fix(treesitter): manually trigger parsing

[xiyaowong]

issue #1700

This is a common use case, and "treesitter-objects" is useful. (Note: I haven't explored why treesitter doesn't automatically parse after text changes.)

This bug has been bothering me for a long time but it seemed too strange to make an issue for.

Ideally we figure out why it's not working... but it makes no sense to me. Operations like undo all happen on the nvim side.

but it makes no sense to me.

🙋‍♂️I added a todo. It could be a simple bug for someone familiar with nvim-treesitter. Let’s wait for someone interested to contribute.

Actually I just tested this, and I can still reproduce if I undo and execute rapidly. Is there a way of removing the timer and making it triggered automatically? If not, we should maybe speed up the timer.

rapidly

In most cases, it wouldn't be so fast... You can adjust the time down without any impact. I copied it directly from my config. I try to reduce unnecessary operations as much as possible based on my own needs

Actually one line is enough 👀 :

au TextChanged * silent! lua vim.treesitter.get_parser():parse()
