What Python can learn from Haskell packaging

Description

Domen Kožar - What Python can learn from Haskell packaging [EuroPython 2016] [18 July 2016] [Bilbao, Euskadi, Spain] (https://ep2016.europython.eu//conference/talks/what-python-can-learn-from-haskell-packaging)

Haskell community has made lots of small important improvements to packaging in 2015. What can Python community learn from it and how are we different?


Haskell community has been living in "Cabal hell" for decades, but Stack tool and Nix language have been a great game changer for Haskell in 2015.

Python packaging has evolved since they very beginning of distutils in 1999. We'll take a look what Haskell community has been doing in their playground and what they've done better or worse.

The talk is inspired by Peter Simons talk given at Nix conference: [Peter Simons: Inside of the Nixpkgs Haskell Infrastructure][1]
