Running two instances of Spork for two separate projects using Guard

00_README.md

Instructions:

• Take a look at the Guardfile here and copy and paste relevant parts.
• Install spork to script/spork
• Install drspec to script/drspec
• Remove --drb from your .rspec file. Using Spork has to be opt-in in order to properly customize the DRb port.
• Install .spork-port to .spork-port. Change the port to whatever you want.

01_Guardfile

spork_port = File.read(File.expand_path('../.spork-port', __FILE__)).to_i

guard 'spork', :rspec_port => spork_port do
  watch('Gemfile')
  watch('Gemfile.lock')
  watch('spec/spec_helper.rb') { :rspec }
  # ... whatever else you want here ...
end

rspec_config_file = File.expand_path('../.rspec', __FILE__)
rspec_opts = File.read(rspec_config_file).split("\n").join(" ")
guard(:rspec,
  :cli => "#{rspec_opts} --drb-port #{spork_port}"
  # ... whatever else you want here ...
) do
  watch(%r(^spec/(.+)_spec\.rb$))
  # ... whatever else you want here ...
end

02_spork

#!/bin/bash

spork_port=$(< .spork-port)
bundle exec spork --port $spork_port "$@"

03_drspec

#!/bin/bash

spork_port=$(< .spork-port)
rspec --drb --drb-port $spork_port "$@"

This works quite well so far. But what exactly does the script/drspec file? Where is it called?

And what does "Using Spork has to be opt-in in order to properly customize the DRb port." mean?

Let's discuss it here: guard/guard-spork#78 (comment)
