# This is complementary script to our lint-staged setup. This is a bit of magic, but please bare with me.

# This script finds new files during the CI job (compared to the master), and
# 1. prints all the files in all commits which are not in the master
# 2. sorts them and unique them
# 3. we care just for src/*.tsx?
# 4. ignore return code of grep :)

# During the PR you might have created files and then deleted them in another commit,
# those files will be considered as touched so we need to filter them out
