#!/usr/bin/env nush

; Useful script for when you have a rotating background on Mac OS X

; this script will tell you which image is currently being displayed.

; If you add -rm when calling the command then it will provide you with

; prompt to let you delete the background.

;

; Installation:

;  Copy this into something like ~/bin/current_background and then

;  $ chmod 750 ~/bin/current_background

;  then use :D

;

; Bugs:

;  1. When prompting for user input I can't seem to flush stdout manually

;     so I have to print a new line character in order to show the prompt.

;

 
(set processInfo (NSProcessInfo processInfo))

(set args (processInfo arguments))

 
(if (and (eq (args count) 3) (eq (args objectAtIndex:2) "-rm"))

    (set shouldOfferToRemove t)

    (else (set shouldOfferToRemove nil)))

 
;; Get the dictionary

(set plist ("~/Library/Preferences/com.apple.desktop.plist" stringByExpandingTildeInPath))

(set prefs (NSDictionary dictionaryWithContentsOfFile:plist))

 
;; Drill down to the dictionary key we care about

(set default ((prefs valueForKey:"Background") valueForKey:"default"))

 
;; Extract the fields we need

(set changePath (default valueForKey:"ChangePath"))

(set currentImage (default valueForKey:"LastName"))

 
;; Print the information

(puts "Current desktop image is #{currentImage}")

 
;; Offer to delete

(if (eq t shouldOfferToRemove)

    (print "Are you sure you want to delete #{currentImage} [y/N]: \n")

    (set input (((NSString alloc)

        initWithData:((NSFileHandle fileHandleWithStandardInput) availableData)

        encoding:NSUTF8StringEncoding)

            stringByTrimmingCharactersInSet:

                (NSCharacterSet whitespaceAndNewlineCharacterSet)))

    (if (or (input isEqualToString:"y") (input isEqualToString:"Y"))

        (set fm (NSFileManager defaultManager))

        (set path (changePath stringByAppendingPathComponent:currentImage))

        (if (fm removeFileAtPath:path handler:nil)

            (puts "Background #{currentImage} has been deleted")

            (else (puts "Background #{currentImage} could not be deleted")))

        (else

            (puts "Background #{currentImage} has not been deleted"))))
