arglite
A lightweight, explicit argument parsing library for Python programs.
I made this for a teaching machine project I'm working on (I needed a custom argument parser for reasons), and I'm always too impatient to use argparse.
Quick start
import arglite
arglite.parser.require("name", type=str)
arglite.parser.optional("count", default=1, type=int)
arglite.parser.flag("verbose")
def main():
print(arglite.parser.name)
print(arglite.parser.count)
print(arglite.parser.verbose)
if __name__ == "__main__":
main()
python main.py --name Yo --count 5 --verbose
Documentation
Full documentation is available at arglite.readthedocs.io.
Installation
pip install arglite
Notes
- Flags are case-sensitive.
- Both
-f/--flagand--flag=value/-f=valuesyntaxes are supported. - Values containing spaces work when passed via the shell's normal quoting rules.
- Empty string values (
--name "") are preserved. ast.literal_evalis used for type inference when no explicittypeis given.
