Hi

I added case insensitive option to regex, so you can use it as /MLB/i

Thanks for helping improve logstash!

Code looks ok.

I'm not sure how this change fits into our plans for a management api, though, and I am hesitant to add further extensions to the config language until we figure out the path from today's config file to the future's management api.

As a workaround until we figure things out, folks can use the (?i) flag within the regexp to have the same effect: /(?i)this Is Case Insensitve/

Can one of the admins verify this patch?
