This allows for adding new, conditionally set, derivation attributes
to an existing derivation without changing any output paths in the
case where the condition is not met.
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`.
For transforming back between lists and attrsets, it makes sense to have
a quasi-inverse of `builtins.listToAttrs` available as a library
function.

Deeply-curried functions are pretty error-prone in untyped languages
like Nix. This is a particularly bad case because
`top-level/splice.nix` *also* declares a makeScopeWithSplicing, but
it takes *two fewer arguments*.
Let's add a version that uses attrset-passing form, to provide some
minimal level of sanity-checking.
This also provides defaults for keep and extra (these are often
unneeded by the user).
no longer supported. warning when used would not be appropriate, and
docbook has been on the way out for long enough that throwing an error
should not be necessary either.
mkAliasOptionModule should not default to mdDoc descriptions because
that can break out-of-tree users of documentation infrastructure. add an
explicitly-MD variant for now, to be removed some time after the MD
transition is complete.
This reverts commit PR #167947.
Flakes aren't standardised and the `lib` namespace shouldn't be
polluted with utilities that serve only experimental uses.
This commit creates flakes.nix, which is a library containing functions
which relate to interacting with flakes. It also moves related functions
from trivial.nix into it.
This is essentially a copy of the function of the same name, from
flake-compat. callLocklessFlake is useful when trying to utilise a
flake.nix without a lock file, often for when you want to create a
subflake from within a parent flake.
