String-prefix resulted a boolean output so, I thought of using conditionals.
Following is the line I added to  “handle-string” procedure

/(if (string-prefix? "starting phase" str) (colorized-display str
'(GREEN)) (display str target-port) ))

Do I need to write multiple definitions for each expression?

'("^starting phase.*"
    "^phase .* succeeded.*"
    "^phase .* failed.*")

I dint find this example in procedures, may I overlooked somewhere I
recheck it.

Thanks!
