0fa7b1b004 lib/generators.toPretty: don't evaluate derivations
With the goal of making `toPretty` suitable for rendering option
values, render derivations as `<derivation foo-1.0>` instead of
`<derivation /nix/store/…-foo-1.0.drv>`.

This is to avoid causing sudden evaluation errors for out-of-tree
projects that have options with `default = pkgs.someUnfreePackage;` and
no `defaultText`.

6110a6009f lib/modules: Add context to the "option does not exist" error
Add trace items that provide context for a failed definition that
can not be caught within the Nix language.

This also adds a test for the `tryEval` behavior of `showDefs`.

66aa02f190 lib/systems: Support FreeBSD
A tricky thing about FreeBSD is that there is no stable ABI across
versions. That means that putting in the version as part of the config
string is paramount.

We have a parsed represenation that separates name versus version to
accomplish this. We include FreeBSD versions 12 and 13 to demonstrate
how it works.

lib/types: always use <function body> instead of [function body] to indicate a function inside an option structure
The motivation is to have a single identifier for that. Useful for the
next commit where I'll try to escape option-parts correctly (options can
be any kind of strings, but unless these are Nix identifiers, they must
be quoted).

Since `<function body>` (or `<name>`/`*`) are special identifiers in
error messages and the manual, we need a unique way to mark an option
part as function call because these are not to be quoted.

lib.modules: support strings with absolute paths in disabledModules
This is particularly useful for disabling modules defined in a flake.
Example:
disabledModules = [ "${flake}/modules/mymodule.nix" ];

Previously, absolute string paths were internally prepended with `modulesPath`,
which caused the module filtering to fail.

3c4a49f506 lib/modules: Throw earlier when module function does not return attrs
`m` must always be an attrset at this point. It is basically always
evaluated. This will make it throw when any of the attrs is accessed,
rather than just `config`. We assume that this will improve the error
message in more scenarios.

lib/generators: withRecursion: don't break attr-sets with special attrs
Closes #168327

The issue reported there can be demonstrated with the following
expression:

    → nix-instantiate --eval -E "with import ./. {}; pkgs.lib.options.showDefs [ { file = \"foo\"; value = pkgs.rust.packages.stable.buildRustPackages; } ]"
    error: attempt to call something which is not a function but a string

           at /home/ma27/Projects/nixpkgs/lib/trivial.nix:442:35:

              441|   isFunction = f: builtins.isFunction f ||
              442|     (f ? __functor && isFunction (f.__functor f));
                 |                                   ^
              443|

Basically, if a `__functor` is in an attribute-set at depth-limit,
`__functor` will be set to `"<unevaluated>"`. This however breaks
`lib.isFunction` which checks for a `__functor` by invoking `__functor`
with `f` itself.

The same issue - "magic" attributes being shadowed by `withRecursion` -
also applies to others such as
`__pretty`/`__functionArgs`/`__toString`.

Since these attributes have a low-risk of causing a stack overflow
(because these are flat attr-sets or even functions), ignoring them in
`withRecursion` seems like a valid solution.

The documentation rendering for this option had to be handled a bit
specially, since it's not declared in nixos/modules like all the other
NixOS options.

As discussed in

this is the best way of adding global sections to `toINI` without
employing heuristics (i.e. checking whether something is an attrset).

12371a51e6 lib/systems: add mips64el definitions
MIPS has a large space of {architecture,abi,endianness}; this commit
adds all of them to lib/systems/platforms.nix so we can be done with
it.

Currently lib/systems/inspect.nix has a single "isMips" predicate,
which is a bit ambiguous now that we will have both mips32 and mips64
support, with the latter having two ABIs.  Let's add four new
predicates (isMips32, isMips64, isMips64n32, and isMips64n64) and
treat the now-ambiguous isMips as deprecated in favor of the
more-specific predicates.  These predicates are used mainly for
enabling/disabling target-specific workarounds, and it is extremely
rare that a platform-specific workaround is needed, and both mips32
and mips64 need exactly the same workaround.

The separate predicates (isMips64n32 and isMips64n64) for ABI
distinctions are, unfortunately, useful.  Boost's user-scheduled
threading (used by nix) does does not currently supports mips64n32,
which is a very desirable ABI on routers since they rarely have
more than 2**32 bytes of DRAM.

In addition, this also newly allows freeformTypes to be declared
multiple times and all declarations being merged together according to
normal option merging.

lib/generators: move limit detection into withRecursion
As suggested in #131205.

Now it's possible to pretty-print a value with `lib.generators` like
this:

    with lib.generators;
    toPretty { }
      (withRecursion { depthLimit = 10; } /* arbitrarily complex value */)

Also, this can be used for any other pretty-printer now if needed.

lib/generators/toPretty: add evaluation-limit
When having e.g. recursive attr-set, it cannot be printed which is
solved by Nix itself like this:

    $ nix-instantiate --eval -E 'let a.b = 1; a.c = a; in builtins.trace a 1'
    trace: { b = 1; c = <CYCLE>; }
    1

However, `generators.toPretty` tries to evaluate something until it's
done which can result in a spurious `stack-overflow`-error:

    $ nix-instantiate --eval -E 'with import <nixpkgs/lib>; generators.toPretty {  } (mkOption { type = types.str; })'
    error: stack overflow (possible infinite recursion)

Those attr-sets are in fact rather common, one example is shown above, a
`types.<type>`-declaration is such an example. By adding an optional
`depthLimit`-argument, `toPretty` will stop evaluating as soon as the
limit is reached:

    $ nix-instantiate --eval -E 'with import ./Projects/nixpkgs-update-int/lib; generators.toPretty { depthLimit = 2; } (mkOption { type = types.str; })' |xargs -0 echo -e
    "{
      _type = \"option\";
      type = {
        _type = \"option-type\";
        check = <function>;
        deprecationMessage = null;
        description = \"string\";
        emptyValue = { };
        functor = {
          binOp = <unevaluated>;
          name = <unevaluated>;
          payload = <unevaluated>;
          type = <unevaluated>;
          wrapped = <unevaluated>;
        };
        getSubModules = null;
        getSubOptions = <function>;
        merge = <function>;
        name = \"str\";
        nestedTypes = { };
        substSubModules = <function>;
        typeMerge = <function>;
      };
    }"

Optionally, it's also possible to let `toPretty` throw an error if the
limit is exceeded.

ce5e3113c3 lib/tests: Make sure the submodule type description can be evaluated
In 2d45a62899, the submodule type
description was amended with the freeformType description. This causes
all the modules passed to the submodule to be evaluated once on their
own, without any extra definitions from the config section. This means
that the specified modules need to be valid on their own, without any
undeclared options.

This commit adds a test that evaluates a submodules option description,
which would trigger the above problem for one of the tests, if it were
not fixed by this commit as well.

This is done because the next commit makes option evaluation a bit more
strict, which would also trigger this test failure, even though it's not
related to the change at all.

lib/modules: better error message if an attr-set of options is expected
I recently wrote some Nix code where I wrongly set a value to an option
which wasn't an actual option, but an attr-set of options. The mistake I
made can be demonstrated with an expression like this:

    {
      foo = { lib, pkgs, config, ... }: with lib; {
        options.foo.bar.baz = mkOption {
          type = types.str;
        };
        config.foo.bar = 23;
      };
    }

While it wasn't too hard to find the cause of the mistake for me, it was
necessary to have some practice in reading stack traces from the module
system since the eval-error I got was not very helpful:

    error: --- TypeError --------------------------------------------------------- nix-build
    at: (323:25) in file: /nix/store/3nm31brdz95pj8gch5gms6xwqh0xx55c-source/lib/modules.nix

       322|         foldl' (acc: module:
       323|                 acc // (mapAttrs (n: v:
          |                         ^
       324|                                    (acc.${n} or []) ++ f module v

    value is an integer while a set was expected
    (use '--show-trace' to show detailed location information)

I figured that such an error can be fairly confusing for someone who's
new to NixOS, so I decided to catch this case in th `byName` function in
`lib/modules.nix` by checking if the value to map through is an actual
attr-set. If not, a different error will be thrown.

72b3badb61 lib.systems: add powerpc64-linux
PPC64 supports two ABIs: ELF v1 and v2.

ELFv1 is historically what GCC and most packages expect, but this is
changing because musl outright does not work with ELFv1. So any distro
which uses musl must use ELFv2. Many other platforms are moving to ELFv2
too, such as FreeBSD (as of v13) and Gentoo (as of late 2020).

Since we use musl extensively, let's default to ELFv2.

Nix gives us the power to specify this declaratively for the entire
system, so ELFv1 is not dropped entirely. It can be specified explicitly
in the target config, e.g. "powerpc64-unknown-linux-elfv1". Otherwise the
default is "powerpc64-unknown-linux-elfv2". For musl,
"powerpc64-unknown-linux-musl" must use elfv2 internally to function.

lib/modules: Introduce _module.checks.*.check
Previously the .enable option was used to encode the condition as well,
which lead to some oddness:
- In order to encode an assertion, one had to invert it
- To disable a check, one had to mkForce it

By introducing a separate .check option this is solved because:
- It can be used to encode assertions
- Disabling is done separately with .enable option, whose default can be
  overridden without a mkForce

582354d3b6 lib/cli: encodeGNUCommandLine -> toGNUCommandLineShell
The semantic difference between `encode` and `to` is not apparent.
Users are likely to confuse both functions (which leads to unexpected
error messages about the wrong types). Like in `generators.nix`, all
functions should be prefixed by `to`.

Furthermore, converting to a string depends on the target context. In
this case, it’s a POSIX shell, so we should name it that (compare
`escapeShellArg` in `strings.nix`).

We can later add versions that escape for embedding in e.g. python
scripts or similar.

183a99734f Add pkgs.lib.renderOptions
This adds a new utility to intelligently convert Nix records to
command line options to reduce boilerplate for simple use cases and to
also reduce the likelihood of malformed command lines

8252861507 lib/trivial: add pipe function
`pipe` is a useful operator for creating pipelines of functions.

It works around the usual problem of e.g. string operations becoming
deeply nested functions.

In principle, there are four different ways this function could be
written:

pipe val [ f1 .. fn ]
pipe val [ fn .. f1 ]
compose [ f1 .. fn ] val
compose [ fn .. f1 ] val

The third and fourth form mirror composition of functions, they would
be the same as e.g. `(f1 << f2 << f3 .. << fn) val`.
However, it is not clear which direction the list should have (as one
can see in the second form, which is the most absurd.

In order not to confuse users, we decide for the most “intuitive”
form, which mirrors the way unix pipes work (thus the name `pipe`).
The flow of data goes from left to right.

d059185bad Revert "Revert "systems/doubles.nix: add Apple doubles""
This reverts commit ce2f74df2c.

Doubles are treated as -darwin here, to provide some consistency.
There is some ambiguity between “x86_64-darwin” and “i686-darwin”
which could refer to binaries linked between iOS simulator or real
macOS binaries. useiOSPrebuilt can be used to determine which to use,
however.

0fef9f89e4 systems: fix lib-tests
These were broken by the added system doubles. This just adds those to
the lib-tests.

81fa1e392b lib/modules: Change mkAliasOptionModule to use the priority for the alias.
This commit changes the `mkAliasOptionModule` function to make sure that
the priority for the aliased option is propagated to the non-aliased
option.

This also affects the `mkRenamedOptionModule` function in a similar
fashion.

This also removes the `mkAliasOptionModuleWithPriority` function, since
its functionality is now subsumed by `mkAliasOptionModule`.

This change was recommended by @nbp:
