* Rails, GNU Guix demo

This repository is a really quick example of how to use Ruby on Rails
with GNU Guix. Most Ruby on Rails applications will probably use a
combination of Rubygems and Bundler to manage some of the
dependencies, but it's possible to substitute Guix packages for
Bundler, to gain some of the advantages of working with GNU Guix.

To try this out, you'll need to:

 - ~git clone https://git.cbaines.net/rails/guix-demo~
 - ~git submodule update --init~
 - Setup the guix submodule, some instructions here:
   https://www.gnu.org/software/guix/manual/en/guix.html#Building-from-Git
 - Use =direnv= to setup the environment correctly, or run:
   ~./guix/pre-inst-env guix environment --ad-hoc ruby ruby-rails~
 - Then run ~rails s~ from =testapp=

Once Ruby on Rails support is in Guix properly (rather than a branch),
this should hopefully be easier. This bug [1] tracks the overall
progress, but other bugs are used for subsets of the patches. If you
have any problems, email mailto:mail@cbaines.net.
