REPLI - Python

REPLI is a Python library for creating interactive command line interfaces (CLIs). It is designed to simplify the process of creating CLIs by abstracting away many of the complexities associated with command-line interaction.

Features

• Automatic handling of command-line arguments
• Auto-generated help system
• Built-in support for tab completion
• Interactive prompt generation
• Support for customizing prompt formatting

Installation

To install REPLI, simply use pip:

pip install repli-py

Usage

Using REPLI is easy. First, import the repli module and create an instance of the REPLI class:

import repli

my_repli = repli.REPLI()

Next, add commands to your REPLI instance by decorating functions with the @my_repli.command() decorator:

@my_repli.command()
def hello(name):
    """Say hello to someone"""
    print(f"Hello, {name}!")

You can then start your REPLI instance:

my_repli.start()

And when you run it, you should see something like this:

>>> hello world
Hello, world!

Customizing the prompt

REPLI comes with a default prompt that looks something like this:

>>>

But you can customize the prompt by passing a prompt argument to the REPLI constructor:

my_repli = repli.REPLI(prompt="> ")

Conclusion

REPLI is a powerful tool for creating command-line interfaces in Python. With its automatic argument parsing, help system, and tab completion, it takes care of many of the tedious aspects of CLI development, leaving you free to focus on your application logic.
