To avoid clashes with packages installed on your system, FlexGet can be installed in a Python virtualenv. A virtualenv is similar to a chroot, but specific to Python packages. Creating a virtualenv is a simple process. The virtualenv will contain its own Python interpreter and its own versions of downloaded dependencies, separate from the system's packages.

Creating a virtualenv is a standard procedure in a Python web application deployment.

Let's create a folder in which to create the virtualenv:

mkdir ~/virtualenv # or any name you prefer
cd ~/virtualenv

Now, create the virtualenv itself and make it relocatable. For some reason, we have to create a regular virtualenv before making it relocatable:

I had to deal with bilingual strings from an XML API (Canadian weather
website) in a short script that I wrote. I wanted a way to handle
those that was lightweight and simple.

First we define a sum type for languages that we support. Thanks to
this type, we can ensure through exhaustive pattern matching that we
have always included all supported languages in a string. It is so
simple to implement that it remains simple while still making use of
the safeties of the type system.
