# 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.

|

#=================================================
|

|

# 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
