Forte

the ... strongest part of the blade

https://www.merriam-webster.com/dictionary/forte

Forte is a Laravel Blade parser and AST manipulation library.

Quick Start

use Forte\Facades\Forte;
use Forte\Rewriting\NodePath;

// Parse a Blade template into a document
$doc = Forte::parse('<div class="mt-4">Hello, {{ $name }}!</div>');

// Query with XPath
$divs = $doc->xpath('//div[@class]')->get();

// Rewrite (returns a new document, original is unchanged)
$newDoc = $doc->rewriteWith(function (NodePath $path) {
    if ($path->isTag('div')) {
        $path->removeClass('mt-4');
        $path->addClass('container');
    }
});

echo $newDoc->render(); // <div class="container">Hello, {{ $name }}!</div>

Core Features

Parsing

Forte's three-phase pipeline (lexer, tree builder, document) handles valid and malformed input alike, recovering gracefully with diagnostics.

$doc = Forte::parse($bladeTemplate);
$doc = Forte::parseFile('resources/views/welcome.blade.php');

Immutable Documents

Every mutation returns a new Document instance. Safe to hold references, chain transformations, and compare before/after states.

Tree Traversal and Querying

Walk the tree, find nodes by predicate, or query with XPath 1.0. Blade constructs map to namespaced elements (forte:if, forte:echo) for XPath queries.

use Forte\Ast\TraversalOptions;

// Lazy, fluent collections with optional name filters
$forms = $doc->queryElements('form');
$conditionals = $doc->queryBlockDirectives(['if', 'unless']);
$components = $doc->queryComponents(['x-alert', 'livewire:*']);

// Fast exact lookups and convenient existence checks
$navigation = $doc->elementById('primary-navigation');
$hasHead = $doc->hasElement('head');

// Attribute semantics live on Attribute; ElementNode provides null-safe proxies
$form = $doc->firstElement('form');
$method = $form?->attribute('method');
$isDynamic = $method?->isDynamic() ?? false;
$staticMethod = $form?->staticAttributeValueLower('method');
$classes = $form?->attributeTokens('class') ?? [];

// Navigate relationships without rebuilding ancestor/descendant loops
$owner = $navigation?->closestElement('header');
$links = $navigation?->descendantElements('a');

// Include attribute/tag-name internals when a deep semantic scan is needed
$allEchoes = $doc->allEchoes(TraversalOptions::deep());

// XPath
$doc->xpath('//forte:if')->get();

The original getElements(), findElementsByName(), magic collection properties, and other released query methods remain available. The query* methods add Laravel-style lazy collections without changing those existing contracts.

Rewriting

The visitor pattern with queued operations prevents excessive intermediate documents. Use NodePath for all mutations, including CSS class helpers, attribute manipulation, and structural changes.

$doc->rewriteWith(function (NodePath $path) {
    if ($path->isTag('center')) {
        $path->renameTag('div');
        $path->addClass('text-center');
    }
});

Components and Directives

First-class support for Blade components (<x-alert>), slots (<x-slot:header>), and all directive types (standalone @csrf, blocks @if...@endif).

$component = $doc->findComponentByName('x-alert');
$directive = $doc->find(fn ($n) => $n->isDirectiveNamed('foreach'));

Node Builders

Construct synthetic nodes for replacements and insertions with a fluent API.

use Forte\Rewriting\Builders\Builder;

Builder::element('div')->class('wrapper')->text('Hello');
Builder::directive('if', '($show)');
Builder::echo('$name');
