Setting up PHPCS in GitLab only on changed files

I wanted to save some time on our runners in GitLab and decided to only run phpcs on changed files for that merge request. I also wanted it to run as a git commit hook to try and prevent bad code from even getting pushed up.

What I came up with was to add two shell scripts to the repo under the folder bin.

changed.sh (chmod u+x)

git fetch origin master git diff --name-status origin/master | grep '\.php$' | grep -v "^[RD]" | awk '{ print $2 }'

Add the following to your .gitlab-ci.yml

codestyle: stage: testing needs: ["composer"] image: lorisleiva/laravel-docker script: - files=`sh bin/changed.sh` - phpcs --config-set ignore_warnings_on_exit 1 - if [ ! -z ]; then echo $files | xargs phpcs; fi

changed.sh could just go inside the yml file, but I like using it before deploys.
