How about a helper:
%p= error_helper(error)
def pre_code
open(:pre) do
open(:code) do
yield
end
end
end
def error_helper(error)
pre_code{puts error.backtrace.join("\n")}
end
I haven't tested this, but it should oughta work, and you can user
pre_code for any other plain-text stuff you want.
Thoughts?
