getContents -package:text

The getContents operation returns all user input as a single string, which is read lazily as it is needed. getContents is implemented as hGetContents stdin. This operation may fail with the same errors as hGetContents.

Examples

>>> getContents >>= putStr
> aaabbbccc :D
aaabbbccc :D
> I hope you have a great day
I hope you have a great day
> ^D
>>> getContents >>= print . length
> abc
> <3
> def ^D

getContents. Read stdin strictly. Equivalent to hGetContents stdin The Handle is closed after the contents have been read.
getContents. Equivalent to hGetContents stdin. Will read lazily
Receive data from the socket. The socket must be in a connected state. Data is received on demand, in chunks; each chunk will be sized to reflect the amount of data received by individual recv calls. All remaining data from the socket is consumed. When there is no more data to be received, the receiving side of the socket is shut down. If there is an error and an exception is thrown, the socket is not shut down.

Read all user input on stdin as a single string
The getContents' operation returns all user input as a single string, which is fully read before being returned getContents' is implemented as hGetContents' stdin. This operation may fail with the same errors as hGetContents'.

Examples

>>> getContents' >>= putStr
> aaabbbccc :D
> I hope you have a great day
aaabbbccc :D
I hope you have a great day
>>> getContents' >>= print . length
> abc
> <3

Computation hGetContents hdl returns the list of characters corresponding to the unread portion of the channel or file managed by hdl, which is put into an intermediate state, semi-closed. In this state, hdl is effectively closed, but items are read from hdl on demand and accumulated in a special list returned by hGetContents hdl. Any operation that fails because a handle is closed, also fails if a handle is semi-closed. The only exception is hClose. A semi-closed handle becomes closed:
  • if hClose is applied to it;
  • if an I/O error occurs when reading an item from the handle;
  • or once the entire contents of the handle has been read.
Once a semi-closed handle becomes closed, the contents of the associated list becomes fixed. The contents of this final list is only partially specified: it will contain at least all the items of the stream that were evaluated prior to the handle becoming closed. Any I/O errors encountered while a handle is semi-closed are simply discarded. This operation may fail with:
