I've written such a script a while ago: https://gist.github.com/aherrmann/51b56283f9ed5853747908fbab907316 It places the gcroots in separate folders under `~/.nix-shell`. If you run it as `pnix-shell -c` it will reevaluate the Nix expression. This way you can enforce updates. _______________________________________________ nix-dev mailing list [email protected] http://lists.science.uu.nl/mailman/listinfo/nix-dev
