Reapplies #517762, reverted in #518791.
Pass config = {} explicitly to prevent impure.nix from filling it
from NIXPKGS_CONFIG. This is equivalent to the old behavior where
inherit (cfg) config always overrode the impure.nix default.
Add a Hugging Face Hub repository fetcher with support for model, dataset, and space repositories, custom Hub domains, tags and revisions, and the relevant fetchgit options.
Select storage through a backend argument. Git LFS is implemented through fetchgit; Xet is the default to match Hugging Face but fails explicitly until its implementation lands.
Expose the helper from pkgs, document its API, and register evaluation and fixed-output fetch tests.

Test that wrapQtAppsHook:
- normalizes qtWrapperArgs to a bash array
- preserves user-supplied wrapper arguments
- appends the expected Qt wrapper arguments
- produces wrappers with the expected runtime behaviour
Switch the option type to `deferredModuleWith`, which collects definitions without evaluating them.
The raw definitions are forwarded to nixpkgs function via a new internal `_configDefinitions` parameter.
`apply` on the option returns `finalPkgs.config`, preserving
backwards compatibility for external readers of `config.nixpkgs.config`
If the lockfile is empty, no files will be put in the output directory.
In this case, the find invocations produce an empty list of results.
xargs' default behaviour is to always invoke its command at least once;
if its input is empty, then its command will not be passed any
filenames. This produces an invocation like `chmod 555`. chmod, however,
fails in this case, expecting an operand. So we need to tell xargs not
to invoke its command at all in the case of empty input.
Verifies that buildLakePackage works with nix-only deps (no
lake-manifest.json). Builds a proof of the weak minimax inequality
from Mathlib.Order.CompleteLattice.Basic using leanDeps = [ mathlib ].
Add an eval-time test harness for buildEnv following the pattern established by `tests.overriding`.
Uses `lib.runTests` to compare expr/expected pairs, and the buildCommand reports pass/fail.
No tests yet; subsequent commits add them individually.
This adds a test for the --structured-log feature of auto-patchelf.
When auto-patchelf'ing ToneLib-Jam and only making freetype available,
we expect:
- one "SetInterpreter" line
- 3 "Dependency" lines (of which one found)
- one SetRpath line (containing freetype)
This attribute was supposed to be set on derivations, to make the
release tools recurse into them. The remaining uses were all on regular
attrsets, though, so this is safe to remove.
