There is no cursor in command line (FreeBSD)

[A1-Triard]

Runtime Environment

• Operating system and version: FreeBSD 12.1-RELEASE-p10
• Terminal emulator and version: xfce4-terminal 0.8.9.2 (I've tried also virtual tty with same result, so I suppose it can be reproduced with any terminal emulator)
• Python version: 3.7.9 (I've tried python 2.7 with same result, so I suppose it can be reproduced with any python version)
• Ranger version/commit: 1.9.3
• Locale: ru_RU.UTF-8

Current Behavior

There is no cursor in command line after after pressing ':' key. I can see cursor: it is stuck in screen top line and don't move then I type command.

Expected Behavior

Cursor appears in command line and react on pressing keys.

If you point me to a direction, I can try to do further investigation.

Hmm, I'd expect this is because of how we use ncurses. Maybe you could ask for help on their tracker or in their IRC channel? Just to help you find out what the issue on our side is/could be.

Also, I gets a warning at every start:

Warning: Subwindow size out of bounds for <ViewMiller> (x = 0, y = 18895760, hei = 39, wid = 136)

Couldn't it be related to the cursor issue?

[toonn]

Do you have a vertically large display? I guess it could be related.

[A1-Triard]

No. 1366x768, 41 lines in maximized console window.

[toonn]

Seems like some sort of initialization problem, because of the y value. That should be the vertical position of the window's upper left corner. I assume your display doesn't have 18 million vertical pixels?

[A1-Triard]

I can try to debug this if you show me some key code points.

[toonn]

Maybe the setup_curses method in ranger/gui/ui.py? I'm not really sure where to start with this.

[A1-Triard]

For now, I have found, that if add the following code after the self.paryx = self.win.getparyx() line in gui/displayable.py

if self.paryx[0] > 30000:
    self.paryx = (0, 0)

it fixes cursor horizontal coordinate: it still stays in top line, but correctly moves in horizontal direction then I type a command.
