Unique ID to Clipboard for Workflowy (or whatever), OSX

uniqueid

#!/usr/bin/env ruby
# uiqueid generates a 4 character unique ID and puts it in the clipboard

# configurable variables
prefix = "WF-"
totalChars = 4
startPoint = 97   # use 65 for upper, 97 for lower

def pbcopy(input)
 str = input.to_s
 IO.popen('pbcopy', 'w') { |f| f << str }
 str
end

def pbpaste
 `pbpaste`
end

if __FILE__ == $0
	thing = (0...totalChars).map { (startPoint + rand(26)).chr }.join
        pbcopy "#{prefix}#{thing}"
end

This is pseudo-unique. Chances of collision are 26^totalChars, so in this example it's 1 in 456,976.
