nvim-lint VS LunarVim

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.

Try out https://github.com/mfussenegger/nvim-lint for linting tools, it integrates with nvim diagnostics module, might cover all use cases of null-ls for someone shopping around.

People looking for alternative can check these projects: - nvim-lint - formatter.nvim

For linting, I would recommend nvim-lint. Again the same step as before, a little bit of setup code to register your linter and you're good to go!

This will be the third linting solution to make use of the [Neovim Diagnostic] module after null-ls and nvim-lint. All can co-exist, all have the pros and cons.

I use nvim-lint (https://github.com/mfussenegger/nvim-lint), but I still don't know exactly how to achieve your goals with it. My hunch is that it should be somewhat straightforward, since Lua code could be used to provide the executable command (i.e. if in poetry project then cmd =poetry run ...else if ... then ... end)

It's not obvious from the website, but this is the blog of GitHub user @mfussenegger, who is a Neovim core member, one of the primary maintainers of Neovim's LSP client implementation, and the other of several excellent plugins.

https://github.com/mfussenegger/nvim-lint works with the diagnostics API that was created after LSP was added, to allow non-LSP to use diagnostics API. Meaning you can see LSP and linting in the same interfaces if you use this API.

As part of my work-in-progress Neovim [plugin]([https://github.com/nat-418/tcl.nvim)(https://github.com/nat-418/tcl.nvim)) for Tcl development, I added support for Nagelfar syntax checking in the nvim-lint plugin. This provides inline checking for errors as seen in the attached screenshot. If anyone has any ideas on how to create a Tcl Language Server, or knows of a project already working on one, I would be very interested to know about it.

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 .
