README

The argtoml package wraps around argparse. It adds the content of a toml file to the cli options. After parsing, it creates a types.SimpleNameSpace object.

usage

Use argtoml the same as you would use argparse. If you don't provide the location for the toml file, it will search for one in the current directory or any parent directory of the main file (in)directly importing argtoml.

from argtoml import ArgumentParser, arg_parse

parser = ArgumentParser()
parser.add_argument("--path", default="./")
parser.add_argument("--project.name", default="argtoml")
args = arg_parse(parser)

If we, for example have the following config.toml in the same directory as the above script

[project]
author = "Jono"
name = "argconfig"

then args is an object with the following entries.

assert args.path == "./"
assert args.project.author == "Jono"
assert args.project.name == "argtoml"

notes

This is a personal tool thus far, some idiosyncrasies remain:

• Adding dotted arguments not present in the toml might break everything I didn't even test this.
• I didn't test any arrays, they should work?
• I don't feel like adding other formats but toml.
• I don't know if, in the above example, the user can do something like main.py --project {author=jo3} --project.author jjj, but it should crash if they do this.

todos

• Add toml comments as argument descriptions.
• Pretty-print the output of parse_args.
