  • JetBrains' unremovable AI assistant meets irresistible outcry

    I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.

    These two plugins are the bare minimum in my view.

    Treesitter gives you much better syntax highlighting based on a parser for a given language.

    https://github.com/neovim/nvim-lspconfig

    This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:

    https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...

    For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.

    pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server

    Best of luck! Happy hacking.

    Adding language support it neovim isn't very difficult once you're setup. I use nvim-lspconfig[1] and just about any language you could need is documented[2]. But like others have mentioned there are batteries included distributions of neovim if that's your cup of tea.

    If we can't find the basic usage in the documentation we can go to nvim-lspconfig's github repository. In there we look for a folder called server_configurations, this contains configuration files for a bunch of language servers.

  • Need help to set up the pbkit language server

    I am trying to set up the pbkit language server for protobuf files. Since it is not part of the nvim-lspconfig repo's server configurations, I have to figure the way out myself. It doesn't seem to be too difficult, as I can start from the bufls configuration there. The following is what I have at the moment:

  • Using nvim-lint as a null-ls alternative for linters
    4 projects | /r/neovim | 14 Aug 2023
    Personally, i think nvim-lint is the best alternative currently, specially so because it has no dependencies on external binaries. This guide assumes you already have your LSP set up with nvim-lspconfig (or an alternative like lsp-zero). You should also have an way to install the linters you are gonna need, i highly recommend Mason with mason-lspconfig.
  • The Future of the Vim Project

    Basically neovim can act as a client to a variety of different language servers (https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...) which give neovim IDE capabilities. This can be done in original Vim also but requires external plugins which can be a pain to compile and install. Neovim has it built in.

  • 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?
