Problem:
Treesitter injections are slow because all injected trees are invalidated on every change.
Solution:
Implement smarter invalidation to avoid reparsing injected regions.
- In on_bytes, try and update self._regions as best we can. This PR just offsets any regions after the change.
- Add valid flags for each region in self._regions.
- Call on_bytes recursively for all children.
- We still need to run the query every time for the top level tree. I don't know how to avoid this. However, if the new injection ranges don't change, then we re-use the old trees and avoid reparsing children.
This should result in roughly a 2-3x reduction in tree parsing when the comment injections are enabled.
This function replaces both vim.treesitter.get_node_at_pos() and
vim.treesitter.get_node_at_cursor(). These two functions are similar
enough that they don't need separate interfaces. Even worse,
get_node_at_pos() returns a TSNode while get_node_at_cursor() returns a
string, so the two functions behave slightly differently.
vim.treesitter.get_node() combines these two into a more streamlined
interface. With no arguments, it returns the node under the cursor in
the current buffer. Optionally, it can accept a buffer number or a
position to get the node at a given position in a given buffer.
Problem:
vim.treesitter does not know how to map a specific filetype to a parser.
This creates problems since in a few places (including in vim.treesitter itself), the filetype is incorrectly used in place of lang.
Solution:
Add an API to enable this:
- Add vim.treesitter.language.add() as a replacement for vim.treesitter.language.require_language().
- Optional arguments are now passed via an opts table.
- Also takes a filetype (or list of filetypes) so we can keep track of what filetypes are associated with which langs.
- Deprecated vim.treesitter.language.require_language().
- Add vim.treesitter.language.get_lang() which returns the associated lang for a given filetype.
- Add vim.treesitter.language.register() to associate filetypes to a lang without loading the parser.
If nothing matched in match_from_hashbang, also check the file extension table.
For a hashbang like '#!/bin/env foo', this will set the filetype to 'fooscript'
assuming the filetype for the 'foo' extension is 'fooscript' in the extension
table.
The original motivation for this change came from developping
https://github.com/neovim/neovim/pull/22159, which will require adding
more autocommand creation to Neovim's startup sequence.
This change requires lightly editing a test that expected no autocommand
to have been created from lua.
- Render node ranges as virtual text
- Set filettype=query. The virtual text is to avoid parsing errors.
- Make sure highlights text is always in view.
Problem: Move language files are not recognized.
Solution: Recognize Move language files. (Amaan Qureshi, closesvim/vim#11947)

Problem: .clangd and .stylelintrc files don't get a filetype.
Solution: Use yaml for .clangd and json for .stylelintrc files. (Mark
