Currently, the `lib/tests/modules.sh` test checks the output of
`nix-instantiate --eval` without `--json`, which outputs an unspecified
human-readable format.
This patch modifies `modules.sh` to use the `--json` output instead, to
be robust against future changes to `nix-instantiate` output.

While trying to extend generateLuarocksConfig, I had infinite loops caused by toLua considering derivations as attrSets

This commit temporarily adds pkgs/test/release to the
lib/tests/release.nix test suite, because ofborg already knows about
that entry point.
We should move the list of test entry points out of ofborg and into
a central place in nixpkgs:
https://github.com/NixOS/nixpkgs/issues/272591
Once we do that we won't need to have this ugly kludge in an
inappropriate place.

`lib.fileset.gitTracked,gitTrackedWith`: Minor improvements
|
|
|
|
|
|
Introduce an internal function for them to share more behavior.
This makes future changes easier.

flake: fix `lib.trivial.version` when used from a flake

We can create the `parse` function in a scope one level up to avoid recomputing it every time.

lib/modules: Test optionless module errors from #131205

* Improves the comments of `lib/flake-version-info.nix` and drops the
`__`-prefix from the filename.
* `lib'` -> `lib0` in `nixpkgs/lib`.
* Drop the declaration of `trivial.version` in the overlay because this
declaration already uses the final expressions of `versionSuffix` and
`release` now.
* No need to fall back to `self.lastModified` anymore, this was a
workaround for pre2.4 Nix.

That way each expression uses the final version of other lib.trivial
declarations.
For instance, when replacing `versionSuffix` with the string `"fnord"`
in a lib overlay, `trivial.version` uses `"fnord"` as suffix now rather
than `pre-git`.

doc: Rename to Nixpkgs reference manual and restate purpose

This effectively means that
nixpkgs$ nix eval ./lib#lib.trivial.version
"23.11.20231020.ee0d6b5"
now gives meaningful results as well.
See https://github.com/NixOS/nixpkgs/pull/257100#discussion_r1352075369
for the discussion around this.

Allows finding the most specific path that exists.
This is useful for error messages relating to attribute paths.

Probably not significant because of the limits already applied.
This is mostly cleanup.

A more efficient sort in some cases, and often convenient.
This exposes `lib.lists.sortOn` immediately on `lib`, because it is
a sibling of `sort`, which is already present there.
Omitting it would lead to more confusion, and worse outcomes.
There's no confusion about the types `sort` or `sortOn` operate on.
Haskell agrees about the type for `sortOn`, and it is in its `base`.
|
|
This type is necessary to have correct merging behavior for
`allowUnfreePredicate` and `allowInsecurePredicate`

For the time being, we're moving towards https://nix.dev/ containing
all tutorials and guides. The Nixpkgs manual is reinforced to be a
_reference_ manual. While it's not just reference for now, that's what
the docs team is working towards.
This commits rewrites the Nixpkgs manual introduction to reflect that
and point to some more useful links. The contribution docs are updated
similarly so it's not missed.

An important idea around the rust stuff in lib.systems is that it's
elaborated — this means that it should idempotently add to the values
passed in, if any. But we missed that the names used for the
parameter and the elaborated value for "rustcTarget"/"config" didn't
line up. The intention was to use "rustcTarget" everywhere in the new
interface, as a more descriptive name than "config".
This fixes setting the system in NixOS configuration, which results in
an already elaborated system being elaborated again. Before, this
wouldn't produce the correct result:
% nix-instantiate --eval -A stdenv.hostPlatform.rust.rustcTarget --system armv7l-linux
"armv7-unknown-linux-gnueabihf"
% NIX_PATH= nix-instantiate --eval -E '(import nixos/lib/eval-config.nix { system = "armv7l-linux"; modules = []; }).pkgs.stdenv.hostPlatform.rust.rustcTarget'
"arm-unknown-linux-gnueabihf"
