Alternative approach to converting CSON (CoffeeScript Object Notation) to JSON (JavaScript Object Notation) which does not require outer curly brackets to be present in the CSON.

gistfile1.coffee

fs = require 'fs'
path = require 'path'
coffeeScript = require 'coffee-script'

convertCSON = (csonObject) ->
  return unless csonObject?

  completeObject = 
    "csonObject = {
       #{csonObject}
     }"

  compiledObject = coffeeScript.compile completeObject, {bare: true}
  new Function("#{compiledObject}; return csonObject;")()

convertCSONFile = (filename, callback) ->
  fs.readFile filename, (err, data) ->
    throw err if err

    callback convertCSON(data)

convertCSONFileSync = (filename) ->
  fileData = fs.readFileSync filename, 'utf-8'
  convertCSON fileData

exports =
  convertCSON: convertCSON
  convertCSONFile: convertCSONFile
  convertCSONFileSync: convertCSONFileSync
