$attributes onlyStartsWith and exceptStartsWith

[tanthammar]

Regarding Blade components Attribute Bag.

When developing headless Blade Components I miss two methods on the ComponentAttributeBag

{{ $attributes->onlyStartsWith([...]) }}
{{ $attributes->exceptStartsWith([...]) }}

Example use case

<div {{ $attributes->onlyStartsWith(['wire:model', 'x-model']) }} >
    <input 
        {{ $attributes->exceptStartsWith(['wire:model', 'x-model', 'x-data'])->merge(...) }} 
        @change="$dispatch(...)"
    />
</div>

Current solution is a bit to verbose

<div {{ $attributes->whereStartsWith('wire:model') }} {{ $attributes->whereStartsWith('x-model') }} > 
    <input 
        {{ $attributes->except('x-data')->whereDoesntStartWith('wire:model')->whereDoesntStartWith('x-model')->merge(...) }} 
        @change="$dispatch(...)"
    />
</div>

Maybe filter() would work well for these use-cases.

@tanthammar Despite the whereStartsWith and whereDoesntStartWith DocBlocks saying it only accepts a string, you can actually pass an array to these methods as it's being passed to Str::startsWith($haystack, $needles) which accepts an array too.
