Install

npm install allegory

Note: The code uses generators (--harmony flag)

How it works

Write JavaScript in a file, say code.js

function sayHii() {
	alert("h!");
}

sayHii();

And then draw something with * on another file, say template

         ***           **     **
        *****          **
         ***           *****  **
          *            ** **  **
     ************      ** **  **
          *            ** **  **
          *
          *
         * *
        *   *
       *     *
      *       *

then you can

allegory code.js template

and you get

eval(atob("\
         ZnV           uY     3R \
        pb24g          c2        \

         g p                     \
        O   w                    \
       o     =                   \
                                "));

Open your chrome console, copy/paste it, and you get an alert.
