Hello Guys ,

Can anyone explain me how to use Oniguruma in ruby 1.9.2 , I guess in ruby 1.9.2 its a default library so there is no need to install externally?

I was using Oniguruma::ORegexp.new( in ruby 1.8.7 .

Thanks Nishant

Onigurama is the regular expression engine for 1.9.x - /foo/ will use onigurama

I think it's all backwards compatible - your existing regular expressions should still work, but you now also have access to more features. Do you have any particular examples of things that aren't working as you expect?

I changed Oniguruma::ORegexp.new with Regexp.new

for example contents.to_s.gsub!(regular_expression, replace text) but it returns a nil value and does`nt seem to working as expected

like (<\/p>)\s+(<p>) for removing paragraph tags form the content

and i keep recieving this error message in the terminal
