[coding] Right click to rename as Android Resource

I wanted a context menu hook that would rename any file to one that is compatible with the android resource filename format.  I tried to get a craigslist programmer to do it, however craigslist programmers are whiny, insecure bitches.  And...I ended up doing it myself to prove a point to one of them.  The code looks like shit and has a few bugs on it, but I've already wasted enough time.  I'm pasting it here in case any of you do Android programming.















require 'win32/registry.rb'

#
# To Install:
#
# 1. r-click on command window, run as administrator
# 2. ruby [this script name] --register

def registerContextMenu(myPath, rubyLoc)
    #http://www.howtogeek.com/107965/how-to-add-any-application-shortcut-to-windows-explorers-context-menu/
   
    keyParent = "*\\shell\\"
    myPath = rubyLoc + " " + myPath + " %1"
    key = keyParent + "Rename as Android Resource"

    begin
    reg = Win32::Registry::HKEY_CLASSES_ROOT.create(key, Win32::Registry::KEY_WRITE)
    commandReg = Win32::Registry::HKEY_CLASSES_ROOT.create(key + "\\command", Win32::Registry::KEY_WRITE)
    commandReg.write_s(nil, myPath)
   
    rescue Win32::Registry::Error
        puts "Access is denied; run command line as Administrator"
        exit
    end

end


def fileToAndroid(name)
     a = name.reverse.split(".", 2).reverse
     base = filePartToAndroid(a[0].reverse, dupeBuster())
     ext = (a.length > 1) ? filePartToAndroid(a[1].reverse, "") : ""
     filename = (base + "." + ext).gsub(/[\.]$/,'')
    if File.exist?(filename)
        filename = base + dupeBuster()
    end   
    return filename
   
end

def filePartToAndroid(name, default)
    name = name.gsub(/[-\. !@#$%^&*(),]/,'_').split(/_+/).join("_").gsub(/^_+/,'')
    return ((name.empty?) ? default : name)
end


def dupeBuster()
    count = Dir['**/*'].count { |file| File.file?(file) }
    return count.to_s(16)
end


def renameToAndroid(filename)

    File.rename(filename, File.dirname(filename) + "/" + fileToAndroid(File.basename(filename)));
end

begin
    if ARGV[0].nil?
        puts "at least one argument expected.  use --register to register in context menu"
       
        sleep(2)
        exit
    elsif ARGV[0] === "--register"

        rubyLoc = "C:\\Ruby193\\bin\\ruby.exe"
        registerContextMenu(File.expand_path(File.dirname(__FILE__)) + "/" + $0, rubyLoc)
       
        sleep(2)
    else
        if !File.exists?(ARGV[0])
            puts "file does not exist"
           
            sleep(2)
            exit
        end
       
        renameToAndroid(ARGV[0]) #"--test-a-b-.-c-"
       
    end

rescue => msg 
    puts "error encountered: " + msg.to_s
    puts msg.backtrace
    sleep(10)
end
