Iterate over open issues using the 'gh' command, and offer to close them.

gh-stale-issue-closer.sh

#!/bin/sh
# Get a list of open issues using the 'gh' command from GitHub.
# By default this gives at most 30 answers.
# We print only the number.
# Then we iterate over these issues and check each one, offering to close it.

# There are a few sample queries.
# Make sure one of the ISSUES commands is uncommented.

# 1. Get open issues last updated before 2019.
# Sort the oldest one first.
ISSUES=$(gh issue list --search="updated:<2019-01-01, sort:updated-asc" --json number --jq ".[]|.number")

# 2. Get open issues belonging to a milestone.
# Milestones are not used much in the plone GitHub organisation.
# I guess only here:
# https://github.com/plone/Products.CMFPlone/milestones
# ISSUES=$(gh issue list --milestone "Plone 4.3" --json number --jq ".[]|.number")

# 3. Simply all issues.
# ISSUES=$(gh issue list --json number --jq ".[]|.number")

CLOSING_COMMENT="Closed due to long inactivity. Please reopen if this is still relevant for Plone 5.2 or 6. You could check one of the demo sites: https://plone.org/what-is-plone/plone/try-plone"
