How to remove a starting newline?

How to remove a starting newline?

How would I remove a starting newline from a string, if it exists?  Since I created the newlines using "\n" I'm not sure exactly how to check for it and then to exclude it in the revised string.

FYI I'm building a string by concatenating multiple values and starting each with a newline.  Those with no value are skipped, but the end result can be a starting newline.

The logic would be something like this, but I don't know the deluge syntax or best practice, I'd think it involves startsWith, Length, and substrings:
  • If the string starts with a newline
  • the string = the entire right side of the string starting just after that newline

(Note that I don't want to remove all newlines.  Just any starting one.)

Many thanks!
