Library

A Composer package that ships classes and no executable - a Behat context, a PHPUnit extension, a framework plugin, a PSR implementation - needs the PHP tooling without an entry point.

Decline both PHP entry points to get it:

./init.sh --namespace=AcmeApp --name=acme-app --author="Jane Doe" \
  --php --no-php-command --no-php-script

Interactively, answer "n" to both Use CLI command app and Use simple script.

What you get

• composer.json with the PSR-4 autoloader and no bin section
• src/Example.php and tests/phpunit/Unit/ExampleUnitTest.php - a single placeholder class and its test
• PHP_CodeSniffer, PHPStan and Rector configuration scanning src and tests/phpunit
• PHPUnit configuration with coverage over src
• The Test PHP and Release PHP workflows, the latter creating a release for each tag without attaching an artifact

Neither php-command nor php-script is generated, and neither is box.json or the PHAR build, so a class-only package has nothing to unpick afterwards.

Getting started

Replace Example with the library's own classes under src/ - they are autoloaded as AcmeApp\App\ - and cover each one with a test in tests/phpunit/Unit/.

Keep at least one class: PHP_CodeSniffer and PHPStan both report an error when they are pointed at a project that holds no PHP file at all.
