    33Processors are WikiMacros designed to provide alternative markup formats for the [TracWiki Wiki engine]. Processors can be thought of as ''macro functions to process user-edited text''.
    44
    5 Wiki processors can be used in any Wiki text throughout Trac,
    6 for various different purposes, like:
    7  - [#CodeHighlightingSupport syntax highlighting] or for rendering text verbatim,
    8  - rendering [#HTMLrelated Wiki markup inside a context],
    9    like inside <div> blocks or <span> or within <td> or <th> table cells,
    10  - using an alternative markup syntax, like [wiki:WikiHtml raw HTML] and
    11    [wiki:WikiRestructuredText Restructured Text],
    12    or [http://www.textism.com/tools/textile/ textile]

    39 Besides their content, some Wiki processors can also accept ''parameters'',
    40 which are then given as `key=value` pairs after the processor name,
    41 on the same line. If `value` has to contain space, as it's often the case for
    42 the style parameter, a quoted string can be used (`key="value with space"`).
    43 
    44 As some processors are meant to process Wiki markup, it's quite possible to
    45 ''nest'' processor blocks.
    46 You may want to indent the content of nested blocks for increased clarity,
    47 this extra indentation will be ignored when processing the content.

    154142The following processors are included in the Trac distribution:
    155143
    156 || '''`#!default`''' || Present the text verbatim in a preformatted text block. This is the same as specifying ''no'' processor name (and no `#!`) ||
    157 || '''`#!comment`''' || Do not process the text in this section (i.e. contents exist only in the plain text - not in the rendered page). ||
    158 || '''`#!rtl`''' || Introduce a Right-To-Left block with appropriate CSS direction and styling ''(since 0.12.2)'' ||
     144|| '''`#!default`''' || Present the text verbatim in a preformatted text block. This is the same as specifying ''no'' processor name (and no `#!`). ||
     145|| '''`#!comment`''' || Do not process the text in this section, i.e. contents exist only in the plain text - not in the rendered page. ||
     146|| '''`#!rtl`''' || Introduce a Right-To-Left block with appropriate CSS direction and styling. ''(since 0.12.2)'' ||
    159147|||| ||
    160148||||= '''[=#HTMLrelated HTML related]''' =||
    161149|| '''`#!html`''' || Insert custom HTML in a wiki page. ||
    162 || '''`#!htmlcomment`''' || Insert an HTML comment in a wiki page (''since 0.12''). ||
     150|| '''`#!htmlcomment`''' || Insert an HTML comment in a wiki page. (''since 0.12'') ||
    163151|| || Note that `#!html` blocks have to be ''self-contained'', i.e. you can't start an HTML element in one block and close it later in a second block. Use the following processors for achieving a similar effect.  ||
    164 || '''`#!div`''' || Wrap an arbitrary Wiki content inside a <div> element (''since 0.11''). ||
    165 || '''`#!span`''' || Wrap an arbitrary Wiki content inside a <span> element (''since 0.11''). ||
    166 || '''`#!td`''' || Wrap an arbitrary Wiki content inside a <td> element (''since 0.12'') ||
    167 || '''`#!th`''' || Wrap an arbitrary Wiki content inside a <th> element (''since 0.12'') ||
    168 || '''`#!tr`''' || Can optionally be used for wrapping `#!td` and `#!th` blocks, either for specifying row attributes or better visual grouping (''since 0.12'') ||
     152|| '''`#!div`''' || Wrap wiki content inside a <div> element. ||
     153|| '''`#!span`''' || Wrap wiki content inside a <span> element. ||
     154|| '''`#!td`''' || Wrap wiki content inside a <td> element. (''since 0.12'') ||
     155|| '''`#!th`''' || Wrap wiki content inside a <th> element. (''since 0.12'') ||
     156|| '''`#!tr`''' || Can optionally be used for wrapping `#!td` and `#!th` blocks, either for specifying row attributes or better visual grouping. (''since 0.12'') ||
    169157|| '''`#!table`''' || Can optionally be used for wrapping `#!tr`, `#!td` and `#!th` blocks, for specifying table attributes. One current limitation however is that tables cannot be nested. (''since 0.12'') ||
    170158|| || See WikiHtml for example usage and more details about these processors. ||

    253 In fact they work the same way, only the usage syntax differs.
