tox breaks ipython input/output when

[albertodonato]

Issue

When running ipython as a command in a tox env, the input and output are messed up. Terminal gets reset at every enter from the ipython shell. This seems to be due some conflict interacting with the console A workaround is to pass --simple-prompt to ipython, but this means ipython doesn't provide things like autocompletion.

Tested with tox 4.5.1 and ipython 8.13.1.

Environment

Provide at least:

• OS: Ubuntu 23.04 amd64
• pip list of the host Python where tox is installed:

$ pip list

cachetools    5.3.0
chardet       5.1.0
colorama      0.4.6
distlib       0.3.6
filelock      3.12.0
packaging     23.1

virtualenv    20.23.0

Output of running tox

Provide the output of tox -rvv:
