Description
A module for setting up simple confirmation prompts for keybindings.
Synopsis
- confirmPrompt :: XPConfig -> String -> X () -> X ()
- mkComplFunFromList :: XPConfig -> [String] -> String -> IO [String]
- mkXPrompt :: XPrompt p => p -> XPConfig -> ComplFunction -> (String -> X ()) -> X ()
- data XPConfig
- class XPrompt t where
- showXPrompt :: t -> String
- data EnterPrompt
Documentation
confirmPrompt :: XPConfig -> String -> X () -> X () Source #
Prompt the user to confirm a given action. We offer no completion and simply ask to confirm (ENTER) or cancel (ESCAPE). The actual key handling is done by mkXPrompt.
Usage
This module makes it easy to add a confirmation prompt for specific
actions. Instead of just running the action, a simple confirmation
prompt will be created using Prompt primitives. The action
will then run normally if the user confirms.
mkComplFunFromList :: XPConfig -> [String] -> String -> IO [String] Source #
This function takes a list of possible completions and returns a
completions function to be used with mkXPrompt
mkXPrompt :: XPrompt p => p -> XPConfig -> ComplFunction -> (String -> X ()) -> X () Source #
Creates a prompt given:
- a prompt type, instance of the
XPromptclass. - a prompt configuration (
defcan be used as a starting point) - a completion function (
mkComplFunFromListcan be used to create a completions function given a list of possible completions) - an action to be run: the action must take a string and return
X()
class XPrompt t where Source #
A class for an abstract prompt. In order for your data type to be a valid prompt you _must_ make it an instance of this class.
The minimal complete definition is just showXPrompt, i.e. the name
of the prompt. This string will be displayed in the command line
window (before the cursor).
As an example of a complete XPrompt instance definition, we can
look at the Shell prompt from
XMonad.Prompt.Shell:
data Shell = Shell
instance XPrompt Shell where
showXPrompt Shell = "Run: "Methods
showXPrompt :: t -> String Source #
This method is used to print the string to be displayed in the command line window.
Instances
Use case: confirming exit
This should be used something like this:
... , ((modm , xK_l), confirmPrompt def "exit" $ io (exitWith ExitSuccess)) ...
data EnterPrompt Source #
Customized XPrompt prompt that will ask to confirm the given string
