if you are using rails you can use the simple_format function in your views.

here’s the source code from the api (http://api.rubyonrails.com/classes/ActionView/Helpers/TextHelper.html#M001057)

def simple_format(text)
content_tag ‘p’, text.to_s.
gsub(/\r\n?/, “\n”).
gsub(/\n\n+/, “\n\n”).
gsub(/([^\n]\n)(?=[^\n])/, ‘\1′)
end

Don’t understand why Ruby as a multi-purpose language directly should have such function/method.

If you using Rails web framework, there is a simple_format() method of ActionView::Helpers::TextHelper module that does exactly that and more.

Sorry, forgot to escape the br tag.

def nl2br(s)
s.gsub(/(\r)?\n/, “
”)
end

Don’t you think that it should be something like this:

def nl2br(s)
s.gsub(/(\r)?\n/, “”)
end

Windows has different way of breaking a line, that code will check also for the carriage return Windows used.

s.gsub didnt work for me alone, but

var = s.gsub(/\n/, ”)

did work. Just in case anyone else has the same problem

def nl2br(s)
s.gsub(/\n/, ”)
end

This would be more appropriate :)
