I have tried a couple auto-completions engines on emacs, I had been working with auto-complete because it was the only one that I got working. I simply added some modes to a list and it was done:

(add-to-list 'ac-modes 'asm-mode)
(add-to-list 'ac-modes 'go-mode)
(add-to-list 'ac-modes 'tex-mode)

However, it always felt janky, and I never really liked the style. Corfu on the other hands, works wonder but the problem is:

  • It only works with elisp; how can I make it work with other programming buffers

I tried using dabbrev with the config on the github page:

;; Use Dabbrev with Corfu!
(use-package dabbrev
  ;; Swap M-/ and C-M-/
  :bind (("M-/" . dabbrev-completion)
         ("C-M-/" . dabbrev-expand))
  ;; Other useful Dabbrev configurations.
  (dabbrev-ignored-buffer-regexps '("\\.\\(?:pdf\\|jpe?g\\|png\\)\\'")))

But it doesn't follow my TAB-GO config, and only "works" if I press C-M-/. However, it did auto-complete, so if I could add dabbrev's suggestions to Corfu, everything should work. I am a complete Emacs novice, so I may have done things wrong. I have googled everywhere, but to no avail.

  • Only one question per post, please.

To get more of corfu package, you need to add cape completion at point extension and configure it as shown on that page. The function needed for programming languages is cape-keyword (the others are also useful to be added).

As for asm-mode, you must provide some more info - there is a built-in package, asm-mode, but if you need/use Intel x_332/x_64, there is on Melpa a better package, masm-mode, which will clobber with asm-mode. Also if you need some cross-assembler, there are better tools/packages to use, just tell what you need.

Keep in mind there is also the lsp-mode package, which can also do completion. See this page.
