Building this package twice does not produce the bit-by-bit identical result each time, making it harder to detect CI breaches. You can read more about this at https://reproducible-builds.org/ .
<!--
Hello dear reporter,
Fixing bit-by-bit reproducibility also has additional advantages, such as avoiding hard-to-reproduce bugs, making content-addressed storage more effective and reducing rebuilds in such systems.
Thank you for bringing attention to this issue. Your insights are valuable to
us, and we appreciate the time you took to document the problem.
I wanted to kindly point out that in this issue template, it would be beneficial
to replace the placeholder `<package>` with the actual, canonical name of the
package you're reporting the issue for. Doing so will provide better context and
facilitate quicker troubleshooting for anyone who reads this issue in the
future.
Best regards
-->
Building this package multiple times does not yield bit-by-bit identical
results, complicating the detection of Continuous Integration (CI) breaches. For
more information on this issue, visit
[reproducible-builds.org](https://reproducible-builds.org/).
Fixing bit-by-bit reproducibility also has additional advantages, such as
avoiding hard-to-reproduce bugs, making content-addressed storage more effective
and reducing rebuilds in such systems.
### Steps To Reproduce
```
nix-build '<nixpkgs>' -A ... --check --keep-failed
```
In the following steps, replace `<package>` with the canonical name of the
package.
You can use `diffoscope` to analyze the differences in the output of the two builds.
#### 1. Build the package
To view the build log of the build that produced the artifact in the binary cache:
This step will build the package. Specific arguments are passed to the command
to keep the build artifacts so we can compare them in case of differences.
Execute the following command:
```
nix-store --read-log $(nix-instantiate '<nixpkgs>' -A ...)
nix-build '<nixpkgs>' -A <package> && nix-build '<nixpkgs>' -A <package> --check --keep-failed
```
Or using the new command line style:
```
nix build nixpkgs#<package> && nix build nixpkgs#<package> --rebuild --keep-failed
```
#### 2. Compare the build artifacts
If the previous command completes successfully, no differences were found and
there's nothing to do, builds are reproducible.
If it terminates with the error message `error: derivation '<X>' may not be
deterministic: output '<Y>' differs from '<Z>'`, use `diffoscope` to investigate
the discrepancies between the two build outputs. You may need to add the
`--exclude-directory-metadata recursive` option to ignore files and directories
metadata (*e.g. timestamp*) differences.
```
nix run nixpkgs#diffoscopeMinimal -- --exclude-directory-metadata recursive <Y> <Z>
```
#### 3. Examine the build log
To examine the build log, use:
```
nix-store --read-log $(nix-instantiate '<nixpkgs>' -A <package>)
```
Or with the new command line style:
```
nix log $(nix path-info --derivation nixpkgs#<package>)
```
### Additional context
(please share the relevant fragment of the diffoscope output here,
and any additional analysis you may have done)

After a pull request is merged, it eventually makes it to the [official Hydra CI](https://hydra.nixos.org/).
Hydra regularly evaluates and builds Nixpkgs, updating [the official channels](https://channels.nixos.org/) when specific Hydra jobs succeeded.
See [Nix Channel Status](https://status.nixos.org/) for the current channels and their state.
Here's a brief overview of the main Git branches and what channels they're used for:
- `master`: The main branch, used for the unstable channels such as `nixpkgs-unstable`, `nixos-unstable` and `nixos-unstable-small`.
- `release-YY.MM` (e.g. `release-23.05`): The NixOS release branches, used for the stable channels such as `nixos-23.05`, `nixos-23.05-small` and `nixpkgs-23.05-darwin`.
- `release-YY.MM` (e.g. `release-23.11`): The NixOS release branches, used for the stable channels such as `nixos-23.11`, `nixos-23.11-small` and `nixpkgs-23.11-darwin`.
When a channel is updated, a corresponding Git branch is also updated to point to the corresponding commit.
So e.g. the [`nixpkgs-unstable` branch](https://github.com/nixos/nixpkgs/tree/nixpkgs-unstable) corresponds to the Git commit from the [`nixpkgs-unstable` channel](https://channels.nixos.org/nixpkgs-unstable).
@@ -375,14 +378,14 @@ The staging workflow exists to batch Hydra builds of many packages together.
It works by directing commits that cause [mass rebuilds][mass-rebuild] to a separate `staging` branch that isn't directly built by Hydra.
Regularly, the `staging` branch is _manually_ merged into a `staging-next` branch to be built by Hydra using the [`nixpkgs:staging-next` jobset](https://hydra.nixos.org/jobset/nixpkgs/staging-next).

Once it is verified that there are no major regressions, it is merged into `master` using [a pull request](https://github.com/NixOS/nixpkgs/pulls?q=head%3Astaging-next).
This is done manually in order to ensure it's a good use of Hydra's computing resources.
By keeping the `staging-next` branch separate from `staging`, this batching does not block developers from merging changes into `staging`.
In order for the `staging` and `staging-next` branches to be up-to-date with the latest commits on `master`, there are regular _automated_ merges from `master` into `staging-next` and `staging`.
This is implemented using GitHub workflows [here](.github/workflows/periodic-merge-6h.yml) and [here](.github/workflows/periodic-merge-24h.yml).

## Commit conventions
- Make sure you read about the [commit conventions](../CONTRIBUTING.md#commit-conventions) common to Nixpkgs as a whole.
- If creating a commit purely for documentation changes, format the commit message in the following way:
```
doc: (documentation summary)
(Motivation for change, relevant links, additional information.)
```
Examples:
* doc: update the kernel config documentation to use `nix-shell`
* doc: add information about `nix-update-script`
Closes #216321.
- If the commit contains more than just documentation changes, follow the commit message format relevant for the rest of the changes.
## Documentation conventions
In an effort to keep the Nixpkgs manual in a consistent style, please follow the conventions below, unless they prevent you from properly documenting something.
In that case, please open an issue about the particular documentation convention and tag it with a "needs: documentation" label.
When needed, each convention explain why it exists, so you can make a decision whether to follow it or not based on your particular case.
Note that these conventions are about the **structure** of the manual (and its source files), not about the content that goes in it.
You, as the writer of documentation, are still in charge of its content.
- Put each sentence in its own line.
This makes reviews and suggestions much easier, since GitHub's review system is based on lines.
It also helps identifying long sentences at a glance.
- Use the [admonition syntax](#admonitions) for callouts and examples.
- Provide at least one example per function, and make examples self-contained.
This is easier to understand for beginners.
It also helps with testing that it actually works especially once we introduce automation.
Example code should be such that it can be passed to `pkgs.callPackage`.
Instead of something like:
```nix
pkgs.dockerTools.buildLayeredImage {
name = "hello";
contents = [ pkgs.hello ];
}
```
Write something like:
```nix
{ dockerTools, hello }:
dockerTools.buildLayeredImage {
name = "hello";
contents = [ hello ];
}
```
- When showing inputs/outputs of any [REPL](https://en.wikipedia.org/wiki/Read%E2%80%93eval%E2%80%93print_loop), such as a shell or the Nix REPL, use a format as you'd see in the REPL, while trying to visually separate inputs from outputs.
This means that for a shell, you should use a format like the following:
```shell
$ nix-build -A hello '<nixpkgs>' \
--option require-sigs false \
--option trusted-substituters file:///tmp/hello-cache \
--option substituters file:///tmp/hello-cache
/nix/store/zhl06z4lrfrkw5rp0hnjjfrgsclzvxpm-hello-2.12.1
```
Note how the input is preceded by `$` on the first line and indented on subsequent lines, and how the output is provided as you'd see on the shell.
For the Nix REPL, you should use a format like the following:
```shell
nix-repl> builtins.attrNames { a = 1; b = 2; }
[ "a" "b" ]
```
Note how the input is preceded by `nix-repl>` and the output is provided as you'd see on the Nix REPL.
- When documenting functions or anything that has inputs/outputs and example usage, use nested headings to clearly separate inputs, outputs, and examples.
Keep examples as the last nested heading, and link to the examples wherever applicable in the documentation.
The purpose of this convention is to provide a familiar structure for navigating the manual, so any reader can expect to find content related to inputs in an "inputs" heading, examples in an "examples" heading, and so on.
An example:
```
## buildImage
Some explanation about the function here.
Describe a particular scenario, and point to [](#ex-dockerTools-buildImage), which is an example demonstrating it.
### Inputs
Documentation for the inputs of `buildImage`.
Perhaps even point to [](#ex-dockerTools-buildImage) again when talking about something specifically linked to it.
### Passthru outputs
Documentation for any passthru outputs of `buildImage`.
### Examples
Note that this is the last nested heading in the `buildImage` section.
:::{.example #ex-dockerTools-buildImage}
# Using `buildImage`
Example of how to use `buildImage` goes here.
:::
```
- Use [definition lists](#definition-lists) to document function arguments, and the attributes of such arguments as well as their [types](https://nixos.org/manual/nix/stable/language/values).
For example:
```markdown
# pkgs.coolFunction
Description of what `coolFunction` does.
## Inputs
`coolFunction` expects a single argument which should be an attribute set, with the following possible attributes:
`name` (String)
: The name of the resulting image.
`tag` (String; _optional_)
: Tag of the generated image.
_Default:_ the output path's hash.
```
#### Examples
To define a referenceable figure use the following fencing:
```markdown
:::{.example #an-attribute-set-example}
# An attribute set example
You can add text before
```nix
{ a = 1; b = 2;}
```
and after code fencing
:::
```
Defining examples through the `example` fencing class adds them to a "List of Examples" section after the Table of Contents.
Though this is not shown in the rendered documentation on nixos.org.
#### Figures
To define a referencable figure use the following fencing:
```markdown
::: {.figure #nixos-logo}
# NixOS Logo
![NixOS logo](./nixos_logo.png)
:::
```
Defining figures through the `figure` fencing class adds them to a `List of Figures` after the `Table of Contents`.
Though this is not shown in the rendered documentation on nixos.org.
#### Footnotes
To add a foonote explanation, use the following syntax:
```markdown
Sometimes it's better to add context [^context] in a footnote.
[^context]: This explanation will be rendered at the end of the chapter.
```
#### Inline comments
Inline comments are supported with following syntax:
```markdown
<!-- This is an inline comment -->
```
The comments will not be rendered in the rendered HTML.
#### Link reference definitions
Links can reference a label, for example, to make the link target reusable:
```markdown
::: {.note}
Reference links can also be used to [shorten URLs][url-id] and keep the markdown readable.

# Build helpers {#part-builders}
A build helper is a function that produces derivations.
:::{.warning}
This is not to be confused with the [`builder` argument of the Nix `derivation` primitive](https://nixos.org/manual/nix/unstable/language/derivations.html), which refers to the executable that produces the build result, or [remote builder](https://nixos.org/manual/nix/stable/advanced-topics/distributed-builds.html), which refers to a remote machine that could run such an executable.
:::
Such a function is usually designed to abstract over a typical workflow for a given programming language or framework.
This allows declaring a build recipe by setting a limited number of options relevant to the particular use case instead of using the `derivation` function directly.
[`stdenv.mkDerivation`](#part-stdenv) is the most widely used build helper, and serves as a basis for many others.
In addition, it offers various options to customize parts of the builds.
There is no uniform interface for build helpers.
[Trivial build helpers](#chap-trivial-builders) and [fetchers](#chap-pkgs-fetchers) have various input types for convenience.
[Language- or framework-specific build helpers](#chap-language-support) usually follow the style of `stdenv.mkDerivation`, which accepts an attribute set or a fixed-point function taking an attribute set.

# Fetchers {#chap-pkgs-fetchers}
Building software with Nix often requires downloading source code and other files from the internet.
To this end, Nixpkgs provides *fetchers*: functions to obtain remote sources via various protocols and services.
Nixpkgs fetchers differ from built-in fetchers such as [`builtins.fetchTarball`](https://nixos.org/manual/nix/stable/language/builtins.html#builtins-fetchTarball):
- A built-in fetcher will download and cache files at evaluation time and produce a [store path](https://nixos.org/manual/nix/stable/glossary#gloss-store-path).
A Nixpkgs fetcher will create a ([fixed-output](https://nixos.org/manual/nix/stable/glossary#gloss-fixed-output-derivation)) [derivation](https://nixos.org/manual/nix/stable/language/derivations), and files are downloaded at build time.
- Built-in fetchers will invalidate their cache after [`tarball-ttl`](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-tarball-ttl) expires, and will require network activity to check if the cache entry is up to date.
Nixpkgs fetchers only re-download if the specified hash changes or the store object is not otherwise available.
- Built-in fetchers do not use [substituters](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-substituters).
Derivations produced by Nixpkgs fetchers will use any configured binary cache transparently.
This significantly reduces the time needed to evaluate the entirety of Nixpkgs, and allows [Hydra](https://nixos.org/hydra) to retain and re-distribute sources used by Nixpkgs in the [public binary cache](https://cache.nixos.org).
For these reasons, built-in fetchers are not allowed in Nixpkgs source code.
The following table shows an overview of the differences:
| Fetchers | Download | Output | Cache | Re-download when |
|-|-|-|-|-|
| `builtins.fetch*` | evaluation time | store path | `/nix/store`, `~/.cache/nix` | `tarball-ttl` expires, cache miss in `~/.cache/nix`, output store object not in local store |
| `pkgs.fetch*` | build time | derivation | `/nix/store`, substituters | output store object not available |
## Caveats {#chap-pkgs-fetchers-caveats}
The fact that the hash belongs to the Nix derivation output and not the file itself can lead to confusion.
For example, consider the following fetcher:
```nix
fetchurl {
url = "http://www.example.org/hello-1.0.tar.gz";
hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
};
```
A common mistake is to update a fetchers URL, or a version parameter, without updating the hash.
```nix
fetchurl {
url = "http://www.example.org/hello-1.1.tar.gz";
hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
};
```
**This will reuse the old contents**.
Remember to invalidate the hash argument, in this case by setting the `hash` attribute to an empty string.
```nix
fetchurl {
url = "http://www.example.org/hello-1.1.tar.gz";
hash = "";
};
```
Use the resulting error message to determine the correct hash.
```
error: hash mismatch in fixed-output derivation '/path/to/my.drv':
specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
got: sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=
```
A similar problem arises while testing changes to a fetcher's implementation. If the output of the derivation already exists in the Nix store, test failures can go undetected. The [`invalidateFetcherByDrvHash`](#tester-invalidateFetcherByDrvHash) function helps prevent reusing cached derivations.
## `fetchurl` and `fetchzip` {#fetchurl}
Two basic fetchers are `fetchurl` and `fetchzip`. Both of these have two required arguments, a URL and a hash. The hash is typically `hash`, although many more hash algorithms are supported. Nixpkgs contributors are currently recommended to use `hash`. This hash will be used by Nix to identify your source. A typical usage of `fetchurl` is provided below.
```nix
{ stdenv, fetchurl }:
stdenv.mkDerivation {
name = "hello";
src = fetchurl {
url = "http://www.example.org/hello.tar.gz";
hash = "sha256-BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=";
};
}
```
The main difference between `fetchurl` and `fetchzip` is in how they store the contents. `fetchurl` will store the unaltered contents of the URL within the Nix store. `fetchzip` on the other hand, will decompress the archive for you, making files and directories directly accessible in the future. `fetchzip` can only be used with archives. Despite the name, `fetchzip` is not limited to .zip files and can also be used with any tarball.
## `fetchpatch` {#fetchpatch}
`fetchpatch` works very similarly to `fetchurl` with the same arguments expected. It expects patch files as a source and performs normalization on them before computing the checksum. For example, it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
- `relative`: Similar to using `git-diff`'s `--relative` flag, only keep changes inside the specified directory, making paths relative to it.
- `stripLen`: Remove the first `stripLen` components of pathnames in the patch.
- `decode`: Pipe the downloaded data through this command before processing it as a patch.
- `extraPrefix`: Prefix pathnames by this string.
- `excludes`: Exclude files matching these patterns (applies after the above arguments).
- `includes`: Include only files matching these patterns (applies after the above arguments).
- `revert`: Revert the patch.
Note that because the checksum is computed after applying these effects, using or modifying these arguments will have no effect unless the `hash` argument is changed as well.
Most other fetchers return a directory rather than a single file.
## `fetchDebianPatch` {#fetchdebianpatch}
A wrapper around `fetchpatch`, which takes:
- `patch` and `hash`: the patch's filename,
and its hash after normalization by `fetchpatch` ;
- `pname`: the Debian source package's name ;
- `version`: the upstream version number ;
- `debianRevision`: the [Debian revision number] if applicable ;
- the `area` of the Debian archive: `main` (default), `contrib`, or `non-free`.
Here is an example of `fetchDebianPatch` in action:
```nix
{ lib
, fetchDebianPatch
, buildPythonPackage
}:
buildPythonPackage rec {
pname = "pysimplesoap";
version = "1.16.2";
src = ...;
patches = [
(fetchDebianPatch {
inherit pname version;
debianRevision = "5";
name = "Add-quotes-to-SOAPAction-header-in-SoapClient.patch";
hash = "sha256-xA8Wnrpr31H8wy3zHSNfezFNjUJt1HbSXn3qUMzeKc0=";
})
];
...
}
```
Patches are fetched from `sources.debian.org`, and so must come from a
package version that was uploaded to the Debian archive. Packages may
be removed from there once that specific version isn't in any suite
anymore (stable, testing, unstable, etc.), so maintainers should use
`copy-tarballs.pl` to archive the patch if it needs to be available
longer-term.
[Debian revision number]: https://www.debian.org/doc/debian-policy/ch-controlfields.html#version
## `fetchsvn` {#fetchsvn}
Used with Subversion. Expects `url` to a Subversion directory, `rev`, and `hash`.
## `fetchgit` {#fetchgit}
Used with Git. Expects `url` to a Git repo, `rev`, and `hash`. `rev` in this case can be full the git commit id (SHA1 hash) or a tag name like `refs/tags/v1.0`.
Additionally, the following optional arguments can be given: `fetchSubmodules = true` makes `fetchgit` also fetch the submodules of a repository. If `deepClone` is set to true, the entire repository is cloned as opposing to just creating a shallow clone. `deepClone = true` also implies `leaveDotGit = true` which means that the `.git` directory of the clone won't be removed after checkout.
If only parts of the repository are needed, `sparseCheckout` can be used. This will prevent git from fetching unnecessary blobs from server, see [git sparse-checkout](https://git-scm.com/docs/git-sparse-checkout) for more information:
```nix
{ stdenv, fetchgit }:
stdenv.mkDerivation {
name = "hello";
src = fetchgit {
url = "https://...";
sparseCheckout = [
"directory/to/be/included"
"another/directory"
];
hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
};
}
```
## `fetchfossil` {#fetchfossil}
Used with Fossil. Expects `url` to a Fossil archive, `rev`, and `hash`.
## `fetchcvs` {#fetchcvs}
Used with CVS. Expects `cvsRoot`, `tag`, and `hash`.
## `fetchhg` {#fetchhg}
Used with Mercurial. Expects `url`, `rev`, and `hash`.
A number of fetcher functions wrap part of `fetchurl` and `fetchzip`. They are mainly convenience functions intended for commonly used destinations of source code in Nixpkgs. These wrapper fetchers are listed below.
## `fetchFromGitea` {#fetchfromgitea}
`fetchFromGitea` expects five arguments. `domain` is the gitea server name. `owner` is a string corresponding to the Gitea user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every Gitea HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available but `hash` is currently preferred.
## `fetchFromGitHub` {#fetchfromgithub}
`fetchFromGitHub` expects four arguments. `owner` is a string corresponding to the GitHub user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every GitHub HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available, but `hash` is currently preferred.
To use a different GitHub instance, use `githubBase` (defaults to `"github.com"`).
`fetchFromGitHub` uses `fetchzip` to download the source archive generated by GitHub for the specified revision. If `leaveDotGit`, `deepClone` or `fetchSubmodules` are set to `true`, `fetchFromGitHub` will use `fetchgit` instead. Refer to its section for documentation of these options.
## `fetchFromGitLab` {#fetchfromgitlab}
This is used with GitLab repositories. It behaves similarly to `fetchFromGitHub`, and expects `owner`, `repo`, `rev`, and `hash`.
To use a specific GitLab instance, use `domain` (defaults to `"gitlab.com"`).
## `fetchFromGitiles` {#fetchfromgitiles}
This is used with Gitiles repositories. The arguments expected are similar to `fetchgit`.
## `fetchFromBitbucket` {#fetchfrombitbucket}
This is used with BitBucket repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSavannah` {#fetchfromsavannah}
This is used with Savannah repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromRepoOrCz` {#fetchfromrepoorcz}
This is used with repo.or.cz repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSourcehut` {#fetchfromsourcehut}
This is used with sourcehut repositories. Similar to `fetchFromGitHub` above,
it expects `owner`, `repo`, `rev` and `hash`, but don't forget the tilde (~)
in front of the username! Expected arguments also include `vc` ("git" (default)
or "hg"), `domain` and `fetchSubmodules`.
If `fetchSubmodules` is `true`, `fetchFromSourcehut` uses `fetchgit`
or `fetchhg` with `fetchSubmodules` or `fetchSubrepos` set to `true`,
respectively. Otherwise, the fetcher uses `fetchzip`.
## `requireFile` {#requirefile}
`requireFile` allows requesting files that cannot be fetched automatically, but whose content is known.
This is a useful last-resort workaround for license restrictions that prohibit redistribution, or for downloads that are only accessible after authenticating interactively in a browser.
If the requested file is present in the Nix store, the resulting derivation will not be built, because its expected output is already available.
Otherwise, the builder will run, but fail with a message explaining to the user how to provide the file. The following code, for example:
```
requireFile {
name = "jdk-${version}_linux-x64_bin.tar.gz";
url = "https://www.oracle.com/java/technologies/javase-jdk11-downloads.html";
hash = "sha256-lL00+F7jjT71nlKJ7HRQuUQ7kkxVYlZh//5msD8sjeI=";
}
```
results in this error message:
```
***
Unfortunately, we cannot download file jdk-11.0.10_linux-x64_bin.tar.gz automatically.
Please go to https://www.oracle.com/java/technologies/javase-jdk11-downloads.html to download it yourself, and add it to the Nix store
using either
nix-store --add-fixed sha256 jdk-11.0.10_linux-x64_bin.tar.gz
or
nix-prefetch-url --type sha256 file:///path/to/jdk-11.0.10_linux-x64_bin.tar.gz

```
## `fetchtorrent` {#fetchtorrent}
`fetchtorrent` expects two arguments. `url` which can either be a Magnet URI (Magnet Link) such as `magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c` or an HTTP URL pointing to a `.torrent` file. It can also take a `config` argument which will craft a `settings.json` configuration file and give it to `transmission`, the underlying program that is performing the fetch. The available config options for `transmission` can be found [here](https://github.com/transmission/transmission/blob/main/docs/Editing-Configuration-Files.md#options)
```
{ fetchtorrent }:
fetchtorrent {
config = { peer-limit-global = 100; };
url = "magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c";
sha256 = "";
}
```
### Parameters {#fetchtorrent-parameters}
- `url`: Magnet URI (Magnet Link) such as `magnet:?xt=urn:btih:dd8255ecdc7ca55fb0bbf81323d87062db1f6d1c` or an HTTP URL pointing to a `.torrent` file.
- `backend`: Which bittorrent program to use. Default: `"transmission"`. Valid values are `"rqbit"` or `"transmission"`. These are the two most suitable torrent clients for fetching in a fixed-output derivation at the time of writing, as they can be easily exited after usage. `rqbit` is written in Rust and has a smaller closure size than `transmission`, and the performance and peer discovery properties differs between these clients, requiring experimentation to decide upon which is the best.
- `config`: When using `transmission` as the `backend`, a json configuration can
be supplied to transmission. Refer to the [upstream documentation](https://github.com/transmission/transmission/blob/main/docs/Editing-Configuration-Files.md) for information on how to configure.

# pkgs.appimageTools {#sec-pkgs-appimageTools}
`pkgs.appimageTools` is a set of functions for extracting and wrapping [AppImage](https://appimage.org/) files.
They are meant to be used if traditional packaging from source is infeasible, or if it would take too long.
To quickly run an AppImage file, `pkgs.appimage-run` can be used as well.
::: {.warning}
The `appimageTools` API is unstable and may be subject to backwards-incompatible changes in the future.
:::
## Wrapping {#ssec-pkgs-appimageTools-wrapping}
Use `wrapType2` to wrap any AppImage.
This will create a FHS environment with many packages [expected to exist](https://github.com/AppImage/pkg2appimage/blob/master/excludelist) for the AppImage to work.
`wrapType2` expects an argument with the `src` attribute, and either a `name` attribute or `pname` and `version` attributes.
It will eventually call into [`buildFHSEnv`](#sec-fhs-environments), and any extra attributes in the argument to `wrapType2` will be passed through to it.
This means that you can pass the `extraInstallCommands` attribute, for example, and it will have the same effect as described in [`buildFHSEnv`](#sec-fhs-environments).
::: {.note}
In the past, `appimageTools` provided both `wrapType1` and `wrapType2`, to be used depending on the type of AppImage that was being wrapped.
However, [those were unified early 2020](https://github.com/NixOS/nixpkgs/pull/81833), meaning that both `wrapType1` and `wrapType2` have the same behaviour now.
:::
:::{.example #ex-wrapping-appimage-from-github}
# Wrapping an AppImage from GitHub
```nix
{ appimageTools, fetchurl }:
let
pname = "nuclear";
version = "0.6.30";
src = fetchurl {
url = "https://github.com/nukeop/nuclear/releases/download/v${version}/${pname}-v${version}.AppImage";
hash = "sha256-he1uGC1M/nFcKpMM9JKY4oeexJcnzV0ZRxhTjtJz6xw=";
};
in
appimageTools.wrapType2 {
inherit pname version src;
}
```
:::
The argument passed to `wrapType2` can also contain an `extraPkgs` attribute, which allows you to include additional packages inside the FHS environment your AppImage is going to run in.
`extraPkgs` must be a function that returns a list of packages.
There are a few ways to learn which dependencies an application needs:
- Looking through the extracted AppImage files, reading its scripts and running `patchelf` and `ldd` on its executables.
This can also be done in `appimage-run`, by setting `APPIMAGE_DEBUG_EXEC=bash`.
- Running `strace -vfefile` on the wrapped executable, looking for libraries that can't be found.

};
in appimageTools.wrapType2 {
inherit pname version src;
extraPkgs = pkgs: [ pkgs.at-spi2-core ];
}
```
:::
## Extracting {#ssec-pkgs-appimageTools-extracting}
Use `extract` if you need to extract the contents of an AppImage.
This is usually used in Nixpkgs to install extra files in addition to [wrapping](#ssec-pkgs-appimageTools-wrapping) the AppImage.
`extract` expects an argument with the `src` attribute, and either a `name` attribute or `pname` and `version` attributes.
::: {.note}
In the past, `appimageTools` provided both `extractType1` and `extractType2`, to be used depending on the type of AppImage that was being extracted.
However, [those were unified early 2020](https://github.com/NixOS/nixpkgs/pull/81572), meaning that both `extractType1` and `extractType2` have the same behaviour as `extract` now.
:::
:::{.example #ex-extracting-appimage}
# Extracting an AppImage to install extra files
This example was adapted from a real package in Nixpkgs to show how `extract` is usually used in combination with `wrapType2`.
Note how `appimageContents` is used in `extraInstallCommands` to install additional files that were extracted from the AppImage.
```nix
{ appimageTools, fetchurl }:
let
pname = "irccloud";
version = "0.16.0";
src = fetchurl {
url = "https://github.com/irccloud/irccloud-desktop/releases/download/v${version}/IRCCloud-${version}-linux-x86_64.AppImage";
sha256 = "sha256-/hMPvYdnVB1XjKgU2v47HnVvW4+uC3rhRjbucqin4iI=";

appimageContents = appimageTools.extract {

};

substituteInPlace $out/share/applications/irccloud.desktop \
--replace 'Exec=AppRun' 'Exec=${pname}'
'';
}
```
:::
The argument passed to `extract` can also contain a `postExtract` attribute, which allows you to execute additional commands after the files are extracted from the AppImage.
`postExtract` must be a string with commands to run.
:::{.example #ex-extracting-appimage-with-postextract}
# Extracting an AppImage to install extra files, using `postExtract`
This is a rewrite of [](#ex-extracting-appimage) to use `postExtract`.

# 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.
`mkBinaryCache` expects an argument with the `rootPaths` attribute.
`rootPaths` must be a list of derivations.
The transitive closure of these derivations' outputs will be copied into the cache.
::: {.note}
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.
:::
[]{#sec-pkgs-binary-cache-example}
:::{.example #ex-mkbinarycache-copying-package-closure}
# Copying a package and its closure to another machine with `mkBinaryCache`
The following derivation will construct a flat-file binary cache containing the closure of `hello`.
```nix
{ mkBinaryCache, hello }:
mkBinaryCache {
rootPaths = [hello];
}
```
Build the cache on a machine.
Note that the command still builds the exact nix package above, but adds some boilerplate to build it directly from an expression.
```shellSession
$ nix-build -E 'let pkgs = import <nixpkgs> {}; in pkgs.callPackage ({ mkBinaryCache, hello }: mkBinaryCache { rootPaths = [hello]; }) {}'
/nix/store/azf7xay5xxdnia4h9fyjiv59wsjdxl0g-binary-cache
```
Copy the resulting directory to another machine, which we'll call `host2`:
```shellSession
$ scp result host2:/tmp/hello-cache
```
At this point, the cache can be used as a substituter when building derivations on `host2`:
```shellSession
$ nix-build -A hello '<nixpkgs>' \
--option require-sigs false \
--option trusted-substituters file:///tmp/hello-cache \
--option substituters file:///tmp/hello-cache
/nix/store/zhl06z4lrfrkw5rp0hnjjfrgsclzvxpm-hello-2.12.1

# pkgs.checkpointBuildTools {#sec-checkpoint-build}
`pkgs.checkpointBuildTools` provides a way to build derivations incrementally. It consists of two functions to make checkpoint builds using Nix possible.
For hermeticity, Nix derivations do not allow any state to be carried over between builds, making a transparent incremental build within a derivation impossible.
However, we can tell Nix explicitly what the previous build state was, by representing that previous state as a derivation output. This allows the passed build state to be used for an incremental build.
To change a normal derivation to a checkpoint based build, these steps must be taken:
- apply `prepareCheckpointBuild` on the desired derivation, e.g.
```nix
checkpointArtifacts = (pkgs.checkpointBuildTools.prepareCheckpointBuild pkgs.virtualbox);
```
- change something you want in the sources of the package, e.g. use a source override:
```nix
changedVBox = pkgs.virtualbox.overrideAttrs (old: {
src = path/to/vbox/sources;
});
```
- use `mkCheckpointBuild changedVBox checkpointArtifacts`
- enjoy shorter build times
## Example {#sec-checkpoint-build-example}
```nix
{ pkgs ? import <nixpkgs> {} }:
let
inherit (pkgs.checkpointBuildTools)
prepareCheckpointBuild
mkCheckpointBuild
;
helloCheckpoint = prepareCheckpointBuild pkgs.hello;
changedHello = pkgs.hello.overrideAttrs (_: {
doCheck = false;

# fakeNss {#sec-fakeNss}
Provides `/etc/passwd` and `/etc/group` files that contain `root` and `nobody`, allowing user/group lookups to work in binaries that insist on doing those.
This might be a better choice than a custom script running `useradd` and related utilities if you only need those files to exist with some entries.
`fakeNss` also provides `/etc/nsswitch.conf`, configuring NSS host resolution to first check `/etc/hosts` before checking DNS, since the default in the absence of a config file (`dns [!UNAVAIL=return] files`) is quite unexpected.
It also creates an empty directory at `/var/empty` because it uses that as the home directory for the `root` and `nobody` users.
The `/var/empty` directory can also be used as a `chroot` target to prevent file access in processes that do not need to access files, if your container runs such processes.
The user entries created by `fakeNss` use the `/bin/sh` shell, which is not provided by `fakeNss` because in most cases it won't be used.
If you need that to be available, see [`dockerTools.binSh`](#sssec-pkgs-dockerTools-helpers-binSh) or provide your own.
## Inputs {#sec-fakeNss-inputs}
`fakeNss` is made available in Nixpkgs as a package rather than a function, but it has two attributes that can be overridden and might be useful in particular cases.
For more details on how overriding works, see [](#ex-fakeNss-overriding) and [](#sec-pkg-override).
`extraPasswdLines` (List of Strings; _optional_)
: A list of lines that will be added to `/etc/passwd`.
Useful if extra users need to exist in the output of `fakeNss`.
If `extraPasswdLines` is specified, it will **not** override the `root` and `nobody` entries created by `fakeNss`.
Those entries will always exist.
Lines specified here must follow the format in {manpage}`passwd(5)`.
_Default value:_ `[]`.
`extraGroupLines` (List of Strings; _optional_)
: A list of lines that will be added to `/etc/group`.
Useful if extra groups need to exist in the output of `fakeNss`.
If `extraGroupLines` is specified, it will **not** override the `root` and `nobody` entries created by `fakeNss`.
Those entries will always exist.
Lines specified here must follow the format in {manpage}`group(5)`.
_Default value:_ `[]`.
## Examples {#sec-fakeNss-examples}
:::{.example #ex-fakeNss-dockerTools-buildImage}
# Using `fakeNss` with `dockerTools.buildImage`
This example shows how to use `fakeNss` as-is.
It is useful with functions in `dockerTools` to allow building Docker images that have the `/etc/passwd` and `/etc/group` files.
This example includes the `hello` binary in the image so it can do something besides just have the extra files.
```nix
{ dockerTools, fakeNss, hello }:
dockerTools.buildImage {
name = "image-with-passwd";
tag = "latest";
copyToRoot = [ fakeNss hello ];
config = {
Cmd = [ "/bin/hello" ];

## `hasPkgConfigModules` {#tester-hasPkgConfigModules}
<!-- Old anchor name so links still work -->
[]{#tester-hasPkgConfigModule}
Checks whether a package exposes a given list of `pkg-config` modules.
If the `moduleNames` argument is omitted, `hasPkgConfigModules` will use `meta.pkgConfigModules`.
:::{.example #ex-haspkgconfigmodules-defaultvalues}
# Check that `pkg-config` modules are exposed using default values

package = finalAttrs.finalPackage;
moduleNames = [ "libfoo" ];
};
```
:::
## `testVersion` {#tester-testVersion}
Checks that the output from running a command contains the specified version string in it as a whole word.
Although simplistic, this test assures that the main program can run.
While there's no substitute for a real test case, it does catch dynamic linking errors and such.
It also provides some protection against accidentally building the wrong version, for example when using an "old" hash in a fixed-output derivation.
By default, the command to be run will be inferred from the given `package` attribute:
it will check `meta.mainProgram` first, and fall back to `pname` or `name`.
The default argument to the command is `--version`, and the version to be checked will be inferred from the given `package` attribute as well.
:::{.example #ex-testversion-hello}
# Check a program version using all the default values
This example will run the command `hello --version`, and then check that the version of the `hello` package is in the output of the command.
```nix
passthru.tests.version = testers.testVersion { package = hello; };
```
:::
:::{.example #ex-testversion-different-commandversion}
# Check the program version using a specified command and expected version string
This example will run the command `leetcode -V`, and then check that `leetcode 0.4.2` is in the output of the command as a whole word (separated by whitespaces).
This means that an output like "leetcode 0.4.21" would fail the tests, and an output like "You're running leetcode 0.4.2" would pass the tests.
A common usage of the `version` attribute is to specify `version = "v${version}"`.
```nix
version = "0.4.2";
passthru.tests.version = testers.testVersion {
package = leetcode-cli;
command = "leetcode -V";
version = "leetcode ${version}";
};
```
:::
## `testBuildFailure` {#tester-testBuildFailure}
Make sure that a build does not succeed. This is useful for testing testers.
This returns a derivation with an override on the builder, with the following effects:
- Fail the build when the original builder succeeds
- Move `$out` to `$out/result`, if it exists (assuming `out` is the default output)
- Save the build log to `$out/testBuildFailure.log` (same)
While `testBuildFailure` is designed to keep changes to the original builder's environment to a minimum, some small changes are inevitable:
- The file `$TMPDIR/testBuildFailure.log` is present. It should not be deleted.
- `stdout` and `stderr` are a pipe instead of a tty. This could be improved.
- One or two extra processes are present in the sandbox during the original builder's execution.
- The derivation and output hashes are different, but not unusual.
- The derivation includes a dependency on `buildPackages.bash` and `expect-failure.sh`, which is built to include a transitive dependency on `buildPackages.coreutils` and possibly more.
These are not added to `PATH` or any other environment variable, so they should be hard to observe.
:::{.example #ex-testBuildFailure-showingenvironmentchanges}
# Check that a build fails, and verify the changes made during build
```nix
runCommand "example" {
failed = testers.testBuildFailure (runCommand "fail" {} ''
echo ok-ish >$out
echo failing though
exit 3
'');
} ''
grep -F 'ok-ish' $failed/result
grep -F 'failing though' $failed/testBuildFailure.log
[[ 3 = $(cat $failed/testBuildFailure.exit) ]]
touch $out
'';

## `testEqualContents` {#tester-equalContents}
Check that two paths have the same contents.
:::{.example #ex-testEqualContents-toyexample}

testers.testEqualContents {
assertion = "sed -e performs replacement";
expected = writeText "expected" ''

actual = runCommand "actual" {
# not really necessary for a package that's in stdenv
nativeBuildInputs = [ gnused ];
base = writeText "base" ''
foo bar baz
'';
} ''
sed -e 's/bar/baz/g' $base >$out
'';
}
```
:::
## `testEqualDerivation` {#tester-testEqualDerivation}
Checks that two packages produce the exact same build instructions.
This can be used to make sure that a certain difference of configuration, such as the presence of an overlay does not cause a cache miss.
When the derivations are equal, the return value is an empty file.
Otherwise, the build log explains the difference via `nix-diff`.
:::{.example #ex-testEqualDerivation-hello}
# Check that two packages produce the same derivation
```nix
testers.testEqualDerivation
"The hello package must stay the same when enabling checks."
hello
(hello.overrideAttrs(o: { doCheck = true; }))
```
:::
## `invalidateFetcherByDrvHash` {#tester-invalidateFetcherByDrvHash}
Use the derivation hash to invalidate the output via name, for testing.
Type: `(a@{ name, ... } -> Derivation) -> a -> Derivation`
Normally, fixed output derivations can and should be cached by their output hash only, but for testing we want to re-fetch everytime the fetcher changes.
Changes to the fetcher become apparent in the drvPath, which is a hash of how to fetch, rather than a fixed store path.
By inserting this hash into the name, we can make sure to re-run the fetcher every time the fetcher changes.
This relies on the assumption that Nix isn't clever enough to reuse its database of local store contents to optimize fetching.
You might notice that the "salted" name derives from the normal invocation, not the final derivation.
`invalidateFetcherByDrvHash` has to invoke the fetcher function twice:
once to get a derivation hash, and again to produce the final fixed output derivation.
:::{.example #ex-invalidateFetcherByDrvHash-nix}
# Prevent nix from reusing the output of a fetcher
```nix
tests.fetchgit = testers.invalidateFetcherByDrvHash fetchgit {
name = "nix-source";
url = "https://github.com/NixOS/nix";

:::
## `nixosTest` {#tester-nixosTest}

NOTE: This function is primarily for external use. NixOS itself uses `make-test-python.nix` directly. Packages defined in Nixpkgs [reuse NixOS tests via `nixosTests`, plural](#ssec-nixos-tests-linking).
It is mostly equivalent to the function `import ./make-test-python.nix` from the [NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests), except that the current application of Nixpkgs (`pkgs`) will be used, instead of letting NixOS invoke Nixpkgs anew.
If a test machine needs to set NixOS options under `nixpkgs`, it must set only the `nixpkgs.pkgs` option.
### Parameter {#tester-nixosTest-parameter}

# Trivial build helpers {#chap-trivial-builders}
Nixpkgs provides a variety of wrapper functions that help build commonly useful derivations.
Like [`stdenv.mkDerivation`](#sec-using-stdenv), each of these build helpers creates a derivation, but the arguments passed are different (usually simpler) from those required by `stdenv.mkDerivation`.
## `runCommand` {#trivial-builder-runCommand}
`runCommand :: String -> AttrSet -> String -> Derivation`
`runCommand name drvAttrs buildCommand` returns a derivation that is built by running the specified shell commands.
`name :: String`
: The name that Nix will append to the store path in the same way that `stdenv.mkDerivation` uses its `name` attribute.
`drvAttr :: AttrSet`
: Attributes to pass to the underlying call to [`stdenv.mkDerivation`](#chap-stdenv).
`buildCommand :: String`
: Shell commands to run in the derivation builder.
::: {.note}
You have to create a file or directory `$out` for Nix to be able to run the builder successfully.
:::
::: {.example #ex-runcommand-simple}
# Invocation of `runCommand`
```nix
(import <nixpkgs> {}).runCommand "my-example" {} ''
echo My example command is running
mkdir $out
echo I can write data to the Nix store > $out/message
echo I can also run basic commands like:
echo ls
ls
echo whoami
whoami
echo date
date
''
```
:::
## `runCommandCC` {#trivial-builder-runCommandCC}
This works just like `runCommand`. The only difference is that it also provides a C compiler in `buildCommand`'s environment. To minimize your dependencies, you should only use this if you are sure you will need a C compiler as part of running your command.
## `runCommandLocal` {#trivial-builder-runCommandLocal}
Variant of `runCommand` that forces the derivation to be built locally, it is not substituted. This is intended for very cheap commands (<1s execution time). It saves on the network round-trip and can speed up a build.
::: {.note}
This sets [`allowSubstitutes` to `false`](https://nixos.org/nix/manual/#adv-attr-allowSubstitutes), so only use `runCommandLocal` if you are certain the user will always have a builder for the `system` of the derivation. This should be true for most trivial use cases (e.g., just copying some files to a different location or adding symlinks) because there the `system` is usually the same as `builtins.currentSystem`.
:::
## Writing text files {#trivial-builder-text-writing}
Nixpkgs provides the following functions for producing derivations which write text files or executable scripts into the Nix store.
They are useful for creating files from Nix expression, and are all implemented as convenience wrappers around `writeTextFile`.
Each of these functions will cause a derivation to be produced.
When you coerce the result of each of these functions to a string with [string interpolation](https://nixos.org/manual/nix/stable/language/string-interpolation) or [`builtins.toString`](https://nixos.org/manual/nix/stable/language/builtins#builtins-toString), it will evaluate to the [store path](https://nixos.org/manual/nix/stable/store/store-path) of this derivation.
:::: {.note}
Some of these functions will put the resulting files within a directory inside the [derivation output](https://nixos.org/manual/nix/stable/language/derivations#attr-outputs).
If you need to refer to the resulting files somewhere else in a Nix expression, append their path to the derivation's store path.
For example, if the file destination is a directory:
```nix
my-file = writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
destination = "/share/my-file";
}
```
Remember to append "/share/my-file" to the resulting store path when using it elsewhere:
```nix
writeShellScript "evaluate-my-file.sh" ''
cat ${my-file}/share/my-file
'';
```
::::
### `writeTextFile` {#trivial-builder-writeTextFile}
Write a text file to the Nix store.
`writeTextFile` takes an attribute set with the following possible attributes:
`name` (String)
: Corresponds to the name used in the Nix store path identifier.
`text` (String)
: The contents of the file.
`executable` (Bool, _optional_)
: Make this file have the executable bit set.
Default: `false`
`destination` (String, _optional_)
: A subpath under the derivation's output path into which to put the file.
Subdirectories are created automatically when the derivation is realised.
By default, the store path itself will be a file containing the text contents.
Default: `""`
`checkPhase` (String, _optional_)
: Commands to run after generating the file.
Default: `""`
`meta` (Attribute set, _optional_)
: Additional metadata for the derivation.
Default: `{}`
`allowSubstitutes` (Bool, _optional_)
: Whether to allow substituting from a binary cache.
Passed through to [`allowSubsitutes`](https://nixos.org/manual/nix/stable/language/advanced-attributes#adv-attr-allowSubstitutes) of the underlying call to `builtins.derivation`.
It defaults to `false`, as running the derivation's simple `builder` executable locally is assumed to be faster than network operations.
Set it to true if the `checkPhase` step is expensive.
Default: `false`
`preferLocalBuild` (Bool, _optional_)
: Whether to prefer building locally, even if faster [remote build machines](https://nixos.org/manual/nix/stable/command-ref/conf-file#conf-substituters) are available.
Passed through to [`preferLocalBuild`](https://nixos.org/manual/nix/stable/language/advanced-attributes#adv-attr-preferLocalBuild) of the underlying call to `builtins.derivation`.
It defaults to `true` for the same reason `allowSubstitutes` defaults to `false`.
Default: `true`
The resulting store path will include some variation of the name, and it will be a file unless `destination` is used, in which case it will be a directory.
::: {.example #ex-writeTextFile}
# Usage 1 of `writeTextFile`
Write `my-file` to `/nix/store/<store path>/some/subpath/my-cool-script`, making it executable.
Also run a check on the resulting file in a `checkPhase`, and supply values for the less-used options.
```nix
writeTextFile {
name = "my-cool-script";
text = ''
#!/bin/sh
echo "This is my cool script!"
'';
executable = true;
destination = "/some/subpath/my-cool-script";
checkPhase = ''
${pkgs.shellcheck}/bin/shellcheck $out/some/subpath/my-cool-script
'';
meta = {
license = pkgs.lib.licenses.cc0;
};
allowSubstitutes = true;
preferLocalBuild = false;
};
```
:::
::: {.example #ex2-writeTextFile}
# Usage 2 of `writeTextFile`
Write the string `Contents of File` to `/nix/store/<store path>`.
See also the [](#trivial-builder-writeText) helper function.
```nix
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
}
```
:::
::: {.example #ex3-writeTextFile}
# Usage 3 of `writeTextFile`
Write an executable script `my-script` to `/nix/store/<store path>/bin/my-script`.
See also the [](#trivial-builder-writeScriptBin) helper function.
```nix
writeTextFile {
name = "my-script";
text = ''
echo "hi"
'';
executable = true;
destination = "/bin/my-script";
}
```
:::
### `writeText` {#trivial-builder-writeText}
Write a text file to the Nix store
`writeText` takes the following arguments:
a string.
`name` (String)
: The name used in the Nix store path.
`text` (String)
: The contents of the file.
The store path will include the name, and it will be a file.
::: {.example #ex-writeText}
# Usage of `writeText`
Write the string `Contents of File` to `/nix/store/<store path>`:
```nix
writeText "my-file"
''
Contents of File
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
}
```
### `writeTextDir` {#trivial-builder-writeTextDir}
Write a text file within a subdirectory of the Nix store.
`writeTextDir` takes the following arguments:
`path` (String)
: The destination within the Nix store path under which to create the file.
`text` (String)
: The contents of the file.
The store path will be a directory.
::: {.example #ex-writeTextDir}
# Usage of `writeTextDir`
Write the string `Contents of File` to `/nix/store/<store path>/share/my-file`:
```nix
writeTextDir "share/my-file"
''
Contents of File
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
destination = "share/my-file";
}
```
### `writeScript` {#trivial-builder-writeScript}
Write an executable script file to the Nix store.
`writeScript` takes the following arguments:
`name` (String)
: The name used in the Nix store path.
`text` (String)
: The contents of the file.
The created file is marked as executable.
The store path will include the name, and it will be a file.
::: {.example #ex-writeScript}
# Usage of `writeScript`
Write the string `Contents of File` to `/nix/store/<store path>` and make the file executable.
```nix
writeScript "my-file"
''
Contents of File
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
executable = true;
}
```
### `writeScriptBin` {#trivial-builder-writeScriptBin}
Write a script within a `bin` subirectory of a directory in the Nix store.
This is for consistency with the convention of software packages placing executables under `bin`.
`writeScriptBin` takes the following arguments:
`name` (String)
: The name used in the Nix store path and within the file created under the store path.
`text` (String)
: The contents of the file.
The created file is marked as executable.
The file's contents will be put into `/nix/store/<store path>/bin/<name>`.
The store path will include the the name, and it will be a directory.
::: {.example #ex-writeScriptBin}
# Usage of `writeScriptBin`
```nix
writeScriptBin "my-script"
''
echo "hi"
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-script";
text = ''
echo "hi"
'';
executable = true;
destination = "bin/my-script"
}
```
### `writeShellScript` {#trivial-builder-writeShellScript}
Write a Bash script to the store.
`writeShellScript` takes the following arguments:
`name` (String)
: The name used in the Nix store path.
`text` (String)
: The contents of the file.
The created file is marked as executable.
The store path will include the name, and it will be a file.
This function is almost exactly like [](#trivial-builder-writeScript), except that it prepends to the file a [shebang](https://en.wikipedia.org/wiki/Shebang_%28Unix%29) line that points to the version of Bash used in Nixpkgs.
<!-- this cannot be changed in practice, so there is no point pretending it's somehow generic -->
::: {.example #ex-writeShellScript}
# Usage of `writeShellScript`
```nix
writeShellScript "my-script"
''
echo "hi"
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-script";
text = ''
#! ${pkgs.runtimeShell}
echo "hi"
'';
executable = true;
}
```
### `writeShellScriptBin` {#trivial-builder-writeShellScriptBin}
Write a Bash script to a "bin" subdirectory of a directory in the Nix store.
`writeShellScriptBin` takes the following arguments:
`name` (String)
: The name used in the Nix store path and within the file generated under the store path.
`text` (String)
: The contents of the file.
The file's contents will be put into `/nix/store/<store path>/bin/<name>`.
The store path will include the the name, and it will be a directory.
This function is a combination of [](#trivial-builder-writeShellScript) and [](#trivial-builder-writeScriptBin).
::: {.example #ex-writeShellScriptBin}
# Usage of `writeShellScriptBin`
```nix
writeShellScriptBin "my-script"
''
echo "hi"
'';
```
:::
This is equivalent to:
```nix
writeTextFile {
name = "my-script";
text = ''
#! ${pkgs.runtimeShell}
echo "hi"
'';
executable = true;
destination = "bin/my-script"
}
```
## `concatTextFile`, `concatText`, `concatScript` {#trivial-builder-concatText}
These functions concatenate `files` to the Nix store in a single file. This is useful for configuration files structured in lines of text. `concatTextFile` takes an attribute set and expects two arguments, `name` and `files`. `name` corresponds to the name used in the Nix store path. `files` will be the files to be concatenated. You can also set `executable` to true to make this file have the executable bit set.
`concatText` and`concatScript` are simple wrappers over `concatTextFile`.
Here are a few examples:
```nix
# Writes my-file to /nix/store/<store path>
concatTextFile {
name = "my-file";
files = [ drv1 "${drv2}/path/to/file" ];
}
# See also the `concatText` helper function below.
# Writes executable my-file to /nix/store/<store path>/bin/my-file
concatTextFile {
name = "my-file";
files = [ drv1 "${drv2}/path/to/file" ];
executable = true;
destination = "/bin/my-file";
}
# Writes contents of files to /nix/store/<store path>
concatText "my-file" [ file1 file2 ]
# Writes contents of files to /nix/store/<store path>
concatScript "my-file" [ file1 file2 ]
```
## `writeShellApplication` {#trivial-builder-writeShellApplication}
`writeShellApplication` is similar to `writeShellScriptBin` and `writeScriptBin` but supports runtime dependencies with `runtimeInputs`.
Writes an executable shell script to `/nix/store/<store path>/bin/<name>` and checks its syntax with [`shellcheck`](https://github.com/koalaman/shellcheck) and the `bash`'s `-n` option.
Some basic Bash options are set by default (`errexit`, `nounset`, and `pipefail`), but can be overridden with `bashOptions`.
Extra arguments may be passed to `stdenv.mkDerivation` by setting `derivationArgs`; note that variables set in this manner will be set when the shell script is _built,_ not when it's run.
Runtime environment variables can be set with the `runtimeEnv` argument.
For example, the following shell application can refer to `curl` directly, rather than needing to write `${curl}/bin/curl`:
```nix
writeShellApplication {
name = "show-nixos-org";
runtimeInputs = [ curl w3m ];
text = ''
curl -s 'https://nixos.org' | w3m -dump -T text/html
'';
}
```
## `symlinkJoin` {#trivial-builder-symlinkJoin}
This can be used to put many derivations into the same directory structure. It works by creating a new derivation and adding symlinks to each of the paths listed. It expects two arguments, `name`, and `paths`. `name` is the name used in the Nix store path for the created derivation. `paths` is a list of paths that will be symlinked. These paths can be to Nix store derivations or any other subdirectory contained within.
Here is an example:
```nix
# adds symlinks of hello and stack to current build and prints "links added"
symlinkJoin { name = "myexample"; paths = [ pkgs.hello pkgs.stack ]; postBuild = "echo links added"; }
```
This creates a derivation with a directory structure like the following:
```
/nix/store/sglsr5g079a5235hy29da3mq3hv8sjmm-myexample
|-- bin
| |-- hello -> /nix/store/qy93dp4a3rqyn2mz63fbxjg228hffwyw-hello-2.10/bin/hello
| `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/bin/stack
`-- share
|-- bash-completion
| `-- completions
| `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/bash-completion/completions/stack
|-- fish
| `-- vendor_completions.d
| `-- stack.fish -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/fish/vendor_completions.d/stack.fish
...
```
## `writeReferencesToFile` {#trivial-builder-writeReferencesToFile}
Writes the closure of transitive dependencies to a file.
This produces the equivalent of `nix-store -q --requisites`.
For example,
```nix
writeReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
```
produces an output path `/nix/store/<hash>-runtime-deps` containing
```nix
/nix/store/<hash>-hello-2.10
/nix/store/<hash>-hi
/nix/store/<hash>-libidn2-2.3.0
/nix/store/<hash>-libunistring-0.9.10
/nix/store/<hash>-glibc-2.32-40
```
You can see that this includes `hi`, the original input path,
`hello`, which is a direct reference, but also
the other paths that are indirectly required to run `hello`.
## `writeDirectReferencesToFile` {#trivial-builder-writeDirectReferencesToFile}
Writes the set of references to the output file, that is, their immediate dependencies.
This produces the equivalent of `nix-store -q --references`.
For example,
```nix
writeDirectReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
```
produces an output path `/nix/store/<hash>-runtime-references` containing
```nix
/nix/store/<hash>-hello-2.10
```
but none of `hello`'s dependencies because those are not referenced directly
by `hi`'s output.

# Fetchers {#chap-pkgs-fetchers}
Building software with Nix often requires downloading source code and other files from the internet.
`nixpkgs` provides *fetchers* for different protocols and services. Fetchers are functions that simplify downloading files.
## Caveats {#chap-pkgs-fetchers-caveats}
Fetchers create [fixed output derivations](https://nixos.org/manual/nix/stable/#fixed-output-drvs) from downloaded files.
Nix can reuse the downloaded files via the hash of the resulting derivation.
The fact that the hash belongs to the Nix derivation output and not the file itself can lead to confusion.
For example, consider the following fetcher:
```nix
fetchurl {
url = "http://www.example.org/hello-1.0.tar.gz";
hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
};
```
A common mistake is to update a fetchers URL, or a version parameter, without updating the hash.
```nix
fetchurl {
url = "http://www.example.org/hello-1.1.tar.gz";
hash = "sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=";
};
```
**This will reuse the old contents**.
Remember to invalidate the hash argument, in this case by setting the `hash` attribute to an empty string.
```nix
fetchurl {
url = "http://www.example.org/hello-1.1.tar.gz";
hash = "";
};
```
Use the resulting error message to determine the correct hash.
```
error: hash mismatch in fixed-output derivation '/path/to/my.drv':
specified: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
got: sha256-lTeyxzJNQeMdu1IVdovNMtgn77jRIhSybLdMbTkf2Ww=
```
A similar problem arises while testing changes to a fetcher's implementation. If the output of the derivation already exists in the Nix store, test failures can go undetected. The [`invalidateFetcherByDrvHash`](#tester-invalidateFetcherByDrvHash) function helps prevent reusing cached derivations.
## `fetchurl` and `fetchzip` {#fetchurl}
Two basic fetchers are `fetchurl` and `fetchzip`. Both of these have two required arguments, a URL and a hash. The hash is typically `hash`, although many more hash algorithms are supported. Nixpkgs contributors are currently recommended to use `hash`. This hash will be used by Nix to identify your source. A typical usage of `fetchurl` is provided below.
```nix
{ stdenv, fetchurl }:
stdenv.mkDerivation {
name = "hello";
src = fetchurl {
url = "http://www.example.org/hello.tar.gz";
hash = "sha256-BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=";
};
}
```
The main difference between `fetchurl` and `fetchzip` is in how they store the contents. `fetchurl` will store the unaltered contents of the URL within the Nix store. `fetchzip` on the other hand, will decompress the archive for you, making files and directories directly accessible in the future. `fetchzip` can only be used with archives. Despite the name, `fetchzip` is not limited to .zip files and can also be used with any tarball.
## `fetchpatch` {#fetchpatch}
`fetchpatch` works very similarly to `fetchurl` with the same arguments expected. It expects patch files as a source and performs normalization on them before computing the checksum. For example, it will remove comments or other unstable parts that are sometimes added by version control systems and can change over time.
- `relative`: Similar to using `git-diff`'s `--relative` flag, only keep changes inside the specified directory, making paths relative to it.
- `stripLen`: Remove the first `stripLen` components of pathnames in the patch.
- `decode`: Pipe the downloaded data through this command before processing it as a patch.
- `extraPrefix`: Prefix pathnames by this string.
- `excludes`: Exclude files matching these patterns (applies after the above arguments).
- `includes`: Include only files matching these patterns (applies after the above arguments).
- `revert`: Revert the patch.
Note that because the checksum is computed after applying these effects, using or modifying these arguments will have no effect unless the `hash` argument is changed as well.
Most other fetchers return a directory rather than a single file.
## `fetchDebianPatch` {#fetchdebianpatch}
A wrapper around `fetchpatch`, which takes:
- `patch` and `hash`: the patch's filename,
and its hash after normalization by `fetchpatch` ;
- `pname`: the Debian source package's name ;
- `version`: the upstream version number ;
- `debianRevision`: the [Debian revision number] if applicable ;
- the `area` of the Debian archive: `main` (default), `contrib`, or `non-free`.
Here is an example of `fetchDebianPatch` in action:
```nix
{ lib
, fetchDebianPatch
, buildPythonPackage
}:
buildPythonPackage rec {
pname = "pysimplesoap";
version = "1.16.2";
src = ...;
patches = [
(fetchDebianPatch {
inherit pname version;
debianRevision = "5";
name = "Add-quotes-to-SOAPAction-header-in-SoapClient.patch";
hash = "sha256-xA8Wnrpr31H8wy3zHSNfezFNjUJt1HbSXn3qUMzeKc0=";
})
];
...
}
```
Patches are fetched from `sources.debian.org`, and so must come from a
package version that was uploaded to the Debian archive. Packages may
be removed from there once that specific version isn't in any suite
anymore (stable, testing, unstable, etc.), so maintainers should use
`copy-tarballs.pl` to archive the patch if it needs to be available
longer-term.
[Debian revision number]: https://www.debian.org/doc/debian-policy/ch-controlfields.html#version
## `fetchsvn` {#fetchsvn}
Used with Subversion. Expects `url` to a Subversion directory, `rev`, and `hash`.
## `fetchgit` {#fetchgit}
Used with Git. Expects `url` to a Git repo, `rev`, and `hash`. `rev` in this case can be full the git commit id (SHA1 hash) or a tag name like `refs/tags/v1.0`.
Additionally, the following optional arguments can be given: `fetchSubmodules = true` makes `fetchgit` also fetch the submodules of a repository. If `deepClone` is set to true, the entire repository is cloned as opposing to just creating a shallow clone. `deepClone = true` also implies `leaveDotGit = true` which means that the `.git` directory of the clone won't be removed after checkout.
If only parts of the repository are needed, `sparseCheckout` can be used. This will prevent git from fetching unnecessary blobs from server, see [git sparse-checkout](https://git-scm.com/docs/git-sparse-checkout) for more information:
```nix
{ stdenv, fetchgit }:
stdenv.mkDerivation {
name = "hello";
src = fetchgit {
url = "https://...";
sparseCheckout = [
"directory/to/be/included"
"another/directory"
];
hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
};
}
```
## `fetchfossil` {#fetchfossil}
Used with Fossil. Expects `url` to a Fossil archive, `rev`, and `hash`.
## `fetchcvs` {#fetchcvs}
Used with CVS. Expects `cvsRoot`, `tag`, and `hash`.
## `fetchhg` {#fetchhg}
Used with Mercurial. Expects `url`, `rev`, and `hash`.
A number of fetcher functions wrap part of `fetchurl` and `fetchzip`. They are mainly convenience functions intended for commonly used destinations of source code in Nixpkgs. These wrapper fetchers are listed below.
## `fetchFromGitea` {#fetchfromgitea}
`fetchFromGitea` expects five arguments. `domain` is the gitea server name. `owner` is a string corresponding to the Gitea user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every Gitea HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available but `hash` is currently preferred.
## `fetchFromGitHub` {#fetchfromgithub}
`fetchFromGitHub` expects four arguments. `owner` is a string corresponding to the GitHub user or organization that controls this repository. `repo` corresponds to the name of the software repository. These are located at the top of every GitHub HTML page as `owner`/`repo`. `rev` corresponds to the Git commit hash or tag (e.g `v1.0`) that will be downloaded from Git. Finally, `hash` corresponds to the hash of the extracted directory. Again, other hash algorithms are also available, but `hash` is currently preferred.
To use a different GitHub instance, use `githubBase` (defaults to `"github.com"`).
`fetchFromGitHub` uses `fetchzip` to download the source archive generated by GitHub for the specified revision. If `leaveDotGit`, `deepClone` or `fetchSubmodules` are set to `true`, `fetchFromGitHub` will use `fetchgit` instead. Refer to its section for documentation of these options.
## `fetchFromGitLab` {#fetchfromgitlab}
This is used with GitLab repositories. It behaves similarly to `fetchFromGitHub`, and expects `owner`, `repo`, `rev`, and `hash`.
To use a specific GitLab instance, use `domain` (defaults to `"gitlab.com"`).
## `fetchFromGitiles` {#fetchfromgitiles}
This is used with Gitiles repositories. The arguments expected are similar to `fetchgit`.
## `fetchFromBitbucket` {#fetchfrombitbucket}
This is used with BitBucket repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSavannah` {#fetchfromsavannah}
This is used with Savannah repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromRepoOrCz` {#fetchfromrepoorcz}
This is used with repo.or.cz repositories. The arguments expected are very similar to `fetchFromGitHub` above.
## `fetchFromSourcehut` {#fetchfromsourcehut}
This is used with sourcehut repositories. Similar to `fetchFromGitHub` above,
it expects `owner`, `repo`, `rev` and `hash`, but don't forget the tilde (~)
in front of the username! Expected arguments also include `vc` ("git" (default)
or "hg"), `domain` and `fetchSubmodules`.
If `fetchSubmodules` is `true`, `fetchFromSourcehut` uses `fetchgit`
or `fetchhg` with `fetchSubmodules` or `fetchSubrepos` set to `true`,
respectively. Otherwise, the fetcher uses `fetchzip`.
## `requireFile` {#requirefile}
`requireFile` allows requesting files that cannot be fetched automatically, but whose content is known.
This is a useful last-resort workaround for license restrictions that prohibit redistribution, or for downloads that are only accessible after authenticating interactively in a browser.
If the requested file is present in the Nix store, the resulting derivation will not be built, because its expected output is already available.
Otherwise, the builder will run, but fail with a message explaining to the user how to provide the file. The following code, for example:
```
requireFile {
name = "jdk-${version}_linux-x64_bin.tar.gz";
url = "https://www.oracle.com/java/technologies/javase-jdk11-downloads.html";
hash = "sha256-lL00+F7jjT71nlKJ7HRQuUQ7kkxVYlZh//5msD8sjeI=";
}
```
results in this error message:
```
***
Unfortunately, we cannot download file jdk-11.0.10_linux-x64_bin.tar.gz automatically.
Please go to https://www.oracle.com/java/technologies/javase-jdk11-downloads.html to download it yourself, and add it to the Nix store
using either
nix-store --add-fixed sha256 jdk-11.0.10_linux-x64_bin.tar.gz

# pkgs.appimageTools {#sec-pkgs-appimageTools}
`pkgs.appimageTools` is a set of functions for extracting and wrapping [AppImage](https://appimage.org/) files. They are meant to be used if traditional packaging from source is infeasible, or it would take too long. To quickly run an AppImage file, `pkgs.appimage-run` can be used as well.
::: {.warning}
The `appimageTools` API is unstable and may be subject to backwards-incompatible changes in the future.
:::
## AppImage formats {#ssec-pkgs-appimageTools-formats}
There are different formats for AppImages, see [the specification](https://github.com/AppImage/AppImageSpec/blob/74ad9ca2f94bf864a4a0dac1f369dd4f00bd1c28/draft.md#image-format) for details.
- Type 1 images are ISO 9660 files that are also ELF executables.
- Type 2 images are ELF executables with an appended filesystem.
They can be told apart with `file -k`:
```ShellSession
$ file -k type1.AppImage
type1.AppImage: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) ISO 9660 CD-ROM filesystem data 'AppImage' (Lepton 3.x), scale 0-0,

$ file -k type2.AppImage
type2.AppImage: ELF 64-bit LSB executable, x86-64, version 1 (SYSV) (Lepton 3.x), scale 232-60668, spot sensor temperature -4.187500, color scheme 15, show scale bar, calibration: offset -0.000000, slope 0.000000 (Lepton 2.x), scale 4111-45000, spot sensor temperature 412442.250000, color scheme 3, minimum point enabled, calibration: offset -75402534979642766821519867692934234112.000000, slope 5815371847733706829839455140374904832.000000, dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 2.6.18, BuildID[sha1]=79dcc4e55a61c293c5e19edbd8d65b202842579f, stripped\012- data
```
Note how the type 1 AppImage is described as an `ISO 9660 CD-ROM filesystem`, and the type 2 AppImage is not.
## Wrapping {#ssec-pkgs-appimageTools-wrapping}
Depending on the type of AppImage you're wrapping, you'll have to use `wrapType1` or `wrapType2`.
```nix
appimageTools.wrapType2 { # or wrapType1
name = "patchwork";
src = fetchurl {
url = "https://github.com/ssbc/patchwork/releases/download/v3.11.4/Patchwork-3.11.4-linux-x86_64.AppImage";
hash = "sha256-OqTitCeZ6xmWbqYTXp8sDrmVgTNjPZNW0hzUPW++mq4=";
};
extraPkgs = pkgs: with pkgs; [ ];
}
```
- `name` specifies the name of the resulting image.
- `src` specifies the AppImage file to extract.
- `extraPkgs` allows you to pass a function to include additional packages inside the FHS environment your AppImage is going to run in. There are a few ways to learn which dependencies an application needs:
- Looking through the extracted AppImage files, reading its scripts and running `patchelf` and `ldd` on its executables. This can also be done in `appimage-run`, by setting `APPIMAGE_DEBUG_EXEC=bash`.
- Running `strace -vfefile` on the wrapped executable, looking for libraries that can't be found.

# 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 {#sec-pkgs-binary-cache-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
```
```shellSession

# pkgs.dockerTools {#sec-pkgs-dockerTools}
`pkgs.dockerTools` is a set of functions for creating and manipulating Docker images according to the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#docker-image-specification-v120). Docker itself is not used to perform any of the operations done by these functions.
## buildImage {#ssec-pkgs-dockerTools-buildImage}
This function is analogous to the `docker build` command, in that it can be used to build a Docker-compatible repository tarball containing a single image with one or multiple layers. As such, the result is suitable for being loaded in Docker with `docker load`.
The parameters of `buildImage` with relative example values are described below:
[]{#ex-dockerTools-buildImage}
[]{#ex-dockerTools-buildImage-runAsRoot}
```nix
buildImage {
name = "redis";
tag = "latest";
fromImage = someBaseImage;
fromImageName = null;
fromImageTag = "latest";
copyToRoot = pkgs.buildEnv {
name = "image-root";
paths = [ pkgs.redis ];
pathsToLink = [ "/bin" ];
};
runAsRoot = ''
#!${pkgs.runtimeShell}
mkdir -p /data
'';
config = {
Cmd = [ "/bin/redis-server" ];
WorkingDir = "/data";
Volumes = { "/data" = { }; };
};
diskSize = 1024;
buildVMMemorySize = 512;
}
```
The above example will build a Docker image `redis/latest` from the given base image. Loading and running this image in Docker results in `redis-server` being started automatically.
- `name` specifies the name of the resulting image. This is the only required argument for `buildImage`.
- `tag` specifies the tag of the resulting image. By default it's `null`, which indicates that the nix output hash will be used as tag.
- `fromImage` is the repository tarball containing the base image. It must be a valid Docker image, such as exported by `docker save`. By default it's `null`, which can be seen as equivalent to `FROM scratch` of a `Dockerfile`.
- `fromImageName` can be used to further specify the base image within the repository, in case it contains multiple images. By default it's `null`, in which case `buildImage` will peek the first image available in the repository.
- `fromImageTag` can be used to further specify the tag of the base image within the repository, in case an image contains multiple tags. By default it's `null`, in which case `buildImage` will peek the first tag available for the base image.
- `copyToRoot` is a derivation that will be copied in the new layer of the resulting image. This can be similarly seen as `ADD contents/ /` in a `Dockerfile`. By default it's `null`.
- `runAsRoot` is a bash script that will run as root in an environment that overlays the existing layers of the base image with the new resulting layer, including the previously copied `contents` derivation. This can be similarly seen as `RUN ...` in a `Dockerfile`.
> **_NOTE:_** Using this parameter requires the `kvm` device to be available.
- `config` is used to specify the configuration of the containers that will be started off the built image in Docker. The available options are listed in the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#image-json-field-descriptions).
- `architecture` is _optional_ and used to specify the image architecture, this is useful for multi-architecture builds that don't need cross compiling. If not specified it will default to `hostPlatform`.
- `diskSize` is used to specify the disk size of the VM used to build the image in megabytes. By default it's 1024 MiB.
- `buildVMMemorySize` is used to specify the memory size of the VM to build the image in megabytes. By default it's 512 MiB.
After the new layer has been created, its closure (to which `contents`, `config` and `runAsRoot` contribute) will be copied in the layer itself. Only new dependencies that are not already in the existing layers will be copied.
At the end of the process, only one new single layer will be produced and added to the resulting image.
The resulting repository will only list the single image `image/tag`. In the case of [the `buildImage` example](#ex-dockerTools-buildImage), it would be `redis/latest`.
It is possible to inspect the arguments with which an image was built using its `buildArgs` attribute.
> **_NOTE:_** If you see errors similar to `getProtocolByName: does not exist (no such protocol name: tcp)` you may need to add `pkgs.iana-etc` to `contents`.
> **_NOTE:_** If you see errors similar to `Error_Protocol ("certificate has unknown CA",True,UnknownCa)` you may need to add `pkgs.cacert` to `contents`.
By default `buildImage` will use a static date of one second past the UNIX Epoch. This allows `buildImage` to produce binary reproducible images. When listing images with `docker images`, the newly created images will be listed like this:
```ShellSession
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello latest 08c791c7846e 48 years ago 25.2MB
```
You can break binary reproducibility but have a sorted, meaningful `CREATED` column by setting `created` to `now`.
```nix
pkgs.dockerTools.buildImage {
name = "hello";
tag = "latest";
created = "now";
copyToRoot = pkgs.buildEnv {
name = "image-root";
paths = [ pkgs.hello ];
pathsToLink = [ "/bin" ];
};
config.Cmd = [ "/bin/hello" ];
}
```
Now the Docker CLI will display a reasonable date and sort the images as expected:
```ShellSession
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hello latest de2bf4786de6 About a minute ago 25.2MB
```
However, the produced images will not be binary reproducible.
## buildLayeredImage {#ssec-pkgs-dockerTools-buildLayeredImage}
Create a Docker image with many of the store paths being on their own layer to improve sharing between images. The image is realized into the Nix store as a gzipped tarball. Depending on the intended usage, many users might prefer to use `streamLayeredImage` instead, which this function uses internally.
`name`
: The name of the resulting image.
`tag` _optional_
: Tag of the generated image.
*Default:* the output path's hash
`fromImage` _optional_
: The repository tarball containing the base image. It must be a valid Docker image, such as one exported by `docker save`.
*Default:* `null`, which can be seen as equivalent to `FROM scratch` of a `Dockerfile`.
`contents` _optional_
: Top-level paths in the container. Either a single derivation, or a list of derivations.
*Default:* `[]`
`config` _optional_
`architecture` is _optional_ and used to specify the image architecture, this is useful for multi-architecture builds that don't need cross compiling. If not specified it will default to `hostPlatform`.
: Run-time configuration of the container. A full list of the options available is in the [Docker Image Specification v1.2.0](https://github.com/moby/moby/blob/master/image/spec/v1.2.md#image-json-field-descriptions).
*Default:* `{}`
`created` _optional_
: Date and time the layers were created. Follows the same `now` exception supported by `buildImage`.
*Default:* `1970-01-01T00:00:01Z`
`maxLayers` _optional_
: Maximum number of layers to create.
*Default:* `100`
*Maximum:* `125`
`extraCommands` _optional_
: Shell commands to run while building the final layer, without access to most of the layer contents. Changes to this layer are "on top" of all the other layers, so can create additional directories and files.
`fakeRootCommands` _optional_
: Shell commands to run while creating the archive for the final layer in a fakeroot environment. Unlike `extraCommands`, you can run `chown` to change the owners of the files in the archive, changing fakeroot's state instead of the real filesystem. The latter would require privileges that the build user does not have. Static binaries do not interact with the fakeroot environment. By default all files in the archive will be owned by root.
`enableFakechroot` _optional_
: Whether to run in `fakeRootCommands` in `fakechroot`, making programs behave as though `/` is the root of the image being created, while files in the Nix store are available as usual. This allows scripts that perform installation in `/` to work as expected. Considering that `fakechroot` is implemented via the same mechanism as `fakeroot`, the same caveats apply.
*Default:* `false`
### Behavior of `contents` in the final image {#dockerTools-buildLayeredImage-arg-contents}
Each path directly listed in `contents` will have a symlink in the root of the image.
For example:
```nix
pkgs.dockerTools.buildLayeredImage {
name = "hello";
contents = [ pkgs.hello ];
}
```
will create symlinks for all the paths in the `hello` package:
```ShellSession
/bin/hello -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/bin/hello
/share/info/hello.info -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/share/info/hello.info
/share/locale/bg/LC_MESSAGES/hello.mo -> /nix/store/h1zb1padqbbb7jicsvkmrym3r6snphxg-hello-2.10/share/locale/bg/LC_MESSAGES/hello.mo
```
### Automatic inclusion of `config` references {#dockerTools-buildLayeredImage-arg-config}
The closure of `config` is automatically included in the closure of the final image.
This allows you to make very simple Docker images with very little code. This container will start up and run `hello`:
```nix
pkgs.dockerTools.buildLayeredImage {
name = "hello";
config.Cmd = [ "${pkgs.hello}/bin/hello" ];
}
```
### Adjusting `maxLayers` {#dockerTools-buildLayeredImage-arg-maxLayers}
Increasing the `maxLayers` increases the number of layers which have a chance to be shared between different images.
Modern Docker installations support up to 128 layers, but older versions support as few as 42.
If the produced image will not be extended by other Docker builds, it is safe to set `maxLayers` to `128`. However, it will be impossible to extend the image further.
The first (`maxLayers-2`) most "popular" paths will have their own individual layers, then layer \#`maxLayers-1` will contain all the remaining "unpopular" paths, and finally layer \#`maxLayers` will contain the Image configuration.
Docker's Layers are not inherently ordered, they are content-addressable and are not explicitly layered until they are composed in to an Image.
## streamLayeredImage {#ssec-pkgs-dockerTools-streamLayeredImage}
Builds a script which, when run, will stream an uncompressed tarball of a Docker image to stdout. The arguments to this function are as for `buildLayeredImage`. This method of constructing an image does not realize the image into the Nix store, so it saves on IO and disk/cache space, particularly with large images.
The image produced by running the output script can be piped directly into `docker load`, to load it into the local docker daemon:
```ShellSession
$(nix-build) | docker load
```
Alternatively, the image be piped via `gzip` into `skopeo`, e.g., to copy it into a registry:
```ShellSession
$(nix-build) | gzip --fast | skopeo copy docker-archive:/dev/stdin docker://some_docker_registry/myimage:tag
```
## pullImage {#ssec-pkgs-dockerTools-fetchFromRegistry}
This function is analogous to the `docker pull` command, in that it can be used to pull a Docker image from a Docker registry. By default [Docker Hub](https://hub.docker.com/) is used to pull images.
Its parameters are described in the example below:
```nix
pullImage {
imageName = "nixos/nix";
imageDigest =
"sha256:473a2b527958665554806aea24d0131bacec46d23af09fef4598eeab331850fa";
finalImageName = "nix";
finalImageTag = "2.11.1";
sha256 = "sha256-qvhj+Hlmviz+KEBVmsyPIzTB3QlVAFzwAY1zDPIBGxc=";
os = "linux";
arch = "x86_64";
}
```
- `imageName` specifies the name of the image to be downloaded, which can also include the registry namespace (e.g. `nixos`). This argument is required.
- `imageDigest` specifies the digest of the image to be downloaded. This argument is required.
- `finalImageName`, if specified, this is the name of the image to be created. Note it is never used to fetch the image since we prefer to rely on the immutable digest ID. By default it's equal to `imageName`.
- `finalImageTag`, if specified, this is the tag of the image to be created. Note it is never used to fetch the image since we prefer to rely on the immutable digest ID. By default it's `latest`.
- `sha256` is the checksum of the whole fetched image. This argument is required.
- `os`, if specified, is the operating system of the fetched image. By default it's `linux`.
- `arch`, if specified, is the cpu architecture of the fetched image. By default it's `x86_64`.
`nix-prefetch-docker` command can be used to get required image parameters:
```ShellSession
$ nix run nixpkgs.nix-prefetch-docker -c nix-prefetch-docker --image-name mysql --image-tag 5
```
Since a given `imageName` may transparently refer to a manifest list of images which support multiple architectures and/or operating systems, you can supply the `--os` and `--arch` arguments to specify exactly which image you want. By default it will match the OS and architecture of the host the command is run on.
```ShellSession
$ nix-prefetch-docker --image-name mysql --image-tag 5 --arch x86_64 --os linux
```
Desired image name and tag can be set using `--final-image-name` and `--final-image-tag` arguments:
```ShellSession
$ nix-prefetch-docker --image-name mysql --image-tag 5 --final-image-name eu.gcr.io/my-project/mysql --final-image-tag prod
```
## exportImage {#ssec-pkgs-dockerTools-exportImage}
This function is analogous to the `docker export` command, in that it can be used to flatten a Docker image that contains multiple layers. It is in fact the result of the merge of all the layers of the image. As such, the result is suitable for being imported in Docker with `docker import`.
> **_NOTE:_** Using this function requires the `kvm` device to be available.
The parameters of `exportImage` are the following:
```nix
exportImage {
fromImage = someLayeredImage;
fromImageName = null;
fromImageTag = null;
name = someLayeredImage.name;
}
```
The parameters relative to the base image have the same synopsis as described in [buildImage](#ssec-pkgs-dockerTools-buildImage), except that `fromImage` is the only required argument in this case.
The `name` argument is the name of the derivation output, which defaults to `fromImage.name`.
## Environment Helpers {#ssec-pkgs-dockerTools-helpers}
Some packages expect certain files to be available globally.
When building an image from scratch (i.e. without `fromImage`), these files are missing.
`pkgs.dockerTools` provides some helpers to set up an environment with the necessary files.
You can include them in `copyToRoot` like this:
```nix
buildImage {
name = "environment-example";
copyToRoot = with pkgs.dockerTools; [
usrBinEnv
binSh
caCertificates
fakeNss
];
}
```
### usrBinEnv {#sssec-pkgs-dockerTools-helpers-usrBinEnv}
This provides the `env` utility at `/usr/bin/env`.
### binSh {#sssec-pkgs-dockerTools-helpers-binSh}
This provides `bashInteractive` at `/bin/sh`.
### caCertificates {#sssec-pkgs-dockerTools-helpers-caCertificates}
This sets up `/etc/ssl/certs/ca-certificates.crt`.
### fakeNss {#sssec-pkgs-dockerTools-helpers-fakeNss}
Provides `/etc/passwd` and `/etc/group` that contain root and nobody.
Useful when packaging binaries that insist on using nss to look up
username/groups (like nginx).
### shadowSetup {#ssec-pkgs-dockerTools-shadowSetup}
This constant string is a helper for setting up the base files for managing users and groups, only if such files don't exist already. It is suitable for being used in a [`buildImage` `runAsRoot`](#ex-dockerTools-buildImage-runAsRoot) script for cases like in the example below:
```nix
buildImage {
name = "shadow-basic";
runAsRoot = ''
#!${pkgs.runtimeShell}
${pkgs.dockerTools.shadowSetup}
groupadd -r redis
useradd -r -g redis redis
mkdir /data
chown redis:redis /data
'';
}
```
Creating base files like `/etc/passwd` or `/etc/login.defs` is necessary for shadow-utils to manipulate users and groups.
## fakeNss {#ssec-pkgs-dockerTools-fakeNss}
If your primary goal is providing a basic skeleton for user lookups to work,
and/or a lesser privileged user, adding `pkgs.fakeNss` to
the container image root might be the better choice than a custom script
running `useradd` and friends.
It provides a `/etc/passwd` and `/etc/group`, containing `root` and `nobody`
users and groups.
It also provides a `/etc/nsswitch.conf`, configuring NSS host resolution to
first check `/etc/hosts`, before checking DNS, as the default in the absence of
a config file (`dns [!UNAVAIL=return] files`) is quite unexpected.
You can pair it with `binSh`, which provides `bin/sh` as a symlink
to `bashInteractive` (as `/bin/sh` is configured as a shell).
```nix
buildImage {
name = "shadow-basic";
copyToRoot = pkgs.buildEnv {
name = "image-root";
paths = [ binSh pkgs.fakeNss ];
pathsToLink = [ "/bin" "/etc" "/var" ];
};
}
```
## buildNixShellImage {#ssec-pkgs-dockerTools-buildNixShellImage}
Create a Docker image that sets up an environment similar to that of running `nix-shell` on a derivation.
When run in Docker, this environment somewhat resembles the Nix sandbox typically used by `nix-build`, with a major difference being that access to the internet is allowed.
It additionally also behaves like an interactive `nix-shell`, running things like `shellHook` and setting an interactive prompt.
If the derivation is fully buildable (i.e. `nix-build` can be used on it), running `buildDerivation` inside such a Docker image will build the derivation, with all its outputs being available in the correct `/nix/store` paths, pointed to by the respective environment variables like `$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 {#ssec-pkgs-dockerTools-buildNixShellImage-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 {#ssec-pkgs-dockerTools-buildNixShellImage-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

# Linux kernel {#sec-linux-kernel}
The Nix expressions to build the Linux kernel are in [`pkgs/os-specific/linux/kernel`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel).
The function that builds the kernel has an argument `kernelPatches` which should be a list of `{name, patch, extraConfig}` attribute sets, where `name` is the name of the patch (which is included in the kernels `meta.description` attribute), `patch` is the patch itself (possibly compressed), and `extraConfig` (optional) is a string specifying extra options to be concatenated to the kernel configuration file (`.config`).
The kernel derivation exports an attribute `features` specifying whether optional functionality is or isnt enabled. This is used in NixOS to implement kernel-specific behaviour. For instance, if the kernel has the `iwlwifi` feature (i.e., has built-in support for Intel wireless chipsets), then NixOS doesnt have to build the external `iwlwifi` package:
```nix
modulesTree = [kernel]
++ pkgs.lib.optional (!kernel.features ? iwlwifi) kernelPackages.iwlwifi
++ ...;
```
How to add a new (major) version of the Linux kernel to Nixpkgs:
1. Copy the old Nix expression (e.g., `linux-2.6.21.nix`) to the new one (e.g., `linux-2.6.22.nix`) and update it.
2. Add the new kernel to the `kernels` attribute set in `linux-kernels.nix` (e.g., create an attribute `kernel_2_6_22`).
3. Now were going to update the kernel configuration. First unpack the kernel. Then for each supported platform (`i686`, `x86_64`, `uml`) do the following:
1. Make a copy from the old config (e.g., `config-2.6.21-i686-smp`) to the new one (e.g., `config-2.6.22-i686-smp`).
2. Copy the config file for this platform (e.g., `config-2.6.22-i686-smp`) to `.config` in the kernel source tree.
3. Run `make oldconfig ARCH={i386,x86_64,um}` and answer all questions. (For the uml configuration, also add `SHELL=bash`.) Make sure to keep the configuration consistent between platforms (i.e., dont enable some feature on `i686` and disable it on `x86_64`).
4. If needed, you can also run `make menuconfig`:
```ShellSession
$ nix-env -f "<nixpkgs>" -iA ncurses
$ export NIX_CFLAGS_LINK=-lncurses
$ make menuconfig ARCH=arch
```
5. Copy `.config` over the new config file (e.g., `config-2.6.22-i686-smp`).
4. Test building the kernel: `nix-build -A linuxKernel.kernels.kernel_2_6_22`. If it compiles, ship it! For extra credit, try booting NixOS with it.
5. It may be that the new kernel requires updating the external kernel modules and kernel-dependent packages listed in the `linuxPackagesFor` function in `linux-kernels.nix` (such as the NVIDIA drivers, AUFS, etc.). If the updated packages arent backwards compatible with older kernels, you may need to keep the older versions around.

# darwin.linux-builder {#sec-darwin-builder}
`darwin.linux-builder` provides a way to bootstrap a Linux builder on a macOS machine.
This requires macOS version 12.4 or later.
The builder runs on host port 31022 by default.
You can change it by overriding `virtualisation.darwin-builder.hostPort`.
See the [example](#sec-darwin-builder-example-flake).
You will also need to be a trusted user for your Nix installation. In other
words, your `/etc/nix/nix.conf` should have something like:
```
extra-trusted-users = <your username goes here>
```
To launch the builder, run the following flake:
```ShellSession
$ nix run nixpkgs#darwin.linux-builder
```
That will prompt you to enter your `sudo` password:
```
+ sudo --reset-timestamp /nix/store/…-install-credentials.sh ./keys
Password:
```
… so that it can install a private key used to `ssh` into the build server.
After that the script will launch the virtual machine and automatically log you
in as the `builder` user:
```
<<< Welcome to NixOS 22.11.20220901.1bd8d11 (aarch64) - ttyAMA0 >>>
Run 'nixos-help' for the NixOS manual.
nixos login: builder (automatic login)
[builder@nixos:~]$
```
> Note: When you need to stop the VM, run `shutdown now` as the `builder` user.
To delegate builds to the remote builder, add the following options to your
`nix.conf` file:
```
# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
builders = ssh-ng://builder@linux-builder ${ARCH}-linux /etc/nix/builder_ed25519 ${MAX_JOBS} - - - c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
# Not strictly necessary, but this will reduce your disk utilization
builders-use-substitutes = true
```
To allow Nix to connect to a builder not running on port 22, you will also need to create a new file at `/etc/ssh/ssh_config.d/100-linux-builder.conf`:
```
Host linux-builder
Hostname localhost
HostKeyAlias linux-builder
Port 31022
```
… and then restart your Nix daemon to apply the change:
```ShellSession
$ sudo launchctl kickstart -k system/org.nixos.nix-daemon
```
## Example flake usage {#sec-darwin-builder-example-flake}

StandardOutPath = "/var/log/darwin-builder.log";
StandardErrorPath = "/var/log/darwin-builder.log";
};
};
}
];
};
};
};
}
```
## Reconfiguring the builder {#sec-darwin-builder-reconfiguring}
Initially you should not change the builder configuration else you will not be
able to use the binary cache. However, after you have the builder running locally
you may use it to build a modified builder with additional storage or memory.
To do this, you just need to set the `virtualisation.darwin-builder.*` parameters as
in the example below and rebuild.
```
darwin-builder = nixpkgs.lib.nixosSystem {
system = linuxSystem;
modules = [
"${nixpkgs}/nixos/modules/profiles/macos-builder.nix"
{
virtualisation.host.pkgs = pkgs;
virtualisation.darwin-builder.diskSize = 5120;
virtualisation.darwin-builder.memorySize = 1024;
virtualisation.darwin-builder.hostPort = 33022;
virtualisation.darwin-builder.workingDirectory = "/var/lib/darwin-builder";
}
];
```
You may make any other changes to your VM in this attribute set. For example,
you could enable Docker or X11 forwarding to your Darwin host.

# Testers {#chap-testers}
This chapter describes several testing builders which are available in the `testers` namespace.
## `hasPkgConfigModules` {#tester-hasPkgConfigModules}
<!-- Old anchor name so links still work -->
[]{#tester-hasPkgConfigModule}
Checks whether a package exposes a given list of `pkg-config` modules.
If the `moduleNames` argument is omitted, `hasPkgConfigModules` will
use `meta.pkgConfigModules`.
Example:
```nix
passthru.tests.pkg-config = testers.hasPkgConfigModules {
package = finalAttrs.finalPackage;
moduleNames = [ "libfoo" ];
};
```
If the package in question has `meta.pkgConfigModules` set, it is even simpler:
```nix
passthru.tests.pkg-config = testers.hasPkgConfigModules {
package = finalAttrs.finalPackage;
};
meta.pkgConfigModules = [ "libfoo" ];
```
## `testVersion` {#tester-testVersion}
Checks the command output contains the specified version
Although simplistic, this test assures that the main program
can run. While there's no substitute for a real test case,
it does catch dynamic linking errors and such. It also provides
some protection against accidentally building the wrong version,
for example when using an 'old' hash in a fixed-output derivation.
Examples:
```nix
passthru.tests.version = testers.testVersion { package = hello; };
passthru.tests.version = testers.testVersion {
package = seaweedfs;
command = "weed version";
};
passthru.tests.version = testers.testVersion {
package = key;
command = "KeY --help";
# Wrong '2.5' version in the code. Drop on next version.
version = "2.5";
};
passthru.tests.version = testers.testVersion {
package = ghr;
# The output needs to contain the 'version' string without any prefix or suffix.
version = "v${version}";
};
```
## `testBuildFailure` {#tester-testBuildFailure}
Make sure that a build does not succeed. This is useful for testing testers.
This returns a derivation with an override on the builder, with the following effects:
- Fail the build when the original builder succeeds
- Move `$out` to `$out/result`, if it exists (assuming `out` is the default output)
- Save the build log to `$out/testBuildFailure.log` (same)
Example:
```nix
runCommand "example" {
failed = testers.testBuildFailure (runCommand "fail" {} ''
echo ok-ish >$out
echo failing though
exit 3
'');
} ''
grep -F 'ok-ish' $failed/result
grep -F 'failing though' $failed/testBuildFailure.log
[[ 3 = $(cat $failed/testBuildFailure.exit) ]]
touch $out
'';
```
While `testBuildFailure` is designed to keep changes to the original builder's
environment to a minimum, some small changes are inevitable.
- The file `$TMPDIR/testBuildFailure.log` is present. It should not be deleted.
- `stdout` and `stderr` are a pipe instead of a tty. This could be improved.
- One or two extra processes are present in the sandbox during the original
builder's execution.
- The derivation and output hashes are different, but not unusual.
- The derivation includes a dependency on `buildPackages.bash` and
`expect-failure.sh`, which is built to include a transitive dependency on
`buildPackages.coreutils` and possibly more. These are not added to `PATH`
or any other environment variable, so they should be hard to observe.
## `testEqualContents` {#tester-equalContents}
Check that two paths have the same contents.
Example:
```nix
testers.testEqualContents {
assertion = "sed -e performs replacement";
expected = writeText "expected" ''
foo baz baz
'';
actual = runCommand "actual" {
# not really necessary for a package that's in stdenv
nativeBuildInputs = [ gnused ];
base = writeText "base" ''
foo bar baz
'';
} ''
sed -e 's/bar/baz/g' $base >$out
'';
}
```
## `testEqualDerivation` {#tester-testEqualDerivation}
Checks that two packages produce the exact same build instructions.
This can be used to make sure that a certain difference of configuration,
such as the presence of an overlay does not cause a cache miss.
When the derivations are equal, the return value is an empty file.
Otherwise, the build log explains the difference via `nix-diff`.
Example:
```nix
testers.testEqualDerivation
"The hello package must stay the same when enabling checks."
hello
(hello.overrideAttrs(o: { doCheck = true; }))
```
## `invalidateFetcherByDrvHash` {#tester-invalidateFetcherByDrvHash}
Use the derivation hash to invalidate the output via name, for testing.
Type: `(a@{ name, ... } -> Derivation) -> a -> Derivation`
Normally, fixed output derivations can and should be cached by their output
hash only, but for testing we want to re-fetch everytime the fetcher changes.
Changes to the fetcher become apparent in the drvPath, which is a hash of
how to fetch, rather than a fixed store path.
By inserting this hash into the name, we can make sure to re-run the fetcher
every time the fetcher changes.
This relies on the assumption that Nix isn't clever enough to reuse its
database of local store contents to optimize fetching.
You might notice that the "salted" name derives from the normal invocation,
not the final derivation. `invalidateFetcherByDrvHash` has to invoke the fetcher
function twice: once to get a derivation hash, and again to produce the final
fixed output derivation.
Example:
```nix
tests.fetchgit = testers.invalidateFetcherByDrvHash fetchgit {
name = "nix-source";
url = "https://github.com/NixOS/nix";
rev = "9d9dbe6ed05854e03811c361a3380e09183f4f4a";
hash = "sha256-7DszvbCNTjpzGRmpIVAWXk20P0/XTrWZ79KSOGLrUWY=";
};
```
## `runNixOSTest` {#tester-runNixOSTest}
A helper function that behaves exactly like the NixOS `runTest`, except it also assigns this Nixpkgs package set as the `pkgs` of the test and makes the `nixpkgs.*` options read-only.
If your test is part of the Nixpkgs repository, or if you need a more general entrypoint, see ["Calling a test" in the NixOS manual](https://nixos.org/manual/nixos/stable/index.html#sec-calling-nixos-tests).
Example:
```nix
pkgs.testers.runNixOSTest ({ lib, ... }: {
name = "hello";
nodes.machine = { pkgs, ... }: {
environment.systemPackages = [ pkgs.hello ];
};
testScript = ''
machine.succeed("hello")
'';
})
```
## `nixosTest` {#tester-nixosTest}
Run a NixOS VM network test using this evaluation of Nixpkgs.
NOTE: This function is primarily for external use. NixOS itself uses `make-test-python.nix` directly. Packages defined in Nixpkgs [reuse NixOS tests via `nixosTests`, plural](#ssec-nixos-tests-linking).
It is mostly equivalent to the function `import ./make-test-python.nix` from the
[NixOS manual](https://nixos.org/nixos/manual/index.html#sec-nixos-tests),
except that the current application of Nixpkgs (`pkgs`) will be used, instead of
letting NixOS invoke Nixpkgs anew.
If a test machine needs to set NixOS options under `nixpkgs`, it must set only the
`nixpkgs.pkgs` option.
### Parameter {#tester-nixosTest-parameter}
A [NixOS VM test network](https://nixos.org/nixos/manual/index.html#sec-nixos-tests), or path to it. Example:
```nix
{
name = "my-test";
nodes = {
machine1 = { lib, pkgs, nodes, ... }: {
environment.systemPackages = [ pkgs.hello ];
services.foo.enable = true;
};
# machine2 = ...;
};
testScript = ''
start_all()
machine1.wait_for_unit("foo.service")
machine1.succeed("hello | foo-send")
'';
}
```
### Result {#tester-nixosTest-result}
A derivation that runs the VM test.
Notable attributes:
* `nodes`: the evaluated NixOS configurations. Useful for debugging and exploring the configuration.
* `driverInteractive`: a script that launches an interactive Python session in the context of the `testScript`.

# Trivial builders {#chap-trivial-builders}
Nixpkgs provides a couple of functions that help with building derivations. The most important one, `stdenv.mkDerivation`, has already been documented above. The following functions wrap `stdenv.mkDerivation`, making it easier to use in certain cases.
## `runCommand` {#trivial-builder-runCommand}
`runCommand :: String -> AttrSet -> String -> Derivation`
`runCommand name drvAttrs buildCommand` returns a derivation that is built by running the specified shell commands.
`name :: String`
: The name that Nix will append to the store path in the same way that `stdenv.mkDerivation` uses its `name` attribute.
`drvAttr :: AttrSet`
: Attributes to pass to the underlying call to [`stdenv.mkDerivation`](#chap-stdenv).
`buildCommand :: String`
: Shell commands to run in the derivation builder.
::: {.note}
You have to create a file or directory `$out` for Nix to be able to run the builder successfully.
:::
::: {.example #ex-runcommand-simple}
# Invocation of `runCommand`
```nix
(import <nixpkgs> {}).runCommand "my-example" {} ''
echo My example command is running
mkdir $out
echo I can write data to the Nix store > $out/message
echo I can also run basic commands like:
echo ls
ls
echo whoami
whoami
echo date
date
''
```
:::
## `runCommandCC` {#trivial-builder-runCommandCC}
This works just like `runCommand`. The only difference is that it also provides a C compiler in `buildCommand`'s environment. To minimize your dependencies, you should only use this if you are sure you will need a C compiler as part of running your command.
## `runCommandLocal` {#trivial-builder-runCommandLocal}
Variant of `runCommand` that forces the derivation to be built locally, it is not substituted. This is intended for very cheap commands (<1s execution time). It saves on the network round-trip and can speed up a build.
::: {.note}
This sets [`allowSubstitutes` to `false`](https://nixos.org/nix/manual/#adv-attr-allowSubstitutes), so only use `runCommandLocal` if you are certain the user will always have a builder for the `system` of the derivation. This should be true for most trivial use cases (e.g., just copying some files to a different location or adding symlinks) because there the `system` is usually the same as `builtins.currentSystem`.
:::
## `writeTextFile`, `writeText`, `writeTextDir`, `writeScript`, `writeScriptBin` {#trivial-builder-writeText}
These functions write `text` to the Nix store. This is useful for creating scripts from Nix expressions. `writeTextFile` takes an attribute set and expects two arguments, `name` and `text`. `name` corresponds to the name used in the Nix store path. `text` will be the contents of the file. You can also set `executable` to true to make this file have the executable bit set.
Many more commands wrap `writeTextFile` including `writeText`, `writeTextDir`, `writeScript`, and `writeScriptBin`. These are convenience functions over `writeTextFile`.
Here are a few examples:
```nix
# Writes my-file to /nix/store/<store path>
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
}
# See also the `writeText` helper function below.
# Writes executable my-file to /nix/store/<store path>/bin/my-file
writeTextFile {
name = "my-file";
text = ''
Contents of File
'';
executable = true;
destination = "/bin/my-file";
}
# Writes contents of file to /nix/store/<store path>
writeText "my-file"
''
Contents of File
'';
# Writes contents of file to /nix/store/<store path>/share/my-file
writeTextDir "share/my-file"
''
Contents of File
'';
# Writes my-file to /nix/store/<store path> and makes executable
writeScript "my-file"
''
Contents of File
'';
# Writes my-file to /nix/store/<store path>/bin/my-file and makes executable.
writeScriptBin "my-file"
''
Contents of File
'';
# Writes my-file to /nix/store/<store path> and makes executable.
writeShellScript "my-file"
''
Contents of File
'';
# Writes my-file to /nix/store/<store path>/bin/my-file and makes executable.
writeShellScriptBin "my-file"
''
Contents of File
'';
```
## `concatTextFile`, `concatText`, `concatScript` {#trivial-builder-concatText}
These functions concatenate `files` to the Nix store in a single file. This is useful for configuration files structured in lines of text. `concatTextFile` takes an attribute set and expects two arguments, `name` and `files`. `name` corresponds to the name used in the Nix store path. `files` will be the files to be concatenated. You can also set `executable` to true to make this file have the executable bit set.
`concatText` and`concatScript` are simple wrappers over `concatTextFile`.
Here are a few examples:
```nix
# Writes my-file to /nix/store/<store path>
concatTextFile {
name = "my-file";
files = [ drv1 "${drv2}/path/to/file" ];
}
# See also the `concatText` helper function below.
# Writes executable my-file to /nix/store/<store path>/bin/my-file
concatTextFile {
name = "my-file";
files = [ drv1 "${drv2}/path/to/file" ];
executable = true;
destination = "/bin/my-file";
}
# Writes contents of files to /nix/store/<store path>
concatText "my-file" [ file1 file2 ]
# Writes contents of files to /nix/store/<store path>
concatScript "my-file" [ file1 file2 ]
```
## `writeShellApplication` {#trivial-builder-writeShellApplication}
This can be used to easily produce a shell script that has some dependencies (`runtimeInputs`). It automatically sets the `PATH` of the script to contain all of the listed inputs, sets some sanity shellopts (`errexit`, `nounset`, `pipefail`), and checks the resulting script with [`shellcheck`](https://github.com/koalaman/shellcheck).
For example, look at the following code:
```nix
writeShellApplication {
name = "show-nixos-org";
runtimeInputs = [ curl w3m ];
text = ''
curl -s 'https://nixos.org' | w3m -dump -T text/html
'';
}
```
Unlike with normal `writeShellScriptBin`, there is no need to manually write out `${curl}/bin/curl`, setting the PATH
was handled by `writeShellApplication`. Moreover, the script is being checked with `shellcheck` for more strict
validation.
## `symlinkJoin` {#trivial-builder-symlinkJoin}
This can be used to put many derivations into the same directory structure. It works by creating a new derivation and adding symlinks to each of the paths listed. It expects two arguments, `name`, and `paths`. `name` is the name used in the Nix store path for the created derivation. `paths` is a list of paths that will be symlinked. These paths can be to Nix store derivations or any other subdirectory contained within.
Here is an example:
```nix
# adds symlinks of hello and stack to current build and prints "links added"
symlinkJoin { name = "myexample"; paths = [ pkgs.hello pkgs.stack ]; postBuild = "echo links added"; }
```
This creates a derivation with a directory structure like the following:
```
/nix/store/sglsr5g079a5235hy29da3mq3hv8sjmm-myexample
|-- bin
| |-- hello -> /nix/store/qy93dp4a3rqyn2mz63fbxjg228hffwyw-hello-2.10/bin/hello
| `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/bin/stack
`-- share
|-- bash-completion
| `-- completions
| `-- stack -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/bash-completion/completions/stack
|-- fish
| `-- vendor_completions.d
| `-- stack.fish -> /nix/store/6lzdpxshx78281vy056lbk553ijsdr44-stack-2.1.3.1/share/fish/vendor_completions.d/stack.fish
...
```
## `writeReferencesToFile` {#trivial-builder-writeReferencesToFile}
Writes the closure of transitive dependencies to a file.
This produces the equivalent of `nix-store -q --requisites`.
For example,
```nix
writeReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
```
produces an output path `/nix/store/<hash>-runtime-deps` containing
```nix
/nix/store/<hash>-hello-2.10
/nix/store/<hash>-hi
/nix/store/<hash>-libidn2-2.3.0
/nix/store/<hash>-libunistring-0.9.10
/nix/store/<hash>-glibc-2.32-40
```
You can see that this includes `hi`, the original input path,
`hello`, which is a direct reference, but also
the other paths that are indirectly required to run `hello`.
## `writeDirectReferencesToFile` {#trivial-builder-writeDirectReferencesToFile}
Writes the set of references to the output file, that is, their immediate dependencies.
This produces the equivalent of `nix-store -q --references`.
For example,
```nix
writeDirectReferencesToFile (writeScriptBin "hi" ''${hello}/bin/hello'')
```
produces an output path `/nix/store/<hash>-runtime-references` containing
```nix
/nix/store/<hash>-hello-2.10
```
but none of `hello`'s dependencies because those are not referenced directly
by `hi`'s output.

# File sets {#sec-fileset}
The [`lib.fileset`](#sec-functions-library-fileset) library allows you to work with _file sets_.
A file set is a mathematical set of local files that can be added to the Nix store for use in Nix derivations.
File sets are easy and safe to use, providing obvious and composable semantics with good error messages to prevent mistakes.
These sections apply to the entire library.
See the [function reference](#sec-functions-library-fileset) for function-specific documentation.
The file set library is currently somewhat limited but is being expanded to include more functions over time.
## Implicit coercion from paths to file sets {#sec-fileset-path-coercion}
All functions accepting file sets as arguments can also accept [paths](https://nixos.org/manual/nix/stable/language/values.html#type-path) as arguments.
Such path arguments are implicitly coerced to file sets containing all files under that path:
- A path to a file turns into a file set containing that single file.
- A path to a directory turns into a file set containing all files _recursively_ in that directory.
If the path points to a non-existent location, an error is thrown.
::: {.note}
Just like in Git, file sets cannot represent empty directories.
Because of this, a path to a directory that contains no files (recursively) will turn into a file set containing no files.
:::
:::{.note}
File set coercion does _not_ add any of the files under the coerced paths to the store.
Only the [`toSource`](#function-library-lib.fileset.toSource) function adds files to the Nix store, and only those files contained in the `fileset` argument.
This is in contrast to using [paths in string interpolation](https://nixos.org/manual/nix/stable/language/values.html#type-path), which does add the entire referenced path to the store.
:::
### Example {#sec-fileset-path-coercion-example}
Assume we are in a local directory with a file hierarchy like this:
```
├─ a/
│ ├─ x (file)
│ └─ b/
  └─ y (file)
└─ c/
  └─ d/
```
Here's a listing of which files get included when different path expressions get coerced to file sets:
- `./.` as a file set contains both `a/x` and `a/b/y` (`c/` does not contain any files and is therefore omitted).
- `./a` as a file set contains both `a/x` and `a/b/y`.
- `./a/x` as a file set contains only `a/x`.
- `./a/b` as a file set contains only `a/b/y`.
- `./c` as a file set is empty, since neither `c` nor `c/d` contain any files.

The `installShellCompletion` function takes one or more paths to shell completion files. By default it will autodetect the shell type from the completion file extension, but you may also specify it by passing one of `--bash`, `--fish`, or `--zsh`. These flags apply to all paths listed after them (up until another shell flag is given). Each path may also have a custom installation name provided by providing a flag `--name NAME` before the path. If this flag is not provided, zsh completions will be renamed automatically such that `foobar.zsh` becomes `_foobar`. A root name may be provided for all paths using the flag `--cmd NAME`; this synthesizes the appropriate name depending on the shell (e.g. `--cmd foo` will synthesize the name `foo.bash` for bash and `_foo` for zsh). The path may also be a fifo or named fd (such as produced by `<(cmd)`), in which case the shell and name must be provided.

The function `buildDartApplication` builds Dart applications managed with pub.

The hooks can be used in other derivations, if needed. The phases can also be overridden to do something different from installing binaries.
It fetches its Dart dependencies automatically through `pub2nix`, and (through a series of hooks) builds and installs the executables specified in the pubspec file. The hooks can be used in other derivations, if needed. The phases can also be overridden to do something different from installing binaries.
If you are packaging a Flutter desktop application, use [`buildFlutterApplication`](#ssec-dart-flutter) instead.
`vendorHash`: is the hash of the output of the dependency fetcher derivation. To obtain it, simply set it to `lib.fakeHash` (or omit it) and run the build ([more details here](#sec-source-hashes)).
`pubspecLock` is the parsed pubspec.lock file. pub2nix uses this to download required packages.
This can be converted to JSON from YAML with something like `yq . pubspec.lock`, and then read by Nix.
If the upstream source is missing a `pubspec.lock` file, you'll have to vendor one and specify it using `pubspecLockFile`. If it is needed, one will be generated for you and printed when attempting to build the derivation.
Alternatively, `autoPubspecLock` can be used instead, and set to a path to a regular `pubspec.lock` file. This relies on import-from-derivation, and is not permitted in Nixpkgs, but can be useful at other times.
::: {.warning}
When using `autoPubspecLock` with a local source directory, make sure to use a
concatenation operator (e.g. `autoPubspecLock = src + "/pubspec.lock";`), and
not string interpolation.
String interpolation will copy your entire source directory to the Nix store and
use its store path, meaning that unrelated changes to your source tree will
cause the generated `pubspec.lock` derivation to rebuild!
:::
If the package has Git package dependencies, the hashes must be provided in the `gitHashes` set. If a hash is missing, an error message prompting you to add it will be shown.
The `dart` commands run can be overridden through `pubGetScript` and `dartCompileCommand`, you can also add flags using `dartCompileFlags` or `dartJitFlags`.
Dart supports multiple [outputs types](https://dart.dev/tools/dart-compile#types-of-output), you can choose between them using `dartOutputType` (defaults to `exe`). If you want to override the binaries path or the source path they come from, you can use `dartEntryPoints`. Outputs that require a runtime will automatically be wrapped with the relevant runtime (`dartaotruntime` for `aot-snapshot`, `dart run` for `jit-snapshot` and `kernel`, `node` for `js`), this can be overridden through `dartRuntimeCommand`.

### Patching dependencies {#ssec-dart-applications-patching-dependencies}
Some Dart packages require patches or build environment changes. Package derivations can be customised with the `customSourceBuilders` argument.
A collection of such customisations can be found in Nixpkgs, in the `development/compilers/dart/package-source-builders` directory.
This allows fixes for packages to be shared between all applications that use them. It is strongly recommended to add to this collection instead of including fixes in your application derivation itself.
### Running executables from dev_dependencies {#ssec-dart-applications-build-tools}
Many Dart applications require executables from the `dev_dependencies` section in `pubspec.yaml` to be run before building them.
This can be done in `preBuild`, in one of two ways:
1. Packaging the tool with `buildDartApplication`, adding it to Nixpkgs, and running it like any other application
2. Running the tool from the package cache
Of these methods, the first is recommended when using a tool that does not need
to be of a specific version.
For the second method, the `packageRun` function from the `dartConfigHook` can be used.
This is an alternative to `dart run` that does not rely on Pub.
e.g., for `build_runner`:
```bash
packageRun build_runner build
```
Do _not_ use `dart run <package_name>`, as this will attempt to download dependencies with Pub.
### Usage with nix-shell {#ssec-dart-applications-nix-shell}
#### Using dependencies from the Nix store {#ssec-dart-applications-nix-shell-deps}
As `buildDartApplication` provides dependencies instead of `pub get`, Dart needs to be explicitly told where to find them.
Run the following commands in the source directory to configure Dart appropriately.
Do not use `pub` after doing so; it will download the dependencies itself and overwrite these changes.

mkdir -p .dart_tool && cp --no-preserve=all "$packageConfig" .dart_tool/package_config.json

## Flutter applications {#ssec-dart-flutter}

The deps.json file must always be provided when packaging in Nixpkgs. It will be generated and printed if the derivation is attempted to be built without one. Alternatively, `autoDepsList` may be set to `true` when outside of Nixpkgs, as it relies on import-from-derivation.
A `pubspec.lock` file must be available. See the [Dart documentation](#ssec-dart-applications) for more details.

#### Entering the shell {#ssec-dart-flutter-nix-shell-enter}
By default, dependencies for only the `targetFlutterPlatform` are available in the
build environment. This is useful for keeping closures small, but be problematic
during development. It's common, for example, to build Web apps for Linux during
development to take advantage of native features such as stateful hot reload.

## Generating and updating NuGet dependencies {#generating-and-updating-nuget-dependencies}

the upstream repository and you are inside it.
```bash
$ dotnet restore --packages out

Restored /home/lychee/Celeste64/Celeste64.csproj (in 1.21 sec).

Next, use `nuget-to-nix` tool provided in nixpkgs to generate a lockfile to `deps.nix` from
the packages inside the `out` directory.
```bash
$ nuget-to-nix out > deps.nix
```
Which `nuget-to-nix` will generate an output similar to below
```
{ fetchNuGet }: [
(fetchNuGet { pname = "FosterFramework"; version = "0.1.15-alpha"; sha256 = "0pzsdfbsfx28xfqljcwy100xhbs6wyx0z1d5qxgmv3l60di9xkll"; })

]
```
Finally, you move the `deps.nix` file to the appropriate location to be used by `nugetDeps`, then you're all set!
If you ever need to update the dependencies of a package, you instead do
* `nix-build -A package.fetch-deps` to generate the update script for `package`
* Run `./result deps.nix` to regenerate the lockfile to `deps.nix`, keep in mind if a location isn't provided, it will write to a temporary path instead
* Finally, move the file where needed and look at its contents to confirm it has updated the dependencies.

[Emscripten](https://github.com/kripken/emscripten): An LLVM-to-JavaScript Compiler
This section of the manual covers how to use `emscripten` in nixpkgs.
If you want to work with `emcc`, `emconfigure` and `emmake` as you are used to from Ubuntu and similar distributions,
Minimal requirements:
* nix
* nixpkgs
Modes of use of `emscripten`:
* **Imperative usage** (on the command line):
If you want to work with `emcc`, `emconfigure` and `emmake` as you are used to from Ubuntu and similar distributions you can use these commands:
* `nix-env -f "<nixpkgs>" -iA emscripten`
* `nix-shell -p emscripten`
* **Declarative usage**:
This mode is far more power full since this makes use of `nix` for dependency management of emscripten libraries and targets by using the `mkDerivation` which is implemented by `pkgs.emscriptenStdenv` and `pkgs.buildEmscriptenPackage`. The source for the packages is in `pkgs/top-level/emscripten-packages.nix` and the abstraction behind it in `pkgs/development/em-modules/generic/default.nix`. From the root of the nixpkgs repository:
* build and install all packages:
* `nix-env -iA emscriptenPackages`
* dev-shell for zlib implementation hacking:
* `nix-shell -A emscriptenPackages.zlib`
## Imperative usage {#imperative-usage}
```console
nix-shell -p emscripten
```
A few things to note:
* `export EMCC_DEBUG=2` is nice for debugging
* `~/.emscripten`, the build artifact cache sometimes creates issues and needs to be removed from time to time
* The build artifact cache in `~/.emscripten` sometimes creates issues and needs to be removed from time to time
## Declarative usage {#declarative-usage}
## Examples {#declarative-usage}
Let's see two different examples from `pkgs/top-level/emscripten-packages.nix`:
* `pkgs.zlib.override`
* `pkgs.buildEmscriptenPackage`
Both are interesting concepts.
A special requirement of the `pkgs.buildEmscriptenPackage` is the `doCheck = true`.
This means each Emscripten package requires that a [`checkPhase`](#ssec-check-phase) is implemented.
A special requirement of the `pkgs.buildEmscriptenPackage` is the `doCheck = true` is a default meaning that each emscriptenPackage requires a `checkPhase` implemented.
* Use `export EMCC_DEBUG=2` from within a phase to get more detailed debug output what is going wrong.
* The cache at `~/.emscripten` requires to set `HOME=$TMPDIR` in individual phases.
This makes compilation slower but also more deterministic.
* Use `export EMCC_DEBUG=2` from within a emscriptenPackage's `phase` to get more detailed debug output what is going wrong.
* ~/.emscripten cache is requiring us to set `HOME=$TMPDIR` in individual phases. This makes compilation slower but also makes it more deterministic.

## Building Go modules with `buildGoModule` {#ssec-language-go}
The function `buildGoModule` builds Go programs managed with Go modules. It builds a [Go Modules](https://github.com/golang/go/wiki/Modules) through a two phase build:
The function `buildGoModule` builds Go programs managed with Go modules. It builds [Go Modules](https://github.com/golang/go/wiki/Modules) through a two phase build:
- An intermediate fetcher derivation. This derivation will be used to fetch all of the dependencies of the Go module.
- An intermediate fetcher derivation called `goModules`. This derivation will be used to fetch all the dependencies of the Go module.
- A final derivation will use the output of the intermediate derivation to build the binaries and produce the final output.
### Attributes of `buildGoModule` {#buildgomodule-parameters}
The `buildGoModule` function accepts the following parameters in addition to the [attributes accepted by both Go builders](#ssec-go-common-attributes):
- `vendorHash`: is the hash of the output of the intermediate fetcher derivation (the dependencies of the Go modules).
`vendorHash` can be set to `null`.
In that case, rather than fetching the dependencies, the dependencies already vendored in the `vendor` directory of the source repo will be used.
To avoid updating this field when dependencies change, run `go mod vendor` in your source repo and set `vendorHash = null;`.
You can read more about [vendoring in the Go documentation](https://go.dev/ref/mod#vendoring).
To obtain the actual hash, set `vendorHash = lib.fakeHash;` and run the build ([more details here](#sec-source-hashes)).
- `proxyVendor`: If `true`, the intermediate fetcher downloads dependencies from the
[Go module proxy](https://go.dev/ref/mod#module-proxy) (using `go mod download`) instead of vendoring them. The resulting
[module cache](https://go.dev/ref/mod#module-cache) is then passed to the final derivation.
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-dependent `vendorHash` checksums.
Defaults to `false`.
- `modPostBuild`: Shell commands to run after the build of the goModules executes `go mod vendor`, and before calculating fixed output derivation's `vendorHash`.
Note that if you change this attribute, you need to update `vendorHash` attribute.
- `modRoot`: The root directory of the Go module that contains the `go.mod` file.
Defaults to `./`, which is the root of `src`.
### Example for `buildGoModule` {#ex-buildGoModule}
In the following is an example expression using `buildGoModule`, the following arguments are of special significance to the function:
- `vendorHash`: is the hash of the output of the intermediate fetcher derivation.
`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.
To avoid updating this field when dependencies change, run `go mod vendor` in your source repo and set `vendorHash = null;`
To obtain the actual hash, set `vendorHash = lib.fakeSha256;` and run the build ([more details here](#sec-source-hashes)).
- `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-dependent `vendorHash` checksums.
- `modPostBuild`: Shell commands to run after the build of the goModules executes `go mod vendor`, and before calculating fixed output derivation's `vendorHash` (or `vendorSha256`). Note that if you change this attribute, you need to update `vendorHash` (or `vendorSha256`) attribute.

Specified as a string or list of strings. Causes the builder to skip building child packages that match any of the provided values.
### `CGO_ENABLED` {#var-go-CGO_ENABLED}
When set to `0`, the [cgo](https://pkg.go.dev/cmd/cgo) command is disabled. As consequence, the build
program can't link against C libraries anymore, and the resulting binary is statically linked.
When building with CGO enabled, Go will likely link some packages from the Go standard library against C libraries,
even when the target code does not explicitly call into C dependencies. With `CGO_ENABLED = 0;`, Go
will always use the Go native implementation of these internal packages. For reference see
[net](https://pkg.go.dev/net#hdr-Name_Resolution) and [os/user](https://pkg.go.dev/os/user#pkg-overview) packages.
Notice that the decision whether these packages should use native Go implementation or not can also be controlled
on a per package level using build tags (`tags`). In case CGO is disabled, these tags have no additional effect.
When a Go program depends on C libraries, place those dependencies in `buildInputs`:
```nix
buildInputs = [
libvirt
libxml2
];
```
`CGO_ENABLED` defaults to `1`.
### `enableParallelBuilding` {#var-go-enableParallelBuilding}
Whether builds and tests should run in parallel.
Defaults to `true`.
### `allowGoReference` {#var-go-allowGoReference}
Whether the build result should be allowed to contain references to the Go tool chain. This might be needed for programs that are coupled with the compiler, but shouldn't be set without a good reason.
Defaults to `false`
## Controlling the Go environment {#ssec-go-environment}
The Go build can be further tweaked by setting environment variables. In most cases, this isn't needed. Possible values can be found in the [Go documentation of accepted environment variables](https://pkg.go.dev/cmd/go#hdr-Environment_variables). Notice that some of these flags are set by the builder itself and should not be set explicitly. If in doubt, grep the implementation of the builder.
## Skipping tests {#ssec-skip-go-tests}
`buildGoModule` runs tests by default. Failing tests can be disabled using the `checkFlags` parameter.
This is done with the [`-skip` or `-run`](https://pkg.go.dev/cmd/go#hdr-Testing_flags) flags of the `go test` command.
For example, only a selection of tests could be run with:
```nix
# -run and -skip accept regular expressions
checkFlags = [
"-run=^Test(Simple|Fast)$"
];
```
If a larger amount of tests should be skipped, the following pattern can be used:
```nix
checkFlags =
let
# Skip tests that require network access
skippedTests = [
"TestNetwork"
"TestDatabase/with_mysql" # exclude only the subtest
"TestIntegration"
];
in
[ "-skip=^${builtins.concatStringsSep "$|^" skippedTests}$" ];
```
To disable tests altogether, set `doCheck = false;`.
`buildGoPackage` does not execute tests by default.

# Idris2 {#sec-idris2}
In addition to exposing the Idris2 compiler itself, Nixpkgs exposes an `idris2Packages.buildIdris` helper to make it a bit more ergonomic to build Idris2 executables or libraries.
The `buildIdris` function takes an attribute set that defines at a minimum the `src` and `ipkgName` of the package to be built and any `idrisLibraries` required to build it. The `src` is the same source you're familiar with and the `ipkgName` must be the name of the `ipkg` file for the project (omitting the `.ipkg` extension). The `idrisLibraries` is a list of other library derivations created with `buildIdris`. You can optionally specify other derivation properties as needed but sensible defaults for `configurePhase`, `buildPhase`, and `installPhase` are provided.
Importantly, `buildIdris` does not create a single derivation but rather an attribute set with two properties: `executable` and `library`. The `executable` property is a derivation and the `library` property is a function that will return a derivation for the library with or without source code included. Source code need not be included unless you are aiming to use IDE or LSP features that are able to jump to definitions within an editor.
A simple example of a fully packaged library would be the [`LSP-lib`](https://github.com/idris-community/LSP-lib) found in the `idris-community` GitHub organization.
```nix
{ fetchFromGitHub, idris2Packages }:
let lspLibPkg = idris2Packages.buildIdris {
ipkgName = "lsp-lib";
src = fetchFromGitHub {
owner = "idris-community";
repo = "LSP-lib";
rev = "main";
hash = "sha256-EvSyMCVyiy9jDZMkXQmtwwMoLaem1GsKVFqSGNNHHmY=";
};
idrisLibraries = [ ];
};
in lspLibPkg.library
```
The above results in a derivation with the installed library results (with sourcecode).
A slightly more involved example of a fully packaged executable would be the [`idris2-lsp`](https://github.com/idris-community/idris2-lsp) which is an Idris2 language server that uses the `LSP-lib` found above.
```nix
{ callPackage, fetchFromGitHub, idris2Packages }:
# Assuming the previous example lives in `lsp-lib.nix`:
let lspLib = callPackage ./lsp-lib.nix { };
lspPkg = idris2Packages.buildIdris {
ipkgName = "idris2-lsp";
src = fetchFromGitHub {
owner = "idris-community";
repo = "idris2-lsp";
rev = "main";
hash = "sha256-vQTzEltkx7uelDtXOHc6QRWZ4cSlhhm5ziOqWA+aujk=";
};
idrisLibraries = [(idris2Packages.idris2Api { }) (lspLib { })];
};
in lspPkg.executable
```
The above uses the default value of `withSource = false` for both of the two required Idris libraries that the `idris2-lsp` executable depends on. `idris2Api` in the above derivation comes built in with `idris2Packages`. This library exposes many of the otherwise internal APIs of the Idris2 compiler.

# Julia {#language-julia}
## Introduction {#julia-introduction}
Nixpkgs includes Julia as the `julia` derivation.
You can get specific versions by looking at the other `julia*` top-level derivations available.
For example, `julia_19` corresponds to Julia 1.9.
We also provide the current stable version as `julia-stable`, and an LTS version as `julia-lts`.
Occasionally, a Julia version has been too difficult to build from source in Nixpkgs and has been fetched prebuilt instead.
These Julia versions are differentiated with the `*-bin` suffix; for example, `julia-stable-bin`.
## julia.withPackages {#julia-withpackage}
The basic Julia derivations only provide the built-in packages that come with the distribution.
You can build Julia environments with additional packages using the `julia.withPackages` command.
This function accepts a list of strings representing Julia package names.
For example, you can build a Julia environment with the `Plots` package as follows.
```nix
julia.withPackages ["Plots"]
```
Arguments can be passed using `.override`.
For example:
```nix
(julia.withPackages.override {
precompile = false; # Turn off precompilation
}) ["Plots"]
```
Here's a nice way to run a Julia environment with a shell one-liner:
```sh
nix-shell -p 'julia.withPackages ["Plots"]' --run julia
```
### Arguments {#julia-withpackage-arguments}
* `precompile`: Whether to run `Pkg.precompile()` on the generated environment.
This will make package imports faster, but may fail in some cases.
For example, there is an upstream issue with `Gtk.jl` that prevents precompilation from working in the Nix build sandbox, because the precompiled code tries to access a display.
Packages like this will work fine if you build with `precompile=false`, and then precompile as needed once your environment starts.
Defaults: `true`
* `extraLibs`: Extra library dependencies that will be placed on the `LD_LIBRARY_PATH` for Julia.
Should not be needed as we try to obtain library dependencies automatically using Julia's artifacts system.
* `makeWrapperArgs`: Extra arguments to pass to the `makeWrapper` call which we use to wrap the Julia binary.
* `setDefaultDepot`: Whether to automatically prepend `$HOME/.julia` to the `JULIA_DEPOT_PATH`.
This is useful because Julia expects a writable depot path as the first entry, which the one we build in Nixpkgs is not.
If there's no writable depot, then Julia will show a warning and be unable to save command history logs etc.
Default: `true`
* `packageOverrides`: Allows you to override packages by name by passing an alternative source.
For example, you can use a custom version of the `LanguageServer` package by passing `packageOverrides = { "LanguageServer" = fetchFromGitHub {...}; }`.
* `augmentedRegistry`: Allows you to change the registry from which Julia packages are drawn.
This normally points at a special augmented version of the Julia [General packages registry](https://github.com/JuliaRegistries/General).
If you want to use a bleeding-edge version to pick up the latest package updates, you can plug in a later revision than the one in Nixpkgs.

# Nim {#nim}
## Overview {#nim-overview}
The Nim compiler, a builder function, and some packaged libraries are available
in Nixpkgs. Until now each compiler release has been effectively backwards
compatible so only the latest version is available.
## Nim program packages in Nixpkgs {#nim-program-packages-in-nixpkgs}
Nim programs can be built using `nimPackages.buildNimPackage`. In the
case of packages not containing exported library code the attribute
`nimBinOnly` should be set to `true`.
The Nim compiler and a builder function is available.
Nim programs are built using `buildNimPackage` and a lockfile containing Nim dependencies.
The following example shows a Nim program that depends only on Nim libraries:
```nix
{ lib, nimPackages, fetchFromGitHub }:
{ lib, buildNimPackage, fetchFromGitHub }:
nimPackages.buildNimPackage (finalAttrs: {
buildNimPackage { } (finalAttrs: {
pname = "ttop";
version = "1.0.1";
nimBinOnly = true;
version = "1.2.7";
src = fetchFromGitHub {
owner = "inv2004";
repo = "ttop";
rev = "v${finalAttrs.version}";
hash = "sha256-x4Uczksh6p3XX/IMrOFtBxIleVHdAPX9e8n32VAUTC4=";
hash = "sha256-oPdaUqh6eN1X5kAYVvevOndkB/xnQng9QVLX9bu5P5E=";
};
buildInputs = with nimPackages; [ asciigraph illwill parsetoml zippy ];
lockFile = ./lock.json;
})
```
## Nim library packages in Nixpkgs {#nim-library-packages-in-nixpkgs}
Nim libraries can also be built using `nimPackages.buildNimPackage`, but
often the product of a fetcher is sufficient to satisfy a dependency.
The `fetchgit`, `fetchFromGitHub`, and `fetchNimble` functions yield an
output that can be discovered during the `configurePhase` of `buildNimPackage`.
Nim library packages are listed in
[pkgs/top-level/nim-packages.nix](https://github.com/NixOS/nixpkgs/blob/master/pkgs/top-level/nim-packages.nix) and implemented at
[pkgs/development/nim-packages](https://github.com/NixOS/nixpkgs/tree/master/pkgs/development/nim-packages).
The following example shows a Nim library that propagates a dependency on a
non-Nim package:
```nix
{ lib, buildNimPackage, fetchNimble, SDL2 }:
buildNimPackage (finalAttrs: {
pname = "sdl2";
version = "2.0.4";
src = fetchNimble {
inherit (finalAttrs) pname version;
hash = "sha256-Vtcj8goI4zZPQs2TbFoBFlcR5UqDtOldaXSH/+/xULk=";
};
propagatedBuildInputs = [ SDL2 ];
nimFlags = [
"-d:NimblePkgVersion=${finalAttrs.version}"
];
})
```
## `buildNimPackage` parameters {#buildnimpackage-parameters}
All parameters from `stdenv.mkDerivation` function are still supported. The
following are specific to `buildNimPackage`:

@@ -77,6 +41,85 @@ following are specific to `buildNimPackage`:
Use this to specify defines with arguments in the form of `-d:${name}=${value}`.
* `nimDoc` ? false`: Build and install HTML documentation.
* `buildInputs` ? []: The packages listed here will be searched for `*.nimble`
files which are used to populate the Nim library path. Otherwise the standard
behavior is in effect.
## Lockfiles {#nim-lockfiles}
Nim lockfiles are created with the `nim_lk` utility.
Run `nim_lk` with the source directory as an argument and it will print a lockfile to stdout.
```sh
$ cd nixpkgs
$ nix build -f . ttop.src
$ nix run -f . nim_lk ./result | jq --sort-keys > pkgs/by-name/tt/ttop/lock.json
```
## Overriding Nim packages {#nim-overrides}
The `buildNimPackage` function generates flags and additional build dependencies from the `lockFile` parameter passed to `buildNimPackage`. Using [`overrideAttrs`](#sec-pkg-overrideAttrs) on the final package will apply after this has already been generated, so this can't be used to override the `lockFile` in a package built with `buildNimPackage`. To be able to override parameters before flags and build dependencies are generated from the `lockFile`, use `overrideNimAttrs` instead with the same syntax as `overrideAttrs`:
```nix
pkgs.nitter.overrideNimAttrs {
# using a different source which has different dependencies from the standard package
src = pkgs.fetchFromGithub { /* … */ };
# new lock file generated from the source
lockFile = ./custom-lock.json;
}
```
## Lockfile dependency overrides {#nim-lock-overrides}
The `buildNimPackage` function matches the libraries specified by `lockFile` to attrset of override functions that are then applied to the package derivation.
The default overrides are maintained as the top-level `nimOverrides` attrset at `pkgs/top-level/nim-overrides.nix`.
For example, to propagate a dependency on SDL2 for lockfiles that select the Nim `sdl2` library, an overlay is added to the set in the `nim-overrides.nix` file:
```nix
{ lib
/* … */
, SDL2
/* … */
}:
{
/* … */
sdl2 =
lockAttrs:
finalAttrs:
{ buildInputs ? [ ], ... }:
{
buildInputs = buildInputs ++ [ SDL2 ];
};
/* … */
}
```
The annotations in the `nim-overrides.nix` set are functions that take three arguments and return a new attrset to be overlayed on the package being built.
- lockAttrs: the attrset for this library from within a lockfile. This can be used to implement library version constraints, such as marking libraries as broken or insecure.
- finalAttrs: the final attrset passed by `buildNimPackage` to `stdenv.mkDerivation`.
- prevAttrs: the attrset produced by initial arguments to `buildNimPackage` and any preceding lockfile overlays.
### Overriding an Nim library override {#nim-lock-overrides-overrides}
The `nimOverrides` attrset makes it possible to modify overrides in a few different ways.
Override a package internal to its definition:
```nix
{ lib, buildNimPackage, nimOverrides, libressl }:
let
buildNimPackage' = buildNimPackage.override {

Writing Nix expressions for Qt libraries and applications is largely similar as for other C++ software.
This section assumes some knowledge of the latter.
The major caveat with Qt applications is that Qt uses a plugin system to load additional modules at runtime,
from a list of well-known locations. In Nixpkgs, we patch QtCore to instead use an environment variable,
and wrap Qt applications to set it to the right paths. This effectively makes the runtime dependencies
pure and explicit at build-time, at the cost of introducing an extra indirection.

It is important to import Qt modules directly, that is: `qtbase`, `qtdeclarative`, etc. *Do not* import Qt package sets such as `qt5` because the Qt versions of dependencies may not be coherent, causing build and runtime failures.
Any Qt package should include `wrapQtAppsHook` in `nativeBuildInputs`, or explicitly set `dontWrapQtApps` to bypass generating the wrappers.
Additionally all Qt packages must include `wrapQtAppsHook` in `nativeBuildInputs`, or you must explicitly set `dontWrapQtApps`.

In the Nixpkgs tree, Ruby packages can be found throughout, depending on what they do, and are called from the main package set. Ruby gems, however are separate sets, and there's one default set for each interpreter (currently MRI only).
There are two main approaches for using Ruby with gems. One is to use a specifically locked `Gemfile` for an application that has very strict dependencies. The other is to depend on the common gems, which we'll explain further down, and rely on them being updated regularly.
The interpreters have common attributes, namely `gems`, and `withPackages`. So you can refer to `ruby.gems.nokogiri`, or `ruby_2_7.gems.nokogiri` to get the Nokogiri gem already compiled and ready to use.

## Using `git bisect` on the Rust compiler {#using-git-bisect-on-the-rust-compiler}
Sometimes an upgrade of the Rust compiler (`rustc`) will break a
downstream package. In these situations, being able to `git bisect`
the `rustc` version history to find the offending commit is quite
useful. Nixpkgs makes it easy to do this.
First, roll back your nixpkgs to a commit in which its `rustc` used
*the most recent one which doesn't have the problem.* You'll need
to do this because of `rustc`'s extremely aggressive
version-pinning.
Next, add the following overlay, updating the Rust version to the
one in your rolled-back nixpkgs, and replacing `/git/scratch/rust`
with the path into which you have `git clone`d the `rustc` git
repository:
```nix
(final: prev: /*lib.optionalAttrs prev.stdenv.targetPlatform.isAarch64*/ {
rust_1_72 =
lib.updateManyAttrsByPath [{
path = [ "packages" "stable" ];
update = old: old.overrideScope(final: prev: {
rustc-unwrapped = prev.rustc-unwrapped.overrideAttrs (_: {
src = lib.cleanSource /git/scratch/rust;
# do *not* put passthru.isReleaseTarball=true here
});
});
}]
prev.rust_1_72;
})
```
If the problem you're troubleshooting only manifests when
cross-compiling you can uncomment the `lib.optionalAttrs` in the
example above, and replace `isAarch64` with the target that is
having problems. This will speed up your bisect quite a bit, since
the host compiler won't need to be rebuilt.
Now, you can start a `git bisect` in the directory where you checked
out the `rustc` source code. It is recommended to select the
endpoint commits by searching backwards from `origin/master` for the
*commits which added the release notes for the versions in
question.* If you set the endpoints to commits on the release
branches (i.e. the release tags), git-bisect will often get confused
by the complex merge-commit structures it will need to traverse.
The command loop you'll want to use for bisecting looks like this:
```bash
git bisect {good,bad} # depending on result of last build
git submodule update --init
CARGO_NET_OFFLINE=false cargo vendor \
--sync ./src/tools/cargo/Cargo.toml \
--sync ./src/tools/rust-analyzer/Cargo.toml \
--sync ./compiler/rustc_codegen_cranelift/Cargo.toml \
--sync ./src/bootstrap/Cargo.toml
nix-build $NIXPKGS -A package-broken-by-rust-changes
```
The `git submodule update --init` and `cargo vendor` commands above
require network access, so they can't be performed from within the
`rustc` derivation, unfortunately.

Since release 15.09 there is a new TeX Live packaging that lives entirely under attribute `texlive`.
## User's guide (experimental new interface) {#sec-language-texlive-user-guide-experimental}
Release 23.11 ships with a new interface that will eventually replace `texlive.combine`.
- For basic usage, use some of the prebuilt environments available at the top level, such as `texliveBasic`, `texliveSmall`. For the full list of prebuilt environments, inspect `texlive.schemes`.
- Packages cannot be used directly but must be assembled in an environment. To create or add packages to an environment, use
```nix
texliveSmall.withPackages (ps: with ps; [ collection-langkorean algorithms cm-super ])
```
The function `withPackages` can be called multiple times to add more packages.
- **Note.** Within Nixpkgs, packages should only use prebuilt environments as inputs, such as `texliveSmall` or `texliveInfraOnly`, and should not depend directly on `texlive`. Further dependencies should be added by calling `withPackages`. This is to ensure that there is a consistent and simple way to override the inputs.
- `texlive.withPackages` uses the same logic as `buildEnv`. Only parts of a package are installed in an environment: its 'runtime' files (`tex` output), binaries (`out` output), and support files (`tlpkg` output). Moreover, man and info pages are assembled into separate `man` and `info` outputs. To add only the TeX files of a package, or its documentation (`texdoc` output), just specify the outputs:
```nix
texlive.withPackages (ps: with ps; [
texdoc # recommended package to navigate the documentation
perlPackages.LaTeXML.tex # tex files of LaTeXML, omit binaries
cm-super
cm-super.texdoc # documentation of cm-super
])
```
- All packages distributed by TeX Live, which contains most of CTAN, are available and can be found under `texlive.pkgs`:
```ShellSession
$ nix repl
nix-repl> :l <nixpkgs>
nix-repl> texlive.pkgs.[TAB]
```
Note that the packages in `texlive.pkgs` are only provided for search purposes and must not be used directly.
- **Experimental and subject to change without notice:** to add the documentation for all packages in the environment, use
```nix
texliveSmall.__overrideTeXConfig { withDocs = true; }
```
This can be applied before or after calling `withPackages`.
The function currently support the parameters `withDocs`, `withSources`, and `requireTeXPackages`.

- Note that the wrapper assumes that the result has a chance to be useful. For example, the core executables should be present, as well as some core data files. The supported way of ensuring this is by including some scheme, for example `scheme-basic`, into the combination.
- TeX Live packages are also available under `texlive.pkgs` as derivations with outputs `out`, `tex`, `texdoc`, `texsource`, `tlpkg`, `man`, `info`. They cannot be installed outside of `texlive.combine` but are available for other uses. To repackage a font, for instance, use
```nix
stdenvNoCC.mkDerivation rec {
src = texlive.pkgs.iwona;
inherit (src) pname version;
installPhase = ''
runHook preInstall
install -Dm644 fonts/opentype/nowacki/iwona/*.otf -t $out/share/fonts/opentype
runHook postInstall
'';
}
```
See `biber`, `iwona` for complete examples.
## Custom packages {#sec-language-texlive-custom-packages}
You may find that you need to use an external TeX package. A derivation for such package has to provide the contents of the "texmf" directory in its output and provide the appropriate `tlType` attribute (one of `"run"`, `"bin"`, `"doc"`, `"source"`). Dependencies on other TeX packages can be listed in the attribute `tlDeps`.
You may find that you need to use an external TeX package. A derivation for such package has to provide the contents of the "texmf" directory in its `"tex"` output, according to the [TeX Directory Structure](https://tug.ctan.org/tds/tds.html). Dependencies on other TeX packages can be listed in the attribute `tlDeps`.
Such derivation must then be listed in the attribute `pkgs` of an attribute set passed to `texlive.combine`, for instance by passing `extraPkgs = { pkgs = [ custom_package ]; };`. Within Nixpkgs, `pkgs` should be part of the derivation itself, allowing users to call `texlive.combine { inherit (texlive) scheme-small; inherit some_tex_package; }`.
The functions `texlive.combine` and `texlive.withPackages` recognise the following outputs:
Here is a (very verbose) example where the attribute `pkgs` is attached to the derivation itself, which requires creating a fixed point. See also the packages `auctex`, `eukleides`, `mftrace` for more examples.
- `"out"`: contents are linked in the TeX Live environment, and binaries in the `$out/bin` folder are wrapped;
- `"tex"`: linked in `$TEXMFDIST`; files should follow the TDS (for instance `$tex/tex/latex/foiltex/foiltex.cls`);
- `"texdoc"`, `"texsource"`: ignored by default, treated as `"tex"`;
- `"tlpkg"`: linked in `$TEXMFROOT/tlpkg`;
- `"man"`, `"info"`, ...: the other outputs are combined into separate outputs.
When using `pkgFilter`, `texlive.combine` will assign `tlType` respectively `"bin"`, `"run"`, `"doc"`, `"source"`, `"tlpkg"` to the above outputs.

## LuaLaTeX font cache {#sec-language-texlive-lualatex-font-cache}
The font cache for LuaLaTeX is written to `$HOME`.
Therefore, it is necessary to set `$HOME` to a writable path, e.g. [before using LuaLaTeX in nix derivations](https://github.com/NixOS/nixpkgs/issues/180639):
```nix
runCommandNoCC "lualatex-hello-world" {
buildInputs = [ texliveFull ];
} ''
mkdir $out
echo '\documentclass{article} \begin{document} Hello world \end{document}' > main.tex
env HOME=$(mktemp -d) lualatex -interaction=nonstopmode -output-format=pdf -output-directory=$out ./main.tex
''
```
Additionally, [the cache of a user can diverge from the nix store](https://github.com/NixOS/nixpkgs/issues/278718).
To resolve font issues that might follow, the cache can be removed by the user:
```ShellSession
luaotfload-tool --cache=erase --flush-lookups --force
```

# darwin.linux-builder {#sec-darwin-builder}
`darwin.linux-builder` provides a way to bootstrap a Linux remote builder on a macOS machine.
This requires macOS version 12.4 or later.
The remote builder runs on host port 31022 by default.
You can change it by overriding `virtualisation.darwin-builder.hostPort`.
See the [example](#sec-darwin-builder-example-flake).
You will also need to be a trusted user for your Nix installation. In other
words, your `/etc/nix/nix.conf` should have something like:
```
extra-trusted-users = <your username goes here>
```
To launch the remote builder, run the following flake:
```ShellSession
$ nix run nixpkgs#darwin.linux-builder
```
That will prompt you to enter your `sudo` password:
```
+ sudo --reset-timestamp /nix/store/…-install-credentials.sh ./keys
Password:
```
… so that it can install a private key used to `ssh` into the build server.
After that the script will launch the virtual machine and automatically log you
in as the `builder` user:
```
<<< Welcome to NixOS 22.11.20220901.1bd8d11 (aarch64) - ttyAMA0 >>>
Run 'nixos-help' for the NixOS manual.
nixos login: builder (automatic login)
[builder@nixos:~]$
```
> Note: When you need to stop the VM, run `shutdown now` as the `builder` user.
To delegate builds to the remote builder, add the following options to your
`nix.conf` file:
```
# - Replace ${ARCH} with either aarch64 or x86_64 to match your host machine
# - Replace ${MAX_JOBS} with the maximum number of builds (pick 4 if you're not sure)
builders = ssh-ng://builder@linux-builder ${ARCH}-linux /etc/nix/builder_ed25519 ${MAX_JOBS} - - - c3NoLWVkMjU1MTkgQUFBQUMzTnphQzFsWkRJMU5URTVBQUFBSUpCV2N4Yi9CbGFxdDFhdU90RStGOFFVV3JVb3RpQzVxQkorVXVFV2RWQ2Igcm9vdEBuaXhvcwo=
# Not strictly necessary, but this will reduce your disk utilization
builders-use-substitutes = true
```
To allow Nix to connect to a remote builder not running on port 22, you will also need to create a new file at `/etc/ssh/ssh_config.d/100-linux-builder.conf`:
```
Host linux-builder
Hostname localhost
HostKeyAlias linux-builder
Port 31022
```
… and then restart your Nix daemon to apply the change:
```ShellSession
$ sudo launchctl kickstart -k system/org.nixos.nix-daemon
```

## Reconfiguring the remote builder {#sec-darwin-builder-reconfiguring}
Initially you should not change the remote builder configuration else you will not be
able to use the binary cache. However, after you have the remote builder running locally
you may use it to build a modified remote builder with additional storage or memory.
To do this, you just need to set the `virtualisation.darwin-builder.*` parameters as
in the example below and rebuild.
```
darwin-builder = nixpkgs.lib.nixosSystem {
system = linuxSystem;
modules = [
"${nixpkgs}/nixos/modules/profiles/macos-builder.nix"
{
virtualisation.host.pkgs = pkgs;
virtualisation.darwin-builder.diskSize = 5120;
virtualisation.darwin-builder.memorySize = 1024;
virtualisation.darwin-builder.hostPort = 33022;
virtualisation.darwin-builder.workingDirectory = "/var/lib/darwin-builder";
}
];
```
You may make any other changes to your VM in this attribute set. For example,
you could enable Docker or X11 forwarding to your Darwin host.
## Troubleshooting the generated configuration {#sec-darwin-builder-troubleshoot}
The `linux-builder` package exposes the attributes `nixosConfig` and `nixosOptions` that allow you to inspect the generated NixOS configuration in the `nix repl`. For example:
```
$ nix repl --file ~/src/nixpkgs --argstr system aarch64-darwin
nix-repl> darwin.linux-builder.nixosConfig.nix.package
«derivation /nix/store/...-nix-2.17.0.drv»
nix-repl> :p darwin.linux-builder.nixosOptions.virtualisation.memorySize.definitionsWithLocations
[ { file = "/home/user/src/nixpkgs/nixos/modules/profiles/macos-builder.nix"; value = 3072; } ]
```
