Lua code help (stuf text)

[Rusken]

Evening, i got this custom lua code from a fella over at mmo a couple of months back and what it does is that it shortens name like "Raider's Training Dummy" in to "R.T.Dummy".
What i need help with is to change the code so it still does what it does but i want it to look like this ->

"R.T.Dummy | 100", 100 being perchp and i want it to be colored by "hpthreshold", the name and the "|" should be white.

So, is this possible and is there any kind soul here with the knowledge on how to do this that could give me a hand?
Thanks in advance.
