 Package version upgrades usually allow for simpler commit messages, including attribute name, old and new version, as well as a reference to the relevant release notes/changelog. Every once in a while a package upgrade requires more extensive changes, and that subsequently warrants a more verbose message.
 
-Pull requests should not be squash merged in order to keep complete commit messages and GPG signatures intact and must not be when the change doesn't make sense as a single commit.
-This means that, when addressing review comments in order to keep the pull request in an always mergeable status, you will sometimes need to rewrite your branch's history and then force-push it with `git push --force-with-lease`.
-Useful git commands that can help a lot with this are `git commit --patch --amend` and `git rebase --interactive`.

-# pkgs.mkBinaryCache {#sec-pkgs-binary-cache}
-
-`pkgs.mkBinaryCache` is a function for creating Nix flat-file binary caches. Such a cache exists as a directory on disk, and can be used as a Nix substituter by passing `--substituter file:///path/to/cache` to Nix commands.
-
-Nix packages are most commonly shared between machines using [HTTP, SSH, or S3](https://nixos.org/manual/nix/stable/package-management/sharing-packages.html), but a flat-file binary cache can still be useful in some situations. For example, you can copy it directly to another machine, or make it available on a network file system. It can also be a convenient way to make some Nix packages available inside a container via bind-mounting.
-
-Note that this function is meant for advanced use-cases. The more idiomatic way to work with flat-file binary caches is via the [nix-copy-closure](https://nixos.org/manual/nix/stable/command-ref/nix-copy-closure.html) command. You may also want to consider [dockerTools](#sec-pkgs-dockerTools) for your containerization needs.
-
-## Example
-
-The following derivation will construct a flat-file binary cache containing the closure of `hello`.
-
-```nix
-mkBinaryCache {
-  rootPaths = [hello];
-}
-```
-
-- `rootPaths` specifies a list of root derivations. The transitive closure of these derivations' outputs will be copied into the cache.
-
-Here's an example of building and using the cache.
-
-Build the cache on one machine, `host1`:
-
-```shellSession
-nix-build -E 'with import <nixpkgs> {}; mkBinaryCache { rootPaths = [hello]; }'
-```
-
-```shellSession
-/nix/store/cc0562q828rnjqjyfj23d5q162gb424g-binary-cache
-```
-
-Copy the resulting directory to the other machine, `host2`:
-
-```shellSession
-scp result host2:/tmp/hello-cache
-```
-
-Substitute the derivation using the flat-file binary cache on the other machine, `host2`:
-```shellSession
-nix-build -A hello '<nixpkgs>' \
-  --option require-sigs false \
-  --option trusted-substituters file:///tmp/hello-cache \
-  --option substituters file:///tmp/hello-cache

-## buildNixShellImage {#ssec-pkgs-dockerTools-buildNixShellImage}
-
-Create a Docker image that sets up an environment similar to that of running `nix-shell` on a derivation.
-When run in Docker, this environment somewhat resembles the Nix sandbox typically used by `nix-build`, with a major difference being that access to the internet is allowed.
-It additionally also behaves like an interactive `nix-shell`, running things like `shellHook` and setting an interactive prompt.
-If the derivation is fully buildable (i.e. `nix-build` can be used on it), running `buildDerivation` inside such a Docker image will build the derivation, with all its outputs being available in the correct `/nix/store` paths, pointed to by the respective environment variables like `$out`, etc.
-
-::: {.warning}
-The behavior doesn't match `nix-shell` or `nix-build` exactly and this function is known not to work correctly for e.g. fixed-output derivations, content-addressed derivations, impure derivations and other special types of derivations.
-:::
-
-### Arguments
-
-`drv`
-
-: The derivation on which to base the Docker image.
-
-    Adding packages to the Docker image is possible by e.g. extending the list of `nativeBuildInputs` of this derivation like
-
-    ```nix
-    buildNixShellImage {
-      drv = someDrv.overrideAttrs (old: {
-        nativeBuildInputs = old.nativeBuildInputs or [] ++ [
-          somethingExtra
-        ];
-      });
-      # ...
-    }
-    ```
-
-    Similarly, you can extend the image initialization script by extending `shellHook`
-
-`name` _optional_
-
-: The name of the resulting image.
-
-    *Default:* `drv.name + "-env"`
-
-`tag` _optional_
-
-: Tag of the generated image.
-
-    *Default:* the resulting image derivation output path's hash
-
-`uid`/`gid` _optional_
-
-: The user/group ID to run the container as. This is like a `nixbld` build user.
-
-    *Default:* 1000/1000
-
-`homeDirectory` _optional_
-
-: The home directory of the user the container is running as
-
-    *Default:* `/build`
-
-`shell` _optional_
-
-: The path to the `bash` binary to use as the shell. This shell is started when running the image.
-
-    *Default:* `pkgs.bashInteractive + "/bin/bash"`
-
-`command` _optional_
-
-: Run this command in the environment of the derivation, in an interactive shell. See the `--command` option in the [`nix-shell` documentation](https://nixos.org/manual/nix/stable/command-ref/nix-shell.html?highlight=nix-shell#options).
-
-    *Default:* (none)
-
-`run` _optional_
-
-: Same as `command`, but runs the command in a non-interactive shell instead. See the `--run` option in the [`nix-shell` documentation](https://nixos.org/manual/nix/stable/command-ref/nix-shell.html?highlight=nix-shell#options).
-
-    *Default:* (none)
-
-### Example
-
-The following shows how to build the `pkgs.hello` package inside a Docker container built with `buildNixShellImage`.
-
-```nix
-with import <nixpkgs> {};
-dockerTools.buildNixShellImage {
-  drv = hello;
-}
-```
-
-Build the derivation:
-
-```console
-nix-build hello.nix
-```
-
-    these 8 derivations will be built:

-# `<nixpkgs/nixos/lib/make-disk-image.nix>` {#sec-make-disk-image}
-
-`<nixpkgs/nixos/lib/make-disk-image.nix>` is a function to create _disk images_ in multiple formats: raw, QCOW2 (QEMU), QCOW2-Compressed (compressed version), VDI (VirtualBox), VPC (VirtualPC).
-
-This function can create images in two ways:
-
-- using `cptofs` without any virtual machine to create a Nix store disk image,
-- using a virtual machine to create a full NixOS installation.
-
-When testing early-boot or lifecycle parts of NixOS such as a bootloader or multiple generations, it is necessary to opt for a full NixOS system installation.
-Whereas for many web servers, applications, it is possible to work with a Nix store only disk image and is faster to build.
-
-NixOS tests also use this function when preparing the VM. The `cptofs` method is used when `virtualisation.useBootLoader` is false (the default). Otherwise the second method is used.
-
-## Features
-
-For reference, read the function signature source code for documentation on arguments: <https://github.com/NixOS/nixpkgs/blob/master/nixos/lib/make-disk-image.nix>.
-Features are separated in various sections depending on if you opt for a Nix-store only image or a full NixOS image.
-
-### Common
-
-- arbitrary NixOS configuration
-- automatic or bound disk size: `diskSize` parameter, `additionalSpace` can be set when `diskSize` is `auto` to add a constant of disk space
-- multiple partition table layouts: EFI, legacy, legacy + GPT, hybrid, none through `partitionTableType` parameter
-- OVMF or EFI firmwares and variables templates can be customized
-- root filesystem `fsType` can be customized to whatever `mkfs.${fsType}` exist during operations
-- root filesystem label can be customized, defaults to `nix-store` if it's a Nix store image, otherwise `nixpkgs/nixos`
-- arbitrary code can be executed after disk image was produced with `postVM`
-- the current nixpkgs can be realized as a channel in the disk image, which will change the hash of the image when the sources are updated
-- additional store paths can be provided through `additionalPaths`
-
-### Full NixOS image
-
-- arbitrary contents with permissions can be placed in the target filesystem using `contents`
-- a `/etc/nixpkgs/nixos/configuration.nix` can be provided through `configFile`
-- bootloaders are supported
-- EFI variables can be mutated during image production and the result is exposed in `$out`
-- boot partition size when partition table is `efi` or `hybrid`
-
-### On bit-to-bit reproducibility
-
-Images are **NOT** deterministic, please do not hesitate to try to fix this, source of determinisms are (not exhaustive) :
-
-- bootloader installation have timestamps
-- SQLite Nix store database contain registration times
-- `/etc/shadow` is in a non-deterministic order
-
-A `deterministic` flag is available for best efforts determinism.
-
-## Usage
-
-To produce a Nix-store only image:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = {};
-    additionalPaths = [ ];
-    format = "qcow2";
-    onlyNixStore = true;
-    partitionTableType = "none";
-    installBootLoader = false;
-    touchEFIVars = false;
-    diskSize = "auto";
-    additionalSpace = "0M"; # Defaults to 512M.
-    copyChannel = false;
-  }
-```
-
-Some arguments can be left out, they are shown explicitly for the sake of the example.
-
-Building this derivation will provide a QCOW2 disk image containing only the Nix store and its registration information.
-
-To produce a NixOS installation image disk with UEFI and bootloader installed:
-```nix
-let
-  pkgs = import <nixpkgs> {};
-  lib = pkgs.lib;
-  make-disk-image = import <nixpkgs/nixos/lib/make-disk-image.nix>;
-  evalConfig = import <nixpkgs/nixos/lib/eval-config.nix>;
-in
-  make-disk-image {
-    inherit pkgs lib;
-    config = evalConfig {
-      modules = [
-        {
-          fileSystems."/" = { device = "/dev/vda"; fsType = "ext4"; autoFormat = true; };
-          boot.grub.device = "/dev/vda";
-        }
-      ];
-    };
-    format = "qcow2";
-    onlyNixStore = false;
-    partitionTableType = "legacy+gpt";

 When fetching from GitHub, commits must always be referenced by their full commit hash. This is because GitHub shares commit hashes among all forks and returns `404 Not Found` when a short commit hash is ambiguous. It already happens for some short, 6-character commit hashes in `nixpkgs`.
 It is a practical vector for a denial-of-service attack by pushing large amounts of auto generated commits into forks and was already [demonstrated against GitHub Actions Beta](https://blog.teddykatz.com/2019/11/12/github-actions-dos.html).

-# Cue (Cuelang) {#cuelang}
-
-[Cuelang](https://cuelang.org/) is a language to:
-
-- describe schemas and validate backward-compatibility
-- generate code and schemas in various formats (e.g. JSON Schema, OpenAPI)
-- do configuration akin to [Dhall Lang](https://dhall-lang.org/)
-- perform data validation
-
-## Cuelang schema quick start
-
-Cuelang schemas are similar to JSON, here is a quick cheatsheet:
-
-- Default types includes: `null`, `string`, `bool`, `bytes`, `number`, `int`, `float`, lists as `[...T]` where `T` is a type.
-- All structures, defined by: `myStructName: { <fields> }` are **open** -- they accept fields which are not specified.
-- Closed structures can be built by doing `myStructName: close({ <fields> })` -- they are strict in what they accept.
-- `#X` are **definitions**, referenced definitions are **recursively closed**, i.e. all its children structures are **closed**.
-- `&` operator is the [unification operator](https://cuelang.org/docs/references/spec/#unification) (similar to a type-level merging operator), `|` is the [disjunction operator](https://cuelang.org/docs/references/spec/#disjunction) (similar to a type-level union operator).
-- Values **are** types, i.e. `myStruct: { a: 3 }` is a valid type definition that only allows `3` as value.
-
-- Read <https://cuelang.org/docs/concepts/logic/> to learn more about the semantics.
-- Read <https://cuelang.org/docs/references/spec/> to learn about the language specification.
-
-## `writeCueValidator`
-
-Nixpkgs provides a `pkgs.writeCueValidator` helper, which will write a validation script based on the provided Cuelang schema.
-
-Here is an example:
-```
-pkgs.writeCueValidator
-  (pkgs.writeText "schema.cue" ''
-    #Def1: {
-      field1: string
-    }
-  '')
-  { document = "#Def1"; }
-```
-
-- The first parameter is the Cue schema file.
-- The second parameter is an options parameter, currently, only: `document` can be passed.
-
-`document` : match your input data against this fragment of structure or definition, e.g. you may use the same schema file but different documents based on the data you are validating.
-
-Another example, given the following `validator.nix` :
-```
-{ pkgs ? import <nixpkgs> {} }:
-let
-  genericValidator = version:
-  pkgs.writeCueValidator
-    (pkgs.writeText "schema.cue" ''
-      #Version1: {
-        field1: string
-      }
-      #Version2: #Version1 & {
-        field1: "unused"
-      }''
-    )
-    { document = "#Version${toString version}"; };
-in
-{
-  validateV1 = genericValidator 1;
-  validateV2 = genericValidator 2;
-}
-```
-
-The result is a script that will validate the file you pass as the first argument against the schema you provided `writeCueValidator`.
-
-It can be any format that `cue vet` supports, i.e. YAML or JSON for example.
-
-Here is an example, named `example.json`, given the following JSON:
-```
-{ "field1": "abc" }
-```
-
-You can run the result script (named `validate`) as the following:
-
-```console
-$ nix-build validator.nix
-$ ./result example.json
-$ ./result-2 example.json
-field1: conflicting values "unused" and "abc":
-    ./example.json:1:13
-    ../../../../../../nix/store/v64dzx3vr3glpk0cq4hzmh450lrwh6sg-schema.cue:5:11
-$ sed -i 's/"abc"/3/' example.json

-    ./example.json:1:13
-    ../../../../../../nix/store/v64dzx3vr3glpk0cq4hzmh450lrwh6sg-schema.cue:5:11
-```
-
-**Known limitations**
-
-* The script will enforce **concrete** values and will not accept lossy transformations (strictness). You can add these options if you need them.

-  `vendorHash` can also be set to `null`.
-  In that case, rather than fetching the dependencies and vendoring them, the dependencies vendored in the source repo will be used.

+- `vendorHash`: is the hash of the output of the intermediate fetcher derivation. `vendorHash` can also take `null` as an input. When `null` is used as a value, rather than fetching the dependencies and vendoring them, we use the vendoring included within the source repo. If you'd like to not have to update this field on dependency changes, run `go mod vendor` in your source repo and set `vendorHash = null;`
 - `proxyVendor`: Fetches (go mod download) and proxies the vendor directory. This is useful if your code depends on c code and go mod tidy does not include the needed sources to build or if any dependency has case-insensitive conflicts which will produce platform dependant `vendorHash` checksums.

-*pkg-config* is a unified interface for declaring and querying built C/C++ libraries.

-Nixpkgs provides a couple of facilities for working with this tool.
-
-## Writing packages providing pkg-config modules
-
-Packages should set `meta.pkgConfigModules` with the list of package config modules they provide.
-They should also use `testers.testMetaPkgConfig` to check that the final built package matches that list.
-Additionally, the [`validatePkgConfig` setup hook](https://nixos.org/manual/nixpkgs/stable/#validatepkgconfig), will do extra checks on to-be-installed pkg-config modules.
-
-A good example of all these things is zlib:

-## Accessing packages via pkg-config module name
-
-### Within Nixpkgs
-
-A [setup hook](#setup-hook-pkg-config) is bundled in the `pkg-config` package to bring a derivation's declared build inputs into the environment.
-This will populate environment variables like `PKG_CONFIG_PATH`, `PKG_CONFIG_PATH_FOR_BUILD`, and `PKG_CONFIG_PATH_HOST` based on:
-
- - how `pkg-config` itself is depended upon
-
- - how other dependencies are depended upon
-
-For more details see the section on [specifying dependencies in general](#ssec-stdenv-dependencies).
-
-Normal pkg-config commands to look up dependencies by name will then work with those environment variables defined by the hook.
-
-### Externally
-
-The `defaultPkgConfigPackages` package set is a set of aliases, named after the modules they provide.
-This is meant to be used by language-to-nix integrations.
-Hand-written packages should use the normal Nixpkgs attribute name instead.

-The major caveat with Qt applications is that Qt uses a plugin system to load additional modules at runtime,

+## `buildRustCrate`: Compiling Rust crates using Nix instead of Cargo {#compiling-rust-crates-using-nix-instead-of-cargo}
+
+### Simple operation {#simple-operation}
+
+When run, `cargo build` produces a file called `Cargo.lock`,
+containing pinned versions of all dependencies. Nixpkgs contains a
+tool called `carnix` (`nix-env -iA nixos.carnix`), which can be used
+to turn a `Cargo.lock` into a Nix expression.
+
+That Nix expression calls `rustc` directly (hence bypassing Cargo),
+and can be used to compile a crate and all its dependencies. Here is
+an example for a minimal `hello` crate:
+
+```ShellSession
+$ cargo new hello
+$ cd hello
+$ cargo build
+     Compiling hello v0.1.0 (file:///tmp/hello)
+     Finished dev [unoptimized + debuginfo] target(s) in 0.20 secs
+$ carnix -o hello.nix --src ./. Cargo.lock --standalone
+$ nix-build hello.nix -A hello_0_1_0
+```
+
+Now, the file produced by the call to `carnix`, called `hello.nix`, looks like:
+
+```nix
+# Generated by carnix 0.6.5: carnix -o hello.nix --src ./. Cargo.lock --standalone
+{ stdenv, buildRustCrate, fetchgit }:
+let kernel = stdenv.buildPlatform.parsed.kernel.name;
+    # ... (content skipped)
+in
+rec {
+  hello = f: hello_0_1_0 { features = hello_0_1_0_features { hello_0_1_0 = f; }; };
+  hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
+    crateName = "hello";
+    version = "0.1.0";
+    authors = [ "pe@pijul.org <pe@pijul.org>" ];
+    src = ./.;
+    inherit dependencies buildDependencies features;
+  };
+  hello_0_1_0 = { features?(hello_0_1_0_features {}) }: hello_0_1_0_ {};
+  hello_0_1_0_features = f: updateFeatures f (rec {
+        hello_0_1_0.default = (f.hello_0_1_0.default or true);
+    }) [ ];
+}
+```
+
+In particular, note that the argument given as `--src` is copied
+verbatim to the source. If we look at a more complicated
+dependencies, for instance by adding a single line `libc="*"` to our
+`Cargo.toml`, we first need to run `cargo build` to update the
+`Cargo.lock`. Then, `carnix` needs to be run again, and produces the
+following nix file:
+
+```nix
+# Generated by carnix 0.6.5: carnix -o hello.nix --src ./. Cargo.lock --standalone
+{ stdenv, buildRustCrate, fetchgit }:
+let kernel = stdenv.buildPlatform.parsed.kernel.name;
+    # ... (content skipped)
+in
+rec {
+  hello = f: hello_0_1_0 { features = hello_0_1_0_features { hello_0_1_0 = f; }; };
+  hello_0_1_0_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
+    crateName = "hello";
+    version = "0.1.0";
+    authors = [ "pe@pijul.org <pe@pijul.org>" ];
+    src = ./.;
+    inherit dependencies buildDependencies features;
+  };
+  libc_0_2_36_ = { dependencies?[], buildDependencies?[], features?[] }: buildRustCrate {
+    crateName = "libc";
+    version = "0.2.36";
+    authors = [ "The Rust Project Developers" ];
+    sha256 = "01633h4yfqm0s302fm0dlba469bx8y6cs4nqc8bqrmjqxfxn515l";
+    inherit dependencies buildDependencies features;
+  };
+  hello_0_1_0 = { features?(hello_0_1_0_features {}) }: hello_0_1_0_ {
+    dependencies = mapFeatures features ([ libc_0_2_36 ]);
+  };
+  hello_0_1_0_features = f: updateFeatures f (rec {
+    hello_0_1_0.default = (f.hello_0_1_0.default or true);
+    libc_0_2_36.default = true;
+  }) [ libc_0_2_36_features ];
+  libc_0_2_36 = { features?(libc_0_2_36_features {}) }: libc_0_2_36_ {
+    features = mkFeatures (features.libc_0_2_36 or {});
+  };
+  libc_0_2_36_features = f: updateFeatures f (rec {
+    libc_0_2_36.default = (f.libc_0_2_36.default or true);
+    libc_0_2_36.use_std =
+      (f.libc_0_2_36.use_std or false) ||
+      (f.libc_0_2_36.default or false) ||
+      (libc_0_2_36.default or false);
+  }) [];
+}
+```
+
+Here, the `libc` crate has no `src` attribute, so `buildRustCrate`
+will fetch it from [crates.io](https://crates.io). A `sha256`
+attribute is still needed for Nix purity.
+
+### Handling external dependencies {#handling-external-dependencies}
+
+Some crates require external libraries. For crates from
+[crates.io](https://crates.io), such libraries can be specified in
+`defaultCrateOverrides` package in nixpkgs itself.
+
+Starting from that file, one can add more overrides, to add features
+or build inputs by overriding the hello crate in a separate file.
+
+```nix
+with import <nixpkgs> {};
+((import ./hello.nix).hello {}).override {
+  crateOverrides = defaultCrateOverrides // {
+    hello = attrs: { buildInputs = [ openssl ]; };
+  };
+}
+```
+
+Here, `crateOverrides` is expected to be a attribute set, where the
+key is the crate name without version number and the value a function.
+The function gets all attributes passed to `buildRustCrate` as first
+argument and returns a set that contains all attribute that should be
+overwritten.
+
+For more complicated cases, such as when parts of the crate's
+derivation depend on the crate's version, the `attrs` argument of
+the override above can be read, as in the following example, which
+patches the derivation:
+
+```nix
+with import <nixpkgs> {};
+((import ./hello.nix).hello {}).override {
+  crateOverrides = defaultCrateOverrides // {
+    hello = attrs: lib.optionalAttrs (lib.versionAtLeast attrs.version "1.0")  {
+      postPatch = ''
+        substituteInPlace lib/zoneinfo.rs \
+          --replace "/usr/share/zoneinfo" "${tzdata}/share/zoneinfo"
+      '';
+    };
+  };
+}
+```
+
+Another situation is when we want to override a nested
+dependency. This actually works in the exact same way, since the
+`crateOverrides` parameter is forwarded to the crate's
+dependencies. For instance, to override the build inputs for crate
+`libc` in the example above, where `libc` is a dependency of the main
+crate, we could do:
+
+```nix
+with import <nixpkgs> {};
+((import hello.nix).hello {}).override {
+  crateOverrides = defaultCrateOverrides // {
+    libc = attrs: { buildInputs = []; };
+  };
+}
+```
+
+### Options and phases configuration {#options-and-phases-configuration}
+
+Actually, the overrides introduced in the previous section are more
+general. A number of other parameters can be overridden:
+
+- The version of `rustc` used to compile the crate:
+
+  ```nix
+  (hello {}).override { rust = pkgs.rust; };
+  ```
+
+- Whether to build in release mode or debug mode (release mode by
+  default):
+
+  ```nix
+  (hello {}).override { release = false; };
+  ```
+
+- Whether to print the commands sent to `rustc` when building
+  (equivalent to `--verbose` in cargo:
+
+  ```nix
+  (hello {}).override { verbose = false; };
+  ```
+
+- Extra arguments to be passed to `rustc`:

+  ```nix

+
+- Phases, just like in any other derivation, can be specified using
+  the following attributes: `preUnpack`, `postUnpack`, `prePatch`,
+  `patches`, `postPatch`, `preConfigure` (in the case of a Rust crate,
+  this is run before calling the "build" script), `postConfigure`
+  (after the "build" script),`preBuild`, `postBuild`, `preInstall` and
+  `postInstall`. As an example, here is how to create a new module
+  before running the build script:
+
+  ```nix
+  (hello {}).override {
+    preConfigure = ''
+       echo "pub const PATH=\"${hi.out}\";" >> src/path.rs"
+    '';
+  };
+  ```
+
+### Features {#features}
+
+One can also supply features switches. For example, if we want to
+compile `diesel_cli` only with the `postgres` feature, and no default
+features, we would write:
+
+```nix
+(callPackage ./diesel.nix {}).diesel {
+  default = false;
+  postgres = true;
+}
+```
+
+Where `diesel.nix` is the file generated by Carnix, as explained above.

-# Swift {#swift}
-
-The Swift compiler is provided by the `swift` package:
-
-```sh
-# Compile and link a simple executable.
-nix-shell -p swift --run 'swiftc -' <<< 'print("Hello world!")'
-# Run it!
-./main
-```
-
-The `swift` package also provides the `swift` command, with some caveats:
-
-- Swift Package Manager (SwiftPM) is packaged separately as `swiftpm`. If you
-  need functionality like `swift build`, `swift run`, `swift test`, you must
-  also add the `swiftpm` package to your closure.
-- On Darwin, the `swift repl` command requires an Xcode installation. This is
-  because it uses the system LLDB debugserver, which has special entitlements.
-
-## Module search paths {#ssec-swift-module-search-paths}
-
-Like other toolchains in Nixpkgs, the Swift compiler executables are wrapped
-to help Swift find your application's dependencies in the Nix store. These
-wrappers scan the `buildInputs` of your package derivation for specific
-directories where Swift modules are placed by convention, and automatically
-add those directories to the Swift compiler search paths.
-
-Swift follows different conventions depending on the platform. The wrappers
-look for the following directories:
-
-- On Darwin platforms: `lib/swift/macosx`
-  (If not targeting macOS, replace `macosx` with the Xcode platform name.)
-- On other platforms: `lib/swift/linux/x86_64`
-  (Where `linux` and `x86_64` are from lowercase `uname -sm`.)
-- For convenience, Nixpkgs also adds simply `lib/swift` to the search path.
-  This can save a bit of work packaging Swift modules, because many Nix builds
-  will produce output for just one target any way.
-
-## Core libraries {#ssec-swift-core-libraries}
-
-In addition to the standard library, the Swift toolchain contains some
-additional 'core libraries' that, on Apple platforms, are normally distributed
-as part of the OS or Xcode. These are packaged separately in Nixpkgs, and can
-be found (for use in `buildInputs`) as:
-
-- `swiftPackages.Dispatch`
-- `swiftPackages.Foundation`
-- `swiftPackages.XCTest`
-
-## Packaging with SwiftPM {#ssec-swift-packaging-with-swiftpm}
-
-Nixpkgs includes a small helper `swiftpm2nix` that can fetch your SwiftPM
-dependencies for you, when you need to write a Nix expression to package your
-application.
-
-The first step is to run the generator:
-
-```sh
-cd /path/to/my/project
-# Enter a Nix shell with the required tools.
-nix-shell -p swift swiftpm swiftpm2nix
-# First, make sure the workspace is up-to-date.
-swift package resolve
-# Now generate the Nix code.
-swiftpm2nix
-```
-
-This produces some files in a directory `nix`, which will be part of your Nix
-expression. The next step is to write that expression:
-
-```nix
-{ stdenv, swift, swiftpm, swiftpm2nix, fetchFromGitHub }:
-
-let
-  # Pass the generated files to the helper.
-  generated = swiftpm2nix.helpers ./nix;
-in
-
-stdenv.mkDerivation rec {
-  pname = "myproject";
-  version = "0.0.0";
-
-  src = fetchFromGitHub {
-    owner = "nixos";
-    repo = pname;
-    rev = version;
-    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
-  };
-
-  # Including SwiftPM as a nativeBuildInput provides a buildPhase for you.
-  # This by default performs a release build using SwiftPM, essentially:
-  #   swift build -c release
-  nativeBuildInputs = [ swift swiftpm ];
-
-  # The helper provides a configure snippet that will prepare all dependencies
-  # in the correct place, where SwiftPM expects them.
-  configurePhase = generated.configure;
-
-  installPhase = ''
-    # This is a special function that invokes swiftpm to find the location
-    # of the binaries it produced.
-    binPath="$(swiftpmBinPath)"
-    # Now perform any installation steps.
-    mkdir -p $out/bin
-    cp $binPath/myproject $out/bin/
-  '';
-}
-```
-
-### Custom build flags {#ssec-swiftpm-custom-build-flags}
-
-If you'd like to build a different configuration than `release`:
-
-```nix
-swiftpmBuildConfig = "debug";
-```
-
-It is also possible to provide additional flags to `swift build`:
-
-```nix
-swiftpmFlags = [ "--disable-dead-strip" ];
-```
-
-The default `buildPhase` already passes `-j` for parallel building.
-
-If these two customization options are insufficient, simply provide your own
-`buildPhase` that invokes `swift build`.
-
-### Running tests {#ssec-swiftpm-running-tests}
-
-Including `swiftpm` in your `nativeBuildInputs` also provides a default
-`checkPhase`, but it must be enabled with:
-
-```nix
-doCheck = true;
-```
-
-This essentially runs: `swift test -c release`
-
-### Patching dependencies {#ssec-swiftpm-patching-dependencies}
-
-In some cases, it may be necessary to patch a SwiftPM dependency. SwiftPM
-dependencies are located in `.build/checkouts`, but the `swiftpm2nix` helper
-provides these as symlinks to read-only `/nix/store` paths. In order to patch
-them, we need to make them writable.
-
-A special function `swiftpmMakeMutable` is available to replace the symlink
-with a writable copy:
-
-```
-configurePhase = generated.configure ++ ''
-  # Replace the dependency symlink with a writable copy.
-  swiftpmMakeMutable swift-crypto
-  # Now apply a patch.
-  patch -p1 -d .build/checkouts/swift-crypto -i ${./some-fix.patch}
-'';
-```
-
-## Considerations for custom build tools {#ssec-swift-considerations-for-custom-build-tools}
-
-### Linking the standard library {#ssec-swift-linking-the-standard-library}
-
-The `swift` package has a separate `lib` output containing just the Swift
-standard library, to prevent Swift applications needing a dependency on the
-full Swift compiler at run-time. Linking with the Nixpkgs Swift toolchain
-already ensures binaries correctly reference the `lib` output.
-
-Sometimes, Swift is used only to compile part of a mixed codebase, and the
-link step is manual. Custom build tools often locate the standard library
-relative to the `swift` compiler executable, and while the result will work,
-when this path ends up in the binary, it will have the Swift compiler as an
-unintended dependency.
-
-In this case, you should investigate how your build process discovers the
-standard library, and override the path. The correct path will be something
-like: `"${swift.swift.lib}/${swift.swiftModuleSubdir}"`

-Add dependencies to `nativeBuildInputs` if they are executed during the build:

-- [setup hooks](#ssec-setup-hooks), for example [`makeWrapper`](#fun-makeWrapper)
-- interpreters needed by [`patchShebangs`](#patch-shebangs.sh) for build scripts (with the `--build` flag), which can be the case for e.g. `perl`
-
-Add dependencies to `buildInputs` if they will end up copied or linked into the final output or otherwise used at runtime:

-But it also executes the `wayland-scanner` program as part of the build to generate code, so `wayland` should also be added to `nativeBuildInputs`.
-:::

-Dependencies needed only to run tests are similarly classified between native (executed during build) and non-native (executed at runtime):
-- `nativeCheckInputs` for test tools needed on `$PATH` (such as `ctest`) and [setup hooks](#ssec-setup-hooks) (for example [`pytestCheckHook`](#python))
-- `checkInputs` for libraries linked into test executables (for example the `qcheck` OCaml package)

-- `pkg-config` is a build tool which the configure script of `solo5` expects to be on `$PATH` during the build:
-  therefore, it must be added to `nativeBuildInputs`.
-- `libseccomp` is a library linked into `$out/bin/solo5-elftool`.
-  As it is used at runtime, it must be added to `buildInputs`.
-- Tests need `qemu` and `getopt` (from `util-linux`) on `$PATH`, these must be added to `nativeCheckInputs`.
-- Some dependencies are injected directly in the shell code of phases: `syslinux`, `dosfstools`, `mtools`, and `parted`.

-### Reference {#ssec-stdenv-dependencies-reference}

 As described in the Nix manual, almost any `*.drv` store path in a derivation’s attribute set will induce a dependency on that derivation. `mkDerivation`, however, takes a few attributes intended to include all the dependencies of a package. This is done both for structure and consistency, but also so that certain other setup can take place. For example, certain dependencies need their bin directories added to the `PATH`. That is built-in, but other setup is done via a pluggable mechanism that works in conjunction with these dependency attributes. See [](#ssec-setup-hooks) for details.
 
 Dependencies can be broken down along three axes: their host and target platforms relative to the new derivation’s, and whether they are propagated. The platform distinctions are motivated by cross compilation; see [](#chap-cross) for exactly what each platform means. [^footnote-stdenv-ignored-build-platform] But even if one is not cross compiling, the platforms imply whether or not the dependency is needed at run-time or build-time, a concept that makes perfect sense outside of cross compilation. By default, the run-time/build-time distinction is just a hint for mental clarity, but with `strictDeps` set it is mostly enforced even in the native case.

 Overall, the unifying theme here is that propagation shouldn’t be introducing transitive dependencies involving platforms the depending package is unaware of. \[One can imagine the dependending package asking for dependencies with the platforms it knows about; other platforms it doesn’t know how to ask for. The platform description in that scenario is a kind of unforagable capability.\] The offset bounds checking and definition of `mapOffset` together ensure that this is the case. Discovering a new offset is discovering a new platform, and since those platforms weren’t in the derivation “spec” of the needing package, they cannot be relevant. From a capability perspective, we can imagine that the host and target platforms of a package are the capabilities a package requires, and the depending package must provide the capability to the dependency.

 A list of dependencies whose host and target platforms match the new derivation’s host platform. In practice, this would usually be tools used by compilers for macros or a metaprogramming system, or libraries used by the macros or metaprogramming code itself.

 These are often programs and libraries used by the new derivation at *run*-time, but that isn’t always the case. For example, the machine code in a statically-linked library is only used at run-time, but the derivation containing the library is only needed at build-time. Even in the dynamic case, the library may also be needed at build-time to appease the linker.

 Nix itself considers a build-time dependency as merely something that should previously be built and accessible at build time—packages themselves are on their own to perform any additional setup. In most cases, that is fine, and the downstream derivation can deal with its own dependencies. But for a few common tasks, that would result in almost every package doing the same sort of setup work—depending not on the package itself, but entirely on which dependencies were used.
