debugpy VS nvim-lspconfig

debugpy description from it's repository:

I'd love to see what it can do with https://github.com/microsoft/debugpy - and especially how it would handle vendored dependencies.

I read that nvim-dap-python uses debugpy which has all these configuration parameters of which one of them is `cwd` which represents the "absolute path to the working directory of the program being debugged".

Hey all, I'm not sure if this is normal or not but, when debugging with nvim-dap, nvim-dap-ui, and nvim-dap-python (which uses debugpy) over a remote session, dap runs exactly once and then closes the entire process. This even happens when I just call `require("dap").restart()`. It's pretty frustrating to deal with and is not something that I was used to when I used to debug with vimspector, which let me restart the debug remotely as many times as I wanted without killing the application that I was connected to. Is this happening for anyone else? How do I disable it? I didn't see anything in debugpy's configuration options. I'm rereading dap's vim :help but haven't found any mention of auto-close / terminate logic yet.

After testing I have the same situation. I reported this issue on GitHub, you can follow up.

vim.fn.sign_define('DapBreakpoint', {text='🛑', texthl='', linehl='', numhl=''}) dap.configurations.python = { { -- The first three options are required by nvim-dap type = 'python'; -- the type here established the link to the adapter definition: `dap.adapters.python` request = 'launch'; name = "Launch file"; -- Options below are for debugpy, see https://github.com/microsoft/debugpy/wiki/Debug-configuration-settings for supported options program = "${file}"; -- This configuration will launch the current file if used. pythonPath = function() -- debugpy supports launching an application with a different interpreter then the one used to launch debugpy itself. -- The code below looks for a `venv` or `.venv` folder in the current directly and uses the python within. -- You could adapt this - to for example use the `VIRTUAL_ENV` environment variable. return os.getenv("VIRTUAL_ENV") .. "/bin/python" or '/usr/bin/env python' end; }, }

You should take a look at DAP (Debug Adapter Protocol). There exist a Python module implementing this protocol (debugpy) and you can probably find some client applications that can hook into it (like this neovim plugin).

I suggest looking for blog posts about this, you're gunnuh wanna pick out a plugin manager and stuff. It's kind of like a package manager for neovim. You can install everything manually but usually you manually install a plugin manager and it gives you commands to manage the rest of your plugins.

These two plugins are the bare minimum in my view.

https://github.com/nvim-treesitter/nvim-treesitter

Treesitter gives you much better syntax highlighting based on a parser for a given language.

https://github.com/neovim/nvim-lspconfig

This plugin helps you connect to a given language LSP quickly with sensible defaults. You more or less pick your language from here and copy paste a snippet, and then install the relevant LSP:

https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...

For Python you'll want pylsp. For JavaScript it will depend on what frontend framework you're using, I probably can't help you there.

pylsp itself takes some plugins and you'll probably want them. https://github.com/python-lsp/python-lsp-server

Best of luck! Happy hacking.

Adding language support it neovim isn't very difficult once you're setup. I use nvim-lspconfig[1] and just about any language you could need is documented[2]. But like others have mentioned there are batteries included distributions of neovim if that's your cup of tea.

If we can't find the basic usage in the documentation we can go to nvim-lspconfig's github repository. In there we look for a folder called server_configurations, this contains configuration files for a bunch of language servers.

https://github.com/hrsh7th/nvim-cmp This is an autocompletion engine https://github.com/nvim-treesitter/nvim-treesitter This allows NeoVim to install parsing scripts so NeoVim can do things like code highlighting. https://github.com/williamboman/mason.nvim Not strictly necessary, but allows you to access a repo of LSP, install them, and configure them for without you actively messing about in config files. https://github.com/neovim/nvim-lspconfig Also not strictly necessary, but vastly simplifies LSP setup. https://github.com/williamboman/mason-lspconfig.nvim This lets the above two plugins talk to each other more easily.

This specific issue talks about fixing clangd for that error: https://github.com/neovim/nvim-lspconfig/issues/2184. The issue is ongoing for ccls AFAIK but for clangd, this has been discussed and fixed in the past already.

I am trying to set up the pbkit language server for protobuf files. Since it is not part of the nvim-lspconfig repo's server configurations, I have to figure the way out myself. It doesn't seem to be too difficult, as I can start from the bufls configuration there. The following is what I have at the moment:

I have configured neovim with lspconfig and mason. Added the suggested configuration of the lsp config(https://github.com/neovim/nvim-lspconfig) to ~/.config/nvim/after/plugin/lsp.lua Then I installed via mason the following language servers:

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.

Basically neovim can act as a client to a variety of different language servers (https://github.com/neovim/nvim-lspconfig/blob/master/doc/ser...) which give neovim IDE capabilities. This can be done in original Vim also but requires external plugins which can be a pain to compile and install. Neovim has it built in.

I'm struggling to get [sqlls](https://github.com/joe-re/sql-language-server) with [nvim-lspconfig](https://github.com/neovim/nvim-lspconfig) to use Postgres syntax.
