UserPreferences

User preferences

Haskeline's user interface may be customized by editing a ~/.haskeline file.

Each line of a .haskeline file sets one preference field; field names are case insensitive and unparseable lines are ignored. For example:

editMode: Vi
completionType: MenuCompletion
maxhistorysize: Just 40

field name	values	default value
bellStyle	`NoBell \| VisualBell \| AudibleBell`	`AudibleBell`
maxHistorySize	`Maybe Int`	`Just 100`
editMode	`Vi \| Emacs`	`Emacs`
completionType	`ListCompletion \| MenuCompletion`	`ListCompletion`
completionPaging	`Bool`	`True`
	When listing completion alternatives, only display one screen of possibilities at a time.
completionPromptLimit	`Maybe Int`	`Just 100`
	If more than this number of completion possibilities are found, ask before listing them.
listCompletionsImmediately	`Bool`	`True`
	If `False`, completions with multiple possibilities will ring the bell and only display them if the user presses `TAB` again.
historyDuplicates	`AlwaysAdd \| IgnoreConsecutive \| IgnoreAll`	`AlwaysAdd`
	If this is set to `IgnoreConsecutive`, a line will not be added to the history if it matches the previous entry. If it is set to `IgnoreAll`, all previous entries matching the current line will be removed.
	This preference is available in haskeline>=0.6.2.
