Add directive @bool to Blade

[david-valdivia]

Add @Bool directive functionality to Blade, allowing boolean values to be printed directly into strings or used in object construction.

Examples:

JS

<script>
    let config = {
        isActive: @bool($isActive),
        hasAccess: @bool($hasAccess)
    };
</script>

Alpine

<div x-data="{ isActive: @bool($isActive) }">
    <button :class="{ 'active': isActive }">Toggle</button>
</div>

Bootstrap:

<div class="dropdown">
  <button class="btn btn-secondary dropdown-toggle" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="@bool($hasPopup)" aria-expanded="@bool($isExpanded)">
    Dropdown button
  </button>
  <div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
    <a class="dropdown-item" href="#">Action</a>
    <a class="dropdown-item" href="#">Another action</a>
    <a class="dropdown-item" href="#">Something else here</a>
  </div>
</div>

Your code doesn't print anything for the "false" path.

return  "<?php echo {$condition} ? 'true' : 'false'; ?>";

This is probably one of the few cases where an eval() test would have found the error above, like so:

public function testCompileBool(): void
    {
        $someViewVarTruthy = 123;
        $compiled = $this->compiler->compileString('@bool($someViewVarTruthy)');

        ob_start();
        eval(substr($compiled, 6, -3));
        $this->assertEquals('true', ob_get_clean());

        $someViewVarFalsey = '0';
        $compiled = $this->compiler->compileString('@bool($someViewVarFalsey)');

        ob_start();
        eval(substr($compiled, 6, -3));
        $this->assertEquals('false', ob_get_clean());

    }

You're right, it didn't consider a Falsey values, i added a Falsey support and a couple of test for NULL and Class instances.

btw it works with @js(true) out of the box.

@david-valdivia What's the difference between @js($condition) and @bool($condition)? Would you care to contribute to the docs?

no problem, @Bool is thinked only in print a boolean values, means that it could recognize between Falsey and Truthy values o diference with @js that convert into json.

Cases:

Results:

@Bool() always returns a boolean value, @js() converts into a json.
