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](<https://daringfireball.net/projects/markdown/>) + — Daring Fireball (John Gruber) +* [Markdown Extra syntax additions](<https://michelf.ca/projects/php-markdown/extra/>) + — 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: +<michel.fortin@michelf.ca> + +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. + + [MDTest]: https://github.com/michelf/mdtest/ + + +Donations +--------- + +If you wish to make a donation that will help me devote more time to +PHP Markdown, please visit [michelf.ca/donate] or send Bitcoin to +[1HiuX34czvVPPdhXbUAsAu7pZcesniDCGH]. + + [michelf.ca/donate]: https://michelf.ca/donate/#!Thanks%20for%20PHP%20Markdown + [1HiuX34czvVPPdhXbUAsAu7pZcesniDCGH]: bitcoin:1HiuX34czvVPPdhXbUAsAu7pZcesniDCGH + + +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 `<br>` 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 `<p markdown="1">` + 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 `<figure>` as a block-level element + (as it should) and no longer wrap it in `<p>` 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 `<style>` elements will now be left alone, its content + won't be interpreted as Markdown. + +* Corrected an bug where some inline links with spaces in them would not + work even when surounded with angle brackets: + + [link](<s p a c e s>) + +* Fixed an issue where email addresses with quotes in them would not always + have the quotes escaped in the link attribute, causing broken links (and + invalid HTML). + +* Fixed the case were a link definition following a footnote definition would + be swallowed by the footnote unless it was separated by a blank line. + + +PHP Markdown Lib 1.4.0 (29 Nov 2013) + +* Added support for the `tel:` URL scheme in automatic links. + + <tel:+1-111-111-1111> + + It gets converted to this (note the `tel:` prefix becomes invisible): + + <a href="tel:+1-111-111-1111">+1-111-111-1111</a> + +* Added backtick fenced code blocks to MarkdownExtra, originally from + Github-Flavored Markdown. + +* Added an interface called MarkdownInterface implemented by both + the Markdown and MarkdownExtra parsers. You can use the interface if + you want to create a mockup parser object for unit testing. + +* For those of you who cannot use class autoloading, you can now + include `Michelf/Markdown.inc.php` or `Michelf/MarkdownExtra.inc.php` (note + the `.inc.php` extension) to automatically include other files required + by the parser. + + +PHP Markdown Lib 1.3 (11 Apr 2013) + +This is the first release of PHP Markdown Lib. This package requires PHP +version 5.3 or later and is designed to work with PSR-0 autoloading and, +optionally with Composer. Here is a list of the changes since +PHP Markdown Extra 1.2.6: + +* Plugin interface for WordPress and other systems is no longer present in + the Lib package. The classic package is still available if you need it: + <https://michelf.ca/projects/php-markdown/classic/> + +* Added `public` and `protected` protection attributes, plus a section about + what is "public API" and what isn't in the Readme file. + +* Changed HTML output for footnotes: now instead of adding `rel` and `rev` + attributes, footnotes links have the class name `footnote-ref` and + backlinks `footnote-backref`. + +* Fixed some regular expressions to make PCRE not shout warnings about POSIX + collation classes (dependent on your version of PCRE). + +* Added optional class and id attributes to images and links using the same + syntax as for headers: + + [link](url){#id .class} + {#id .class} + + It work too for reference-style links and images. In this case you need + to put those attributes at the reference definition: + + [link][linkref] or [linkref] + ![img][linkref] + + [linkref]: url "optional title" {#id .class} + +* Fixed a PHP notice message triggered when some table column separator + markers are missing on the separator line below column headers. + +* Fixed a small mistake that could cause the parser to retain an invalid + state related to parsing links across multiple runs. This was never + observed (that I know of), but it's still worth fixing. + + +Copyright and License +--------------------- + +PHP Markdown Lib +Copyright (c) 2004-2016 Michel Fortin +<https://michelf.ca/> +All rights reserved. + +Based on Markdown +Copyright (c) 2003-2005 John Gruber +<https://daringfireball.net/> +All rights reserved. + +Redistribution and use in source and binary forms, with or without +modification, are permitted provided that the following conditions are +met: + +* Redistributions of source code must retain the above copyright + notice, this list of conditions and the following disclaimer. + +* Redistributions in binary form must reproduce the above copyright + notice, this list of conditions and the following disclaimer in the + documentation and/or other materials provided with the + distribution. + +* Neither the name "Markdown" nor the names of its contributors may + be used to endorse or promote products derived from this software + without specific prior written permission. + +This software is provided by the copyright holders and contributors "as +is" and any express or implied warranties, including, but not limited +to, the implied warranties of merchantability and fitness for a +particular purpose are disclaimed.
