neodev.nvim VS nvim-lua-guide

Also the vim API signature is not available using the fennel-language-server In lua you can install neodev and you will get some nice lsp suggestions with the vim API, this is sadly not possible in fennel right now

Other than the root_dir problem, I think the lsp server might have been attached but configuration would be different. For instance, if one is using folke's neodev for API completion (https://github.com/folke/neodev.nvim/issues/158) it would work differently for nvim config files and other lua workspaces.

Try to debug what happens on exit, maybe https://neovim.io/doc/user/starting.html#-V works. Regarding nvim-cmp being slow, do you have https://github.com/folke/neodev.nvim installed? If yes, try removing it and checking if it's an issue. It's been slowing down my completion for a while until I pinpointed the issue (and it was slowing it down always, not just when editing lua code).

You can try neodev.nvim. It's really great especially if you're planning for plugin development.

Are you using https://github.com/folke/neodev.nvim ?

Okay i figured it out myself https://github.com/folke/neodev.nvim provides lua files with the required type signatures.

Nvim Lua guide

My main struggles beyond a simple problem are just the inability to find a way to easily debug things and the general process for setting up a plugin. I mostly work with Python/Jupyter, some C and Lua/Bash scripts, and usually you can either write tests/print debug for smaller scale things or get some stack trace if you have an error. With Neovim development, it just feels like there's nothing more besides update plugin, try on neovim, fail, bash head against wall, and repeat, and that doesn't quite seem efficient or correct - I'm sure there's something out there that should make the process easier. I tried looking online but I haven't found many that really fit my needs (most of the resources here seem more targeted towards creating your own init.lua, and Luadev plugin's commands are all broken (:Luadev-RunLine and any other command keeps telling me I got some trailing space). I'm really just looking to see how to make a snippet library, but there doesn't seem to be much that helps me. If someone could let me know how they debug their plugin or point me to any external resources, please let me know!

I have no guidance for the first point. For the second, checkout the neovim lua guide or : lua-guide

A quick google search turned up this codeacademy class on learning to program in Javascript. I didn't vet the whole thing, but it appears to assume you know nothing, which is what you need. If you go through that, you can then consume one of the resources that /u/luascriptdev post to equate that back to Lua. Again, the concepts translate.
