Datastar language support for tempest/highlight — highlights data-* attributes, $signals, @actions, and expressions.

README 文档

README

Datastar syntax highlighting for tempest/highlight — highlights data-* attributes, $signals, @actions, and expressions in HTML code blocks.

Installation

composer require mbolli/tempest-highlight-datastar

Usage

Register by name

Register the language once on your Highlighter instance, then use it by name:

use Mbolli\TempestHighlightDatastar\Html\DatastarHtmlLanguage;
use Tempest\Highlight\Highlighter;

$highlighter = new Highlighter();
$highlighter->addLanguage(new DatastarHtmlLanguage());

// Use by name or alias
$html = $highlighter->parse($code, 'datastar-html');
$html = $highlighter->parse($code, 'datastar');

Registering the language also overrides the built-in html language (via alias), so <<<HTML heredocs in PHP code and Markdown fenced code blocks tagged ```html automatically get Datastar highlighting.

Pass as object

Alternatively, pass the language directly without registering:

$html = $highlighter->parse($code, new DatastarHtmlLanguage());

What gets highlighted

Datastar data-* attributes — data-signals, data-on, data-bind, data-show, etc.
Signals — $signalName, $$componentSignal
Actions — @get(), @post(), @put(), @patch(), @delete(), etc.
Special variables — el, evt, patch
Expressions inside attribute values are parsed as JavaScript with Datastar extensions

Available Languages

Class	Name	Alias	Extends
`DatastarHtmlLanguage`	`datastar-html`	`datastar`, `html`	`HtmlLanguage`
`DatastarTwigLanguage`	`datastar-twig`	`twig`	`DatastarHtmlLanguage`

Twig

use Mbolli\TempestHighlightDatastar\Twig\DatastarTwigLanguage;

$highlighter->addLanguage(new DatastarTwigLanguage());
$html = $highlighter->parse($code, 'datastar-twig');

This also overrides the built-in twig language, so any code already highlighted as 'twig' will gain Datastar support.

PHP templates

Since DatastarHtmlLanguage overrides the built-in html language, just highlight your PHP files as 'php'. The PhpHeredocInjection resolves <<<HTML blocks via the 'html' name, which now points to DatastarHtmlLanguage — so heredocs and inline HTML automatically get Datastar highlighting.

Markdown

Markdown in tempest/highlight does not parse inline HTML, so no Datastar-specific Markdown language is needed. Since DatastarHtmlLanguage overrides html, fenced code blocks tagged ```html, ```datastar, or ```datastar-html all get Datastar highlighting automatically.

Creating your own language variant

tempest/highlight has no way to globally override HtmlLanguage, so languages like Blade that extend it won't automatically gain Datastar support. You can create your own variant by extending DatastarHtmlLanguage and re-adding the framework-specific injections/patterns.

For example, to create a Blade variant:

use Mbolli\TempestHighlightDatastar\Html\DatastarHtmlLanguage;
use Tempest\Highlight\Languages\Blade\Injections\BladeEchoInjection;
use Tempest\Highlight\Languages\Blade\Injections\BladeKeywordInjection;
use Tempest\Highlight\Languages\Blade\Injections\BladePhpInjection;
use Tempest\Highlight\Languages\Blade\Injections\BladeRawEchoInjection;
use Tempest\Highlight\Languages\Blade\Patterns\BladeComponentCloseTagPattern;
use Tempest\Highlight\Languages\Blade\Patterns\BladeComponentOpenTagPattern;

final class DatastarBladeLanguage extends DatastarHtmlLanguage {
    #[\Override]
    public function getName(): string {
        return 'datastar-blade';
    }

    /** @return list<string> */
    #[\Override]
    public function getAliases(): array {
        return [];
    }

    #[\Override]
    public function getInjections(): array {
        return [
            ...parent::getInjections(),
            new BladeKeywordInjection(),
            new BladePhpInjection(),
            new BladeEchoInjection(),
            new BladeRawEchoInjection(),
        ];
    }

    #[\Override]
    public function getPatterns(): array {
        return [
            ...parent::getPatterns(),
            new BladeComponentOpenTagPattern(),
            new BladeComponentCloseTagPattern(),
        ];
    }
}

The pattern is always the same: extend DatastarHtmlLanguage, override getName(), and re-add the injections/patterns from the original language.
