IrbReload

IrbReload is a lightweight library for reloading code in an IRB session. It's a great tool for gem authors while a gem is under active development.

Installation

Add this line to your application's Gemfile:

# most likely in a :development group
group :development do
  gem 'irb_reload'
end

And then execute:

$ bundle

Or install it yourself as:

$ gem install irb_reload

Usage

After installing, add the following this line to your ~/.irbrc file:

require 'irb_reload'

Or, if you prefer, simply require 'irb_reload' when you start an IRB session.

Assuming your IRB session was started in the root directory of your project, IrbReload will find and reload all your project's classes and constants, even under multiple namespaces.

Just like Rails console, just type:

reload!

and you're good to go!

Interpreter Compatibility

IrbReload is compatible with MRI 1.9 and 2.0 and has been tested on JRuby 1.7.3

Caveats

• IrbReload expects you to start your IRB session in the root of your project.
• Due to the above, It probably won't work if you change the cwd of your Ruby process, i.e. Dir.chdir 'lib/'
• IrbReload assumes you're following basic Ruby conventions regarding your directory structure. see this link
