Description

I reported this bug to the extension (https://github.com/microsoft/vscode-python/issues/11958) but they confirmed that this behavior does not happen in VSCode. Thus, it must be some issue with Theia.

Steps to cause the bug to occur

  1. Open theia using the python image

docker run -it --init -p 3000:3000 -v "$(pwd):/home/project:cached" theiaide/theia-python

  1. Start a python interactive session and enter this:
class A():
	def _repr_latex_(self):
		return "$\psi$"
  1. In next cell, run A() to create an object of this class and have it be printed

Actual behavior

Latex is not rendered image

Expected behavior

Latex should be rendered, like it is in markdown mode image

Additional Information

  • Jupyter server running: Local
  • Extension version: 2020.1.58038
  • Python and/or Anaconda version: 3.7.0

Research direction
Investigate how Theia processes IPython rich output, specifically ` repr latex `. Look at the Jupyter integration code, possibly in the notebook related extensions. Compare with VSCode's implementation to understand the difference. Check if Theia's Markdown rendering is applied correctly to LaTeX strings. The file likely involved is in the 'packages' directory for notebook or output rendering.
