modus-themes VS company-mode

I recall a video by Prot where he addressed this very thing in his modis vivendi & modis operendi themes, specifically where he toggles between the two. See https://github.com/protesilaos/modus-themes/blob/main/modus-themes.el, specifically function "modus-themes-after-load-theme-hook". Function "make-obsolete-variable" is used there to undefine all the attributes defined in the theme. HTH

Did You tried Modus themes by Prot?

The Modus Operandi theme doesn't appear to use much green in org mode and is highly configurable. Depending on what version of emacs you're on, it may already be included in emacs, or you can get it here: https://github.com/protesilaos/modus-themes

One thing made by Prot that has made a big difference to me is his high-contrast light theme Modus Operandi, which has made working on Emacs outside in bright sunlight a cinch. It's comprehensive in terms of the modes it supports, and he chose colours based on WCAG AAA standards. Highly recommended.

Here's a link to where you can see screenshots of his themes:

The code is stored at https://github.com/protesilaos/modus-themes for example:

Gitlab repo of the themes OR its mirror on Github.

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.
