Show the services, factories, filters, directives, controllers etc exported by an angular module (by regexing the source)

#!/usr/bin/env ruby

# Reads your JS on STDIN, minified JS is OK as angular methods names should be preserved.
# The reason this exists is because I was getting an erroroneous error message about missing
# module 'ngLocale', but googling that indicated that it really meant that one of my dependencies
# was unresolved. A change to the JS concatenation had caused this error.

# In order to resolve the error I wrote a script to parse the old minified and new minified JS to dump
# declared services to STDOUT. I could then see what was missing.

# Prints out something like the following:

# SERVICE
#   sportsBetBuilderService
# FACTORY
#   BaseSportsBetBuilderState
#   BetSlip
#   ConfirmState
#   InterceptedState
#   InterceptRejectedState
#   RejectedState
#   SoldState
# CONSTANT
#   $moment
# VALUE
# CONTROLLER
#   ngModel
#   ngModel
# FILTER
#   dateOnly
#   timeOnly
