That sounds great, just like I would have hoped that it'd work. And, because of this: "or the file in there changes", in a way it's even safer than a Makefile — in that Make wouldn't notify me if the Makefile got changed, but Direnv does (and people might not remember to look at any Makefile diff after pulling from the repo). — Now I'm starting slightly thinking about if Direnv makes sense somewhere in my own project(s).
