As of Emacs 24.3, an analog of the old multi: syntax has been layered on top of the modern tramp-default-proxies-alist approach, meaning that you can once again perform multi-hops without any prior configuration. For details, see: C-hig (tramp)Ad-hoc multi-hops RET With the new syntax, each ‘hop’ is separated by |. The example in the manual … Read more
Update: Emacs 24.3 has been released with full support for this new setting! In the current trunk of emacs, you can simply customize the variable create-lockfiles: C-h v create-lockfiles Documentation: Non-nil means use lockfiles to avoid editing collisions. In your init file, you can set (setq create-lockfiles nil) Get it via bzr branch bzr://bzr.savannah.gnu.org/emacs/trunk emacs-trunk … Read more
If you’ve ever been saved by an Emacs backup file, you probably want more of them, not less of them. It is annoying that they go in the same directory as the file you’re editing, but that is easy to change. You can make all backup files go into a directory by putting something like … Read more
In short, most terminal emulators are limited in the control characters they can produce (for the simple reason that the original terminals that they are emulating were likewise limited). So your terminal is very likely not producing anything other than . when you press C-. (and if that’s the case, that’s basically your answer, unless … Read more
The Bad test-a is self-modifying code. This is extremely dangerous. While the variable x disappears at the end of the let form, its initial value persists in the function object, and that is the value you are modifying. Remember that in Lisp a function is a first class object, which can be passed around (just … Read more
It’s worth noting why Emacs defers the package initialization: See C-hig (emacs) Package Installation RET, and in particular: The reason automatic package loading occurs after loading the init file is that user options only receive their customized values after loading the init file, including user options which affect the packaging system. In some circumstances, you … Read more
I use a minor mode for all my “override” key bindings: (defvar my-keys-minor-mode-map (let ((map (make-sparse-keymap))) (define-key map (kbd “C-i”) ‘some-function) map) “my-keys-minor-mode keymap.”) (define-minor-mode my-keys-minor-mode “A minor mode so that my key settings override annoying major modes.” :init-value t :lighter ” my-keys”) (my-keys-minor-mode 1) This has the added benefit of being able to turn … Read more
