Rich Tracebacks fail on Jupyterlab

[krassowski]

Description

Rich tracebacks are broken on Jupyterlab. Relevant Rich issue here.

What appears to be happening is that the temporary file where Jupyter runs the cell code from as been removed from the filesystem when Rich comes to inspect it.

Rich will walk the frames in the exception with walk_tb, and look at f_code.co_filename to get the code. But these files don't exists. I'm not certain if the paths are incorrect, or the file as been removed.

Reproduce

from rich.traceback import install
install(show_locals=True)
1/0

Note the absense of code snippets in the traceback. Rich Tracebacks generally show a snippet of relevant code, more than the standard Python tracebacks. This did work in Jupyter until some point last year.

@willmcgugan I believe you fixed this issue in Textualize/rich#2754?

[willmcgugan]

Worked around it. The code from the cells is available via the linecache module.

[davidbrochart]

Great, I'm closing this issue then.
