airbagclimenu 1.1.1

A python package that makes it easy and intuitive to create good looking CLI menus

AirBag CLI Menu

CLI menu module for python3 by AirBag65

Getting started

To use the module you should be working within a virtual environment, or venv for short. If you don't already have one set up you can run one of these commands:

Windows:

python -m venv <name-of-venv>

MacOS / Linux:

python3 -m venv <name-of-venv>

When your venv is ready, you enter it with the following command:

Windows:

<name-of-venv>\Scripts\activate

MacOS / Linux:

source <name-of-venv>/bin/activate

When you have activated the virtual environment and running from within it, you can install airbagclimenu, with one of the following commands:

Windows:

pip3 install airbagclimenu

MacOS / Linux:

pip install airbagclimenu

Usage

Make sure to use this exact import statement for the following to work:

from airbagclimenu import Menu

To create and run the menu, you do as follows:

menu = Menu.CLIMenu()
menu.run()

The construcor for the menu takes an optional argument quit_stmt which is True by default. It provides an option to quit the menu that you don't have to add yourself. When the quit option is present, the menu will run indefinitly, meaning you don't have to restart it for each time after choosing an option. This loop is however not present if the quit statement is not there. If you which not to have the quit statement, you simply pass the argument False into the construcor when creating the object.

The run method also takes an optional argument clear_screen, which determines whether the screen should clear after each option. It's default value is True but can easily be switched of by giving the argument False to the run method.

To add alternatives in the menu you have two options. You can add a function that will execute when that option is chosen, or you can add a submenu, which reveals more options when chosen.

add_menu_option(menu_option: MenuOption)

This method takes one parameter which should be of type MenuOption. See example usecase below:

menu = Menu.CLIMenu()
# You can add a submenu directly by creating it as a parameter like this
menu.add_menu_option(Menu.MenuOption("Submenu 1"))
# Or you can create it as a variable and use the variable as the parameter
option2 = Menu.MenuOption("Submenu 2")
menu.add_menu_opntion(option2)

The second option is recommended in order to be able to add even more submenus and functions to the submenu.

add_func(functionality, title: str)

This method takes two parameters. The first paramter is a function object, and the second is the title that will be displayed in the menu. See usecase below:

menu = Menu.CLIMenu()
def greet():
    print("Hello There!")

menu.add_func(greet, "Say Hello")

As of version 1.1.0 the function used does now support parameters. If the function does not take arguments, it will just run it directly. If it however does take arguments, you will be prompted to enter these when you try to run the function via the menu. It will look like this:

--- Args ---
argument_1: <value of arugment>
argument_2: <value of argument>
------------ 

The name of the argument will be displayed instead of argument_1 etc.

Example Program

from airbagclimenu import Menu
import random

menu = Menu.CLIMenu()

def roll_die():
    val = random.randint(1,6)
    print(f"You rolled a {val}")

def greet1():
    print("Hello There!")

def greet_all():
    print("Hello, World!")

menu_op = Menu.MenuOption("Greetings")
menu_op.add_func(greet1, "Greet person")
menu_op.add_func(greet_all, "Greet everyone")

menu.add_menu_option(menu_op)
menu.add_func(roll_die, "Roll A Die")
menu.run()

The output of this program will be the following:

[1] Greetings
[2] Roll A Die
: 1

The 1st option was chosen here so the program enters this state:

[1] Greet person
[2] Greet everyone
: 1
Hello There!
