README

The Liquid engine we use to render themes on YouCan. If you're building a theme, you probably want the theme docs instead.

Install

composer require youcanshop/liquid

Needs PHP 8.0+.

Usage

use YouCan\Liquid\Template;

$template = new Template();
$template->parse('Hello, {{ customer.name }}!');

echo $template->render(['customer' => ['name' => 'Ada']]);

Custom tags and filters:

$template->registerTag('section', SectionTag::class);
$template->registerFilter('money', fn($amount) => number_format($amount, 2));

Drops

Drops are objects whose fields only load when a template reads them:

use YouCan\Liquid\Drop;

class ProductDrop extends Drop
{
    public function __construct(private Product $product) {}

    public function name(): string
    {
        return $this->product->name;
    }

    public function reviews(): array
    {
        return Review::forProduct($this->product->id);
    }
}

For dynamic keys (e.g. a lookup by handle) override hasKey() and invokeDrop().

Differences from standard Liquid

• first and last work mid-path: collection.products.first.name
• quoted, numeric and variable keys: collections['all'], products[0], all_products[handle]
• map, sort and where read drop fields
• drops are always truthy, and compare by value when they implement JsonSerializable

Development

composer test
vendor/bin/php-cs-fixer fix --dry-run --diff

To release, run ./release.sh -p (or -m, -M), then create the GitHub release for the new tag with gh release create <tag> --generate-notes.
