748 In 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)]]

    760 {{{#!td
    761 [[Image(htdocs:../common/trac_logo_mini.png)]]
    762 }}}
    763 
    764 See WikiMacros for further documentation on the `[[Image()]]` macro, which has several useful options (`title=`, `link=`, etc.)
    765 
    766 == Macros
    767 
    768 Macros are ''custom functions'' to insert dynamic content in a page.
    769 
    770 ||= Wiki Markup =||= Display =||

    778 }}}
    779 
    780 See WikiMacros for more information, and a list of installed macros.
    781 
    782 The detailed help for a specific macro can also be obtained more directly by appending a "?" to the macro name.
    783

    792 }}}
    793 
    794 == Processors
    795 
    796 Trac supports alternative markup formats using WikiProcessors. For example, processors are used to write pages in
    797 [wiki:WikiRestructuredText reStructuredText] or [wiki:WikiHtml HTML].
