Add blade directive @guest

[LKaemmerling]

As addition to #20087 it would be nice if there is the opposite of @auth, so i implemented it.

[it-can]

If do not pass a guard, will this work?

[m1guelpf]

@it-can Yes

[LKaemmerling]

@it-can yeah it will, it is the same code as #20087. @m1guelpf what do you thing if the @guest can be an "else" for your @auth ?

Like:

@auth

//Is authentificated

@guest 


// Is guest 

@endauth

[m1guelpf]

@LKDevelopment That'd be confusing. I'd suggest keeping both PR's as-is, as making the @guest directive work as an else would be confusing if you only want to use guest...

[it-can]

@LKDevelopment If I add a custom directive to my laravel 5.4 app, I get a error when calling

AppServiceProvider.php

Blade::directive('auth', function ($guard = null) {
    return "<?php if(auth()->guard{$guard}->check()): ?>";
});
        
Blade::directive('endauth', function () {
    return "<?php endif; ?>";
});

This gives an error

@auth
    logged in
@endauth

Undefined property: Illuminate\Auth\AuthManager::$guard

compiles to:

<?php if(auth()->guard->check()): ?>
logged in
<?php endif; ?>

this works...

@auth('web')
    logged in
@endauth

[m1guelpf]

@it-can You have a typo in the directive.
Try this:

Blade::directive('auth', function ($guard = null) {
    return "<?php if(auth()->guard({$guard})->check()): ?>";
});
        
Blade::directive('endauth', function () {
    return "<?php endif; ?>";
});

[it-can]

@m1guelpf yes that works... but when I check this PR, the code is missing the parenthesis?

[it-can]

should this also be changed in #20087 ?

[it-can]

Seems taylor changed it...

No guys!
This is not the guard which is passed, but the complete $expression, with the ().
Nothing to change here!

[m1guelpf]

@mathieutu is rigth. There's nothing to change here.

[m1guelpf]

Remove the extra whitespace here, and your PR is perfect!

@m1guelpf @LKDevelopment Any ideas to work in @LKDevelopment's proposal?

@auth
    // Is authenticated
@guest 
    // Is guest 
@endauth

[m1guelpf]

@Gabriel-Caruso I don't think so. Now it'd be a breaking change...
