Subject: Re: identifying and removing comments in a seprate ruby file

I wrote a simple one, maybe that's not so good.

$ cat 1.rb
# this is a comment

arr = [1,2,3,4]

# now loop through the array

arr.each {|s| puts s }

=begin
  author: somebody else
  date: 2010-12-12
=end


$ cat rmcomm.rb
lab=0
File.open("1.rb").each_line do |s|
   next if s=~/^#|^$/
   if s=~/^=begin/
      lab = 1
   elsif s=~/^=end/
      lab = 0
      next
   end
   next if lab == 1
   puts s
end


$ ruby rmcomm.rb
arr = [1,2,3,4]
arr.each {|s| puts s }
