[Configuration settings](@docroot@/command-ref/conf-file.md) can now refer to
|
||
|
|
files with paths relative to the file they're written in or relative to your
|
||
|
|
home directory (with `~/`).
|
||
|
|
|
||
|
|
This makes settings like
|
||
|
|
[`repl-overlays`](@docroot@/command-ref/conf-file.md#conf-repl-overlays) and
|
||
|
|
[`secret-key-files`](@docroot@/command-ref/conf-file.md#conf-repl-overlays)
|
||
|
|
much easier to set, especially if you'd like to refer to files in an existing
|
||
|
|
dotfiles repo cloned into your home directory.
|
||
|
|
|
||
|
|
If you put `repl-overlays = repl.nix` in your `~/.config/nix/nix.conf`, it'll
|
||
|
|
load `~/.config/nix/repl.nix`. Similarly, you can set `repl-overlays =
|
||
|
|
~/.dotfiles/repl.nix` to load a file relative to your home directory.
|
||
|
|
|
||
|
|
Configuration files can also
|
||
|
|
[`include`](@docroot@/command-ref/conf-file.md#file-format) paths relative to
|
||
|
|
your home directory.
|
||
|
|
|
||
|
|
Only user configuration files (like `$XDG_CONFIG_HOME/nix/nix.conf` or the
|
||
|
|
files listed in `$NIX_USER_CONF_FILES`) can use tilde paths relative to your
|
||
|
|
home directory. Configuration listed in the `$NIX_CONFIG` environment variable
|
||
|
|
may not use relative paths.
