Fluent Validation Rector

Appearance

Why this package? ​

Rector rules that migrate Laravel validation to sandermuller/laravel-fluent-validation. Pipe-delimited strings, array-based rules, Rule:: objects and Livewire #[Rule] attributes all become FluentRule chains.

php
// Before
return [
    'email'  => 'required|email|max:255',
    'tags'   => ['nullable', 'array'],
    'tags.*' => 'string|max:50',
];

// After
return [
    'email' => FluentRule::email()->required()->max(255),
    'tags'  => FluentRule::array()->nullable()->each(
        FluentRule::string()->max(50),
    ),
];

Tested on a production codebase: 448 files converted, 3,469 tests still passing.

What it will not do ​

The rectors bail rather than guess. A shape they cannot prove equivalent is left exactly as it was and written to the skip log, so a migration is never silently lossy. Detection and limitations lists what stays untouched and why.

What it costs you ​

One rector.php, a formatter pass after it, and a diff review. Two of the sets, SIMPLIFY and POLISH, are deliberately not in ALL: they run after you have verified the first conversion.
