I’m messing around with the edge of the Merb 0.9 developer release and Haml. I have very little experience in Haml and I’ve never used Merb before, so it’s probably a bad idea to start off with a developer release but hey whatever. I could not get the form_tag function from merb_helpers to work. This…

%p
  This will be the most basic DNS lookup ever

- form_tag(:action => url(:controller => :dns, :action => :index)) do
  = text_control "target", :label => "Domain/IP"

Gave me this…

undefined local variable or method `_buf' for # - (NameError)

I wasn’t sure if I was using Haml wrong, Merb wrong, or both. Google indexed an error log of the exact same problem and a few minutes later the bug entry which was entered just 45 minutes before I found it.

That’s just crazy cool.
