Source complete env in `nix-shell` with `__structuredAttrs = true;` This is needed to push the adoption of structured attrs[1] forward. It's now checked if a `__json` exists in the environment-map of the derivation to be openend in a `nix-shell`. Derivations with structured attributes enabled also make use of a file named `.attrs.json` containing every environment variable represented as JSON which is useful for e.g. `exportReferencesGraph`[2]. To provide an environment similar to the build sandbox, `nix-shell` now adds a `.attrs.json` to `cwd` (which is mostly equal to the one in the build sandbox) and removes it using an exit hook when closing the shell. To avoid leaking internals of the build-process to the `nix-shell`, the entire logic to generate JSON and shell code for structured attrs was moved into the `ParsedDerivation` class.

export NIX_BUILD_SHELL=$SHELL
env NIX_PATH=nixpkgs=shell.nix nix-shell structured-attrs-shell.nix \
Set environment variables for .attrs.json & .attrs.sh This way no derivation has to expect that these files are in the `cwd` during the build. This is problematic for `nix-shell` where these files would have to be inserted into the nix-shell's `cwd` which can become problematic with e.g. recursive `nix-shell`. To remain backwards-compatible, the location inside the build sandbox will be kept, however using these files directly should be deprecated from now on.

Add testcase for `nix develop` with `__structuredAttrs`
2021-05-18 13:07:30 +00:00
# `nix develop` is a slightly special way of dealing with environment vars, it parses
# these from a shell-file exported from a derivation. This is to test especially `outputs`
# (which is an associative array in thsi case) being fine.
nix develop -f structured-attrs-shell.nix -c bash -c 'test -n "$out"'
