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    A substantial section of the community is using corfu instead of company, but I wouldn't say company is out of date by any means.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

    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.

  • Eglot + clangd not working for NetHack code base
    3 projects | /r/emacs | 17 Jun 2023
    An update: I am now able to make everything work by generating `compile_commands.json` using compiledb. I'm aware that there is another tool Bear but for some reason it generates an empty `compile_commands.json` file for me.
  • New User C Setup Help?
    4 projects | /r/neovim | 24 May 2023
    Regarding the libraries, you might need to add it to clangd’s configuration. A convenient way is to have a compile_commands.json in your project (this is generated by some build tools like CMake, but if you don’t use them, have a look at bear).
  • vscode alternative for C++ on M1 mac?
    4 projects | /r/cpp | 15 May 2023
    Note that you need to have a compile_commands.json file. That file can easily be generated by CMake, Meson, etc. For other build systems checkout Bear https://github.com/rizsotto/Bear
  • I hope that cscope can make a comeback in the versions after 0.9
    2 projects | /r/neovim | 8 Apr 2023
    make a 'gcc' command/executable that do nothing and make it first in your PATH and then run bear with make: https://github.com/rizsotto/Bear/issues/219 It is unfortunate that bear doesn't catch the output of the make command with '--dry-run' as it still prints the compile commands, it seems not that hard to support this and I think many ppl would benefit..
  • Is CMake necessary to set up a C++ "IDE" in neovim?
    4 projects | /r/neovim | 17 Mar 2023
    But it sounds like maybe you’re assuming for the purposes of using something like clangd (highly recommended for coding in cpp projects in general, you want to be using this in vscode or whatever else anyway, codelion notwithstanding I suppose) with neovim on a c++ project that you have to use cmake to produce a compilation database to use with neovim plugins (e.g. clangd via nvim-lsp et. al.). In this case, be aware that the https://github.com/rizsotto/Bear tool is a handy way to just tack it on to whatever command you’re using to run a c++ code build step, and it will give you a compile_commands.json, corresponding to the compiler commands it invoked, on a silver platter.

    I guess your questionmarks are about installing "bear", he refers to this project: https://github.com/rizsotto/Bear
  • Mason LSP Not Detecting Header Files
    2 projects | /r/neovim | 4 Feb 2023
    You can use bear in order to generate compile_commands.json on compilation and make the errors disappear.
  • Clangd header files not found
    2 projects | /r/neovim | 4 Jan 2023
    I'd also recommend to use bear which helps clangd to find the header files and stuff if something doesn't work correctl.

    Have you tried it with bear to create the compile_commands.json file?
  • Help a Linux kernel dev setup LSP
    8 projects | /r/emacs | 18 Oct 2022
    Both servers need a compilation database compile_commands.json in order to populate and read symbols and locations, as well as flags and configurations. Some build generators like CMake and Meson are able to produce these files (cmake . -DCMAKE_EXPORT_COMPILE_COMMANDS=1 for the first and automatically for the latter). If you aren't using such a system and using, for example, plain Makefiles, you will need a tool like Build EAR to produce the compilation database.
