Okay,
so just went to my first ruby class and its way over my head.

now, i know html, and i know some php, but im not a coder at all,
and so im gonna need some help here.

Where do i get started.
Ive got ruby downloaded and installed, and my class is using alot of irb to do all of this stuff.

so how do i use irb.
professor typed in some code and opened up something with file and save and all those good options on a nav bar at the top. but i have no idea how to do that,

im stuck in basic cmd with irb turned on.
does that even make sense?



also, tell me this
what changes do i need to make if im coding on a windows machine and its gonna have to run on either a unix or osx system.

Well, Irb can be used in many ways...are there particular functions you'd like to use it for? The PPG has a good section on using the Irb:
http://www.rubycentral.com/book/html/irb.html

as does rubygarden:
http://wiki.rubygarden.org/Ruby/page/show/Irb/TipsAndTricks

As for platforms, ruby is pretty much cross platform unless you're accessing platform dependant objects, such as specific file types, browser objects, etc...

Irb is merely a console and not the best when it comes to editing or saving files. If you want to stick to something console-ish, go with vim and simply have multiple shells open. If you're on windows, use a simple text editor. When you update your file, use the load command to reload your saved file. Don't use require since that only loads it once.
