    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://moinmo.in/ MoinMoin] and [trac:WikiCreole].
    8 
    9 
    10 This page will give you an in-depth explanation of the wiki markup available anywhere WikiFormatting is allowed.
    11 
    12 The ''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 
    14 A 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

    247237
    248238The Trac wiki supports the following font styles:
    … …  
    287277Notes:
    288278 * `{{{...}}}` 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.
    289  * {{{ ! }}} 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.
     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.
    290280 * all the font styles marks have to be used in opening/closing pairs,
    291    and they must nest properly (in particular, an `''` italic can't be paired
    292    with a `//` one, and `'''` can't be paired with `**`)
    293 
    294 
    295 == Headings ==
    296 
    297 You can create heading by starting a line with one up to six ''equal'' characters ("=")
    298 followed by a single space and the headline text.
     281   and they must nest properly; in particular, an `''` italic can't be paired
     282   with a `//` one, and `'''` can't be paired with `**`.

     284== Headings

     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.
    299287
    300288[=#hn]
    301 The headline text can be followed by the same number of "=" characters, but this is no longer mandatory.
     289The headline text can be followed by the same number of `=` characters, but this is not mandatory. That is, `=== Section3 ===` is identical to `=== Section3`.
    302290
    303291Finally, the heading might optionally be followed by an explicit id. If not, an implicit but nevertheless readable id will be generated.

    509494
    510 Cell headings can be specified by wrapping the content in a pair of '=' characters.
    511 Note that the '=' characters have to stick to the cell separators, like this:
     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:

    513498{{{#!td

    525510
    526 Finally, specifying an empty cell means that the next non empty cell will span the empty cells. For example:

    542527
    543 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:

    568 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.

    645 '''Note''': the [trac:WikiCreole] style for links is quick to type and
    646 certainly looks familiar as it's the one used on Wikipedia and in many
    647 other wikis. Unfortunately it conflicts with the syntax for [#Macros macros].
    648 So in the rare case when you need to refer to a page which is named after
    649 a macro (typical examples being TitleIndex, InterTrac and InterWiki),
    650 by writing `[[TitleIndex]]` you will actually call the macro instead of linking
    651 to the page.
