twilight.nvim VS nvim-treehopper

why not https://github.com/folke/twilight.nvim ?

I like that blockman just makes scoping subconsciously clear as I scan through code though. Whereas twilight is focused on.. uh, focus. :)

Don't know about animations, but you can highlighting the current line and dim the rest with Twilight.nvim.

There's an example in the following repo: https://github.com/folke/twilight.nvim (look at selene.toml and vim.toml)

This might be something twilight.nvim

Twilight is a Lua plugin for Neovim 0.5 that dims inactive portions of the code you're editing.

I am trying to set up nvim-treehopper and duplicating the suggested keymaps in a lua config.

Take a look at nvim-treehopper (https://github.com/mfussenegger/nvim-treehopper), a tree-sitter based plugin that lets you select regions of code

This copies the idea of nvim-treehopper. Just a work in progress hack (pretty usable though), but planning to make a full-fledged plugin, if someone else won't do it :) (Needless to say, my gists can be considered unlicensed, do whatever you want with them.)

I also suggest taking a look at this one : mfussenegger/nvim-treehopper

https://github.com/mfussenegger/nvim-ts-hint-textobject does what you are proposing.
