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).
|Add a line to the history unless it matches the previously recorded line.
|Add a line to the history, and remove all previous entries which are the
same as it.
|The input lines stored in the history (newest first)
|Reads the line input history from the given file. Returns
emptyHistory if the file does not exist or could not be read.
|Writes the line history to the given file. If there is an
error when writing the file, it will be ignored.
|Limit the number of lines stored in the history.
|The maximum number of lines stored in the history. If Nothing, the history storage is unlimited.
