It used to be that `nix-shell -A hello` would launch the build shell for the `hello` package. By adding `/shell.nix`, that stopped working, as all versions of `nix-shell` resolve the unspecified file to `$PWD/shell.nix` if it exists, and now it does. I have to admit that this use of `//` is not pretty, but the UX/DX hard to match.

# A shell to get tooling for Nixpkgs development
|
|
#
|
|
# Note: We intentionally don't use Flakes here,
|
|
# because every time you change any file and do another `nix develop`,
|
|
# it would create another copy of the entire ~500MB tree in the store.
|
|
# See https://github.com/NixOS/nix/pull/6530 for the future
|
|
#
|
|
# Note: We use a pinned Nixpkgs so that the tools are readily available even
|
|
# when making changes that would otherwise require a new build of those tools.
|
|
# If you'd like to test out changes to the tools themselves, you can pass
|
|
#
|
|
# nix-shell --arg nixpkgs ./.
