I do not maintain do-runtime anymore.

do-runtime

This is an open source for the minimalist machine language Do.

Do is a fictive machine language that reads, writes and jumps on a tape, working like a Turing machine. Read more about Do.

Example

Let's assume you have the following Do code.

0 0		0 0 0 0 0 0 0 0   // read from 0
0 1		0 0 0 0 1 0 1 1   // write to 11
1 0		1 1 1 1 1 1 1 1   // jump to the end

To execute it, load the runtime and initialize a new instance.

var DoRuntime = require('do-runtime');
 
var r = Object.create(DoRuntime);

You have to pass the tape as an array of numbers. The second parameters is an optional options object.

r.init([
    0, 0,	0, 0, 0, 0, 0, 0, 0, 0,
    0, 1,	0, 0, 0, 0, 1, 0, 1, 1,
    1, 0,	1, 1, 1, 1, 1, 1, 1, 1
], {   // The following are the default values.
    commandLength: 2,
    addressLength: 8,
    commands: ['read', 'write', 'goto', 'gotoIf'],
    pointer: 0,
    storage: 0
});

When you call run, the Do runtime will execute the program until it jumps to the end of the tape (or beyond).

Install

npm install do-runtime
