In this commit the possible options are just true or false to enable/disable eval source.

The > outputfile.js part is just stream redirection to ouput to file what the program is writing to standard output.

It's not all that different from your old version: I just check if the argv length is 4, and convert the argument to boolean (argv[2] === "true"), and pass that value to the JSFuck.encode function.

I needed this to create JSFucked files with the eval source option enabled.


var stream = require('stream');
var util = require('util');
var lib = require("./jsfuck.js");
var repl = require('repl');

if(process.argv.length !== 3) {
if(process.argv.length < 3 || process.argv.length > 4) {

function Stream() {
stream.Transform.call(this);
