neovim-plugin VS nvim-lint

Definitely remove it, as it is an anti-pattern that gained popularity because individuals often copy content without careful consideration. As far as I know, it primarily originated from this Github post, which was created during the early days of Lua's growing popularity in Neovim as an attempt to reinvent the wheel.

I'm pretty sure we got started down the .setup road because of this article by norcalli a few years ago. It was published when plugins started using Lua and suddenly I went from seeing one or two plugins using .setup to literally every single plugin use it.

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.
