eglot VS vscode-intelephense

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A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means.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.)

I'm going to use intelephense to show the minimal configuration needed to setup a language server in Neovim.

This is the most important extension to install for PHP support. It provides a fast language server that adds code completion, go to definition, formatting, and more. You can also purchase a license at Intelephense, which I highly recommend. It adds some additional features like renaming symbols and other code actions.

You need to get the code, and use an IDE to help like vs code + PHP Intelephense (https://intelephense.com/)

I bought a license key to Intelephense https://intelephense.com/, and added the key as described in the documentation and several blog posts (at least I think I'm doing it right), however the paid features (e.g. rename symbol) don't work.

I'm quite happy with Emacs, coming from PhpStorm, using intelephense.com premium. I highly recommend.

Follow this guide to configure and add PHP Intelephense.

The error itself is the VSCode extension Intelephense, that is usually very helpful when writing PHP in VSCode, telling you that there is an error with an Undefined type ... after you have followed the steps outlined here in detail to install the permissions package on your Laravel app.

Furthermore, depending on which integrated development environment (IDE) you use, your editor detects the strict_types and warns you inside the editor before running your code. For example, I use the Intelephense extension inside Visual Studio Code, which warns me about wrong parameters before I run the code, like so:

Helix should use Intelephense by default, so if you install that, it should work out of the box. You can find installation instructions here 🙂

Look at either Intelephense or Devsense as plugins and you'll get a close to IDE level experience.
