splitting up the dsl block

i love the way you have Fnordmetric.namespace :x do .. end - but is there a way to split this up to different ruby files?

it'd be cool to just include app/metrics/*.rb or something, and that would allow me to break it up by 'tab' in the app. Right now my metrics files run to 100s - 1000s of lines, and this makes debugging and such a bit nastier than it has to.

thanks!

I split DSL code between files like this:

# somewhere in initializer
def define_namespace(namespace)
  FnordMetric.namespace namespace do
    instance_eval(File.read(Rails.root.join("app/metrics", "#{namespace}.rb")))
  end
end

define_namespace(:user)
define_namespace(:performance)

Then just put content of namespace blocks in files in app/metrics:

# app/metrics/user.rb
gauge :sign_ups, :tick => 1.day.to_i, :title => "Sign ups"

That worked? I did something similar but it had only the effect of overwriting the namespace with the last file it found. :(

Ah I see it. i don't, however, want to split the namespace. maybe i will for the future i guess.
