# Stale bot information
|
||||
|
||||
- Thanks for your contribution!
|
||||
- To remove the stale label, just leave a new comment.
|
||||
- _How to find the right people to ping?_ → [`git blame`](https://git-scm.com/docs/git-blame) to the rescue! (or GitHub's history and blame buttons.)
|
||||
- You can always ask for help on [our Discourse Forum](https://discourse.nixos.org/) or on [Matrix - #nix:nixos.org](https://matrix.to/#/#nix:nixos.org).
|
||||
|
||||
## Suggestions for PRs
|
||||
|
||||
1. GitHub sometimes doesn't notify people who commented / reviewed a PR previously, when you (force) push commits. If you have addressed the reviews you can [officially ask for a review](https://docs.github.com/en/free-pro-team@latest/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from those who commented to you or anyone else.
|
||||
2. If it is unfinished but you plan to finish it, please mark it as a draft.
|
||||
3. If you don't expect to work on it any time soon, closing it with a short comment may encourage someone else to pick up your work.
|
||||
4. To get things rolling again, rebase the PR against the target branch and address valid comments.
|
||||
5. If you need a review to move forward, ask in [the Discourse thread for PRs that need help](https://discourse.nixos.org/t/prs-in-distress/3604).
|
||||
6. If all you need is a merge, check the git history to find and [request reviews](https://docs.github.com/en/github/collaborating-with-issues-and-pull-requests/requesting-a-pull-request-review) from people who usually merge related contributions.
|
||||
|
||||
## Suggestions for issues
|
||||
|
||||
1. If it is resolved (either for you personally, or in general), please consider closing it.
|
||||
2. If this might still be an issue, but you are not interested in promoting its resolution, please consider closing it while encouraging others to take over and reopen an issue if they care enough.
|
||||
3. If you still have interest in resolving it, try to ping somebody who you believe might have an interest in the topic. Consider discussing the problem in [our Discourse Forum](https://discourse.nixos.org/).
|
||||
4. As with all open source projects, your best option is to submit a Pull Request that addresses this issue. We :heart: this attitude!
|
||||
|
||||
**Memorandum on closing issues**
|
||||
|
||||
Don't be afraid to close an issue that holds valuable information. Closed issues stay in the system for people to search, read, cross-reference, or even reopen--nothing is lost! Closing obsolete issues is an important way to help maintainers focus their time and effort.

# 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.
|
||||
|
||||
Issues labeled [good first issue](https://github.com/NixOS/nix/labels/good-first-issue) should be relatively easy to fix and are likely to get merged quickly.
|
||||
Pull requests addressing issues labeled [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) are especially welcomed by maintainers and will receive prioritised review.
|
||||
|
||||
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.
|
||||
* Link related issues in your pull request to inform interested parties and future contributors about your change.
|
||||
* 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).
|
||||
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.
|
||||
* [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.
|
||||
|
||||
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.
|
||||
|
||||
Following this checklist will make the process smoother for everyone:
|
||||
|
||||
- [ ] Fixes an [idea approved](https://github.com/NixOS/nix/labels/idea%20approved) issue
|
||||
- [ ] Tests, as appropriate:
|
||||
- Functional tests – [`tests/functional/**.sh`](./tests/functional)
|
||||
- Unit tests – [`src/*/tests`](./src/)
|
||||
- Integration tests – [`tests/nixos/*`](./tests/nixos)
|
||||
- [ ] User documentation in the [manual](..doc/manual/src)
|
||||
- [ ] API documentation in header files
|
||||
- [ ] Code and comments are self-explanatory
|
||||
- [ ] Commit message explains **why** the change was made
|
||||
- [ ] New feature or incompatible change: updated [release notes](./doc/manual/src/release-notes/rl-next.md)
|
||||
|
||||
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.

GNU LESSER GENERAL PUBLIC LICENSE
|
||||
Version 2.1, February 1999
|
||||
|
||||
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
|
||||
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
Everyone is permitted to copy and distribute verbatim copies
|
||||
of this license document, but changing it is not allowed.
|
||||
|
||||
[This is the first released version of the Lesser GPL. It also counts
|
||||
as the successor of the GNU Library Public License, version 2, hence
|
||||
the version number 2.1.]
|
||||
|
||||
Preamble
|
||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
Licenses are intended to guarantee your freedom to share and change
|
||||
free software--to make sure the software is free for all its users.
|
||||
|
||||
This license, the Lesser General Public License, applies to some
|
||||
specially designated software packages--typically libraries--of the
|
||||
Free Software Foundation and other authors who decide to use it. You
|
||||
can use it too, but we suggest you first think carefully about whether
|
||||
this license or the ordinary General Public License is the better
|
||||
strategy to use in any particular case, based on the explanations below.
|
||||
|
||||
When we speak of free software, we are referring to freedom of use,
|
||||
not price. Our General Public Licenses are designed to make sure that
|
||||
you have the freedom to distribute copies of free software (and charge
|
||||
for this service if you wish); that you receive source code or can get
|
||||
it if you want it; that you can change the software and use pieces of
|
||||
it in new free programs; and that you are informed that you can do
|
||||
these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
distributors to deny you these rights or to ask you to surrender these
|
||||
rights. These restrictions translate to certain responsibilities for
|
||||
you if you distribute copies of the library or if you modify it.
|
||||
|
||||
For example, if you distribute copies of the library, whether gratis
|
||||
or for a fee, you must give the recipients all the rights that we gave
|
||||
you. You must make sure that they, too, receive or can get the source
|
||||
code. If you link other code with the library, you must provide
|
||||
complete object files to the recipients, so that they can relink them
|
||||
with the library after making changes to the library and recompiling
|
||||
it. And you must show them these terms so they know their rights.
|
||||
|
||||
We protect your rights with a two-step method: (1) we copyright the
|
||||
library, and (2) we offer you this license, which gives you legal
|
||||
permission to copy, distribute and/or modify the library.
|
||||
|
||||
To protect each distributor, we want to make it very clear that
|
||||
there is no warranty for the free library. Also, if the library is
|
||||
modified by someone else and passed on, the recipients should know
|
||||
that what they have is not the original version, so that the original
|
||||
author's reputation will not be affected by problems that might be
|
||||
introduced by others.
|
||||
|
||||
Finally, software patents pose a constant threat to the existence of
|
||||
any free program. We wish to make sure that a company cannot
|
||||
effectively restrict the users of a free program by obtaining a
|
||||
restrictive license from a patent holder. Therefore, we insist that
|
||||
any patent license obtained for a version of the library must be
|
||||
consistent with the full freedom of use specified in this license.
|
||||
|
||||
Most GNU software, including some libraries, is covered by the
|
||||
ordinary GNU General Public License. This license, the GNU Lesser
|
||||
General Public License, applies to certain designated libraries, and
|
||||
is quite different from the ordinary General Public License. We use
|
||||
this license for certain libraries in order to permit linking those
|
||||
libraries into non-free programs.
|
||||
|
||||
When a program is linked with a library, whether statically or using
|
||||
a shared library, the combination of the two is legally speaking a
|
||||
combined work, a derivative of the original library. The ordinary
|
||||
General Public License therefore permits such linking only if the
|
||||
entire combination fits its criteria of freedom. The Lesser General
|
||||
Public License permits more lax criteria for linking other code with
|
||||
the library.
|
||||
|
||||
We call this license the "Lesser" General Public License because it
|
||||
does Less to protect the user's freedom than the ordinary General
|
||||
Public License. It also provides other free software developers Less
|
||||
of an advantage over competing non-free programs. These disadvantages
|
||||
are the reason we use the ordinary General Public License for many
|
||||
libraries. However, the Lesser license provides advantages in certain
|
||||
special circumstances.
|
||||
|
||||
For example, on rare occasions, there may be a special need to
|
||||
encourage the widest possible use of a certain library, so that it becomes
|
||||
a de-facto standard. To achieve this, non-free programs must be
|
||||
allowed to use the library. A more frequent case is that a free
|
||||
library does the same job as widely used non-free libraries. In this
|
||||
case, there is little to gain by limiting the free library to free
|
||||
software only, so we use the Lesser General Public License.
|
||||
|
||||
In other cases, permission to use a particular library in non-free
|
||||
programs enables a greater number of people to use a large body of
|
||||
free software. For example, permission to use the GNU C Library in
|
||||
non-free programs enables many more people to use the whole GNU
|
||||
operating system, as well as its variant, the GNU/Linux operating
|
||||
system.
|
||||
|
||||
Although the Lesser General Public License is Less protective of the
|
||||
users' freedom, it does ensure that the user of a program that is
|
||||
linked with the Library has the freedom and the wherewithal to run
|
||||
that program using a modified version of the Library.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow. Pay close attention to the difference between a
|
||||
"work based on the library" and a "work that uses the library". The
|
||||
former contains code derived from the library, whereas the latter must
|
||||
be combined with the library in order to run.
|
||||
|
||||
GNU LESSER GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License Agreement applies to any software library or other
|
||||
program which contains a notice placed by the copyright holder or
|
||||
other authorized party saying it may be distributed under the terms of
|
||||
this Lesser General Public License (also called "this License").
|
||||
Each licensee is addressed as "you".
|
||||
|
||||
A "library" means a collection of software functions and/or data
|
||||
prepared so as to be conveniently linked with application programs
|
||||
(which use some of those functions and data) to form executables.
|
||||
|
||||
The "Library", below, refers to any such software library or work
|
||||
which has been distributed under these terms. A "work based on the
|
||||
Library" means either the Library or any derivative work under
|
||||
copyright law: that is to say, a work containing the Library or a
|
||||
portion of it, either verbatim or with modifications and/or translated
|
||||
straightforwardly into another language. (Hereinafter, translation is
|
||||
included without limitation in the term "modification".)
|
||||
|
||||
"Source code" for a work means the preferred form of the work for
|
||||
making modifications to it. For a library, complete source code means
|
||||
all the source code for all modules it contains, plus any associated
|
||||
interface definition files, plus the scripts used to control compilation
|
||||
and installation of the library.
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running a program using the Library is not restricted, and output from
|
||||
such a program is covered only if its contents constitute a work based
|
||||
on the Library (independent of the use of the Library in a tool for
|
||||
writing it). Whether that is true depends on what the Library does
|
||||
and what the program that uses the Library does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Library's
|
||||
complete source code as you receive it, in any medium, provided that
|
||||
you conspicuously and appropriately publish on each copy an
|
||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
||||
all the notices that refer to this License and to the absence of any
|
||||
warranty; and distribute a copy of this License along with the
|
||||
Library.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy,
|
||||
and you may at your option offer warranty protection in exchange for a
|
||||
fee.
|
||||
|
||||
2. You may modify your copy or copies of the Library or any portion
|
||||
of it, thus forming a work based on the Library, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) The modified work must itself be a software library.
|
||||
|
||||
b) You must cause the files modified to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
c) You must cause the whole of the work to be licensed at no
|
||||
charge to all third parties under the terms of this License.
|
||||
|
||||
d) If a facility in the modified Library refers to a function or a
|
||||
table of data to be supplied by an application program that uses
|
||||
the facility, other than as an argument passed when the facility
|
||||
is invoked, then you must make a good faith effort to ensure that,
|
||||
in the event an application does not supply such function or
|
||||
table, the facility still operates, and performs whatever part of
|
||||
its purpose remains meaningful.
|
||||
|
||||
(For example, a function in a library to compute square roots has
|
||||
a purpose that is entirely well-defined independent of the
|
||||
application. Therefore, Subsection 2d requires that any
|
||||
application-supplied function or table used by this function must
|
||||
be optional: if the application does not supply it, the square
|
||||
root function must still compute square roots.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Library,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Library, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote
|
||||
it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Library.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Library
|
||||
with the Library (or with a work based on the Library) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||
License instead of this License to a given copy of the Library. To do
|
||||
this, you must alter all the notices that refer to this License, so
|
||||
that they refer to the ordinary GNU General Public License, version 2,
|
||||
instead of to this License. (If a newer version than version 2 of the
|
||||
ordinary GNU General Public License has appeared, then you can specify
|
||||
that version instead if you wish.) Do not make any other change in
|
||||
these notices.
|
||||
|
||||
Once this change is made in a given copy, it is irreversible for
|
||||
that copy, so the ordinary GNU General Public License applies to all
|
||||
subsequent copies and derivative works made from that copy.
|
||||
|
||||
This option is useful when you wish to copy part of the code of
|
||||
the Library into a program that is not a library.
|
||||
|
||||
4. You may copy and distribute the Library (or a portion or
|
||||
derivative of it, under Section 2) in object code or executable form
|
||||
under the terms of Sections 1 and 2 above provided that you accompany
|
||||
it with the complete corresponding machine-readable source code, which
|
||||
must be distributed under the terms of Sections 1 and 2 above on a
|
||||
medium customarily used for software interchange.
|
||||
|
||||
If distribution of object code is made by offering access to copy
|
||||
from a designated place, then offering equivalent access to copy the
|
||||
source code from the same place satisfies the requirement to
|
||||
distribute the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
5. A program that contains no derivative of any portion of the
|
||||
Library, but is designed to work with the Library by being compiled or
|
||||
linked with it, is called a "work that uses the Library". Such a
|
||||
work, in isolation, is not a derivative work of the Library, and
|
||||
therefore falls outside the scope of this License.
|
||||
|
||||
However, linking a "work that uses the Library" with the Library
|
||||
creates an executable that is a derivative of the Library (because it
|
||||
contains portions of the Library), rather than a "work that uses the
|
||||
library". The executable is therefore covered by this License.
|
||||
Section 6 states terms for distribution of such executables.
|
||||
|
||||
When a "work that uses the Library" uses material from a header file
|
||||
that is part of the Library, the object code for the work may be a
|
||||
derivative work of the Library even though the source code is not.
|
||||
Whether this is true is especially significant if the work can be
|
||||
linked without the Library, or if the work is itself a library. The
|
||||
threshold for this to be true is not precisely defined by law.
|
||||
|
||||
If such an object file uses only numerical parameters, data
|
||||
structure layouts and accessors, and small macros and small inline
|
||||
functions (ten lines or less in length), then the use of the object
|
||||
file is unrestricted, regardless of whether it is legally a derivative
|
||||
work. (Executables containing this object code plus portions of the
|
||||
Library will still fall under Section 6.)
|
||||
|
||||
Otherwise, if the work is a derivative of the Library, you may
|
||||
distribute the object code for the work under the terms of Section 6.
|
||||
Any executables containing that work also fall under Section 6,
|
||||
whether or not they are linked directly with the Library itself.
|
||||
|
||||
6. As an exception to the Sections above, you may also combine or
|
||||
link a "work that uses the Library" with the Library to produce a
|
||||
work containing portions of the Library, and distribute that work
|
||||
under terms of your choice, provided that the terms permit
|
||||
modification of the work for the customer's own use and reverse
|
||||
engineering for debugging such modifications.
|
||||
|
||||
You must give prominent notice with each copy of the work that the
|
||||
Library is used in it and that the Library and its use are covered by
|
||||
this License. You must supply a copy of this License. If the work
|
||||
during execution displays copyright notices, you must include the
|
||||
copyright notice for the Library among them, as well as a reference
|
||||
directing the user to the copy of this License. Also, you must do one
|
||||
of these things:
|
||||
|
||||
a) Accompany the work with the complete corresponding
|
||||
machine-readable source code for the Library including whatever
|
||||
changes were used in the work (which must be distributed under
|
||||
Sections 1 and 2 above); and, if the work is an executable linked
|
||||
with the Library, with the complete machine-readable "work that
|
||||
uses the Library", as object code and/or source code, so that the
|
||||
user can modify the Library and then relink to produce a modified
|
||||
executable containing the modified Library. (It is understood
|
||||
that the user who changes the contents of definitions files in the
|
||||
Library will not necessarily be able to recompile the application
|
||||
to use the modified definitions.)
|
||||
|
||||
b) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (1) uses at run time a
|
||||
copy of the library already present on the user's computer system,
|
||||
rather than copying library functions into the executable, and (2)
|
||||
will operate properly with a modified version of the library, if
|
||||
the user installs one, as long as the modified version is
|
||||
interface-compatible with the version that the work was made with.
|
||||
|
||||
c) Accompany the work with a written offer, valid for at
|
||||
least three years, to give the same user the materials
|
||||
specified in Subsection 6a, above, for a charge no more
|
||||
than the cost of performing this distribution.
|
||||
|
||||
d) If distribution of the work is made by offering access to copy
|
||||
from a designated place, offer equivalent access to copy the above
|
||||
specified materials from the same place.
|
||||
|
||||
e) Verify that the user has already received a copy of these
|
||||
materials or that you have already sent this user a copy.
|
||||
|
||||
For an executable, the required form of the "work that uses the
|
||||
Library" must include any data and utility programs needed for
|
||||
reproducing the executable from it. However, as a special exception,
|
||||
the materials to be distributed need not include anything that is
|
||||
normally distributed (in either source or binary form) with the major
|
||||
components (compiler, kernel, and so on) of the operating system on
|
||||
which the executable runs, unless that component itself accompanies
|
||||
the executable.
|
||||
|
||||
It may happen that this requirement contradicts the license
|
||||
restrictions of other proprietary libraries that do not normally
|
||||
accompany the operating system. Such a contradiction means you cannot
|
||||
use both them and the Library together in an executable that you
|
||||
distribute.
|
||||
|
||||
7. You may place library facilities that are a work based on the
|
||||
Library side-by-side in a single library together with other library
|
||||
facilities not covered by this License, and distribute such a combined
|
||||
library, provided that the separate distribution of the work based on
|
||||
the Library and of the other library facilities is otherwise
|
||||
permitted, and provided that you do these two things:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work
|
||||
based on the Library, uncombined with any other library
|
||||
facilities. This must be distributed under the terms of the
|
||||
Sections above.
|
||||
|
||||
b) Give prominent notice with the combined library of the fact
|
||||
that part of it is a work based on the Library, and explaining
|
||||
where to find the accompanying uncombined form of the same work.
|
||||
|
||||
8. You may not copy, modify, sublicense, link with, or distribute
|
||||
the Library except as expressly provided under this License. Any
|
||||
attempt otherwise to copy, modify, sublicense, link with, or
|
||||
distribute the Library is void, and will automatically terminate your
|
||||
rights under this License. However, parties who have received copies,
|
||||
or rights, from you under this License will not have their licenses
|
||||
terminated so long as such parties remain in full compliance.
|
||||
|
||||
9. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Library or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Library (or any work based on the
|
||||
Library), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Library or works based on it.
|
||||
|
||||
10. Each time you redistribute the Library (or any work based on the
|
||||
Library), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute, link with or modify the Library
|
||||
subject to these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties with
|
||||
this License.
|
||||
|
||||
11. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Library at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Library by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Library.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under any
|
||||
particular circumstance, the balance of the section is intended to apply,
|
||||
and the section as a whole is intended to apply in other circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
12. If the distribution and/or use of the Library is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Library under this License may add
|
||||
an explicit geographical distribution limitation excluding those countries,
|
||||
so that distribution is permitted only in or among countries not thus
|
||||
excluded. In such case, this License incorporates the limitation as if
|
||||
written in the body of this License.
|
||||
|
||||
13. The Free Software Foundation may publish revised and/or new
|
||||
versions of the Lesser General Public License from time to time.
|
||||
Such new versions will be similar in spirit to the present version,
|
||||
but may differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Library
|
||||
specifies a version number of this License which applies to it and
|
||||
"any later version", you have the option of following the terms and
|
||||
conditions either of that version or of any later version published by
|
||||
the Free Software Foundation. If the Library does not specify a
|
||||
license version number, you may choose any version ever published by
|
||||
the Free Software Foundation.
|
||||
|
||||
14. If you wish to incorporate parts of the Library into other free
|
||||
programs whose distribution conditions are incompatible with these,
|
||||
write to the author to ask for permission. For software which is
|
||||
copyrighted by the Free Software Foundation, write to the Free
|
||||
Software Foundation; we sometimes make exceptions for this. Our
|
||||
decision will be guided by the two goals of preserving the free status
|
||||
of all derivatives of our free software and of promoting the sharing
|
||||
and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||
THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
|
||||
|
||||
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
|
||||
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
|
||||
AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
|
||||
FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
|
||||
CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
|
||||
LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
|
||||
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
|
||||
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
|
||||
SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
|
||||
DAMAGES.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
How to Apply These Terms to Your New Libraries
|
||||
|
||||
If you develop a new library, and you want it to be of the greatest
|
||||
possible use to the public, we recommend making it free software that
|
||||
everyone can redistribute and change. You can do so by permitting
|
||||
redistribution under these terms (or, alternatively, under the terms of the
|
||||
ordinary General Public License).
|
||||
|
||||
To apply these terms, attach the following notices to the library. It is
|
||||
safest to attach them to the start of each source file to most effectively
|
||||
convey the exclusion of warranty; and each file should have at least the
|
||||
"copyright" line and a pointer to where the full notice is found.
|
||||
|
||||
<one line to give the library's name and a brief idea of what it does.>
|
||||
Copyright (C) <year> <name of author>
|
||||
|
||||
This library is free software; you can redistribute it and/or
|
||||
modify it under the terms of the GNU Lesser General Public
|
||||
License as published by the Free Software Foundation; either
|
||||
version 2.1 of the License, or (at your option) any later version.
|
||||
|
||||
This library is distributed in the hope that it will be useful,
|
||||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU
|
||||
Lesser General Public License for more details.
|
||||
|
||||
You should have received a copy of the GNU Lesser General Public
|
||||
License along with this library; if not, write to the Free Software
|
||||
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
|
||||
|
||||
Also add information on how to contact you by electronic and paper mail.
|
||||
|
||||
You should also get your employer (if you work as a programmer) or your
|
||||
school, if any, to sign a "copyright disclaimer" for the library, if
|
||||
necessary. Here is a sample; alter the names:
|
||||
|
||||
Yoyodyne, Inc., hereby disclaims all copyright interest in the
|
||||
library `Frob' (a library for tweaking knobs) written by James Random Hacker.

Nix is a powerful package manager for Linux and other Unix systems that makes package
|
||||
management reliable and reproducible. Please refer to the [Nix manual](https://nixos.org/nix/manual)
|
||||
for more details.
|
||||
|
||||
## Installation
|
||||
|
||||
On Linux and macOS the easiest way to install Nix is to run the following shell command
|
||||
(as a user other than root):
|
||||
|
||||
```console
|
||||
$ curl -L https://nixos.org/nix/install | sh
|
||||
```
|
||||
|
||||
Information on additional installation methods is available on the [Nix download page](https://nixos.org/download.html).
|
||||
|
||||
## Building And Developing
|
||||
|
||||
See our [Hacking guide](https://nixos.org/manual/nix/unstable/contributing/hacking.html) in our manual for instruction on how to
|
||||
to set up a development environment and build Nix from source.

// therefore we avoid function calls, copying data, and unnecessary loops.
|
||||
// IMPORTANT: we use stateful array operations and their order matters!
|
||||
//
|
||||
// matching URLs is more involved than it should be:
|
||||
//
|
||||
// 1. `document.location.pathname` can have an arbitrary prefix.
|
||||
//
|
||||
// 2. `path_to_root` is set by mdBook. it consists only of `../`s and
|
||||
// determines the depth of `<path>` relative to the prefix:
|
||||
//
|
||||
// `document.location.pathname`
|
||||
// |------------------------------|
|
||||
// /<prefix>/<path>/[<file>[.html]][#<anchor>]
|
||||
// |----|
|
||||
// `path_to_root` has same number of path segments
|
||||
//
|
||||
// source: https://phaiax.github.io/mdBook/format/theme/index-hbs.html#data
|
||||
//
|
||||
// 3. the following paths are equivalent:
|
||||
//
|
||||
// /foo/bar/
|
||||
// /foo/bar/index.html
|
||||
// /foo/bar/index
|
||||
//
|
||||
// 4. the following paths are also equivalent:
|
||||
//
|
||||
// /foo/bar/baz
|
||||
// /foo/bar/baz.html
|
||||
//
|

|

|
||||
|
||||
// use `path_to_root` to discern prefix from path.
|
||||
const depth = path_to_root.split('/').length;
|
||||
|
||||
// remove segments containing prefix. the following works because
|
||||
// 1. the original `document.location.pathname` is absolute,
|
||||
// hence first element of `segments` is always empty.
|
||||
// 2. last element of splitting `path_to_root` is also always empty.
|
||||
// 3. last element of `segments` is the file name.
|
||||
//
|
||||
// visual example:
|
||||
//
|
||||
// '/foo/bar/baz.html'.split('/') -> [ '', 'foo', 'bar', 'baz.html' ]
|
||||
// '../'.split('/') -> [ '..', '' ]
|
||||
//
|
||||
// the following operations will then result in
|
||||
//
|
||||
// path = 'bar/baz.html'

//

const path = segments.join('/');
|
||||
|
||||
// anchor starts with the hash character (`#`),
|
||||
// but our redirect declarations don't, so we strip it.
|

// example:
|
||||
// document.location.hash -> '#foo'
|

// document.location.hash.substring(1) -> 'foo'

# Tuning Cores and Jobs
|
||||
|
||||
Nix has two relevant settings with regards to how your CPU cores will
|
||||
be utilized: `cores` and `max-jobs`. This chapter will talk about what
|
||||
they are, how they interact, and their configuration trade-offs.
|
||||
|
||||
- `max-jobs`\
|
||||
Dictates how many separate derivations will be built at the same
|
||||
time. If you set this to zero, the local machine will do no
|
||||
builds. Nix will still substitute from binary caches, and build
|
||||
remotely if remote builders are configured.
|
||||
|
||||
- `cores`\
|
||||
Suggests how many cores each derivation should use. Similar to
|
||||
`make -j`.
|
||||
|
||||
The `cores` setting determines the value of
|
||||
`NIX_BUILD_CORES`. `NIX_BUILD_CORES` is equal to `cores`, unless
|
||||
`cores` equals `0`, in which case `NIX_BUILD_CORES` will be the total
|
||||
number of cores in the system.
|
||||
|
||||
The maximum number of consumed cores is a simple multiplication,
|
||||
`max-jobs` \* `NIX_BUILD_CORES`.
|
||||
|
||||
The balance on how to set these two independent variables depends upon
|
||||
each builder's workload and hardware. Here are a few example scenarios
|
||||
on a machine with 24 cores:
|
||||
|
||||
| `max-jobs` | `cores` | `NIX_BUILD_CORES` | Maximum Processes | Result |
|
||||
| --------------------- | ------------------ | ----------------- | ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
|
||||
| 1 | 24 | 24 | 24 | One derivation will be built at a time, each one can use 24 cores. Undersold if a job can’t use 24 cores. |
|
||||
| 4 | 6 | 6 | 24 | Four derivations will be built at once, each given access to six cores. |
|
||||
| 12 | 6 | 6 | 72 | 12 derivations will be built at once, each given access to six cores. This configuration is over-sold. If all 12 derivations being built simultaneously try to use all six cores, the machine's performance will be degraded due to extensive context switching between the 12 builds. |
|
||||
| 24 | 1 | 1 | 24 | 24 derivations can build at the same time, each using a single core. Never oversold, but derivations which require many cores will be very slow to compile. |
|
||||
| 24 | 0 | 24 | 576 | 24 derivations can build at the same time, each using all the available cores of the machine. Very likely to be oversold, and very likely to suffer context switches. |
|
||||
|
||||
It is up to the derivations' build script to respect host's requested
|
||||
cores-per-build by following the value of the `NIX_BUILD_CORES`
|
||||
environment variable.

# Verifying Build Reproducibility
|
||||
|
||||
You can use Nix's `diff-hook` setting to compare build results. Note
|
||||
that this hook is only executed if the results differ; it is not used
|
||||
for determining if the results are the same.
|
||||
|
||||
For purposes of demonstration, we'll use the following Nix file,
|
||||
`deterministic.nix` for testing:
|
||||
|
||||
```nix
|
||||
let
|
||||
inherit (import <nixpkgs> {}) runCommand;
|
||||
in {
|
||||
stable = runCommand "stable" {} ''
|
||||
touch $out
|
||||
'';
|
||||
|
||||
unstable = runCommand "unstable" {} ''
|
||||
echo $RANDOM > $out
|
||||
'';
|
||||
}
|
||||
```
|
||||
|
||||
Additionally, `nix.conf` contains:
|
||||
|
||||
diff-hook = /etc/nix/my-diff-hook
|
||||
run-diff-hook = true
|
||||
|
||||
where `/etc/nix/my-diff-hook` is an executable file containing:
|
||||
|
||||
```bash
|
||||
#!/bin/sh
|
||||
exec >&2
|
||||
echo "For derivation $3:"
|
||||
/run/current-system/sw/bin/diff -r "$1" "$2"
|
||||
```
|
||||
|
||||
The diff hook is executed by the same user and group who ran the build.
|
||||
However, the diff hook does not have write access to the store path just
|
||||
built.
|
||||
|
||||
# Spot-Checking Build Determinism
|
||||
|
||||
Verify a path which already exists in the Nix store by passing `--check`
|
||||
to the build command.
|
||||
|
||||
If the build passes and is deterministic, Nix will exit with a status
|
||||
code of 0:
|
||||
|
||||
```console
|
||||
$ nix-build ./deterministic.nix --attr stable
|
||||
this derivation will be built:
|
||||
/nix/store/z98fasz2jqy9gs0xbvdj939p27jwda38-stable.drv
|
||||

||||
/nix/store/yyxlzw3vqaas7wfp04g0b1xg51f2czgq-stable

|
||||
/nix/store/yyxlzw3vqaas7wfp04g0b1xg51f2czgq-stable
|
||||
```
|
||||
|
||||
If the build is not deterministic, Nix will exit with a status code of
|
||||
1:
|
||||
|
||||
```console
|
||||
$ nix-build ./deterministic.nix --attr unstable
|
||||
this derivation will be built:
|
||||
/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv

||||

||||

||||

|
||||
error: derivation '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv' may

||||
not be deterministic: output '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable' differs
|
||||
```
|
||||
|
||||
In the Nix daemon's log, we will now see:
|
||||
|
||||
```
|
||||
For derivation /nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv:

||||

|
||||
---
|
||||
> 30204
|
||||
```
|
||||
|
||||
Using `--check` with `--keep-failed` will cause Nix to keep the second
|
||||
build's output in a special, `.check` path:
|
||||
|
||||
```console
|
||||
$ nix-build ./deterministic.nix --attr unstable --check --keep-failed
|
||||
checking outputs of '/nix/store/cgl13lbj1w368r5z8gywipl1ifli7dhk-unstable.drv'...
|

note: keeping build directory '/tmp/nix-build-unstable.drv-0'

from '/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check'
|
||||
```
|
||||
|
||||
In particular, notice the
|
||||
`/nix/store/krpqk0l9ib0ibi1d2w52z293zw455cap-unstable.check` output. Nix
|
||||
has copied the build results to that directory where you can examine it.

|
||||
|
||||
`--check` is only usable if the derivation has been built on the system
|
||||
already. If the derivation has not been built Nix will fail with the
|
||||
error:
|
||||
|
||||
error: some outputs of '/nix/store/hzi1h60z2qf0nb85iwnpvrai3j2w7rr6-unstable.drv'
|
||||
are not valid, so checking is not possible
|
||||
|
||||
Run the build without `--check`, and then try with `--check` again.

# Remote Builds
|
||||
|
||||
Nix supports remote builds, where a local Nix installation can forward
|
||||
Nix builds to other machines. This allows multiple builds to be
|
||||
performed in parallel and allows Nix to perform multi-platform builds in
|
||||
a semi-transparent way. For instance, if you perform a build for a
|
||||
`x86_64-darwin` on an `i686-linux` machine, Nix can automatically
|
||||
forward the build to a `x86_64-darwin` machine, if available.
|
||||
|
||||
To forward a build to a remote machine, it’s required that the remote
|
||||
machine is accessible via SSH and that it has Nix installed. You can
|
||||
test whether connecting to the remote Nix instance works, e.g.
|
||||
|
||||
```console
|
||||
$ nix store ping --store ssh://mac
|
||||
```
|
||||
|
||||
will try to connect to the machine named `mac`. It is possible to
|
||||
specify an SSH identity file as part of the remote store URI, e.g.
|
||||
|
||||
```console
|
||||
$ nix store ping --store ssh://mac?ssh-key=/home/alice/my-key
|
||||
```
|
||||
|
||||
Since builds should be non-interactive, the key should not have a
|
||||
passphrase. Alternatively, you can load identities ahead of time into
|
||||
`ssh-agent` or `gpg-agent`.
|
||||
|
||||
If you get the error
|
||||
|
||||
```console
|
||||
bash: nix-store: command not found
|
||||
error: cannot connect to 'mac'
|
||||
```
|
||||
|
||||
then you need to ensure that the `PATH` of non-interactive login shells
|
||||
contains Nix.
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> If you are building via the Nix daemon, it is the Nix daemon user account (that is, `root`) that should have SSH access to a user (not necessarily `root`) on the remote machine.
|
||||
>
|
||||
> If you can’t or don’t want to configure `root` to be able to access the remote machine, you can use a private Nix store instead by passing e.g. `--store ~/my-nix` when running a Nix command from the local machine.
|
||||
|
||||
The list of remote machines can be specified on the command line or in
|
||||
the Nix configuration file. The former is convenient for testing. For
|
||||
example, the following command allows you to build a derivation for
|
||||
`x86_64-darwin` on a Linux machine:
|
||||
|
||||
```console
|
||||
$ uname
|
||||
Linux
|
||||
|
||||
$ nix build --impure \
|
||||
--expr '(with import <nixpkgs> { system = "x86_64-darwin"; }; runCommand "foo" {} "uname > $out")' \
|
||||
--builders 'ssh://mac x86_64-darwin'
|
||||
[1/0/1 built, 0.0 MiB DL] building foo on ssh://mac
|
||||
|
||||
$ cat ./result
|
||||
Darwin
|
||||
```
|
||||
|
||||
It is possible to specify multiple builders separated by a semicolon or
|
||||
a newline, e.g.
|
||||
|
||||
```console
|
||||
--builders 'ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd'
|
||||
```
|
||||
|
||||
Each machine specification consists of the following elements, separated
|
||||
by spaces. Only the first element is required. To leave a field at its
|
||||
default, set it to `-`.
|
||||
|
||||
1. The URI of the remote store in the format
|
||||
`ssh://[username@]hostname`, e.g. `ssh://nix@mac` or `ssh://mac`.
|
||||
For backward compatibility, `ssh://` may be omitted. The hostname
|
||||
may be an alias defined in your `~/.ssh/config`.
|
||||
|
||||
2. A comma-separated list of Nix platform type identifiers, such as
|
||||
`x86_64-darwin`. It is possible for a machine to support multiple
|
||||
platform types, e.g., `i686-linux,x86_64-linux`. If omitted, this
|
||||
defaults to the local platform type.
|
||||
|
||||
3. The SSH identity file to be used to log in to the remote machine. If
|
||||
omitted, SSH will use its regular identities.
|
||||
|
||||
4. The maximum number of builds that Nix will execute in parallel on
|
||||
the machine. Typically this should be equal to the number of CPU
|
||||
cores. For instance, the machine `itchy` in the example will execute
|
||||
up to 8 builds in parallel.
|
||||
|
||||
5. The “speed factor”, indicating the relative speed of the machine. If
|
||||
there are multiple machines of the right type, Nix will prefer the
|
||||
fastest, taking load into account.
|
||||
|
||||
6. A comma-separated list of *supported features*. If a derivation has
|
||||
the `requiredSystemFeatures` attribute, then Nix will only perform
|
||||
the derivation on a machine that has the specified features. For
|
||||
instance, the attribute
|
||||
|
||||
```nix
|
||||
requiredSystemFeatures = [ "kvm" ];
|
||||
```
|
||||
|
||||
will cause the build to be performed on a machine that has the `kvm`
|
||||
feature.
|
||||
|
||||
7. A comma-separated list of *mandatory features*. A machine will only
|
||||
be used to build a derivation if all of the machine’s mandatory
|
||||
features appear in the derivation’s `requiredSystemFeatures`
|
||||
attribute.
|
||||
|
||||
8. The (base64-encoded) public host key of the remote machine. If omitted, SSH
|
||||
will use its regular known-hosts file. Specifically, the field is calculated
|
||||
via `base64 -w0 /etc/ssh/ssh_host_ed25519_key.pub`.
|
||||
|
||||
For example, the machine specification
|
||||
|
||||
nix@scratchy.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 8 1 kvm
|
||||
nix@itchy.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 8 2
|
||||
nix@poochie.labs.cs.uu.nl i686-linux /home/nix/.ssh/id_scratchy_auto 1 2 kvm benchmark
|
||||
|
||||
specifies several machines that can perform `i686-linux` builds.
|
||||
However, `poochie` will only do builds that have the attribute
|
||||
|
||||
```nix
|
||||
requiredSystemFeatures = [ "benchmark" ];
|
||||
```
|
||||
|
||||
or
|
||||
|
||||
```nix
|
||||
requiredSystemFeatures = [ "benchmark" "kvm" ];
|
||||
```
|
||||
|
||||
`itchy` cannot do builds that require `kvm`, but `scratchy` does support
|
||||
such builds. For regular builds, `itchy` will be preferred over
|
||||
`scratchy` because it has a higher speed factor.
|
||||
|
||||
Remote builders can also be configured in `nix.conf`, e.g.
|
||||
|
||||
builders = ssh://mac x86_64-darwin ; ssh://beastie x86_64-freebsd
|
||||
|
||||
Finally, remote builders can be configured in a separate configuration
|
||||
file included in `builders` via the syntax `@file`. For example,
|
||||
|
||||
builders = @/etc/nix/machines
|
||||
|
||||
causes the list of machines in `/etc/nix/machines` to be included. (This
|
||||
is the default.)
|
||||
|
||||
If you want the builders to use caches, you likely want to set the
|
||||
option `builders-use-substitutes` in your local `nix.conf`.
|
||||
|
||||
To build only on remote builders and disable building on the local
|
||||
machine, you can use the option `--max-jobs 0`.

# Using the `post-build-hook`
|
||||
|
||||
# Implementation Caveats
|
||||
|
||||
Here we use the post-build hook to upload to a binary cache. This is a
|
||||
simple and working example, but it is not suitable for all use cases.
|
||||
|
||||
The post build hook program runs after each executed build, and blocks
|
||||
the build loop. The build loop exits if the hook program fails.
|
||||
|
||||
Concretely, this implementation will make Nix slow or unusable when the
|
||||
internet is slow or unreliable.
|
||||
|
||||
A more advanced implementation might pass the store paths to a
|
||||
user-supplied daemon or queue for processing the store paths outside of
|
||||
the build loop.
|
||||
|
||||
# Prerequisites
|
||||
|
||||
This tutorial assumes you have [configured an S3-compatible binary
|
||||
cache](../package-management/s3-substituter.md), and that the `root`
|
||||
user's default AWS profile can upload to the bucket.
|
||||
|
||||
# Set up a Signing Key
|
||||
|
||||
Use `nix-store --generate-binary-cache-key` to create our public and
|
||||
private signing keys. We will sign paths with the private key, and
|
||||
distribute the public key for verifying the authenticity of the paths.
|
||||
|
||||
```console
|
||||
# nix-store --generate-binary-cache-key example-nix-cache-1 /etc/nix/key.private /etc/nix/key.public
|
||||
# cat /etc/nix/key.public
|
||||
example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
|
||||
```
|
||||
|
||||
Then update [`nix.conf`](../command-ref/conf-file.md) on any machine that will access the cache.
|
||||
Add the cache URL to [`substituters`](../command-ref/conf-file.md#conf-substituters) and the public key to [`trusted-public-keys`](../command-ref/conf-file.md#conf-trusted-public-keys):
|
||||
|
||||
substituters = https://cache.nixos.org/ s3://example-nix-cache
|
||||
trusted-public-keys = cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY= example-nix-cache-1:1/cKDz3QCCOmwcztD2eV6Coggp6rqc9DGjWv7C0G+rM=
|
||||
|
||||
Machines that build for the cache must sign derivations using the private key.
|
||||
On those machines, add the path to the key file to the [`secret-key-files`](../command-ref/conf-file.md#conf-secret-key-files) field in their [`nix.conf`](../command-ref/conf-file.md):
|
||||
|
||||
secret-key-files = /etc/nix/key.private
|
||||
|
||||
We will restart the Nix daemon in a later step.
|
||||
|
||||
# Implementing the build hook
|
||||
|
||||
Write the following script to `/etc/nix/upload-to-cache.sh`:
|
||||
|
||||
```bash
|
||||
#!/bin/sh
|
||||
|
||||
set -eu
|
||||
set -f # disable globbing
|
||||
export IFS=' '
|
||||
|
||||
echo "Uploading paths" $OUT_PATHS
|
||||
exec nix copy --to "s3://example-nix-cache" $OUT_PATHS
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The `$OUT_PATHS` variable is a space-separated list of Nix store
|
||||
> paths. In this case, we expect and want the shell to perform word
|
||||
> splitting to make each output path its own argument to `nix
|
||||
> store sign`. Nix guarantees the paths will not contain any spaces,
|
||||
> however a store path might contain glob characters. The `set -f`
|
||||
> disables globbing in the shell.
|
||||
|
||||
Then make sure the hook program is executable by the `root` user:
|
||||
|
||||
```console
|
||||
# chmod +x /etc/nix/upload-to-cache.sh
|
||||
```
|
||||
|
||||
# Updating Nix Configuration
|
||||
|
||||
Edit `/etc/nix/nix.conf` to run our hook, by adding the following
|
||||
configuration snippet at the end:
|
||||
|
||||
post-build-hook = /etc/nix/upload-to-cache.sh
|
||||
|
||||
Then, restart the `nix-daemon`.
|
||||
|
||||
# Testing
|
||||
|
||||
Build any derivation, for example:
|
||||
|
||||
```console
|
||||

# Architecture
|
||||
|
||||
This chapter describes how Nix works.
|
||||
It should help users understand why Nix behaves as it does, and it should help developers understand how to modify Nix and how to write similar tools.
|
||||
|
||||
## Overview
|
||||
|
||||
Nix consists of [hierarchical layers].
|
||||
|
||||
[hierarchical layers]: https://en.wikipedia.org/wiki/Multitier_architecture#Layers
|
||||
|
||||
The following [concept map] shows its main components (rectangles), the objects they operate on (rounded rectangles), and their interactions (connecting phrases):

```
|
||||
|
||||
At the top is the [command line interface](../command-ref/command-ref.md) that drives the underlying layers.
|
||||
|
||||
The [Nix language](../language/index.md) evaluator transforms Nix expressions into self-contained *build plans*, which are used to derive *build results* from referenced *build inputs*.
|
||||
|
||||
The command line interface and Nix expressions are what users deal with most.
|
||||
|
||||
> **Note**
|
||||
> The Nix language itself does not have a notion of *packages* or *configurations*.
|
||||
> As far as we are concerned here, the inputs and results of a build plan are just data.
|
||||
|
||||
Underlying the command line interface and the Nix language evaluator is the [Nix store](../glossary.md#gloss-store), a mechanism to keep track of build plans, data, and references between them.
|
||||
It can also execute build plans to produce new data, which are made available to the operating system as files.
|
||||
|
||||
A build plan itself is a series of *build tasks*, together with their build inputs.
|
||||
|
||||
> **Important**
|
||||
> A build task in Nix is called [derivation](../glossary.md#gloss-derivation).
|
||||
|
||||
Each build task has a special build input executed as *build instructions* in order to perform the build.
|
||||
The result of a build task can be input to another build task.
|
||||
|
||||
The following [data flow diagram] shows a build plan for illustration.
|
||||
Build inputs used as instructions to a build task are marked accordingly:

# File System Object
|
||||
|
||||
Nix uses a simplified model of the file system, which consists of file system objects.
|
||||
Every file system object is one of the following:
|
||||
|
||||
- File
|
||||
|
||||
- A possibly empty sequence of bytes for contents
|
||||
- A single boolean representing the [executable](https://en.m.wikipedia.org/wiki/File-system_permissions#Permissions) permission
|
||||
|
||||
- Directory
|
||||
|
||||
Mapping of names to child file system objects
|
||||
|
||||
- [Symbolic link](https://en.m.wikipedia.org/wiki/Symbolic_link)
|
||||
|
||||
An arbitrary string.
|
||||
Nix does not assign any semantics to symbolic links.
|
||||
|
||||
File system objects and their children form a tree.
|
||||
A bare file or symlink can be a root file system object.
|
||||
|
||||
Nix does not encode any other file system notions such as [hard links](https://en.m.wikipedia.org/wiki/Hard_link), [permissions](https://en.m.wikipedia.org/wiki/File-system_permissions), timestamps, or other metadata.
|
||||
|
||||
## Examples of file system objects
|
||||
|
||||
A plain file:
|
||||
|
||||
```
|
||||
50 B, executable: false
|
||||

An executable file:
|
||||
|
||||
```
|
||||
122 KB, executable: true
|
||||
```
|
||||
|
||||
A symlink:
|
||||
|
||||
```
|
||||
-> /usr/bin/sh
|

```
|

A directory with contents:

# Name
|
||||
|
||||
`nix.conf` - Nix configuration file
|
||||
|
||||
# Description
|
||||
|
||||
Nix supports a variety of configuration settings, which are read from configuration files or taken as command line flags.
|
||||
|
||||
## Configuration file
|
||||
|
||||
By default Nix reads settings from the following places, in that order:
|
||||
|
||||
1. The system-wide configuration file `sysconfdir/nix/nix.conf` (i.e. `/etc/nix/nix.conf` on most systems), or `$NIX_CONF_DIR/nix.conf` if [`NIX_CONF_DIR`](./env-common.md#env-NIX_CONF_DIR) is set.
|
||||
|
||||
Values loaded in this file are not forwarded to the Nix daemon.
|
||||
The client assumes that the daemon has already loaded them.
|
||||
|
||||
1. If [`NIX_USER_CONF_FILES`](./env-common.md#env-NIX_USER_CONF_FILES) is set, then each path separated by `:` will be loaded in reverse order.
|
||||
|
||||
Otherwise it will look for `nix/nix.conf` files in `XDG_CONFIG_DIRS` and [`XDG_CONFIG_HOME`](./env-common.md#env-XDG_CONFIG_HOME).
|
||||
If unset, `XDG_CONFIG_DIRS` defaults to `/etc/xdg`, and `XDG_CONFIG_HOME` defaults to `$HOME/.config` as per [XDG Base Directory Specification](https://specifications.freedesktop.org/basedir-spec/basedir-spec-latest.html).
|
||||
|
||||
1. If [`NIX_CONFIG`](./env-common.md#env-NIX_CONFIG) is set, its contents are treated as the contents of a configuration file.
|
||||
|
||||
### File format
|
||||
|
||||
Configuration files consist of `name = value` pairs, one per line.
|
||||
Comments start with a `#` character.
|
||||
|
||||
Example:
|
||||
|
||||
```
|
||||
keep-outputs = true # Nice for developers
|
||||
keep-derivations = true # Idem
|
||||
```
|
||||
|
||||
Other files can be included with a line like `include <path>`, where `<path>` is interpreted relative to the current configuration file.
|
||||
A missing file is an error unless `!include` is used instead.
|
||||
|
||||
A configuration setting usually overrides any previous value.
|
||||
However, for settings that take a list of items, you can prefix the name of the setting by `extra-` to *append* to the previous value.
|
||||
|
||||
For instance,
|
||||
|
||||
```
|
||||
substituters = a b
|
||||
extra-substituters = c d
|
||||
```
|
||||
|
||||
defines the `substituters` setting to be `a b c d`.
|
||||
|
||||
Unknown option names are not an error, and are simply ignored with a warning.
|
||||
|
||||
## Command line flags
|
||||
|
||||
Configuration options can be set on the command line, overriding the values set in the [configuration file](#configuration-file):
|
||||
|
||||
- Every configuration setting has corresponding command line flag (e.g. `--max-jobs 16`).
|
||||
Boolean settings do not need an argument, and can be explicitly disabled with the `no-` prefix (e.g. `--keep-failed` and `--no-keep-failed`).
|
||||
|
||||
Unknown option names are invalid flags (unless there is already a flag with that name), and are rejected with an error.
|
||||
|
||||
- The flag `--option <name> <value>` is interpreted exactly like a `<name> = <value>` in a setting file.
|
||||
|
||||
Unknown option names are ignored with a warning.
|
||||
|
||||
The `extra-` prefix is supported for settings that take a list of items (e.g. `--extra-trusted users alice` or `--option extra-trusted-users alice`).

# Common Environment Variables
|
||||
|
||||
Most Nix commands interpret the following environment variables:
|
||||
|
||||
- <span id="env-IN_NIX_SHELL">[`IN_NIX_SHELL`](#env-IN_NIX_SHELL)</span>\
|
||||
Indicator that tells if the current environment was set up by
|
||||
`nix-shell`. It can have the values `pure` or `impure`.
|
||||
|
||||
- <span id="env-NIX_PATH">[`NIX_PATH`](#env-NIX_PATH)</span>\
|
||||
A colon-separated list of directories used to look up the location of Nix
|
||||
expressions using [paths](@docroot@/language/values.md#type-path)
|
||||
enclosed in angle brackets (i.e., `<path>`),
|
||||
e.g. `/home/eelco/Dev:/etc/nixos`. It can be extended using the
|
||||
[`-I` option](@docroot@/command-ref/opt-common.md#opt-I).
|
||||
|
||||
If `NIX_PATH` is not set at all, Nix will fall back to the following list in [impure](@docroot@/command-ref/conf-file.md#conf-pure-eval) and [unrestricted](@docroot@/command-ref/conf-file.md#conf-restrict-eval) evaluation mode:
|
||||
|
||||
1. `$HOME/.nix-defexpr/channels`
|
||||
2. `nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixpkgs`
|
||||
3. `/nix/var/nix/profiles/per-user/root/channels`
|
||||
|
||||
If `NIX_PATH` is set to an empty string, resolving search paths will always fail.
|
||||
For example, attempting to use `<nixpkgs>` will produce:
|
||||
|
||||
error: file 'nixpkgs' was not found in the Nix search path
|
||||
|
||||
- <span id="env-NIX_IGNORE_SYMLINK_STORE">[`NIX_IGNORE_SYMLINK_STORE`](#env-NIX_IGNORE_SYMLINK_STORE)</span>\
|
||||
Normally, the Nix store directory (typically `/nix/store`) is not
|
||||
allowed to contain any symlink components. This is to prevent
|
||||
“impure” builds. Builders sometimes “canonicalise” paths by
|
||||
resolving all symlink components. Thus, builds on different machines
|
||||
(with `/nix/store` resolving to different locations) could yield
|
||||
different results. This is generally not a problem, except when
|
||||
builds are deployed to machines where `/nix/store` resolves
|
||||
differently. If you are sure that you’re not going to do that, you
|
||||
can set `NIX_IGNORE_SYMLINK_STORE` to `1`.
|
||||
|
||||
Note that if you’re symlinking the Nix store so that you can put it
|
||||
on another file system than the root file system, on Linux you’re
|
||||
better off using `bind` mount points, e.g.,
|
||||
|
||||
```console
|
||||
$ mkdir /nix
|
||||
$ mount -o bind /mnt/otherdisk/nix /nix
|
||||
```
|
||||
|
||||
Consult the mount 8 manual page for details.
|
||||
|
||||
- <span id="env-NIX_STORE_DIR">[`NIX_STORE_DIR`](#env-NIX_STORE_DIR)</span>\
|
||||
Overrides the location of the Nix store (default `prefix/store`).
|
||||
|
||||
- <span id="env-NIX_DATA_DIR">[`NIX_DATA_DIR`](#env-NIX_DATA_DIR)</span>\
|
||||
Overrides the location of the Nix static data directory (default
|
||||
`prefix/share`).
|
||||
|
||||
- <span id="env-NIX_LOG_DIR">[`NIX_LOG_DIR`](#env-NIX_LOG_DIR)</span>\
|
||||
Overrides the location of the Nix log directory (default
|
||||
`prefix/var/log/nix`).
|
||||
|
||||
- <span id="env-NIX_STATE_DIR">[`NIX_STATE_DIR`](#env-NIX_STATE_DIR)</span>\
|
||||
Overrides the location of the Nix state directory (default
|
||||
`prefix/var/nix`).
|
||||
|
||||
- <span id="env-NIX_CONF_DIR">[`NIX_CONF_DIR`](#env-NIX_CONF_DIR)</span>\
|
||||
Overrides the location of the system Nix configuration directory
|
||||
(default `prefix/etc/nix`).
|
||||
|
||||
- <span id="env-NIX_CONFIG">[`NIX_CONFIG`](#env-NIX_CONFIG)</span>\
|
||||
Applies settings from Nix configuration from the environment.
|
||||
The content is treated as if it was read from a Nix configuration file.
|
||||
Settings are separated by the newline character.
|
||||
|
||||
- <span id="env-NIX_USER_CONF_FILES">[`NIX_USER_CONF_FILES`](#env-NIX_USER_CONF_FILES)</span>\
|
||||
Overrides the location of the Nix user configuration files to load from.
|
||||
|
||||
The default are the locations according to the [XDG Base Directory Specification].
|
||||
See the [XDG Base Directories](#xdg-base-directories) sub-section for details.
|
||||
|
||||
The variable is treated as a list separated by the `:` token.
|
||||
|
||||
- <span id="env-TMPDIR">[`TMPDIR`](#env-TMPDIR)</span>\
|
||||
Use the specified directory to store temporary files. In particular,
|
||||
this includes temporary build directories; these can take up
|
||||
substantial amounts of disk space. The default is `/tmp`.
|
||||
|
||||
- <span id="env-NIX_REMOTE">[`NIX_REMOTE`](#env-NIX_REMOTE)</span>\
|
||||
This variable should be set to `daemon` if you want to use the Nix
|
||||
daemon to execute Nix operations. This is necessary in [multi-user
|
||||
Nix installations](@docroot@/installation/multi-user.md). If the Nix
|
||||
daemon's Unix socket is at some non-standard path, this variable
|
||||
should be set to `unix://path/to/socket`. Otherwise, it should be
|
||||
left unset.
|
||||
|
||||
- <span id="env-NIX_SHOW_STATS">[`NIX_SHOW_STATS`](#env-NIX_SHOW_STATS)</span>\
|
||||
If set to `1`, Nix will print some evaluation statistics, such as
|
||||
the number of values allocated.
|
||||
|
||||
- <span id="env-NIX_COUNT_CALLS">[`NIX_COUNT_CALLS`](#env-NIX_COUNT_CALLS)</span>\
|
||||
If set to `1`, Nix will print how often functions were called during
|
||||
Nix expression evaluation. This is useful for profiling your Nix
|
||||
expressions.
|
||||
|
||||
- <span id="env-GC_INITIAL_HEAP_SIZE">[`GC_INITIAL_HEAP_SIZE`](#env-GC_INITIAL_HEAP_SIZE)</span>\
|
||||
If Nix has been configured to use the Boehm garbage collector, this
|
||||
variable sets the initial size of the heap in bytes. It defaults to
|
||||
384 MiB. Setting it to a low value reduces memory consumption, but
|
||||
will increase runtime due to the overhead of garbage collection.
|
||||
|
||||
## XDG Base Directories
|
||||
|
||||
Nix follows the [XDG Base Directory Specification].
|
||||
|
||||
For backwards compatibility, Nix commands will follow the standard only when [`use-xdg-base-directories`] is enabled.
|
||||
[New Nix commands](@docroot@/command-ref/new-cli/nix.md) (experimental) conform to the standard by default.
|
||||
|
||||
The following environment variables are used to determine locations of various state and configuration files:
|
||||
|
||||
- [`XDG_CONFIG_HOME`]{#env-XDG_CONFIG_HOME} (default `~/.config`)
|
||||
- [`XDG_STATE_HOME`]{#env-XDG_STATE_HOME} (default `~/.local/state`)

## Default Nix expression
|
||||
|
||||
The source for the default [Nix expressions](@docroot@/language/index.md) used by [`nix-env`]:
|
||||
|
||||
- `~/.nix-defexpr`
|
||||
- `$XDG_STATE_HOME/nix/defexpr` if [`use-xdg-base-directories`] is set to `true`.
|
||||
|
||||
It is loaded as follows:
|
||||
|
||||
- If the default expression is a file, it is loaded as a Nix expression.
|
||||
- If the default expression is a directory containing a `default.nix` file, that `default.nix` file is loaded as a Nix expression.
|
||||
- If the default expression is a directory without a `default.nix` file, then its contents (both files and subdirectories) are loaded as Nix expressions.
|
||||
The expressions are combined into a single attribute set, each expression under an attribute with the same name as the original file or subdirectory.
|
||||
Subdirectories without a `default.nix` file are traversed recursively in search of more Nix expressions, but the names of these intermediate directories are not added to the attribute paths of the default Nix expression.
|
||||
|
||||
Then, the resulting expression is interpreted like this:
|
||||
|
||||
- If the expression is an attribute set, it is used as the default Nix expression.
|
||||
- If the expression is a function, an empty set is passed as argument and the return value is used as the default Nix expression.
|
||||
|
||||
|
||||
For example, if the default expression contains two files, `foo.nix` and `bar.nix`, then the default Nix expression will be equivalent to
|
||||
|
||||
```nix
|
||||
{
|
||||
foo = import ~/.nix-defexpr/foo.nix;
|
||||
bar = import ~/.nix-defexpr/bar.nix;
|
||||
}
|
||||
```
|
||||
|
||||
The file [`manifest.nix`](@docroot@/command-ref/files/manifest.nix.md) is always ignored.
|
||||
|
||||
The command [`nix-channel`] places a symlink to the user's current [channels profile](@docroot@/command-ref/files/channels.md) in this directory.
|
||||
This makes all subscribed channels available as attributes in the default expression.
|
||||
|
||||
## User channel link
|
||||
|
||||
A symlink that ensures that [`nix-env`] can find your channels:
|
||||
|
||||
- `~/.nix-defexpr/channels`
|
||||
- `$XDG_STATE_HOME/defexpr/channels` if [`use-xdg-base-directories`] is set to `true`.
|
||||
|
||||
This symlink points to:
|
||||
|
||||
- `$XDG_STATE_HOME/profiles/channels` for regular users
|
||||
- `$NIX_STATE_DIR/profiles/per-user/root/channels` for `root`
|
||||
|
||||
In a multi-user installation, you may also have `~/.nix-defexpr/channels_root`, which links to the channels of the root user.[`nix-env`]: ../nix-env.md

`packages.x86_64-linux.hello` and the empty string to

is not "visible" in the profile's symlink tree.

## Profiles
|
||||
|
||||
A directory that contains links to profiles managed by [`nix-env`] and [`nix profile`]:
|
||||
|
||||
- `$XDG_STATE_HOME/nix/profiles` for regular users
|
||||
- `$NIX_STATE_DIR/profiles/per-user/root` if the user is `root`
|
||||
|
||||
A profile is a directory of symlinks to files in the Nix store.
|
||||
|
||||
### Filesystem layout
|
||||
|
||||
Profiles are versioned as follows. When using a profile named *path*, *path* is a symlink to *path*`-`*N*`-link`, where *N* is the version of the profile.
|
||||
In turn, *path*`-`*N*`-link` is a symlink to a path in the Nix store.
|
||||
For example:
|
||||
|
||||
```console
|
||||
$ ls -l ~alice/.local/state/nix/profiles/profile*
|
||||
lrwxrwxrwx 1 alice users 14 Nov 25 14:35 /home/alice/.local/state/nix/profiles/profile -> profile-7-link
|
||||
lrwxrwxrwx 1 alice users 51 Oct 28 16:18 /home/alice/.local/state/nix/profiles/profile-5-link -> /nix/store/q69xad13ghpf7ir87h0b2gd28lafjj1j-profile
|
||||
lrwxrwxrwx 1 alice users 51 Oct 29 13:20 /home/alice/.local/state/nix/profiles/profile-6-link -> /nix/store/6bvhpysd7vwz7k3b0pndn7ifi5xr32dg-profile
|
||||
lrwxrwxrwx 1 alice users 51 Nov 25 14:35 /home/alice/.local/state/nix/profiles/profile-7-link -> /nix/store/mp0x6xnsg0b8qhswy6riqvimai4gm677-profile
|
||||
```
|
||||
|
||||
Each of these symlinks is a root for the Nix garbage collector.
|
||||
|
||||
The contents of the store path corresponding to each version of the
|
||||
profile is a tree of symlinks to the files of the installed packages,
|
||||
e.g.
|
||||
|
||||
```console
|
||||

A symbolic link to the user's current profile:

|
||||
- `$XDG_STATE_HOME/nix/profile` if [`use-xdg-base-directories`] is set to `true`.

||||
|

By default, this symlink points to:
|
||||
|
||||
- `$XDG_STATE_HOME/nix/profiles/profile` for regular users
|
||||
- `$NIX_STATE_DIR/profiles/per-user/root/profile` for `root`
|
||||
|
||||
The `PATH` environment variable should include `/bin` subdirectory of the profile link (e.g. `~/.nix-profile/bin`) for the user environment to be visible to the user.

||||

# Disambiguation
|
||||
|
||||
This man page describes the command `nix-build`, which is distinct from `nix
|
||||
build`. For documentation on the latter, run `nix build --help` or see `man
|
||||
nix3-build`.
|
||||
|
||||
# Description
|
||||
|
||||
The `nix-build` command builds the derivations described by the Nix
|
||||
expressions in *paths*. If the build succeeds, it places a symlink to
|
||||
the result in the current directory. The symlink is called `result`. If
|
||||
there are multiple Nix expressions, or the Nix expressions evaluate to
|
||||
multiple derivations, multiple sequentially numbered symlinks are
|
||||
created (`result`, `result-2`, and so on).
|
||||
|
||||
If no *paths* are specified, then `nix-build` will use `default.nix` in
|
||||
the current directory, if it exists.
|
||||
|
||||
If an element of *paths* 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`.
|
||||
|
||||
`nix-build` is essentially a wrapper around
|
||||
[`nix-instantiate`](nix-instantiate.md) (to translate a high-level Nix
|
||||
expression to a low-level [store derivation]) and [`nix-store
|
||||
--realise`](@docroot@/command-ref/nix-store/realise.md) (to build the store
|
||||
derivation).

||||

||||

|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> The result of the build is automatically registered as a root of the

# Options
|
||||
|
||||
All options not listed here are passed to
|
||||
[`nix-store --realise`](nix-store/realise.md),

- <span id="opt-no-out-link">[`--no-out-link`](#opt-no-out-link)<span>
|
||||
|
||||
Do not create a symlink to the output path. Note that as a result
|
||||
the output does not become a root of the garbage collector, and so
|
||||
might be deleted by `nix-store --gc`.

|
||||
|
||||
Change the name of the symlink to the output path created from

```
|

|

If a derivation has multiple outputs, `nix-build` will build the default
|
||||
(first) output. You can also build all outputs:
|
||||
|
||||
```console
|
||||
$ nix-build '<nixpkgs>' --attr openssl.all
|
||||
```
|
||||
|
||||
This will create a symlink for each output named `result-outputname`.
|
||||
The suffix is omitted if the output name is `out`. So if `openssl` has
|
||||
outputs `out`, `bin` and `man`, `nix-build` will create symlinks
|
||||
`result`, `result-bin` and `result-man`. It’s also possible to build a
|
||||
specific output:
|
||||
|
||||
```console
|
||||
$ nix-build '<nixpkgs>' --attr openssl.man
|
||||
```
|
||||
|
||||
This will create a symlink `result-man`.
|
||||
|
||||
Build a Nix expression given on the command line:
|
||||
|
||||
```console
|
||||
$ nix-build --expr 'with import <nixpkgs> { }; runCommand "foo" { } "echo bar > $out"'
|
||||
$ cat ./result
|
||||
bar

||||
```

# Name

`nix-channel` - manage Nix channels
|

|

# Synopsis
|

|
||||
`nix-channel` {`--add` url [*name*] | `--remove` *name* | `--list` | `--update` [*names…*] | `--list-generations` | `--rollback` [*generation*] }

# Description
|
||||
|
||||
Channels are a mechanism for referencing remote Nix expressions and conveniently retrieving their latest version.
|
||||
|
||||
The moving parts of channels are:
|
||||
- The official channels listed at <https://nixos.org/channels>
|
||||
- The user-specific list of [subscribed channels](#subscribed-channels)
|
||||
- The [downloaded channel contents](#channels)
|
||||
- The [Nix expression search path](@docroot@/command-ref/conf-file.md#conf-nix-path), set with the [`-I` option](#opt-i) or the [`NIX_PATH` environment variable](#env-NIX_PATH)
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> The state of a subscribed channel is external to the Nix expressions relying on it.
|
||||
> This may limit reproducibility.
|
||||
>
|
||||
> Dependencies on other Nix expressions can be declared explicitly with:
|
||||
> - [`fetchurl`](@docroot@/language/builtins.md#builtins-fetchurl), [`fetchTarball`](@docroot@/language/builtins.md#builtins-fetchTarball), or [`fetchGit`](@docroot@/language/builtins.md#builtins-fetchGit) in Nix expressions
|
||||
> - the [`-I` option](@docroot@/command-ref/opt-common.md#opt-I) in command line invocations
|
||||
|
||||
This command has the following operations:
|
||||
|
||||
- `--add` *url* \[*name*\]\
|
||||
Add a channel *name* located at *url* to the list of subscribed channels.
|
||||
If *name* is omitted, default to the last component of *url*, with the suffixes `-stable` or `-unstable` removed.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> `--add` does not automatically perform an update.
|
||||
> Use `--update` explicitly.
|
||||
|
||||
A channel URL must point to a directory containing a file `nixexprs.tar.gz`.
|
||||
At the top level, that tarball must contain a single directory with a `default.nix` file that serves as the channel’s entry point.
|
||||
|
||||
- `--remove` *name*\
|
||||
Remove the channel *name* from the list of subscribed channels.
|
||||
|
||||
- `--list`\
|
||||
Print the names and URLs of all subscribed channels on standard output.
|
||||
|
||||
- `--update` \[*names*…\]\
|
||||
Download the Nix expressions of subscribed channels and create a new generation.
|
||||
Update all channels if none is specified, and only those included in *names* otherwise.
|
||||
|
||||
- `--list-generations`\
|
||||
Prints a list of all the current existing generations for the
|
||||
channel profile.
|
||||
|
||||
Works the same way as
|
||||
```
|
||||
nix-env --profile /nix/var/nix/profiles/per-user/$USER/channels --list-generations
|
||||
```
|
||||
|
||||
- `--rollback` \[*generation*\]\
|
||||
Revert channels to the state before the last call to `nix-channel --update`.
|
||||
Optionally, you can specify a specific channel *generation* number to restore.

||||

$ nix-channel --update
|
||||
$ nix-shell -p hello --run hello
|
||||
hello
|
||||
```
|
||||
|
||||
Revert channel updates using `--rollback`:
|
||||
|
||||
```console
|
||||
$ nix-instantiate --eval '<nixpkgs>' --attr lib.version
|
||||
"22.11pre296212.530a53dcbc9"

# Name

`nix-collect-garbage` - delete unreachable [store objects]
|
||||
|
||||
# Synopsis
|
||||
|
||||
`nix-collect-garbage` [`--delete-old`] [`-d`] [`--delete-older-than` *period*] [`--max-freed` *bytes*] [`--dry-run`]
|
||||
|
||||
# Description
|
||||
|
||||
The command `nix-collect-garbage` is mostly an alias of [`nix-store --gc`](@docroot@/command-ref/nix-store/gc.md).
|
||||
That is, it deletes all unreachable [store objects] in the Nix store to clean up your system.
|
||||
|
||||
However, it provides two additional options,
|
||||
[`--delete-old`](#opt-delete-old) and [`--delete-older-than`](#opt-delete-older-than),
|
||||
which also delete old [profiles], allowing potentially more [store objects] to be deleted because profiles are also garbage collection roots.
|
||||
These options are the equivalent of running
|
||||
[`nix-env --delete-generations`](@docroot@/command-ref/nix-env/delete-generations.md)
|
||||
with various augments on multiple profiles,
|
||||
prior to running `nix-collect-garbage` (or just `nix-store --gc`) without any flags.
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> Deleting previous configurations makes rollbacks to them impossible.
|
||||
|
||||
These flags should be used with care, because they potentially delete generations of profiles used by other users on the system.
|
||||
|
||||
## Locations searched for profiles
|
||||
|
||||
`nix-collect-garbage` cannot know about all profiles; that information doesn't exist.
|
||||
Instead, it looks in a few locations, and acts on all profiles it finds there:
|
||||
|
||||
1. The default profile locations as specified in the [profiles] section of the manual.
|
||||
|
||||

|
||||

|
||||
> Not stable; subject to change
|
||||
>
|
||||
> Do not rely on this functionality; it just exists for migration purposes and is may change in the future.
|
||||
> These deprecated paths remain a private implementation detail of Nix.
|
||||
|
||||
`$NIX_STATE_DIR/profiles` and `$NIX_STATE_DIR/profiles/per-user`.
|
||||
|
||||
With the exception of `$NIX_STATE_DIR/profiles/per-user/root` and `$NIX_STATE_DIR/profiles/default`, these directories are no longer used by other commands.
|
||||
`nix-collect-garbage` looks there anyways in order to clean up profiles from older versions of Nix.
|
||||
|
||||
# Options
|
||||
|
||||
These options are for deleting old [profiles] prior to deleting unreachable [store objects].
|
||||
|
||||
- <span id="opt-delete-old">[`--delete-old`](#opt-delete-old)</span> / `-d`\
|
||||
Delete all old generations of profiles.
|
||||
|
||||
This is the equivalent of invoking `nix-env --delete-generations old` on each found profile.
|
||||
|
||||
- <span id="opt-delete-older-than">[`--delete-older-than`](#opt-delete-older-than)</span> *period*\
|
||||
Delete all generations of profiles older than the specified amount (except for the generations that were active at that point in time).
|
||||
*period* is a value such as `30d`, which would mean 30 days.
|
||||
|
||||
This is the equivalent of invoking [`nix-env --delete-generations <period>`](@docroot@/command-ref/nix-env/delete-generations.md#generations-time) on each found profile.
|
||||
See the documentation of that command for additional information about the *period* argument.

|

|

# Description
|
||||
|
||||
`nix-copy-closure` gives you an easy and efficient way to exchange
|
||||
software between machines. Given one or more Nix store _paths_ on the
|
||||
local machine, `nix-copy-closure` computes the closure of those paths
|
||||
(i.e. all their dependencies in the Nix store), and copies all paths
|
||||
in the closure to the remote machine via the `ssh` (Secure Shell)
|
||||
command. With the `--from` option, the direction is reversed: the
|
||||
closure of _paths_ on a remote machine is copied to the Nix store on
|
||||
the local machine.
|
||||
|
||||
This command is efficient because it only sends the store paths
|
||||
that are missing on the target machine.
|
||||
|
||||
Since `nix-copy-closure` calls `ssh`, you may be asked to type in the
|
||||
appropriate password or passphrase. In fact, you may be asked _twice_
|
||||
because `nix-copy-closure` currently connects twice to the remote
|
||||
machine, first to get the set of paths missing on the target machine,
|
||||
and second to send the dump of those paths. When using public key
|
||||
authentication, you can avoid typing the passphrase with `ssh-agent`.
|
||||
|
||||
# Options
|
||||
|
||||
- `--to`\
|
||||
Copy the closure of _paths_ from the local Nix store to the Nix
|
||||
store on _machine_. This is the default.
|
||||
|
||||
- `--from`\
|
||||
Copy the closure of _paths_ from the Nix store on _machine_ to the
|
||||
local Nix store.
|
||||
|
||||
- `--gzip`\
|
||||
Enable compression of the SSH connection.
|
||||
|
||||
- `--include-outputs`\
|
||||
Also copy the outputs of [store derivation]s included in the closure.
|
||||
|
||||
[store derivation]: ../glossary.md#gloss-store-derivation
|
||||
|
||||
- `--use-substitutes` / `-s`\
|
||||
Attempt to download missing paths on the target machine using Nix’s
|
||||
substitute mechanism. Any paths that cannot be substituted on the
|
||||
target are still copied normally from the source. This is useful,
|
||||
for instance, if the connection between the source and target
|
||||
machine is slow, but the connection between the target machine and
|
||||
`nixos.org` (the default binary cache server) is
|
||||
fast.
|
||||
|
||||

|

# Description
|

The command `nix-env` is used to manipulate Nix user environments. User
|

environments are sets of software packages available to a user at some
|
||||
point in time. In other words, they are a synthesised view of the
|
||||
programs available in the Nix store. There may be many user
|
||||
environments: different users can have different environments, and
|
||||
individual users can switch between different environments.
|
||||
|
||||
`nix-env` takes exactly one *operation* flag which indicates the
|
||||
subcommand to be performed. The following operations are available:
|
||||
|
||||
- [`--install`](./nix-env/install.md)
|
||||
- [`--upgrade`](./nix-env/upgrade.md)
|

# Selectors
|
||||
|
||||
Several commands, such as `nix-env --query ` and `nix-env --install `, take a list of
|
||||
arguments that specify the packages on which to operate. These are
|
||||
extended regular expressions that must match the entire name of the
|
||||
package. (For details on regular expressions, see **regex**(7).) The match is
|
||||
case-sensitive. The regular expression can optionally be followed by a
|
||||
dash and a version number; if omitted, any version of the package will
|
||||
match. Here are some examples:
|
||||
|
||||
- `firefox`\
|
||||
Matches the package name `firefox` and any version.
|
||||
|
||||
- `firefox-32.0`\
|
||||
Matches the package name `firefox` and version `32.0`.
|
||||
|
||||
- `gtk\\+`\
|
||||
Matches the package name `gtk+`. The `+` character must be escaped
|
||||
using a backslash to prevent it from being interpreted as a
|
||||
quantifier, and the backslash must be escaped in turn with another
|
||||
backslash to ensure that the shell passes it on.
|
||||
|
||||
- `.\*`\
|
||||
Matches any package name. This is the default for most commands.
|
||||
|
||||
- `'.*zip.*'`\
|
||||
Matches any package name containing the string `zip`. Note the dots:
|
||||
`'*zip*'` does not work, because in a regular expression, the
|
||||
character `*` is interpreted as a quantifier.
|
||||
|
||||
- `'.*(firefox|chromium).*'`\
|
||||
Matches any package name containing the strings `firefox` or
|
||||
`chromium`.

A list of generation numbers, each one a separate command-line argument.
|

Delete exactly the profile generations given by their generation number.
|
||||
Deleting the current generation is not allowed.
|
||||
|
||||
- The special value <span id="generations-old">`old`</span>
|
||||
|
||||
Delete all generations except the current one.
|
||||
|
||||
> **WARNING**
|
||||
>
|
||||
> Older *and newer* generations will be deleted by this operation.
|
||||
>
|
||||
> One might expect this to just delete older generations than the curent one, but that is only true if the current generation is also the latest.
|
||||
> Because one can roll back to a previous generation, it is possible to have generations newer than the current one.
|
||||
> They will also be deleted.
|
||||
|
||||
- <span id="generations-time">`<number>d`</span>:\
|
||||
The last *number* days
|
||||
|
||||
*Example*: `30d`
|
||||
|
||||
Delete all generations created more than *number* days ago, except the most recent one of them.
|
||||
This allows rolling back to generations that were available within the specified period.
|
||||
|
||||
- <span id="generations-count">`+<number>`</span>:\
|
||||
The last *number* generations up to the present
|
||||
|
||||
*Example*: `+5`
|
||||
|
||||
Keep the last *number* generations, along with any newer than current.
|
||||
|
||||
Periodically deleting old generations is important to make garbage collection
|
||||
effective.
|
||||
The is because profiles are also garbage collection roots — any [store object] reachable from a profile is "alive" and ineligible for deletion.

$ nix-env --delete-generations 3 4 8
|
||||
```
|
||||
|
||||
Delete the generations numbered 3, 4, and 8, so long as the current active generation is not any of those.
|
||||
|
||||
## Keep most-recent by count (number of generations)
|
||||
|
||||
```console
|
||||
$ nix-env --delete-generations +5
|
||||
```
|
||||
|
||||
Suppose `30` is the current generation, and we currently have generations numbered `20` through `32`.
|
||||
|
||||
Then this command will delete generations `20` through `25` (`<= 30 - 5`),
|
||||
and keep generations `26` through `31` (`> 30 - 5`).
|
||||
|
||||
## Keep most-recent by time (number of days)
|
||||
|
||||
```console
|
||||
$ nix-env --delete-generations 30d
|
||||
```
|
||||
|
||||
This command will delete all generations older than 30 days, except for the generation that was active 30 days ago (if it currently exists).

# 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 `5`.
|
||||
|
||||
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 --install
|
||||
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 --query --available --attr-path `.
|
||||
|
||||
- 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 --uninstall '.*'` 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 --install --attr gcc40mips
|
||||
installing `gcc-4.0.2'
|
||||
$ nix-env --install --attr 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 --file ~/foo.nix --install '.*'
|
||||
```
|
||||
|
||||
To copy the store path with symbolic name `gcc` from another profile:
|
||||
|
||||
```console
|
||||
$ nix-env --install --from-profile /nix/var/nix/profiles/foo gcc
|
||||
```
|
||||
|
||||
To install a specific [store derivation] (typically created by
|
||||
`nix-instantiate`):
|
||||
|
||||
```console
|
||||
$ nix-env --install /nix/store/fibjb1bfbpm5mrsxc4mh2d8n37sxh91i-gcc-3.4.3.drv
|
||||
```
|
||||
|
||||
To install a specific output path:
|
||||
|
||||
```console
|
||||
$ nix-env --install /nix/store/y3cgx0xj1p4iv9x0pnnmdhr8iyg741vk-gcc-3.4.3
|
||||
```
|
||||
|
||||
To install from a Nix expression specified on the command-line:
|
||||
|
||||
```console
|
||||
$ nix-env --file ./foo.nix --install --expr \
|
||||
'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 --file '<nixpkgs>' --install --attr 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 --file https://github.com/NixOS/nixpkgs/archive/nixos-14.12.tar.gz --install --attr firefox

# Options
|
||||
|
||||
The following options are allowed for all `nix-env` operations, but may not always have an effect.
|
||||
|
||||
- `--file` / `-f` *path*\
|
||||
Specifies the Nix expression (designated below as the *active Nix
|
||||
expression*) used by the `--install`, `--upgrade`, and `--query
|
||||
--available` operations to obtain derivations. The default is
|
||||
`~/.nix-defexpr`.
|
||||
|
||||
If the argument starts with `http://` or `https://`, it is
|
||||
interpreted as the URL of a tarball that will be downloaded and
|
||||
unpacked to a temporary location. The tarball must include a single
|
||||
top-level directory containing at least a file named `default.nix`.
|
||||
|
||||
- `--profile` / `-p` *path*\
|
||||
Specifies the profile to be used by those operations that operate on
|
||||
a profile (designated below as the *active profile*). A profile is a
|
||||
sequence of user environments called *generations*, one of which is
|
||||
the *current generation*.
|
||||
|
||||
- `--dry-run`\
|
||||
For the `--install`, `--upgrade`, `--uninstall`,
|
||||
`--switch-generation`, `--delete-generations` and `--rollback`
|
||||
operations, this flag will cause `nix-env` to print what *would* be
|
||||
done if this flag had not been specified, without actually doing it.
|

`--dry-run` also prints out which paths will be
|
||||
[substituted](@docroot@/glossary.md) (i.e., downloaded) and which paths
|
||||
will be built from source (because no substitute is available).
|
||||
|
||||
- `--system-filter` *system*\
|
||||
By default, operations such as `--query
|
||||
--available` show derivations matching any platform. This option
|
||||
allows you to use derivations for the specified platform *system*.

# Description
|

|

The query operation displays information about either the store paths
|

that are installed in the current generation of the active profile

(`--installed`), or the derivations that are available for installation
|
||||
in the active Nix expression (`--available`). It only prints information
|

about derivations whose symbolic name matches one of *names*.
|

|
||||
The derivations are sorted by their `name` attributes.

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

`nix-env --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.

```console

|
||||
After this, `nix-env --upgrade ` will ignore Firefox.
|
||||
|
||||
To disable the currently installed Firefox, then install a new Firefox
|
||||
while the old remains part of the profile:

|
||||
and `/nix/store/...-firefox-2.0.0.9/bin/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.
|
||||
|
||||
# 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

|
||||
upgrading `gcc-3.3.1' to `gcc-3.4'
|
||||
```
|
||||
|
||||
When there are no updates available, nothing will happen:
|
||||
|
||||
```console
|
||||
$ nix-env --upgrade --attr 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 --upgrade 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 --upgrade
|
||||
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

|
||||
|
||||
# Description
|
||||
|
||||
The command `nix-hash` computes the cryptographic hash of the contents
|
||||
of each *path* and prints it on standard output. By default, it computes
|
||||
an MD5 hash, but other hash algorithms are available as well. The hash
|
||||
is printed in hexadecimal. To generate the same hash as
|
||||
`nix-prefetch-url` you have to specify multiple arguments, see below for
|
||||
an example.
|
||||
|
||||
The hash is computed over a *serialisation* of each path: a dump of
|
||||
the file system tree rooted at the path. This allows directories and
|
||||
symlinks to be hashed as well as regular files. The dump is in the
|
||||
*NAR format* produced by [`nix-store
|
||||
--dump`](@docroot@/command-ref/nix-store/dump.md). Thus, `nix-hash path`
|
||||
yields the same cryptographic hash as `nix-store --dump path |
|
||||
md5sum`.
|
||||
|
||||
# Options
|
||||
|
||||
- `--flat`\
|
||||
Print the cryptographic hash of the contents of each regular file
|
||||
*path*. That is, do not compute the hash over the dump of *path*.
|
||||
The result is identical to that produced by the GNU commands
|
||||
`md5sum` and `sha1sum`.
|
||||
|
||||
- `--base16`\
|
||||
Print the hash in a hexadecimal representation (default).
|
||||
|
||||
- `--base32`\
|
||||
Print the hash in a base-32 representation rather than hexadecimal.
|
||||
This base-32 representation is more compact and can be used in Nix
|
||||
expressions (such as in calls to `fetchurl`).
|
||||
|
||||
- `--base64`\
|
||||
Similar to --base32, but print the hash in a base-64 representation,
|
||||
which is more compact than the base-32 one.
|
||||
|
||||
- `--sri`\
|
||||
Print the hash in SRI format with base-64 encoding.
|
||||
The type of hash algorithm will be prepended to the hash string,
|
||||
followed by a hyphen (-) and the base-64 hash body.
|
||||
|
||||
- `--truncate`\
|
||||
Truncate hashes longer than 160 bits (such as SHA-256) to 160 bits.
|
||||
|
||||
- `--type` *hashAlgo*\
|
||||
Use the specified cryptographic hash algorithm, which can be one of
|
||||
`md5`, `sha1`, `sha256`, and `sha512`.
|
||||
|
||||
- `--to-base16`\
|
||||
Don’t hash anything, but convert the base-32 hash representation
|
||||
*hash* to hexadecimal.
|
||||
|
||||
- `--to-base32`\
|
||||
Don’t hash anything, but convert the hexadecimal hash representation
|
||||
*hash* to base-32.
|
||||
|
||||
- `--to-base64`\
|
||||
Don’t hash anything, but convert the hexadecimal hash representation
|
||||
*hash* to base-64.
|
||||
|
||||
- `--to-sri`\
|
||||
Don’t hash anything, but convert the hexadecimal hash representation
|
||||
*hash* to SRI.
|
||||
|
||||
# Examples
|
||||
|
||||
Computing the same hash as `nix-prefetch-url`:
|
||||
|
||||

|
||||

# Description
|
||||
|
||||
The command `nix-instantiate` produces [store derivation]s from (high-level) Nix expressions.
|
||||
It evaluates the Nix expressions in each of *files* (which defaults to
|
||||
*./default.nix*). Each top-level expression should evaluate to a
|
||||
derivation, a list of derivations, or a set of derivations. The paths
|
||||
of the resulting store derivations are printed on standard output.
|
||||
|
||||
[store derivation]: ../glossary.md#gloss-store-derivation
|
||||
|
||||
If *files* is the character `-`, then a Nix expression will be read from
|
||||
standard input.
|
||||
|
||||
# Options
|
||||
|
||||
- `--add-root` *path*\
|
||||
See the [corresponding option](nix-store.md) in `nix-store`.
|
||||
|
||||
- `--parse`\
|
||||
Just parse the input files, and print their abstract syntax trees on
|
||||
standard output in ATerm format.
|
||||
|
||||
- `--eval`\
|
||||
Just parse and evaluate the input files, and print the resulting
|
||||
values on standard output. No instantiation of store derivations
|
||||
takes place.
|
||||
|
||||
- `--find-file`\
|
||||
Look up the given files in Nix’s search path (as specified by the
|
||||
`NIX_PATH` environment variable). If found, print the corresponding
|
||||
absolute paths on standard output. For instance, if `NIX_PATH` is
|
||||
`nixpkgs=/home/alice/nixpkgs`, then `nix-instantiate --find-file
|
||||
nixpkgs/default.nix` will print `/home/alice/nixpkgs/default.nix`.
|
||||
|
||||
- `--strict`\
|
||||
When used with `--eval`, recursively evaluate list elements and
|
||||
attributes. Normally, such sub-expressions are left unevaluated
|
||||
(since the Nix language is lazy).
|
||||
|
||||
> **Warning**
|
||||
>
|
||||
> This option can cause non-termination, because lazy data
|
||||
> structures can be infinitely large.
|
||||
|
||||
- `--json`\
|
||||
When used with `--eval`, print the resulting value as an JSON
|
||||
representation of the abstract syntax tree rather than as an ATerm.
|
||||
|
||||
- `--xml`\
|
||||
When used with `--eval`, print the resulting value as an XML
|
||||
representation of the abstract syntax tree rather than as an ATerm.
|
||||
The schema is the same as that used by the [`toXML`
|
||||
built-in](../language/builtins.md).
|
||||
|
||||
- `--read-write-mode`\
|
||||
When used with `--eval`, perform evaluation in read/write mode so
|
||||
nix language features that require it will still work (at the cost
|
||||
of needing to do instantiation of every evaluated derivation). If
|
||||
this option is not enabled, there may be uninstantiated store paths
|
||||
in the final output.

||||

||||

|
||||
|
||||
{{#include ./env-common.md}}
|
||||
|
||||
# Examples
|
||||
|
||||
Instantiate [store derivation]s from a Nix expression, and build them using `nix-store`:
|
||||
|
||||
```console
|
||||
$ nix-instantiate test.nix (instantiate)
|
||||
/nix/store/cigxbmvy6dzix98dxxh9b6shg7ar5bvs-perl-BerkeleyDB-0.26.drv
|
||||
|
||||
$ nix-store --realise $(nix-instantiate test.nix) (build)
|
||||
...
|
||||
/nix/store/qhqk4n8ci095g3sdp93x7rgwyh9rdvgk-perl-BerkeleyDB-0.26 (output path)
|
||||
|
||||
$ ls -l /nix/store/qhqk4n8ci095g3sdp93x7rgwyh9rdvgk-perl-BerkeleyDB-0.26
|
||||
dr-xr-xr-x 2 eelco users 4096 1970-01-01 01:00 lib
|
||||
...
|
||||
```
|
||||
|
||||
You can also give a Nix expression on the command line:
|
||||
|
||||
```console
|
||||
$ nix-instantiate --expr 'with import <nixpkgs> { }; hello'
|
||||
/nix/store/j8s4zyv75a724q38cb0r87rlczaiag4y-hello-2.8.drv
|
||||
```
|
||||
|
||||
This is equivalent to:
|
||||
|
||||
```console
|
||||
$ nix-instantiate '<nixpkgs>' --attr hello
|
||||
```
|
||||
|
||||
Parsing and evaluating Nix expressions:
|
||||
|
||||
```console
|
||||
$ nix-instantiate --parse --expr '1 + 2'
|
||||
1 + 2
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-instantiate --eval --expr '1 + 2'
|
||||
3
|
||||
```
|
||||
|
||||
```console
|
||||
$ nix-instantiate --eval --xml --expr '1 + 2'
|
||||
<?xml version='1.0' encoding='utf-8'?>
|
||||
<expr>
|
||||
<int value="3" />
|
||||
</expr>
|
||||
```
|
||||
|
||||
The difference between non-strict and strict evaluation:
|
||||
|
||||
```console
|
||||
$ nix-instantiate --eval --xml --expr 'rec { x = "foo"; y = x; }'
|
||||
...
|
||||
<attr name="x">
|
||||
<string value="foo" />
|
||||
</attr>
|
||||
<attr name="y">
|
||||
<unevaluated />
|
||||
</attr>
|
||||
...
|
||||
```
|
||||
|
||||
Note that `y` is left unevaluated (the XML representation doesn’t
|
||||
attempt to show non-normal forms).
|
||||
|
||||
```console
|
||||
$ nix-instantiate --eval --xml --strict --expr 'rec { x = "foo"; y = x; }'
|
||||
...
|
||||
<attr name="x">
|
||||
<string value="foo" />
|
||||
</attr>
|
||||
<attr name="y">
|
||||
<string value="foo" />
|
||||
</attr>
|
||||

`nix-prefetch-url` - copy a file from a URL into the store and print its hash
|
||||
|

# Synopsis
|
||||

`nix-prefetch-url` *url* [*hash*]
|
||||
[`--type` *hashAlgo*]

|

# Description
|
||||
|
||||
The command `nix-prefetch-url` downloads the file referenced by the URL
|
||||
*url*, prints its cryptographic hash, and copies it into the Nix store.
|
||||
The file name in the store is `hash-baseName`, where *baseName* is
|
||||
everything following the final slash in *url*.
|
||||
|
||||
This command is just a convenience for Nix expression writers. Often a
|
||||
Nix expression fetches some source distribution from the network using
|
||||
the `fetchurl` expression contained in Nixpkgs. However, `fetchurl`
|
||||
requires a cryptographic hash. If you don't know the hash, you would
|
||||
have to download the file first, and then `fetchurl` would download it
|
||||
again when you build your Nix expression. Since `fetchurl` uses the same
|
||||
name for the downloaded file as `nix-prefetch-url`, the redundant
|
||||
download can be avoided.
|
||||
|
||||
If *hash* is specified, then a download is not performed if the Nix
|
||||
store already contains a file with the same hash and base name.
|
||||
Otherwise, the file is downloaded, and an error is signaled if the
|
||||
actual hash of the file does not match the specified hash.
|
||||
|
||||
This command prints the hash on standard output.
|
||||
The hash is printed using base-32 unless `--type md5` is specified,
|
||||
in which case it's printed using base-16.
|
||||
Additionally, if the option `--print-path` is used,
|
||||
the path of the downloaded file in the Nix store is also printed.
|
||||
|
||||
# Options
|
||||
|
||||
- `--type` *hashAlgo*\
|
||||
Use the specified cryptographic hash algorithm,
|
||||
which can be one of `md5`, `sha1`, `sha256`, and `sha512`.
|
||||
The default is `sha256`.
|
||||
|
||||
- `--print-path`\
|
||||
Print the store path of the downloaded file on standard output.
|
||||
|
||||
- `--unpack`\
|
||||
Unpack the archive (which must be a tarball or zip file) and add the
|
||||
result to the Nix store. The resulting hash can be used with
|
||||
functions such as Nixpkgs’s `fetchzip` or `fetchFromGitHub`.
|
||||
|
||||
- `--executable`\
|
||||
Set the executable bit on the downloaded file.
|
||||
|
||||
- `--name` *name*\
|
||||
Override the name of the file in the Nix store. By default, this is
|
||||
`hash-basename`, where *basename* is the last component of *url*.
|
||||
Overriding the name is necessary when *basename* contains characters
|
||||
that are not allowed in Nix store paths.

# Disambiguation
|
||||
|
||||
This man page describes the command `nix-shell`, which is distinct from `nix
|
||||
shell`. For documentation on the latter, run `nix shell --help` or see `man
|
||||
nix3-shell`.
|
||||
|
||||
# Description
|
||||
|
||||
The command `nix-shell` will build the dependencies of the specified
|
||||
derivation, but not the derivation itself. It will then start an
|
||||
interactive shell in which all environment variables defined by the
|
||||
derivation *path* have been set to their corresponding values, and the
|
||||
script `$stdenv/setup` has been sourced. This is useful for reproducing
|
||||
the environment of a derivation for development.
|
||||
|
||||
If *path* is not given, `nix-shell` defaults to `shell.nix` if it
|
||||
exists, and `default.nix` otherwise.
|
||||
|
||||
If *path* starts with `http://` or `https://`, it is interpreted as the
|
||||
URL of a tarball that will be downloaded and unpacked to a temporary
|
||||
location. The tarball must include a single top-level directory
|
||||
containing at least a file named `default.nix`.
|
||||
|
||||
If the derivation defines the variable `shellHook`, it will be run
|
||||
after `$stdenv/setup` has been sourced. Since this hook is not executed
|
||||
by regular Nix builds, it allows you to perform initialisation specific
|
||||
to `nix-shell`. For example, the derivation attribute
|
||||
|
||||
```nix
|
||||
shellHook =
|
||||
''
|
||||
echo "Hello shell"
|
||||
export SOME_API_TOKEN="$(cat ~/.config/some-app/api-token)"
|
||||
'';
|
||||
```
|
||||
|
||||
will cause `nix-shell` to print `Hello shell` and set the `SOME_API_TOKEN`
|
||||
environment variable to a user-configured value.
|
||||
|
||||
# Options
|
||||
|
||||
All options not listed here are passed to `nix-store
|
||||
--realise`, except for `--arg` and `--attr` / `-A` which are passed to
|
||||
`nix-instantiate`.
|
||||
|
||||
- `--command` *cmd*\
|
||||
In the environment of the derivation, run the shell command *cmd*.
|
||||
This command is executed in an interactive shell. (Use `--run` to
|
||||
use a non-interactive shell instead.) However, a call to `exit` is
|
||||
implicitly added to the command, so the shell will exit after
|
||||
running the command. To prevent this, add `return` at the end;
|
||||
e.g. `--command "echo Hello; return"` will print `Hello` and then
|
||||
drop you into the interactive shell. This can be useful for doing
|
||||
any additional initialisation.
|
||||
|
||||
- `--run` *cmd*\
|
||||
Like `--command`, but executes the command in a non-interactive
|
||||
shell. This means (among other things) that if you hit Ctrl-C while
|
||||
the command is running, the shell exits.
|
||||
|
||||
- `--exclude` *regexp*\
|
||||
Do not build any dependencies whose store path matches the regular
|
||||
expression *regexp*. This option may be specified multiple times.
|
||||
|
||||
- `--pure`\
|
||||
If this flag is specified, the environment is almost entirely
|
||||
cleared before the interactive shell is started, so you get an
|
||||
environment that more closely corresponds to the “real” Nix build. A
|
||||
few variables, in particular `HOME`, `USER` and `DISPLAY`, are
|
||||
retained.
|
||||
|
||||
- `--packages` / `-p` *packages*…\
|
||||
Set up an environment in which the specified packages are present.
|
||||
The command line arguments are interpreted as attribute names inside
|
||||
the Nix Packages collection. Thus, `nix-shell --packages libjpeg openjdk`
|
||||
will start a shell in which the packages denoted by the attribute
|
||||
names `libjpeg` and `openjdk` are present.
|
||||
|
||||
- `-i` *interpreter*\
|
||||
The chained script interpreter to be invoked by `nix-shell`. Only
|
||||
applicable in `#!`-scripts (described below).
|
||||
|
||||
- `--keep` *name*\
|
||||
When a `--pure` shell is started, keep the listed environment
|
||||
variables.
|
||||
|
||||
{{#include ./opt-common.md}}
|
||||
|
||||
# Environment variables
|
||||
|
||||
- `NIX_BUILD_SHELL`\
|
||||
Shell used to start the interactive environment. Defaults to the
|
||||
`bash` found in `<nixpkgs>`, falling back to the `bash` found in
|
||||
`PATH` if not found.
|
||||
|
||||
{{#include ./env-common.md}}
|
||||
|
||||
# Examples
|
||||
|
||||
To build the dependencies of the package Pan, and start an interactive
|
||||
shell in which to build it:
|
||||
|
||||
```console
|
||||
$ nix-shell '<nixpkgs>' --attr pan
|
||||
[nix-shell]$ eval ${unpackPhase:-unpackPhase}
|
||||
[nix-shell]$ cd $sourceRoot
|
||||
[nix-shell]$ eval ${patchPhase:-patchPhase}
|
||||
[nix-shell]$ eval ${configurePhase:-configurePhase}
|
||||
[nix-shell]$ eval ${buildPhase:-buildPhase}
|
||||
[nix-shell]$ ./pan/gui/pan
|
||||
```
|
||||
|
||||
The reason we use form `eval ${configurePhase:-configurePhase}` here is because
|
||||
those packages that override these phases do so by exporting the overridden
|
||||
values in the environment variable of the same name.
|
||||
Here bash is being told to either evaluate the contents of 'configurePhase',
|
||||
if it exists as a variable, otherwise evaluate the configurePhase function.
|
||||
|
||||
To clear the environment first, and do some additional automatic
|
||||
initialisation of the interactive shell:
|
||||
|
||||
```console
|
||||
$ nix-shell '<nixpkgs>' --attr pan --pure \
|
||||
--command 'export NIX_DEBUG=1; export NIX_CORES=8; return'
|
||||
```
|
||||
|
||||
Nix expressions can also be given on the command line using the `-E` and
|
||||
`-p` flags. For instance, the following starts a shell containing the
|
||||
packages `sqlite` and `libX11`:
|
||||
|
||||
```console
|
||||
$ nix-shell --expr 'with import <nixpkgs> { }; runCommand "dummy" { buildInputs = [ sqlite xorg.libX11 ]; } ""'
|
||||
```
|
||||
|
||||
A shorter way to do the same is:
|
||||
|
||||
```console
|
||||
$ nix-shell --packages sqlite xorg.libX11
|
||||
[nix-shell]$ echo $NIX_LDFLAGS
|
||||
… -L/nix/store/j1zg5v…-sqlite-3.8.0.2/lib -L/nix/store/0gmcz9…-libX11-1.6.1/lib …
|
||||
```
|
||||
|
||||
Note that `-p` accepts multiple full nix expressions that are valid in
|
||||
the `buildInputs = [ ... ]` shown above, not only package names. So the
|
||||
following is also legal:
|
||||
|
||||
```console
|
||||
$ nix-shell --packages sqlite 'git.override { withManual = false; }'
|
||||
```
|
||||
|
||||
The `-p` flag looks up Nixpkgs in the Nix search path. You can override
|
||||
it by passing `-I` or setting `NIX_PATH`. For example, the following
|
||||
gives you a shell containing the Pan package from a specific revision of
|
||||
Nixpkgs:
|
||||
|
||||
```console
|
||||
$ nix-shell --packages pan -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/8a3eea054838b55aca962c3fbde9c83c102b8bf2.tar.gz
|
||||
|
||||
[nix-shell:~]$ pan --version
|
||||
Pan 0.139
|
||||
```
|
||||
|
||||
# Use as a `#!`-interpreter
|
||||
|
||||
You can use `nix-shell` as a script interpreter to allow scripts written
|
||||
in arbitrary languages to obtain their own dependencies via Nix. This is
|
||||
done by starting the script with the following lines:
|
||||
|
||||
```bash
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell -i real-interpreter --packages packages
|
||||
```
|
||||
|
||||
where *real-interpreter* is the “real” script interpreter that will be
|
||||
invoked by `nix-shell` after it has obtained the dependencies and
|
||||
initialised the environment, and *packages* are the attribute names of
|
||||
the dependencies in Nixpkgs.
|
||||
|
||||
The lines starting with `#! nix-shell` specify `nix-shell` options (see
|
||||
above). Note that you cannot write `#! /usr/bin/env nix-shell -i ...`
|
||||
because many operating systems only allow one argument in `#!` lines.
|
||||
|
||||
For example, here is a Python script that depends on Python and the
|
||||
`prettytable` package:
|
||||
|
||||
```python
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell -i python --packages python pythonPackages.prettytable
|
||||
|
||||
import prettytable
|
||||
|
||||
# Print a simple table.
|
||||
t = prettytable.PrettyTable(["N", "N^2"])
|
||||
for n in range(1, 10): t.add_row([n, n * n])
|
||||
print t
|
||||
```
|
||||
|
||||
Similarly, the following is a Perl script that specifies that it
|
||||
requires Perl and the `HTML::TokeParser::Simple` and `LWP` packages:
|
||||
|
||||
```perl
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell -i perl --packages perl perlPackages.HTMLTokeParserSimple perlPackages.LWP
|
||||
|
||||
use HTML::TokeParser::Simple;
|
||||
|
||||
# Fetch nixos.org and print all hrefs.
|
||||
my $p = HTML::TokeParser::Simple->new(url => 'http://nixos.org/');
|
||||
|
||||
while (my $token = $p->get_tag("a")) {
|
||||
my $href = $token->get_attr("href");
|
||||
print "$href\n" if $href;
|
||||
}
|
||||
```
|
||||
|
||||
Sometimes you need to pass a simple Nix expression to customize a
|
||||
package like Terraform:
|
||||
|
||||
```bash
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell -i bash --packages "terraform.withPlugins (plugins: [ plugins.openstack ])"
|
||||
|
||||
terraform apply
|
||||
```
|
||||
|
||||
> **Note**
|
||||
>
|
||||
> You must use double quotes (`"`) when passing a simple Nix expression
|
||||
> in a nix-shell shebang.
|
||||
|
||||
Finally, using the merging of multiple nix-shell shebangs the following
|
||||
Haskell script uses a specific branch of Nixpkgs/NixOS (the 20.03 stable
|
||||
branch):
|
||||
|
||||
```haskell
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell -i runghc --packages "haskellPackages.ghcWithPackages (ps: [ps.download-curl ps.tagsoup])"
|
||||
#! nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/nixos-20.03.tar.gz
|
||||
|
||||
import Network.Curl.Download
|
||||
import Text.HTML.TagSoup
|
||||
import Data.Either
|
||||
import Data.ByteString.Char8 (unpack)
|
||||
|
||||
-- Fetch nixos.org and print all hrefs.
|
||||
main = do
|
||||
resp <- openURI "https://nixos.org/"
|
||||
let tags = filter (isTagOpenName "a") $ parseTags $ unpack $ fromRight undefined resp
|
||||
let tags' = map (fromAttrib "href") tags
|
||||
mapM_ putStrLn $ filter (/= "") tags'
|
||||
```
|
||||
|
||||
If you want to be even more precise, you can specify a specific revision
|
||||
of Nixpkgs:
|
||||
|
||||
#! nix-shell -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/0672315759b3e15e2121365f067c1c8c56bb4722.tar.gz
|
||||
|
||||
The examples above all used `-p` to get dependencies from Nixpkgs. You
|
||||
can also use a Nix expression to build your own dependencies. For
|
||||
example, the Python example could have been written as:
|
||||
|
||||
```python
|
||||
#! /usr/bin/env nix-shell
|
||||
#! nix-shell deps.nix -i python
|
||||
```
|
||||
|
||||
where the file `deps.nix` in the same directory as the `#!`-script
|
||||
contains:
|
||||
|
||||
```nix
|
||||
with import <nixpkgs> {};

# 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).

`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 --query
|
||||
--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

## Synopsis

|

`nix-store` `--export` *paths…*
|
||||
|
||||
## Description
|
||||
|
||||
The operation `--export` writes a serialisation of the specified store

paths to standard output in a format that can be imported into another
|
||||
Nix store with `nix-store --import`. This is like `nix-store
|

--dump`, except that the NAR archive produced by that command doesn’t
|
||||
contain the necessary meta-information to allow it to be imported into
|
||||
another Nix store (namely, the set of references of the path).
|
||||
|
||||
This command does not produce a *closure* of the specified paths, so if
|
||||
a store path references other store paths that are missing in the target
|
||||
Nix store, the import will fail.

`nix-store` `--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.

`cache.example.org`) with a suffix denoting the number of the key

(to be incremented every time you need to revoke a key).
|

2. The file name where the secret key is to be stored.

# 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 --realise ...
|
||||
|
||||
$ 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).
