getargv 0.14

Python bindings to libgetargv, a library to correctly and quickly get other process's args

This module uses libgetargv to obtain binary string representations of the arguments of other processes on macOS.

Motivation

On macOS you must use the KERN_PROCARGS2 sysctl to obtain other proc's args, however the returned representation is badly documented and a naive approach doesn't deal with leading empty args. libgetargv parses the results of the sysctl correctly, and this module provides Python bindings to libgetargv.

Installation

Install the module with pip by executing:

$ pip install getargv

Usage

import os
import getargv
getargv.as_bytes(os.getpid()) #=> b'arg0\x00arg1\x00'
getargv.as_list(os.getpid()) #=> [b'arg0',b'arg1']

Development

After checking out the repo, run python setup.py build. Then run python setup.py install. Then, run python test.py to run the tests. You can also run python -i load.py for an interactive prompt that will allow you to experiment. Python code goes in the file src/getargv/__init__.py, C code goes in the file src/getargv/getargvmodule.c.

To install this module onto your local machine, run python setup.py build && python setup.py install. To release a new version, update the version number in pyproject.toml, and then run make upload-production, which will create a git tag for the version, push git commits and the created tag, and push the .whl file to pypi.org.
