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. - - -Version History ---------------- - -See the readme file for detailed release notes for this version. - - -Copyright and License ---------------------- - -PHP Markdown & Extra -Copyright (c) 2004-2009 Michel Fortin - -All rights reserved. - -Based on Markdown -Copyright (c) 2003-2006 John Gruber - -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.

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]: http://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 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/ + + +Version History +--------------- + +PHP Markdown Lib 1.4.0 (29 Nov 2013) + +* Added support for the `tel:` URL scheme in automatic links. + + + + It gets converted to this (note the `tel:` prefix becomes invisible): + + +1-111-111-1111 + +* 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: + + +* 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} + ![img](url){#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) 2004-2013 Michel Fortin + +All rights reserved. + +Based on Markdown +Copyright (c) 2003-2005 John Gruber + +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.
