upstream regression in kitty 0.24.4 (ValueError: invalid literal for int() with base 10: '')

Hi, I'm getting the following error trying to use the package: ValueError: invalid literal for int() with base 10: '' Here is the full stack trace

I am using Kitty 0.24.4 under MacOS 12.3 with Python 3.8.13 installed with Conda and Matplotlib 3.5.1

This module currently relies on running kitty +kitten icat --print-window-size as a subprocess. On kitty 0.24.4, this seems to fail with the following, at least on my end:

$ kitty +kitten icat --print-window-size

So this looks like a regression in kitty's tooling, for which someone has already opended an issue upstream: https://github.com/kovidgoyal/kitty/issues/4900

I'll leave this open until upstream rolls out a fix.

[jktr]

Actually, this seems to have already been fixed on kitty master: https://github.com/kovidgoyal/kitty/pull/4818

So you could wait for 0.24.5 to be released, run kitty nightly in the meantime, or downgrade.

[julianfritzsch]

Interestingly, with kitty 0.25.0 it works when using iPython but using a Jupyter console it still gives the same error.

[jktr]

kitty 0.25.0 and 0.25.1 have been released and are likely available in most distros' repos by now; both of them seem to work fine on my end. My thanks go out to @nertro for fixing this issue upstream.

Hi @julianfritzsch , I just want to ask if you have found any solution for this error on Jupyter Console?

[julianfritzsch]

Hi, unfortunately it does not work with the Jupyter console for me but I get an error

Error: Failed to open controlling terminal with error: open /dev/tty: device not configured

However, it works perfectly fine with iPython for me
