The GHC Packaging Ecosystem

on YouTube ↗01h 32m

" summary

Overview of how GHC treats libraries as concrete, registered units and how Cabal/Hackage/ghc-pkg/cabal-install actually interoperate: history from 2003 to today (Cabal → cabal-install, Hackage, hackathons since 2006), ghc-pkg writes a binary package.cache for fast startup, GHC no longer depends on Cabal, Hackage supports trustless mirrors, cabal-install produces opaque installed package ID strings so multiple instances of the same source version can coexist, tools construct a package environment by stacking package databases on disk.
