[Nix-dev] Re: Ruby-gems

[Pjotr Prins]

The Ruby gems problem is similar - and I agree with your assessment
of wrappers providing paths.

I am thinking - eventually - a solution would be to embed the
installation of an add-on into a proper nix-build. Each add-on would
just become its own package. With Ruby gems that is feasible, I think.

'nix-gem install add-on.gem' would need to put the build and
installation within nix-build. That way Nix is aware and can manage
the environment. Only thing, as we don't know a gem beforehand, would
it be possible to generate a nix expression on the fly?

Or is that inadvisable?
