Snippets Auto Expansion on Emacs.app (macOS)

[kdmsnr]

Snippets Auto Expansion doesn't work on Emacs.app (macOS). Are there any workarounds?

 

• macOS Catalina 10.15.7
• Emacs 27.2

Hi @kdmsnr, welcome to the forum.

 

Have you tried adjusting Alfred’s Tweaking options? Try making the Restore After delay longer.

 

It looks like the problem is when Alfred tries to paste the snippet. How well does pasting into Emacs.app with ⌘V work?

Thank you for your reply. I've found the reason. It is because that Alfred doesn't care about the Emacs paste key is not ⌘V.

 

Dash cares about that and I assumed Alfred also would do so, but it doesn't. 😢

Does Dash use the clipboard to insert snippets?

[kdmsnr]

Yes, same as Alfred. But it use "^-y" instead of "⌘V" on Emacs.

If like me, you don't care about what emacs does with ⌘-v by default, you can add the following to your ~/.emacs

;; Make macOS paste work with ⌘-v
(global-set-key (kbd "M-v") 'clipboard-yank)

[kdmsnr]

Thank you, but I use the key as "cua-scroll-down" as default.

Then I think you’re probably out of luck wrt Alfred snippets in Emacs.app. @Andrew might consider special-casing Emacs.app, but I’d say the fault for the issue lies squarely with Emacs for not respecting basic macOS platform standards.

Well, you probably don't know much about Emacs. It's definitely Alfred's fault. As I mentioned earlier, the Dash support nicely.

Dude, it (or at least yours) doesn't support ⌘V on macOS. It's clearly Emacs that's not playing by the rules here…

Maybe Dash's developer is an Emacs user? Dunno. Point is, if an app doesn't support ⌘V for paste on macOS, I'd consider it a massive ask to expect any other apps' developers to work around that, and it would be going above and beyond if they did, imo.

 

You're totally right that I don't know much at all about Emacs (neovim all the way, baby!), but I do know you could get Alfred's snippet expansion to work yourself with a couple of lines of lisp…
