## Cleanup previously compiled files
clean:
	@rm -rf app/vendor
	@echo "Removed application dependencies"
	@rm -f patchtool.phar patchtool patchtool.phar.gz
	@echo "Removed build artifacts"

## Install dependencies via composer
depend:
	docker run --rm --interactive --tty --volume ${PWD}/app:/app composer install --ignore-platform-reqs

## Build phar file
build:
	@if [ ! -d app/vendor ]; then\
		echo "Missing vendor folder, run 'make depend'";\
		exit 1;\
	fi
	php -f build.php
	chmod +x patchtool.phar
