# 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.

Previously, if an element of a list or attribute set threw an error while
|
||||
evaluating, `nix repl` would print the entire error (including source location
|
||||
information) inline. This output was clumsy and difficult to parse:
|
||||
|
||||
```
|
||||
nix-repl> { err = builtins.throw "uh oh!"; }
|
||||
{ err = «error:
|
||||

|

1| { err = builtins.throw "uh oh!"; }
|
||||
| ^
|
||||
|
||||
error: uh oh!»; }
|
||||
```
|
||||
|
||||
Now, only the error message is displayed, making the output much more readable.
|

```

nix-repl> { err = builtins.throw "uh oh!"; }
|

{ err = «error: uh oh!»; }
|

```

locations and (if applicable) a stack trace are printed, just like you'd expect:

Add a new `eval-system` option.
|
||||
Unlike `system`, it just overrides the value of `builtins.currentSystem`.
|
||||
This is more useful than overriding `system`, because you can build these derivations on remote builders which can work on the given system.
|
||||
In contrast, `system` also effects scheduling which will cause Lix to build those derivations locally even if that doesn't make sense.
|
||||
|
||||
`eval-system` only takes effect if it is non-empty.
|
||||
If empty (the default) `system` is used as before, so there is no breakage.

The interface for creating and updating lock files has been overhauled:
|
||||
|
||||
- [`nix flake lock`](@docroot@/command-ref/new-cli/nix3-flake-lock.md) only creates lock files and adds missing inputs now.
|
||||
It will *never* update existing inputs.
|
||||
|
||||
- [`nix flake update`](@docroot@/command-ref/new-cli/nix3-flake-update.md) does the same, but *will* update inputs.
|
||||
- Passing no arguments will update all inputs of the current flake, just like it already did.
|
||||
- Passing input names as arguments will ensure only those are updated. This replaces the functionality of `nix flake lock --update-input`
|
||||
- To operate on a flake outside the current directory, you must now pass `--flake path/to/flake`.
|
||||
|
||||
- The flake-specific flags `--recreate-lock-file` and `--update-input` have been removed from all commands operating on installables.

Using `:doc` in the REPL now supports showing documentation comments when defined on a function.
|
||||
|
||||
Previously this was only able to document builtins, however it now will show comments defined on a lambda as well.
|
||||
|
||||
This support is experimental and relies on an embedded version of [nix-doc](https://github.com/lf-/nix-doc).
|
||||
|
||||
The logic also supports limited Markdown formatting of doccomments and should easily support any [RFC 145](https://github.com/NixOS/rfcs/blob/master/rfcs/0145-doc-strings.md)
|
||||
compatible documentation comments in addition to simple commented documentation.

A `repl-overlays` option has been added, which specifies files that can overlay
|

and modify the top-level bindings in `nix repl`. For example, with the
|

following contents in `~/.config/nix/repl.nix`:

```nix

{
|

pkgs = prev.legacyPackages.${info.currentSystem};
|
||||
}
|
||||
```
|

In the old CLI, it was possible to supply a shorter `-E` flag instead of fully
|
||||
specifying `--expr` every time you wished to provide an expression that would
|
||||
be evaluated to produce the given command's input. This was retained for the
|
||||
`--file` flag when the new CLI utilities were written with `-f`, but `-E` was
|
||||
dropped.
|
||||
|
||||
We now restore the `-E` short form for better UX. This is most useful for
|
||||
`nix eval` but most any command that takes an Installable argument should benefit
|
||||
from it as well.

This man page describes the command `nix-build`, which is distinct from `nix

|
||||
|
||||
# Description
|
||||
|
||||
The `nix-build` command builds the derivations described by the Nix
|
||||
expressions in each *fileish*. If the build succeeds, it places a symlink to
|
||||
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 *fileish* is specified, then `nix-build` will use `default.nix` in
|
||||
If no *paths* are specified, then `nix-build` will use `default.nix` in
|
||||
the current directory, if it exists.
|
||||
|
||||
## Fileish Syntax
|
||||
|
||||
A given *fileish* may take one of a few different forms, the first being a simple filesystem path, e.g. `nix-build /tmp/some-file.nix`.
|
||||
Like the [import builtin](../language/builtins.md#builtins-import) specifying a directory is equivalent to specifying `default.nix` within that directory.
|
||||
It may also be a [search path](./env-common.md#env-NIX_PATH) (also known as a lookup path) like `<nixpkgs>`, which is convenient to use with `--attr`/`-A`:
|
||||
|
||||
```console
|
||||
$ nix-build '<nixpkgs>' -A firefox
|
||||
```
|
||||
|
||||
(Note the quotation marks around `<nixpkgs>`, which will be necessary in most Unix shells.)
|
||||
|
||||
If a *fileish* starts with `http://` or `https://`, it is interpreted as the URL of a tarball which will be fetched and unpacked.
|
||||
Lix will then `import` the unpacked directory, so these tarballs must include at least a single top-level directory with a file called `default.nix`
|
||||
For example, you could build from a specific version of Nixpkgs with something like:
|
||||
|
||||
```console
|
||||
$ nix-build "https://github.com/NixOS/nixpkgs/archive/refs/heads/release-23.11.tar.gz" -A firefox
|
||||
```
|
||||
|
||||
If a path starts with `flake:`, the rest of the argument is interpreted as a [flakeref](./new-cli/nix3-flake.md#flake-references) (see `nix flake --help` or `man nix3-flake`), which requires the "flakes" experimental feature to be enabled.
|
||||
Lix will fetch the flake, and then `import` its unpacked directory, so the flake must include a file called `default.nix`.
|
||||
For example, the flake analogues to the above `nix-build` commands are:
|
||||
|
||||
```console
|
||||
$ nix-build flake:nixpkgs -A firefox
|
||||
$ nix-build flake:github:NixOS/nixpkgs/release-23.11 -A firefox
|
||||
```
|
||||
|
||||
Finally, for legacy reasons, if a path starts with `channel:`, the rest of the argument is interpreted as the name of a *nixpkgs* channel tarball to fetch from `https://nixos.org/channels/$CHANNEL_NAME/nixexprs.tar.xz`.
|
||||
This is a **hard coded URL** pattern and is *not* related to the subscribed channels managed by the [nix-channel](./nix-channel.md) command.
|
||||
|
||||
> **Note**: any of the special syntaxes may always be disambiguated by prefixing the path.
|
||||
> For example: a file in the current directory literally called `<nixpkgs>` can be addressed as `./<nixpkgs>`, to escape the special interpretation.
|
||||
|
||||
In summary, a path argument may be one of:
|
||||
|
||||
{{#include ./fileish-summary.md}}
|
||||
|
||||
## Notes
|
||||
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`.
|
||||
