Lazy loading of Byebug

[bquorning]

I’m working on a project where we like to always have Byebug available in our test suite. But calling require 'byebug' in our spec helper adds 160ms to our RSpec startup time. And we want that number to be as low as possible.

Therefore, in our spec helper, I have defined this little hack:

def byebug
  require 'byebug'
  super
end

I’m wondering if we could implement something similar in Byebug itself, so I could just call something like require 'byebug/lazy' instead of the hack above?

Hi @bquorning. I understand your request. I have a macro in my editor myself that expands debug to require 'byebug'; byebug. :)

Perhaps we could even do this by default. require 'byebug' would just monkeypatch Kernel with the byebug method, and requiring the whole of byebug would be done inside the method.
