nvim-treesitter-context VS nvim-treehopper

It's for context and navigation, not completions. So it wouldn't replace nvim-cmp. It probably doesn't replace anything you already have unless you are already using a winbar. It combines features of treesitter-context, symbols-outline, and a file navigator but in a different presentation.

Not quite the same thing, but arguably a better alternative : https://github.com/nvim-treesitter/nvim-treesitter-context

For 2: https://github.com/nvim-treesitter/nvim-treesitter-context

I really like nvim-treesitter-context as an alternative for 1.

nvim-treesitter-context implements "sticky scroll" where, depending on where your cursor is placed, the top lines of your window will be replaced by the otherwise offscreen lines that declare what function you're in (e.g function test(...), the line that begins the current class (e.g. public class Student implements Person {), the variable name of the current table (e.g. local planets = {), etc.

There are a couple of plugins that do this.

For vim: https://github.com/wellle/context.vim

For neovim (much higher performance in my experience): https://github.com/nvim-treesitter/nvim-treesitter-context

I believe there's now also a VS code plugin for the same behavior, but I don't know what it's called.

Very different in my eyes, but I love nvim-treesitter-context. Definitely another tool in helping the brain parse code -- I think of it as helping with long range context, whereas blockman helps me focus on local context and makes scoping relationships more subconciously available.

You are looking for this: https://github.com/nvim-treesitter/nvim-treesitter-context

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.
