# Contributing to Nix
|
||||
|
||||
Welcome and thank you for your interest in contributing to Nix!
|
||||
We appreciate your support.
|
||||
|
||||
Reading and following these guidelines will help us make the contribution process easy and effective for everyone involved.
|
||||
|
||||
|
||||
## Report a bug
|
||||
|
||||
1. Check on the [GitHub issue tracker](https://github.com/NixOS/nix/issues) if your bug was already reported.
|
||||
|
||||
2. If you were not able to find the bug or feature [open a new issue](https://github.com/NixOS/nix/issues/new/choose)
|
||||
|
||||
3. The issue templates will guide you in specifying your issue.
|
||||
The more complete the information you provide, the more likely it can be found by others and the more useful it is in the future.
|
||||
Make sure reported bugs can be reproduced easily.
|
||||
|
||||
4. Once submitted, do not expect issues to be picked up or solved right away.
|
||||
The only way to ensure this, is to [work on the issue yourself](#making-changes-to-nix).
|
||||
|
||||
## Report a security vulnerability
|
||||
|
||||
Check out the [security policy](https://github.com/NixOS/nix/security/policy).
|
||||
|
||||
## Making changes to Nix
|
||||
|
||||
1. Check for [pull requests](https://github.com/NixOS/nix/pulls) that might already cover the contribution you are about to make.
|
||||
There are many open pull requests that might already do what you intent to work on.
|
||||
You can use [labels](https://github.com/NixOS/nix/labels) to filter for relevant topics.
|
||||
|
||||
2. Search for related issues that cover what you're going to work on. It could help to mention there that you will work on the issue.
|
||||
|
||||
3. Check the [Nix reference manual](https://nixos.org/manual/nix/unstable/contributing/hacking.html) for information on building Nix and running its tests.
|
||||
|
||||
For contributions to the command line interface, please check the [CLI guidelines](https://nixos.org/manual/nix/unstable/contributing/cli-guideline.html).
|
||||
|
||||
4. Make your changes!
|
||||
|
||||
5. [Create a pull request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request) for your changes.
|
||||
* [Mark the pull request as draft](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/changing-the-stage-of-a-pull-request) if you're not done with the changes.
|
||||
* Make sure to have [a clean history of commits on your branch by using rebase](https://www.digitalocean.com/community/tutorials/how-to-rebase-and-update-a-pull-request).
|
||||
* Link related issues in your pull request to inform interested parties and future contributors about your change.
|
||||
If your pull request closes one or multiple issues, note that in the description using `Closes: #<number>`, as it will then happen automatically when your change is merged.
|
||||
|
||||
6. Do not expect your pull request to be reviewed immediately.
|
||||
Nix maintainers follow a [structured process for reviews and design decisions](https://github.com/NixOS/nix/tree/master/maintainers#project-board-protocol), which may or may not prioritise your work.
|
||||
|
||||
7. If you need additional feedback or help to getting pull request into shape, ask other contributors using [@mentions](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax#mentioning-people-and-teams).
|
||||
|
||||
## Making changes to the Nix manual
|
||||
|
||||
The Nix reference manual is hosted on https://nixos.org/manual/nix.
|
||||
The underlying source files are located in [`doc/manual/src`](./doc/manual/src).
|
||||
For small changes you can [use GitHub to edit these files](https://docs.github.com/en/repositories/working-with-files/managing-files/editing-files)
|
||||
For larger changes see the [Nix reference manual](https://nixos.org/manual/nix/unstable/contributing/hacking.html).
|
||||
|
||||
## Getting help
|
||||
|
||||
Whenever you're stuck or do not know how to proceed, you can always ask for help.
|
||||
The appropriate channels to do so can be found on the [NixOS Community](https://nixos.org/community/) page.

Most Nix commands interpret the following environment variables:

- [`IN_NIX_SHELL`]{#env-IN_NIX_SHELL}\
|
||||
- <span id="env-IN_NIX_SHELL">[`IN_NIX_SHELL`](#env-IN_NIX_SHELL)</span>\
|
||||
Indicator that tells if the current environment was set up by
|
||||
`nix-shell`. It can have the values `pure` or `impure`.
|
||||
|
||||
- [`NIX_PATH`]{#env-NIX_PATH}\

expressions using [paths](@docroot@/language/values.md#type-path)
|
||||
enclosed in angle brackets (i.e., `<path>`),

e.g. `/home/eelco/Dev:/etc/nixos`. It can be extended using the

If `NIX_PATH` is not set at all, Nix will fall back to the following list in [impure](@docroot@/command-ref/conf-file.md#conf-pure-eval) and [unrestricted](@docroot@/command-ref/conf-file.md#conf-restrict-eval) evaluation mode:

|
||||
|
||||
## Description
|
||||
|
||||
The install operation creates a new user environment, based on the
|
||||
current generation of the active profile, to which a set of store paths
|
||||
described by *args* is added. The arguments *args* map to store paths in
|
||||
a number of possible ways:
|
||||
|
||||
- By default, *args* is a set of derivation names denoting derivations
|
||||
in the active Nix expression. These are realised, and the resulting
|
||||
output paths are installed. Currently installed derivations with a
|
||||
name equal to the name of a derivation being added are removed
|
||||
unless the option `--preserve-installed` is specified.
|
||||
|
||||
If there are multiple derivations matching a name in *args* that
|
||||
have the same name (e.g., `gcc-3.3.6` and `gcc-4.1.1`), then the
|
||||
derivation with the highest *priority* is used. A derivation can
|
||||
define a priority by declaring the `meta.priority` attribute. This
|
||||
attribute should be a number, with a higher value denoting a lower
|
||||
priority. The default priority is `0`.
|
||||
|
||||
If there are multiple matching derivations with the same priority,
|
||||
then the derivation with the highest version will be installed.
|
||||
|
||||
You can force the installation of multiple derivations with the same
|
||||
name by being specific about the versions. For instance, `nix-env -i
|
||||
gcc-3.3.6 gcc-4.1.1` will install both version of GCC (and will
|
||||
probably cause a user environment conflict\!).
|
||||
|
||||
- If `--attr` (`-A`) is specified, the arguments are *attribute
|
||||
paths* that select attributes from the top-level Nix
|
||||
expression. This is faster than using derivation names and
|
||||
unambiguous. To find out the attribute paths of available
|
||||
packages, use `nix-env -qaP`.
|
||||
|
||||
- If `--from-profile` *path* is given, *args* is a set of names
|
||||
denoting installed store paths in the profile *path*. This is an
|
||||
easy way to copy user environment elements from one profile to
|
||||
another.
|
||||
|
||||
- If `--from-expression` is given, *args* are Nix
|
||||
[functions](../language/constructs.md#functions)
|
||||
that are called with the active Nix expression as their single
|
||||
argument. The derivations returned by those function calls are
|
||||
installed. This allows derivations to be specified in an
|
||||
unambiguous way, which is necessary if there are multiple
|
||||
derivations with the same name.
|
||||
|
||||
- If *args* are [store derivation]s, then these are
|
||||
[realised](nix-store.md#operation---realise), and the resulting output paths
|
||||
are installed.
|
||||
|
||||
[store derivation]: ../glossary.md#gloss-store-derivation
|
||||
|
||||
- If *args* are store paths that are not store derivations, then these
|
||||
are [realised](nix-store.md#operation---realise) and installed.
|
||||
|
||||
- By default all outputs are installed for each derivation. That can
|
||||
be reduced by setting `meta.outputsToInstall`.
|
||||
|
||||
## Flags
|
||||
|
||||
- `--prebuilt-only` / `-b`\
|
||||
Use only derivations for which a substitute is registered, i.e.,
|
||||
there is a pre-built binary available that can be downloaded in lieu
|
||||
of building the derivation. Thus, no packages will be built from
|
||||
source.
|
||||
|
||||
- `--preserve-installed`; `-P`\
|
||||
Do not remove derivations with a name matching one of the
|
||||
derivations being installed. Usually, trying to have two versions of
|
||||
the same package installed in the same generation of a profile will
|
||||
lead to an error in building the generation, due to file name
|
||||
clashes between the two versions. However, this is not the case for
|
||||
all packages.
|
||||
|
||||
- `--remove-all`; `-r`\
|
||||
Remove all previously installed packages first. This is equivalent
|
||||
to running `nix-env -e '.*'` first, except that everything happens
|
||||
in a single transaction.
|
||||
|
||||
## Examples
|
||||
|
||||
To install a package using a specific attribute path from the active Nix expression:
|
||||
|
||||
```console
|
||||
$ nix-env -iA gcc40mips
|
||||
installing `gcc-4.0.2'
|
||||
$ nix-env -iA xorg.xorgserver
|
||||
installing `xorg-server-1.2.0'
|
||||
```
|
||||
|
||||
To install a specific version of `gcc` using the derivation name:
|
||||
|
||||
```console
|
||||
$ nix-env --install gcc-3.3.2
|
||||
installing `gcc-3.3.2'
|
||||
uninstalling `gcc-3.1'
|
||||
```
|
||||
|
||||
Using attribute path for selecting a package is preferred,
|
||||
as it is much faster and there will not be multiple matches.
|
||||
|
||||
Note the previously installed version is removed, since
|
||||
`--preserve-installed` was not specified.
|
||||
|
||||
To install an arbitrary version:
|
||||
|
||||
```console
|
||||
$ nix-env --install gcc
|
||||
installing `gcc-3.3.2'
|
||||
```
|
||||
|
||||
To install all derivations in the Nix expression `foo.nix`:
|
||||
|
||||
```console
|
||||
$ nix-env -f ~/foo.nix -i '.*'
|
||||
```
|
||||
|
||||
To copy the store path with symbolic name `gcc` from another profile:
|
||||
|
||||
```console
|
||||
$ nix-env -i --from-profile /nix/var/nix/profiles/foo gcc
|
||||
```
|
||||
|
||||
To install a specific [store derivation] (typically created by
|
||||
`nix-instantiate`):
|
||||
|
||||
```console
|
||||
$ nix-env -i /nix/store/fibjb1bfbpm5mrsxc4mh2d8n37sxh91i-gcc-3.4.3.drv
|
||||
```
|
||||
|
||||
To install a specific output path:
|
||||
|
||||
```console
|
||||
$ nix-env -i /nix/store/y3cgx0xj1p4iv9x0pnnmdhr8iyg741vk-gcc-3.4.3
|
||||
```
|
||||
|
||||
To install from a Nix expression specified on the command-line:
|
||||
|
||||
```console
|
||||
$ nix-env -f ./foo.nix -i -E \
|
||||
'f: (f {system = "i686-linux";}).subversionWithJava'
|
||||
```
|
||||
|
||||
I.e., this evaluates to `(f: (f {system =
|
||||
"i686-linux";}).subversionWithJava) (import ./foo.nix)`, thus selecting
|
||||
the `subversionWithJava` attribute from the set returned by calling the
|
||||
function defined in `./foo.nix`.
|
||||
|
||||
A dry-run tells you which paths will be downloaded or built from source:
|
||||
|
||||
```console
|
||||
$ nix-env -f '<nixpkgs>' -iA hello --dry-run
|
||||
(dry run; not doing anything)
|
||||
installing ‘hello-2.10’
|
||||
this path will be fetched (0.04 MiB download, 0.19 MiB unpacked):
|
||||
/nix/store/wkhdf9jinag5750mqlax6z2zbwhqb76n-hello-2.10
|
||||
...
|
||||
```
|
||||
|
||||
To install Firefox from the latest revision in the Nixpkgs/NixOS 14.12
|
||||
channel:
|
||||
|
||||
```console
|
||||
$ nix-env -f https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz -iA firefox
|
||||
```

# Operation `--upgrade`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` {`--upgrade` | `-u`} *args*
|
||||
[`--lt` | `--leq` | `--eq` | `--always`]
|
||||
[{`--prebuilt-only` | `-b`}]
|
||||
[{`--attr` | `-A`}]
|
||||
[`--from-expression`] [`-E`]
|
||||
[`--from-profile` *path*]
|
||||
[`--preserve-installed` | `-P`]
|
||||
|
||||
## Description
|
||||
|
||||
The upgrade operation creates a new user environment, based on the
|
||||
current generation of the active profile, in which all store paths are
|
||||
replaced for which there are newer versions in the set of paths
|
||||
described by *args*. Paths for which there are no newer versions are
|
||||
left untouched; this is not an error. It is also not an error if an
|
||||
element of *args* matches no installed derivations.
|
||||
|
||||
For a description of how *args* is mapped to a set of store paths, see
|
||||
[`--install`](#operation---install). If *args* describes multiple
|
||||
store paths with the same symbolic name, only the one with the highest
|
||||
version is installed.
|
||||
|
||||
## Flags
|
||||
|
||||
- `--lt`\
|
||||
Only upgrade a derivation to newer versions. This is the default.
|
||||
|
||||
- `--leq`\
|
||||
In addition to upgrading to newer versions, also “upgrade” to
|
||||
derivations that have the same version. Version are not a unique
|
||||
identification of a derivation, so there may be many derivations
|
||||
that have the same version. This flag may be useful to force
|
||||
“synchronisation” between the installed and available derivations.
|
||||
|
||||
- `--eq`\
|
||||
*Only* “upgrade” to derivations that have the same version. This may
|
||||
not seem very useful, but it actually is, e.g., when there is a new
|
||||
release of Nixpkgs and you want to replace installed applications
|
||||
with the same versions built against newer dependencies (to reduce
|
||||
the number of dependencies floating around on your system).
|
||||
|
||||
- `--always`\
|
||||
In addition to upgrading to newer versions, also “upgrade” to
|
||||
derivations that have the same or a lower version. I.e., derivations
|
||||
may actually be downgraded depending on what is available in the
|
||||
active Nix expression.
|
||||
|
||||
For the other flags, see `--install`.
|
||||
|
||||
## Examples
|
||||
|
||||
```console
|
||||
$ nix-env --upgrade -A nixpkgs.gcc
|
||||
upgrading `gcc-3.3.1' to `gcc-3.4'
|
||||
```
|
||||
|
||||
When there are no updates available, nothing will happen:
|
||||
|
||||
```console
|
||||
$ nix-env --upgrade -A nixpkgs.pan
|
||||
```
|
||||
|
||||
Using `-A` is preferred when possible, as it is faster and unambiguous but
|
||||
it is also possible to upgrade to a specific version by matching the derivation name:
|
||||
|
||||
```console
|
||||
$ nix-env -u gcc-3.3.2 --always
|
||||
upgrading `gcc-3.4' to `gcc-3.3.2'
|
||||
```
|
||||
|
||||
To try to upgrade everything
|
||||
(matching packages based on the part of the derivation name without version):
|
||||
|
||||
```console
|
||||
$ nix-env -u
|
||||
upgrading `hello-2.1.2' to `hello-2.1.3'
|
||||
upgrading `mozilla-1.2' to `mozilla-1.4'
|
||||
```
|
||||
|
||||
## Versions
|
||||
|
||||
The upgrade operation determines whether a derivation `y` is an upgrade
|
||||
of a derivation `x` by looking at their respective `name` attributes.
|
||||
The names (e.g., `gcc-3.3.1` are split into two parts: the package name
|
||||
(`gcc`), and the version (`3.3.1`). The version part starts after the
|
||||
first dash not followed by a letter. `y` is considered an upgrade of `x`
|
||||
if their package names match, and the version of `y` is higher than that
|
||||
of `x`.
|
||||
|
||||
The versions are compared by splitting them into contiguous components
|
||||
of numbers and letters. E.g., `3.3.1pre5` is split into `[3, 3, 1,
|
||||
"pre", 5]`. These lists are then compared lexicographically (from left
|
||||
to right). Corresponding components `a` and `b` are compared as follows.
|
||||
If they are both numbers, integer comparison is used. If `a` is an empty
|
||||
string and `b` is a number, `a` is considered less than `b`. The special
|
||||
string component `pre` (for *pre-release*) is considered to be less than
|
||||
other components. String components are considered less than number
|
||||
components. Otherwise, they are compared lexicographically (i.e., using
|
||||
case-sensitive string comparison).
|
||||
|
||||
This is illustrated by the following examples:
|
||||
|
||||
1.0 < 2.3
|
||||
2.1 < 2.3
|
||||
2.3 = 2.3
|
||||
2.5 > 2.3
|
||||
3.1 > 2.3
|
||||
2.3.1 > 2.3
|
||||
2.3.1 > 2.3a
|
||||
2.3pre1 < 2.3
|
||||
2.3pre3 < 2.3pre12
|
||||
2.3a < 2.3c
|
||||
2.3pre1 < 2.3c
|
||||
2.3pre1 < 2.3q

# Operation `--uninstall`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` {`--uninstall` | `-e`} *drvnames…*
|
||||
|
||||
## Description
|
||||
|
||||
The uninstall operation creates a new user environment, based on the
|
||||
current generation of the active profile, from which the store paths
|
||||
designated by the symbolic names *drvnames* are removed.
|
||||
|
||||
## Examples
|
||||
|
||||
```console
|
||||
$ nix-env --uninstall gcc
|
||||
$ nix-env -e '.*' (remove everything)
|
||||
```
|
||||
|
||||
# Operation `--set`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` `--set` *drvname*
|
||||
|
||||
## Description
|
||||
|
||||
The `--set` operation modifies the current generation of a profile so
|
||||
that it contains exactly the specified derivation, and nothing else.
|
||||
|
||||
## Examples
|
||||
|
||||
The following updates a profile such that its current generation will
|
||||
contain just Firefox:
|
||||
|
||||
```console
|
||||
$ nix-env -p /nix/var/nix/profiles/browser --set firefox
|
||||
```
|
||||
|
||||
# Operation `--set-flag`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` `--set-flag` *name* *value* *drvnames*
|
||||
|
||||
## Description
|
||||
|
||||
The `--set-flag` operation allows meta attributes of installed packages
|
||||
to be modified. There are several attributes that can be usefully
|
||||
modified, because they affect the behaviour of `nix-env` or the user
|
||||
environment build script:
|
||||
|
||||
- `priority` can be changed to resolve filename clashes. The user
|
||||
environment build script uses the `meta.priority` attribute of
|
||||
derivations to resolve filename collisions between packages. Lower
|
||||
priority values denote a higher priority. For instance, the GCC
|
||||
wrapper package and the Binutils package in Nixpkgs both have a file
|
||||
`bin/ld`, so previously if you tried to install both you would get a
|
||||
collision. Now, on the other hand, the GCC wrapper declares a higher
|
||||
priority than Binutils, so the former’s `bin/ld` is symlinked in the
|
||||
user environment.
|
||||
|
||||
- `keep` can be set to `true` to prevent the package from being
|
||||
upgraded or replaced. This is useful if you want to hang on to an
|
||||
older version of a package.
|
||||
|
||||
- `active` can be set to `false` to “disable” the package. That is, no
|
||||
symlinks will be generated to the files of the package, but it
|
||||
remains part of the profile (so it won’t be garbage-collected). It
|
||||
can be set back to `true` to re-enable the package.
|
||||
|
||||
## Examples
|
||||
|
||||
To prevent the currently installed Firefox from being upgraded:
|
||||
|
||||
```console
|
||||
$ nix-env --set-flag keep true firefox
|
||||
```
|
||||
|
||||
After this, `nix-env -u` will ignore Firefox.
|
||||
|
||||
To disable the currently installed Firefox, then install a new Firefox
|
||||
while the old remains part of the profile:
|
||||
|
||||
```console
|
||||
$ nix-env -q
|
||||
firefox-2.0.0.9 (the current one)
|
||||
|
||||
$ nix-env --preserve-installed -i firefox-2.0.0.11
|
||||
installing `firefox-2.0.0.11'
|
||||
building path(s) `/nix/store/myy0y59q3ig70dgq37jqwg1j0rsapzsl-user-environment'
|
||||
collision between `/nix/store/...-firefox-2.0.0.11/bin/firefox'
|
||||
and `/nix/store/...-firefox-2.0.0.9/bin/firefox'.
|
||||
(i.e., can’t have two active at the same time)
|
||||
|
||||
$ nix-env --set-flag active false firefox
|
||||
setting flag on `firefox-2.0.0.9'
|
||||
|
||||
$ nix-env --preserve-installed -i firefox-2.0.0.11
|
||||
installing `firefox-2.0.0.11'
|
||||
|
||||
$ nix-env -q
|
||||
firefox-2.0.0.11 (the enabled one)
|
||||
firefox-2.0.0.9 (the disabled one)
|
||||
```
|
||||
|
||||
To make files from `binutils` take precedence over files from `gcc`:
|
||||
|
||||
```console
|
||||
$ nix-env --set-flag priority 5 binutils
|
||||
$ nix-env --set-flag priority 10 gcc
|
||||
```
|
||||
|
||||
# Operation `--query`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` {`--query` | `-q`} *names…*
|
||||
[`--installed` | `--available` | `-a`]
|
||||
[{`--status` | `-s`}]
|
||||
[{`--attr-path` | `-P`}]
|
||||
[`--no-name`]
|
||||
[{`--compare-versions` | `-c`}]

|
||||
[`--json`]
|
||||
[{`--prebuilt-only` | `-b`}]
|
||||
[{`--attr` | `-A`} *attribute-path*]
|
||||
|
||||
## Description
|
||||
|
||||
The query operation displays information about either the store paths
|
||||
that are installed in the current generation of the active profile
|
||||
(`--installed`), or the derivations that are available for installation
|
||||
in the active Nix expression (`--available`). It only prints information
|
||||
about derivations whose symbolic name matches one of *names*.
|
||||
|
||||
The derivations are sorted by their `name` attributes.
|
||||
|
||||
## Source selection
|
||||
|
||||
The following flags specify the set of things on which the query
|
||||
operates.
|
||||
|
||||
- `--installed`\
|
||||
The query operates on the store paths that are installed in the
|
||||
current generation of the active profile. This is the default.
|
||||
|
||||
- `--available`; `-a`\
|
||||
The query operates on the derivations that are available in the
|
||||
active Nix expression.
|
||||
|
||||
## Queries
|
||||
|
||||
The following flags specify what information to display about the
|
||||
selected derivations. Multiple flags may be specified, in which case the
|
||||
information is shown in the order given here. Note that the name of the
|
||||
derivation is shown unless `--no-name` is specified.
|
||||
|
||||
- `--xml`\
|
||||
Print the result in an XML representation suitable for automatic
|
||||
processing by other tools. The root element is called `items`, which
|
||||
contains a `item` element for each available or installed
|
||||
derivation. The fields discussed below are all stored in attributes
|
||||
of the `item` elements.
|
||||
|
||||
- `--json`\
|
||||
Print the result in a JSON representation suitable for automatic
|
||||
processing by other tools.
|
||||
|
||||
- `--prebuilt-only` / `-b`\
|
||||
Show only derivations for which a substitute is registered, i.e.,
|
||||
there is a pre-built binary available that can be downloaded in lieu
|
||||
of building the derivation. Thus, this shows all packages that
|
||||
probably can be installed quickly.
|
||||
|
||||
- `--status`; `-s`\
|
||||
Print the *status* of the derivation. The status consists of three
|
||||
characters. The first is `I` or `-`, indicating whether the
|
||||
derivation is currently installed in the current generation of the
|
||||
active profile. This is by definition the case for `--installed`,
|
||||
but not for `--available`. The second is `P` or `-`, indicating
|
||||
whether the derivation is present on the system. This indicates
|
||||
whether installation of an available derivation will require the
|
||||
derivation to be built. The third is `S` or `-`, indicating whether
|
||||
a substitute is available for the derivation.
|
||||
|
||||
- `--attr-path`; `-P`\
|
||||
Print the *attribute path* of the derivation, which can be used to
|
||||
unambiguously select it using the `--attr` option available in
|
||||
commands that install derivations like `nix-env --install`. This
|
||||
option only works together with `--available`
|
||||
|
||||
- `--no-name`\
|
||||
Suppress printing of the `name` attribute of each derivation.
|
||||
|
||||
- `--compare-versions` / `-c`\
|
||||
Compare installed versions to available versions, or vice versa (if
|
||||
`--available` is given). This is useful for quickly seeing whether
|
||||
upgrades for installed packages are available in a Nix expression. A
|
||||
column is added with the following meaning:
|
||||
|
||||
- `<` *version*\
|
||||
A newer version of the package is available or installed.
|
||||
|
||||
- `=` *version*\
|
||||
At most the same version of the package is available or
|
||||
installed.
|
||||
|
||||
- `>` *version*\
|
||||
Only older versions of the package are available or installed.
|
||||
|
||||
- `- ?`\
|
||||
No version of the package is available or installed.
|
||||
|
||||
- `--system`\
|
||||
Print the `system` attribute of the derivation.
|
||||
|
||||
- `--drv-path`\
|
||||
Print the path of the [store derivation].
|
||||
|
||||
- `--out-path`\
|
||||
Print the output path of the derivation.
|
||||
|
||||
- `--description`\
|
||||
Print a short (one-line) description of the derivation, if
|
||||
available. The description is taken from the `meta.description`
|
||||
attribute of the derivation.
|
||||
|
||||
- `--meta`\
|
||||
Print all of the meta-attributes of the derivation. This option is
|
||||
only available with `--xml` or `--json`.
|
||||
|
||||

# Operation `--delete-generations`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` `--delete-generations` *generations*
|
||||
|
||||
## Description
|
||||
|
||||
This operation deletes the specified generations of the current profile.
|
||||
The generations can be a list of generation numbers, the special value
|
||||
`old` to delete all non-current generations, a value such as `30d` to
|
||||
delete all generations older than the specified number of days (except
|
||||
for the generation that was active at that point in time), or a value
|
||||
such as `+5` to keep the last `5` generations ignoring any newer than
|
||||
current, e.g., if `30` is the current generation `+5` will delete
|
||||
generation `25` and all older generations. Periodically deleting old
|
||||
generations is important to make garbage collection effective.
|
||||
|
||||
## Examples
|
||||
|
||||
```console
|
||||
$ nix-env --delete-generations 3 4 8
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-env --delete-generations +5
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-env --delete-generations 30d
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-env -p other_profile --delete-generations old
|
||||
```
|
||||
|
||||
# Operation `--switch-generation`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` {`--switch-generation` | `-G`} *generation*
|
||||
|
||||
## Description
|
||||
|
||||
This operation makes generation number *generation* the current
|
||||
generation of the active profile. That is, if the `profile` is the path
|
||||
to the active profile, then the symlink `profile` is made to point to
|
||||
`profile-generation-link`, which is in turn a symlink to the actual user
|
||||
environment in the Nix store.
|
||||
|
||||
Switching will fail if the specified generation does not exist.
|
||||
|
||||
## Examples
|
||||
|
||||
```console
|
||||
$ nix-env -G 42
|
||||
switching from generation 50 to 42
|
||||
```
|
||||
|
||||
# Operation `--rollback`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-env` `--rollback`
|
||||
|
||||
## Description
|
||||
|
||||
This operation switches to the “previous” generation of the active
|
||||
profile, that is, the highest numbered generation lower than the current
|
||||
generation, if it exists. It is just a convenience wrapper around
|
||||
`--list-generations` and `--switch-generation`.
|
||||
|
||||
## Examples
|
||||
|
||||
```console
|
||||
$ nix-env --rollback
|
||||
switching from generation 92 to 91
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-env --rollback
|
||||
error: no generation older than the current (91) exists
|
||||
```
|
||||
|
||||
# Environment variables
|
||||
|
||||
- `NIX_PROFILE`\
|
||||
Location of the Nix profile. Defaults to the target of the symlink
|
||||
`~/.nix-profile`, if it exists, or `/nix/var/nix/profiles/default`
|
||||
otherwise.

# Name

`nix-env --install` - add packages to user environment
|
||||
|
||||
# Synopsis
|
||||
|
||||
`nix-env` {`--install` | `-i`} *args…*
|
||||
[{`--prebuilt-only` | `-b`}]
|
||||
[{`--attr` | `-A`}]
|
||||
[`--from-expression`] [`-E`]
|
||||
[`--from-profile` *path*]
|
||||
[`--preserve-installed` | `-P`]
|
||||
[`--remove-all` | `-r`]
|
||||
|
||||
# Description
|
||||
|
||||
The install operation creates a new user environment, based on the
|
||||
current generation of the active profile, to which a set of store paths
|
||||
described by *args* is added. The arguments *args* map to store paths in
|
||||
a number of possible ways:
|
||||
|
||||
- By default, *args* is a set of derivation names denoting derivations
|
||||
in the active Nix expression. These are realised, and the resulting
|
||||
output paths are installed. Currently installed derivations with a
|
||||
name equal to the name of a derivation being added are removed
|
||||
unless the option `--preserve-installed` is specified.
|
||||
|
||||
If there are multiple derivations matching a name in *args* that
|
||||
have the same name (e.g., `gcc-3.3.6` and `gcc-4.1.1`), then the
|
||||
derivation with the highest *priority* is used. A derivation can
|
||||
define a priority by declaring the `meta.priority` attribute. This
|
||||
attribute should be a number, with a higher value denoting a lower
|
||||
priority. The default priority is `0`.
|
||||
|
||||
If there are multiple matching derivations with the same priority,
|
||||
then the derivation with the highest version will be installed.
|
||||
|
||||
You can force the installation of multiple derivations with the same
|
||||
name by being specific about the versions. For instance, `nix-env -i
|
||||
gcc-3.3.6 gcc-4.1.1` will install both version of GCC (and will
|
||||
probably cause a user environment conflict\!).
|
||||
|
||||
- If `--attr` (`-A`) is specified, the arguments are *attribute
|
||||
paths* that select attributes from the top-level Nix
|
||||
expression. This is faster than using derivation names and
|
||||
unambiguous. To find out the attribute paths of available
|
||||
packages, use `nix-env -qaP`.
|
||||
|
||||
- If `--from-profile` *path* is given, *args* is a set of names
|
||||
denoting installed store paths in the profile *path*. This is an
|
||||
easy way to copy user environment elements from one profile to
|
||||
another.
|
||||
|
||||
- If `--from-expression` is given, *args* are Nix
|
||||
[functions](@docroot@/language/constructs.md#functions)
|
||||
that are called with the active Nix expression as their single
|
||||
argument. The derivations returned by those function calls are
|
||||
installed. This allows derivations to be specified in an
|
||||
unambiguous way, which is necessary if there are multiple
|
||||
derivations with the same name.
|
||||
|
||||
- If *args* are [store derivations](@docroot@/glossary.md#gloss-store-derivation), then these are
|
||||
[realised](@docroot@/command-ref/nix-store/realise.md), and the resulting output paths
|
||||
are installed.
|
||||
|
||||
- If *args* are store paths that are not store derivations, then these
|
||||
are [realised](@docroot@/command-ref/nix-store/realise.md) and installed.
|
||||
|
||||
- By default all outputs are installed for each derivation. That can
|
||||
be reduced by setting `meta.outputsToInstall`.
|
||||
|
||||
# Flags
|
||||
|
||||
- `--prebuilt-only` / `-b`\
|
||||
Use only derivations for which a substitute is registered, i.e.,
|
||||
there is a pre-built binary available that can be downloaded in lieu
|
||||
of building the derivation. Thus, no packages will be built from
|
||||
source.
|
||||
|
||||
- `--preserve-installed` / `-P`\
|
||||
Do not remove derivations with a name matching one of the
|
||||
derivations being installed. Usually, trying to have two versions of
|
||||
the same package installed in the same generation of a profile will
|
||||
lead to an error in building the generation, due to file name
|
||||
clashes between the two versions. However, this is not the case for
|
||||
all packages.
|
||||
|
||||
- `--remove-all` / `-r`\
|
||||
Remove all previously installed packages first. This is equivalent
|
||||
to running `nix-env -e '.*'` first, except that everything happens
|
||||
in a single transaction.

|
||||
|
||||
# Examples
|
||||
|
||||
To install a package using a specific attribute path from the active Nix expression:
|
||||
|
||||
```console
|
||||
$ nix-env -iA gcc40mips
|
||||
installing `gcc-4.0.2'
|
||||
$ nix-env -iA xorg.xorgserver
|
||||
installing `xorg-server-1.2.0'
|
||||
```
|
||||
|
||||
To install a specific version of `gcc` using the derivation name:
|
||||
|
||||
```console
|
||||
$ nix-env --install gcc-3.3.2
|
||||
installing `gcc-3.3.2'
|
||||
uninstalling `gcc-3.1'
|
||||
```
|
||||
|
||||
Using attribute path for selecting a package is preferred,
|
||||
as it is much faster and there will not be multiple matches.
|
||||
|
||||
Note the previously installed version is removed, since
|
||||
`--preserve-installed` was not specified.
|
||||
|
||||
To install an arbitrary version:
|
||||
|
||||
```console
|
||||
$ nix-env --install gcc
|
||||
installing `gcc-3.3.2'
|
||||
```
|
||||
|
||||
To install all derivations in the Nix expression `foo.nix`:
|
||||
|
||||
```console
|
||||
$ nix-env -f ~/foo.nix -i '.*'
|
||||
```
|
||||
|
||||
To copy the store path with symbolic name `gcc` from another profile:
|
||||
|
||||
```console
|
||||
$ nix-env -i --from-profile /nix/var/nix/profiles/foo gcc
|
||||
```
|
||||
|
||||
To install a specific [store derivation] (typically created by
|
||||
`nix-instantiate`):
|
||||
|
||||
```console
|
||||
$ nix-env -i /nix/store/fibjb1bfbpm5mrsxc4mh2d8n37sxh91i-gcc-3.4.3.drv
|
||||
```
|
||||
|
||||
To install a specific output path:
|
||||
|
||||
```console
|
||||
$ nix-env -i /nix/store/y3cgx0xj1p4iv9x0pnnmdhr8iyg741vk-gcc-3.4.3
|
||||
```
|
||||
|
||||
To install from a Nix expression specified on the command-line:
|
||||
|
||||
```console
|
||||
$ nix-env -f ./foo.nix -i -E \
|
||||
'f: (f {system = "i686-linux";}).subversionWithJava'
|
||||
```
|
||||
|
||||
I.e., this evaluates to `(f: (f {system =
|
||||
"i686-linux";}).subversionWithJava) (import ./foo.nix)`, thus selecting
|
||||
the `subversionWithJava` attribute from the set returned by calling the
|
||||
function defined in `./foo.nix`.
|
||||
|
||||
A dry-run tells you which paths will be downloaded or built from source:
|
||||
|
||||
```console
|
||||
$ nix-env -f '<nixpkgs>' -iA hello --dry-run
|
||||
(dry run; not doing anything)
|
||||
installing ‘hello-2.10’
|
||||
this path will be fetched (0.04 MiB download, 0.19 MiB unpacked):
|
||||
/nix/store/wkhdf9jinag5750mqlax6z2zbwhqb76n-hello-2.10
|
||||
...
|
||||
```
|
||||
|
||||
To install Firefox from the latest revision in the Nixpkgs/NixOS 14.12
|
||||
channel:
|
||||
|
||||
```console
|
||||
$ nix-env -f https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz -iA firefox
|
||||

# Options
|
||||
|
||||
The following options are allowed for all `nix-env` operations, but may not always have an effect.
|
||||
|
||||
- `--file` / `-f` *path*\
|
||||
Specifies the Nix expression (designated below as the *active Nix
|
||||
expression*) used by the `--install`, `--upgrade`, and `--query
|
||||
--available` operations to obtain derivations. The default is
|
||||
`~/.nix-defexpr`.
|
||||
|
||||
If the argument starts with `http://` or `https://`, it is
|
||||
interpreted as the URL of a tarball that will be downloaded and
|
||||
unpacked to a temporary location. The tarball must include a single
|
||||
top-level directory containing at least a file named `default.nix`.
|
||||
|
||||
- `--profile` / `-p` *path*\
|
||||
Specifies the profile to be used by those operations that operate on
|
||||
a profile (designated below as the *active profile*). A profile is a
|
||||
sequence of user environments called *generations*, one of which is
|
||||
the *current generation*.
|
||||
|
||||
- `--dry-run`\
|
||||
For the `--install`, `--upgrade`, `--uninstall`,
|
||||
`--switch-generation`, `--delete-generations` and `--rollback`
|
||||
operations, this flag will cause `nix-env` to print what *would* be
|
||||
done if this flag had not been specified, without actually doing it.
|
||||
|
||||
`--dry-run` also prints out which paths will be
|
||||
[substituted](@docroot@/glossary.md) (i.e., downloaded) and which paths
|
||||
will be built from source (because no substitute is available).
|
||||
|
||||
- `--system-filter` *system*\
|
||||
By default, operations such as `--query
|
||||
--available` show derivations matching any platform. This option
|
||||
allows you to use derivations for the specified platform *system*.

# Description
|
||||
|
||||
The query operation displays information about either the store paths
|
||||
that are installed in the current generation of the active profile
|
||||
(`--installed`), or the derivations that are available for installation
|
||||
in the active Nix expression (`--available`). It only prints information
|
||||
about derivations whose symbolic name matches one of *names*.
|
||||
|
||||
The derivations are sorted by their `name` attributes.
|
||||
|
||||
# Source selection
|
||||
|
||||
The following flags specify the set of things on which the query
|
||||
operates.
|
||||
|
||||
- `--installed`\
|
||||
The query operates on the store paths that are installed in the
|
||||
current generation of the active profile. This is the default.
|
||||
|
||||
- `--available`; `-a`\
|
||||
The query operates on the derivations that are available in the
|
||||
active Nix expression.
|
||||
|
||||
# Queries
|
||||
|
||||
The following flags specify what information to display about the
|
||||
selected derivations. Multiple flags may be specified, in which case the
|
||||
information is shown in the order given here. Note that the name of the
|
||||
derivation is shown unless `--no-name` is specified.
|
||||
|
||||
- `--xml`\
|
||||
Print the result in an XML representation suitable for automatic
|
||||
processing by other tools. The root element is called `items`, which
|
||||
contains a `item` element for each available or installed
|
||||
derivation. The fields discussed below are all stored in attributes
|
||||
of the `item` elements.
|
||||
|
||||
- `--json`\
|
||||
Print the result in a JSON representation suitable for automatic
|
||||
processing by other tools.
|
||||
|
||||
- `--prebuilt-only` / `-b`\
|
||||
Show only derivations for which a substitute is registered, i.e.,
|
||||
there is a pre-built binary available that can be downloaded in lieu
|
||||
of building the derivation. Thus, this shows all packages that
|
||||
probably can be installed quickly.
|
||||
|
||||
- `--status`; `-s`\
|
||||
Print the *status* of the derivation. The status consists of three
|
||||
characters. The first is `I` or `-`, indicating whether the
|
||||
derivation is currently installed in the current generation of the
|
||||
active profile. This is by definition the case for `--installed`,
|
||||
but not for `--available`. The second is `P` or `-`, indicating
|
||||
whether the derivation is present on the system. This indicates
|
||||
whether installation of an available derivation will require the
|
||||
derivation to be built. The third is `S` or `-`, indicating whether
|
||||
a substitute is available for the derivation.
|
||||
|
||||
- `--attr-path`; `-P`\
|
||||
Print the *attribute path* of the derivation, which can be used to
|
||||
unambiguously select it using the `--attr` option available in
|
||||
commands that install derivations like `nix-env --install`. This
|
||||
option only works together with `--available`
|
||||
|
||||
- `--no-name`\
|
||||
Suppress printing of the `name` attribute of each derivation.
|
||||
|
||||
- `--compare-versions` / `-c`\
|
||||
Compare installed versions to available versions, or vice versa (if
|
||||
`--available` is given). This is useful for quickly seeing whether
|
||||
upgrades for installed packages are available in a Nix expression. A
|
||||
column is added with the following meaning:
|
||||
|
||||
- `<` *version*\
|
||||
A newer version of the package is available or installed.
|
||||
|
||||
- `=` *version*\
|
||||
At most the same version of the package is available or
|
||||
installed.
|
||||
|
||||
- `>` *version*\
|
||||
Only older versions of the package are available or installed.
|
||||
|
||||
- `- ?`\
|
||||
No version of the package is available or installed.
|
||||
|
||||
- `--system`\
|
||||
Print the `system` attribute of the derivation.
|
||||
|
||||
- `--drv-path`\
|
||||
Print the path of the [store derivation](@docroot@/glossary.md#gloss-store-derivation).
|
||||
|
||||
- `--out-path`\
|
||||
Print the output path of the derivation.
|
||||
|
||||
- `--description`\
|
||||
Print a short (one-line) description of the derivation, if
|
||||
available. The description is taken from the `meta.description`
|
||||
attribute of the derivation.
|
||||
|
||||
- `--meta`\
|
||||
Print all of the meta-attributes of the derivation. This option is
|
||||
only available with `--xml` or `--json`.

`nix-env` `--rollback`
|

|

# Description
|

|

This operation switches to the “previous” generation of the active
|

profile, that is, the highest numbered generation lower than the current
|
||||
generation, if it exists. It is just a convenience wrapper around

# Name
|
||||
|
||||
`nix-env --set-flag` - modify meta attributes of installed packages
|
||||
|
||||
# Synopsis
|
||||
|
||||
`nix-env` `--set-flag` *name* *value* *drvnames*
|
||||
|
||||
# Description
|
||||
|
||||
The `--set-flag` operation allows meta attributes of installed packages
|
||||
to be modified. There are several attributes that can be usefully
|
||||
modified, because they affect the behaviour of `nix-env` or the user
|
||||
environment build script:
|
||||
|
||||
- `priority` can be changed to resolve filename clashes. The user
|
||||
environment build script uses the `meta.priority` attribute of
|
||||
derivations to resolve filename collisions between packages. Lower
|
||||
priority values denote a higher priority. For instance, the GCC
|
||||
wrapper package and the Binutils package in Nixpkgs both have a file
|
||||
`bin/ld`, so previously if you tried to install both you would get a
|
||||
collision. Now, on the other hand, the GCC wrapper declares a higher
|
||||
priority than Binutils, so the former’s `bin/ld` is symlinked in the
|
||||
user environment.
|
||||
|
||||
- `keep` can be set to `true` to prevent the package from being
|
||||
upgraded or replaced. This is useful if you want to hang on to an
|
||||
older version of a package.
|
||||
|
||||
- `active` can be set to `false` to “disable” the package. That is, no
|
||||
symlinks will be generated to the files of the package, but it
|
||||
remains part of the profile (so it won’t be garbage-collected). It
|
||||
can be set back to `true` to re-enable the package.

||||
{{#include ./opt-common.md}}

|
||||
{{#include ../opt-common.md}}
|
||||
|
||||
{{#include ../env-common.md}}
|
||||
|
||||
# Examples
|
||||
|
||||
To prevent the currently installed Firefox from being upgraded:
|
||||
|
||||
```console
|
||||
$ nix-env --set-flag keep true firefox
|
||||
```
|
||||
|
||||
After this, `nix-env -u` will ignore Firefox.
|
||||
|
||||
To disable the currently installed Firefox, then install a new Firefox
|
||||
while the old remains part of the profile:
|
||||
|
||||
```console
|
||||
$ nix-env -q
|
||||
firefox-2.0.0.9 (the current one)
|
||||
|
||||
$ nix-env --preserve-installed -i firefox-2.0.0.11
|
||||
installing `firefox-2.0.0.11'
|
||||
building path(s) `/nix/store/myy0y59q3ig70dgq37jqwg1j0rsapzsl-user-environment'
|
||||
collision between `/nix/store/...-firefox-2.0.0.11/bin/firefox'
|
||||
and `/nix/store/...-firefox-2.0.0.9/bin/firefox'.
|
||||
(i.e., can’t have two active at the same time)
|
||||
|
||||
$ nix-env --set-flag active false firefox
|
||||
setting flag on `firefox-2.0.0.9'
|
||||
|
||||
$ nix-env --preserve-installed -i firefox-2.0.0.11
|
||||
installing `firefox-2.0.0.11'
|
||||
|
||||
$ nix-env -q
|
||||
firefox-2.0.0.11 (the enabled one)
|
||||
firefox-2.0.0.9 (the disabled one)
|
||||
```
|
||||
|
||||
To make files from `binutils` take precedence over files from `gcc`:
|
||||
|
||||
```console
|
||||
$ nix-env --set-flag priority 5 binutils
|
||||
$ nix-env --set-flag priority 10 gcc
|

`nix-env` `--set` *drvname*
|
||||
|

## Description
|
||||
|

The `--set` operation modifies the current generation of a profile so
|
||||
that it contains exactly the specified derivation, and nothing else.

This operation makes generation number *generation* the current

to the active profile, then the symlink `profile` is made to point to
|
||||
`profile-generation-link`, which is in turn a symlink to the actual user
|
||||
environment in the Nix store.
|
||||
|
||||
Switching will fail if the specified generation does not exist.

|

[`--preserve-installed` | `-P`]
|
||||
|
||||
# Description
|
||||
|
||||
The upgrade operation creates a new user environment, based on the
|
||||
current generation of the active profile, in which all store paths are
|
||||
replaced for which there are newer versions in the set of paths
|
||||
described by *args*. Paths for which there are no newer versions are
|
||||
left untouched; this is not an error. It is also not an error if an
|
||||
element of *args* matches no installed derivations.
|
||||
|
||||
For a description of how *args* is mapped to a set of store paths, see
|
||||
[`--install`](#operation---install). If *args* describes multiple
|
||||
store paths with the same symbolic name, only the one with the highest
|
||||
version is installed.
|
||||
|
||||
# Flags
|
||||
|
||||
- `--lt`\
|
||||
Only upgrade a derivation to newer versions. This is the default.
|
||||
|
||||
- `--leq`\
|
||||
In addition to upgrading to newer versions, also “upgrade” to
|
||||
derivations that have the same version. Version are not a unique
|
||||
identification of a derivation, so there may be many derivations
|
||||
that have the same version. This flag may be useful to force
|
||||
“synchronisation” between the installed and available derivations.
|
||||
|
||||
- `--eq`\
|
||||
*Only* “upgrade” to derivations that have the same version. This may
|
||||
not seem very useful, but it actually is, e.g., when there is a new
|
||||
release of Nixpkgs and you want to replace installed applications
|
||||
with the same versions built against newer dependencies (to reduce
|
||||
the number of dependencies floating around on your system).
|
||||
|
||||
- `--always`\
|
||||
In addition to upgrading to newer versions, also “upgrade” to
|
||||
derivations that have the same or a lower version. I.e., derivations
|
||||
may actually be downgraded depending on what is available in the
|
||||
active Nix expression.
|
||||
|
||||
- `--prebuilt-only` / `-b`\
|
||||
Use only derivations for which a substitute is registered, i.e.,
|
||||
there is a pre-built binary available that can be downloaded in lieu
|
||||
of building the derivation. Thus, no packages will be built from
|
||||
source.
|
||||
|
||||
- `--preserve-installed` / `-P`\
|
||||
Do not remove derivations with a name matching one of the
|
||||
derivations being installed. Usually, trying to have two versions of
|
||||
the same package installed in the same generation of a profile will
|
||||
lead to an error in building the generation, due to file name
|
||||
clashes between the two versions. However, this is not the case for
|
||||
all packages.

# Examples
|
||||
|
||||
```console
|
||||
$ nix-env --upgrade -A nixpkgs.gcc
|
||||
upgrading `gcc-3.3.1' to `gcc-3.4'
|
||||
```
|
||||
|
||||
When there are no updates available, nothing will happen:
|
||||
|
||||
```console
|
||||
$ nix-env --upgrade -A nixpkgs.pan
|
||||
```
|
||||
|
||||
Using `-A` is preferred when possible, as it is faster and unambiguous but
|
||||
it is also possible to upgrade to a specific version by matching the derivation name:
|
||||
|
||||
```console
|
||||
$ nix-env -u gcc-3.3.2 --always
|
||||
upgrading `gcc-3.4' to `gcc-3.3.2'
|
||||
```
|
||||
|
||||
To try to upgrade everything
|
||||
(matching packages based on the part of the derivation name without version):
|
||||
|
||||
```console
|
||||
$ nix-env -u
|
||||
upgrading `hello-2.1.2' to `hello-2.1.3'
|
||||
upgrading `mozilla-1.2' to `mozilla-1.4'
|
||||
```
|
||||
|
||||
# Versions
|
||||
|
||||
The upgrade operation determines whether a derivation `y` is an upgrade
|
||||
of a derivation `x` by looking at their respective `name` attributes.
|
||||
The names (e.g., `gcc-3.3.1` are split into two parts: the package name
|
||||
(`gcc`), and the version (`3.3.1`). The version part starts after the
|
||||
first dash not followed by a letter. `y` is considered an upgrade of `x`
|
||||
if their package names match, and the version of `y` is higher than that
|
||||
of `x`.
|
||||
|
||||
The versions are compared by splitting them into contiguous components
|
||||
of numbers and letters. E.g., `3.3.1pre5` is split into `[3, 3, 1,
|
||||
"pre", 5]`. These lists are then compared lexicographically (from left
|
||||
to right). Corresponding components `a` and `b` are compared as follows.
|
||||
If they are both numbers, integer comparison is used. If `a` is an empty
|
||||
string and `b` is a number, `a` is considered less than `b`. The special
|
||||
string component `pre` (for *pre-release*) is considered to be less than
|
||||
other components. String components are considered less than number
|
||||
components. Otherwise, they are compared lexicographically (i.e., using
|
||||
case-sensitive string comparison).
|
||||
|
||||
This is illustrated by the following examples:
|
||||
|
||||
1.0 < 2.3
|
||||
2.1 < 2.3
|
||||
2.3 = 2.3
|
||||
2.5 > 2.3
|
||||
3.1 > 2.3
|
||||
2.3.1 > 2.3
|
||||
2.3.1 > 2.3a
|
||||
2.3pre1 < 2.3
|
||||
2.3pre3 < 2.3pre12
|
||||
2.3a < 2.3c
|
||||
2.3pre1 < 2.3c
|
||||
2.3pre1 < 2.3q

The command `nix-store` performs primitive operations on the Nix store.

You generally do not need to run this command manually.

`nix-store` takes exactly one *operation* flag which indicates the

|

|

# Common options

|

|

Causes the result of a realisation (`--realise` and
|
||||
`--force-realise`) to be registered as a root of the garbage
|
||||
collector. *path* will be created as a symlink to the resulting
|
||||
store path. In addition, a uniquely named symlink to *path* will
|
||||
be created in `/nix/var/nix/gcroots/auto/`. For instance,
|
||||
|
||||
```console
|
||||
$ nix-store --add-root /home/eelco/bla/result -r ...

|
||||
$ ls -l /nix/var/nix/gcroots/auto

|
||||
```
|
||||
|
||||
Thus, when `/home/eelco/bla/result` is removed, the GC root in the
|
||||
`auto` directory becomes a dangling symlink and will be ignored by
|
||||
the collector.

> location.
|
||||
|
||||
If there are multiple results, then multiple symlinks will be
|
||||
created by sequentially numbering symlinks beyond the first one
|
||||
(e.g., `foo`, `foo-2`, `foo-3`, and so on).

# Operation `--realise`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` {`--realise` | `-r`} *paths…* [`--dry-run`]
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--realise` essentially “builds” the specified store
|
||||
paths. Realisation is a somewhat overloaded term:
|
||||
|
||||
- If the store path is a *derivation*, realisation ensures that the
|
||||
output paths of the derivation are [valid] (i.e.,
|
||||
the output path and its closure exist in the file system). This
|
||||
can be done in several ways. First, it is possible that the
|
||||
outputs are already valid, in which case we are done
|
||||
immediately. Otherwise, there may be [substitutes]
|
||||
that produce the outputs (e.g., by downloading them). Finally, the
|
||||
outputs can be produced by running the build task described
|
||||
by the derivation.
|
||||
|
||||
- If the store path is not a derivation, realisation ensures that the
|
||||
specified path is valid (i.e., it and its closure exist in the file
|
||||
system). If the path is already valid, we are done immediately.
|
||||
Otherwise, the path and any missing paths in its closure may be
|
||||
produced through substitutes. If there are no (successful)
|
||||
substitutes, realisation fails.
|
||||
|
||||
[valid]: ../glossary.md#gloss-validity
|
||||
[substitutes]: ../glossary.md#gloss-substitute
|
||||
|
||||
The output path of each derivation is printed on standard output. (For
|
||||
non-derivations argument, the argument itself is printed.)
|
||||
|
||||
The following flags are available:
|
||||
|
||||
- `--dry-run`\
|
||||
Print on standard error a description of what packages would be
|
||||
built or downloaded, without actually performing the operation.
|
||||
|
||||
- `--ignore-unknown`\
|
||||
If a non-derivation path does not have a substitute, then silently
|
||||
ignore it.
|
||||
|
||||
- `--check`\
|
||||
This option allows you to check whether a derivation is
|
||||
deterministic. It rebuilds the specified derivation and checks
|
||||
whether the result is bitwise-identical with the existing outputs,
|
||||
printing an error if that’s not the case. The outputs of the
|
||||
specified derivation must already exist. When used with `-K`, if an
|
||||
output path is not identical to the corresponding output from the
|
||||
previous build, the new output path is left in
|
||||
`/nix/store/name.check.`
|
||||
|
||||
Special exit codes:
|
||||
|
||||
- `100`\
|
||||
Generic build failure, the builder process returned with a non-zero
|
||||
exit code.
|
||||
|
||||
- `101`\
|
||||
Build timeout, the build was aborted because it did not complete
|
||||
within the specified `timeout`.
|
||||
|
||||
- `102`\
|
||||
Hash mismatch, the build output was rejected because it does not
|
||||
match the [`outputHash` attribute of the
|
||||
derivation](../language/advanced-attributes.md).
|
||||
|
||||
- `104`\
|
||||
Not deterministic, the build succeeded in check mode but the
|
||||
resulting output is not binary reproducible.
|
||||
|
||||
With the `--keep-going` flag it's possible for multiple failures to
|
||||
occur, in this case the 1xx status codes are or combined using binary
|
||||
or.

|

|
||||
## Examples
|
||||
|
||||
This operation is typically used to build [store derivation]s produced by
|
||||
[`nix-instantiate`](./nix-instantiate.md):
|
||||
|
||||
[store derivation]: ../glossary.md#gloss-store-derivation
|
||||
|
||||
```console
|
||||
$ nix-store -r $(nix-instantiate ./test.nix)
|
||||
/nix/store/31axcgrlbfsxzmfff1gyj1bf62hvkby2-aterm-2.3.1
|
||||
```
|
||||
|
||||
This is essentially what [`nix-build`](nix-build.md) does.
|
||||
|
||||
To test whether a previously-built derivation is deterministic:
|
||||
|
||||
```console
|
||||
$ nix-build '<nixpkgs>' -A hello --check -K
|
||||
```
|
||||
|
||||
Use [`--read-log`](#operation---read-log) to show the stderr and stdout of a build:
|
||||
|
||||
```console
|
||||
$ nix-store --read-log $(nix-instantiate ./test.nix)
|
||||
```

||||
|
||||
# Operation `--serve`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--serve` [`--write`]
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--serve` provides access to the Nix store over stdin and
|
||||
stdout, and is intended to be used as a means of providing Nix store
|
||||
access to a restricted ssh user.
|
||||
|
||||
The following flags are available:
|
||||
|
||||
- `--write`\
|
||||
Allow the connected client to request the realization of
|
||||
derivations. In effect, this can be used to make the host act as a
|
||||
remote builder.
|
||||
|
||||
## Examples
|
||||
|
||||
To turn a host into a build server, the `authorized_keys` file can be
|
||||
used to provide build access to a given SSH public key:
|
||||
|
||||
```console
|
||||
$ cat <<EOF >>/root/.ssh/authorized_keys
|
||||
command="nice -n20 nix-store --serve --write" ssh-rsa AAAAB3NzaC1yc2EAAAA...
|
||||
EOF
|
||||
```
|
||||
|
||||
# Operation `--gc`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--gc` [`--print-roots` | `--print-live` | `--print-dead`] [`--max-freed` *bytes*]
|
||||
|
||||
## Description
|
||||
|
||||
Without additional flags, the operation `--gc` performs a garbage
|
||||
collection on the Nix store. That is, all paths in the Nix store not
|
||||
reachable via file system references from a set of “roots”, are deleted.
|
||||
|
||||
The following suboperations may be specified:
|
||||
|
||||
- `--print-roots`\
|
||||
This operation prints on standard output the set of roots used by
|
||||
the garbage collector.
|
||||
|
||||
- `--print-live`\
|
||||
This operation prints on standard output the set of “live” store
|
||||
paths, which are all the store paths reachable from the roots. Live
|
||||
paths should never be deleted, since that would break consistency —
|
||||
it would become possible that applications are installed that
|
||||
reference things that are no longer present in the store.
|
||||
|
||||
- `--print-dead`\
|
||||
This operation prints out on standard output the set of “dead” store
|
||||
paths, which is just the opposite of the set of live paths: any path
|
||||
in the store that is not live (with respect to the roots) is dead.
|
||||
|
||||
By default, all unreachable paths are deleted. The following options
|
||||
control what gets deleted and in what order:
|
||||
|
||||
- `--max-freed` *bytes*\
|
||||
Keep deleting paths until at least *bytes* bytes have been deleted,
|
||||
then stop. The argument *bytes* can be followed by the
|
||||
multiplicative suffix `K`, `M`, `G` or `T`, denoting KiB, MiB, GiB
|
||||
or TiB units.
|
||||
|
||||
The behaviour of the collector is also influenced by the
|
||||
`keep-outputs` and `keep-derivations` settings in the Nix
|
||||
configuration file.
|
||||
|
||||
By default, the collector prints the total number of freed bytes when it
|
||||
finishes (or when it is interrupted). With `--print-dead`, it prints the
|
||||
number of bytes that would be freed.
|
||||
|
||||
## Examples
|
||||
|
||||
To delete all unreachable paths, just do:
|
||||
|
||||
```console
|
||||
$ nix-store --gc
|
||||
deleting `/nix/store/kq82idx6g0nyzsp2s14gfsc38npai7lf-cairo-1.0.4.tar.gz.drv'
|
||||
...
|
||||
8825586 bytes freed (8.42 MiB)
|
||||
```
|
||||
|
||||
To delete at least 100 MiBs of unreachable paths:
|
||||
|
||||
```console
|
||||
$ nix-store --gc --max-freed $((100 * 1024 * 1024))
|
||||
```
|
||||
|
||||
# Operation `--delete`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--delete` [`--ignore-liveness`] *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--delete` deletes the store paths *paths* from the Nix
|
||||
store, but only if it is safe to do so; that is, when the path is not
|
||||
reachable from a root of the garbage collector. This means that you can
|
||||
only delete paths that would also be deleted by `nix-store --gc`. Thus,
|
||||
`--delete` is a more targeted version of `--gc`.
|
||||
|
||||
With the option `--ignore-liveness`, reachability from the roots is
|
||||
ignored. However, the path still won’t be deleted if there are other
|
||||
paths in the store that refer to it (i.e., depend on it).
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --delete /nix/store/zq0h41l75vlb4z45kzgjjmsjxvcv1qk7-mesa-6.4
|
||||
0 bytes freed (0.00 MiB)
|
||||
error: cannot delete path `/nix/store/zq0h41l75vlb4z45kzgjjmsjxvcv1qk7-mesa-6.4' since it is still alive
|
||||
```

specified. The default query is `--outputs`.
|
||||
|
||||
The paths *paths* may also be symlinks from outside of the Nix store, to
|
||||
the Nix store. In that case, the query is applied to the target of the
|
||||
symlink.
|
||||
|
||||
## Common query options
|
||||
|
||||
- `--use-output`; `-u`\
|
||||
For each argument to the query that is a [store derivation], apply the
|
||||
query to the output path of the derivation instead.
|
||||
|
||||
- `--force-realise`; `-f`\
|
||||
Realise each argument to the query first (see [`nix-store
|
||||
--realise`](#operation---realise)).
|
||||
|
||||
## Queries
|
||||
|
||||
- `--outputs`\
|
||||
Prints out the [output path]s of the store
|
||||
derivations *paths*. These are the paths that will be produced when
|
||||
the derivation is built.
|
||||
|
||||
- `--requisites`; `-R`\
|
||||
Prints out the [closure] of the given *paths*.
|
||||
|
||||
This query has one option:
|
||||
|
||||
- `--include-outputs`
|
||||
Also include the existing output paths of [store derivation]s,
|
||||
and their closures.
|
||||
|
||||
This query can be used to implement various kinds of deployment. A
|
||||
*source deployment* is obtained by distributing the closure of a
|
||||
store derivation. A *binary deployment* is obtained by distributing
|
||||
the closure of an output path. A *cache deployment* (combined
|
||||
source/binary deployment, including binaries of build-time-only
|
||||
dependencies) is obtained by distributing the closure of a store
|
||||
derivation and specifying the option `--include-outputs`.
|
||||
|
||||
- `--references`\
|
||||
Prints the set of [references]s of the store paths
|
||||
*paths*, that is, their immediate dependencies. (For *all*
|
||||
dependencies, use `--requisites`.)
|
||||
|
||||
[reference]: ../glossary.md#gloss-reference
|
||||
|
||||
- `--referrers`\
|
||||
Prints the set of *referrers* of the store paths *paths*, that is,
|
||||
the store paths currently existing in the Nix store that refer to
|
||||
one of *paths*. Note that contrary to the references, the set of
|
||||
referrers is not constant; it can change as store paths are added or
|
||||
removed.
|
||||
|
||||
- `--referrers-closure`\
|
||||
Prints the closure of the set of store paths *paths* under the
|
||||
referrers relation; that is, all store paths that directly or
|
||||
indirectly refer to one of *paths*. These are all the path currently
|
||||
in the Nix store that are dependent on *paths*.
|
||||
|
||||
- `--deriver`; `-d`\
|
||||
Prints the [deriver] of the store paths *paths*. If
|
||||
the path has no deriver (e.g., if it is a source file), or if the
|
||||
deriver is not known (e.g., in the case of a binary-only
|
||||
deployment), the string `unknown-deriver` is printed.
|
||||
|
||||
[deriver]: ../glossary.md#gloss-deriver
|
||||
|
||||
- `--graph`\
|
||||
Prints the references graph of the store paths *paths* in the format
|
||||
of the `dot` tool of AT\&T's [Graphviz
|
||||
package](http://www.graphviz.org/). This can be used to visualise
|
||||
dependency graphs. To obtain a build-time dependency graph, apply
|
||||
this to a store derivation. To obtain a runtime dependency graph,
|
||||
apply it to an output path.
|
||||
|
||||
- `--tree`\
|
||||
Prints the references graph of the store paths *paths* as a nested
|
||||
ASCII tree. References are ordered by descending closure size; this
|
||||
tends to flatten the tree, making it more readable. The query only
|
||||
recurses into a store path when it is first encountered; this
|
||||
prevents a blowup of the tree representation of the graph.
|
||||
|
||||
- `--graphml`\
|
||||
Prints the references graph of the store paths *paths* in the
|
||||
[GraphML](http://graphml.graphdrawing.org/) file format. This can be
|
||||
used to visualise dependency graphs. To obtain a build-time
|
||||
dependency graph, apply this to a [store derivation]. To obtain a
|
||||
runtime dependency graph, apply it to an output path.
|
||||
|
||||
- `--binding` *name*; `-b` *name*\
|
||||
Prints the value of the attribute *name* (i.e., environment
|
||||
variable) of the [store derivation]s *paths*. It is an error for a
|
||||
derivation to not have the specified attribute.
|
||||
|
||||
- `--hash`\
|
||||
Prints the SHA-256 hash of the contents of the store paths *paths*
|
||||
(that is, the hash of the output of `nix-store --dump` on the given
|
||||
paths). Since the hash is stored in the Nix database, this is a fast
|
||||
operation.
|
||||
|
||||
- `--size`\
|
||||
Prints the size in bytes of the contents of the store paths *paths*
|
||||
— to be precise, the size of the output of `nix-store --dump` on
|
||||
the given paths. Note that the actual disk space required by the
|
||||
store paths may be higher, especially on filesystems with large
|
||||
cluster sizes.
|
||||
|
||||
- `--roots`\
|
||||
Prints the garbage collector roots that point, directly or
|
||||
indirectly, at the store paths *paths*.
|
||||
|
||||
## Examples
|
||||
|
||||
Print the closure (runtime dependencies) of the `svn` program in the
|
||||
current user environment:
|
||||
|
||||
```console
|
||||
$ nix-store -qR $(which svn)
|
||||
/nix/store/5mbglq5ldqld8sj57273aljwkfvj22mc-subversion-1.1.4
|
||||
/nix/store/9lz9yc6zgmc0vlqmn2ipcpkjlmbi51vv-glibc-2.3.4
|
||||
...
|
||||
```
|
||||
|
||||
Print the build-time dependencies of `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -qR $(nix-store -qd $(which svn))
|
||||
/nix/store/02iizgn86m42q905rddvg4ja975bk2i4-grep-2.5.1.tar.bz2.drv
|
||||
/nix/store/07a2bzxmzwz5hp58nf03pahrv2ygwgs3-gcc-wrapper.sh
|
||||
/nix/store/0ma7c9wsbaxahwwl04gbw3fcd806ski4-glibc-2.3.4.drv
|
||||
... lots of other paths ...
|
||||
```
|
||||
|
||||
The difference with the previous example is that we ask the closure of
|
||||
the derivation (`-qd`), not the closure of the output path that contains
|
||||
`svn`.
|
||||
|
||||
Show the build-time dependencies as a tree:
|
||||
|
||||
```console
|
||||
$ nix-store -q --tree $(nix-store -qd $(which svn))
|
||||
/nix/store/7i5082kfb6yjbqdbiwdhhza0am2xvh6c-subversion-1.1.4.drv
|
||||
+---/nix/store/d8afh10z72n8l1cr5w42366abiblgn54-builder.sh

|
||||
...
|
||||
```
|
||||
|
||||
Show all paths that depend on the same OpenSSL library as `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --referrers $(nix-store -q --binding openssl $(nix-store -qd $(which svn)))
|
||||
/nix/store/23ny9l9wixx21632y2wi4p585qhva1q8-sylpheed-1.0.0
|
||||
/nix/store/5mbglq5ldqld8sj57273aljwkfvj22mc-subversion-1.1.4
|
||||
/nix/store/dpmvp969yhdqs7lm2r1a3gng7pyq6vy4-subversion-1.1.3
|
||||
/nix/store/l51240xqsgg8a7yrbqdx1rfzyv6l26fx-lynx-2.8.5
|
||||
```
|
||||
|
||||
Show all paths that directly or indirectly depend on the Glibc (C
|
||||
library) used by `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --referrers-closure $(ldd $(which svn) | grep /libc.so | awk '{print $3}')
|
||||
/nix/store/034a6h4vpz9kds5r6kzb9lhh81mscw43-libgnomeprintui-2.8.2
|
||||
/nix/store/15l3yi0d45prm7a82pcrknxdh6nzmxza-gawk-3.1.4
|
||||
...
|
||||
```
|
||||
|
||||
Note that `ldd` is a command that prints out the dynamic libraries used
|
||||
by an ELF executable.
|
||||
|
||||
Make a picture of the runtime dependency graph of the current user
|
||||
environment:
|
||||
|
||||
```console
|
||||
$ nix-store -q --graph ~/.nix-profile | dot -Tps > graph.ps
|
||||
$ gv graph.ps
|
||||
```
|
||||
|
||||
Show every garbage collector root that points to a store path that
|
||||
depends on `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --roots $(which svn)
|
||||
/nix/var/nix/profiles/default-81-link
|
||||
/nix/var/nix/profiles/default-82-link
|
||||
/nix/var/nix/profiles/per-user/eelco/profile-97-link
|
||||
```

# Operation `--add`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--add` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--add` adds the specified paths to the Nix store. It
|
||||
prints the resulting paths in the Nix store on standard output.
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --add ./foo.c
|
||||
/nix/store/m7lrha58ph6rcnv109yzx1nk1cj7k7zf-foo.c
|
||||
```
|
||||
|
||||
# Operation `--add-fixed`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--add-fixed` [`--recursive`] *algorithm* *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--add-fixed` adds the specified paths to the Nix store.
|
||||
Unlike `--add` paths are registered using the specified hashing
|
||||
algorithm, resulting in the same output path as a fixed-output
|
||||
derivation. This can be used for sources that are not available from a
|
||||
public url or broke since the download expression was written.
|
||||
|
||||
This operation has the following options:
|
||||
|
||||
- `--recursive`\
|
||||
Use recursive instead of flat hashing mode, used when adding
|
||||
directories to the store.
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --add-fixed sha256 ./hello-2.10.tar.gz
|
||||
/nix/store/3x7dwzq014bblazs7kq20p9hyzz0qh8g-hello-2.10.tar.gz
|
||||
```
|
||||
|
||||
# Operation `--verify`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--verify` [`--check-contents`] [`--repair`]
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--verify` verifies the internal consistency of the Nix
|
||||
database, and the consistency between the Nix database and the Nix
|
||||
store. Any inconsistencies encountered are automatically repaired.
|
||||
Inconsistencies are generally the result of the Nix store or database
|
||||
being modified by non-Nix tools, or of bugs in Nix itself.
|
||||
|
||||
This operation has the following options:
|
||||
|
||||
- `--check-contents`\
|
||||
Checks that the contents of every valid store path has not been
|
||||
altered by computing a SHA-256 hash of the contents and comparing it
|
||||
with the hash stored in the Nix database at build time. Paths that
|
||||
have been modified are printed out. For large stores,
|
||||
`--check-contents` is obviously quite slow.
|
||||
|
||||
- `--repair`\
|
||||
If any valid path is missing from the store, or (if
|
||||
`--check-contents` is given) the contents of a valid path has been
|
||||
modified, then try to repair the path by redownloading it. See
|
||||
`nix-store --repair-path` for details.
|
||||
|
||||
# Operation `--verify-path`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--verify-path` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--verify-path` compares the contents of the given store
|
||||
paths to their cryptographic hashes stored in Nix’s database. For every
|
||||
changed path, it prints a warning message. The exit status is 0 if no
|
||||
path has changed, and 1 otherwise.
|
||||
|
||||
## Example
|
||||
|
||||
To verify the integrity of the `svn` command and all its dependencies:
|
||||
|
||||
```console
|
||||
$ nix-store --verify-path $(nix-store -qR $(which svn))
|
||||
```
|
||||
|
||||
# Operation `--repair-path`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--repair-path` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--repair-path` attempts to “repair” the specified paths
|
||||
by redownloading them using the available substituters. If no
|
||||
substitutes are available, then repair is not possible.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> During repair, there is a very small time window during which the old
|
||||
> path (if it exists) is moved out of the way and replaced with the new
|
||||
> path. If repair is interrupted in between, then the system may be left
|
||||
> in a broken state (e.g., if the path contains a critical system
|
||||
> component like the GNU C Library).
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --verify-path /nix/store/dj7a81wsm1ijwwpkks3725661h3263p5-glibc-2.13
|
||||

|

# Operation `--dump`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--dump` *path*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--dump` produces a NAR (Nix ARchive) file containing the
|
||||
contents of the file system tree rooted at *path*. The archive is
|
||||
written to standard output.
|
||||
|
||||
A NAR archive is like a TAR or Zip archive, but it contains only the
|
||||
information that Nix considers important. For instance, timestamps are
|
||||
elided because all files in the Nix store have their timestamp set to 1
|
||||
anyway. Likewise, all permissions are left out except for the execute
|
||||
bit, because all files in the Nix store have 444 or 555 permission.
|
||||
|
||||
Also, a NAR archive is *canonical*, meaning that “equal” paths always
|
||||
produce the same NAR archive. For instance, directory entries are
|
||||
always sorted so that the actual on-disk order doesn’t influence the
|
||||
result. This means that the cryptographic hash of a NAR dump of a
|
||||
path is usable as a fingerprint of the contents of the path. Indeed,
|
||||
the hashes of store paths stored in Nix’s database (see `nix-store -q
|
||||
--hash`) are SHA-256 hashes of the NAR dump of each store path.
|
||||
|
||||
NAR archives support filenames of unlimited length and 64-bit file
|
||||
sizes. They can contain regular files, directories, and symbolic links,
|
||||
but not other types of files (such as device nodes).
|
||||
|
||||
A Nix archive can be unpacked using `nix-store
|
||||
--restore`.
|
||||
|
||||
# Operation `--restore`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--restore` *path*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--restore` unpacks a NAR archive to *path*, which must
|
||||
not already exist. The archive is read from standard input.
|
||||
|
||||
# Operation `--export`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--export` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--export` writes a serialisation of the specified store
|
||||
paths to standard output in a format that can be imported into another
|
||||
Nix store with `nix-store --import`. This is like `nix-store
|
||||
--dump`, except that the NAR archive produced by that command doesn’t
|
||||
contain the necessary meta-information to allow it to be imported into
|
||||
another Nix store (namely, the set of references of the path).
|
||||
|
||||
This command does not produce a *closure* of the specified paths, so if
|
||||
a store path references other store paths that are missing in the target
|
||||
Nix store, the import will fail. To copy a whole closure, do something
|
||||
like:
|
||||
|
||||
```console
|
||||
$ nix-store --export $(nix-store -qR paths) > out
|
||||
```
|
||||
|
||||
To import the whole closure again, run:
|
||||
|
||||
```console
|
||||
$ nix-store --import < out
|
||||
```
|
||||
|
||||
# Operation `--import`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--import`
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--import` reads a serialisation of a set of store paths
|
||||
produced by `nix-store --export` from standard input and adds those
|
||||
store paths to the Nix store. Paths that already exist in the Nix store
|
||||
are ignored. If a path refers to another path that doesn’t exist in the
|
||||
Nix store, the import fails.
|
||||
|
||||
# Operation `--optimise`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--optimise`
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--optimise` reduces Nix store disk space usage by finding
|
||||
identical files in the store and hard-linking them to each other. It
|
||||
typically reduces the size of the store by something like 25-35%. Only
|
||||
regular files and symlinks are hard-linked in this manner. Files are
|
||||
considered identical when they have the same NAR archive serialisation:
|
||||
that is, regular files must have the same contents and permission
|
||||
(executable or non-executable), and symlinks must have the same
|
||||
contents.
|
||||
|
||||
After completion, or when the command is interrupted, a report on the
|
||||
achieved savings is printed on standard error.
|
||||
|
||||
Use `-vv` or `-vvv` to get some progress indication.
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --optimise
|
||||
hashing files in `/nix/store/qhqx7l2f1kmwihc9bnxs7rc159hsxnf3-gcc-4.1.1'
|
||||
...
|
||||
541838819 bytes (516.74 MiB) freed by hard-linking 54143 files;
|
||||
there are 114486 files with equal contents out of 215894 files in total
|
||||
```
|
||||
|
||||
# Operation `--read-log`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` {`--read-log` | `-l`} *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--read-log` prints the build log of the specified store
|
||||
paths on standard output. The build log is whatever the builder of a
|
||||
derivation wrote to standard output and standard error. If a store path
|
||||
is not a derivation, the deriver of the store path is used.
|
||||
|
||||
Build logs are kept in `/nix/var/log/nix/drvs`. However, there is no
|
||||
guarantee that a build log is available for any particular store path.
|
||||
For instance, if the path was downloaded as a pre-built binary through a
|
||||
substitute, then the log is unavailable.
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store -l $(which ktorrent)
|
||||
building /nix/store/dhc73pvzpnzxhdgpimsd9sw39di66ph1-ktorrent-2.2.1

# Operation `--dump-db`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--dump-db` [*paths…*]
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--dump-db` writes a dump of the Nix database to standard
|
||||
output. It can be loaded into an empty Nix store using `--load-db`. This
|
||||
is useful for making backups and when migrating to different database
|
||||
schemas.
|
||||
|
||||
By default, `--dump-db` will dump the entire Nix database. When one or
|
||||
more store paths is passed, only the subset of the Nix database for
|
||||
those store paths is dumped. As with `--export`, the user is responsible
|
||||
for passing all the store paths for a closure. See `--export` for an
|
||||
example.
|
||||
|
||||
# Operation `--load-db`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--load-db`
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--load-db` reads a dump of the Nix database created by
|
||||
`--dump-db` from standard input and loads it into the Nix database.
|
||||
|
||||
# Operation `--print-env`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--print-env` *drvpath*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--print-env` prints out the environment of a derivation
|
||||
in a format that can be evaluated by a shell. The command line arguments
|
||||
of the builder are placed in the variable `_args`.
|
||||
|
||||
## Example
|
||||
|
||||
```console
|
||||
$ nix-store --print-env $(nix-instantiate '<nixpkgs>' -A firefox)
|
||||
…
|
||||
export src; src='/nix/store/plpj7qrwcz94z2psh6fchsi7s8yihc7k-firefox-12.0.source.tar.bz2'
|
||||
export stdenv; stdenv='/nix/store/7c8asx3yfrg5dg1gzhzyq2236zfgibnn-stdenv'
|
||||
export system; system='x86_64-linux'
|
||||
export _args; _args='-e /nix/store/9krlzvny65gdc8s7kpb6lkx8cd02c25c-default-builder.sh'

# Operation `--generate-binary-cache-key`
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--generate-binary-cache-key` *key-name* *secret-key-file* *public-key-file*
|
||||
|
||||
## Description
|
||||
|
||||
This command generates an [Ed25519 key pair](http://ed25519.cr.yp.to/)
|
||||
that can be used to create a signed binary cache. It takes three
|
||||
mandatory parameters:
|
||||
|
||||
1. A key name, such as `cache.example.org-1`, that is used to look up
|
||||
keys on the client when it verifies signatures. It can be anything,
|
||||
but it’s suggested to use the host name of your cache (e.g.
|
||||
`cache.example.org`) with a suffix denoting the number of the key
|
||||
(to be incremented every time you need to revoke a key).
|
||||
|
||||
2. The file name where the secret key is to be stored.
|
||||
|
||||
3. The file name where the public key is to be stored.
|
||||
`nix-store` takes exactly one *operation* flag which indicates the subcommand to be performed. The following operations are available:
|
||||
|
||||
- [`--realise`](./nix-store/realise.md)
|

`nix-store --add-fixed` - add paths to store using given hashing algorithm
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--add-fixed` [`--recursive`] *algorithm* *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--add-fixed` adds the specified paths to the Nix store.
|
||||
Unlike `--add` paths are registered using the specified hashing
|
||||
algorithm, resulting in the same output path as a fixed-output
|
||||
derivation. This can be used for sources that are not available from a
|
||||
public url or broke since the download expression was written.
|
||||
|
||||
This operation has the following options:
|
||||
|
||||
- `--recursive`\
|
||||
Use recursive instead of flat hashing mode, used when adding
|
||||
directories to the store.

# Synopsis

|

`nix-store` `--delete` [`--ignore-liveness`] *paths…*
|
||||
|
||||
# Description
|
||||
|
||||
The operation `--delete` deletes the store paths *paths* from the Nix
|
||||
store, but only if it is safe to do so; that is, when the path is not
|
||||
reachable from a root of the garbage collector. This means that you can
|
||||
only delete paths that would also be deleted by `nix-store --gc`. Thus,
|
||||
`--delete` is a more targeted version of `--gc`.
|
||||
|
||||
With the option `--ignore-liveness`, reachability from the roots is
|
||||
ignored. However, the path still won’t be deleted if there are other
|
||||
paths in the store that refer to it (i.e., depend on it).

# Name
|
||||
|
||||
`nix-store --dump` - write a single path to a Nix Archive
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--dump` *path*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--dump` produces a NAR (Nix ARchive) file containing the
|
||||
contents of the file system tree rooted at *path*. The archive is
|
||||
written to standard output.
|
||||
|
||||
A NAR archive is like a TAR or Zip archive, but it contains only the
|
||||
information that Nix considers important. For instance, timestamps are
|
||||
elided because all files in the Nix store have their timestamp set to 0
|
||||
anyway. Likewise, all permissions are left out except for the execute
|
||||
bit, because all files in the Nix store have 444 or 555 permission.
|
||||
|
||||
Also, a NAR archive is *canonical*, meaning that “equal” paths always
|
||||
produce the same NAR archive. For instance, directory entries are
|
||||
always sorted so that the actual on-disk order doesn’t influence the
|
||||
result. This means that the cryptographic hash of a NAR dump of a
|
||||
path is usable as a fingerprint of the contents of the path. Indeed,
|
||||
the hashes of store paths stored in Nix’s database (see `nix-store -q
|
||||
--hash`) are SHA-256 hashes of the NAR dump of each store path.
|
||||
|
||||
NAR archives support filenames of unlimited length and 64-bit file
|
||||
sizes. They can contain regular files, directories, and symbolic links,
|
||||
but not other types of files (such as device nodes).
|
||||
|
||||
A Nix archive can be unpacked using `nix-store
|
||||
--restore`.

`nix-store --export` - export store paths to a Nix Archive
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--export` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--export` writes a serialisation of the specified store
|
||||
paths to standard output in a format that can be imported into another
|
||||
Nix store with `nix-store --import`. This is like `nix-store
|
||||
--dump`, except that the NAR archive produced by that command doesn’t
|
||||
contain the necessary meta-information to allow it to be imported into
|
||||
another Nix store (namely, the set of references of the path).
|
||||
|
||||
This command does not produce a *closure* of the specified paths, so if
|
||||
a store path references other store paths that are missing in the target
|
||||
Nix store, the import will fail.

|

$ nix-store --import < out

`nix-store --gc` - run garbage collection
|

|
||||
# Synopsis
|
||||
|
||||
`nix-store` `--gc` [`--print-roots` | `--print-live` | `--print-dead`] [`--max-freed` *bytes*]
|
||||
|
||||
# Description
|
||||
|
||||
Without additional flags, the operation `--gc` performs a garbage
|
||||
collection on the Nix store. That is, all paths in the Nix store not
|
||||
reachable via file system references from a set of “roots”, are deleted.
|
||||
|
||||
The following suboperations may be specified:
|
||||
|
||||
- `--print-roots`\
|
||||
This operation prints on standard output the set of roots used by
|
||||
the garbage collector.
|
||||
|
||||
- `--print-live`\
|
||||
This operation prints on standard output the set of “live” store
|
||||
paths, which are all the store paths reachable from the roots. Live
|
||||
paths should never be deleted, since that would break consistency —
|
||||
it would become possible that applications are installed that
|
||||
reference things that are no longer present in the store.
|
||||
|
||||
- `--print-dead`\
|
||||
This operation prints out on standard output the set of “dead” store
|
||||
paths, which is just the opposite of the set of live paths: any path
|
||||
in the store that is not live (with respect to the roots) is dead.
|
||||
|
||||
By default, all unreachable paths are deleted. The following options
|
||||
control what gets deleted and in what order:
|
||||
|
||||
- `--max-freed` *bytes*\
|
||||
Keep deleting paths until at least *bytes* bytes have been deleted,
|
||||
then stop. The argument *bytes* can be followed by the
|
||||
multiplicative suffix `K`, `M`, `G` or `T`, denoting KiB, MiB, GiB
|
||||
or TiB units.
|
||||
|
||||
The behaviour of the collector is also influenced by the
|
||||
`keep-outputs` and `keep-derivations` settings in the Nix
|
||||
configuration file.
|
||||
|
||||
By default, the collector prints the total number of freed bytes when it
|
||||
finishes (or when it is interrupted). With `--print-dead`, it prints the
|
||||
number of bytes that would be freed.

|
||||

# Examples
|

To delete all unreachable paths, just do:

```console

deleting `/nix/store/kq82idx6g0nyzsp2s14gfsc38npai7lf-cairo-1.0.4.tar.gz.drv'
|

...
|

8825586 bytes freed (8.42 MiB)
|
||||
```
|
||||
|
||||
To delete at least 100 MiBs of unreachable paths:
|
||||
|
||||
```console
|
||||
$ nix-store --gc --max-freed $((100 * 1024 * 1024))

# Options
|
||||
|
||||
The following options are allowed for all `nix-store` operations, but may not always have an effect.
|
||||
|
||||
- <span id="opt-add-root">[`--add-root`](#opt-add-root)</span> *path*
|
||||
|
||||
Causes the result of a realisation (`--realise` and
|
||||
`--force-realise`) to be registered as a root of the garbage
|
||||
collector. *path* will be created as a symlink to the resulting
|
||||
store path. In addition, a uniquely named symlink to *path* will
|
||||
be created in `/nix/var/nix/gcroots/auto/`. For instance,
|
||||
|
||||
```console
|
||||
$ nix-store --add-root /home/eelco/bla/result -r ...
|
||||
|
||||
$ ls -l /nix/var/nix/gcroots/auto
|
||||
lrwxrwxrwx 1 ... 2005-03-13 21:10 dn54lcypm8f8... -> /home/eelco/bla/result
|
||||
|
||||
$ ls -l /home/eelco/bla/result
|
||||
lrwxrwxrwx 1 ... 2005-03-13 21:10 /home/eelco/bla/result -> /nix/store/1r11343n6qd4...-f-spot-0.0.10
|
||||
```
|
||||
|
||||
Thus, when `/home/eelco/bla/result` is removed, the GC root in the
|
||||
`auto` directory becomes a dangling symlink and will be ignored by
|
||||
the collector.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> Note that it is not possible to move or rename GC roots, since
|
||||
> the symlink in the `auto` directory will still point to the old
|
||||
> location.
|
||||
|
||||
If there are multiple results, then multiple symlinks will be
|
||||
created by sequentially numbering symlinks beyond the first one
|
||||
(e.g., `foo`, `foo-2`, `foo-3`, and so on).

# Name

`nix-store --optimise` - reduce disk space usage
|
||||
|
||||
## Synopsis
|
||||
|
||||
`nix-store` `--optimise`
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--optimise` reduces Nix store disk space usage by finding
|
||||
identical files in the store and hard-linking them to each other. It
|
||||
typically reduces the size of the store by something like 25-35%. Only
|
||||
regular files and symlinks are hard-linked in this manner. Files are
|
||||
considered identical when they have the same NAR archive serialisation:
|
||||
that is, regular files must have the same contents and permission
|
||||
(executable or non-executable), and symlinks must have the same
|
||||
contents.
|
||||
|
||||
After completion, or when the command is interrupted, a report on the
|
||||
achieved savings is printed on standard error.
|
||||
|
||||
Use `-vv` or `-vvv` to get some progress indication.

|

|
||||
# Description
|
||||
|
||||
The operation `--query` displays various bits of information about the
|
||||
store paths . The queries are described below. At most one query can be
|
||||
specified. The default query is `--outputs`.
|
||||
|
||||
The paths *paths* may also be symlinks from outside of the Nix store, to
|
||||
the Nix store. In that case, the query is applied to the target of the
|
||||
symlink.
|
||||
|
||||
# Common query options
|
||||
|
||||
- `--use-output`; `-u`\
|
||||
For each argument to the query that is a [store derivation], apply the
|
||||
query to the output path of the derivation instead.
|
||||
|
||||
- `--force-realise`; `-f`\
|
||||
Realise each argument to the query first (see [`nix-store --realise`](./realise.md)).
|
||||
|
||||
[store derivation]: @docroot@/glossary.md#gloss-store-derivation
|
||||
|
||||
# Queries
|
||||
|
||||
- `--outputs`\
|
||||
Prints out the [output paths] of the store
|
||||
derivations *paths*. These are the paths that will be produced when
|
||||
the derivation is built.
|
||||
|
||||
[output paths]: ../../glossary.md#gloss-output-path
|
||||
|
||||
- `--requisites`; `-R`\
|
||||
Prints out the [closure] of the store path *paths*.
|
||||
|
||||
[closure]: ../../glossary.md#gloss-closure
|
||||
|
||||
This query has one option:
|
||||
|
||||
- `--include-outputs`
|
||||
Also include the existing output paths of [store derivation]s,
|
||||
and their closures.
|
||||
|
||||
This query can be used to implement various kinds of deployment. A
|
||||
*source deployment* is obtained by distributing the closure of a
|
||||
store derivation. A *binary deployment* is obtained by distributing
|
||||
the closure of an output path. A *cache deployment* (combined
|
||||
source/binary deployment, including binaries of build-time-only
|
||||
dependencies) is obtained by distributing the closure of a store
|
||||
derivation and specifying the option `--include-outputs`.
|
||||
|
||||
- `--references`\
|
||||
Prints the set of [references] of the store paths
|
||||
*paths*, that is, their immediate dependencies. (For *all*
|
||||
dependencies, use `--requisites`.)
|
||||
|
||||
[references]: ../../glossary.md#gloss-reference
|
||||
|
||||
- `--referrers`\
|
||||
Prints the set of *referrers* of the store paths *paths*, that is,
|
||||
the store paths currently existing in the Nix store that refer to
|
||||
one of *paths*. Note that contrary to the references, the set of
|
||||
referrers is not constant; it can change as store paths are added or
|
||||
removed.
|
||||
|
||||
- `--referrers-closure`\
|
||||
Prints the closure of the set of store paths *paths* under the
|
||||
referrers relation; that is, all store paths that directly or
|
||||
indirectly refer to one of *paths*. These are all the path currently
|
||||
in the Nix store that are dependent on *paths*.
|
||||
|
||||
- `--deriver`; `-d`\
|
||||
Prints the [deriver] of the store paths *paths*. If
|
||||
the path has no deriver (e.g., if it is a source file), or if the
|
||||
deriver is not known (e.g., in the case of a binary-only
|
||||
deployment), the string `unknown-deriver` is printed.
|
||||
|
||||
[deriver]: ../../glossary.md#gloss-deriver
|
||||
|
||||
- `--graph`\
|
||||
Prints the references graph of the store paths *paths* in the format
|
||||
of the `dot` tool of AT\&T's [Graphviz
|
||||
package](http://www.graphviz.org/). This can be used to visualise
|
||||
dependency graphs. To obtain a build-time dependency graph, apply
|
||||
this to a store derivation. To obtain a runtime dependency graph,
|
||||
apply it to an output path.
|
||||
|
||||
- `--tree`\
|
||||
Prints the references graph of the store paths *paths* as a nested
|
||||
ASCII tree. References are ordered by descending closure size; this
|
||||
tends to flatten the tree, making it more readable. The query only
|
||||
recurses into a store path when it is first encountered; this
|
||||
prevents a blowup of the tree representation of the graph.
|
||||
|
||||
- `--graphml`\
|
||||
Prints the references graph of the store paths *paths* in the
|
||||
[GraphML](http://graphml.graphdrawing.org/) file format. This can be
|
||||
used to visualise dependency graphs. To obtain a build-time
|
||||
dependency graph, apply this to a [store derivation]. To obtain a
|
||||
runtime dependency graph, apply it to an output path.
|
||||
|
||||
- `--binding` *name*; `-b` *name*\
|
||||
Prints the value of the attribute *name* (i.e., environment
|
||||
variable) of the [store derivation]s *paths*. It is an error for a
|
||||
derivation to not have the specified attribute.
|
||||
|
||||
- `--hash`\
|
||||
Prints the SHA-256 hash of the contents of the store paths *paths*
|
||||
(that is, the hash of the output of `nix-store --dump` on the given
|
||||
paths). Since the hash is stored in the Nix database, this is a fast
|
||||
operation.
|
||||
|
||||
- `--size`\
|
||||
Prints the size in bytes of the contents of the store paths *paths*
|
||||
— to be precise, the size of the output of `nix-store --dump` on
|
||||
the given paths. Note that the actual disk space required by the
|
||||
store paths may be higher, especially on filesystems with large
|
||||
cluster sizes.
|
||||
|
||||
- `--roots`\
|
||||
Prints the garbage collector roots that point, directly or
|
||||
indirectly, at the store paths *paths*.

||||

# Examples
|
||||
|
||||
Print the closure (runtime dependencies) of the `svn` program in the
|
||||
current user environment:
|
||||
|
||||
```console
|
||||
$ nix-store -qR $(which svn)
|
||||
/nix/store/5mbglq5ldqld8sj57273aljwkfvj22mc-subversion-1.1.4
|
||||
/nix/store/9lz9yc6zgmc0vlqmn2ipcpkjlmbi51vv-glibc-2.3.4
|
||||
...
|
||||
```
|
||||
|
||||
Print the build-time dependencies of `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -qR $(nix-store -qd $(which svn))
|
||||
/nix/store/02iizgn86m42q905rddvg4ja975bk2i4-grep-2.5.1.tar.bz2.drv
|
||||
/nix/store/07a2bzxmzwz5hp58nf03pahrv2ygwgs3-gcc-wrapper.sh
|
||||
/nix/store/0ma7c9wsbaxahwwl04gbw3fcd806ski4-glibc-2.3.4.drv
|
||||
... lots of other paths ...
|
||||
```
|
||||
|
||||
The difference with the previous example is that we ask the closure of
|
||||
the derivation (`-qd`), not the closure of the output path that contains
|
||||
`svn`.
|
||||
|
||||
Show the build-time dependencies as a tree:
|
||||
|
||||
```console
|
||||
$ nix-store -q --tree $(nix-store -qd $(which svn))
|
||||
/nix/store/7i5082kfb6yjbqdbiwdhhza0am2xvh6c-subversion-1.1.4.drv

|
||||
...
|
||||
```
|
||||
|
||||
Show all paths that depend on the same OpenSSL library as `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --referrers $(nix-store -q --binding openssl $(nix-store -qd $(which svn)))
|
||||

|
||||
/nix/store/l51240xqsgg8a7yrbqdx1rfzyv6l26fx-lynx-2.8.5
|
||||
```
|
||||
|
||||
Show all paths that directly or indirectly depend on the Glibc (C
|
||||
library) used by `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --referrers-closure $(ldd $(which svn) | grep /libc.so | awk '{print $3}')
|
||||
/nix/store/034a6h4vpz9kds5r6kzb9lhh81mscw43-libgnomeprintui-2.8.2
|
||||
/nix/store/15l3yi0d45prm7a82pcrknxdh6nzmxza-gawk-3.1.4
|
||||
...
|
||||
```
|
||||
|
||||
Note that `ldd` is a command that prints out the dynamic libraries used
|
||||
by an ELF executable.
|
||||
|
||||
Make a picture of the runtime dependency graph of the current user
|
||||
environment:
|
||||
|
||||
```console
|
||||
$ nix-store -q --graph ~/.nix-profile | dot -Tps > graph.ps
|
||||
$ gv graph.ps
|
||||
```
|
||||
|
||||
Show every garbage collector root that points to a store path that
|
||||
depends on `svn`:
|
||||
|
||||
```console
|
||||
$ nix-store -q --roots $(which svn)
|
||||
/nix/var/nix/profiles/default-81-link
|

# Description
|
||||
|
||||
The operation `--read-log` prints the build log of the specified store
|
||||
paths on standard output. The build log is whatever the builder of a
|
||||
derivation wrote to standard output and standard error. If a store path
|
||||
is not a derivation, the deriver of the store path is used.
|
||||
|
||||
Build logs are kept in `/nix/var/log/nix/drvs`. However, there is no
|
||||
guarantee that a build log is available for any particular store path.
|
||||
For instance, if the path was downloaded as a pre-built binary through a
|
||||
substitute, then the log is unavailable.

`nix-store --realise` - realise specified store paths
|

|
||||
# Synopsis
|
||||
|
||||
`nix-store` {`--realise` | `-r`} *paths…* [`--dry-run`]
|
||||
|
||||
# Description
|
||||
|
||||
The operation `--realise` essentially “builds” the specified store
|
||||
paths. Realisation is a somewhat overloaded term:
|
||||
|
||||
- If the store path is a *derivation*, realisation ensures that the
|
||||
output paths of the derivation are [valid] (i.e.,
|
||||
the output path and its closure exist in the file system). This
|
||||
can be done in several ways. First, it is possible that the
|
||||
outputs are already valid, in which case we are done
|
||||
immediately. Otherwise, there may be [substitutes]
|
||||
that produce the outputs (e.g., by downloading them). Finally, the
|
||||
outputs can be produced by running the build task described
|
||||
by the derivation.
|
||||
|
||||
- If the store path is not a derivation, realisation ensures that the
|
||||
specified path is valid (i.e., it and its closure exist in the file
|
||||
system). If the path is already valid, we are done immediately.
|
||||
Otherwise, the path and any missing paths in its closure may be
|
||||
produced through substitutes. If there are no (successful)
|
||||
substitutes, realisation fails.
|
||||
|
||||
[valid]: @docroot@/glossary.md#gloss-validity
|
||||
[substitutes]: @docroot@/glossary.md#gloss-substitute
|
||||
|
||||
The output path of each derivation is printed on standard output. (For
|
||||
non-derivations argument, the argument itself is printed.)
|
||||
|
||||
The following flags are available:
|
||||
|
||||
- `--dry-run`\
|
||||
Print on standard error a description of what packages would be
|
||||
built or downloaded, without actually performing the operation.
|
||||
|
||||
- `--ignore-unknown`\
|
||||
If a non-derivation path does not have a substitute, then silently
|
||||
ignore it.
|
||||
|
||||
- `--check`\
|
||||
This option allows you to check whether a derivation is
|
||||
deterministic. It rebuilds the specified derivation and checks
|
||||
whether the result is bitwise-identical with the existing outputs,
|
||||
printing an error if that’s not the case. The outputs of the
|
||||
specified derivation must already exist. When used with `-K`, if an
|
||||
output path is not identical to the corresponding output from the
|
||||
previous build, the new output path is left in
|
||||
`/nix/store/name.check.`
|
||||
|
||||
Special exit codes:
|
||||

# Examples

This operation is typically used to build [store derivation]s produced by
|
||||
[`nix-instantiate`](@docroot@/command-ref/nix-instantiate.md):
|
||||
|
||||
[store derivation]: @docroot@/glossary.md#gloss-store-derivation

/nix/store/31axcgrlbfsxzmfff1gyj1bf62hvkby2-aterm-2.3.1
|
||||
```
|
||||
|
||||
This is essentially what [`nix-build`](@docroot@/command-ref/nix-build.md) does.
|
||||
|
||||
To test whether a previously-built derivation is deterministic:

|
||||
```console

$ nix-build '<nixpkgs>' -A hello --check -K
|
||||
```
|

$ nix-store --read-log $(nix-instantiate ./test.nix)

# Name

|
||||
`nix --repair-path` - re-download path from substituter
|
||||
|
||||
# Synopsis
|
||||
|
||||
`nix-store` `--repair-path` *paths…*
|
||||
|
||||
# Description
|
||||
|
||||
The operation `--repair-path` attempts to “repair” the specified paths
|
||||
by redownloading them using the available substituters. If no
|
||||
substitutes are available, then repair is not possible.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> During repair, there is a very small time window during which the old
|
||||
> path (if it exists) is moved out of the way and replaced with the new
|
||||
> path. If repair is interrupted in between, then the system may be left
|
||||
> in a broken state (e.g., if the path contains a critical system
|
||||
> component like the GNU C Library).

`nix-store` `--serve` [`--write`]
|
||||
|
||||
# Description
|
||||
|
||||
The operation `--serve` provides access to the Nix store over stdin and
|
||||
stdout, and is intended to be used as a means of providing Nix store
|
||||
access to a restricted ssh user.
|
||||
|
||||
The following flags are available:
|
||||
|
||||
- `--write`\
|
||||
Allow the connected client to request the realization of
|
||||
derivations. In effect, this can be used to make the host act as a

# Name

`nix-store --verify` - check Nix database for consistency

|

# Synopsis
|
||||
|
||||
`nix-store` `--verify` [`--check-contents`] [`--repair`]
|
||||
|
||||
# Description
|
||||
|
||||
The operation `--verify` verifies the internal consistency of the Nix
|
||||
database, and the consistency between the Nix database and the Nix
|
||||
store. Any inconsistencies encountered are automatically repaired.
|
||||
Inconsistencies are generally the result of the Nix store or database
|
||||
being modified by non-Nix tools, or of bugs in Nix itself.
|
||||
|
||||
This operation has the following options:
|
||||
|
||||
- `--check-contents`\
|
||||
Checks that the contents of every valid store path has not been
|
||||
altered by computing a SHA-256 hash of the contents and comparing it
|
||||
with the hash stored in the Nix database at build time. Paths that
|
||||
have been modified are printed out. For large stores,
|
||||
`--check-contents` is obviously quite slow.
|
||||
|
||||
- `--repair`\
|
||||
If any valid path is missing from the store, or (if
|
||||
`--check-contents` is given) the contents of a valid path has been
|
||||
modified, then try to repair the path by redownloading it. See
|
||||
`nix-store --repair-path` for details.

# Serving a Nix store via S3

|
||||
Nix has [built-in support](@docroot@/command-ref/new-cli/nix3-help-stores.md#s3-binary-cache-store)
|
||||
for storing and fetching store paths from
|
||||
Amazon S3 and S3-compatible services. This uses the same *binary*
|
||||
cache mechanism that Nix usually uses to fetch prebuilt binaries from
|
||||
[cache.nixos.org](https://cache.nixos.org/).
|
||||
|
||||
The following options can be specified as URL parameters to the S3 URL:
|
||||
|
||||
- `profile`\
|
||||
The name of the AWS configuration profile to use. By default Nix
|
||||
will use the `default` profile.
|
||||
|
||||
- `region`\
|
||||
The region of the S3 bucket. `us–east-1` by default.
|
||||
|
||||
If your bucket is not in `us–east-1`, you should always explicitly
|
||||
specify the region parameter.
|
||||
|
||||
- `endpoint`\
|
||||
The URL to your S3-compatible service, for when not using Amazon S3.
|
||||
Do not specify this value if you're using Amazon S3.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> This endpoint must support HTTPS and will use path-based
|
||||
> addressing instead of virtual host based addressing.
|
||||
|
||||
- `scheme`\
|
||||
The scheme used for S3 requests, `https` (default) or `http`. This
|
||||
option allows you to disable HTTPS for binary caches which don't
|
||||
support it.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> HTTPS should be used if the cache might contain sensitive
|
||||
> information.

||||

* Commands which take installables on the command line can now read them from the standard input if
|
||||
passed the `--stdin` flag. This is primarily useful when you have a large amount of paths which
|
||||
exceed the OS arg limit.
|
||||
|
||||
* The `nix-hash` command now supports Base64 and SRI. Use the flags `--base64`
|
||||
or `--sri` to specify the format of output hash as Base64 or SRI, and `--to-base64`
|
||||
or `--to-sri` to convert a hash to Base64 or SRI format, respectively.
|
||||
|
||||
As the choice of hash formats is no longer binary, the `--base16` flag is also added
|
||||
to explicitly specify the Base16 format, which is still the default.
|
||||
|
||||
* The special handling of an [installable](../command-ref/new-cli/nix.md#installables) with `.drv` suffix being interpreted as all of the given [store derivation](../glossary.md#gloss-store-derivation)'s output paths is removed, and instead taken as the literal store path that it represents.
|
||||
|
||||
The new `^` syntax for store paths introduced in Nix 2.13 allows explicitly referencing output paths of a derivation.
|
||||
Using this is better and more clear than relying on the now-removed `.drv` special handling.
|
||||
|
||||
For example,
|
||||
```shell-session
|
||||
$ nix path-info /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv
|
||||
```
|
||||
|
||||
now gives info about the derivation itself, while
|
||||
|
||||
```shell-session
|
||||
$ nix path-info /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv^*
|
||||
```
|
||||
provides information about each of its outputs.
|
||||
|
||||
* The experimental command `nix describe-stores` has been removed.
|
||||
|
||||
* Nix stores and their settings are now documented in [`nix help-stores`](@docroot@/command-ref/new-cli/nix3-help-stores.md).
|
||||
|
||||
* Documentation for operations of `nix-store` and `nix-env` are now available on separate pages of the manual.
|
||||
They include all common options that can be specified and common environment variables that affect these commands.
|
||||
|
||||
These pages can be viewed offline with `man` using
|
||||
|
||||
* `man nix-store-<operation>` and `man nix-env-<operation>`
|
||||
* `nix-store --help --<operation>` and `nix-env --help --<operation>`.

## Motivation
|
||||
|
||||
The goal of the team is to help other people to contribute to Nix.
|
||||
The team's main responsibility is to set a direction for the development of Nix and ensure that the code is in good shape.
|
||||
|
||||
We aim to achieve this by improving the contributor experience and attracting more maintainers – that is, by helping other people contributing to Nix and eventually taking responsibility – in order to scale the development process to match users' needs.
|
||||
|
||||
### Objectives
|
||||
|
||||
- It is obvious what is worthwhile to work on.
|
||||
- It is easy to find the right place in the code to make a change.
|
||||
- It is clear what is expected of a pull request.
|
||||
- It is predictable how to get a change merged and released.
|
||||
|
||||
### Tasks
|
||||
|
||||
- Establish, communicate, and maintain a technical roadmap
|
||||
- Improve documentation targeted at contributors
|
||||
- Record architecture and design decisions
|
||||
- Elaborate contribution guides and abide to them
|
||||
- Define and assert quality criteria for contributions
|
||||
- Maintain the issue tracker and triage pull requests
|
||||
- Help contributors succeed with pull requests that address roadmap milestones
|
||||
- Manage the release lifecycle
|
||||
- Regularly publish reports on work done
|
||||
- Engage with third parties in the interest of the project
|
||||
- Ensure the required maintainer capacity for all of the above
