- Single file
- Runnable
- Reproducible
- 0 setup (no hard build / install)
- Using Nix-"shebang" line (https://nixos.org/nix/manual/#use-as-a-interpreter)
These are useful as a starting point for playing around and experimenting with Haskell packages, without caring too much about build environment or tools (Cabal, Stack, Nix, etc.).
We DO NOT encourage this hack-ish ugly one-liner style for production code.
For production we recommend using organized Nix source trees with as much https://dhall-lang.org/ as possible.
Credit goes to these wonderful packages and their creators:
