nvim-treesitter-refactor VS nvim-lua-guide

Maybe this? nvim-treesitter-refactor

These days though I'm using the https://github.com/nvim-treesitter/nvim-treesitter-refactor plugin. It goes one step further and only highlights the matches that are in the same scope. Makes a big difference in a lot of programming languages where you use the same variable named in a lot of smaller functions/methods right next to each other.

My desires are not sated, but it seems quite nice. (I recall treesitter-refactor has a similar scope highlighter, but it could be a bit aggressive near root scope -- this might be a more gentle version.

Treesitter performance is a hard problem. First, check the following: 1. Do you use nvim_treesitter#foldexpr()? Try not to use foldmethod=expr in insert mode. Or just switch to nvim-ufo. 2. Do you use nvim-treesitter-refactor's highlight_definitions or highlight_current_scope? These features do slower the performance. Try to disable these features. 3. I've heard some language parser is not good in terms of performance. Since I don't write haskell, I can't help you here. But you can create issue in nvim-treesitter.

For instance, with plugins like nvim-treesitter-refactor and ray-x/navigator.lua, you can use a bunch of commands like "go to definition" and "smart rename" without an LSP server.

TS Refactor

get_node_text was removed from ts_utils. create a pull request to fix it, something like this: https://github.com/nvim-treesitter/nvim-treesitter-refactor/pull/33

If you have treesitter, you can use nvim-treesitter-refactor. It has the highlight_definitions option that will highlight the definitions of a variable.

Oh! I've actually never tried Emacs text navigation. My brief stint with Emacs was with Spacemacs (w/ the evil-mode plugin). If I knew any lisp when I had given Spacemacs a whirl then there's a chance I may have stuck with it. I've played with Clojure a bit. Ah, it appears that you're a data-eng -- heavy on the Python. Are you trying to mimic something that PyCharm provides? I'm just happy that LSP has come where it has in such little time and that's already improved working with code in various languages quite a bit. Neovim moves incredibly fast and having LuaJIT with support for Lua had completely opened the floodgates for ports of old Vim plugins and made way for newer ones with floating windows/floating terminals. There are two projects each with hundreds of stars on GitHub meant to mimic or one-up org-mode (one has an entirely new spec) with immense development activity. The one-up that Neovim has over Vim presently is tree-sitter (because the core team wrote a wrapper) and exposes a Lua interface for plugin devs that want to use it. It's been neat for themes and my new favorite find-and-replace plugin (https://github.com/nvim-treesitter/nvim-treesitter-refactor). Because there's type data coming from the AST, it's much less likely to have accidental replacements (if at all). It looks like Emacs is making some headway here, though: https://github.com/emacs-tree-sitter

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.
