Hi, I compile all my files with Emacs and standalone context. I would like to compare context lmtx. I added this in my .emacs file but it does not work. ############################################################################# (eval-after-load "context" '(setq TeX-command-list (cons '("ConTeXt" "PATH=/home/viserion/context/tex/texmf-linux-64/bin:$PATH context --purgeall %s" TeX-run-command nil t :help "Run context (MarkIV)") TeX-command-list) ("ConTeXt" "PATH=/home/viserion/data/context/tex/texmf-linux-64/bin:$PATH context --purgeall %s" TeX-run-command t t :help "Run context (LMTX)") t) ) ############################################################################# For information about GNU Emacs and the GNU system, type C-h C-a. File mode specification error: (wrong-type-argument symbolp (ConTeXt PATH=/home/viserion/data/context/tex/texmf-linux-64/bin:$PATH context --purgeall %s TeX-run-command t t :help Run context (LMTX))) Thank you.
