I am trying to use the Marginalia gem's :line parameter. It emits something, but it seems to always say 'script/rails:6', as in...
This is at the top of application.rb:
require File.expand_path('../boot', __FILE__)
And this is in config/initializers/marginalia.rb:
Marginalia::Comment.components = [:application, :controller, :action, :line]
Do I need to add a permissive regex to include much more of the backtrace so line yields something useful?
