       Text::Textile is a Perl-based implementation of Dean Allen's Textile syntax. Textile is
       shorthand for doing common formatting tasks.


   new( [%options] )
       Instantiates a new Text::Textile object. Optional options can be passed to initialize the
       object. Attributes for the options key are the same as the get/set method names documented

   set( $attribute, $value )
       Used to set Textile attributes. Attribute names are the same as the get/set method names
       documented here.

   get( $attribute )
       Used to get Textile attributes. Attribute names are the same as the get/set method names
       documented here.

   disable_html( [$disable] )
       Gets or sets the "disable html" control, which allows you to prevent HTML tags from being
       used within the text processed.  Any HTML tags encountered will be removed if disable html
       is enabled. Default behavior is to allow HTML.

   flavor( [$flavor] )
       Assigns the HTML flavor of output from Text::Textile. Currently these are the valid
       choices: html, xhtml (behaves like "xhtml1"), xhtml1, xhtml2. Default flavor is "xhtml1".

       Note that the xhtml2 flavor support is experimental and incomplete (and will remain that
       way until the XHTML 2.0 draft becomes a proper recommendation).

   css( [$css] )
       Gets or sets the CSS support for Textile. If CSS is enabled, Textile will emit CSS rules.
       You may pass a 1 or 0 to enable or disable CSS behavior altogether. If you pass a hashref,
       you may assign the CSS class names that are used by Text::Textile. The following key names
       for such a hash are recognized:

           defaults to "right"

           defaults to "left"

           defaults to "center"

           defaults to "top"

           defaults to "bottom"

           defaults to "middle"

           defaults to "justify"

           defaults to "caps"

           defaults to "footnote"

           defaults to "fn"

   charset( [$charset] )
       Gets or sets the character set targeted for publication.  At this time, Text::Textile only
       changes its behavior if the "utf-8" character set is assigned.

       Specifically, if utf-8 is requested, any special characters created by Textile will be
       output as native utf-8 characters rather than HTML entities.

   docroot( [$path] )
       Gets or sets the physical file path to root of document files.  This path is utilized when
       images are referenced and size calculations are needed (the Image::Size module is used to
       read the image dimensions).

   trim_spaces( [$trim] )
       Gets or sets the "trim spaces" control flag. If enabled, this will clear any lines that
       have only spaces on them (the newline itself will remain).

   preserve_spaces( [$preserve] )
       Gets or sets the "preserve spaces" control flag. If enabled, this will replace any double
       spaces within the paragraph data with the &#8195; HTML entity (wide space). The default is
       0. Spaces will pass through to the browser unchanged and render as a single space.  Note
       that this setting has no effect on spaces within "<pre>", "<code>" or "<script>".

   filter_param( [$data] )
       Gets or sets a parameter that is passed to filters.

   filters( [\%filters] )
       Gets or sets a list of filters to make available for Text::Textile to use. Returns a hash
       reference of the currently assigned filters.

   char_encoding( [$encode] )
       Gets or sets the character encoding logical flag. If character encoding is enabled, the
       HTML::Entities package is used to encode special characters. If character encoding is
       disabled, only "<", ">", """ and "&" are encoded to HTML entities.

   disable_encode_entities( $boolean )
       Gets or sets the disable encode entities logical flag. If this value is set to true no
       entities are encoded at all. This also supersedes the "char_encoding" flag.

   handle_quotes( [$handle] )
       Gets or sets the "smart quoting" control flag. Returns the current setting.

   process( $str )
       Alternative method for invoking the textile method.

   textile( $str )
       Can be called either procedurally or as a method. Transforms $str using Textile markup

   format_paragraph( [$args] )
       Processes a single paragraph. The following attributes are allowed:

           The text to be processed.

   format_inline( [%args] )
       Processes an inline string (plaintext) for Textile syntax.  The following attributes are

           The text to be processed.

   format_macro( %args )
       Responsible for processing a particular macro. Arguments passed include:

       pre open brace character

           close brace character

           the macro to be executed

       The return value from this method would be the replacement text for the macro given. If
       the macro is not defined, it will return pre + macro + post, thereby preserving the
       original macro string.

   format_cite( %args )
       Processes text for a citation tag. The following attributes are allowed:

       pre Any text that comes before the citation.

           The text that is being cited.

           The URL of the citation.

           Any text that follows the citation.

   format_code( %args )
       Processes '@...@' type blocks (code snippets). The following attributes are allowed:

           The text of the code itself.

           The language (programming language) for the code.

   format_classstyle( $clsty, $class, $style )
       Returns a string of tag attributes to accommodate the class, style and symbols present in

       $clsty is checked for:

           style rules. If present, they are appended to $style.

           class and/or ID name declaration

       "(" (one or more)
           pad left characters

       ")" (one or more)
           pad right characters

           language declaration

       The attribute string returned will contain any combination of class, id, style and/or lang

   format_tag( %args )
       Constructs an HTML tag. Accepted arguments:

       tag the tag to produce

           the text to output inside the tag

       pre text to produce before the tag

           text to produce following the tag

           class and/or style attributes that should be assigned to the tag.

   format_list( %args )
       Takes a Textile formatted list (numeric or bulleted) and returns the markup for it. Text
       that is passed in requires substantial parsing, so the format_list method is a little
       involved. But it should always produce a proper ordered or unordered list. If it cannot
       (due to misbalanced input), it will return the original text. Arguments accepted:

           The text to be processed.

   format_block( %args )
       Processes "==xxxxx==" type blocks for filters. A filter would follow the open "=="
       sequence and is specified within pipe characters, like so:

           ==|filter|text to be filtered==

       You may specify multiple filters in the filter portion of the string. Simply comma delimit
       the filters you desire to execute. Filters are defined using the filters method.

   format_link( %args )
       Takes the Textile link attributes and transforms them into a hyperlink.

   format_url( %args )
       Takes the given $url and transforms it appropriately.

   format_span( %args )
   format_image( %args )
       Returns markup for the given image. $src is the location of the image, $extra contains the
       optional height/width and/or alt text. $url is an optional hyperlink for the image. $class
       holds the optional CSS class attribute.

       Arguments you may pass:

       src The "src" (URL) for the image. This may be a local path, ideally starting with a "/".
           Images can be located within the file system if the docroot method is used to specify
           where the docroot resides. If the image can be found, the image_size method is used to
           determine the dimensions of the image.

           Additional parameters for the image. This would include alt text, height/width
           specification or scaling instructions.

           Alignment attribute.

       pre Text to produce prior to the tag.

           Text to produce following the tag.

           Optional URL to connect with the image tag.

           Class and/or style attributes.

   format_table( %args )
       Takes a Wiki-ish string of data and transforms it into a full table.

   apply_filters( %args )
       The following attributes are allowed:

           The text to be processed.

           An array reference of filter names to run for the given text.

   encode_html( $html, $can_double_encode )
       Encodes input $html string, escaping characters as needed to HTML entities. This relies on
       the HTML::Entities package for full effect. If unavailable, encode_html_basic is used as a
       fallback technique. If the "char_encoding" flag is set to false, encode_html_basic is used

   decode_html( $html )
       Decodes HTML entities in $html to their natural character equivelants.

   encode_html_basic( $html, $can_double_encode )
       Encodes the input $html string for the following characters: <, >, & and ". If
       $can_double_encode is true, all ampersand characters are escaped even if they already
       were.  If $can_double_encode is false, ampersands are only escaped when they aren't part
       of a HTML entity already.

   image_size( $file )
       Returns the size for the image identified in $file. This method relies upon the
       Image::Size Perl package. If unavailable, image_size will return undef. Otherwise, the
       expected return value is a list of the width and height (in that order), in pixels.

   encode_url( $str )
       Encodes the query portion of a URL, escaping characters as necessary.

   mail_encode( $email )
       Encodes the email address in $email for "mailto:" links.

   process_quotes( $str )
       Processes string, formatting plain quotes into curly quotes.

       Returns a hashref of macros that are assigned to be processed by default within the
       format_inline method.

   _halign( $alignment )
       Returns the alignment keyword depending on the symbol passed.

           becomes "justify"

       "<" becomes "left"

       ">" becomes "right"

       "=" becomes "center"

   _valign( $alignment )
       Returns the alignment keyword depending on the symbol passed.

       "^" becomes "top"

       "~" becomes "bottom"

       "-" becomes "middle"

   _imgalign( $alignment )
       Returns the alignment keyword depending on the symbol passed.  The following alignment
       symbols are recognized, and given preference in the order listed:

       "^" becomes "top"

       "~" becomes "bottom"

       "-" becomes "middle"

       "<" becomes "left"

       ">" becomes "right"

   _repl( \@arr, $str )
       An internal routine that takes a string and appends it to an array.  It returns a marker
       that is used later to restore the preserved string.

   _tokenize( $str )
       An internal routine responsible for breaking up a string into individual tag and plaintext

       Sets the default CSS names for CSS controlled markup. This is an internal function that
       should not be called directly.

   _strip_borders( $pre, $post )
       This utility routine will take "border" characters off of the given $pre and $post strings
       if they match one of these conditions:

           $pre starts with "[", $post ends with "]"
           $pre starts with "{", $post ends with "}"

       If neither condition is met, then the $pre and $post values are left untouched.


       Text::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:

       p   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.

       pre 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

       bc  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

           For composing HTML tables. See the "TABLES" section for more information.

       bq  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.

       h1, h2, h3, h4, h5, h6
           Headline signatures that produce "<h1>", etc. tags.  You can adjust the relative
           output of these using the head_offset attribute.

           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.

       dl  A "dl" signature is short for "definition list". See the "LISTS" section for more

       fn  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.

       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:

       "{style rule}"
           A CSS style rule. Style rules can span multiple lines.

           A language identifier (for a "lang" attribute).

       "(class)" or "(#id)" or "(class#id)"
           For CSS class and id attributes.

       ">", "<", "=", "<>"
           Modifier characters for alignment. Right-justification, left-justification, centered,
           and full-justification.

       "(" (one or more)
           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.

       ")" (one or more)
           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.

       "|filter|" or "|filter|filter|filter|"
           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.

   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:

           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.

       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.

       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:

           p. Regular paragraph

           Escaped portion -- will not be formatted
           by Textile at all

           p. Back to normal.

       You can also use this technique within a Textile block, temporarily disabling the inline
       formatting functions:

           p. This is ==*a test*== of escaping.

   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:

           Translates into <strong>strong</strong>.

           Translates into <em>emphasis</em>.

           Translates into <b>bold</b>.

           Translates into <i>italics</i>.

           Translates into <big>bigger</big>.

           Translates into: <small>smaller</small>.

       "-deleted text-"
           Translates into <del>deleted text</del>.

       "+inserted text+"
           Translates into <ins>inserted text</ins>.

           Translates into <sup>superscript</sup>.

           Translates into <sub>subscript</sub>.

           Translates into <span>span</span>.

           Translates into <code>code</code>. Note that within a "@...@" section, < and > are
           translated into HTML entities automatically.

       Inline formatting operators accept the following modifiers:

       "{style rule}"
           A CSS style rule.

           A language identifier (for a "lang" attribute).

       "(class)" or "(#id)" or "(class#id)"
           For CSS class and id attributes.


           Textile is *way* cool.

           Textile is *_way_* cool.

       Now this won't work, because the formatting characters need whitespace before and after to
       be properly recognized.

           Textile is way c*oo*l.

       However, you can supply braces or brackets to further clarify that you want to format, so
       this would work:

           Textile is way c[*oo*]l.

       You can create footnotes like this:

           And then he went on a long trip[1].

       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:

           And then he went on a long
           trip<sup class="footnote"><a href="#fn1">1</a></sup>

       To supply the content of the footnote, place it at the end of your document using a "fn"
       block signature:

           fn1. And there was much rejoicing.

       Which creates a paragraph that looks like this:

           <p class="footnote" id="fn1"><sup>1</sup> And there was
           much rejoicing.</p>

       Textile defines a shorthand for formatting hyperlinks.  The format looks like this:

           "Text to display":

       In addition to this, you can add "title" text to your link:

           "Text to display (Title text)":

       The URL portion of the link supports relative paths as well as other protocols like ftp,
       mailto, news, telnet, etc.

           "E-mail me please"

       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:


       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):


       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:

           "Text to display":excom

       Once you've defined your link lookup table, you can use the identifiers any number of

       Images are identified by the following pattern:


       Image attributes may also be specified:

           !/path/to/image 10x20!

       Which will render an image 10 pixels wide and 20 pixels high.  Another way to indicate
       width and height:

           !/path/to/image 10w 20h!

       You may also redimension the image using a percentage.

           !/path/to/image 20%x40%!

       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:

           !/path/to/image 20%!

       Alt text can be given as well:

           !/path/to/image (Alt text)!

       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:

       "<" Align the image to the left (causes the image to float if CSS options are enabled).

       ">" Align the image to the right (causes the image to float if CSS options are enabled).

       "-" (dash)
           Aligns the image to the middle.

       "^" Aligns the image to the top.

       "~" (tilde)
           Aligns the image to the bottom.

       "{style rule}"
           Applies a CSS style rule to the image.

       "(class)" or "(#id)" or "(class#id)"
           Applies a CSS class and/or id to the image.

       "(" (one or more)
           Pads 1em on the left for each "(" character.

       ")" (one or more)
           Pads 1em on the right for each ")" character.

   Character Replacements
       A few simple, common symbols are automatically replaced:


       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:

           {c|} or {|c} cent sign
           {L-} or {-L} pound sign
           {Y=} or {=Y} yen sign

       Many of these macros can be guessed. For example:

           {A'} or {'A}
           {a"} or {"a}

       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:

           * one
           * two
           * three

       Multi-level lists:

           * one
           ** one A
           ** one B
           *** one B1
           * two
           ** two A
           ** two B
           * three

       Ordered lists:

           # one
           # two
           # three

       Styling lists:

           (class#id)* one
           * two
           * three

       The above sets the class and id attributes for the <ul> tag.

           *(class#id) one
           * two
           * three

       The above sets the class and id attributes for the first <li> tag.

       Definition lists:

           dl. textile:a cloth, especially one manufactured by weaving
           or knitting; a fabric
           format:the arrangement of data for storage or display.

       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).

       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:


       To the complex:

           table(fig). {color:red}_|Top|Row|
           {color:blue}|/2. Second|Row|
           |_{color:green}. Last|

       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:

       "{style rule}"
           A CSS style rule.

       "(class)" or "(#id)" or "(class#id)"
           A CSS class and/or id attribute.

       "(" (one or more)
           Adds 1em of padding to the left for each "(" character.

       ")" (one or more)
           Adds 1em of padding to the right for each ")" character.

       "<" Aligns to the left (floats to left for tables if combined with the ")" modifier).

       ">" Aligns to the right (floats to right for tables if combined with the "(" modifier).

       "=" Aligns to center (sets left, right margins to "auto" for tables).

           For cells only. Justifies text.

       "^" For rows and cells only. Aligns to the top.

       "~" (tilde)
           For rows and cells only. Aligns to the bottom.

       "_" (underscore)
           Can be applied to a table row or cell to indicate a header row or cell.

       "\2" or "\3" or "\4", etc.
           Used within cells to indicate a colspan of 2, 3, 4, etc. columns.  When you see "\",
           think "push forward".

       "/2" or "/3" or "/4", etc.
           Used within cells to indicate a rowspan or 2, 3, 4, etc. rows.  When you see "/",
           think "push downward".

       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.

   CSS Notes
       When CSS is enabled (and it is by default), CSS class names are automatically applied in
       certain situations.

       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.

       Aligning an image to the top or bottom
           "top" for top alignment, "bottom" for bottom alignment, "middle" for middle alignment.

           "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.

       Capped text
           For a series of characters that are uppercased, a span is placed around them with a
           class of "caps".

       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-- use the Textile syntax and let
       it produce the markup for you.
