-# 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
-current_version=$(cat manifest.json | jq -j '.version|split("~")[0]')
-repo=$(cat manifest.json | jq -j '.upstream.code|split("https://github.com/")[1]')
-# Some jq magic is needed, because the latest upstream release is not always the latest version (e.g. security patches for older versions)
-version=$(curl --silent "https://api.github.com/repos/$repo/releases" | jq -r '.[] | select( .prerelease != true ) | select( .tag_name | contains("+") or contains("rc") or contains("beta") or contains("alpha") | not ) | .tag_name' | sort -V | tail -1)

-
-# Later down the script, we assume the version has only digits and dots
-# Sometimes the release name starts with a "v", so let's filter it out.
-# You may need more tweaks here if the upstream repository has different naming conventions.
