euporie: Exception 'TextArea' object has no attribute 'preferred_width'

Trying to use the inline plotting, I’m using kitty.

Here’s the code:

% matplotlib inline
import matplotlib.pyplot as plt
plt.plot([1, 2, 3, 4])
plt.ylabel('some numbers')
plt.show()

This will immediately exit to the terminal and print the following strace

The “colinear!” text you are seeing is OS-level standard error output from the kernel (reportlab prints directly to stderr in it’s c-extensions - see here).

The same thing happens with JupyterLab - output is printed to the terminal where the kernel was started rather than being displayed in the notebook:

There is an old IPython issue about this I remember from years ago: https://github.com/ipython/ipython/issues/1230

The issue mentions a nice IPython extension wurlitzer you can use to work around this:

Interesting. Feels like we’re getting closer!

The kitty graphics protocol allows you to do more complex things with images then sixel graphics, such as hide & show, duplicate, and move images. Currently I’m not making full use of it’s capabilities - I’m just clearing all images from a notebook and re-drawing them every time the display is drawn.

I’m already aware of some issues with with the way I implemented this (one is that images are cleared per notebook, which means that if you have multiple notebooks, only the images from one notebook will be displayed). I suspect the problem you are having may be related.

Rewriting the euporie’s kitty graphics code so images are shown, hidden, and moved without re-drawing them is on my to-do list.
