lib: use explicit name imports in `lib/generators.nix`
|
|
Avoid top-level `with` in `lib/tests/misc.nix`
|
|
|
|
submodules of `lib`
There's not a lot of rhyme to which names are exported from which module,
as I see it, but everything is found somewhere.
|
|
|
|
This enables further refactoring without accidentally changing the public interface.
|
|
Everything else was already imported.
|
|
Everything used was already imported.
|
|
A couple of these were imports from `builtins`.
|
|
I followed the `inherit` chains in `lib/default.nix` to arrive at these imports.
|
|
There's a couple of aliases in play:
1. `lib.isList` is an alias for `builtins.isList`.
2. `lib.strings.concatStringsSep` is an alias for `builtins.concatStringsSep`

* doc: add details on `mapAttrsRecursive[Cond]`
from first reading it wasn't clear that `f` also takes the current
attribute path. also the value f receives is tricky due to how the
condition is evaluated.

lib/customization: propagate function arguments in callPackagesWith

`lib/` flake: fix `lib.version`

We can just pass the error message on without creating an environment.

Returning the partially applied `zipAttrsWith fn` is the same as `sets: zipAttrsWith fn sets`.
|
|
Returning the partially applied `map getDev` is the same as `drvs: map getDev drvs`.

`lib`: Remove unneeded polyfills
|
|
makeOverridable is very careful to ensure the arguments to the
overridden function are the same as the input function. As a result,
the arguments of hello.override are exactly the same as the original
arguments of the hello function that produced the derivation.
However, callPackagesWith calls makeOverridable with a lambda that
does not propagate the arguments. The override function for a package
instantiated with callPackagesWith will not have the original
arguments.
For example:
nix-repl> lib.functionArgs hello.override
{ callPackage = false; fetchurl = false; hello = false; lib = false; nixos = false; stdenv = false; testers = false; }
nix-repl> lib.functionArgs openssl.override
{ }
By copying the arguments onto the inner lambda before passing it to
makeOverridable, we can make callPackage and callPackages behave the
same.
nix-repl> lib.functionArgs openssl.override
{ buildPackages = false; coreutils = false; cryptodev = false; enableSSL2 = true; enableSSL3 = true; fetchurl = false; lib = false; perl = false; removeReferencesTo = false; static = true; stdenv = false; withCryptodev = true; withPerl = true; }

lib.fileset: Fix tests on Darwin, more POSIX
|
|
This was found when trying to run the fileset tests on Darwin
(https://github.com/NixOS/nix/pull/9546#issuecomment-1967409445), which mysteriously fail on Darwin:
test case at lib/fileset/tests.sh:342 failed: toSource { root = "/nix/store/foobar"; fileset = ./.; } should have errored with this regex pattern:
lib.fileset.toSource: `root` \(/nix/store/foobar\) is a string-like value, but it should be a path instead.
\s*Paths in strings are not supported by `lib.fileset`, use `lib.sources` or derivations instead.
but this was the actual error:
error: lib.fileset.toSource: `root` (/nix/store/foobar) is a string-like value, but it should be a path instead.
Paths in strings are not supported by `lib.fileset`, use `lib.sources` or derivations instead.
After dissecting this, I find out that apparently \s works on Linux, but not on Darwin for some reason!
From the bash source code, it looks like <regex.h> with `REG_EXTENDED` is used for all platforms the same,
so there's nothing odd there.
It's almost impossible to know where <regex.h> comes from,
but it looks to be a POSIX thing.
So after digging through the almost impossible to find POSIX specifications
(https://pubs.opengroup.org/onlinepubs/007908799/xbd/re.html#tag_007_003_005),
I can indeed confirm that there's no mention of \s or the like!
_However_, there is a mention of `[[:blank:]]`, so we'll use that instead.

lib.meta.availableOn: add example in documentation

This way we don't have to make sure they're in sync, and we remove
a small step from the release process.
