- Bring up to date
- Give meaning to the metavariables
- Use italics for metavariables (just like the Nix manual)
- Don't abbreviate
- No hard feelings, Val.
This is a follow-up to https://github.com/NixOS/nixpkgs/pull/325380 where @emilazy discovered that we have some typos in field names.
This refactoring wraps the implicit lib.licenses schema up in a factory function to ensure consistency.
While a more proper type checker like the one we use for meta checks would be better I didn't want to depend on that in more places.
In fact, we might want to make meta type checks more strict on the license field.
Previously we would fallback to using `kernel` as the `os` which would
result in using the wrong `os` value (`none`) when actually we want
`unknown`. This seems to be a special case for wasm32-unknown-unknown
and wasm64-unknown-unknown so I extended the if statement to support it.
All builtins should be in mirrored in lib, for consistency, as well
as control to let the Nixpkgs pin effect *subtle* improvements in
behavior (such as the foldl' accumulator strictness).
Benefits:
- some lookups happened in the hot path, and will now be slightly faster,
with only a variable lookup and no attribute selection
- it's now harder to accidentally use args.lib aka specialArgs.lib, which
has happened
- shorter
The practical use for this should be very limited because I don't
think anyone should change `lib`, let alone change `lib.functionArgs`,
but, but it would be even stranger to rely on `args.lib` (or really
`specialArgs.lib` for what's clearly a behavior of the current
`evalModules`, which uses its own ambient lib for basically everything.
The shadowing of `lib` by `args.lib` here seems to be a small mistake,
which is easy to make.
Add a library function to parse and validate an IPv6 address from a
string. It can parse the first two versions of an IPv6 address according
to https://datatracker.ietf.org/doc/html/rfc4291#section-2.2. The third
form "x❌x❌x:x.d.d.d.d" is not yet implemented. Optionally parser can accept prefix length (128 is default).
Add shell script network.sh to test IPv6 parser functionality.
