[Courses] [Ruby] Lesson 0: Installing

[Anne G]

Hi

I started thinking about lesson 1, but I am spending most of
my time reading about set ups.

I would like to look at ruby class methods, but I have not
figured out how to do that. there is something called ri
which is a terminal program but I have not really figured
out how to use it to look at class methods, what they do...

could someone post some examples of how to use ri, or any
other tool that would be useful in that regard?

for objective C there was a nice little application
AppKiDo 0.94 which let you look at classes, methods...

In xcode there were ways to use key combinations to find
definitions... What is the best way -- beside the book which
should come next week -- to find out information

-------------------------------------------------------

I have also been thinking about GUI and how to do that in
Ruby for a web application. I found an example using tk

Here is the snipet I found which makes a button:

require 'tk'
root = TkRoot.new
button = TkButton.new(root) {
  text "Hello,Anne"
  command proc { puts "I said"}

}

button.pack
Tk.mainloop

It runs on ruby terminal, but it does not run on rubycocoa,
and it does not run on emacs.

I would really like to be set up in an environement where I
don't have to use terminal and unix commands. I would like
to use mac applications, mac windows and editors. I don't
know what to do to get a set up I will be able to use with
GUIs if this basic one does not work!

Any idea why rubycocoa and emacs don't find tcltklib?
It is a directory in ext in the ruby 1.8.3 source file, but
I don't know what happens to it during install or how to
set up a mac path so ruby finds it in those other
environments

------------------------------------------------------

In addition, I got a response which suggest GUIs are quite
complex and I don't know which package I should use, if it
is set up by default or not...

Here is the response:
> rubycocoa is the Ruby interface bindings to the native

What guis will we be using for this course?

thanks for any help you can give me.
