TinyMenu

TinyMenu is a simple yet effective utility to simplify and speed up the creation of customizable command-line menus in Python. It is marked by its plain and basic functionality, leaving implementation details up to the developer.

Usage

In order to use TinyMenu functionality the following import statement is required:

import tinymenu

Creating the menu

The code snippet below will create a basic command-line menu containg one command. An explanation and other available attributes and functions are documented below.

def handle_help_command(cmd, *args):
    """
    Function that is called when user enters 'help' command
    """
    print('You entered the help command!')

menu = tinymenu.TinyMenu()
menu.prompt = '$> '

command = tinymenu.Command('help', handle_help_command)
command.arg_limit = [0] # Don't allow any command arguments

menu.add_command(command)
menu.run()

Output:

$> help
You entered the help command!

  • 1st argument: entered command [string]
  • 2nd argument: command arguments [*string]
  • e.g.: def handle_unknown_command(cmd, *cmd_arguments)
• invalid_args_handler (expects method/function) - Stores method/function to be called when a command with invalid command arguments was entered
  • 1st argument: entered command [Command (see below)]
  • 2nd argument command arguments [string]
  • e.g.: def handle_invalid_args(cmd, *cmd_arguments)
• add_command(command) - Adds a command to the menu
  • command - Command (see below) to be added
