getLine

getLine :: IO String
base Prelude System.IO, ghc-internal GHC.Internal.System.IO
Read a line from the standard input device. getLine is implemented as hGetLine stdin. This operation may fail with the same errors as hGetLine.

Examples

>>> getLine
> Hello World!
"Hello World!"

>>> getLine
>
""
getLine :: IO ByteString
bytestring Data.ByteString
Deprecated: Deprecated since bytestring-0.12. Use getLine instead. (Functions that rely on ASCII encodings belong in Data.ByteString.Char8)
getLine :: IO ByteString
bytestring Data.ByteString.Char8, rawfilepath Data.ByteString.RawFilePath
Read a line from stdin.
getLine :: IO Text
text Data.Text.IO Data.Text.Lazy.IO, protolude Protolude
Read a single line of user input from stdin.
getLine :: IO Text
text Data.Text.IO.Utf8
Read a single line of user input from stdin.
