It depends. :-) Usually, something like guix thing stuff1 stuff2 is processed in that order: stuff2 then stuff1. Other said, the CLI is somehow parsed from right to left. For instance, see bug#43585 [1] or bug#50473. Well, compare: --8<---------------cut here---------------start------------->8--- $ guix package --show=emacs --show=zig | recsel -Cp name name: zig name: emacs $ guix package --show=zig --show=emacs | recsel -Cp name name: emacs name: zig --8<---------------cut here---------------end--------------->8--- (Note that “guix show” process from left to right since it is how most of us type and read.) That’s said, “guix build” is special. Because it somehow processes the topological order between stuff1 and stuff2. Other said, if stuff2 depends on stuff1, then it first builds stuff1 then second stuff2. 1: <http://issues.guix.gnu.org/issue/43585> 2: <http://issues.guix.gnu.org/issue/50473> Cheers, simon
