The exact locations depend on dlopen. Could you share the error message reported when loading a non-exist language? It should print all the locations it tries (as you observed). > > Yuan textmodes/mhtml-mode.el:29:2: Error: Cannot load language definition: "javascript", ("/home/jostein/.emacs.d/tree-sitter/libtree-sitter-javascript: cannot open shared object file: No such file or directory" "/home/jostein/.emacs.d/tree-sitter/libtree-sitter-javascript.so: cannot open shared object file: No such file or directory" "libtree-sitter-javascript: cannot open shared object file: No such file or directory" "libtree-sitter-javascript.so: cannot open shared object file: No such file or directory") Does that impliy it checks in the standard system library localtion? If so, I guess there's no problem. In that case, sorry for the "noise", but I just wanted to make sure this was packagable and thought one check too much is better than one check too little :) -- Vennlig hilsen *Jostein Kjønigsen* jostein@kjonigsen.net 🍵 jostein@gmail.com https://jostein.kjønigsen.no
