Explanation of each folder/file:

  • grepy/: This is your main package/module. It contains the core logic for your grep functionality. You may have multiple modules inside this package, depending on the complexity of your application.

  • tests/: This folder contains unit tests for your application. Each module in your grepy/ package should have a corresponding test module in the tests/ folder.

  • setup.py: This file is used for packaging and distribution. It defines metadata about your project and its dependencies.

  • requirements.txt: This file lists the dependencies required for your project. Users can install these dependencies using pip install -r requirements.txt1.

  • README.md: Documentation for your project. It should include information about how to install, configure, and use your CLI app.

  • LICENSE:2 Include a license file that specifies the terms under which your software is distributed.

  • grepy_cli.py: This is the script that users will run from the command line to interact with your tool. It should handle command-line arguments and invoke the functionality provided by your grepy/ package.

This structure provides a good separation of concerns and makes it easy to expand your project in the future. You can further break down the grepy/ package if your application becomes more complex.
