Yep, make sense to me. I also find cases from time to time, when some binary or another isn't found by some elisp code. However, providing those binaries via PATH can make some code or programs to work, when executed from inside Emacs and not to work in the environment outside, which can be really confusing in some cases. A simple example, imaging we have a script: 1.sh, which contains: sh --version This one will work: guix shell emacs-with-bash --pure -- emacs --eval '(shell-command "./1.sh")' This one will not: guix shell emacs-with-bash --pure -- ./1.sh That said, the idea of patching all the pathes to binaries seems better to me. -- Best regards, Andrew Tropin
