Language

language is a very small library for building DSLs in Javascript.

npm install language

Why?

Because magic scope! and because no globals!

var language = require('language');

var robot = language({
position: {x: 0, y: 0},

moveLeft: function() {
this.position.x--;
},

moveRight: function() {
this.position.x++;
},

moveUp: function() {
this.position.y--;
},

moveDown: function() {
this.position.y++;
},
});

robot(function () {
console.log(position);

moveDown();
console.log(position);

moveRight();
console.log(position);
});

How?

Read the source, it's small.
