This plugin allow you to add Ruby interpreters available through the Debian alternatives system into rbenv. This means you can install the different Ruby interpreters through APT on Debian and derivative distributions, and switch between them using rbenv.
The Ruby interpreters installed via APT will become available to use with rbenv
in addition to any other Ruby interpreter you may have installed into
~/.rbenv/versions in any other way.
This plugin also install hooks that configure Rubygems to install gems inside ~/.rbenv/${version}/gems. This way you get completely separated Ruby environments.
If you have installed rbenv from source into ~/.rbenv, just create a symbolic link to where you downloaded this plugin inside ~/.rbenv/plugins:
$ mkdir ~/.rbenv/plugins
$ ln -s /path/to/rbenv-alternatives ~/.rbenv/plugins
If you install rbenv through APT, then it will already bring this plugin with it:
# apt-get install rbenv
$ rbenv alternatives
$ rbenv versions
1.8.7-debian
1.9.2-debian
$ rbenv global 1.9.2-debian
$ rbenv version
1.9.2-debian (set by /home/terceiro/.rbenv/global)
$ ruby -v
ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-linux]
Whenever you install a new Ruby interpreter, or uninstall a previously
installed one, just run rbenv alternatives again and it will update your
list of Debian-provided Ruby interpreters with rbenv.
