# PACKAGE UPDATING HELPER
#=================================================
# This script is meant to be run by GitHub Actions
# The YunoHost-Apps organisation offers a template Action to run this script periodically
# Since each app is different, maintainers can adapt its contents so as to perform
# automatic actions when a new upstream release is detected.
#=================================================
# FETCHING LATEST RELEASE AND ITS ASSETS
#=================================================
# Fetching information

# Some jq magic is needed, because the latest upstream release is not always the latest version (e.g. security patches for older versions)
file=$(curl --silent "https://fossil.kd2.org/paheko/juvlist" | jq -r '.[] | select( .name | contains("paheko") and contains(".tar.gz") ) | select( .name | contains(".deb") or contains(".asc") or contains("beta") or contains("alpha") | not ) | .name' | sort -V | tail -1)

# SPECIFIC UPDATE STEPS
#=================================================
# Any action on the app's source code can be done.
# The GitHub Action workflow takes care of committing all changes after this script ends.
#=================================================
# GENERIC FINALIZATION
#=================================================
# Replace new version in manifest
