# Notes:

|
# Silvan (Tweag) covered some things on recursive attribute sets in the Nix Hour:
|
|
# https://www.youtube.com/watch?v=BgnUFtd1Ivs
|
|
#
|
|
# I (@connorbaker) highly recommend watching it.
|
|
#
|
|
# Most helpful comment regarding recursive attribute sets:
|
|
#
|
|
# https://github.com/NixOS/nixpkgs/pull/256324#issuecomment-1749935979
|
|
#
|
|
# To summarize:
|
|
#
|
|
# - `prev` should only be used to access attributes which are going to be overriden.
|
|
# - `final` should only be used to access `callPackage` to build new packages.
|
|
# - Attribute names should be computable without relying on `final`.
|
|
# - Extensions should take arguments to build attribute names before relying on `final`.
|
|
#
|
|
# Silvan's recommendation then is to explicitly use `callPackage` to provide everything our extensions need
|
|
# to compute the attribute names, without relying on `final`.
|
|
#
|
|
# I've (@connorbaker) attempted to do that, though I'm unsure of how this will interact with overrides.
