reverse_argparse
Whereas argparse is concerned with taking a bunch of command line
arguments and parsing them, this package is intended to do the opposite; that
is, it'll take the parsed arguments and create the effective command line
invocation of the script that generated them. The motivation is to be able to
tell users exactly what was used for all of the options, taking into
consideration any defaults and other transformations that might've been applied
in the midst of parsing, such that users are able to reproduce a prior run of a
script exactly.
Installation
To get up and running with reverse_argparse, simply:
python3 -m pip install reverse-argparse
Usage
Once the package is installed, you can simply
from argparse import ArgumentParser
from reverse_argparse import ReverseArgumentParser
# Parse the command line arguments.
parser = ArgumentParser()
# Build out the parser however you like.
args = parser.parse_args()
# Optionally post-process any `args`, as needed.
# Do whatever you need to in the script.
# Wrap things up.
print("This script executed the following:")
unparser = ReverseArgumentParser(parser, args)
print(unparser.get_pretty_command_line_invocation())
For more detailed usage and API information, please see our documentation.
