# Release 2.15 (2023-04-11)
|
|
|
|
* Commands which take installables on the command line can now read them from the standard input if
|
|
passed the `--stdin` flag. This is primarily useful when you have a large amount of paths which
|
|
exceed the OS argument limit.
|
|
|
|
* The `nix-hash` command now supports Base64 and SRI. Use the flags `--base64`
|
|
or `--sri` to specify the format of output hash as Base64 or SRI, and `--to-base64`
|
|
or `--to-sri` to convert a hash to Base64 or SRI format, respectively.
|
|
|
|
As the choice of hash formats is no longer binary, the `--base16` flag is also added
|
|
to explicitly specify the Base16 format, which is still the default.
|
|
|
|
* The special handling of an [installable](../command-ref/new-cli/nix.md#installables) with `.drv` suffix being interpreted as all of the given [store derivation](@docroot@/glossary.md#gloss-store-derivation)'s output paths is removed, and instead taken as the literal store path that it represents.
|
|
|
|
The new `^` syntax for store paths introduced in Nix 2.13 allows explicitly referencing output paths of a derivation.
|
|
Using this is better and more clear than relying on the now-removed `.drv` special handling.
|
|
|
|
For example,
|
|
```shell-session
|
|
$ nix path-info /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv
|
|
```
|
|
|
|
now gives info about the derivation itself, while
|
|
|
|
```shell-session
|
|
$ nix path-info /nix/store/gzaflydcr6sb3567hap9q6srzx8ggdgg-glibc-2.33-78.drv^*
|
|
```
|
|
provides information about each of its outputs.
|
|
|
|
* The experimental command `nix describe-stores` has been removed.
|
|
|
|
* Nix stores and their settings are now documented in [`nix help-stores`](@docroot@/command-ref/new-cli/nix3-help-stores.md).
|
|
|
|
* Documentation for operations of `nix-store` and `nix-env` are now available on separate pages of the manual.
|
|
They include all common options that can be specified and common environment variables that affect these commands.
|
|
|
|
These pages can be viewed offline with `man` using
|
|
|
|
* `man nix-store-<operation>` and `man nix-env-<operation>`
|
|
* `nix-store --help --<operation>` and `nix-env --help --<operation>`.
|
|
|
|
* Nix when used as a client now checks whether the store (the server) trusts the client.
|
|
(The store always had to check whether it trusts the client, but now the client is informed of the store's decision.)
|
|
This is useful for scripting interactions with (non-legacy-ssh) remote Nix stores.
|
|
|
|
`nix store ping` and `nix doctor` now display this information.
|
|
|
|
* The new command `nix derivation add` allows adding derivations to the store without involving the Nix language.
|
|
It exists to round out our collection of basic utility/plumbing commands, and allow for a low barrier-to-entry way of experimenting with alternative front-ends to the Nix Store.
|
|
It uses the same JSON layout as `nix derivation show`, and is its inverse.
|
|
|
|
* `nix show-derivation` has been renamed to `nix derivation show`.
|
|
This matches `nix derivation add`, and avoids bloating the top-level namespace.
|
|
The old name is still kept as an alias for compatibility, however.
|
|
|
|
* The `nix derivation {add,show}` JSON format now includes the derivation name as a top-level field.
|
|
This is useful in general, but especially necessary for the `add` direction, as otherwise we would need to pass in the name out of band for certain cases.
