An implementation of YAML Front matter for PHP. Can parse the YAML and the Markdown.

Build Status Total Downloads

Installation

Require the project with Composer:

composer require mnapoli/front-yaml

Usage

$parser = new Mni\FrontYAML\Parser();

$document = $parser->parse($str);

$yaml = $document->getYAML();
$html = $document->getContent();

If you don't want the Markdown to be parsed (maybe because it is not Markdown):

$document = $parser->parse($str, false);

Example

The following file:

---
foo: bar
---
This is **strong**.

Will give:

var_export($document->getYAML());
// array("foo" => "bar")

var_export($document->getContent());
// "<p>This is <strong>strong</strong></p>"

YAML and Markdown parsers

$parser = new Mni\FrontYAML\Parser($yamlParser, $markdownParser);

This library uses dependency injection and abstraction to allow you to provide your own YAML or Markdown parser.

interface YAMLParser
{
    public function parse($yaml);
}

FrontYAML uses by default Symfony's YAML parser.

interface MarkdownParser
{
    public function parse($markdown);
}

FrontYAML uses by default Parsedown Markdown parser.

An adapter to League CommonMark is also included (you need to require the league/commonmark though):

use \Mni\FrontYAML\Bridge\CommonMark\CommonMarkParser;

$parser = new Mni\FrontYAML\Parser(null, new CommonMarkParser());
