Co-authored-by: Robin Gloster <mail@glob.in> stdenv: print message if structuredAttrs is enabled stdenv: add _append reduces the chance of a user doing it wrong fix nix develop issue output hooks don't work yet in nix develop though making $outputs be the same on non-structuredAttrs and structuredAttrs is too much trouble. lets instead make a function that gets the output names reading environment file '/nix/store/2x7m69a2sm2kh0r6v0q5s9z1dh41m4xf-xz-5.2.5-env-bin' nix: src/nix/develop.cc:299: std::string Common::makeRcScript(nix::ref<nix::Store>, const BuildEnvironment&, const Path&): Assertion `outputs != buildEnvironment.vars.end()' failed. use a function to get all output names instead of using $outputs copy env functionality from https://github.com/NixOS/nixpkgs/pull/76732/commits
