Check out the Emacs Conferences and Hangouts page on Google+ to find out about upcoming hangouts, or sign up for the mailing list. Feel free to e-mail me at [email protected] to suggest a time for an Emacs Hangout. Looking forward to seeing you!

If there is a scheduled or ongoing Emacs Hangout, you can watch it at (no login needed) or join it at (Google account required).

Emacs hangout notes

Prompted by Michael Fogleman’s tweet that he’d like to see a bunch of us Emacs geeks get together in one room for a hackathon, Nic Ferrier and I tried out a casual Emacs hangout. Tinychat didn’t work, but Google Hangouts worked fine. A bunch of people saw our tweets about it too and dropped by, yay! Here are some things we talked about (mostly nifty tweaks from Nic):

  • shadchen is great for pattern matching, especially within trees
  • Alec wanted to know about Emacs and Git, so Nic demonstrated basic Magit
  • after-init-hook – load things there instead of in your ~/.emacs.d/init.el, so that your init.el does not break and you can test things easily from within Emacs
  • I shared isearch-describe-bindings, which had a number of goodies that I hadn’t known about before
  • Recognizing the opportunity to share what you’re working on (ex: nicferrier’s working on an Emacs Lisp to Javascript compiler)

Google Hangouts screensharing worked well for us, giving multiple people the opportunity to share their screen and allowing people to choose what they wanted to focus on. Nic also started up a tmux session and a repository of public keys, but that’s a bit more involved and requires more trust/coordination, so screen-sharing will likely be the way to go unless people have more of a pairing thing set up. This kind of informal hangout might be a good way for people to share what they’re working on just in case other people want to drop by and help out or ask questions (which people can optionally answer, or postpone if they want to stay focused on their work). Something a little more focused than this might be to pick one bug or task and work on it together, maybe starting with a “ridealong” (one person screenshares, thinking out loud as he or she works, and taking the occasional question) and moving towards full pairing (people working on things together). Some of my short-term Emacs goals are:

  • Improve my web development workflow and environment (including getting the hang of Magit, Smart Parens, Skewer, AutoComplete / Company Mode, and other good things)
  • Learn how to write proper tests for Emacs-related things
  • Get back into contributing to the Emacs community, perhaps starting to work on code/tests
  • Look up my Org agenda on my phone, probably with Org Mobile or some kind of batch process

Let’s give this a try. =) I set up a public calendar and added an event on Nov 5, 9-11PM Toronto time. If folks want to drop by, we’ll see how that works out!

Experimental Emacs Hangout 2014-11-05

Event page has some comments:

YouTube page:


Apologies for the recording weirdness – I was experimenting with the feature that lets you occasionally focus the video feed on a specific person instead of letting it switch based on volume, and sometimes I forgot that I had that on while other people were talking. Also, I was having screensharing weirdness. And I was writing down notes on a Post-It somewhere in order to minimize typing noises, but I seem to have made the note vanish (yay nerves). But hey, zeroth episode, and we’ll keep on making it better! =) If you want to add notes/highlights in the comments for this blog post, that would be awesome.

Next one Nov 19 Wed 1-3 PM EST – I’ll redirect to it, so you should be able to find it there at that time. =)

Recording from Emacs Hangout #2

Thanks to Cameron Desautels for hosting this one! =D I totally like Emacs Hangouts. We should have more of them.

  • tips for showing people how awesome magit is: partial staging, history browsing, diff viewing and jumping to the source file
  • org-present, org-babel, org inline images, source code highlighting
  • themes
  • magit new version, dealing with problems, history browsing, subcommands (:), remoting (M), interactive rebase (E), new features, Wazzup – shows you branch differences (w)
  • magit workflows, customization (ex: full-screen), fun with bisecting
  • use-package, delaying configuration
  • Dvorak, keyboard customization
  • evil-mode
  • selective display – folds everything beyond an indentation depth
  • managing large screens – folding, follow mode, etc.
  • projectile-mode
  • flx ido
  • ace-jump-mode – binding to C-0
  • Emacs on Mac OS X, terminal Emacs, sharing clipboard (pbcopy)
  • binding things to C-number; M-number, prefix arguments

Emacs Hangout #3: Emacs can read your mind

We’ve been organizing these Emacs Hangouts as an informal way for folks to get together and swap tips/notes/questions. You can find the previous Hangouts at . In this hangout, we shared tips on Emacs configuration, literate programming, remote access, autocompletion, and web development. And then Jonathan Arkell blew our minds with, well, his mind, demonstrating how he got Mindwave working with Emacs and Org Mode. The next one is scheduled for Jan 9, 2015 (Friday) at 7 PM Toronto time (12 AM GMT) – . Want a different time? Feel free to set up an Emacs Hangout, or contact me ([email protected]) and we’ll coordinate something.

me 8:45 PM Christopher: Gmail client might be nice. I use IMAP occasionally, but I miss the priority inbox.
Christopher Done 8:46 PM yeah. i used offlineimap for a while with notmuch.el, that was pretty good. but i’m tempted by the idea of a “light-weight” approach replacing the browser with emacs, requesting emails/search on demand. might be nice their API looked super trivial to work with
Jonathan Arkell 8:48 PM Sorry Yea Is qwelpa (sp?) native emacs? (elisp) Stupid mic. works great for music.
Jacob MacDonald 8:50 PM lol
Jonathan Arkell 8:50 PM I do all my configuration and packages in Org mode

Jonathan Arkell 8:51 PM Ironically not. I am Launching my DAW now to try and sort it ot.. heh err out … not ot…
jay abber 8:53 PM M=x list-packages now installing org-mode
me 8:53 PM Jay: If you’re installing Org from package, be sure to do it in an Emacs that has not loaded an Org file. because Org 8 (package) and Org 7 (which is built into Emacs) have incompatibilities

2015-01-09 Emacs Hangout

WELL. That was odd. Somehow the Google universe bifurcated and I spent the first forty minutes awkwardly talking to myself (braindumping Emacs tips) while the rest of the people in the Emacs hangout (1) wondered about my non-existence, and (2) got on with a great conversation about Emacs. I even did the “Hey, can folks hear me?” sort of thing and since some people were in the text chat and confirmed there were technical issues, I assumed that (a) we were talking about the same technical issues, and (b) many of them were inaudible because of said technical issues (or because they were at work, or whatever). The test audio played fine on my end, and the microphone sound levels looked fine too. I could see the group chat and everything. When it finally occurred to me to refresh my screen (which I had hesitated to do because that might end the session for everyone), I finally joined.

BIG THANK YOU to all the Emacs geeks who shrugged at my absence and carried on chatting. =)

Anyway. Fortunately, the recording is actually from their side of the parallel universe, and my interminable, horribly embarrassing blathering is lost forever. (I hope.) I mistakenly clipped it before, but it should be back to normal now.

Here it is.

Let’s get Emacs Hangouts sorted out for February and March. I think I can avoid technical debacles like this if I schedule something where I know at least one other person will turn up a little early and help me with a tech check. If you volunteer, we can pick a time that matches you. (Yay!) Leave a comment or e-mail me at [email protected] . =)

Also, since mailing lists can be useful, here’s one for Emacs Hangout announcements. You’ll get an e-mail to the Google+ Event when we figure out date/time, and another reminder the day before the event. Sign up at

Experimental Emacs Hangout 2015-02-18

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)

Want to get notified about upcoming hangouts? You can sign up for notifications at . 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 8:12 PM I find `guide-key-mode` very helpful for remembering keybindings as well
Sridhar Ratnakumar 8:13 PM
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
JJ Asghar 8:23 PM
Sridhar Ratnakumar 8:23 PM (we are talking about )
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

Sridhar Ratnakumar 8:32 PM eww renders images fine; but the layout is not correct
Russell Black 8:32 PM I have to run to an appointment. Thanks guys!
Howard Abrams 8:33 PM Never renders perfectly,. but if you are selective in what you are browsing, it is useful for things like programming documentation that fails to supply a info version.
[email protected] 8:33 PM jittery audio. reconnecting..
[email protected] 8:34 PM i can’t hear anyone
Sod Oscarfono 8:39 PM how about time tracking sacha?

Jacob MacDonald 8:53 PM I build Emacs from Git, so that’s … fun Look at the use-package source .
Bob Erb 8:57 PM (when (memq window-system ‘(mac ns)) (exec-path-from-shell-initialize))
Sod Oscarfono 8:57 PM i just stick to nix based systems so that saves me any hassle there
Sod Oscarfono 9:04 PM you seasoned professionals maybe already know this but i recently discovered the ability to export org to open office docs and pdfs from org: C-c C-e o for open office C-c C-e p for pdf.
Jason Lewis 9:05 PM @sridhar, magit is really nice for using git from emacs
Sridhar Ratnakumar 9:06 PM is generated from C-c C-e h h
Sod Oscarfono 9:10 PM hahaha… there’s an app for that -itis!
Bob Erb 9:11 PM there’s a mode for that

Sridhar Ratnakumar 9:18 PM Howard – what font do you use in Emacs, per the screenshot in ?
Jason Lewis 9:19 PM
Sod Oscarfono 9:25 PM workflow/project and time management/ literate programming. maybe a session where we scrutinize/optimise init files ? we spoke a bit about it already but its always good
Sod Oscarfono 9:30 PM i concur.. thanks sacha
Sod Oscarfono 9:32 PM cut and paste ninja over here.. hahaha
Jason Lewis 9:33 PM I’ve still not managed to make the jump to writing much lisp hope to one day

Sod Oscarfono 9:46 PM i’m currently experimenting with desktop publishing from emacs
Zachary Kanfer 9:48 PM my init file:
Sod Oscarfono 9:48 PM org-mode to pdf to bypass creative cloud / scribus.. but learning latex also. ah thats what i needed to hear cheers jason for sure.. i’m glad i stopped by maybe we also look at where is emacs deficient? can we collaborate on a tool, a bug or whatever. good idea. or we spit out our command history for ideas
