# 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.

[`--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](../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
|
|
||||||
```

|
|
||||||
## 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.

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`}]
|
|
||||||
[`--system`]
|
|
||||||
[`--drv-path`]
|
|
||||||
[`--out-path`]
|
|
||||||
[`--description`]
|
|
||||||
[`--meta`]
|
|
||||||
[`--xml`]
|
|
||||||
[`--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`.
|
|
||||||
|

|
|
||||||
|
|
||||||
This operation print a list of all the currently existing generations
|
|
||||||
for the active profile. These may be switched to using the
|
|
||||||
`--switch-generation` operation. It also prints the creation date of the
|
|
||||||
generation, and indicates the current generation.
|
|
||||||
|
|
||||||
## Examples
|
|
||||||
|
|
||||||
```console
|
|
||||||
$ nix-env --list-generations
|
|
||||||

# 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
|
|
||||||
```

`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
|

# 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 --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.

|

|
|

|
# 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
|
||||||

|
## Description
|
||||||
|
|
||||||
|
The `--set` operation modifies the current generation of a profile so
|

|
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.

`nix-env` {`--upgrade` | `-u`} *args*

|
||||||

# 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 collector.

|
|
||||||
|
|
||||||
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
|
|
||||||
```

|
|
||||||
|
|
||||||
## Description
|
|
||||||
|
|
||||||
The operation `--query` displays information about [store path]s.
|
|
||||||
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`](#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))
|
|
||||||

|
|
||||||
... 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))
|
|

|
|
||||||
```
|
|
||||||
|
|
||||||
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}')

|
|
||||||
...
|
|
||||||
```
|
|
||||||
|
|
||||||
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

# 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.
|
|
||||||
|
|
||||||

## 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.

## Description
|
|
||||||
|
|
||||||
The operation `--print-env` prints out the environment of a derivation
|

# Name

||||||
|
|
||||||
|
`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).

# 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.

`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.

{{#include ../env-common.md}}
|
||||||
|
|
||||||
|
# Examples
|
||||||
|
|
||||||
|
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
|
||||||
|

|
`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))

# 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).

`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))
|
||||||
|

|
||||||
|
...
|
||||||
|
```
|
||||||
|
|
||||||
|
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

`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.

`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:
|
||||||
|
|
||||||
|
- `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](@docroot@/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.

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
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ nix-store -r $(nix-instantiate ./test.nix)
|
||||||
|
/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
|
||||||
|
```
|
||||||
|
|
||||||
|
Use [`nix-store --read-log`](./read-log.md) to show the stderr and stdout of a build:
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ nix-store --read-log $(nix-instantiate ./test.nix)
|

`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
|
||||||
|
remote builder.

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
|

`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.

* 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>`.

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
