It is possible to specify nix.conf options on the command line with --<option name> <option value if necessary> (as opposed to --option <option name> <option value if necessary>). However, this does not appear to extend to aliases.
When running nix eval --expr '{}' --build-cores 0, the --build-cores flag is unrecognized. However, passing it as an --option allows it to work.
Steps To Reproduce
Install Nix 2.23.1
Run nix eval --expr '{}' --build-cores 0
See error that build-cores is not recognized (despite there being an alias to it from cores)
Try again with --cores 0 and see it succeed
This is reproducible for all settings with aliases.
Expected behavior
Aliases of nix.conf settings should work when passed as a flag, without needing to resort to --option <setting alias name> <value>
nix-env --version output
Reproduced on nix-env (Nix) 2.21.2, nix-env (Nix) 2.23.1, and nix-env (Nix) 2.24.0pre20240617_daf1b6b
