Documentation

readHieFile :: NameCache -> FilePath -> IO HieFileResult Source #

Read a HieFile from a FilePath. Can use an existing NameCache.

readHieFileWithVersion :: (HieHeader -> Bool) -> NameCache -> FilePath -> IO (Either HieHeader HieFileResult) Source #

Read a HieFile from a FilePath. Can use an existing NameCache. Allows you to specify which versions of hieFile to attempt to read. Left case returns the failing header versions.

type HieHeader = (Integer, ByteString) Source #

writeHieFile :: FilePath -> HieFile -> IO () Source #

Write a HieFile to the given FilePath, with a proper header and symbol tables for Names and FastStrings

data HieName Source #

Name's get converted into HieName's before being written into .hie files. See toHieName and fromHieName for logic on how to convert between these two types.
