kakoune-lsp VS nvim-cmp

Kakoune with LSP (gopls).

You could dive into installing kak-lsp, which will provide the code intelligence features you want. Kakoune doesn't do windowing on it's own, so your going to need to rely on something like tmux or a terminal emulator that does similar, such as wezterm, or even a tiling window manager (which is what is being used in the video). Kakoune really needs a lot of time invested to configure well though.

Why do you need vscode? Kakoune supports code actions, so this should work in the editor with the best editing model ever. See lsp-code-actions from https://github.com/kak-lsp/kak-lsp.

In addition, rather than using its own full-fledged programming language for plugins or choosing to use a specific programming language, it provides a limited configuration language that's closer to a domain-specific language and to be used as a "glue" between Kakoune and programs written in any language. For example, the kak-lsp plugin uses a program written in Rust that is integrated with Kakoune with a thin wrapper of Kakoune's configuration language.

If you're having problems with these capabilities, try to look at the kak-lsp debug output: https://github.com/kak-lsp/kak-lsp#troubleshooting

kak-lsp doesn't print to *debug* under normal operation. If you want to check on kak-lsp, enable verbose logging as described here and tail -f the log file.

So, since pretty much everything happens through a shell, you can use anything that produces an executable to write your logic. kak-lsp, for example, is written in Rust, with some kakscript to define the commands, hooks and options a user needs to interface with it.

Doing a fast scan on the commit history this is probably related to https://github.com/hrsh7th/nvim-cmp/pull/1689 . Hope it helps.

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.

Edit: Solved I only had to do this

toggling sources by Treesitter context

But today I'm a different person, and I'm sure that this is the right decision. I already gave a spiel on the cmp PR, but lemme copy-paste my response for those that weren't following the issue or don't check their GitHub notifications:

EDIT: I was able to reproduce the issue with a simplified nvim-cmp init.vim - posted here: https://github.com/hrsh7th/nvim-cmp/issues/1728

You need to add nvim-cmp and cmp-nvim-lsp

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?

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 :)
