bug:Unhandled exception: Not Implemented: Crystal::System::Signal.trap (NotImplementedError) from D:\Dev\Crystal\src\crystal\system\win32\signal.cr:5 in 'trap' about kemal HOT 2 CLOSED

I remember Kemal implementing the platform agnostic trapping, but now when I view the source code it seems like it might have been lost in commits.

Anyway you can extend the Kemal module for now for a temporary fix

module Kemal
  private def self.setup_trap_signal
    Process.on_interrupt {
      Kemal.stop
      exit
    }
  end
end

Save this into a file named extension.cr and require it right after you require the Kemal lib, for example:

require "kemal"
require "./extension.cr"

I will make a PR to fix this issue.

from kemal.

Should be fixed by #666
