-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
and
as well).
-
-For more information about Markdown's syntax, see:
-
-
-
-
-Bugs
-----
-
-To file bug reports please send email to:
-
-
-
-Please include with your report: (1) the example input; (2) the output you
-expected; (3) the output Markdown actually produced.

+PHP Markdown
+============
+
+PHP Markdown Lib 1.7.0 - 29 Oct 2016
+
+by Michel Fortin
+
+
+based on Markdown by John Gruber
+
+
+
+Introduction
+------------
+
+This is a library package that includes the PHP Markdown parser and its
+sibling PHP Markdown Extra with additional features.
+
+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 actually two things: a plain text markup syntax, and a
+software tool, originally 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.
+
+* [Full documentation of the Markdown syntax]()
+ — Daring Fireball (John Gruber)
+* [Markdown Extra syntax additions]()
+ — Michel Fortin
+
+
+Requirement
+-----------
+
+This library package requires PHP 5.3 or later.
+
+Note: The older plugin/library hybrid package for PHP Markdown and
+PHP Markdown Extra is still maintained and will work with PHP 4.0.5 and later.
+
+Before PHP 5.3.7, pcre.backtrack_limit defaults to 100 000, which is too small
+in many situations. You might need to set it to higher values. Later PHP
+releases defaults to 1 000 000, which is usually fine.
+
+
+Usage
+-----
+
+This library package is meant to be used with class autoloading. For autoloading
+to work, your project needs have setup a PSR-0-compatible autoloader. See the
+included Readme.php file for a minimal autoloader setup. (If you cannot use
+autoloading, see below.)
+
+With class autoloading in place, putting the 'Michelf' folder in your
+include path should be enough for this to work:
+
+ use \Michelf\Markdown;
+ $my_html = Markdown::defaultTransform($my_text);
+
+Markdown Extra syntax is also available the same way:
+
+ use \Michelf\MarkdownExtra;
+ $my_html = MarkdownExtra::defaultTransform($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 `transform`
+function call. This is an example with [PHP SmartyPants][psp]:
+
+ use \Michelf\Markdown, \Michelf\SmartyPants;
+ $my_html = Markdown::defaultTransform($my_text);
+ $my_html = SmartyPants::defaultTransform($my_html);
+
+All these examples are using the static `defaultTransform` static function
+found inside the parser class. If you want to customize the parser
+configuration, you can also instantiate it directly and change some
+configuration variables:
+
+ use \Michelf\MarkdownExtra;
+ $parser = new MarkdownExtra;
+ $parser->fn_id_prefix = "post22-";
+ $my_html = $parser->transform($my_text);
+
+To learn more, see the full list of [configuration variables].
+
+ [configuration variables]: https://michelf.ca/projects/php-markdown/configuration/
+
+
+### Usage without an autoloader
+
+If you cannot use class autoloading, you can still use `include` or `require`
+to access the parser. To load the `\Michelf\Markdown` parser, do it this way:
+
+ require_once 'Michelf/Markdown.inc.php';
+
+Or, if you need the `\Michelf\MarkdownExtra` parser:
+
+ require_once 'Michelf/MarkdownExtra.inc.php';
+
+While the plain `.php` files depend on autoloading to work correctly, using the
+`.inc.php` files instead will eagerly load the dependencies that would be
+loaded on demand if you were using autoloading.
+
+
+Public API and Versioning Policy
+---------------------------------
+
+Version numbers are of the form *major*.*minor*.*patch*.
+
+The public API of PHP Markdown consist of the two parser classes `Markdown`
+and `MarkdownExtra`, their constructors, the `transform` and `defaultTransform`
+functions and their configuration variables. The public API is stable for
+a given major version number. It might get additions when the minor version
+number increments.
+
+**Protected members are not considered public API.** This is unconventional
+and deserves an explanation. Incrementing the major version number every time
+the underlying implementation of something changes is going to give
+nonessential version numbers for the vast majority of people who just use the
+parser. Protected members are meant to create parser subclasses that behave in
+different ways. Very few people create parser subclasses. I don't want to
+discourage it by making everything private, but at the same time I can't
+guarantee any stable hook between versions if you use protected members.
+
+**Syntax changes** will increment the minor number for new features, and the
+patch number for small corrections. A *new feature* is something that needs a
+change in the syntax documentation. Note that since PHP Markdown Lib includes
+two parsers, a syntax change for either of them will increment the minor
+number. Also note that there is nothing perfectly backward-compatible with the
+Markdown syntax: all inputs are always valid, so new features always replace
+something that was previously legal, although generally nonsensical to do.
+
+
+Bugs
+----
+
+To file bug reports please send email to:
+
+
+Please include with your report: (1) the example input; (2) the output you
+expected; (3) the output PHP Markdown actually produced.
+
+If you have a problem where Markdown gives you an empty result, first check
+that the backtrack limit is not too low by running `php --info | grep pcre`.
+See Installation and Requirement above for details.
+
+
+Development and Testing
+-----------------------
+
+Pull requests for fixing bugs are welcome. Proposed new features are
+going to be meticulously reviewed -- taking into account backward compatibility,
+potential side effects, and future extensibility -- before deciding on
+acceptance or rejection.
+
+If you make a pull request that includes changes to the parser please add
+tests for what is being changed to [MDTest][] and make a pull request there
+too.

+
+Version History
+---------------
+
+PHP Markdown Lib 1.7.0 (29 Oct 2016)
+
+* Added a `hard_wrap` configuration variable to make all newline characters
+ in the text become ` ` tags in the HTML output. By default, according
+ to the standard Markdown syntax these newlines are ignored unless they a
+ preceded by two spaces. Thanks to Jonathan Cohlmeyer for the implementation.
+
+* Improved the parsing of list items to fix problematic cases that came to
+ light with the addition of `hard_wrap`. This should have no effect on the
+ output except span-level list items that ended with two spaces (and thus
+ ended with a line break).
+
+* Added a `code_span_content_func` configuration variable which takes a
+ function that will convert the content of the code span to HTML. This can
+ be useful to implement syntax highlighting. Although contrary to its
+ code block equivalent, there is no syntax for specifying a language.
+ Credits to styxit for the implementation.
+
+* Fixed a Markdwon Extra issue where two-space-at-end-of-line hard breaks
+ wouldn't work inside of HTML block elements such as `
`
+ where the element expects only span-level content.
+
+* In the parser code, switched to PHPDoc comment format. Thanks to
+ Robbie Averill for the help.
+
+
+PHP Markdown Lib 1.6.0 (23 Dec 2015)
+
+Note: this version was incorrectly released as 1.5.1 on Dec 22, a number
+that contradicted the versioning policy.
+
+* For fenced code blocks in Markdown Extra, can now set a class name for the
+ code block's language before the special attribute block. Previously, this
+ class name was only allowed in the absence of the special attribute block.
+
+* Added a `code_block_content_func` configuration variable which takes a
+ function that will convert the content of the code block to HTML. This is
+ most useful for syntax highlighting. For fenced code blocks in Markdown
+ Extra, the function has access to the language class name (the one outside
+ of the special attribute block). Credits to Mario Konrad for providing the
+ implementation.
+
+* The curled arrow character for the backlink in footnotes is now followed
+ by a Unicode variant selector to prevent it from being displayed in emoji
+ form on iOS.
+
+ Note that in older browsers the variant selector is often interpreted as a
+ separate character, making it visible after the arrow. So there is now a
+ also a `fn_backlink_html` configuration variable that can be used to set
+ the link text to something else. Credits to Dana for providing the
+ implementation.
+
+* Fixed an issue in MarkdownExtra where long header lines followed by a
+ special attribute block would hit the backtrack limit an cause an empty
+ string to be returned.
+
+
+PHP Markdown Lib 1.5.0 (1 Mar 2015)
+
+* Added the ability start ordered lists with a number different from 1 and
+ and have that reflected in the HTML output. This can be enabled with
+ the `enhanced_ordered_lists` configuration variable for the Markdown
+ parser; it is enabled by default for Markdown Extra.
+ Credits to Matt Gorle for providing the implementation.
+
+* Added the ability to insert custom HTML attributes with simple values
+ everywhere an extra attribute block is allowed (links, images, headers).
+ The value must be unquoted, cannot contains spaces and is limited to
+ alphanumeric ASCII characters.
+ Credits to Peter Droogmans for providing the implementation.
+
+* Added a `header_id_func` configuration variable which takes a function
+ that can generate an `id` attribute value from the header text.
+ Credits to Evert Pot for providing the implementation.
+
+* Added a `url_filter_func` configuration variable which takes a function
+ that can rewrite any link or image URL to something different.
+
+
+PHP Markdown Lib 1.4.1 (4 May 2014)
+
+* The HTML block parser will now treat `` as a block-level element
+ (as it should) and no longer wrap it in `
` or parse it's content with
+ the as Markdown syntax (although with Extra you can use `markdown="1"`
+ if you wish to use the Markdown syntax inside it).
+
+* The content of `
![\"$alt_text\"";](\"$url\")
titles[$link_id])) {
+ $title = $this->titles[$link_id];
+ $title = $this->encodeAttribute($title);
+ $result .= " title=\"$title\"";
+ }
+ $result .= $this->empty_element_suffix;
+ $result = $this->hashPart($result);
+ } else {
+ // If there's no such link ID, leave intact:
+ $result = $whole_match;

+
+ return $result;

+ * @param array $matches
