-PHP Markdown Extra
-==================
-
-Version 1.2.3 - Wed 31 Dec 2008
-
-by Michel Fortin
-<http://www.michelf.com/>
-
-Additional features and fixes by Henrik Paul
-<http://github.com/wolfie/php-markdown/tree/extra>
-
-based on Markdown by John Gruber
-<http://daringfireball.net/>
-
-
-Introduction
-------------
-
-This is a special version of PHP Markdown with extra features. See
-<http://www.michelf.com/projects/php-markdown/extra/> for details.
-
-Markdown is a text-to-HTML conversion tool for web writers. Markdown
-allows you to write using an easy-to-read, easy-to-write plain text
-format, then convert it to structurally valid XHTML (or HTML).
-
-"Markdown" is two things: a plain text markup syntax, and a software
-tool, written in Perl, that converts the plain text markup to HTML.
-PHP Markdown is a port to PHP of the original Markdown program by
-John Gruber.
-
-PHP Markdown can work as a plug-in for WordPress and bBlog, as a
-modifier for the Smarty templating engine, or as a remplacement for
-textile formatting in any software that support textile.
-
-Full documentation of Markdown's syntax is available on John's
-Markdown page: <http://daringfireball.net/projects/markdown/>
-
-
-Installation and Requirement
-----------------------------
-
-PHP Markdown requires PHP version 4.0.5 or later.
-
-
-### WordPress ###
-
-PHP Markdown works with [WordPress][wp], version 1.2 or later.
-
- [wp]: http://wordpress.org/
-
-1. To use PHP Markdown with WordPress, place the "makrdown.php" file
- in the "plugins" folder. This folder is located inside
- "wp-content" at the root of your site:
-
- (site home)/wp-content/plugins/
-
-2. Activate the plugin with the administrative interface of
- WordPress. In the "Plugins" section you will now find Markdown.
- To activate the plugin, click on the "Activate" button on the
- same line than Markdown. Your entries will now be formatted by
- PHP Markdown.
-
-3. To post Markdown content, you'll first have to disable the
- "visual" editor in the User section of WordPress.
-
-You can configure PHP Markdown to not apply to the comments on your
-WordPress weblog. See the "Configuration" section below.
-
-It is not possible at this time to apply a different set of
-filters to different entries. All your entries will be formated by
-PHP Markdown. This is a limitation of WordPress. If your old entries
-are written in HTML (as opposed to another formatting syntax, like
-Textile), they'll probably stay fine after installing Markdown.
-
-
-### bBlog ###
-
-PHP Markdown also works with [bBlog][bb].
-
- [bb]: http://www.bblog.com/
-
-To use PHP Markdown with bBlog, rename "markdown.php" to
-"modifier.markdown.php" and place the file in the "bBlog_plugins"
-folder. This folder is located inside the "bblog" directory of
-your site, like this:
-
- (site home)/bblog/bBlog_plugins/modifier.markdown.php
-
-Select "Markdown" as the "Entry Modifier" when you post a new
-entry. This setting will only apply to the entry you are editing.
-
-
-### Replacing Textile in TextPattern ###
-
-[TextPattern][tp] use [Textile][tx] to format your text. You can
-replace Textile by Markdown in TextPattern without having to change
-any code by using the *Texitle Compatibility Mode*. This may work
-with other software that expect Textile too.
-
- [tx]: http://www.textism.com/tools/textile/
- [tp]: http://www.textpattern.com/
-
-1. Rename the "markdown.php" file to "classTextile.php". This will
- make PHP Markdown behave as if it was the actual Textile parser.
-
-2. Replace the "classTextile.php" file TextPattern installed in your
- web directory. It can be found in the "lib" directory:
-
- (site home)/textpattern/lib/
-
-Contrary to Textile, Markdown does not convert quotes to curly ones
-and does not convert multiple hyphens (`--` and `---`) into en- and
-em-dashes. If you use PHP Markdown in Textile Compatibility Mode, you
-can solve this problem by installing the "smartypants.php" file from
-[PHP SmartyPants][psp] beside the "classTextile.php" file. The Textile
-Compatibility Mode function will use SmartyPants automatically without
-further modification.
-
- [psp]: http://www.michelf.com/projects/php-smartypants/
-
-
-### In Your Own Programs ###
-
-You can use PHP Markdown easily in your current PHP program. Simply
-include the file and then call the Markdown function on the text you
-want to convert:
-
- include_once "markdown.php";
- $my_html = Markdown($my_text);
-
-If you wish to use PHP Markdown with another text filter function
-built to parse HTML, you should filter the text *after* the Markdown
-function call. This is an example with [PHP SmartyPants][psp]:
-
- $my_html = SmartyPants(Markdown($my_text));
-
-
-### With Smarty ###
-
-If your program use the [Smarty][sm] template engine, PHP Markdown
-can now be used as a modifier for your templates. Rename "markdown.php"
-to "modifier.markdown.php" and put it in your smarty plugins folder.
-
- [sm]: http://smarty.php.net/
-
-If you are using MovableType 3.1 or later, the Smarty plugin folder is
-located at `(MT CGI root)/php/extlib/smarty/plugins`. This will allow
-Markdown to work on dynamic pages.
-
-
-### Updating Markdown in Other Programs ###
-
-Many web applications now ship with PHP Markdown, or have plugins to
-perform the conversion to HTML. You can update PHP Markdown -- or
-replace it with PHP Markdown Extra -- in many of these programs by
-swapping the old "markdown.php" file for the new one.
-
-Here is a short non-exhaustive list of some programs and where they
-hide the "markdown.php" file.
-
-| Program | Path to Markdown
-| ------- | ----------------
-| [Pivot][] | `(site home)/pivot/includes/markdown/`
-
-If you're unsure if you can do this with your application, ask the
-developer, or wait for the developer to update his application or
-plugin with the new version of PHP Markdown.
-
- [Pivot]: http://pivotlog.net/
-
-
-Configuration
--------------
-
-By default, PHP Markdown produces XHTML output for tags with empty
-elements. E.g.:
-
- <br />
-
-Markdown can be configured to produce HTML-style tags; e.g.:
-
- <br>
-
-To do this, you must edit the "MARKDOWN_EMPTY_ELEMENT_SUFFIX"
-definition below the "Global default settings" header at the start of
-the "markdown.php" file.
-
-
-### WordPress-Specific Settings ###
-
-By default, the Markdown plugin applies to both posts and comments on
-your WordPress weblog. To deactivate one or the other, edit the
-`MARKDOWN_WP_POSTS` or `MARKDOWN_WP_COMMENTS` definitions under the
-"WordPress settings" header at the start of the "markdown.php" file.
-
-
-Bugs
-----
-
-To file bug reports please send email to:
-<michel.fortin@michelf.com>
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output PHP Markdown actually produced.
-
-
-Version History
----------------
-
-Extra 1.2.3 (31 Dec 2008):
-
-* In WordPress pages featuring more than one post, footnote id prefixes are
- now automatically applied with the current post ID to avoid clashes
- between footnotes belonging to different posts.
-
-* Fix for a bug introduced in Extra 1.2 where block-level HTML tags where
- not detected correctly, thus the addition of erroneous `<p>` tags and
- interpretation of their content as Markdown-formatted instead of
- HTML-formatted.
-
-
-Extra 1.2.2 (21 Jun 2008):
-
-* Fixed a problem where abbreviation definitions, footnote
- definitions and link references were stripped inside
- fenced code blocks.
-
-* Fixed a bug where characters such as `"` in abbreviation
- definitions weren't properly encoded to HTML entities.
-
-* Fixed a bug where double quotes `"` were not correctly encoded
- as HTML entities when used inside a footnote reference id.
-
-
-1.0.1m (21 Jun 2008):
-
-* Lists can now have empty items.
-
-* Rewrote the emphasis and strong emphasis parser to fix some issues
- with odly placed and overlong markers.
-
-
-Extra 1.2.1 (27 May 2008):
-
-* Fixed a problem where Markdown headers and horizontal rules were
- transformed into their HTML equivalent inside fenced code blocks.
-
-
-Extra 1.2 (11 May 2008):
-
-* Added fenced code block syntax which don't require indentation
- and can start and end with blank lines. A fenced code block
- starts with a line of consecutive tilde (~) and ends on the
- next line with the same number of consecutive tilde. Here's an
- example:
-
- ~~~~~~~~~~~~
- Hello World!
- ~~~~~~~~~~~~
-
-* Rewrote parts of the HTML block parser to better accomodate
- fenced code blocks.
-
-* Footnotes may now be referenced from within another footnote.
-
-* Added programatically-settable parser property `predef_attr` for
- predefined attribute definitions.
-
-* Fixed an issue where an indented code block preceded by a blank
- line containing some other whitespace would confuse the HTML
- block parser into creating an HTML block when it should have
- been code.
-
-
-1.0.1l (11 May 2008):
-
-* Now removing the UTF-8 BOM at the start of a document, if present.
-
-* Now accepting capitalized URI schemes (such as HTTP:) in automatic
- links, such as `<HTTP://EXAMPLE.COM/>`.
-
-* Fixed a problem where `<hr@example.com>` was seen as a horizontal
- rule instead of an automatic link.
-
-* Fixed an issue where some characters in Markdown-generated HTML
- attributes weren't properly escaped with entities.
-
-* Fix for code blocks as first element of a list item. Previously,
- this didn't create any code block for item 2:
-
- * Item 1 (regular paragraph)
-
- * Item 2 (code block)
-
-* A code block starting on the second line of a document wasn't seen
- as a code block. This has been fixed.
-
-* Added programatically-settable parser properties `predef_urls` and
- `predef_titles` for predefined URLs and titles for reference-style
- links. To use this, your PHP code must call the parser this way:
-
- $parser = new Markdwon_Parser;
- $parser->predef_urls = array('linkref' => 'http://example.com');
- $html = $parser->transform($text);
-
- You can then use the URL as a normal link reference:
-
- [my link][linkref]
- [my link][linkRef]
-
- Reference names in the parser properties *must* be lowercase.
- Reference names in the Markdown source may have any case.
-
-* Added `setup` and `teardown` methods which can be used by subclassers
- as hook points to arrange the state of some parser variables before and
- after parsing.
-
-
-Extra 1.1.7 (26 Sep 2007):
-
-1.0.1k (26 Sep 2007):
-
-* Fixed a problem introduced in 1.0.1i where three or more identical
- uppercase letters, as well as a few other symbols, would trigger
- a horizontal line.
-
-
-Extra 1.1.6 (4 Sep 2007):
-
-1.0.1j (4 Sep 2007):
-
-* Fixed a problem introduced in 1.0.1i where the closing `code` and
- `pre` tags at the end of a code block were appearing in the wrong
- order.
-
-* Overriding configuration settings by defining constants from an
- external before markdown.php is included is now possible without
- producing a PHP warning.
-
-
-Extra 1.1.5 (31 Aug 2007):
-
-1.0.1i (31 Aug 2007):
-
-* Fixed a problem where an escaped backslash before a code span
- would prevent the code span from being created. This should now
- work as expected:
-
- Litteral backslash: \\`code span`
-
-* Overall speed improvements, especially with long documents.
-
-
-Extra 1.1.4 (3 Aug 2007):
-
-1.0.1h (3 Aug 2007):
-
-* Added two properties (`no_markup` and `no_entities`) to the parser
- allowing HTML tags and entities to be disabled.
-
-* Fix for a problem introduced in 1.0.1g where posting comments in
- WordPress would trigger PHP warnings and cause some markup to be
- incorrectly filtered by the kses filter in WordPress.
-
-
-Extra 1.1.3 (3 Jul 2007):
-
-* Fixed a performance problem when parsing some invalid HTML as an HTML
- block which was resulting in too much recusion and a segmentation fault
- for long documents.
-
-* The markdown="" attribute now accepts unquoted values.
-
-* Fixed an issue where underscore-emphasis didn't work when applied on the
- first or the last word of an element having the markdown="1" or
- markdown="span" attribute set unless there was some surrounding whitespace.
- This didn't work:
-
- <p markdown="1">_Hello_ _world_</p>
-
- Now it does produce emphasis as expected.
-
-* Fixed an issue preventing footnotes from working when the parser's
- footnote id prefix variable (fn_id_prefix) is not empty.
-
-* Fixed a performance problem where the regular expression for strong
- emphasis introduced in version 1.1 could sometime be long to process,
- give slightly wrong results, and in some circumstances could remove
- entirely the content for a whole paragraph.
-
-* Fixed an issue were abbreviations tags could be incorrectly added
- inside URLs and title of links.
-
-* Placing footnote markers inside a link, resulting in two nested links, is
- no longer allowed.
-
-
-1.0.1g (3 Jul 2007):
-
-* Fix for PHP 5 compiled without the mbstring module. Previous fix to
- calculate the length of UTF-8 strings in `detab` when `mb_strlen` is
- not available was only working with PHP 4.
-
-* Fixed a problem with WordPress 2.x where full-content posts in RSS feeds
- were not processed correctly by Markdown.
-
-* Now supports URLs containing literal parentheses for inline links
- and images, such as:
-
- [WIMP](http://en.wikipedia.org/wiki/WIMP_(computing))
-
- Such parentheses may be arbitrarily nested, but must be
- balanced. Unbalenced parentheses are allowed however when the URL
- when escaped or when the URL is enclosed in angle brakets `<>`.
-
-* Fixed a performance problem where the regular expression for strong
- emphasis introduced in version 1.0.1d could sometime be long to process,
- give slightly wrong results, and in some circumstances could remove
- entirely the content for a whole paragraph.
-
-* Some change in version 1.0.1d made possible the incorrect nesting of
- anchors within each other. This is now fixed.
-
-* Fixed a rare issue where certain MD5 hashes in the content could
- be changed to their corresponding text. For instance, this:
-
- The MD5 value for "+" is "26b17225b626fb9238849fd60eabdf60".
-
- was incorrectly changed to this in previous versions of PHP Markdown:
-
- <p>The MD5 value for "+" is "+".</p>
-
-* Now convert escaped characters to their numeric character
- references equivalent.
-
- This fix an integration issue with SmartyPants and backslash escapes.
- Since Markdown and SmartyPants have some escapable characters in common,
- it was sometime necessary to escape them twice. Previously, two
- backslashes were sometime required to prevent Markdown from "eating" the
- backslash before SmartyPants sees it:
-
- Here are two hyphens: \\--
-
- Now, only one backslash will do:
-
- Here are two hyphens: \--
-
-
-Extra 1.1.2 (7 Feb 2007)
-
-* Fixed an issue where headers preceded too closely by a paragraph
- (with no blank line separating them) where put inside the paragraph.
-
-* Added the missing TextileRestricted method that was added to regular
- PHP Markdown since 1.0.1d but which I forgot to add to Extra.
-
-
-1.0.1f (7 Feb 2007):
-
-* Fixed an issue with WordPress where manually-entered excerpts, but
- not the auto-generated ones, would contain nested paragraphs.
-
-* Fixed an issue introduced in 1.0.1d where headers and blockquotes
- preceded too closely by a paragraph (not separated by a blank line)
- where incorrectly put inside the paragraph.
-
-* Fixed an issue introduced in 1.0.1d in the tokenizeHTML method where
- two consecutive code spans would be merged into one when together they
- form a valid tag in a multiline paragraph.
-
-* Fixed an long-prevailing issue where blank lines in code blocks would
- be doubled when the code block is in a list item.
-
- This was due to the list processing functions relying on artificially
- doubled blank lines to correctly determine when list items should
- contain block-level content. The list item processing model was thus
- changed to avoid the need for double blank lines.
-
-* Fixed an issue with `<% asp-style %>` instructions used as inline
- content where the opening `<` was encoded as `&lt;`.
-
-* Fixed a parse error occuring when PHP is configured to accept
- ASP-style delimiters as boundaries for PHP scripts.
-
-* Fixed a bug introduced in 1.0.1d where underscores in automatic links
- got swapped with emphasis tags.
-
-
-Extra 1.1.1 (28 Dec 2006)
-
-* Fixed a problem where whitespace at the end of the line of an atx-style
- header would cause tailing `#` to appear as part of the header's content.
- This was caused by a small error in the regex that handles the definition
- for the id attribute in PHP Markdown Extra.
-
-* Fixed a problem where empty abbreviations definitions would eat the
- following line as its definition.
-
-* Fixed an issue with calling the Markdown parser repetitivly with text
- containing footnotes. The footnote hashes were not reinitialized properly.
-
-
-1.0.1e (28 Dec 2006)
-
-* Added support for internationalized domain names for email addresses in
- automatic link. Improved the speed at which email addresses are converted
- to entities. Thanks to Milian Wolff for his optimisations.
-
-* Made deterministic the conversion to entities of email addresses in
- automatic links. This means that a given email address will always be
- encoded the same way.
-
-* PHP Markdown will now use its own function to calculate the length of an
- UTF-8 string in `detab` when `mb_strlen` is not available instead of
- giving a fatal error.
-
-
-Extra 1.1 (1 Dec 2006)
-
-* Added a syntax for footnotes.
-
-* Added an experimental syntax to define abbreviations.
-
-
-1.0.1d (1 Dec 2006)
-
-* Fixed a bug where inline images always had an empty title attribute. The
- title attribute is now present only when explicitly defined.
-
-* Link references definitions can now have an empty title, previously if the
- title was defined but left empty the link definition was ignored. This can
- be useful if you want an empty title attribute in images to hide the
- tooltip in Internet Explorer.
-
-* Made `detab` aware of UTF-8 characters. UTF-8 multi-byte sequences are now
- correctly mapped to one character instead of the number of bytes.
-
-* Fixed a small bug with WordPress where WordPress' default filter `wpautop`
- was not properly deactivated on comment text, resulting in hard line breaks
- where Markdown do not prescribes them.
-
-* Added a `TextileRestrited` method to the textile compatibility mode. There
- is no restriction however, as Markdown does not have a restricted mode at
- this point. This should make PHP Markdown work again in the latest
- versions of TextPattern.
-
-* Converted PHP Markdown to a object-oriented design.
-
-* Changed span and block gamut methods so that they loop over a
- customizable list of methods. This makes subclassing the parser a more
- interesting option for creating syntax extensions.
-
-* Also added a "document" gamut loop which can be used to hook document-level
- methods (like for striping link definitions).
-
-* Changed all methods which were inserting HTML code so that they now return
- a hashed representation of the code. New methods `hashSpan` and `hashBlock`
- are used to hash respectivly span- and block-level generated content. This
- has a couple of significant effects:
-
- 1. It prevents invalid nesting of Markdown-generated elements which
- could occur occuring with constructs like `*something [link*][1]`.
- 2. It prevents problems occuring with deeply nested lists on which
- paragraphs were ill-formed.
- 3. It removes the need to call `hashHTMLBlocks` twice during the the
- block gamut.
-
- Hashes are turned back to HTML prior output.
-
-* Made the block-level HTML parser smarter using a specially-crafted regular
- expression capable of handling nested tags.
-
-* Solved backtick issues in tag attributes by rewriting the HTML tokenizer to
- be aware of code spans. All these lines should work correctly now:
-
- <span attr='`ticks`'>bar</span>
- <span attr='``double ticks``'>bar</span>
- `<test a="` content of attribute `">`
-
-* Changed the parsing of HTML comments to match simply from `<!--` to `-->`
- instead using of the more complicated SGML-style rule with paired `--`.
- This is how most browsers parse comments and how XML defines them too.
-
-* `<address>` has been added to the list of block-level elements and is now
- treated as an HTML block instead of being wrapped within paragraph tags.
-
-* Now only trim trailing newlines from code blocks, instead of trimming
- all trailing whitespace characters.
-
-* Fixed bug where this:
-
- [text](http://m.com "title" )
-
- wasn't working as expected, because the parser wasn't allowing for spaces
- before the closing paren.
-
-* Filthy hack to support markdown='1' in div tags.
-
-* _DoAutoLinks() now supports the 'dict://' URL scheme.
-
-* PHP- and ASP-style processor instructions are now protected as
- raw HTML blocks.
-
- <? ... ?>
- <% ... %>
-
-* Fix for escaped backticks still triggering code spans:
-
- There are two raw backticks here: \` and here: \`, not a code span
-
-
-Extra 1.0 - 5 September 2005
-
-* Added support for setting the id attributes for headers like this:
-
- Header 1 {#header1}
- ========
-
- ## Header 2 ## {#header2}
-
- This only work only for headers for now.
-
-* Tables will now work correctly as the first element of a definition
- list. For example, this input:
-
- Term
-
- : Header | Header
- ------- | -------
- Cell | Cell
-
- used to produce no definition list and a table where the first
- header was named ": Header". This is now fixed.
-
-* Fix for a problem where a paragraph following a table was not
- placed between `<p>` tags.
-
-
-Extra 1.0b4 - 1 August 2005
-
-* Fixed some issues where whitespace around HTML blocks were trigging
- empty paragraph tags.
-
-* Fixed an HTML block parsing issue that would cause a block element
- following a code span or block with unmatched opening bracket to be
- placed inside a paragraph.
-
-* Removed some PHP notices that could appear when parsing definition
- lists and tables with PHP notice reporting flag set.
-
-
-Extra 1.0b3 - 29 July 2005
-
-* Definition lists now require a blank line before each term. Solves
- an ambiguity where the last line of lazy-indented definitions could
- be mistaken by PHP Markdown as a new term in the list.
-
-* Definition lists now support multiple terms per definition.
-
-* Some special tags were replaced in the output by their md5 hash
- key. Things such as this now work as expected:
-
- ## Header <?php echo $number ?> ##
-
-
-Extra 1.0b2 - 26 July 2005
-
-* Definition lists can now take two or more definitions for one term.
- This should have been the case before, but a bug prevented this
- from working right.
-
-* Fixed a problem where single column table with a pipe only at the
- end where not parsed as table. Here is such a table:
-
- | header
- | ------
- | cell
-
-* Fixed problems with empty cells in the first column of a table with
- no leading pipe, like this one:
-
- header | header
- ------ | ------
- | cell
-
-* Code spans containing pipes did not within a table. This is now
- fixed by parsing code spans before splitting rows into cells.
-
-* Added the pipe character to the backlash escape character lists.
-
-Extra 1.0b1 (25 Jun 2005)
-
-* First public release of PHP Markdown Extra.

-PHP Markdown Extra
-==================
-
-Version 1.2.3 - Wed 31 Dec 2008
-
-by Michel Fortin
-<http://www.michelf.com/>
-
-Additional features and fixes by Henrik Paul
-<http://github.com/wolfie/php-markdown/tree/extra>
-
-based on Markdown by John Gruber
-<http://daringfireball.net/>
-
-
-Introduction
-------------
-
-This is a special version of PHP Markdown with extra features. See
-<http://www.michelf.com/projects/php-markdown/extra/> for details.
-
-Markdown is a text-to-HTML conversion tool for web writers. Markdown
-allows you to write using an easy-to-read, easy-to-write plain text
-format, then convert it to structurally valid XHTML (or HTML).
-
-"Markdown" is two things: a plain text markup syntax, and a software
-tool, written in Perl, that converts the plain text markup to HTML.
-PHP Markdown is a port to PHP of the original Markdown program by
-John Gruber.
-
-PHP Markdown can work as a plug-in for WordPress and bBlog, as a
-modifier for the Smarty templating engine, or as a remplacement for
-textile formatting in any software that support textile.
-
-Full documentation of Markdown's syntax is available on John's
-Markdown page: <http://daringfireball.net/projects/markdown/>
-
-
-Installation and Requirement
-----------------------------
-
-PHP Markdown requires PHP version 4.0.5 or later.
-
-
-### WordPress ###
-
-PHP Markdown works with [WordPress][wp], version 1.2 or later.
-
- [wp]: http://wordpress.org/
-
-1. To use PHP Markdown with WordPress, place the "makrdown.php" file
- in the "plugins" folder. This folder is located inside
- "wp-content" at the root of your site:
-
- (site home)/wp-content/plugins/
-
-2. Activate the plugin with the administrative interface of
- WordPress. In the "Plugins" section you will now find Markdown.
- To activate the plugin, click on the "Activate" button on the
- same line than Markdown. Your entries will now be formatted by
- PHP Markdown.
-
-3. To post Markdown content, you'll first have to disable the
- "visual" editor in the User section of WordPress.
-
-You can configure PHP Markdown to not apply to the comments on your
-WordPress weblog. See the "Configuration" section below.
-
-It is not possible at this time to apply a different set of
-filters to different entries. All your entries will be formated by
-PHP Markdown. This is a limitation of WordPress. If your old entries
-are written in HTML (as opposed to another formatting syntax, like
-Textile), they'll probably stay fine after installing Markdown.
-
-
-### bBlog ###
-
-PHP Markdown also works with [bBlog][bb].
-
- [bb]: http://www.bblog.com/
-
-To use PHP Markdown with bBlog, rename "markdown.php" to
-"modifier.markdown.php" and place the file in the "bBlog_plugins"
-folder. This folder is located inside the "bblog" directory of
-your site, like this:
-
- (site home)/bblog/bBlog_plugins/modifier.markdown.php
-
-Select "Markdown" as the "Entry Modifier" when you post a new
-entry. This setting will only apply to the entry you are editing.
-
-
-### Replacing Textile in TextPattern ###
-
-[TextPattern][tp] use [Textile][tx] to format your text. You can
-replace Textile by Markdown in TextPattern without having to change
-any code by using the *Texitle Compatibility Mode*. This may work
-with other software that expect Textile too.
-
- [tx]: http://www.textism.com/tools/textile/
- [tp]: http://www.textpattern.com/
-
-1. Rename the "markdown.php" file to "classTextile.php". This will
- make PHP Markdown behave as if it was the actual Textile parser.
-
-2. Replace the "classTextile.php" file TextPattern installed in your
- web directory. It can be found in the "lib" directory:
-
- (site home)/textpattern/lib/
-
-Contrary to Textile, Markdown does not convert quotes to curly ones
-and does not convert multiple hyphens (`--` and `---`) into en- and
-em-dashes. If you use PHP Markdown in Textile Compatibility Mode, you
-can solve this problem by installing the "smartypants.php" file from
-[PHP SmartyPants][psp] beside the "classTextile.php" file. The Textile
-Compatibility Mode function will use SmartyPants automatically without
-further modification.
-
- [psp]: http://www.michelf.com/projects/php-smartypants/
-
-
-### In Your Own Programs ###
-
-You can use PHP Markdown easily in your current PHP program. Simply
-include the file and then call the Markdown function on the text you
-want to convert:
-
- include_once "markdown.php";
- $my_html = Markdown($my_text);
-
-If you wish to use PHP Markdown with another text filter function
-built to parse HTML, you should filter the text *after* the Markdown
-function call. This is an example with [PHP SmartyPants][psp]:
-
- $my_html = SmartyPants(Markdown($my_text));
-
-
-### With Smarty ###
-
-If your program use the [Smarty][sm] template engine, PHP Markdown
-can now be used as a modifier for your templates. Rename "markdown.php"
-to "modifier.markdown.php" and put it in your smarty plugins folder.
-
- [sm]: http://smarty.php.net/
-
-If you are using MovableType 3.1 or later, the Smarty plugin folder is
-located at `(MT CGI root)/php/extlib/smarty/plugins`. This will allow
-Markdown to work on dynamic pages.
-
-
-### Updating Markdown in Other Programs ###
-
-Many web applications now ship with PHP Markdown, or have plugins to
-perform the conversion to HTML. You can update PHP Markdown -- or
-replace it with PHP Markdown Extra -- in many of these programs by
-swapping the old "markdown.php" file for the new one.
-
-Here is a short non-exhaustive list of some programs and where they
-hide the "markdown.php" file.
-
-| Program | Path to Markdown
-| ------- | ----------------
-| [Pivot][] | `(site home)/pivot/includes/markdown/`
-
-If you're unsure if you can do this with your application, ask the
-developer, or wait for the developer to update his application or
-plugin with the new version of PHP Markdown.
-
- [Pivot]: http://pivotlog.net/
-
-
-Configuration
--------------
-
-By default, PHP Markdown produces XHTML output for tags with empty
-elements. E.g.:
-
- <br />
-
-Markdown can be configured to produce HTML-style tags; e.g.:
-
- <br>
-
-To do this, you must edit the "MARKDOWN_EMPTY_ELEMENT_SUFFIX"
-definition below the "Global default settings" header at the start of
-the "markdown.php" file.
-
-
-### WordPress-Specific Settings ###
-
-By default, the Markdown plugin applies to both posts and comments on
-your WordPress weblog. To deactivate one or the other, edit the
-`MARKDOWN_WP_POSTS` or `MARKDOWN_WP_COMMENTS` definitions under the
-"WordPress settings" header at the start of the "markdown.php" file.
-
-
-Bugs
-----
-
-To file bug reports please send email to:
-<michel.fortin@michelf.com>
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output PHP Markdown actually produced.
-
-
-Version History
----------------
-
-Extra 1.2.3 (31 Dec 2008):
-
-* In WordPress pages featuring more than one post, footnote id prefixes are
- now automatically applied with the current post ID to avoid clashes
- between footnotes belonging to different posts.
-
-* Fix for a bug introduced in Extra 1.2 where block-level HTML tags where
- not detected correctly, thus the addition of erroneous `<p>` tags and
- interpretation of their content as Markdown-formatted instead of
- HTML-formatted.
-
-
-Extra 1.2.2 (21 Jun 2008):
-
-* Fixed a problem where abbreviation definitions, footnote
- definitions and link references were stripped inside
- fenced code blocks.
-
-* Fixed a bug where characters such as `"` in abbreviation
- definitions weren't properly encoded to HTML entities.
-
-* Fixed a bug where double quotes `"` were not correctly encoded
- as HTML entities when used inside a footnote reference id.
-
-
-1.0.1m (21 Jun 2008):
-
-* Lists can now have empty items.
-
-* Rewrote the emphasis and strong emphasis parser to fix some issues
- with odly placed and overlong markers.
-
-
-Extra 1.2.1 (27 May 2008):
-
-* Fixed a problem where Markdown headers and horizontal rules were
- transformed into their HTML equivalent inside fenced code blocks.
-
-
-Extra 1.2 (11 May 2008):
-
-* Added fenced code block syntax which don't require indentation
- and can start and end with blank lines. A fenced code block
- starts with a line of consecutive tilde (~) and ends on the
- next line with the same number of consecutive tilde. Here's an
- example:
-
- ~~~~~~~~~~~~
- Hello World!
- ~~~~~~~~~~~~
-
-* Rewrote parts of the HTML block parser to better accomodate
- fenced code blocks.
-
-* Footnotes may now be referenced from within another footnote.
-
-* Added programatically-settable parser property `predef_attr` for
- predefined attribute definitions.
-
-* Fixed an issue where an indented code block preceded by a blank
- line containing some other whitespace would confuse the HTML
- block parser into creating an HTML block when it should have
- been code.
-
-
-1.0.1l (11 May 2008):
-
-* Now removing the UTF-8 BOM at the start of a document, if present.
-
-* Now accepting capitalized URI schemes (such as HTTP:) in automatic
- links, such as `<HTTP://EXAMPLE.COM/>`.
-
-* Fixed a problem where `<hr@example.com>` was seen as a horizontal
- rule instead of an automatic link.
-
-* Fixed an issue where some characters in Markdown-generated HTML
- attributes weren't properly escaped with entities.
-
-* Fix for code blocks as first element of a list item. Previously,
- this didn't create any code block for item 2:
-
- * Item 1 (regular paragraph)
-
- * Item 2 (code block)
-
-* A code block starting on the second line of a document wasn't seen
- as a code block. This has been fixed.
-
-* Added programatically-settable parser properties `predef_urls` and
- `predef_titles` for predefined URLs and titles for reference-style
- links. To use this, your PHP code must call the parser this way:
-
- $parser = new Markdwon_Parser;
- $parser->predef_urls = array('linkref' => 'http://example.com');
- $html = $parser->transform($text);
-
- You can then use the URL as a normal link reference:
-
- [my link][linkref]
- [my link][linkRef]
-
- Reference names in the parser properties *must* be lowercase.
- Reference names in the Markdown source may have any case.
-
-* Added `setup` and `teardown` methods which can be used by subclassers
- as hook points to arrange the state of some parser variables before and
- after parsing.
-
-
-Extra 1.1.7 (26 Sep 2007):
-
-1.0.1k (26 Sep 2007):
-
-* Fixed a problem introduced in 1.0.1i where three or more identical
- uppercase letters, as well as a few other symbols, would trigger
- a horizontal line.
-
-
-Extra 1.1.6 (4 Sep 2007):
-
-1.0.1j (4 Sep 2007):
-
-* Fixed a problem introduced in 1.0.1i where the closing `code` and
- `pre` tags at the end of a code block were appearing in the wrong
- order.
-
-* Overriding configuration settings by defining constants from an
- external before markdown.php is included is now possible without
- producing a PHP warning.
-
-
-Extra 1.1.5 (31 Aug 2007):
-
-1.0.1i (31 Aug 2007):
-
-* Fixed a problem where an escaped backslash before a code span
- would prevent the code span from being created. This should now
- work as expected:
-
- Litteral backslash: \\`code span`
-
-* Overall speed improvements, especially with long documents.
-
-
-Extra 1.1.4 (3 Aug 2007):
-
-1.0.1h (3 Aug 2007):
-
-* Added two properties (`no_markup` and `no_entities`) to the parser
- allowing HTML tags and entities to be disabled.
-
-* Fix for a problem introduced in 1.0.1g where posting comments in
- WordPress would trigger PHP warnings and cause some markup to be
- incorrectly filtered by the kses filter in WordPress.
-
-
-Extra 1.1.3 (3 Jul 2007):
-
-* Fixed a performance problem when parsing some invalid HTML as an HTML
- block which was resulting in too much recusion and a segmentation fault
- for long documents.
-
-* The markdown="" attribute now accepts unquoted values.
-
-* Fixed an issue where underscore-emphasis didn't work when applied on the
- first or the last word of an element having the markdown="1" or
- markdown="span" attribute set unless there was some surrounding whitespace.
- This didn't work:
-
- <p markdown="1">_Hello_ _world_</p>
-
- Now it does produce emphasis as expected.
-
-* Fixed an issue preventing footnotes from working when the parser's
- footnote id prefix variable (fn_id_prefix) is not empty.
-
-* Fixed a performance problem where the regular expression for strong
- emphasis introduced in version 1.1 could sometime be long to process,
- give slightly wrong results, and in some circumstances could remove
- entirely the content for a whole paragraph.
-
-* Fixed an issue were abbreviations tags could be incorrectly added
- inside URLs and title of links.
-
-* Placing footnote markers inside a link, resulting in two nested links, is
- no longer allowed.
-
-
-1.0.1g (3 Jul 2007):
-
-* Fix for PHP 5 compiled without the mbstring module. Previous fix to
- calculate the length of UTF-8 strings in `detab` when `mb_strlen` is
- not available was only working with PHP 4.
-
-* Fixed a problem with WordPress 2.x where full-content posts in RSS feeds
- were not processed correctly by Markdown.
-
-* Now supports URLs containing literal parentheses for inline links
- and images, such as:
-
- [WIMP](http://en.wikipedia.org/wiki/WIMP_(computing))
-
- Such parentheses may be arbitrarily nested, but must be
- balanced. Unbalenced parentheses are allowed however when the URL
- when escaped or when the URL is enclosed in angle brakets `<>`.
-
-* Fixed a performance problem where the regular expression for strong
- emphasis introduced in version 1.0.1d could sometime be long to process,
- give slightly wrong results, and in some circumstances could remove
- entirely the content for a whole paragraph.
-
-* Some change in version 1.0.1d made possible the incorrect nesting of
- anchors within each other. This is now fixed.
-
-* Fixed a rare issue where certain MD5 hashes in the content could
- be changed to their corresponding text. For instance, this:
-
- The MD5 value for "+" is "26b17225b626fb9238849fd60eabdf60".
-
- was incorrectly changed to this in previous versions of PHP Markdown:
-
- <p>The MD5 value for "+" is "+".</p>
-
-* Now convert escaped characters to their numeric character
- references equivalent.
-
- This fix an integration issue with SmartyPants and backslash escapes.
- Since Markdown and SmartyPants have some escapable characters in common,
- it was sometime necessary to escape them twice. Previously, two
- backslashes were sometime required to prevent Markdown from "eating" the
- backslash before SmartyPants sees it:
-
- Here are two hyphens: \\--
-
- Now, only one backslash will do:
-
- Here are two hyphens: \--
-
-
-Extra 1.1.2 (7 Feb 2007)
-
-* Fixed an issue where headers preceded too closely by a paragraph
- (with no blank line separating them) where put inside the paragraph.
-
-* Added the missing TextileRestricted method that was added to regular
- PHP Markdown since 1.0.1d but which I forgot to add to Extra.
-
-
-1.0.1f (7 Feb 2007):
-
-* Fixed an issue with WordPress where manually-entered excerpts, but
- not the auto-generated ones, would contain nested paragraphs.
-
-* Fixed an issue introduced in 1.0.1d where headers and blockquotes
- preceded too closely by a paragraph (not separated by a blank line)
- where incorrectly put inside the paragraph.
-
-* Fixed an issue introduced in 1.0.1d in the tokenizeHTML method where
- two consecutive code spans would be merged into one when together they
- form a valid tag in a multiline paragraph.
-
-* Fixed an long-prevailing issue where blank lines in code blocks would
- be doubled when the code block is in a list item.
-
- This was due to the list processing functions relying on artificially
- doubled blank lines to correctly determine when list items should
- contain block-level content. The list item processing model was thus
- changed to avoid the need for double blank lines.
-
-* Fixed an issue with `<% asp-style %>` instructions used as inline
- content where the opening `<` was encoded as `&lt;`.
-
-* Fixed a parse error occuring when PHP is configured to accept
- ASP-style delimiters as boundaries for PHP scripts.
-
-* Fixed a bug introduced in 1.0.1d where underscores in automatic links
- got swapped with emphasis tags.
-
-
-Extra 1.1.1 (28 Dec 2006)
-
-* Fixed a problem where whitespace at the end of the line of an atx-style
- header would cause tailing `#` to appear as part of the header's content.
- This was caused by a small error in the regex that handles the definition
- for the id attribute in PHP Markdown Extra.
-
-* Fixed a problem where empty abbreviations definitions would eat the
- following line as its definition.
-
-* Fixed an issue with calling the Markdown parser repetitivly with text
- containing footnotes. The footnote hashes were not reinitialized properly.
-
-
-1.0.1e (28 Dec 2006)
-
-* Added support for internationalized domain names for email addresses in
- automatic link. Improved the speed at which email addresses are converted
- to entities. Thanks to Milian Wolff for his optimisations.
-
-* Made deterministic the conversion to entities of email addresses in
- automatic links. This means that a given email address will always be
- encoded the same way.
-
-* PHP Markdown will now use its own function to calculate the length of an
- UTF-8 string in `detab` when `mb_strlen` is not available instead of
- giving a fatal error.
-
-
-Extra 1.1 (1 Dec 2006)
-
-* Added a syntax for footnotes.
-
-* Added an experimental syntax to define abbreviations.
-
-
-1.0.1d (1 Dec 2006)
-
-* Fixed a bug where inline images always had an empty title attribute. The
- title attribute is now present only when explicitly defined.
-
-* Link references definitions can now have an empty title, previously if the
- title was defined but left empty the link definition was ignored. This can
- be useful if you want an empty title attribute in images to hide the
- tooltip in Internet Explorer.
-
-* Made `detab` aware of UTF-8 characters. UTF-8 multi-byte sequences are now
- correctly mapped to one character instead of the number of bytes.
-
-* Fixed a small bug with WordPress where WordPress' default filter `wpautop`
- was not properly deactivated on comment text, resulting in hard line breaks
- where Markdown do not prescribes them.
-
-* Added a `TextileRestrited` method to the textile compatibility mode. There
- is no restriction however, as Markdown does not have a restricted mode at
- this point. This should make PHP Markdown work again in the latest
- versions of TextPattern.
-
-* Converted PHP Markdown to a object-oriented design.
-
-* Changed span and block gamut methods so that they loop over a
- customizable list of methods. This makes subclassing the parser a more
- interesting option for creating syntax extensions.
-
-* Also added a "document" gamut loop which can be used to hook document-level
- methods (like for striping link definitions).
-
-* Changed all methods which were inserting HTML code so that they now return
- a hashed representation of the code. New methods `hashSpan` and `hashBlock`
- are used to hash respectivly span- and block-level generated content. This
- has a couple of significant effects:
-
- 1. It prevents invalid nesting of Markdown-generated elements which
- could occur occuring with constructs like `*something [link*][1]`.
- 2. It prevents problems occuring with deeply nested lists on which
- paragraphs were ill-formed.
- 3. It removes the need to call `hashHTMLBlocks` twice during the the
- block gamut.
-
- Hashes are turned back to HTML prior output.
-
-* Made the block-level HTML parser smarter using a specially-crafted regular
- expression capable of handling nested tags.
-
-* Solved backtick issues in tag attributes by rewriting the HTML tokenizer to
- be aware of code spans. All these lines should work correctly now:
-
- <span attr='`ticks`'>bar</span>
- <span attr='``double ticks``'>bar</span>
- `<test a="` content of attribute `">`
-
-* Changed the parsing of HTML comments to match simply from `<!--` to `-->`
- instead using of the more complicated SGML-style rule with paired `--`.
- This is how most browsers parse comments and how XML defines them too.
-
-* `<address>` has been added to the list of block-level elements and is now
- treated as an HTML block instead of being wrapped within paragraph tags.
-
-* Now only trim trailing newlines from code blocks, instead of trimming
- all trailing whitespace characters.
-
-* Fixed bug where this:
-
- [text](http://m.com "title" )
-
- wasn't working as expected, because the parser wasn't allowing for spaces
- before the closing paren.
-
-* Filthy hack to support markdown='1' in div tags.
-
-* _DoAutoLinks() now supports the 'dict://' URL scheme.
-
-* PHP- and ASP-style processor instructions are now protected as
- raw HTML blocks.
-
- <? ... ?>
- <% ... %>
-
-* Fix for escaped backticks still triggering code spans:
-
- There are two raw backticks here: \` and here: \`, not a code span
-
-
-Extra 1.0 - 5 September 2005
-
-* Added support for setting the id attributes for headers like this:
-
- Header 1 {#header1}
- ========
-
- ## Header 2 ## {#header2}
-
- This only work only for headers for now.
-
-* Tables will now work correctly as the first element of a definition
- list. For example, this input:
-
- Term
-
- : Header | Header
- ------- | -------
- Cell | Cell
-
- used to produce no definition list and a table where the first
- header was named ": Header". This is now fixed.
-
-* Fix for a problem where a paragraph following a table was not
- placed between `<p>` tags.
-
-
-Extra 1.0b4 - 1 August 2005
-
-* Fixed some issues where whitespace around HTML blocks were trigging
- empty paragraph tags.
-
-* Fixed an HTML block parsing issue that would cause a block element
- following a code span or block with unmatched opening bracket to be
- placed inside a paragraph.
-
-* Removed some PHP notices that could appear when parsing definition
- lists and tables with PHP notice reporting flag set.
-
-
-Extra 1.0b3 - 29 July 2005
-
-* Definition lists now require a blank line before each term. Solves
- an ambiguity where the last line of lazy-indented definitions could
- be mistaken by PHP Markdown as a new term in the list.
-
-* Definition lists now support multiple terms per definition.
-
-* Some special tags were replaced in the output by their md5 hash
- key. Things such as this now work as expected:
-
- ## Header <?php echo $number ?> ##
-
-
-Extra 1.0b2 - 26 July 2005
-
-* Definition lists can now take two or more definitions for one term.
- This should have been the case before, but a bug prevented this
- from working right.
-
-* Fixed a problem where single column table with a pipe only at the
- end where not parsed as table. Here is such a table:
-
- | header
- | ------
- | cell
-
-* Fixed problems with empty cells in the first column of a table with
- no leading pipe, like this one:
-
- header | header
- ------ | ------
- | cell
-
-* Code spans containing pipes did not within a table. This is now
- fixed by parsing code spans before splitting rows into cells.
-
-* Added the pipe character to the backlash escape character lists.
-
-Extra 1.0b1 (25 Jun 2005)
-
-* First public release of PHP Markdown Extra.

-PHP Markdown Extra
-==================
-
-Description
------------
-
-This is a PHP port of the original Markdown formatter written in Perl
-by John Gruber. This special "Extra" version of PHP Markdown features
-further enhancements to the syntax for making additional constructs
-such as tables and definition list.
-
-Markdown is a text-to-HTML filter; it translates an easy-to-read /
-easy-to-write structured text format into HTML. Markdown's text format
-is most similar to that of plain text email, and supports features such
-as headers, *emphasis*, code blocks, blockquotes, and links.
-
-Markdown's syntax is designed not as a generic markup language, but
-specifically to serve as a front-end to (X)HTML. You can use span-level
-HTML tags anywhere in a Markdown document, and you can use block level
-HTML tags (like <div> and <table> as well).
-
-For more information about Markdown's syntax, see:
-
-<http://daringfireball.net/projects/markdown/>
