This reverts commit ce8f304bb6.
The problem was simply a typo (nestedTypes.elemType ->
type.nestedTypes.elemType) ! And CI didn't run for lib in the orginal
PR which is why it didn't get caught.
This gives people some flexibility when they need a path type, and
prevents a "combinatorial explosion" of various path stops.
I've re-implemented our existing `path` and `pathInStore` types using
`pathWith`. Our existing `package` type is potentially a candidate for
similar treatment, but it's a little quirkier (there's some stuff with
`builtins.hasContext` and `toDerivation` that I don't completely
understand), and I didn't want to muddy this PR with that.
As a happy side effect of this work, we get a new feature: the ability
to create a type for paths *not* in the store. This is useful for when a
module needs a path to a file, and wants to protect people from
accidentally leaking that file into the nix store.
Before this patch, code like this would break generate invalid XML:
lib.generators.toPlist {} "ab<cd"
That's obviously bad, since the call to toPlist often happens through
indirection, as is the case in e.g. the nix-darwin project. A user might
not realize that they have to escape the strings.
This patch adds the argument 'escape' to lib.generators.plist and emits
a warning if it is not set to true. In a future release, this behavior
should become the default.
I have also added a note for future maintainers, in case I forget to
actually remove the deprecated functionality in a future release.
After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

Add a new `aarch64-freebsd` double and example system,
then fix include and libc to work.
This is enough to build packages like `hello`,
either static or dynamic.
This is useful for testing nix FreeBSD on a Raspberry Pi.
When elaborating a system with both "config" and "system" arguments
given, they might not match the parsed results. Example:
elaborate {
config = "i686-unknown-linux-gnu";
system = "x86_64-linux";
}
This would result in a parsed system for i686, because the config
argument is preferred. But since "// args //" comes after system has
been inferred from parsed, it is overwritten again. This results in
config and parsed all pointing to i686, while system still tells the
story of x86_64.
Inconsistent arguments can also be given when passing "parsed" directly.
This happened in stage.nix for the various package sets.
The solution is simple: One of the three arguments needs to be treated
as the ultimate source of truth. "system" can already be losslessly
extracted from "parsed". However, "config" currently can not, for
example for various -mingw32 cases. Thus everything must be derived
from "config".
To do so, "system" and "parsed" arguments are made non-overrideable for
systems.elaborate. This means, that "system" will be used to parse when
"config" is not given - and "parsed" will be ignored entirely.
The systemToAttrs helper is exposed on lib.systems, because it's useful
to deal with top-level localSystem / crossSystem arguments elsewhere.
Probably a missed left over from somewhere in
the commit 58f385f680.
As can be seen in that commit where this line was introduced,
"$@" was also just emptied by the last `set` call in line 169.
This line is currently valid, but breaks suddenly when somewhere earlier
a `set --` instruction is used in the future.
Neither in commit 58f385f680
nor in PR https://github.com/NixOS/nixpkgs/pull/197547
have I found anything stating that this "defect" was intentional.
In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.
