-#=================================================

-# 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=$(curl --location --silent "https://api.github.com/repos/$repo/releases" | jq -r '.[] | select( .prerelease != true ) | .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. 
-if [[ ${version:0:1} == "v" || ${version:0:1} == "V" ]]; then

-#=================================================
-# UPDATE SOURCE FILES
-#=================================================
-
-# Here we use the $assets variable to get the resources published in the upstream release.
-# Here is an example for Grav, it has to be adapted in accordance with how the upstream releases look like.
-
-# Let's loop over the array of assets URLs
-for asset_url in ${assets[@]}; do
