Development Setup

This page covers working on Prune itself.

Prerequisites

• PHP 8.4+
• Composer

Clone and install

git clone https://codeberg.org/renfordt/prune.git
cd prune
composer install

Running the tool from source

php bin/prune src

Quality checks

Prune ships with a full suite of quality tooling, wired up as Composer scripts.

Run everything

composer test

This runs, in order: a Rector dry-run, a Pint style check, PHPStan, and PHPUnit.

Individual checks

Command	What it does
composer test:unit	PHPUnit test suite
composer test:types	PHPStan static analysis (level max)
composer test:lint	Pint code-style check (no changes)
composer test:refacto	Rector dry-run (no changes)

Auto-fixing

Command	What it does
composer lint	Fix code style with Pint
composer refacto	Apply Rector refactorings

Running a single test

vendor/bin/phpunit --filter=MethodName

Conventions

• declare(strict_types=1); in every PHP file (enforced by Pint, PSR-12 preset).
• PHPStan runs at level max on src/.
• Tests use the #[CoversClass], #[UsesClass], and #[Test] attributes; strict coverage metadata is enforced.
• Test fixtures live in tests/Fixtures/.
• Namespaces: Renfordt\Prune for src/, Renfordt\Prune\Tests for tests/.
