10print

Nodejs implementation of the famous one-line Commodore 64 BASIC program:

10 PRINT CHR$(205.5+RND(1)); : GOTO 10. 

This project was inspired by 10 PRINT book (http://10print.org/) where you can find all the information about the original program. This script will print on the console an infinite random sequence composed only by chars / and \ in a fancy pattern.

Getting Started

To run this script you only need to install and import the npm package, then running the goto10 function. Of course don't forget to kill the process to interrupt the infinite loop :)

Installing

npm install 10print

Usage

For a basic usage run goto10() to print the standard pattern:

let p = require("10print");
p.goto10();

If you want to create your own custom pattern it's possible to call printPattern(config) in this way:

p.printPattern({
    symbol1: "/", // The first symbol of your pattern
    symbol2: "\\", // The second symbol of your pattern
    weight: 0.5 // Value between 0 and 1 that tunes the probability of each symbol to be displayed
})

This is the configuration of the standard pattern. Changing weight value would create a new one with different symbol frequency: setting 0 means to have 100% chance to get first symbol, 1 means 100% chance to get second. With 0.5 there is 50% chance for each symbol. You can change this value and the symbols as well to create your custom pattern.
