cli-ih 0.6.0.2

A background command handler for python's command-line interface.

InputHandler Library

A lightweight Python library for creating interactive command-line interfaces with custom command registration and input handling. It supports threaded input processing and includes enhanced logging with color-coded output.

Features

• Command registration system with descriptions
• Threaded or non-threaded input handling
• Colored logging with support for debug mode
• Built-in help, debug, and exit commands
• Error handling for missing or invalid command arguments
• NEW: Register commands with decorators

Installation

pip install cli_ih

Quick Start

from cli_ih import InputHandler

def greet(args):
    print(f"Hello, {' '.join(args)}!")

handler = InputHandler(cursor="> ")
# NEW
@handler.command(name="add", description="Performs the `+` operator on the first 2 arguments.") # The name param will use the func name if its not provided
def add(args):
    print(int(args[0])+int(args[1]))

handler.register_command("greet", greet, "Greets the user. Usage: greet [name]")
handler.start()

# Now type commands like:
# > greet world
# Hello, world!
# > add 1 2
# 3
# > help
# Available commands:
#   help: Displays all the available commands
#   debug: If a logger is present changes the logging level to DEBUG.
#   exit: Exits the Input Handler irreversibly.
#   add: Performs the `+` operator on the first 2 arguments.
#   greet: Greets the user. Usage: greet [name]
#
# > debug
# > exit

Additional Info

• You can provide a valid logger logger=logger to the InputHandler to enable logging (this will be removed soon)
• You can provide the thread_mode param to the InputHandler class to set if it shoud run in a thread or no. (If you are using the cli-ih module on its own without any other background task set thread_mode=False to false)
• You can also provide a cursor param to the InputHandler class to set the cli cursor (default cusor is empty)
