Neovim :InspectTree Tree-sitter
I had assumed that to interact with Tree-sitter in Neovim,
you still needed to use the utilities from nvim-treesitter.
Apparently that’s not the case —
Neovim has had a builtin :InspectTree
command that brings up the AST from Tree-sitter in a split window,
which is scrollbound
to the original window and highlights the selected node in both windows.
It also has a query editor, which I haven’t yet had the need for, but it’s good to know it exists.
