Bas van Dijk cee35739ff mkshell: improve mergeInputs ... mergeInputs is now simply defined in terms of `concatLists` and `catAttrs` instead of a more complicated `foldr`. Note that the order of PATH has also changed. For example running the following with nix-shell: let pkgs = import <nixpkgs> {}; shell1 = pkgs.mkShell { buildInputs = [ pkgs.htop ]; }; shell2 = pkgs.mkShell { buildInputs = [ pkgs.hello ]; }; shell3 = pkgs.mkShell { inputsFrom = [ shell1 shell2 ]; buildInputs = [ pkgs.tree ]; }; in shell3 Results in the following PATH: $ echo $PATH ... /nix/store/yifq4bikf7m07160bpia7z48ciqddbfi-tree-1.8.0/bin: /nix/store/vhxqk81234ivqw1a7j200a1c69k8mywi-htop-2.2.0/bin: /nix/store/n9vm3m58y1n3rg3mlll17wanc9hln58k-hello-2.10/bin ... Previously the order was: /nix/store/n9vm3m58y1n3rg3mlll17wanc9hln58k-hello-2.10/bin /nix/store/vhxqk81234ivqw1a7j200a1c69k8mywi-htop-2.2.0/bin: /nix/store/yifq4bikf7m07160bpia7z48ciqddbfi-tree-1.8.0/bin: I think the new order makes more sense because it allows to override the PATH in the outermost mkShell.		2019-06-23 22:20:10 +02:00
