Sandbox

DESCRIPTION:

Inspired by Python's virtualenv project, Ruby-Virtualenv is a utility to create sandboxed Ruby/Rubygems environments.

It is meant to address the following issues:

  • Conflicts with unspecified gem dependency versions.
  • Applications can have their own gem repositories.
  • Permissions for installing your own gems.
  • Ability to try gems out without installing into your global repository.
  • A Simple way to enable this.

Running from your own gem repositories is fairly straight-forward, but managing the necessary environment is a pain. This utility will create a new environment which may be activated by the script bin/activate in your sandbox directory.

Run the script with the following to enable your new environment:

$ source bin/activate

When you want to leave the environment:

$ deactivate

NOTES:

  • It creates an environment that has its own installation directory for Gems.
  • It doesn't share gems with other sandbox environments.
  • It (optionally) doesn't use the globally installed gems either.
  • It will use a local to the sandbox .gemrc file

FEATURES/PROBLEMS:

Activating your sandbox environment will change your HOME directory temporarily to the sandbox directory. Other environment variables are set to enable this funtionality, so if you may experience odd behavior. Everything should be reset when you deactivate the sandbox.

USAGE:

Create a new virtualenv (verbose output by default):

$ ruby-virtualenv ~/.ruby-virtualenvs/my-new-sandbox
creating new sandbox in /home/nkryptic/ruby-projects/my-new-sandbox
installing activation script
installing .gemrc
installing gems:
  nothing to do

Create a new sandbox with no output:

$ ruby-virtualenv ~/.ruby-virtualenvs/my-new-sandbox -q

Create a new sandbox with specific gems:

$ ruby-virtualenv ~/.ruby-virtualenvs/my-new-sandbox -g rake,rails
creating new sandbox in /home/nkryptic/ruby-projects/my-new-sandbox
installing activation script
installing .gemrc
installing gems:
  gem: rake
  gem: rails

FUTURE PLANS:

I hope to expand the full version branch to allow for installing both rubygems and ruby as part of the sandbox. This would enable experimentation with different versions of both and exclude the requirement on needing rubygems in the first place.

REQUIREMENTS:

  • ruby
  • rubygems

INSTALL:

$ gem install ruby-virtualenv
