I saw something very cool recently and was wondering can we get it inside opentui.

Cursor styles on hover.
The TUI shown in the video is ampcode.

Hi, is there any chance I can explore this and maybe contribute on this? Would love to do it.
Thanks

Hi @kommander @simonklee , I was reading and searching about it, and got to know that many native CLI don't support cursor hover styles natively. Umm, I do have some implementation written but I would like to know if I can do it or how you guys expect it to work?
Currently I am doing a similar impl as the CursorStyle with mouseOut and mouseOver events within recheckHoverState().

Hi @viralcodex it cannot be guaranteed to work in all terminal emulators, but that's fine, many features depend on the terminal.

If there is a way to detect support, it would be good to add it to terminal.zig capabilities.

There are methods to setCursorStyle on the renderer, I would probably add the option there.

It needs to make sure it is properly reset in the shutdown sequence in terminal.zig if not already done with the current cursor reset.

Hi @kommander, thanks for clarifying. Yeah I started from there it felt better to have a separate MouseHoverStyles using OSC 22 Escape Characters, not only pointer but also blocked/busy state as well.
Sure, will look into it if it is feasible to extend in the current cursor implementation and raise a PR. If anything is needed to be changed, will update accordingly in review
