Here’s one stupid question:

How do you comment out a block of ruby code?

I know that “#” comments one line, but how do i comment out a block of  
7-8 lines of code? Don’t seem to be able to find this anywhere.

Thanks,

Gabor

There is no block comment, but some editors support easy multi-line  
commenting  
In TextMate, for instance, it’s the menu item  
Bundles\>Source\>Comment Selection.

There is block commenting:

=begin  
stuff to get commented  
=end

The tokens have to be flush to the left.

Sweet!

I just tried in SciTE and for it, it appears the ‘begin’ is opional but  
the  
‘end’ is required.

=  
stuff to get commented  
=end

Thanks Jason!
