Usage¶

Insert the lines

import sys
import subprocess

try:
    import berhoel.cmd_line_history
except ImportError:
    # checking if python is running under virtualenv of venv
    is_venv = (
        # This handles PEP 405 compliant virtual environments.
        (sys.prefix != getattr(sys, "base_prefix", sys.prefix))
        or
        # This handles virtual environments created with pypa's virtualenv.
        hasattr(sys, "real_prefix")
    )

    subprocess.check_call(
        [sys.executable, "-m", "pip", "install"]
        + ([] if is_venv else ["--user"])
        + ["pyCmdlineHistory",]
    )

to “~/.pystartup” file, and set an environment variable to point to it:

export PYTHONSTARTUP=${HOME}/.pystartup

in bash.

This will locally install the module for each python you are calling.
