-- Please update doc/{flavours.md, user-settings.md} when changing this file.
-- | 'Flavour' is a collection of build settings that fully define a GHC build.
-- Note the following type semantics:
-- * @Bool@: a plain Boolean flag whose value is known at compile time.
-- * @Action Bool@: a flag whose value can depend on the build environment.
-- * @Predicate@: a flag whose value can depend on the build environment and
-- on the current build target.
data Flavour = Flavour {
-- | Flavour name, to select this flavour from command line.
name :: String,
-- | Use these command line arguments.
args :: Args,
-- | Build these packages.
packages :: Stage -> Action [Package],
-- | 'native', 'gmp', 'ffi'.
bignumBackend :: String,
-- | Check selected backend against native backend
bignumCheck :: Bool,
-- | Build libraries these ways.
libraryWays :: Ways,
-- | Build RTS these ways.
rtsWays :: Ways,
-- | Build dynamic GHC programs.
dynamicGhcPrograms :: Action Bool,
-- | Enable GHCi debugger.
ghciWithDebugger :: Stage -> Bool,
-- | Build profiled GHC.
ghcProfiled :: Stage -> Bool,
-- | Build GHC with the debug RTS.
ghcDebugged :: Stage -> Bool,
-- | Build GHC with debug assertions.
ghcDebugAssertions :: Stage -> Bool,
-- | Build the GHC executable against the threaded runtime system.
ghcThreaded :: Stage -> Bool,
-- | Whether to build docs and which ones
-- (haddocks, user manual, haddock manual)
ghcDocs :: Action DocTargets }
-- | A set of documentation targets
type DocTargets = Set DocTarget
-- | Documentation targets
--
-- While we can't reasonably expose settings or CLI options
-- to selectively disable, say, base's haddocks, we can offer
-- a less fine-grained choice:
--
-- - haddocks for libraries
-- - non-haddock html pages (e.g GHC's user manual)
-- - PDF documents (e.g haddock's manual)
-- - man pages (GHC's)
--
-- The main goal being to have easy ways to do away with the need
-- for e.g @sphinx-build@ or @xelatex@ and associated packages
-- while still being able to build a(n almost) complete binary
-- distribution.
