Create argparser automatically from functions
Project description
Overview
A wrapper around argparser to help build CLIs from functions. Uses type-hints extensively :snake:.
Setup
:gear: Installation
Install it directly into an activated virtual environment:
$ pip install arger
or add it to your Poetry project:
$ poetry add arger
:books: Usage
- create a python file called test.py
from arger import Arger
def main(param1: int, param2: str, kw1=None, kw2=False):
"""Example function with types documented in the docstring.
:param param1: The first parameter.
:param param2: The second parameter.
"""
print(locals())
if __name__ == '__main__':
Arger(main).run()
-
Here Arger is just a subclass of
ArgumentParser. It will not conceal you from using otherargparselibraries. -
run this normally with
python test.py 100 param2
- Checkout examples folder and documentation to see more of
argerin action. It supports any level of sub-commands.
Features
- Uses docstring to parse help comment for arguments. Supports
- Flags will be generated from parameter-name.
If needed you could declare it inside docstring like
:param arg1: -a --arg this is the document. Also one can usedef main(arg1:int=Argument(flags=('-a', '--arg'), ...): ... - The decorated functions can be composed to form nested sub-commands of any level.
- No external lib dependency
- Most of the Standard types supported. Please see examples for more supported types with examples.
- All argument to
ArgumentParser.add_argumentis supported. It can be updated witharger.Argumentclasses. *argssupported but no**kwargssupport yet.- all optional arguments that start with underscore is not passed to
Parser. They are considered private to the function implementation. Some parameter names with special meaning_namespace_-> to get the output from theArgumentParser.parse_args()_arger_-> to get the parser instance
This project was generated with cookiecutter using jacebrowning/template-python.
