    Doing a fast scan on the commit history this is probably related to https://github.com/hrsh7th/nvim-cmp/pull/1689 . Hope it helps.
  • Do I need NeoVIM?
    11 projects | /r/neovim | 7 Dec 2023
    https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

  • is it possible to limit the size of nvim-cmps autocompletion window?
    1 project | /r/neovim | 18 Jul 2023
    one thing that always annoyed me is how the autocomplete window behaves. when the space below your current line isn't sufficient it just teleports above the line. i know you can set a custom menu direction but i'd much rather have it pop up in a consistent place that is below the current line. the other behavior i dislike is the sizing. it's as big as the longest function in the list which can make the window enormous, to the point where there's almost no place left for the docs window. there aren't really any docs in the example below but i imagine with the little space that is left it'll get troublesome for more verbose docs such as with rust. i'd like to somehow tell nvim-cmp to always pop up below the current line, no matter how long the list is and possibly limit the horizontal size. is that at all possible? i've looked through the nvim-cmp wiki but haven't found an adequate solution. does this go beyond nvim-cmp?
  • Toggling the nvim-cmp documentation window
    1 project | /r/neovim | 4 Jul 2023
    Update: This isn't currently supported by nvim-cmp (and in fact it has been a feature request for a bit) and so I did my best and opened a PR that implements it :)

  • I can't stand using VSCode so I wrote my own (it wasn't easy)
    10 projects | news.ycombinator.com | 21 Apr 2024
    As well as its own plugins Vim/NeoVim can use VSCode's LSPs, DAPs and extensions either directly or via plugins like CoC[1] and Mason[2].

    I would be surprised if emacs couldn't do the same.

    It is flatly the wrong mindset to think of vim as an IDE. vim is a code editor: get in, make change, get out. Consider vim koans, which are a fun little read. You can throw coc.nvim at Neovim, along with a few other bits to give you a Good Enough setup, but vim isn't and will never be an IDE.
  • Using CoC inlay hints
    1 project | /r/vim | 11 Nov 2023
    I just did a fresh reinstall of CoC, on a newer version of Neovim. I'm now seeing something I hadn't seen before, which CoC calls "inlay hints". They look like this:

    I'm currently on an old setup (using coc and polyglot) and nvim v0.6.1. I'll be updating to a more modern setup within next year, using the native lsp and building nvim more frequently. But that's not today.

    There are some plugins which have the best documentations I have ever seen, but you need to read it from the Vim.

    Actually you can with coc.nvim & coc-sh. So long as shellcheck is also installed and in PATH, it'll integrate with coc/vim just fine.
  • how to set up coc.nvim extension on offline machine?
    2 projects | /r/vim | 7 Jun 2023
    When you install an extension it runs an npm install or yarn, iirc, which is going to be problematic for you being offline. I was going to say you could copy that ~/.config/coc folder directly to the other machine but yeah, Windows, no idea. You see here https://github.com/neoclide/coc.nvim/wiki/Using-coc-extensions
  • GCC autocompletion
    2 projects | /r/vim | 30 May 2023
    You can try https://github.com/neoclide/coc.nvim, the pre-requisite is to install nodeJS, then to install all the languages LSP. This works for me for Angular, Rust, JavaScript, Vimscript, etc

What are some alternatives?
