How does it work?

It’s just a virtualenvwrapper extension!

If you are already using that, just

$ pip install govenv

And next time you make a virtualenv by using mkvirtualenv it will create a gopath directory in your venv folder to hold all your golang source. Now, whenever you activate that it will set your GOPATH and PATH, and return it to its previous setting when you deactive.

We also add an alias, if you don’t have it:

$ gohere

Which will add your current working dir to the end of the GOPATH (useful for testing local code during development.

It’s extremely simple, you should just look at the source: gopath.py
