New submission from Kien Dang <m...@kien.ai>:
`python-config` outputs a usage instruction message in case either the `--help` option or invalid arguments are provided. However there is a small different in the output I/O between the python and shell script versions of `python-config`. In the python version, the message always prints to `stderr`. https://github.com/python/cpython/blob/bc1c49fa94b2abf70e6937373bf1e6b5378035c5/Misc/python-config.in#L15-L18 def exit_with_usage(code=1): print("Usage: {0} [{1}]".format( sys.argv[0], '|'.join('--'+opt for opt in valid_opts)), file=sys.stderr) sys.exit(code) while in the shell script version it always prints to `stdout`. https://github.com/python/cpython/blob/bc1c49fa94b2abf70e6937373bf1e6b5378035c5/Misc/python-config.sh.in#L5-L9 exit_with_usage () { echo "Usage: $0 --prefix|--exec-prefix|--includes|--libs|--cflags|--ldflags|--extension-suffix|--help|--abiflags|--configdir|--embed" exit $1 } This inconsistency does not affect most users of `python-config`, who runs the script interactively. However it might cause issues when run programmatically. ---------- components: Demos and Tools messages: 401054 nosy: kiendang priority: normal severity: normal status: open title: Small inconsistency in usage message between the python and shell script versions of python-config type: behavior versions: Python 3.10, Python 3.11, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45101> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
