This module is intended to allow the launch of the same application but changing the parameters using the user response. For example, when you want to open a image in gimp program, you can open gimp and then use the File Menu to open the image or you can use this module to select the image in the command line.

We use Prompt to get the user command line. This also allow to autoexpand the names of the files when we are writing the command line.

First, you need to import necessary modules. Prompt is used to get the promp configuration and the AppLauncher module itself.

 import XMonad.Prompt
 import XMonad.Prompt.AppLauncher as AL

Then you can add the bindings to the applications.
