cider

EDIT Example, picked completely at random: https://github.com/clojure-emacs/cider/tree/master/dev (defun cider-tramp-prefix (&optional buffer) "Use the filename for BUFFER to determine a tramp prefix. Defaults to the current buffer. Return the tramp prefix, or nil if BUFFER is local." (let* ((buffer (or buffer (current-buffer))) (name (or (buffer-file-name buffer) (with-current-buffer buffer default-directory)))) (when (tramp-tramp-file-p name) (with-parsed-tramp-file-name name v (with-no-warnings (cider-make-tramp-prefix v-method v-user v-host v-port)))))) Here is a random function from CIDER. The code is simple enough, the lisp is no problem. Immediately we see we're interacting from one extension to another, have to understand Emacs buffers, need to know how warnings are displayed, have to understand parsing as a domain, and appear to have a network involved. That is a lot of work to debug one function when something is misbehaving. Not an unreasonable situation, but nonetheless a barrier. Then on top of that I have to go look up what let* is and why it is presumably different from let. One more thing I don't want to do. Emacs lisp sucks. EDITEDIT Tramp isn't an extension, it is part of core emacs. We live and learn. EDITEDITEDIT Spoke too quickly, it looks like it is a GNU-supported extension. This is the sort of trivia that got me using Doom Emacs.
