  • LSP could have been better
    12 projects | news.ycombinator.com | 11 Oct 2023
    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...?

  • Using Quarto with Emacs
    2 projects | /r/emacs | 9 Jun 2023
    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.

  • joaotavora/breadcrumb: Emacs headerline indication of where you are in a large project
    4 projects | /r/emacs | 12 May 2023
    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
  • Returning emacs user - what packages are common now?
    9 projects | /r/emacs | 9 May 2023
    A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means.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.

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

  • Problems with eglot - configuration?
    2 projects | /r/emacs | 11 Mar 2023
    C-h R eglot RET fails to find anything - presumably it's the same Troubleshooting as at https://github.com/joaotavora/eglot (but that's not very helpful).
    2 projects | /r/emacs | 11 Mar 2023
    Honestly - I've had a fair crack at searching and reading on the topic, I'm not just sitting around whinging. Nothing about it at https://github.com/joaotavora/eglot nor when doing C-h f eglot-... so I'm thinking it's all a bit too hard for me.
  • Would you pay for an Emacs distro?
    2 projects | /r/emacs | 5 Mar 2023
    1) xref does not work properly with eglot in ESS. I want it to be able to work normally, and be able to find definitions in files that have not been loaded but are in the project directory. I think it's related to this
  • Emacs bankruptcy
    17 projects | /r/emacs | 3 Mar 2023
    Smart completion these days is done primarily through LSP. eglot is fairly minimal but built-in as of 29, also available via GNU Elpa. lsp-mode is another option with more integrations and a bit more fleshed out.

  • Mun v0.4.0 released
    4 projects | /r/rust_gamedev | 13 Dec 2022
    For those of you who haven’t heard of Mun before, Mun is an embeddable programming language empowering creation through iteration. The idea to create Mun originated out of frustration with the Lua dynamic scripting language and a desire to have similar hot reloading functionality available in Rust. As such, it’s not a direct competitor with Rust, but instead is intended to be used with Rust (or C/C++) as a host/embedded language pairing. Actually, Mun is completely written in Rust, building on similar crates as rust-analyzer and rustc. Its key features include:
