No history in python3 inside the virtualenv

[Phyks]

Hi,

Not sure if this issue is pew-specific or not, but I could not find much information on it… Inside a virtualenv (pew workon venv), I do not have history across different calls of Python.

Is it expected? Is there a way to recover an history?

Thanks!

This is a known Virtualenv bug

I already noticed it before, but I didn't dig to the root cause.

The only solution is a rewrite of virtualenv

I think that adapting virtualenv-rewrite might work.

Ok, will follow this issue. Thanks!

As a workaround, here is my .pythonrc (loaded thanks to export PYTHONSTARTUP=~/.pythonrc) :

import atexit, os, readline, sys
if sys.version_info >= (3, 0) and hasattr(sys, 'real_prefix'): # in a VirtualEnv
    PYTHON_HISTORY_FILE = os.path.join(os.environ['HOME'], '.python_history')
    if os.path.exists(PYTHON_HISTORY_FILE):
        readline.read_history_file(PYTHON_HISTORY_FILE)
        atexit.register(readline.write_history_file, PYTHON_HISTORY_FILE)
