Allow activating virtualenvs via path about virtualfish

[justinmayer]

Hey Matthew. Could you elaborate regarding precisely what you are trying to accomplish? It's not clear from the brief description provided.

Activating a virtual environment, regardless of which tool does it, entails setting the shell's $PATH such that the environment's executables take precedence. VirtualFish is no different in that respect, and the operation performed is quite straightforward.

In other shells we just source path/to/venv/activate but this obviously doesn't work with fish

Well, in the virtual environments I have seen, a Fish-specific activation script is already included at your-virtual-environment/bin/activate.fish, so other than appending .fish to your usual invocation, I don't see any other differences in terms of process flow.

In any case, could VirtualFish source that file instead of using its own activation logic? Sure, but in the absence of presented evidence to the contrary, I don't believe that would accomplish anything, and the reasons why it doesn't activate via Virtualenv's activate.fish are already explained in the FAQ.

You're right 🤦

Thanks!
