# CommonMark Extension Pygments Highlighter
2+
3+
The `PygmentsHighlighter` extension adds support for using pygments to style
4+
blocks of code in Markdown documents.
5+
6+
## Installation
7+
8+
This extension can be installed from packagist via composer:
9+
10+
```bash
11+
composer require danielescherzer/commonmark-ext-pygments-highlighter
12+
```
13+
14+
It depends on
15+
16+
* `league/commonmark` (version 2.7 or above; all lower versions have security
17+
issues)
18+
* `ramsey/pygments` (version 3.0 or above)
19+
20+
Separately (not enforced via composer) you need to have python and the pygments
21+
python library installed. The extension is currently tested against
22+
23+
* Python 3.11, 3.12, and 3.13
24+
* Pygments 2.17, 2.18, and 2.19
25+
26+
The pygments command is assumed to be at `pygmentize` (in the PATH); if this is
27+
not the case configure the correct path in the extension setup, see the
28+
configuration section below.
29+
30+
## Syntax and results
31+
32+
Sample Markdown input:
33+
34+
````markdown
35+
```php
36+
<?php
37+
class User {
38+
private int $id;
39+
private string $name;
40+
41+
public function __construct( int $id, string $name ) {
42+
$this->id = $id;
43+
$this->name = $name;
44+
}
45+
}
46+
```
47+
````
48+
49+
Result:
50+
51+
```html
52+
<div class="pygments-highlighter"><div class="highlight"><pre><span></span><span class="cp">&lt;?php</span>
53+
<span class="k">class</span> <span class="nc">User</span> <span class="p">{</span>
54+
<span class="k">private</span> <span class="nx">int</span> <span class="nv">$id</span><span class="p">;</span>
55+
<span class="k">private</span> <span class="nx">string</span> <span class="nv">$name</span><span class="p">;</span>
56+
57+
<span class="k">public</span> <span class="k">function</span> <span class="fm">__construct</span><span class="p">(</span> <span class="nx">int</span> <span class="nv">$id</span><span class="p">,</span> <span class="nx">string</span> <span class="nv">$name</span> <span class="p">)</span> <span class="p">{</span>
58+
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">id</span> <span class="o">=</span> <span class="nv">$id</span><span class="p">;</span>
59+
<span class="nv">$this</span><span class="o">-&gt;</span><span class="na">name</span> <span class="o">=</span> <span class="nv">$name</span><span class="p">;</span>
60+
<span class="p">}</span>
61+
<span class="p">}</span>
62+
</pre></div>
63+
</div>
64+
```
65+
66+
## Usage
67+
68+
Configure your `Environment` as usual and simply add an instance of the
69+
`PygmentsHighlighterExtension`:
70+
71+
```php
72+
<?php
73+
74+
use DanielEScherzer\CommonMarkPygmentsHighlighter\PygmentsHighlighterExtension;
75+
use League\CommonMark\Environment\Environment;
76+
use League\CommonMark\Extension\CommonMark\CommonMarkCoreExtension;
77+
use League\CommonMark\MarkdownConverter;
78+
79+
// These are the defaults for the extension, you can change them
80+
$config = [
81+
'pygments_highlighter' => [
82+
'pygmentize_path' => null, // Use `pygmentize` from PATH
83+
'on_exception' => 'warn',
84+
],
85+
];
86+
87+
// Configure the Environment with the desired extensions
88+
$environment = new Environment( $config );
89+
$environment->addExtension( new CommonMarkCoreExtension() );
90+
$environment->addExtension( new PygmentsHighlighterExtension() );
91+
92+
// And convert your markdown
93+
$converter = new MarkdownConverter($environment);
94+
echo $converter->convert("```php\n<?php\necho 'testing...';\n```");
95+
```
96+
97+
## Configuration
98+
99+
This extension can be configured by providing a `pygments_highlighter` array
100+
with the following options (defaults shown above):
101+
102+
### `pygmentize_path`
103+
104+
The path to the pygmentize command, or null to use the default (`pygmentize`).
105+
106+
### `on_exception`
107+
108+
If the attempt to use the pygmentize command fails, this value controls the
109+
behavior of the rendererer. By default, it is set to 'warn' - it can be:
110+
111+
* 'warn' - show a warning and render the code with the CommonMark-provided
112+
default output
113+
* 'ignore' - render the code with the CommonMark-provided default output
114+
* 'throw' - rethrow the exception with the failure details
115+
116+
## Adding styles
117+
118+
This extension just adds the various classes for the output to be made
119+
colorful, you still need to add CSS targetting the code. The `ramsey/pygments`
120+
library offers a method to get an entire stylesheet for any of the pygments
121+
built-in styles, or you can build your own styling.
122+
123+
All of the highlighted code output from this extension will be within a
124+
div with the `pygments-highlighter` class, so your CSS rules can be scoped to
125+
only elements within the `.pygments-highlighter` selector.
