company-mode VS helm

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.

Oh wow wow wow! I just checked your commit on the repository. That's so amazing. I really appreciate that. And I also found a convenient donation link.

Next you "only" have to remember (elisp) function names. "Completion UIs" like ivy/counsel, icomplete, helm or vertico/consult, give you a nice auto completion list on M-x (choose the one of them, you like the most). Some of those Completion UIs will display existing keybindings and a short documentation for commands, near the auto complete candidates. So you will start to remember more keybindings without "learning sessions", just because invoking functions via keybindings is much faster (more convenient).

I use imenu, and helm-imenu to filter out the list interactively. Instead of scrolling through, you "jump" to an item via completion like helm-imenu, which filters all headings interactively in real-time as you type.

I personally use Helm, so I can manage all files (open, delete, copy, rename, etc) all from completing prompt directly, I don't need to open Dired for that.

Helm 1.2 release was in September 2011: https://github.com/emacs-helm/helm/releases/tag/v1.2

I updated helm recently and when trying to use it after startup I was hitting "Defining as dynamic an already lexical var" . debugger showed me it was due to `ffap-machine-p-local` not being defined yet, digging into helm-lib.el i found that it is due to the ffap let bindings added recently to `helm-guess-filename-at-point` - the first one was to address this issue https://github.com/emacs-helm/helm/issues/2574 and more recently two more ffaps were let bound. I can fix by adding `(require 'ffap)` in the helm `use-package` `:config` -- wondering if this is the recommended way or if it might be something worth living inside helm-lib.el near the top where it requires cl-lib already?

Yes, Helm. Probably others like Embark.
