fooargs

fooargs is a command-line argument parsing library for the Python programming language. It aims to provide a simple and intuitive way to define and parse arguments passed to Python scripts. The library allows developers to specify expected arguments, their types, default values, and help messages.

The core functionality of fooargs revolves around creating an argument parser object and then defining the arguments that the script will accept. This is typically done by calling methods on the parser object, such as `add_argument()`. Each call to `add_argument()` specifies a particular argument, its name, and various optional attributes.

Once the arguments are defined, the `parse_args()` method is called on the parser object. This method inspects the command-line arguments provided to the script and attempts to match them with the defined arguments. If successful, it returns an object containing the parsed argument values, which can then be accessed by name.

fooargs supports various argument types, including strings, integers, floats, and booleans. It also handles optional arguments, positional arguments, and arguments with default values. Help messages are automatically generated and displayed to the user when the script is run with a `--help` flag, making it easier for users to understand how to use the script. The library's simplicity makes it a suitable choice for smaller projects or for developers who prefer a straightforward approach to argument parsing.
