trim.applescript

on trim(theseCharacters, someText)
  -- default values (all whitespace)
  if theseCharacters is true then set theseCharacters to {" ", tab, ASCII character 10, return, ASCII character 0}
  
  repeat until first character of someText is not in theseCharacters
    set someText to text 2 thru -1 of someText
  end repeat
  
  repeat until last character of someText is not in theseCharacters
    set someText to text 1 thru -2 of someText
  end repeat
  
  return someText
end trim

Code fails when calling with a non empty string trim(true, "") of non-string trim(true,123).

I fixed it in my fork, but no idea how to send a merge request...
