Some handy Python utilities

A sample to learn Python packaging

Install from source

cd <repo root>
pip install .

python setup.py install (deprecated and problematic)

Build distributions ( Replaced with Actions / cibuildwheel for multiple python versions and platforms)

# build for current python version
rm -rf dist/* && python setup.py sdist bdist_wheel

Build and Test - cibuildwheel locally for current platform

pip install cibuildwheel
# build with docker
cibuildwheel --platform linux . 
# cibuildwheel config in pyproject.toml

Publish to pypi ( Replaced with Actions / cibuildwheel for multiple python versions and platforms)

twine upload dist/*

Github Actions

The github action workflow has been configured to run build, test and publish to pypi with cibuildwheel which builds cython extension for multiple python versions and platforms.

The workflow is configured to run manually, not to waste resources on each commit, or automatically when a release is created.

The publish job is executed only when a release is created.

Usage - Functions

import pxutil as px

# run a command and capture stdout, stderr
r = px.bash('ls')
print(r.stdout)

# run a command like bash -x, not capture stdout, stderr
px.bashx('ls')

# shell alike grep
px.grep('ab','abc\ndef')

# normalize a path, by default no symlink resolution
px.normal_path('~/project/src/../README.rst')

px.trim_docstring('''
    ab
        cd
    ef
    '''
    )

# change work directory
with px.set_work_path("~") as p:
    os.listdir()

# import any module in a path
conf = px.import_any('~/config/config1.py')
print(conf.server_ip)

# exit program if return value is an exception
@px.exit_on_exception
def to_int(any):
    if isinstance(dict):
        return Exception('dict is not supported to convert to int.')
    return int(any)

# bespoke request, return decoded content or Exception if any error
# compatible with requests.request parameters
px.request()
NB: This logs requests and responses to files if log level is DEBUG, and log level and directory 
can be configured via environment variable PX_LOG_LEVEL (DEBUG) and PX_LOG_DIR.

# shorthand of px.request('POST',...)
px.post()

# set up loggers
px.setup_logger()

Usage - CLI

px.loop -h      # run a command in loop
px.chat -h      # chat cli based on chatGPT
px.runc -h      # compile and run single c file with gcc
px.ls.mod -h    # list content of a module/package: submodules, classes, functions.

Test
