Overview

To install and use this:

  1. Recommended

Add 'pry' to your Gemfile (in the development group)
Add 'pry-debundle' to your Gemfile (in the development group)

  1. OK, if colleagues are wary of pry-debundle:

Add 'pry' to your Gemfile (in the development group)
Copy this file into ~/.pryrc

  1. Meh, if colleagues don’t like Pry at all:

Copy this file into ~/.pryrc
Create a wrapper script that runs `pry -r<your-application>`

  1. Pants, if you don’t like Pry:

Copy the definition of the debundle! method into your ~/.irbrc
Call 'debundle!' from IRB when you need to.

Class Method Details

.debundle! ⇒ Object

Break out of the Bundler jail.

This can be used to load files in development that are not in your Gemfile (for example if you want to test something with a tool that you have locally).

Normally you don’t need to cal this directly though, as it is called for you when Pry starts.

See github.com/carlhuda/bundler/issues/183 for some background.

Examples:

Pry.debundle!
require 'all_the_things'

.load_additional_plugins ⇒ Object

After we’ve escaped from Bundler we want to look around and find any plugins the user has installed locally but not added to their Gemfile.
