Rerun + Pry = ☠

[TrevorBramble]

Hi, I had occasion to use Pry last night in a project I was relying on Rerun to serve and found it makes Pry almost impossible to use.

Rerun appears to be monitoring all keyboard input, including at the Pry prompt, so it will react to certain characters (t, x, etc.) and ignore backspace, arrows, and such.

Should I just not expect them to work together?

I recorded a short demo. Here are its files:

# Gemfile
source "https://rubygems.org"

gem 'rack',  '1.6.4'
gem 'rerun', '0.11.0'
gem 'pry',   '0.10.3'

# config.ru
require 'bundler'
Bundler.require

run -> (env) {
  binding.pry
  [200, {'Content-Type' => 'text/plain'}, ['']]
}

$ ruby -v
ruby 2.2.3p173 (2015-08-18 revision 51636) [x86_64-linux]

Rerun invoked with:

$ rerun -- rackup

If you want to use the keyboard within the script, use the --background (or -b) flag on rerun. This doesn't put rerun into the background, but allows it to be - or allows you to use the keyboard for other things.

$ rerun -b -- rackup
