I’d like to define some custom environments for my users, in Nix. Currently I use mkDerivation and have them
nix develop it. This is working, but it results in a very cluttered environment, with all kinds of variables set related to phases, input lists, etc— basically it’s definitely a build-a-specific-package environment and I’d like to have more control over it than I seem to.
It looks like
nix shell may be a closer solution, as it only sets the
PATH. But I need to set a few other variables, and it doesn’t seem like postHook, setupHook, or shellHook get called when using
I could just launch the shell myself with a script invoked from
nix run, or even just build the script with
nix build and ask users to manually source it afterward in their shells. But I’d like to be able to use something a bit more built-in than that if it exists.
