Description

Go version and module path when go.mod exists

#!/usr/bin/env bash
# Go module check
# Read-only: go env GOPATH/version, and go list -m when go.mod exists. No downloads.
# Exit 0 if the toolchain is usable, 1 if GOPATH/module info is incomplete, 2 if go is missing.
# Hosted on Runny.sh. Review the script page before you run it.
