Filter .*\( and \).* in VENV if it is present

[Niapoll]

When I activate a Python virtual environment created with the venv module, I expect to see:

but instead I get:

This change removes any characters and brackets (if present) that should appear in the prompt

#29 Which python venv manager are you using? This may need re-arranging fallback order of env vars to read from. (e.g. a different var). This seems to me a bit of hard code.

I use the venv module for Python on macOS. It seems that in some versions of Python/venv, it's normal for the shell prompt to include something like (.venv) .

I agree it can look a bit messy. Maybe we can separate or format it more clearly using custom prompt expressions

It is strange that I could not reproduce this error you mentioned.

VIRTUAL_ENV            -- /project_name/env
VIRTUAL_ENV_PROMPT     -- env

using Python 3.14, python3.14 -m venv env, my prompt gives a normal user @ device (env): /project_name

I ran a quick check using pyenv 2.6.12 on ubuntu@sha256:c35e29c9450151419d9448b0fd75374fec4fff364a27f176fb458d472dfc9e54 to see how different Python versions (using the standard library venv module) set or omit VIRTUAL_ENV_PROMPT:

Python 3.8.20

No VIRTUAL_ENV_PROMPT variable.

Python 3.9.25

No VIRTUAL_ENV_PROMPT variable.

Python 3.10.19

.venv/bin/activate:60: VIRTUAL_ENV_PROMPT='(.venv) '

Python 3.11.14

.venv/bin/activate:57: VIRTUAL_ENV_PROMPT='(.venv) '

Python 3.12.12

.venv/bin/activate:57:VIRTUAL_ENV_PROMPT='(.venv) '

Python 3.13.9

.venv/bin/activate:57:VIRTUAL_ENV_PROMPT=.venv

Python 3.14.0

.venv/bin/activate:57:VIRTUAL_ENV_PROMPT=.venv
