<I also posted this in emacs.help, then thought it might be better here.>
I'm an enthusiastic and error-prone new user of emacs (24.3.1) and org-babel (org 8.2.7c). I've been using lilypond mode in the context of org-mode documents, using the command "ly-tangle" to typeset music into midi and pdf files. It's been working great for the past few weeks, until today ... I updated some packages through the package manager, including org and org-plus-contrib, and now "M-x ly-" gives "[no match]" in the minibuffer. I didn't mess with my .emacs at all, which contains these lines: ;; ==== lilypond ==== (autoload 'LilyPond-mode "lilypond-mode") (org-babel-do-load-languages 'org-babel-load-languages '( (emacs-lisp . t) (sh t) (org t) (latex . t) (lilypond t))) (setq ly-arrange-mode t) (setq ly-nix-ly-path "lilypond") I'm wondering if I put something somewhere that got clobbered when the new versions installed in my .emacs.d/elpa folder. Or if the new version might have a bug. Thank you, if you have any help for me! -Steven
