Option to disable the development environment

[srid]

Haskell developers will always remain the primary audience of haskell-flake. For users who just want to package the Haskell app without needing the full-blown development environment, the following configuration is useful:

haskelProjects.default = {
  buildTools = _: {
    cabal-install = null;
    ghcid = null;
    hlint = null;
    haskell-language-server = null;
  };
}

(These just disable the default build tools added by haskell-flake).

However, this configuration does not prevent the addition of devShell itself that is going to remain unused by these users.

From an API standpoint, how can we provide a simpler option to disable the whole development shell and friends for this target audience (non-Haskell developer users)?

Simplest API I can think of,

haskellProjects.<name>.development = false;

... should disable the devShell injection entirely, thus all of buildTools becomes unused. But since buildTools (EDIT: also the check options) now becomes contingent on this new development flag, perhaps we should move it under that as well, viz.:

haskellProjects.default = {
  packages = { };
  overrides = self: super: { };
  development = {
    enable = true; # True by default
    buildTools = hp: {
      ghcid = null;
      fourmolu = hp.fourmolu;
    };
    hlintCheck.enable = true;
    hlsCheck.enable = true;
  };

development = false can also disable the checks; leaving packages only.
