Set of bash scripts that make bins installed in virtualenvs useful elsewhere.

Project description

Tools to install into a python virtualenv to make life easier. If you install virtualenv-bin into a virtualenv, you will get two useful programs.

venvbin

If you symlink to this program where it sits in a virtualenv and name the symlink for any program in the bin folder, executing the symlink will activate the virtualenv and then run the program, passing through all args and exit codes.

example

I want to install and use httpie, but I don’t want any of it’s dependencies interfering with my broader environment. Note: for this example, I use /opt/virtualenvs for all virtualenvs.

$ mkvirtualenv httpie
$ source /opt/virtualenvs/httpie/bin/activate
$ pip install --upgrade httpie
$ pip install virtualenv-bin
$ cd ~/bin
$ ln -s /opt/virtualenvs/httpie/bin/venvbin http
$ ~/bin/http example.org

venvlaunch

Running this lets you execute a program that is inside a virtualenv directly

example

Here we are going to run http from directly inside the virtualenv.

$ mkvirtualenv httpie
$ source /opt/virtualenvs/httpie/bin/activate
$ pip install --upgrade httpie
$ pip install virtualenv-bin
$ cd ~/bin
$ /opt/virtualenvs/httpie/bin/venvsymlinks
$ ~/bin/http --help
$ /opt/virtualenvs/httpie/bin/venvlaunch http example.org

installation

You can install virtualenv-bin using pip. There’s no point to installing this anywhere other then into a virtualenv you want to use it with.

$ pip install virtualenv-bin
