Robert Hensing 4e7592b593 flake check: Recognize well known community attributes
This avoids warning fatigue, making `nix flake check` more effective.

John Ericson 5ba6e5d0d9 Remove default constructor from OutputsSpec
This forces us to be explicit.

It also requires to rework how `from_json` works. A `JSON_IMPL` is added
to assist with this.

John Ericson ce2f91d356 Split OutputsSpec and ExtendedOutputsSpec, use the former more
`DerivedPath::Built` and `DerivationGoal` were previously using a
regular set with the convention that the empty set means all outputs.
But it is easy to forget about this rule when processing those sets.
Using `OutputSpec` forces us to get it right.

John Ericson a7c0cff07f Rename OutputPath -> ExtendedOutputPath
Do this prior to making a new more limitted `OutputPath` we will use in
more places.

John Ericson 5576d5e987 Parse string context elements properly
Prior to this change, we had a bunch of ad-hoc string manipulation code
scattered around. This made it hard to figure out what data model for
string contexts is.

Now, we still store string contexts most of the time as encoded strings
--- I was wary of the performance implications of changing that --- but
whenever we parse them we do so only through the
`NixStringContextElem::parse` method, which handles all cases. This
creates a data type that is very similar to `DerivedPath` but:

 - Represents the funky `=<drvpath>` case as properly distinct from the
   others.

 - Only encodes a single output, no wildcards and no set, for the
   "built" case.

(I would like to deprecate `=<path>`, after which we are in spitting
distance of `DerivedPath` and could maybe get away with fewer types, but
that is another topic for another day.)

John Ericson da64f026dd Make clear that StorePathWithOutputs is a deprecated type
- Add a comment

- Put `OutputsSpec` in a different header (First part of #6815)

- Make a few stray uses of it in new code use `DerivedPath` instead.

Don't check NixOS modules
NixOS modules can be paths. Rather than dig further down into the layer
violation, don't check anything specific to NixOS modules.

Taeer Bar-Yam b13fd4c58e Fix why-depends for CA derivations
why-depends assumed that we knew the output path of the second argument.
For CA derivations, we might not know until it's built. One way to solve
this would be to build the second installable to get the output path.

In this case we don't need to, though. If the first installable (A)
depends on the second (B), then getting the store path of A will
necessitate having the store path B. The contrapositive is, if the store
path of B is not known (i.e. it's a CA derivation which hasn't been
built), then A does not depend on B.

build: use pkg-config for lowdown 2022-11-12 23:04:58 +01:00
Valentin Gagarin f7ab93b068 manual: build action -> build task
after discussing this with multiple people, I'm convinced that "build
task" is more precise: a derivation is not an action, but inert until it
is built. also it's easier to pronounce.

proposal: use "build task" for the generic concept "description of how
to derive new files from the contents of existing files". then it will
be easier to distinguish what we mean by "derivation" (a specific data
structure and Nix language value type) and "store derivation" (a
serialisation of a derivation into a file in the Nix store).
