SciTe is not a compiler, it is an editor, learn the difference. Ruby does not have a compiler, it is interpreted through (guess what) and interpreter.

To run the program (if it is already not set up for automatic interpreting on double-click) you need to use the command line. In the folder where the source file is, type something like "ruby sourceFile.rb", I don't remember the specifics.

For more help, look here:

or check IRC (irc.afternet.org #compsci.ca) where someone may help you:

go to your command line (start -> run -> cmd)

from there
code:

ruby source_file.rb

or better yet
code:

irb

for some interactive shell action Wink
code:

N:\>irb
irb(main):001:0> puts "Hello Ruby!"
Hello Ruby!
=> nil
irb(main):002:0> exit

N:\>

Right, but Scite can execute the code and display it in the output pane. Very Happy

Search around the menus (File, Edit..). You might find it under Tools.

edit: But, don't let it steer you away from using irb. irb will be your best friend.

this 'irb' ... could i type a whole program in there, and then execute it? or does it just go line by line type deal?

im new to all this, only other language i learned was turing. all this talk about ruby, figure i may aswell jump in lol

A little of both. Smile

It will accept one piece of code that makes sense at a time. This might be a single line of code, but it might be more than one line.

code:
irb(main):001:0> 1 + 2
=> 3
irb(main):002:0> 1 +
irb(main):003:0*
irb(main):004:0* 2
=> 3
irb(main):005:0>


The other thing to keep in mind is that it remembers what has happened on previous lines.

code:
irb(main):005:0> foo = 42
=> 42
irb(main):006:0> puts foo
42
=> nil
irb(main):007:0>

how do you execute in SciTE though? i'm starting to learn Ruby (tired of Turing and its limitations) because ive heard many a good things about it, but i am unsure of how to run it Sad (yes i have read the above posts, but could someone explain it in a bit more of step-by-step thing plz Very Happy )
