toggle-lsp-diagnostics.nvim VS nvim-dap

For files I didn't write and trigger many errors I toggle just all diagnostics, I use a plugin for that https://github.com/WhoIsSethDaniel/toggle-lsp-diagnostics.nvim

Are enable/disable fairly new (also show())? I don't remember them when I was writing [toggle-lsp-diagnostics](https://github.com/WhoIsSethDaniel/toggle-lsp-diagnostics.nvim). I recall having to use display() (which was and remains undocumented AFAIK). I know about the vim.diagnostic / vim.lsp.diagnostic name switch, but I don't recall these functions being available in 0.5.0. I suppose what I'm asking is "do I need to use display() if I want to support 0.5.0?"

You can try https://github.com/WhoIsSethDaniel/toggle-lsp-diagnostics.nvim.

There are DAP extensions for both Vim (e.g. https://github.com/puremourning/vimspector) and NeoVim (https://github.com/mfussenegger/nvim-dap). I can't speak as to the experience in detail (I think I briefly played with nvim-dap a year or two ago), but I suspect that for most it will be good enough.

Also, you can set up debugger integration with https://github.com/mfussenegger/nvim-dap .

You could use nvim-dap with nvim-dap-python.

I'd suggest starting with a Neovim distro that makes things work for you and as you get familiar you can transition to a more custom configuration as you see fit. If you want to do it by yourself then the most popular plugin for debugging in Neovim is nvim-dap and there is also an extension for Python to give you a more ready to go config instead of doing it yourself. You should read the docs of those 2 to see how you should customize accordingly your configuration.

(neovim only) nvim-dap

https://github.com/mfussenegger/nvim-dap + https://github.com/theHamsta/nvim-dap-virtual-text should be able to do it, I think?

If you want to debug types in TypeScript, you could use marilari88/twoslash-queries.nvim. If you would like to debug TypeScript/JavaScript code, then you need mfussenegger/nvim-dap, you could read this article: Debugging using DAP to understand how to set up it.
