Modulebyteslice-0.2.15.0Haskell2010
This module contains functions which operate on supersets of Bytes containing ASCII-encoded text. That is, none of the functions here inspect bytes with a value greater than 127, and do not fail due to the presence of such bytes.
Perform an action on each line of the input, threading state through the computation. If you do not need to keep a state, see hForLines_.
Lines are extracted with with hGetLine, which does not document its
detection algorithm. As of writing (bytestring v0.11.1.0), lines are
delimited by a single n character (UNIX-style, as all things should be).
Perform an action on each line of the input, discarding results. To maintain a running state, see hFoldLines.

O(n) Convert ASCII letters to lowercase. This adds 0x20 to bytes in the
range [0x41,0x5A] (A-Z ⇒ a-z) and leaves all other bytes alone.
Unconditionally copies the bytes.
