crafted-emacs VS eglot

Keep an eye on Crafted Emacs which has a v2Beta release branch. It's been evolving. The v2Beta is a rewrite. It aims to provide a minimalist leg up on vanilla Emacs for new Emacs users. It's goal is to take you from first steps to a point where you have learned a great deal and built your configuration. Then you may be comfortable ditching the Crafted Emacs boilerplate configuration entirely. Think of it as a starter kit. Follow SystemCrafters on YouTube (live stream mostly) & Matrix (they are leaving Discord). Despite the live stream being lengthy, there is much to be learned as you bear witness to David figuring things out. Over time, you pickup on those techniques such as looking up a variable state, reviewing functions, evaluating snippets of Elisp in real time, etc. Also recommend, Mastering Emacs as a fantastic ebook with free updates. Once 29.1 ships, no doubt, there will be a free update to the ebook.

I'd recommend you have a look at crafted-emacs. It's an example of how far Emacs can actually go without third-party packages. Then you can add minimal packages (completion and specific tool integrations) to further enhance the experience.

For me it's quite stable except some issues I had with vertico. Anyways, I first started to rewrite my doom config into plain vanilla emacs (with org mode literate configs), and then I discovered crafted which allowed me to remove some code with commonly set sane defaults, e.g. stuff from https://github.com/SystemCrafters/crafted-emacs/blob/master/modules/crafted-defaults.el.

I have been surprised at how many people have so ardently defended only using built-ins and raw package.el and their own janky ensure methods when use-package was available and did it all better. And, it even lets you configure Emacs itself (not just packages), as well as seamlessly letting you try different package management tools like straight.el. Getting it into Emacs itself hopefully makes this a more prevalent way of showing users how to craft their own config.

If you need a staring point for configuring there's some nice light ones like emacs-bedrock and crafted-emacs, and also some fully pre-configured Emacs distributions that you can choose from (though those look harder to configure to one's personal needs to me, but I haven't tried them so wouldn't know).

Recently I stumbled upon this issue:

https://github.com/joaotavora/eglot/discussions/1127

I don't know enough about emacs and LSP to see the full picture, but it seems that both eglot's and corfu's maintainers, assumably very competent programmers, can't find a solution for this.

I only skimmed the thread. My understanding is that LSP dumps a long list of completion candidates at once and they can't decide a cache strategy that works well with existing code...?

It could be. There are unfixed issues with eglot and corfu, and sadly not a lot of willingness to investigate.

Eglot errors when I add new Python code blocks. The error disappears when I reconnect the language server, but the same happens again when I add a new code block. My "workaround" now is that before I start working on the .qmd file, I just add a bunch of Python code blocks (for which I also have a function) and then reconnect the language server again. This way I can start working for a while until I need to add more code blocks again.

This discussion has helped with some performance issues: https://github.com/joaotavora/eglot/discussions/993.

I guess eglot doesn't support it yet: https://github.com/joaotavora/eglot/pull/839

This is not by pure chance, João is the developer of the Eglot LSP client and the breadcrumbs from LSP-mode had been requested as a feature, but as far as I remember João thought rightfully that this could be an independent package, see https://github.com/joaotavora/eglot/discussions/988

A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means. In emacs 29 eglot will be a built in, which might act as a replacement for lsp-mode depending on what functionality you need.

I am currently running emacs 29 (built from emacs-29 branch) which – according to https://github.com/joaotavora/eglot – should contain the latest eglot.

Yep. You can use flymake or flycheck for that in combination with eglot or lsp-mode.

(I have reported this (that is, ElDoc missing docs for callable things at point, when Eglot is enabled) as an issue recently: First on GitHub-discussions https://github.com/joaotavora/eglot/discussions/1200, then on Debbugs https://debbugs.gnu.org/cgi/bugreport.cgi?bug=62687. But the threads are very long, so I don't recommend reading them.)
