17:03 <sheijk> how do people handle development environments with nix? like having an emacs configured with the right plugins as a nix expression so i can get back to a working env for an old project etc.

17:04 <dash> `nix-shell my-dev-env.nix` typically

17:04 <sheijk> i've managed to have an emacs dir with a default.nix which uses the parent nix expr and installs developer tools, emacs plugins etc. But i don't see any projects on the web doing something like this. so is there a better way?

17:06 <sheijk> ok, i see. guess i'll keep it that way then, thanks

17:21 <selfsymmetric-mu> sheijk: Hmmmmm, you're configuring Emacs itself with Nix? Interesting. I have a global Emacs that uses Nix to install other tools, using direnv integration. I suppose you could do it your way and build a new Emacs for each environment, but that doesn't seem to provide much of a benefit.

17:22 <selfsymmetric-mu> I mean, I configure Emacs with Nix too, but I do it globally. I don't build a new Emacs for each project.

18:07 <sheijk> i had some compatibility issues where my normal package.el based config caused problems with ocaml tools. could have been an unlucky combination of versions. moving emacs inside nix and having one for each project solved that. i take care to base everything on 20.09 stable so the main emacs package will not be installed in several versions

18:23 <selfsymmetric-mu> Iiiinteresting. OCaml is tricky, especially with Nix.
