Modulehaskeline-0.8.2.1Haskell98
System.Console.Haskeline.History
This module provides a low-level API to the line history stored in the InputT monad transformer.
For most application, it should suffice to instead use the following Settings flags:
autoAddHistory: add nonblank lines to the command history (True by default).historyFile: read/write the history to a file before and after the line input session.
If you do want custom history behavior, you may need to disable the above default setting(s).
