Introduction
MaglMarkdown is a ZF2 module that adds a View Helper to transform Markdown. To change between different renderers have a look at the config section
You can use one of the following parsers for your Markdown:
- The PHP-Markdown parser from Michel Fortin
- The PHP-MarkdownExtra parser from Michel Fortin (this is the default)
- The Parsedown parser from Emanuil Rusev
- The Parsedown-Extra parser from Emanuil Rusev
- Github Markdown Api
- you should provide an access_token within the config, to avoid hitting the rate_limit too soon
- it's highly recommended to enable caching if you use the Github Api because of the mentioned rate_limit and to boost performance
- The PHP League's CommonMark implementation
Installation
You can install the module with composer by adding the following "require" to your composer.json
{ "require": { "maglnet/magl-markdown": "~1.1" } }
after that you need to run
$ php composer.phar update
and enable the module within your application.config.php
array( 'modules' => array( 'Application', 'MaglMarkdown', ), );
Usage
View Helper
Simply use it within your Views like this
$this->markdown('Yes, **this** is *Markdown*!');
Service Manager
You can get the MarkdownService through the Service Manager, to use
the render()
method wherever you like within you zf2 application.
MarkdownService
automatically uses caching if it has been enabled within the
config.
/* @var $markdownService MaglMarkdown\Service\Markdown */ $markdownService = $serviceManager->get('MaglMarkdown\MarkdownService'); $html = $markdownService->render('Yes, **this** is *Markdown*!');
You can also get a MarkdownAdapter through the Service Manager and use
transformText()
to get your Markdown rendered to HTML.
This is NOT recommended anymore. Use the above mentioned MarkdownService
instead
because it can use the provided caching mechanism.
/* @var $markdownAdapter MaglMarkdown\Adapter\MarkdownAdapterInterface */ $markdownAdapter = $serviceManager->get('MaglMarkdown\MarkdownAdapter'); $html = $markdownAdapter->transformText('Yes, **this** is *Markdown*!');
Security warning:
You should be aware, that your markdown could contain insecure content (e.g. user generated content).
So use something like HTMLPurifier to sanitize your output.
Configuration
Copy the provided config file config/maglmarkdown.local.php
to your
autoloading directory YourZF2Application/config/autoload/maglmarkdown.local.php
and adjust it to your needs.
By default PHP-MarkdownExtra parser by Michel Fortin is used.
Cache
By default, caching is disabled.
Set cache_enabled
to true
within config/maglmarkdown.local.php
to enable the caching.
Caching could be very helpful if you have large markdown files/texts or if you're using an Adapter
that relies on third-party APIs that either are rate limited or take a long time to render.
A simple filesystem cache is configured by default, but feel free to configure your own adapter.
Adding own parsers
It is possible to add your own parser implementation.
All you have to do, is to write a class that implements the MaglMarkdown\Adapter\MarkdownAdapterInterface
interface
and make it available through the service manager.
After that override the alias MaglMarkdown\MarkdownAdapter
to point to your custom adapter.
MaglMarkdown will then use this class to transform the Markdown.
array( 'aliases' => array( 'MaglMarkdown\MarkdownAdapter' => 'Your\Own\MarkdownAdapter', //needs to implement MaglMarkdown\Adapter\MarkdownAdapterInterface ), )
Events
The markdown service triggers two events you can listen to:
markdown.render.pre
before rendering (with the markdown text as parameter)markdown.render.post
after rendering (with the rendered markdown as parameter)
These events are currently used for the integrated caching feature only, but do whatever you like with these events.
