# PACKAGE UPDATING HELPER
#=================================================
# This script is meant to be run by GitHub actions: check out .github/workflows/updater.yml
# Since each app is different, maintainers can adapt its contents so as to perform
# automatic actions when a new upstream release is detected.
# GitHub Actions should have made available the following environment variables:
# $ASSETS:
# The ASSETS environment variable is a space-separated list of urls
# of assets published with the latest upstream release.
# $VERSION:
# The new version of the app
# Let's convert $ASSETS into an array.
eval "ASSETS=($ASSETS)"
echo "${#ASSETS[@]} available asset(s)"
#=================================================
# 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
echo "Handling asset at $asset_url"
# Assign the asset to a source file in conf/ directory
# Here we base the source file name upon a unique keyword in the assets url (admin vs. update)
# Leave $src empty to ignore the asset
case $asset_url in
*"admin"*)
src="app"
;;
*"update"*)
src="app-upgrade"
;;
*)
src=""
;;
esac
# If $src is not empty, let's process the asset
if [ ! -z "$src" ]; then
# Create the temporary directory
tempdir="$(mktemp -d)"
# Download sources and calculate checksum
filename=${asset_url##*/}
curl --silent -4 -L $asset_url -o "$tempdir/$filename"
checksum=$(sha256sum "$tempdir/$filename" | head -c 64)
# Delete temporary directory
rm -rf $tempdir
# Get extension
if [[ $filename == *.tar.gz ]]; then
extension=tar.gz

#=================================================
# 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.
# Note that there should be no need to tune manifest.json or the READMEs, since
# the GitHub Action workflow and yunohost-bot take care of them, respectively.
