Can I import/require OpenStudio SDK (Ruby bindings) into IRB?

edit

As Kyle mentioned, there is a way to customize the irb startup configuration. You have to do the following (assuming Mac or Linux):

If ~/.irbrc does not exist, call touch ~/.irbrc to create it.

Then inside ~/.irbrc you can put

// I think this is the correct pathing    
require "/Applications/OpenStudio 1.10.0/Ruby/openstudio.rb"
require 'irb/completion'

or what I have in my ~/.irbrc file (other than different openstudio.rb path for my dev build)

IRB.conf[:AUTO_INDENT] = true
IRB.conf[:USE_READLINE] = true
IRB.conf[:LOAD_MODULES] = [] unless IRB.conf.key?(:LOAD_MODULES)
unless IRB.conf[:LOAD_MODULES].include?('irb/completion')
  IRB.conf[:LOAD_MODULES] << 'irb/completion'
end
require "/Applications/OpenStudio 1.10.0/Ruby/openstudio.rb"

This will automatically load completion and openstudio everytime you call irb on command line.

I specify the paths on the command line like this (on Windows for version 1.10.0):

C:\Users\jdegraw>"C:\Program Files\OpenStudio 1.10.0\ruby-install\ruby\bin\irb" -I "C:\Program Files\OpenStudio 1.10.0\Ruby\openstudio"

I like doing it this way because it also works for my development build if I change out the paths.

For the sake of using the official documentation out there, specifically the "Getting Started" tutorial:

Optional - Install Ruby If you plan to use the OpenStudio SDK Ruby bindings via command prompt on Windows, you must install Ruby. OS X already has Ruby installed.

Download the Ruby 2.0.0 installer. If you have the Windows (x64) version of OpenStudio (Help>About>Compiler shows Visual Studio 12 2013 Win64), you'll need the x64 Ruby installer. If you have the Windows (x32) version of OpenStudio, you'll need the non-x64 Ruby installer.
Add `C:\Ruby200\bin` (or wherever you installed Ruby) to the PATH environment variable. Detailed instructions.

Create a text file with the following text inside:

`require 'C:\Program Files (x86)\OpenStudio 1.7.0\Ruby\openstudio.rb'`

Save the file as `openstudio.rb` here: `C:\Ruby200\lib\ruby\site_ruby\openstudio.rb` (next to the 2.0.0 folder).
Test your installation by opening a command prompt and typing: irb ENTER. Then, type require 'openstudio ENTER. If you see some QSslSocket messages and => true, it's working.

I personally have several of these files in there, usually two: openstudio.rb which points to the latest stable release, and openstudio-rc.rb which points to a release candidate. This way I can require any of these two as needed.
