# package https://gitlab.com/tahoe-lafs/pycddl
#
# also in the process of being pushed upstream
# https://github.com/NixOS/nixpkgs/pull/221220
#
# we should switch to the upstream package when it is available from our
# minimum version of nixpkgs.
#
# if you need to update this package to a new pycddl release then
#
# 1. change value given to `buildPythonPackage` for `version` to match the new
# release
#
# 2. change the value given to `fetchPypi` for `sha256` to `lib.fakeHash`
#
# 3. run `nix-build`
#
# 4. there will be an error about a hash mismatch. change the value given to
# `fetchPypi` for `sha256` to the "actual" hash value report.
#
# 5. change the value given to `cargoDeps` for `hash` to lib.fakeHash`.
#
# 6. run `nix-build`
#
# 7. there will be an error about a hash mismatch. change the value given to
# `cargoDeps` for `hash` to the "actual" hash value report.
#
# 8. run `nix-build`. it should succeed. if it does not, seek assistance.
