Parsing

readConfig :: IO (Config Identity)

High level convinience function to find and read ~.cabalconfig file

May throw IOException when file doesn't exist, and ParseError on parse error.

findConfig :: IO FilePath

Find the ~/.cabal/config file.

parseConfig :: FilePath -> ByteString -> Either (ParseError NonEmpty) (Config Maybe)

Parse ~/.cabal/config file.

resolveConfig :: Config Maybe -> IO (Config Identity)

Fill the default in ~/.cabal/config file.

Hackage

cfgRepoIndex :: Config Identity -> RepoName -> Maybe FilePath

Find a 01-index.tar for particular repository

hackageHaskellOrg :: RepoName

The default repository of haskell packages, https://hackage.haskell.org/.
