nvim-metals VS nvim-dap

By multiple subprojects are they independent builds? Or just one big build with nested build files? I actually have a discussion related to this in here. Please to jump in there if that's the same issue you're having and comment on your situation. It'll be helpful to determine how to address it.

Use nvim-metals

elixir.nvim is a langauge plugin for Elixir. It is similar to nvim-metals in that is manages ElixirLS (Elixir's language server) and provides a complete experience over nvim-lspconfig.

Install https://github.com/scalameta/nvim-metals

But I haven't yet set up anything properly other than Debugpy. nvim-dap is very barebones, so I feel that the best way is to have an extra configuration plugin on top. Debugpy.nvim is a very specific frontend plugin, but there are also more general plugins like nvim-metals and vim-ultest which also offer integration with nvim-dap.

Yeah it's pretty good already and getting newer features everyday. I didn't want to hook up the vim I use everyday to a heavy editor so installed neovim alongside vim on my system and use this https://github.com/scalameta/nvim-metals (which I believe is the metals official way) and it's super straight forward to use.

Every software project is WIP to some extent, but that doesn't stop Neovim itself from having really high standards in documentation. A lot of Neovim plugins also have really high standards, such as nvim-metals.

nvim-metals (really thorough manual)

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.
