py_command_wrapper

This repository contains a simple wrapper around the Python subprocess module, more specifically, around the run function.

Usage

Should be used as a python module. Can be installed in a Pipfile with

py_command_wrapper = { git = 'https://gitlab.inria.fr/aljanon-experiment-framework/py_command_wrapper.git', editable = true }

It provides five classes:

  • Command: Abstract Base Class, the constructor needs a pathlib.Path for the command working directory.
  • RunArgs: Accepts a list of strings representing the command and its arguments. The whole command line, stdout, stderr and the return code are all logged at the trace level using the loguru logger.
  • RunArgsSaveStdout: Same as RunArgs, except it saves the command's standard output at the given path.
  • Copyfile: Copies the contents of a file from the input path to the output path. Both path are fully resolved, following all potential links. No checks are done regarding the permissions or the existence of the output file. The file's contents are not logged.
  • CommandList: List of commands. Can be added/removed with append/remove.

Dependencies

This module requires loguru for logging. This module does not configure the logger itself, please see py_loguru_wrapper instead.
