viaenv

These days, I write a lot of Go and a lot of Python (and some other languages in the mix). What's great is that I'm getting ideas from both ecosystems and find myself more productive.

In the Go world, I like Kelsey Hightower's envconfig for a simple application configuration from environment variables. I couldn't find something similar in the Python world, so I wrote viaenv which uses variable annotation.

One design decision I took is not to invent my own serialization format when getting lists & dicts from the environment (where everything is a string). I'm using JSON, there's really no need to invent yet another serialization format (as envconfig does).

The code itself is not that long (less than 150 lines of code). I'm showing it below:
