Ruby Pocket Reference

Comments

A comment hides a line, part of a line, or several lines from the Ruby interpreter. You can use the hash character (#) at the beginning of a line:

# I am a comment. Just ignore me.

Or, a comment may be on the same line after a statement or expression:

name = "Floydene" # ain't that a name to beat all

You can make a comment run over several lines, like this:

# This is a comment.
# This is a comment, too.
# This is a comment, too.
# I said that already.

Here is another form. This block comment conceals several lines from the interpreter with =begin/=end:

=begin
This is a comment.
This is a comment, too.
This is a comment, too.
I said that already.
=end

A block can comment out one line or as many lines as you want.
