Support for rich outputs in jupyter notebooks about rich HOT 5 CLOSED

I've added experimental support to v0.8.6, now on pypi.

If you do from rich.jupyter import print you can print any Rich renderable to the notebook.

I did some experimentation, and I was correct about Jupyter wrapping stdout. isatty returns False, so Rich disables ANSI styles -- even though Jupyter is capable of rendering them. If I force Rich to enable styles they do work.

Another issue is detecting the size of the terminal. When running in Jupyter, the size is detected as the size of the terminal running the server, not the output area on the screen. This leads to things wrapping incorrectly and breaking tables etc.

I'm sure some form of integration is possible. Still thinking of how it should work. Let me know if you have any ideas on that front.

small correction, jupyter notebooks does support ASCII colors but the default settings of Rich console does not detect its and strips away the colors. Any suggetions to fix it?

I don’t see why not. If it’s just a matter of adding that html_repr method, it’s not a lot of work.

Rich will disable colours if it doesn’t detect a terminal. It calls ‘istty’ on the file object. I’m guessing that Jupyter is wrapping stdout and breaking that somehow. I’ll look in to that, I’m sure there is a simple workaround.

Awesome!
Works really well even though the width is fixed rendering is proper
Thanks for being super responsive 😄
