# gstack-artifacts-url — canonical-URL helper for the artifacts repo.
|
|
#
|
|
# We store the HTTPS URL as canonical (in ~/.gstack-artifacts-remote.txt) and
|
|
# derive other forms on demand. Centralizes the regex so callers don't each
|
|
# string-mangle, which is how URL-format bugs creep into branch logic
|
|
# (codex Finding #10).
|
|
#
|
|
# Usage:
|
|
# gstack-artifacts-url --to ssh <https-url> # https → git@host:owner/repo.git
|
|
# gstack-artifacts-url --to https <any-url> # idempotent canonicalization
|
|
# gstack-artifacts-url --host <any-url> # extract hostname
|
|
# gstack-artifacts-url --owner-repo <any-url> # extract owner/repo
|
|
#
|
|
# Inputs accepted:
|
|
# https://github.com/garrytan/gstack-artifacts-garrytan

# https://github.com/garrytan/gstack-artifacts-garrytan.git

|

|
|
# Output: the requested form on stdout. Exits non-zero on parse failure with
|
|
# an error on stderr.
