From 727b43478cce8ebbd0f58530878d3af80a3ba233 Mon Sep 17 00:00:00 2001 From: Rebecca Turner Date: Thu, 4 Apr 2024 16:26:25 -0700 Subject: [PATCH] Add `repl-overlays` MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
