Comment at the end of the line of a js file causes an error

[taktran]

I've tried running the app with a file which generates source maps, but it seems like uglifier fails when there is a comment on the last line of the js file. I get this error

{ [Error: Unexpected token: eof (undefined)]
  pos: 3258,
  col: 20,
  line: 117,
  filename: null,
  source: '...' }

where the file to obfuscate looks something like this

var __extends = this.__extends || function (d, b) {
    for (var p in b) if (b.hasOwnProperty(p)) d[p] = b[p];
    function __() { this.constructor = d; }
    __.prototype = b.prototype;
    d.prototype = new __();
};
// ...
var SomeClass = (function (_super) {
    __extends(SomeClass, _super);
    function SomeClass() {
        _super.call(this, true);
    }
    return SomeClass;
})(MessageDispatcher);
module.exports = SomeClass;
//# sourceMappingURL=SomeClass.js.map

(generated from the Typescript compiler, if you are interested)

If I remove the last line, it works fine. I'm guessing the uglifier parser doesn't expect comments at the end of the file.

fixed and released as 0.5.3

Works like a charm! Thanks!

Although, I've also removed source maps, as it's pretty redundant after obfuscating =)

glad it's working for you!

thanks for the bug report :)
