SUMMARY:Flake schemas - Eelco Dolstra

DESCRIPTION:Flakes are a format for distributing Nix-based assets such as 
 Nix packages\, development shells\, CI jobs and NixOS modules. The flake s
 pecification doesn't impose any restrictions on the contents ("outputs") o
 f a flake\, and these can be arbitrary Nix values. While this makes flakes
  very flexible\, it means that there is no generic way to find out what a 
 flake provides\, or to check its correctness. To work around this\, tools 
 such as `nix flake show` and `nix flake check` have built-in support for a
  fixed set of flake output types such as `packages` and `devShells`. Unfor
 tunately\, this set cannot be extended by users to handle new flake output
  types.\n\nIn this talk\, I propose *flake schemas*\, which are essentiall
 y Nix functions that enumerate the contents of a flake output\, including 
 documentation\, checks and options. Flake schemas do not impose a type sys
 tem on flake outputs - it is entirely up to the schema function how it che
 cks the flake output. Flake schemas allow us to remove all output-specific
  code from commands like `nix flake {show\, check\, search}`\, making it e
 asier for developers to introduce new output\ntypes.
