Gsub and regex

ruby-talk
1

I'm trying to replace all /\n / with /\n/ in a string, but gsub won't allow a regex as the replacement when a match occurs. I'm getting myself considerably confused about data types and regex, and just plain need some help. Is there some way to do this replacement, using gsub?

Thanks,

t.

I'm not sure I understand you. Do you want to replace all newline charactes
followed by a space with a single newline character? If so, you don't need
regexps at all:

str.gsub("\n ", "\n")

I hope this helps

Man, this list is absolutely amazing. Here I am programming at 4:30 in the morning, and get stuck, and before I can execute my program again, I get my problem solved. I think I want to live in Ruby land the rest of my life.

And...how could I have forgotten that in "...." \n get understood. Jeez. So easy.

Thanks for being there.
