I find that writing a default.nix file or a shell.nix file for each
project that I work on gives me the best results.
As an example, below are some files that I've hacked up. I don't work
with Ruby that often anymore so my motivation to make these files better
isn't really there.
First, a function that uses its arguments to build a package/environment
for each application that I work on:
https://github.com/pjones/nix-utils/blob/master/lib/ruby/default.nix
And here is an example application using that function:
https://github.com/pjones/nix-utils/blob/master/envs/rfa/cltc-phoenix.nix
The way I use this is by running `nix-shell`, giving it the above file,
while in the directory of the application. It drops me into a shell
that has everything I need to work on a Ruby/Rails application.
