Ability to traverse nodes

[khalyomede]

Hi, I would like to know if there is a way to add a custom traverser?

My need is the following: I am building a translation parser (https://github.com/khalyomede/laravel-translate) and I have complex scenarios when x-components are nested with each others

I need to pull translations from different places:

1. Blade Dynamic attributes (like <x-form :title="__('Enter your informations')"></x-form>
2. Echo directives ({{ __('Enter your informations') }} and {!! __('Enter your informations') !!})
3. Components literal values (<x-select><option>@lang("Hi")</option></x-select>)

For the 2. and 3., it is easy using Document::findDirectivesByName("lang") and Document::AllOfType(Echo::class), but for the first one since dynamic attributes could be in any level of nesting, and there is no way to find all dynamic attributes, I would need to make my own traverser and get those

Is there an easy way to do it?

Ok I think I got something working (need some more minutes to make it pass all tests)

$langs = $document->findDirectivesByName("lang");
$choices = $document->findDirectiveByName("choice");
$components = $document->allOfType(ComponentNode::class);
$echos = $document->allOfType(EchoNode::class);

I loop through components, get ComponentNode::getParameters() and it should be fine!

To find all dynamic attributes, we can just go through each of the components in the template, and return all parameters that have the type DynamicVariable:

<?php

use Stillat\BladeParser\Document\Document;
use Stillat\BladeParser\Nodes\Components\ComponentNode;
use Stillat\BladeParser\Nodes\Components\ParameterNode;
use Stillat\BladeParser\Nodes\Components\ParameterType;

    $template = <<<'BLADE'
<x-form :title="__('Enter your informations')">
<x-form :title="__('Enter your informations2')">
    <x-form :title="__('Enter your informations3')">

    </x-form>
</x-form>
</x-form>
BLADE;

$doc = Document::fromText($template);

$dynamicAttributes = $doc->getComponents()->map(function (ComponentNode $node) {
    return $node->getParameters()->where(function (ParameterNode $param) {
        return $param->type == ParameterType::DynamicVariable;
    });
})->collapse();

$dynamicText = $dynamicAttributes->map(function (ParameterNode $param) {
    return $param->value;
})->all();

Yep I did something along the lines, thanks! I think I will not need a "custom traverser" in this case thank you :pray:
