eglot VS web-mode

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A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means.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

See https://github.com/joaotavora/eglot#diagnostics

(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.)

web-mode: https://web-mode.org/

Did you try web-mode? https://github.com/fxbois/web-mode/ It's the mode that made me accept HTML. There are shortcuts to: delete a node, wrap a node with another one, delete an attribute, copy a node, re-indent the buffer, go to the beginning/end of the node…

I’ve started to use emacs in my computer sciences school 30 years ago (EPITA in Paris). The Lab was surrounded by Mips, Sun, Alpha, … great time.

The only weakness of Emacs (according to me) was the lack of a good major mode (module) to edit web template : imagine editing a php block inside a javascript part embedded inside html.

After testing many modes, I started to develop web-mode (http://web-mode.org) that is now compatible with about thirty template engines. What a wondeful trip it was to discover the power of Lisp and what a pleasure it is everyday to know exactly what happens when I hit a key while editing an html file.

I am the only Emacs user in my company (kernix.com) but nothing would make me switch. I can not imagine using an editor that would not open in less than a second (or that would eat hundreds of Mo of RAM)

I Hope Emacs will see a usage surge with the inclusion of tree sitter… editing in emacs will be even faster and more robust. Not sure tree sitter is suitted for multi languages files … but for this you have web-mode ;)

web-mode should be used for .erb files, per their docs

Web Mode has support for razor pages. I used it briefly and it seems to be good. Here are the relevant parts of my config:

web-mode for editing templates

Been using web-mode recently and possess noticed that marked regions are unmarked once the cursor is moved. I use expand-region normally to mark HTML tags and then tried to move up one line and the marked region is cancelled. Using C-SPC to mark regions does not face this issue. Anyone face this issue and solve it? I know there was a similar issue with multiple cursors but ‏‏‎ that was solvable by editing a custom variable found here. Any suggestions are welcomed as I do not even know where to begin to debug this issue. Thanks!
