RJS Assistant

PhpStorm-style PHP refactorings for VS Code and Cursor.

Features

Press Alt+Enter (or Ctrl+.) on a PHP closure or arrow function to see available refactorings:

Convert closure to arrow function

// Before
$fn = function (int $x) use ($y) { return $x + $y; };

// After
$fn = fn (int $x) => $x + $y;

The refactoring is offered when the closure:

• Has exactly one return statement
• Does not use by-reference captures (use (&$var))
• Does not have a void return type

Convert arrow function to closure

// Before
$fn = fn (int $x) => $x + $y;

// After
$fn = function (int $x) use ($y) { return $x + $y; };

Automatically detects which outer-scope variables need to be listed in the use() clause.

Supported features

• Typed parameters and return types are preserved
• Static closures/arrow functions
• $this is excluded from the use() clause (auto-bound in non-static closures)
• Nested closures (refactoring applies to the innermost one at cursor)
