PHP CS Fixer — Patch Summary

Violations Fixed

1. nullable_type_declaration — ?Type → Type|null

Configured in php-cs-fixer.php:

'nullable_type_declaration' => ['syntax' => 'union'],

This means every ?Foo must be written as Foo|null.

Files changed and their specific fixes:

File	Old	New
src/ConsoleIO.php	?float $startTime	float|null $startTime
src/ConsoleIO.php	int|null $attempts (already ok)	verified
src/ConsoleIO.php	int|null $size (already ok)	verified
src/ConsoleIO.php	string|null askAndHideAnswer return	string|null (union — ok)
src/NullIO.php	int|null $attempts	int|null (union — ok)
src/NullIO.php	int|null $size	int|null (union — ok)
src/BufferIO.php	?OutputFormatterInterface $formatter	OutputFormatterInterface|null $formatter
src/CLIApplication.php	?IOInterface $io property	IOInterface|null $io
src/CLIApplication.php	?array $argv param	array|null $argv
src/Depends/RenderContext.php	(no nullable types)	verified clean
src/Depends/Spinner.php	?array $frames	array|null $frames
src/Components/Component.php	?Hooks $hooks	Hooks|null $hooks

2. single_line_empty_body — collapse empty {} blocks to one line

Empty method bodies that span multiple lines must be on one line:

// Before (violation):
public function afterRender(State $state, RenderContext $context): void
{
}

// After (correct):
public function afterRender(State $state, RenderContext $context): void {}

Files changed:

File	Methods collapsed
src/AbstractPrompt.php	beforeRenderHook(), afterRenderHook()
src/Depends/Renderer.php	afterRender()
src/NullIO.php	write(), writeError(), writeRaw(), writeErrorRaw(), overwrite(), overwriteError()

3. braces_position — opening brace placement

The @PER-CS ruleset enforces consistent brace positions. This primarily affects the same empty-body methods as above (the { was on a new line, now it's inline with }).
