A simple python tool to parse any arg / kwarg arguments in a manner that is easy to parse for the linux shell.

I don't understand

For example:

uvx ShellArgParser@latest a_file --test=something -a -b -no-c another_file

Will print this text:

ARGS_1="a_file"
ARGS_2="another_file"
ARGS_TEST="something"
ARGS_A=1
ARGS_B=1
ARGS_C=0

So running this:

eval $(uvx ShellArgParser@latest --test=something -a -b -no-c)

Will parse the args and kwargs as shell environment variables, handy for use in the shell:

echo $ARGS_TEST  # outputs 'something'

But why would you make this?

Handling user arguments are a major annoyance for me in shell, and in python using fire makes it a breeze, so it's is a great way to avoid reinventing the wheel. Hence, when writing a small shell script, using a python cli tool oneliner makes is a real time saver for me.

Notes:

• -something is parsed as ARGS_SOMETHING=1
• -no-something is parsed as ARGS_SOMETHING=0
• -no_something is parsed as ARGS_SOMETHING=0
• Any None python value is parsed as 0
• A prototype 'pure shell' version of this script can be found in ./ShellArgParser.sh

Getting started

• From pypi:
  • As a uv tool: uvx ShellArgParser@latest --help
  • Via uv: uv pip install ShellArgParser
  • Via pip: pip install ShellArgParser
• From github:
  • Clone this repo then pip install .
