    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, such as:
    6  - [#CodeHighlightingSupport syntax highlighting] or for rendering text verbatim
    7  - rendering [#HTMLrelated Wiki markup inside a context], like inside <div> blocks or <span> or within <td> or <th> table cells
    8  - using an alternative markup syntax, like [wiki:WikiHtml raw HTML] and [wiki:WikiRestructuredText Restructured Text] or [http://www.textism.com/tools/textile/ textile]

     5Wiki processors can be used in any Wiki text throughout Trac,
     6for 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

    20 Immediately after the `{{{` or on the line just below, add `#!` followed by the ''processor name'':
     26Immediately after the `{{{` or on the line just below,
     27add `#!` followed by the ''processor name''.

    3037This is the "shebang" notation, familiar to most UNIX users.
    3138
    32 Besides their content, some Wiki processors can also accept ''parameters'', which are then given as `key=value` pairs after the processor name and on the same line. If `value` has to contain space, as it's often the case for the style parameter, a quoted string can be used (`key="value with space"`).
    33 
    34 As some processors are meant to process Wiki markup, it's quite possible to ''nest'' processor blocks.
    35 You may want to indent the content of nested blocks for increased clarity, this extra indentation will be ignored when processing the content.

    142154The following processors are included in the Trac distribution:
    143155
    144156|| '''`#!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)'' ||
    147 |||| ||
    148 ||||= '''[=#HTMLrelated HTML related]''' =||
     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|||| ||
     159||||= '''HTML related''' =||
    149160|| '''`#!html`''' || Insert custom HTML in a wiki page. ||
    150161|| '''`#!htmlcomment`''' || Insert an HTML comment in a wiki page (''since 0.12''). ||
    … …  
    154165|| '''`#!td`''' || Wrap an arbitrary Wiki content inside a <td> element (''since 0.12'') ||
    155166|| '''`#!th`''' || Wrap an arbitrary 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'') ||
    157 || '''`#!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'') ||
     167|| '''`#!tr`''' || Can optionally be used for wrapping `#!td` and `#!th` blocks, either for specifying row attributes of better visual grouping (''since 0.12'') ||
    158168|| || See WikiHtml for example usage and more details about these processors. ||

    162172|| '''`#!textile`''' || Supported if [http://cheeseshop.python.org/pypi/textile Textile] is installed. See [http://www.textism.com/tools/textile/ a Textile reference]. ||
