incremental parser support about language-tools HOT 2 CLOSED

Yes, of course we can consider using it :) Solving performance problems is the purpose of establishing this project.

Quick preview for what volar parser using:

There are currently no obvious performance problems with regex, because the usage of regex is very small, and in the case of on-demand calculation, regex will not be calculated if <template lang="pug">, <style> block is not changed.

But we have performance problems from typescript's getStart(), getStart() is very expensive, and the diagnosis will be significantly lagging when ref sugar is used extensively in <script setup>. Replacing typescript with tree-sitter seems to solve this problem.

The project is still changing rapidly, discussing efficiency in github may be very low, you can find me on discord if you need, my id is johnsoncodehk#0495.
