[Nix-dev] non-constant path expressions

[Merijn de Jonge]

Hi,


I would like to make more "generic" nix expressions in for packagesfor 
which many versions exist, e.g., aterm.

I would like to make the version an argument for the nix expression in 
aterm/default.nix:

   {stdenv, fetchurl, version ? 1.3.4}:
    (import ./aterm- ++ version ++ .nix) {
   inherit stdenv fetchurl
}


and then create a separate nix expression aterm-version.nix for each 
existing aterm version.

Is something like this already possible? If not, what do you think about 
this as a new feature?


Thanks,
Merijn
