Description

Duplicates a subset of the Stack ADT. It'd be nice if we could just re-use the actual ADT, but stack isn't available as a library that we can build from Hackage.

Synopsis

localDirs :: Stack -> NonEmpty FilePath
readStack :: ByteString -> IO Stack
unroll :: FilePath -> Stack -> IO Resolvers
resolve :: Maybe FilePath -> ResolverRef -> IO (Maybe FilePath, Resolver)
cache :: Text -> IO FilePath
stack2resolver :: Stack -> Resolver
new2old :: NewResolver -> Resolver
mergeResolvers :: Resolver -> Resolver -> Resolver
decode1Strict :: FromYAML a => ByteString -> Either String a

readStack :: ByteString -> IO Stack Source #

stack2resolver :: Stack -> Resolver Source #

new2old :: NewResolver -> Resolver Source #

mergeResolvers :: Resolver -> Resolver -> Resolver Source #

Merging two resolvers is straight-forward, except for handling Git deps. These need to be merged carefully, because stack.yaml may add subdirs to the repo of a resolver. Also see: https://github.com/hasufell/stack2cabal/issues/30
