Parsing

readConfig :: IO (Config Identity) Source #

High level convenience function to find and read ~/.cabal/config file

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

findConfig :: IO FilePath Source #

Find the ~/.cabal/config file.

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

Parse ~/.cabal/config file.

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

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

Hackage

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

Find a 01-index.tar for particular repository

hackageHaskellOrg :: RepoName Source #

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