LinkRewriter Extension
======================

[](#linkrewriter-extension)

Summary
-------

[](#summary)

Indispensable plumbing for any hosted documentation setup. Rewrites link and image URLs after parsing so your markdown stays decoupled from your deployment URL. Rules are composable and applied in sequence: prepend a base URI, swap URLs by exact match, replace with a regex pattern, or run a custom callback. Chain as many as you need.

Installation
------------

[](#installation)

### composer require

[](#composer-require)

```
composer require alto/commonmark
```

### Registration

[](#registration)

```
use Alto\CommonMark\Extension\LinkRewriter\LinkRewriterExtension;
use League\CommonMark\Environment\Environment;

$environment = new Environment();
$environment->addExtension(new LinkRewriterExtension([
    'base_uri' => 'https://docs.example.com',
]));
```

Usage
-----

[](#usage)

No custom markdown directive is required; standard links/images are rewritten during document processing.

Configuration
-------------

[](#configuration)

- `base_uri`: prepends a base URL to relative links.
- `map`: exact URL mapping array.
- `pattern`: regex replacement pair (`pattern` + `replacement`).
- `callback`: custom callable for advanced rewriting.
