Some time ago someone posted a cool hack to use Emacs as the shell for Make, and today I had a related thought: Could I run my Makefile with guix shell --manifest=manifest.scm so that I always run with the correct dependencies installed?

Yes I can.

SHELL = guix
.SHELLFLAGS = shell --manifest=manifest.scm -- sh -c

first:
node --eval='console.log("hello!");'

With a manifest file:

(packages->manifest
(list (specification->package "node")))

Now I don't have to remember to load a guix shell before running my make commands 😊 I also added it to my Literate Build Files page on my site.

I'm guessing this is GNU Make specific, though, not portable.
