A golang port of the awesome jsbeautifier tool

This is a port of the awesome jsbeautifier tool to golang.

Granted this is a very basic and naive attempt since this is one of my first takes with golang.

Current state

Implemented most of the original features from jsbeautifier (missing features are listed in the following section).

What doesn't work

  • Unpacking & Deobfuscation (and with that code eval)
  • Reading from stdin

Priority

  1. Finish implementing features to match the current state of JsBeautifier
  2. Unpacking & Deobfuscation

Usage

go get && go run main.go test.js

Testing

From within the source folder run: go test ./... or use something like goconvey
