Bulk transfer all github issues from one repo to another, keeping labels intact

bulk-transfer-github-issues.sh

#!/usr/bin/env bash
# Migrates all open issues from one repo to another, labeling them with the same labels, and adding a new label
#
# Assumes:
# - the target repo's labels are a superset of the source repo's
# - you have jq installed
# - you have gh installed
#
# Steps:
# 1. Change source_repo to your source repo,
# 2. Change target_repo in migrate-and-label.sh to your target repo, and
# 3. Change "talon" below to the label you want to add to all migrated issues

source_repo=pokey/cursorless-talon
gh issue list --repo $source_repo --json url,labels \
  | jq -r '.[]|{labels: ([.labels[].name, "talon"]|join(",")), url} | tojson | @sh' \
  | xargs -n1 ./migrate-and-label.sh

migrate-and-label.sh

#!/usr/bin/env bash
# Helper script used by `bulk-transfer-github-issues.sh` to migrate and label a single issue
# Expects single arg containing json object with url and comma-separated labels
