The “emacs-ess” package does not behave like all other Emacs packages. Its files are installed to “$out/share/emacs/site-lisp/ess” (not “guix.d”) and there are no autoloads.
I don’t know how to get ESS to work like this. Should the package be changed such that it installs autoload files like all other packages? -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
