Yet another PHP parser for the markdown (extended) syntax.

Last Release Build Status Dependency Status Code Climate

PHP Markdown Extended is a PHP parser to transform Markdown text files or strings in HTML or other formats. This new version of a Markdown parser tries to follow the extended syntax specifications and is PHP-5.3 compliant and highly customizable.

You can use this package in PHP scripts just as usual (for PHP apps) and also like a standalone command line utility. The CLI interface is interactive with a large set of options and fully documented.

README contents:

Installation

You can use this package in your work in many ways. Please note that it requires a running PHP version of 5.3.3 minimum.

Raw PHP package

First, you can clone the GitHub repository and include it "as is" in your project:

$ git clone https://github.com/piwi/markdown-extended.git

You can also download an archive from GitHub:

$ wget --no-check-certificate https://github.com/piwi/markdown-extended/archive/master.tar.gz
$ tar -xvf master.tar.gz

Then, to use the package classes, you just need to include its bootstrapper which will register its namespaces in current runtime environment:

require_once 'path/to/package/src/bootstrap.php';

Using Composer

Another way to use the package, if you are a Composer user, is to add it to your requirements in your composer.json file:

"piwi/markdown-extended": "dev-master"

The namespace will be automatically added to the project's Composer's autoloader.

Using a standalone version

Finally, if you plan to use the parser as a single binary, you can use a PHAR archive directly, which embeds the whole source as a standalone binary (~220Kb). Its usage is the same as the bin/markdown-extended script described below.

The archive is stored in a specific phar-latest branch on the repository:

$ wget --no-check-certificate https://github.com/piwi/markdown-extended/archive/phar-latest.tar.gz
$ tar -xvf phar-latest.tar.gz
$ cd phar-latest
Locally

If you only need the archive for a local project, you can copy it where you want:

$ cp bin/markdown-extended.phar your/project/path/
$ php your/project/path/markdown-extended.phar ...
Personally

To install the binary in your user's binaries:

$ ./install.sh ~/bin false
Globally

For a complete global install, run:

$ sudo ./install.sh /usr/local

Usage

An HTML demonstration and the code documentation are available on the "dev" branch.

Usage for writers

To be compliant with the extended Markdown syntax, writers may construct their contents following the rules described at http://cheatsheet.aboutmde.org/ (all basic markdown rules are still available and valid).

For a full example and a test file, you can refer to the demo/MD_syntax.md file of the package ; the latest version can be found at http://github.com/piwi/markdown-extended/blob/dev/demo/MD_syntax.md.

Usage for developers

The source code documentation of the last stable release can also be found online at http://docs.ateliers-pierrot.fr/markdown-extended/.

The MarkdownExtended package can be simply call writing:

use \MarkdownExtended\MarkdownExtended;     // load the namespace

$options = array( /* ... */ );              // parser options, see documentation

// parse a string or a file content
$content = MarkdownExtended::parse( "my markdown string" OR 'my-markdown-file.md' , $options );

// parse a string
$content = MarkdownExtended::parseString( "my markdown string" , $options );

// parse a file content
$content = MarkdownExtended::parseSource( 'my-markdown-file.md' , $options );

This will load in $content the parsed version of your original Markdown source (file content or string).

The returned $content variable is actually a \MarkdownExtended\API\ContentInterface object but you can write it directly using:

echo $content;          // shortcut for $content->getContent()

To get the part you need from the content, write:

$content
    ->getContent()      // the full content
    ->getCharset()      // a guessed character set
    ->getTitle()        // the guessed title
    ->getBody()         // the body
    ->getMetadata()     // the metadata as array
    ->getNotes()        // the notes as array
;

You can also use the \MarkdownExtended\Parser object as a procedural non-static object (this is in fact what the static methods above really do):

// create an instance with custom options
$parser = new \MarkdownExtended\Parser( $options );

// parse a string
$content = $parser->transform( "my markdown string" );

// parse a file content
$content = $parser->transformSource( 'my-markdown-file.md' );

A more complete usage documentation is available in the package's documents (doc/DOCUMENTATION.md). You can read it online at https://github.com/piwi/markdown-extended/blob/master/doc/DOCUMENTATION.md. Its manpage version is embedded in the package running:

$ man ./man/markdown-extended.7.man

Command line usage

A command line interface is proposed with the package running:

$ ./bin/markdown-extended --help

The interface allows to parse one or more files, extract some information from sources, write the results in files and some other stuff. A large set of options are available to customize the transformation.

A complete manpage is available in the package's man/ directory and its markdown source is available in its documents (doc/MANPAGE.md). To read it, run:

$ man ./man/markdown-extended.3.man

The developer documentation is also available as a manpage running:

$ man ./man/markdown-extended.7.man

Examples of cli usage:

# transform a simple string
$ ./bin/markdown-extended "my **markdown** _extended_ string"
my <strong>markdown</strong> <em>extended</em> string

# transform a file content with output to STDOUT
$ ./bin/markdown-extended my-markdown-file.md
...

# transform a file content with output in file
$ ./bin/markdown-extended --output=my-transformed-markdown.html my-markdown-file.md
...

# generate the manpage itslef
$ ./bin/markdown-extended -f man -o man/markdown-extended.man doc/MANPAGE.md
...

Old parsers compatibility

To keep the package compatible with old versions of Markdown, an interface is embedded with the common Markdown($content) function ; to use it, just include the file src/markdown.php of the package:

require_once 'path/to/src/markdown.php';

// to get result of a string parsing:
echo Markdown($string [, $options]);

// to get result of a file content parsing:
echo MarkdownFromSource($file_name [, $options]);

This way, you may be able to change your Markdown parser without so much work and, I hope so, a better result ;)
