* Ivy/Counsel
|
||||
* Completion UI
|
||||
|
||||
[[http://oremacs.com/swiper/][Ivy]] is a completion system, giving you completions and fuzzy search whenever
|
||||
you interact with the minibuffer. I transitioned to Ivy from [[https://emacs-helm.github.io/helm/][Helm]], mainly due
|
||||
to it being aesthetically noisy, and that I didn't fully take advantage of
|
||||
all its features (which are numerous). Here are some customization's that
|
||||
made the transition a bit easier.
|
||||
I have transitioned from [[https://emacs-helm.github.io/helm/][Helm]] to [[http://oremacs.com/swiper/][Ivy]], and now, on to [[https://github.com/minad/vertico][Vertico]]. It improves the
|
||||
interface calling commands (i.e. ~M-x~), finding files, switching buffers,
|
||||
searching files and so on. Using the ~vertico-buffer-mode~ gives a more
|
||||
Helm-like experience, where completions are given a full fledged buffer.

** Completion
|

|
||||
I used [[https://github.com/auto-complete/auto-complete][Auto-Complete]] for years, then I used [[http://company-mode.github.io/][company-mode]] for even more years,
|
||||
and now I am giving [[https://github.com/minad/corfu][corfu]] a shot. I want a pretty aggressive completion
|
||||
system, hence the no delay settings and a short prefix length.

* Completion
|
||||
|
||||
[[https://github.com/auto-complete/auto-complete][Auto-Complete]] has been a part of my config for years, but I want to try out
|
||||
[[http://company-mode.github.io/][company-mode]]. If I code in an environment with good completion, I've made an
|
||||
habit of trying to /guess/ function-names, and looking at the completions for
|
||||
the right one. So I want a pretty aggressive completion system, hence the no
|
||||
delay settings and short prefix length.
