ASCII Ball

Overview

An ASCII text "bounce" animation rendered in the terminal. Implemented in Haskell.

src/Animation.hs

This default version reads data from an INI (initialisation) file to set a default position and velocity for the ball.

Edit the INI file to set the program's starting values in data/start.ini.

src/AnimationV1.hs

This version is the simplest implementation. The configuration is hard-coded in the source file, and the animation frames are individually rendered one after the other in the terminal.

src/AnimationV2.hs

This version reads command-line arguments to set the configuration.

# Syntax:
stack run posX posY velX velY

# Example:
stack run 3 4 1 1

# With GHCI:
ghci> :set args 3 4 1 1
ghci> run

Running Another Version

Import the module's run function into app/Main.hs and call it in main. For example:

module Main where 

import AnimationV2 ( run )

main :: IO ()
main = run

Building and Running

Build and run the application using Stack. See the requested GHC resolve in stack.yaml.
