  1. AI_NUMERICHOST :: AddrInfoFlag

    network Network.Socket

    The HostName argument must be a numeric address in string form, and network name lookups will not be attempted.

  2. AI_NUMERICSERV :: AddrInfoFlag

    network Network.Socket

    The ServiceName argument must be a port number in string form, and service name lookups will not be attempted. (Only some platforms support this.)

  3. NI_NUMERICHOST :: NameInfoFlag

    network Network.Socket

    The name of the host is not looked up. Instead, a numeric representation of the host's address is returned. For an IPv4 address, this will be a dotted-quad string. For IPv6, it will be colon-separated hexadecimal.

  4. NI_NUMERICSERV :: NameInfoFlag

    network Network.Socket

    The name of the service is not looked up. Instead, a numeric representation of the service is returned.

  5. data PortNumber

    network Network.Socket

    Port number. Use the Num instance (i.e. use a literal) to create a PortNumber value. 

    >>> 1 :: PortNumber
1

>>> read "1" :: PortNumber
1

>>> show (12345 :: PortNumber)
"12345"

>>> 50000 < (51000 :: PortNumber)
True

>>> 50000 < (52000 :: PortNumber)
True

>>> 50000 + (10000 :: PortNumber)
60000

  6. type ProtocolNumber = CInt

    network Network.Socket

    Protocol number.

  7. alphaNum :: forall s (m :: Type -> Type) u . Stream s m Char => ParsecT s u m Char

    parsec Text.Parsec.Char

    Parses a alphabetic or numeric Unicode characters according to isAlphaNum. Returns the parsed character. Note that numeric digits outside the ASCII range (such as arabic-indic digits like e.g. "٤" or U+0664), as well as numeric characters which aren't digits, are parsed by this function but not by digit.

  8. alphaNum :: forall s (m :: Type -> Type) u . Stream s m Char => ParsecT s u m Char

    parsec Text.ParserCombinators.Parsec.Char

    Parses a alphabetic or numeric Unicode characters according to isAlphaNum. Returns the parsed character. Note that numeric digits outside the ASCII range (such as arabic-indic digits like e.g. "٤" or U+0664), as well as numeric characters which aren't digits, are parsed by this function but not by digit.

  9. enumerate :: Location -> [Location]

    doctest Test.DocTest.Internal.Location

    Create a list from a location, by repeatedly increasing the line number by one.

  10. enumFromToC :: forall (m :: Type -> Type) a i . (Monad m, Enum a, Ord a) => a -> a -> ConduitT i a m ()

    conduit Conduit

    Enumerate from a value to a final value, inclusive, via succ. This is generally more efficient than using Prelude's enumFromTo and combining with sourceList since this avoids any intermediate data structures.
