The roboto font repository has not been update since 2017, and
recently it has been archived.
Roboto Flex is its continuation, in a brand new repository.
See https://github.com/googlefonts/roboto-flex for more information.
Maintainers of packages that depend on roboto should consider
migrating them to using roboto-flex.
We are migrating packages that meet below requirements:
1. using `callPackage`
2. called path is a directory
3. overriding set is empty (`{ }`)
4. not containing path expressions other than relative path (to
makenixpkgs-vet happy)
5. not referenced by nix files outside of the directory, other
than`pkgs/top-level/all-packages.nix`
6. not referencing nix files outside of the directory
7. not referencing `default.nix` (since it's changed to `package.nix`)
8. `outPath` doesn't change after migration
The tool is here: https://github.com/Aleksanaa/by-name-migrate.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

- stop binding attributes we don't care about (e.g. name, doCheck)
- remove attributes we handle in nix (e.g. useAppHost)
- inherit attributes with default values (e.g. packNupkg)
