Can ruby comment out a block of code???

Roseanne Zhang

It sounds pretty stupid, but I could not find a way to do it in Ruby
yet.

Such in C/C++/Java:
/*
This is all comments.

people. Before you post, please use the FAQ, the Ruby documentation and
Google to find an answer to your question. If you can't find an answer
there, make sure to include all relevant information that is necessary
to help you in your post.
*/

Am I missing something???

Help, please!

Ruby's block comment looks like this:

=begin

We're in a comment here. Both the =begin and the =end must be the
first elements on a line for this to work.

=end

$ acroread Programming\ Ruby.pdf

Search for =begin

Page 218:
</do this>

Looks like a line starting with "=begin" and a line starting with "=end"
will comment out a chunk of code.

Are there any plans on introducing shorter form in ruby 2?

The form isn't that much of a problem, but the fact that something like
that isn't possible

puts "hey" =begin
comment
=end

Using all pound signs is more common - I only see the =begin / =end
style for file headers. Just Learn To Use Your IDE/Editor, and use
whicheverkeycombo it provides for line-commenting a paragraph, and
letting you span such a comment over multiple lines easily. I -think-
ruby-mode for Emacs supports auto-fill for that. Might be thinking of
another language though.
