Performance issues about boop HOT 5 CLOSED

I think most of the performance can be won by the third solution. This is a common solution in most IDEs which also use regex-based syntax highlighting.

Not sure what you mean by the following:

Only highlight viewport, and only when changed

Is it when viewport has changed (e.g. resizing, scrolling) or upon changing the content?

Is it when viewport has changed (e.g. resizing, scrolling) or upon changing the content?

Both, though I'd say the first step would be only when changing the content, on a line-per-line basis. Since it's using NSAttributedString in the background, resizing and scrill won't change anything if the whole thing already got rendered.

Wouldn’t this mean that pasting large amount of text would be slow if it had to parse all the text to highlight it.

I can see an issue if it only highlights the text that is visible in the viewport. Scrolling and resize would not update the highlighting.

Correct, first paste would be a bit slow but I think that's an ok tradeoff for a first improvement. The biggest issue right now is the slowness when typing in a large document

Fixed in release 1.3.0
