If you're like me, you write a ton of HTML+CSS when doing web development, and write all the javascript later. Point this script at your html files to automatically generate function declarations. NOTE: move the script file after use, because it will be destroyed each time

jsfunctionbuilder.rb

#coded by michael ward
#i wrote a bunch of client facing code to render different stuffs
#and decided to write all the javascript functions later and 
#only focus on the CSS and HTML, and i realized it was a pain
#to go and get all the functions i needed to write, etc... so..
#voila

#*-------------------------------------------------*
#i want to port it to be able to take 1/2 argument *
#that would either a) read dirs for all html files *
#and then build all the js functions, and b) take  *
#an argument that specifies which language to build*
#the functions in OR which language to extract from*
#SO if you like that idea, stay tuned or fork      *
