lsp_signature.nvim VS LunarVim

However, many language clients are indeed sensitive to the latency of language servers like https://github.com/ray-x/lsp_signature.nvim and https://github.com/hrsh7th/nvim-cmp, and I do not have the ability to improve them.

I'm not sure if I don't have any personal info in my dotfiles repo, so I keep it private ^^'. But I had exact same issue as you are describing and I got it to work as expected with ray-x/lsp_signature.nvim.

https://github.com/ray-x/lsp_signature.nvim if you are not using cmp

you might want to try ray-x/lsp_signature.nvim. It gives you that when typing a function. pretty neat if you are not so sure about the params and you can read the documentation.

I have tried to find a solution to this using both noice.nvim and cmp. I ended up using https://github.com/ray-x/lsp_signature.nvim which has this behavior out of the box. Also provides some additional features like showing the signature inline.

Tried poking around, but could make anything work. I even installed ray-x/lsp_signature.nvim by mistake, and kept it because it's pretty good.

nvim-lspconfig, nvim-treesitter, and lsp_signature.nvim using my distribution's package manager (not sure if I need the last one, though). Treesitter works with my minimal config and highlights all code as expected, and for LSP I have the :Lsp... commands so the plugin gets loaded - but I can't find a way to configure it.

the issue on plugin maker's github page and my (essential) config so far )

LunarVim

I would suggest to start getting into vim by first trying out popular vim keybinding plugins available on your favorite code editor and get used to those first. Then, if you want to dive deeper into the power of Neovim, try out popular configs like LazyVim, LunarVim, NvChad... Taking Neovim from a mere text editor to a full-featured IDE with features like intellisense, debugging, testing, etc... on your own takes quite a lot of work and configuration.

I used Helix for a while due to its support for LSP out-of-the-box, which my Vim config at the time couldn't live up to. I switched back to NeoVim after finding LunarVim[1] which had everything I was trying to get setup in my own config.

I'll admit I didn't look into it, but Helix sounds like something like LunarVim (https://www.lunarvim.org/)

Personally I much prefer that the editor NOT ship with something like that by default, especially when it's so easy to set up. I have several different vim config I use, including a pretty bare-bones one for headless systems, and I much prefer the ability to customize something very specifically.

Build tools that can compose together, rather than a single do-it-all tool. That is the power of the low level editors vs IDE's.

I can't comment on any implementation details, but at least with LunarVim (which I use for daily coding), a slowdown when interacting with LSP is very noticeable. Some others have attested to this on a GitHub issue.

I'm not doubting your experiences with the lack of a slowdown, but there is truth that others do experience it. That might be more of a problem with LunarVim itself rather than Vim, but how likely am I (as someone who would like to avoid what he calls "config hell") or other newcomers to avoid whatever pitfalls there are, if a distribution designed for ease of use by people who know better fall into them?

Anyways, although i have not used them, LazyVim and LunarVim comes highly recommended. You can try these and see what suits you .
