company-mode VS corfu

I'm curious to know what `company` does differently here than `corfu`. As a longtime user I couldn't be happier.

https://company-mode.github.io/

they wrote the first word and auto-completed the rest

For me, it's http://company-mode.github.io and maybe a touch of all-the-icons..

I'm not sure if I did anything special to enable it, but I'm pretty sure company-mode does this

When I started using Emacs I was following the setup outlined by System Crafters, which I still think is a really good introduction. But, over the last few months I've started to replace packages with more "minimalist" or "stripped down" packages. I've switched from Ivy and Counsel to Vertico and Consult, and recently I switched from company to corfu for auto-completion.

As for the Emacs configuration, you should only need a few lines of code, in order to get them up and running, if you are planning to keep your setup as close to vanilla as possible. If you are interested, you could additionally install a completion framework like company-mode to help you out.

As for auto-completion, there's a few different variants that people use. Auto-complete being one of them, but an alternative you might want to try is http://company-mode.github.io/

For the company-mode see Frontends.

Company is a classic, though corfu and cape, also by Daniel Mendler is really excellent.

You could try corfu. It has auto-completion disabled by default and works most places with M-Tab. Or you could set a longish corfu-auto-delay (0.75s say), and let auto popup only when you stop to ponder a while.

Corfu supports this. Or at least it allows you to move completions to the mini buffer which I find quiet useful.

A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means. In emacs 29 eglot will be a built in, which might act as a replacement for lsp-mode depending on what functionality you need.

Wow, interesting that my response is getting down voted. It seems not enough that I give away my work for free. Nevertheless I appreciate support from the community, as other Emacs package developers. The support is actually helpful. To clarify, publishing my configuration would translate into quite a bit of work, requiring separation of private and public bits.

I am currently using evil and corfu, but I want to configure such that pressing a single escape will invoke corfu-quit when its UI is active (because pressing "C-g" is harder).

A few days ago I found an unexplained slowness when using Corfu on Emacs 29 with pgtk. I stripped my configuration to basically just Corfu, and still had a noticeable delay. Maybe it is related to your problem. https://github.com/minad/corfu/issues/307

The most straight forward solution is probably the package company-math. (that's what I use but with corfu and cape)
