jdee VS vertico

I think Emacs is great for programming. It has modes for almost every programming language. For LaTeX mode the AUCTeX package is incredibly useful. Besides LaTeX the languages I most often write code in are bash, Java, Tcl, troff, Octave, R, Clojure, Objective-C, and Scheme. Emacs has good modes for all those (in particular JDEE is what I use for Java). There are auto-completion packages for Emacs, though typically I use those only for the few times I write C or C++. Emacs also integrates well with most version control software.

I'm still using jdee. Because of the updates to how JDK after Java 8 locates core classes, I had to make an update to the jdee server backend that is used for things like finding import class names. Once I did that I'm able to use it with Java 8 on up. I believe that the github repo fo the server now has the same updates.

It would be great if you add your snippet to the Vertico wiki. Such tweaks can be quite instructive for others who want to achieve the same or similar effects for other completion commands.

If you want completion to be sorted by your "most recent" I suggest you have a look at completion libraries. One example is vertico; when you enable savehist mode, the variable magit-revision-history, containing the branches you visited is persisted between sessions and vertico use that offer completions by most-recently-used, by default.

I think vertico is best alternative recently, really fast on Linux, macOS and Windows.

(use-package modus-themes :vc (:url "https://gitlab.com/protesilaos/modus-themes" :branch "main")) (use-package vertico :vc (:url "https://github.com/minad/vertico" :rev :newest :lisp-dir "extensions/"))

An example relevant to your list would be some changes many people are taking with their completion framework - using package that leverage core emacs functionality rather than replacing it with a complete package that 'overrides' it. Consult, vertico, orderless and associate packages come to mind here. If you do a bit of a search you'll find plenty of info. Here is a video from Prot on the subject, but there are many others as well. I think Prot actually went on to write his own completion system to overlay native emacs functionality as well.

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).

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 thought that lsp and rtags were different tools to do different things. Regarding lsp, I configured lsp-mode in my init file indeed! Currently I'm using Vertico (plus recommended sub-packages at github repository) and lsp-mode.

Hey! There has already been a horizontico.el. ;)

FYI, selectrum is getting deprecated in favor of vertico. https://github.com/minad/vertico/issues/237
