Nix types.

Documentation

data NixOpts

Nix configuration. Parameterize by resolver type to avoid cyclic dependency.

Constructors

NixOpts

Fields

• enable :: !Bool
• pureShell :: !Bool
• packages :: ![Text]

  The system packages to be installed in the environment before it runs

• initFile :: !(Maybe FilePath)

  The path of a file containing preconfiguration of the environment (e.g shell.nix)

• shellOptions :: ![Text]

  Options to be given to the nix-shell command line

• addGCRoots :: !Bool

  Should we register gc roots so running nix-collect-garbage doesn't remove nix dependencies

Instances

Show NixOpts

Defined in Stack.Types.Nix

Methods

showsPrec :: Int -> NixOpts -> ShowS

show :: NixOpts -> String

showList :: [NixOpts] -> ShowS

data NixOptsMonoid

An uninterpreted representation of nix options. Configurations may be "cascaded" using mappend (left-biased).

Constructors

NixOptsMonoid

Fields

• enable :: !(First Bool)

  Is using nix-shell enabled?

• pureShell :: !(First Bool)

  Should the nix-shell be pure

• packages :: !(First [Text])

  System packages to use (given to nix-shell)

• initFile :: !(First FilePath)

  The path of a file containing preconfiguration of the environment (e.g shell.nix)

• shellOptions :: !(First [Text])

  Options to be given to the nix-shell command line

• path :: !(First [Text])

  Override parts of NIX_PATH (notably nixpkgs)

• addGCRoots :: !FirstFalse

  Should we register gc roots so running nix-collect-garbage doesn't remove nix dependencies
