From 45e606b1fddbfeee8fe28385b5371ca6f2fba71b Mon Sep 17 00:00:00 2001 From: Riley Bruins Date: Wed, 18 Dec 2024 10:48:33 -0800 Subject: feat(treesitter): async parsing **Problem:** Parsing can be slow for large files, and it is a blocking operation which can be disruptive and annoying. **Solution:** Provide a function for asynchronous parsing, which accepts a callback to be run after parsing completes.
