Hi Guix, AUCTeX breaks Emacs' bult-in url package. This bug appears to have been introduced with commit 3ffdd00 and can be reproduced as follows:
1) Install ‘emacs’ and ‘emacs-auctex’. 2) Start Emacs and do M-: (require 'url), which will produce the following backtrace: --8<---------------cut here---------------start------------->8--- Debugger entered--Lisp error: (void-function TeX-add-style-hook) (TeX-add-style-hook "url" #f(compiled-function () #<bytecode 0x48bbdd>) LaTeX-dialect) require(url) eval((require (quote url)) nil) eval-expression((require (quote url)) nil nil 127) funcall-interactively(eval-expression (require (quote url)) nil nil 127) call-interactively(eval-expression nil nil) command-execute(eval-expression) --8<---------------cut here---------------end--------------->8--- It looks like Emacs tries to load the file $GUIX_PROFILE/share/emacs/site-lisp/style/url.elc, which is provided by ‘emacs-auctex’, instead of $GUIX_PROFILE/share/emacs/26.3/lisp/url/url.elc, which is provided by Emacs itself.
