How to Update Your Pry Prompt Setting since v0.13.0

The pry gem changed itsPry::Prompt API since v0.13.0, and deprecated setting prompt through Pry.config.prompt = [] . If you have customized this way, you should use the new API instead.

If you have set up your pry prompt like this way:

# config/initializers/pry.rb

# Show red environment name in pry prompt for non development environments
unless Rails.env.development?
  old_prompt = Pry.config.prompt
  env = Pry::Helpers::Text.red(Rails.env.upcase)
  Pry.config.prompt = [
    proc {|*a| "#{env} #{old_prompt.first.call(*a)}"},
    proc {|*a| "#{env} #{old_prompt.second.call(*a)}"},
  ]
end

You could use the new API like this:

unless Rails.env.development?
  default_prompt = Pry::Prompt[:default]
  env = Pry::Helpers::Text.red(Rails.env.upcase)
  Pry.config.prompt = Pry::Prompt.new(
    'custom',
    'my custom prompt',
    [
      proc{ |*args| "#{env} #{default_prompt.wait_proc.call(*args)}" },
      proc{ |*args| "#{env} #{default_prompt.incomplete_proc.call(*args)}" },
    ],
  )
end
