Did you read :help guicursor ?

I did:

blinkwait{N}				*cursor-blinking*
		blinkon{N}
		blinkoff{N}
			blink times for cursor: blinkwait is the delay before
			the cursor starts blinking, blinkon is the time that
			the cursor is shown and blinkoff is the time that the
			cursor is not shown.  The times are in msec.  When one
			of the numbers is zero, there is no blinking. E.g.: >
				:set guicursor=n:blinkon0

This setting had no effect.

Currently its not possible to make the cursor not to blink. I'll eventually fix this at some point, but any PRs are welcome.

@vhakulinen thank you for your kind answer. Sadly, I don't have the knowledge to contribute yet. Please to update this issue if there's any change.

@vhakulinen +1 . Blinking cursor is distracting.

Nonblinking cursor added (using guicursor).

Relevant part in gnvim's documentation:

gnvim/runtime/doc/gnvim.txt

Lines 47 to 53 in 4f7c547

Cursor *gnvim-cursor*
*gnvim-cursor-blinking*
Gnvim's cursor can be set to blink with `guicursor`.
Make cursor blink: `set guicursor+=a:blinkon333`
Make cursor not to blink: `set guicursor+=a:blinkon0`

Non blinking cursor might be your new default, depending on your guicursor value.

Currently the non blinking cursor is "just" set to 50% opacity. Anyone interested in implementing similar functionality as TUI has (inverted fg/bg colors under cursor) and is up for some coding can checkout #42 (comment).

Awesome! I was diving through the code along the week, after seeing your implementation I think it was better that you were able to do it though.

BTW, this talk has good resources to understand ropes logic (which I was unaware of): https://www.youtube.com/watch?v=SKtQgFBRUvQ

I wouldn't pay too much attention to the gnvim's "rope". Its there, it works and has tests so you don't break it. It most likely is not superior in any way to just using 2D array in this case, which (I think) neovim-gtk does, and probably all the other GUIs too. But it was fun to write and neat to use 😈
