Provide markdown conversion (based on Michel Fortin work) to your Symfony2 projects.

INSTALLATION

Symfony 2.0) Add the following entry to deps the run php bin/vendors install.

[KnpMarkdownBundle]
    git=https://github.com/KnpLabs/KnpMarkdownBundle
    target=/bundles/Knp/Bundle/MarkdownBundle

[dflydev-markdown]
   git=https://github.com/dflydev/dflydev-markdown
   target=dflydev-markdown

And register namespace in app/autoload.php

$loader->registerNamespaces(array(
    // ...
    'dflydev' => __DIR__.'/../vendor/dflydev-markdown/src',
    'Knp'     => __DIR__.'/../vendor/bundles',
));

Symfony 2.1) Add KnpMarkdownBundle to your composer.json

{
    "require": {
        "knplabs/knp-markdown-bundle": "1.2.*@dev"
    }
}

Symfony 2.0 & 2.1) Register the bundle in app/AppKernel.php

$bundles = array(
    // ...
    new Knp\Bundle\MarkdownBundle\KnpMarkdownBundle(),
);

USAGE

// Use the service
$html = $this->container->get('markdown.parser')->transformMarkdown($text);

// Use the helper with default parser
echo $view['markdown']->transform($text);

// Use the helper and a select specific parser
echo $view['markdown']->transform($text, $parserName);

If you have enabled the Twig markdown filter, you can use the following in your Twig templates:

{# Use default parser #}
{{ my_data|markdown }}

{# Or select specific parser #}
{{ my_data|markdown('parserName') }}

Change the parser implementation

Create a service implementing Knp\Bundle\MarkdownBundle\MarkdownParserInterface,
then configure the bundle to use it:

knp_markdown:
    parser:
        service: my.markdown.parser

Alternatively if you are using the markdown.parser.sundown there are
options for enabling sundown extensions and render flags, see the
default Configuration with:

php app/console config:dump-reference knp_markdown

This bundle comes with 5 parser services, 4 based on the same algorithm
but providing different levels of compliance to the markdown specification,
and one which is uses the php sundown extension:

- markdown.parser.max       // fully compliant = slower (default implementation)
- markdown.parser.medium    // expensive and uncommon features dropped
- markdown.parser.light     // expensive features dropped
- markdown.parser.min       // most features dropped = faster
- markdown.parser.sundown   // faster and fully compliant (recommended)

markdown.parser.sundown requires the php sundown extension.

For more details, see the implementations in Parser/Preset.

TEST

phpunit -c myapp vendor/bundles/Knp/Bundle/MarkdownBundle
