Add `repl-overlays` Adds a `repl-overlays` option, 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`: info: final: prev: let optionalAttrs = predicate: attrs: if predicate then attrs else {}; in optionalAttrs (prev ? legacyPackages && prev.legacyPackages ? ${info.currentSystem}) { pkgs = prev.legacyPackages.${info.currentSystem}; } We can run `nix repl` and use `pkgs` to refer to `legacyPackages.${currentSystem}`: $ nix repl --repl-overlays ~/.config/nix/repl.nix nixpkgs Lix 2.90.0 Type :? for help.
