--prompt . : the dot causes the basename of the current directory to be used

[okken]

What's the problem this feature will solve?

I'd like an easy way to have the prompt reflect the directory the env was created in.

Describe the solution you'd like

I'd like --prompt . to use the basename of the current directory for the prompt, similar to what venv does.
More specifically, the prompt should be the directory in parentheses.

$ mkdir foo
$ cd foo
$ virtualenv venv --prompt .
$ source venv/bin/activate
(foo) $ 

Alternative Solutions

We could change the default prompt to be this. that'd be cool.

Additional context

This as been in the venv implementation of Pyhon since Python 3.9.something.

Python 3 documentation: https://docs.python.org/3/library/venv.html#api

prompt – a String to be used after virtual environment is activated (defaults to None which means directory name of the environment would be used). If the special string "." is provided, the basename of the current directory is used as the prompt.

If anyone puts in a PR with tests I'd be happy to accept, merge and release it. Thanks!

I could attempt a PR, unless you were planning on working on it @okken?

@rkm Go for it. I'd love to see it implemented.

So close.. May I ask if we could include parentheses and a space, so it could be (foo) $ instead of foo$?

So you want to change how the bash activation scripts renders prompts? You know the drill: open an issue and then a PR. 😎
