19-devshell-vs-shellfor

This example compares two dev shell styles for the same local package.

It includes:

• a generic mkShell shell,
• a Haskell-specific shellFor shell,
• one local package that both shells support, and
• a test suite run by nix flake check.

Useful commands:

nix develop .#generic
nix develop .#shellFor
nix build
./result/bin/mini-shell-choice
nix flake check
