Rails using byebug inside a proc?

I am trying to use byebug/debugger inside a proc that gets called later with threads, but its not working. So how can I Debug code inside a proc?

Solution

  • You have to ensure that the thread inside which you are adding the breakpoint eventually calls join.

    e.g.:

    myproc = Proc.new do
  Thread.new do
    require 'pry'; binding.pry
  end.join
end

myproc.call

    will stop at the breakpoint.

    Whereas

    myproc = Proc.new do
  Thread.new do
    require 'pry'; binding.pry
  end
end

myproc.call

    will not
