|
||
|

|

|
*
|

|
* Using the @c MTLikeTextile class is exactly the same as using @c

* Textile. Simply use <code>$textile = new MTLikeTextile;</code>
|
||
|
* instead of <code>$textile = new Textile;</code> to create a Textile

|
* @section abstract ABSTRACT
|
||
|
*
|
||
|
* Textile.php is a PHP-based implementation of Dean Allen's Textile
|
||
|
* syntax. Textile is shorthand for doing common formatting tasks.
|
||
|
*
|
||
|
* @section syntax SYNTAX
|
||
|
*
|
||
|
* Textile processes text in units of blocks and lines.
|
||
|
* A block might also be considered a paragraph, since blocks
|
||
|
* are separated from one another by a blank line. Blocks
|
||
|
* can begin with a signature that helps identify the rest
|
||
|
* of the block content. Block signatures include:
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li><b>p</b>
|
||
|
*
|
||
|
* A paragraph block. This is the default signature if no
|
||
|
* signature is explicitly given. Paragraphs are formatted
|
||
|
* with all the inline rules (see inline formatting) and
|
||
|
* each line receives the appropriate markup rules for
|
||
|
* the flavor of HTML in use. For example, newlines for XHTML
|
||
|
* content receive a \<br /\> tag at the end of the line
|
||
|
* (with the exception of the last line in the paragraph).
|
||
|
* Paragraph blocks are enclosed in a \<p\> tag.</li>
|
||
|
*
|
||
|
* <li><b>pre</b>
|
||
|
*
|
||
|
* A pre-formatted block of text. Textile will not add any
|
||
|
* HTML tags for individual lines. Whitespace is also preserved.
|
||
|
*
|
||
|
* Note that within a "pre" block, \< and \> are
|
||
|
* translated into HTML entities automatically.</li>
|
||
|
*
|
||
|
* <li><b>bc</b>
|
||
|
*
|
||
|
* A "bc" signature is short for "block code", which implies
|
||
|
* a preformatted section like the 'pre' block, but it also
|
||
|
* gets a \<code\> tag (or for XHTML 2, a \<blockcode\>
|
||
|
* tag is used instead).
|
||
|
*
|
||
|
* Note that within a "bc" block, \< and \> are
|
||
|
* translated into HTML entities automatically.</li>
|
||
|
*
|
||
|
* <li><b>table</b>
|
||
|
*
|
||
|
* For composing HTML tables. See the "TABLES" section for more
|
||
|
* information.</li>
|
||
|
*
|
||
|
* <li><b>bq</b>
|
||
|
*
|
||
|
* A "bq" signature is short for "block quote". Paragraph text
|
||
|
* formatting is applied to these blocks and they are enclosed
|
||
|
* in a \<blockquote\> tag as well as \<p\> tags
|
||
|
* within.</li>
|
||
|
*
|
||
|
* <li><b>h1, h2, h3, h4, h5, h6</b>
|
||
|
*
|
||
|
* Headline signatures that produce \<h1\>, etc. tags.
|
||
|
* You can adjust the relative output of these using the
|
||
|
* head_offset attribute.</li>
|
||
|
*
|
||
|
* <li><b>clear</b>
|
||
|
*
|
||
|
* A 'clear' signature is simply used to indicate that the next
|
||
|
* block should emit a CSS style attribute that clears any
|
||
|
* floating elements. The default behavior is to clear "both",
|
||
|
* but you can use the left (\< or right \>) alignment
|
||
|
* characters to indicate which side to clear.</li>
|
||
|
*
|
||
|
* <li><b>dl</b>
|
||
|
*
|
||
|
* A "dl" signature is short for "definition list". See the
|
||
|
* "LISTS" section for more information.</li>
|
||
|
*
|
||
|
* <li><b>fn</b>
|
||
|
*
|
||
|
* A "fn" signature is short for "footnote". You add a number
|
||
|
* following the "fn" keyword to number the footnote. Footnotes
|
||
|
* are output as paragraph tags but are given a special CSS
|
||
|
* class name which can be used to style them as you see fit.</li>
|
||
|
*
|
||
|
* </ul>
|
||
|
*
|
||
|
* All signatures should end with a period and be followed
|
||
|
* with a space. Inbetween the signature and the period, you
|
||
|
* may use several parameters to further customize the block.
|
||
|
* These include:
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li><b><code>{style rule}</code></b>
|
||
|
*
|
||
|
* A CSS style rule. Style rules can span multiple lines.</li>
|
||
|
*
|
||
|
* <li><b><code>[ll]</code></b>
|
||
|
*
|
||
|
* A language identifier (for a "lang" attribute).</li>
|
||
|
*
|
||
|
* <li><b><code>(class)</code> or <code>(#id)</code> or <code>(class#id)</code></b>
|
||
|
*
|
||
|
* For CSS class and id attributes.</li>
|
||
|
*
|
||
|
* <li><b><code>\></code>, <code>\<</code>, <code>=</code>, <code>\<\></code></b>
|
||
|
*
|
||
|
* Modifier characters for alignment. Right-justification, left-justification,
|
||
|
* centered, and full-justification.</li>
|
||
|
*
|
||
|
* <li><b><code>(</code> (one or more)</b>
|
||
|
*
|
||
|
* Adds padding on the left. 1em per "(" character is applied.
|
||
|
* When combined with the align-left or align-right modifier,
|
||
|
* it makes the block float.</li>
|
||
|
*
|
||
|
* <li><b><code>)</code> (one or more)</b>
|
||
|
*
|
||
|
* Adds padding on the right. 1em per ")" character is applied.
|
||
|
* When combined with the align-left or align-right modifier,
|
||
|
* it makes the block float.</li>
|
||
|
*
|
||
|
* <li><b><code>|filter|</code> or <code>|filter|filter|filter|</code></b>
|
||
|
*
|
||
|
* A filter may be invoked to further format the text for this
|
||
|
* signature. If one or more filters are identified, the text
|
||
|
* will be processed first using the filters and then by
|
||
|
* Textile's own block formatting rules.</li>
|
||
|
*
|
||
|
* </ul>
|
||
|
*
|
||
|
* @subsection extendedblocks Extended Blocks
|
||
|
*
|
||
|
* Normally, a block ends with the first blank line encountered.
|
||
|
* However, there are situations where you may want a block to continue
|
||
|
* for multiple paragraphs of text. To cause a given block signature
|
||
|
* to stay active, use two periods in your signature instead of one.
|
||
|
* This will tell Textile to keep processing using that signature
|
||
|
* until it hits the next signature is found.
|
||
|
*
|
||
|
* For example:
|
||
|
* <pre>
|
||
|
* bq.. This is paragraph one of a block quote.
|
||
|
*
|
||
|
* This is paragraph two of a block quote.
|
||
|
*
|
||
|
* p. Now we're back to a regular paragraph.
|
||
|
* </pre>
|
||
|
* You can apply this technique to any signature (although for
|
||
|
* some it doesn't make sense, like "h1" for example). This is
|
||
|
* especially useful for "bc" blocks where your code may
|
||
|
* have many blank lines scattered through it.
|
||
|
*
|
||
|
* @subsection escaping Escaping
|
||
|
*
|
||
|
* Sometimes you want Textile to just get out of the way and
|
||
|
* let you put some regular HTML markup in your document. You
|
||
|
* can disable Textile formatting for a given block using the '=='
|
||
|
* escape mechanism:
|
||
|
* <pre>
|
||
|
* p. Regular paragraph
|
||
|
*
|
||
|
* ==
|
||
|
* Escaped portion -- will not be formatted
|
||
|
* by Textile at all
|
||
|
* ==
|
||
|
*
|
||
|
* p. Back to normal.
|
||
|
* </pre>
|
||
|
* You can also use this technique within a Textile block,
|
||
|
* temporarily disabling the inline formatting functions:
|
||
|
* <pre>
|
||
|
* p. This is ==*a test*== of escaping.
|
||
|
* </pre>
|
||
|
* @subsection inlineformatting Inline Formatting
|
||
|
*
|
||
|
* Formatting within a block of text is covered by the "inline"
|
||
|
* formatting rules. These operators must be placed up against
|
||
|
* text/punctuation to be recognized. These include:
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li><b><code>*strong*</code></b>
|
||
|
*
|

|

* <pre>
|

|
* Textile is *way* cool.
|
||
|
*
|
||
|
* Textile is *_way_* cool.
|
||
|
* </pre>
|
||
|
* Now this won't work, because the formatting
|
||
|
* characters need whitespace before and after
|
||
|
* to be properly recognized.
|
||
|
* <pre>
|
||
|
* Textile is way c*oo*l.
|
||
|
* </pre>
|
||
|
* However, you can supply braces or brackets to
|
||
|
* further clarify that you want to format, so
|
||
|
* this would work:
|
||
|
* <pre>
|
||
|
* Textile is way c[*oo*]l.
|
||
|
* </pre>
|
||
|
* @subsection footnotes Footnotes
|
||
|
*
|
||
|
* You can create footnotes like this:
|
||
|
* <pre>
|
||
|
* And then he went on a long trip[1].
|
||
|
* </pre>
|
||
|
* By specifying the brackets with a number inside, Textile will
|
||
|
* recognize that as a footnote marker. It will replace that with
|
||
|
* a construct like this:
|
||
|
* <pre>
|
||
|
* And then he went on a long
|
||
|
* trip<sup class="footnote"><a href="#fn1">1</a></sup>
|
||
|
* </pre>
|
||
|
* To supply the content of the footnote, place it at the end of your
|
||
|
* document using a "fn" block signature:
|
||
|
* <pre>
|
||
|
* fn1. And there was much rejoicing.
|
||
|
* </pre>
|
||
|
* Which creates a paragraph that looks like this:
|
||
|
* <pre>
|
||
|
* <p class="footnote" id="fn1"><sup>1</sup> And there was
|
||
|
* much rejoicing.</p>
|
||
|
* </pre>
|
||
|
* @subsection links Links
|
||
|
*
|
||
|
* Textile defines a shorthand for formatting hyperlinks.
|
||
|
* The format looks like this:
|
||
|
* <pre>
|
||
|
* "Text to display":http://example.com
|
||
|
* </pre>
|
||
|
* In addition to this, you can add 'title' text to your link:
|
||
|
* <pre>
|
||
|
* "Text to display (Title text)":http://example.com
|
||
|
* </pre>
|
||
|
* The URL portion of the link supports relative paths as well
|
||
|
* as other protocols like ftp, mailto, news, telnet, etc.
|
||
|
* <pre>
|
||
|
* "E-mail me please":mailto:someone\@example.com
|
||
|
* </pre>
|
||
|
* You can also use single quotes instead of double-quotes if
|
||
|
* you prefer. As with the inline formatting rules, a hyperlink
|
||
|
* must be surrounded by whitespace to be recognized (an
|
||
|
* exception to this is common punctuation which can reside
|
||
|
* at the end of the URL). If you have to place a URL next to
|
||
|
* some other text, use the bracket or brace trick to do that:
|
||
|
* <pre>
|
||
|
* You["gotta":http://example.com]seethis!
|
||
|
* </pre>
|
||
|
* Textile supports an alternate way to compose links. You can
|
||
|
* optionally create a lookup list of links and refer to them
|
||
|
* separately. To do this, place one or more links in a block
|
||
|
* of it's own (it can be anywhere within your document):
|
||
|
* <pre>
|
||
|
* [excom]http://example.com
|
||
|
* [exorg]http://example.org
|
||
|
* </pre>
|
||
|
* For a list like this, the text in the square brackets is
|
||
|
* used to uniquely identify the link given. To refer to that
|
||
|
* link, you would specify it like this:
|
||
|
* <pre>
|
||
|
* "Text to display":excom
|
||
|
* </pre>
|
||
|
* Once you've defined your link lookup table, you can use
|
||
|
* the identifiers any number of times.
|
||
|
*
|
||
|
* @subsection images Images
|
||
|
*
|
||
|
* Images are identified by the following pattern:
|
||
|
* <pre>
|
||
|
* !/path/to/image!
|
||
|
* </pre>
|
||
|
* Image attributes may also be specified:
|
||
|
* <pre>
|
||
|
* !/path/to/image 10x20!
|
||
|
* </pre>
|
||
|
* Which will render an image 10 pixels wide and 20 pixels high.
|
||
|
* Another way to indicate width and height:
|
||
|
* <pre>
|
||
|
* !/path/to/image 10w 20h!
|
||
|
* </pre>
|
||
|
* You may also redimension the image using a percentage.
|
||
|
* <pre>
|
||
|
* !/path/to/image 20%x40%!
|
||
|
* </pre>
|
||
|
* Which will render the image at 20% of it's regular width
|
||
|
* and 40% of it's regular height.
|
||
|
*
|
||
|
* Or specify one percentage to resize proprotionately:
|
||
|
* <pre>
|
||
|
* !/path/to/image 20%!
|
||
|
* </pre>
|
||
|
* Alt text can be given as well:
|
||
|
* <pre>
|
||
|
* !/path/to/image (Alt text)!
|
||
|
* </pre>
|
||
|
* The path of the image may refer to a locally hosted image or
|
||
|
* can be a full URL.
|
||
|
*
|
||
|
* You can also use the following modifiers after the opening '!'
|
||
|
* character:
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li><b><code>\<</code></b>
|
||
|
*
|
||
|
* Align the image to the left (causes the image to float if
|
||
|
* CSS options are enabled).</li>
|
||
|
*
|
||
|
* <li><b><code>\></code></b>
|
||
|
*
|
||
|
* Align the image to the right (causes the image to float if
|
||
|
* CSS options are enabled).</li>
|
||
|
*
|
||
|
* <li><b><code>-</code> (dash)</b>
|
||
|

|
||
|
*
|
||
|
* <li><b><code>^</code></b>
|
||
|
*
|
||
|

|
||
|
*
|
||
|
* <li><b><code>~</code> (tilde)</b>
|
||
|
*
|
||
|
* Aligns the image to the bottom.</li>
|
||
|
*
|
||
|
* <li><b><code>{style rule}</code></b>
|
||
|
*
|
||
|
* Applies a CSS style rule to the image.</li>
|
||
|
*
|
||
|
* <li><b><code>(class)</code> or <code>(#id)</code> or <code>(class#id)</code></b>
|
||
|
*
|
||
|
* Applies a CSS class and/or id to the image.</li>
|
||
|
*
|
||
|
* <li><b><code>(</code> (one or more)</b>
|
||
|
*
|
||
|
* Pads 1em on the left for each '(' character.</li>
|
||
|
*
|
||
|
* <li><b><code>)</code> (one or more)</b>
|
||
|
*
|
||
|
* Pads 1em on the right for each ')' character.</li>
|
||
|
*
|
||
|
* </ul>
|
||
|
*
|
||
|
* @subsection characterreplacements Character Replacements
|
||
|
*
|
||
|
* A few simple, common symbols are automatically replaced:
|
||
|
* <pre>
|
||
|
* (c)
|
||
|
* (r)
|
||
|
* (tm)
|
||
|
* </pre>
|
||
|
* In addition to these, there are a whole set of character
|
||
|
* macros that are defined by default. All macros are enclosed
|
||
|
* in curly braces. These include:
|
||
|
* <pre>
|
||
|
* {c|} or {|c} cent sign
|
||
|
* {L-} or {-L} pound sign
|
||
|
* {Y=} or {=Y} yen sign
|
||
|
* </pre>
|
||
|
* Many of these macros can be guessed. For example:
|
||
|
* <pre>
|
||
|
* {A'} or {'A}
|
||
|
* {a"} or {"a}
|
||
|
* {1/4}
|
||
|
* {*}
|
||
|
* {:)}
|
||
|
* {:(}
|
||
|
* </pre>
|
||
|
* @subsection lists Lists
|
||
|
*
|
||
|
* Textile also supports ordered and unordered lists.
|
||
|
* You simply place an asterisk or pound sign, followed
|
||
|
* with a space at the start of your lines.
|
||
|
*
|
||
|
* Simple lists:
|
||
|
* <pre>
|
||
|
* * one
|
||
|
* * two
|
||
|
* * three
|
||
|
* </pre>
|
||
|
* Multi-level lists:
|
||
|
* <pre>
|
||
|
* * one
|
||
|
* ** one A
|
||
|
* ** one B
|
||
|
* *** one B1
|
||
|
* * two
|
||
|
* ** two A
|
||
|
* ** two B
|
||
|
* * three
|
||
|
* </pre>
|
||
|
* Ordered lists:
|
||
|
* <pre>
|
||
|
* # one
|
||
|
* # two
|
||
|
* # three
|
||
|
* </pre>
|
||
|
* Styling lists:
|
||
|
* <pre>
|
||
|
* (class#id)* one
|
||
|
* * two
|
||
|
* * three
|
||
|
* </pre>
|
||
|
* The above sets the class and id attributes for the \<ul\>
|
||
|
* tag.
|
||
|
* <pre>
|
||
|
* *(class#id) one
|
||
|
* * two
|
||
|
* * three
|
||
|
* </pre>
|
||
|
* The above sets the class and id attributes for the first \<li\>
|
||
|
* tag.
|
||
|
*
|
||
|
* Definition lists:
|
||
|
* <pre>
|
||
|
* dl. textile:a cloth, especially one manufactured by weaving
|
||
|
* or knitting; a fabric
|
||
|
* format:the arrangement of data for storage or display.
|
||
|
* </pre>
|
||
|
* Note that there is no space between the term and definition. The
|
||
|
* term must be at the start of the line (or following the "dl"
|
||
|
* signature as shown above).
|
||
|
*
|
||
|
* @subsection tables Tables
|
||
|
*
|
||
|
* Textile supports tables. Tables must be in their own block and
|
||
|
* must have pipe characters delimiting the columns. An optional
|
||
|
* block signature of "table" may be used, usually for applying
|
||
|
* style, class, id or other options to the table element itself.
|
||
|
*
|
||
|
* From the simple:
|
||
|
* <pre>
|
||
|
* |a|b|c|
|
||
|
* |1|2|3|
|
||
|
* </pre>
|
||
|
* To the complex:
|
||
|
* <pre>
|
||
|
* table(fig). {color:red}_|Top|Row|
|
||
|
* {color:blue}|/2. Second|Row|
|
||
|
* |_{color:green}. Last|
|
||
|
* </pre>
|
||
|
* Modifiers can be specified for the table signature itself,
|
||
|
* for a table row (prior to the first '|' character) and
|
||
|
* for any cell (following the '|' for that cell). Note that for
|
||
|
* cells, a period followed with a space must be placed after
|
||
|
* any modifiers to distinguish the modifier from the cell content.
|
||
|
*
|
||
|
* Modifiers allowed are:
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li><b><code>{style rule}</code></b>
|
||
|
*
|
||
|
* A CSS style rule.</li>
|
||
|
*
|
||
|
* <li><b><code>(class)</code> or <code>(#id)</code> or <code>(class#id)</code></b>
|
||
|
*
|
||
|
* A CSS class and/or id attribute.</li>
|
||
|
*
|
||
|
* <li><b><code>(</code> (one or more)</b>
|
||
|
*
|
||
|
* Adds 1em of padding to the left for each '(' character.</li>
|
||
|
*
|
||
|
* <li><b><code>)</code> (one or more)</b>
|
||
|
*
|
||
|
* Adds 1em of padding to the right for each ')' character.</li>
|
||
|
*
|
||
|
* <li><b><code>\<</code></b>
|
||
|
*
|
||
|
* Aligns to the left (floats to left for tables if combined with the
|
||
|
* ')' modifier).</li>
|
||
|
*
|
||
|
* <li><b><code>\></code></b>
|
||
|
*
|
||
|
* Aligns to the right (floats to right for tables if combined with
|
||
|
* the '(' modifier).</li>
|
||
|
*
|
||
|
* <li><b><code>=</code></b>
|
||
|
*
|
||
|
* Aligns to center (sets left, right margins to 'auto' for tables).</li>
|
||
|
*
|
||
|
* <li><b><code>\<\></code></b>
|
||
|
*
|
||
|
* For cells only. Justifies text.</li>
|
||
|
*
|
||
|
* <li><b><code>^</code></b>
|
||
|
*
|
||
|
* For rows and cells only. Aligns to the top.</li>
|
||
|
*
|
||
|
* <li><b><code>~</code> (tilde)</b>
|
||
|
*
|
||
|
* For rows and cells only. Aligns to the bottom.</li>
|
||
|
*
|
||
|
* <li><b><code>_</code> (underscore)</b>
|
||
|
*
|
||
|
* Can be applied to a table row or cell to indicate a header
|
||
|
* row or cell.</li>
|
||
|
*
|
||
|
* <li><b><code>\\2</code> or <code>\\3</code> or <code>\\4</code>, etc.</b>
|
||
|
*
|
||
|
* Used within cells to indicate a colspan of 2, 3, 4, etc. columns.
|
||
|
* When you see "\\", think "push forward".</li>
|
||
|
*
|
||
|
* <li><b><code>/2</code> or <code>/3</code> or <code>/4</code>, etc.</b>
|
||
|
*
|
||
|
* Used within cells to indicate a rowspan of 2, 3, 4, etc. rows.
|
||
|
* When you see "/", think "push downward".</li>
|
||
|
*
|
||
|
* </ul>
|
||
|
*
|
||
|
* When a cell is identified as a header cell and an alignment
|
||
|
* is specified, that becomes the default alignment for
|
||
|
* cells below it. You can always override this behavior by
|
||
|
* specifying an alignment for one of the lower cells.

|
* @subsection cssnotes CSS Notes
|
||
|
*
|
||
|
* When CSS is enabled (and it is by default), CSS class names
|
||
|
* are automatically applied in certain situations.
|
||
|
*
|
||
|
* <ul>
|
||
|
*
|
||
|
* <li>Aligning a block or span or other element to
|
||
|
* left, right, etc.
|
||
|
*
|
||
|
* "left" for left justified, "right" for right justified,
|
||
|
* "center" for centered text, "justify" for full-justified
|
||
|
* text.</li>
|
||
|
*
|
||
|
* <li>Aligning an image to the top or bottom
|
||
|
*
|
||
|
* "top" for top alignment, "bottom" for bottom alignment,
|
||
|
* "middle" for middle alignment.</li>
|
||
|
*
|
||
|
* <li>Footnotes
|
||
|
*
|
||
|
* "footnote" is applied to the paragraph tag for the
|
||
|
* footnote text itself. An id of "fn" plus the footnote
|
||
|
* number is placed on the paragraph for the footnote as
|
||
|
* well. For the footnote superscript tag, a class of
|
||
|
* "footnote" is used.</li>
|
||
|
*
|
||
|
* <li>Capped text
|
||
|
*
|
||
|
* For a series of characters that are uppercased, a
|
||
|
* span is placed around them with a class of "caps".</li>
|
||
|

|
||
|
* </ul>

* @subsection miscellaneous Miscellaneous
|
||
|
*
|
||
|
* Textile tries to do it's very best to ensure proper XHTML
|
||
|
* syntax. It will even attempt to fix errors you may introduce
|
||
|
* writing in HTML yourself. Unescaped '&' characters within
|
||
|
* URLs will be properly escaped. Singlet tags such as br, img
|
||
|
* and hr are checked for the '/' terminator (and it's added
|
||
|
* if necessary). The best way to make sure you produce valid
|
||
|
* XHTML with Textile is to not use any HTML markup at all--
|
||

* Text::Textile was written by Brad Choate, \<brad at bradchoate dot com\>.
|
||
|
* It is an adaptation of Textile, developed by Dean Allen of Textism.com.
|
||
|
*
|
||
|
* Textile.php is a PHP port of Brad Choate's Text::Textile
|
||
|
* (Textile.pm) Perl module.
|
||
|
*
|
||
|
* Textile.php was ported by Jim Riggs \<textile at jimandlissa dot
|
||
|
* com\>. Great care has been taken to leave the Perl code in much the
|
||
|
* same form as Textile.pm. While changes were required due to
|
||
|
* syntactical differences between Perl and PHP, much of the code was
|
||
|
* left intact (even if alternative syntax or code optimizations could
|
||
|
* have been made in PHP), even to the point where one can compare
|
||
|
* functions/subroutines side by side between the two implementations.
|
||
|
* This has been done to ensure compatibility, reduce the possibility
|
||
|
* of introducing errors, and simplify maintainance as one version or
|
||
|
* the other is updated.
