README

obsidian-commonmark-extension is a custom extension for the CommonMark markdown parser that adds a new inline element and renderer for displaying images with a configurable base URL. A new inline element and parser for obsidian style links and anchors

Installation

You can install the extension using Composer:

composer require dsnr/obsidian-commonmark-extension

Usage

To use the extension, create a new League\CommonMark\Environment\Environment instance, register the extension with the addExtension() method, and pass the environment to a new League\CommonMark\CommonMarkConverter instance:

The extension expects the image file names to be kebab cased eg. example-image.ong

use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment\Environment;
use Dsnr\ObsidianCommonmarkExtension\ObsidianConverterExtension;


$environment = new Environment();
  $environment->addExtension(new ObsidianConverterExtension());

$converter = new CommonMarkConverter([], $environment);

echo $converter->convertToHtml('![[Example Image.png]]);

Configuration

obsidian-commonmark-extension includes a configuration schema that defines the obsidian.image_base_url option as a string type with an empty default value. You can modify this option by passing an array of configuration options.

By default, the extension's image base URL is an empty string, so the image URL will be displayed exactly as written. To set a custom image base URL, set the obsidian.image_base_url :

use League\CommonMark\CommonMarkConverter;
use League\CommonMark\Environment\Environment;
use Dsnr\ObsidianCommonmarkExtension\ObsidianConverterExtension;

$config = [
  'obsidian' => [
    'base_image_path' => asset('/images/')
  ]
];

$environment = new Environment($config);
$environment->addExtension(new ObsidianConverterExtension());

$converter = new CommonMarkConverter([], $environment);

echo $converter->convertToHtml('![[Example Image.png]]);
