Installation

To get started with userpath, the installation is straightforward. Just open your terminal and run:

pip install userpath

Using the Command-Line Interface (CLI)

After installing, you can access the CLI by typing userpath in your terminal. Here’s a quick reference on its usage:

$ userpath -h
Usage: userpath [OPTIONS] COMMAND [ARGS]...

Options:
  --version   Show the version and exit.
  -h, --help  Show this message and exit.

Commands:
  append     Appends to the user PATH
  prepend    Prepends to the user PATH
  verify     Checks if locations are in the user PATH

This interface allows you to append, prepend, or verify paths in your user environment. For instance, think of the PATH as a road network. If you want to add a new road (or path), you can either place it at the beginning (prepend) or at the end (append) of the existing map. The verification command ensures that the roads you’re considering exist in the current network.

Using the API

If you prefer working with Python, you can utilize the userpath API. Here is how you can implement it:

import userpath

location = r"C:\Users\Ofek\Desktop\test"
userpath.in_current_path(location)  # False
userpath.in_new_path(location)      # False
userpath.append(location)            # True
userpath.in_new_path(location)      # True
userpath.need_shell_restart(location)  # True

In this example, we first check if a specific directory exists in our current and new PATH. By appending it, we’re effectively adding that directory to our PATH, similar to creating a new route in our road network and ensuring ease of access for our applications.

License

The userpath tool is distributed under the terms of the MIT License, allowing you the freedom to use, modify, and share it.

Troubleshooting

If you encounter any issues while using userpath, here are some troubleshooting tips that might help:

• Ensure you have permissions to modify your system PATH.
• If using the API, make sure you are running a compatible Python version.
• Check that the paths you are trying to append or prepend are valid and accessible.
• Consider restarting your shell or terminal after making changes for them to take effect.
