Processors can be thought of as *macro functions to process user-edited text*. - -Wiki processors can be used in any Wiki text throughout Trac, such as: - - - [#CodeHighlightingSupport syntax highlighting] or for rendering text verbatim - - rendering [#HTMLrelated Wiki markup inside a context], like inside
blocks or or within or table cells - - using an alternative markup syntax, like [raw HTML] and [WikiRestructuredText Restructured Text] or [http://www.textism.com/tools/textile/ textile](WikiHtml) - - -## Using Processors - -To use a processor on a block of text, first delimit the lines using a Wiki *code block*: -``` -``` -The lines -that should be processed... -``` -``` - -Immediately after the ````` or on the line just below, add `#!` followed by the ''processor name'': - -``` -``` -#!processorname -The lines -that should be processed... -``` -``` - -This is the "shebang" notation, familiar to most UNIX users. - -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"`). - -As some processors are meant to process Wiki markup, it's quite possible to *nest* processor blocks. -You may want to indent the content of nested blocks for increased clarity, this extra indentation will be ignored when processing the content. - -## Examples - -| Wiki Markup | Display | -|---|---| -```#!td colspan=2 align=center style="border: none" - - __Example 1__: Inserting raw HTML - -``` -|----------------------------------------------------------------- -```#!td style="border: none" -``` -``` -#!html -

This is the same as specifying *no* processor name (and no `#!`). | -|---|---| -| **`#comment`** | Do not process the text in this section, i.e. contents exist only in the plain text - not in the rendered page. | -| **`#rtl`** | Introduce a Right-To-Left block with appropriate CSS direction and styling. *(since 0.12.2)* | -|| | -|| **[=#HTMLrelated HTML related]** | -| **`#html`** | Insert custom HTML in a wiki page. | -| **`#htmlcomment`** | Insert an HTML comment in a wiki page. (*since 0.12*) | -| | 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. | -| **`#div`** | Wrap wiki content inside a
element. | -| **`#span`** | Wrap wiki content inside a element. | -| **`#td`** | Wrap wiki content inside a element. (*since 0.12*) | -| **`#th`** | Wrap wiki content inside a element. (*since 0.12*) | -| **`#tr`** | Can optionally be used for wrapping `#td` and `#th` blocks, either for specifying row attributes or better visual grouping. (*since 0.12*) | -| **`#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*) | -| | See WikiHtml for example usage and more details about these processors. | -|| | -|| **Other Markups** | -| **`#rst`** | Trac support for Restructured Text. See WikiRestructuredText. | -| **`#textile`** | Supported if [Textile] is installed. See [http://www.textism.com/tools/textile/ a Textile reference](http://cheeseshop.python.org/pypi/textile). | -|| | -|| **[=#CodeHighlightingSupport Code Highlighting Support]** | -| **`#c`** [**`#cpp`** (C++) [[BR]] **`#python`** [[BR]] **`#perl`** [[BR]] **`#ruby`** [[BR]] **`#php`** [[BR]] **`#asp`** [[BR]] **`#java`** [[BR]] **`#js`** (Javascript) [[BR]] **`#sql`** [[BR]] **`#xml`** (XML or HTML) [[BR]] **`#sh`** (Bourne/Bash shell) [[BR]] **etc.** [[BR]] | Trac includes processors to provide inline syntax highlighting for source code in various languages. [[BR]] [[BR]] Trac relies on [http://pygments.org Pygments] for syntax coloring. [[BR]] [[BR]]([BR]]) See TracSyntaxColoring for information about which languages are supported and how to enable support for more languages. | -|| | - - -Since 1.1.2 the default, coding highlighting and MIME-type processors support the argument `lineno` for adding line numbering to the code block. When a value is specified, as in `lineno=3`, the numbering will start at the specified value. When used in combination with the `lineno` argument, the `marks` argument is also supported for highlighting lines. A single line number, set of line numbers and range of line numbers are allowed. For example, `marks=3`, `marks=3-6`, `marks=3,5,7` and `marks=3-5,7` are all allowed. The specified values are relative to the numbered lines, so if `lineno=2` is specified to start the line numbering at 2, `marks=2` will result in the first line being highlighted. - -Using the MIME type as processor, it is possible to syntax-highlight the same languages that are supported when browsing source code. - -|| **MIME Type Processors** | -|---|---| -```#!tr -```#!td -Some examples: - ``` -```#!text/html -
