In which we talked about Hydra (0:11), Helm (0:22), packages (0:25), Quelpa/quse-package (0:29), EWW (0:30), Org Mode (0:40), global-flycheck-mode (0:51), widget, TRAMP (1:15), conferences/hangouts (1:26), more Hydra (1:28), Emacs Lisp (1:32), command-history (1:35), Emacs (1:38), plans for getting better (1:44), latexmk (1:49), and other things. (Times are approximate.)

Other questions/comments:

  • Not a question, but I just learned about command-history. Which is a great way to whip up a function. I’m amazed that I just discovered it. – Jonathan Hill
  • I saw something in 24.4 change log about a notification system. Could that maybe solve your problem? – Mitchell Hunter
  • On Air viewers cannot see Sasha due to Sridhar presenting. – Marc Tamsky
  • Anyone using tabs? – Levi Strope

The next Emacs Hangout will be on March 18, 2015, at 8 PM Toronto time (12 midnight GMT) https://plus.google.com/u/0/events/cbj3rg26d8j9ifaiff5uq00ncr4

Want to get notified about upcoming hangouts? You can sign up for notifications at http://eepurl.com/bbi-Ir . We’ll experiment with starting off with a mini-workshop/demo of Org tasks and agenda (or maybe Helm, if that’s more interesting).

Michael Hoffman 8:08 PM can someone repost that gmail/gnus link? that sounded awesome
Sridhar Ratnakumar 8:08 PM http://blog.binchen.org/posts/notes-on-using-gnus.html
Michael Hoffman 8:09 PM thanks Sridhar
Bob Erb 8:09 PM ace-jump-mode
Michael Hoffman 8:12 PM I find `guide-key-mode` very helpful for remembering keybindings as well
Sridhar Ratnakumar 8:13 PM https://github.com/abo-abo/hydra
Michael Hoffman 8:14 PM Sacha can you increase your font siz e? thanks
Michael Hoffman 8:19 PM that’s just an example this is my guide-key setup (require-package guide-key guide-key) (setq guide-key/guide-key-sequence ‘(“C-x” “C-c”)) (setq guide-key/recursive-key-sequence-flag t) (setq guide-key/idle-delay 0.7)
Sridhar Ratnakumar 8:20 PM pretty useful
Michael Hoffman 8:20 PM I don’t see any reason why not to set it up for everything C-x if you set it up with an idle-delay of 0.7 or something then it usually won’t bother you unless you can’t remember
JJ Asghar 8:23 PM ;; i need tab complete (define-key helm-map (kbd “<tab>”) ‘helm-execute-persistent-action)
Sridhar Ratnakumar 8:23 PM thx

Michael Hoffman 8:25 PM has anyone tried the eww web browser it’s definitely a curiosity more than a useful thing
Russell Black 8:25 PM I agree
Michael Hoffman 8:25 PM although i can see cases where it would be useful i keep my .emacs in version control

Default PACKAGE is FEATURE.” ;; for debugging (message “(require-package %s %s)” feature package) (let ((package (or package feature))) ; XXX: can I have a macro produce multiple forms instead of nesting like this? `(eval-and-compile (eval-when-compile (unless (or (require ‘,feature nil t) (fboundp ‘flycheck-byte-compile-dest-file)) ; don’t run within flycheck (package-install ‘,package))) (require ‘,feature nil t)))) WARNING: does not always work i gotta run guys, this has been great thanks so much sacha

Russell Black 8:32 PM I have to run to an appointment. Thanks guys!
