1. read_sections :: String -> Either GZipError [Section]

   MissingH	System.FileArchive.GZip

   Read all sections.

2. readBinaryFile :: FilePath -> IO String

   MissingH	System.IO.Binary

   Like the built-in readFile, but opens the file in binary instead of text mode.

3. readState :: ArrowReader r a => a b r

   arrows	Control.Arrow.Operations

   Obtain the current value of the state.

4. readStore :: Store a -> IO a

   foreign-store	Foreign.Store

   Read from the store. If the store has been deleted or is unallocated, this will throw an exception. Not thread-safe.

5. readDot :: ParseDotRepr dg n => IO (dg n)

   graphviz	Data.GraphViz.Commands.IO

   Read in and parse a DotRepr value from stdin.

6. readDotFile :: ParseDotRepr dg n => FilePath -> IO (dg n)

   graphviz	Data.GraphViz.Commands.IO

   Read in and parse a DotRepr value from a file.

7. readJsonFile :: FromJSON a => FilePath -> IO a

   hledger-lib	Hledger.Data.Json

   Read a JSON file and decode it to the target type, or raise an error if we can't. Eg: readJsonFile "a.json" :: IO Transaction

8. readJournal :: InputOpts -> Maybe FilePath -> Handle -> ExceptT String IO Journal

   hledger-lib	Hledger.Read

   readJournal iopts mfile txt
   

   Read a Journal from some handle, with strict checks if enabled, or return an error message. The reader (data format) is chosen based on, in this order:
   • a reader name provided in iopts
   • a reader prefix in the mfile path
   • a file extension in mfile
   If none of these is available, or if the reader name is unrecognised, the journal reader is used. If a file path is not provided, "-" is assumed (and may appear in error messages, files output etc, where it will be a slight lie: it will mean "not from a file", not necessarily "from standard input".

9. readJournal' :: Handle -> IO Journal

   hledger-lib	Hledger.Read

   An easy version of readJournal which assumes default options, and fails in the IO monad.

10. readJournal'' :: Text -> IO Journal

    hledger-lib	Hledger.Read

    An even easier version of readJournal' which takes a Text instead of a Handle.
