`nix-shell $x` now looks for `$x/shell.nix` when `$x` resolves to a directory.
|
|
|
|
Although this might be seen as a breaking change, its primarily interactive usage makes it a minor issue.
|
|
This adjustment addresses a commonly reported problem.
|
|
|
|
This also applies to `nix-shell` shebang scripts. Consider the following example:
|
|
|
|
```shell
|
|
#!/usr/bin/env nix-shell
|
|
#!nix-shell -i bash
|
|
```
|
|
|
|
This will now load `shell.nix` from the script's directory, if it exists; `default.nix` otherwise.
|
|
|
|
The old behavior can be opted into by setting the option [`nix-shell-always-looks-for-shell-nix`](@docroot@/command-ref/conf-file.md#conf-nix-shell-always-looks-for-shell-nix) to `false`.
