- TUI: Fix a case where the cursor was not displayed after hiding the
cursor and then setting it to be displayed again.
- Change to reset everything before setting guicursor.
fixes#12800close#12811
Steps to reproduce:
nvim -u NORC
:set termguicolors
:hi nCursor guifg=red guibg=red
:hi iCursor guifg=green guibg=green
:hi cCursor guifg=blue guibg=blue
:set guicursor=n:block-nCursor,i:hor25-iCursor,c:ver25-cCursor
:set guicursor-=c:ver25-cCursor
Actual behaviour: Cursor is a blue vertical.
Expected behaviour: Cursor should be the default color block.
It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.
- Use this to properly test cursor shape events.
- tests: update screen_basic_spec to use `screen:expect` short form.
Clearer than using `screen:wait` directy.
