What is the pattern to match a newline character in a multi-line string in ASL

I want to split the string line by line.  The problem is I cannot determine what the line delimiter is.  Also, a related question, what is the character group that matches eol?  I could not locate either of these answers in the ASL documentation.  If I have missed it, please point me to it.  Thanks in advance.

See my example code below.  Take NOTE to the line with the comment “// NEED PROPER PATTERN”

lines = list();

PARSE_MULTILINE_VAR(s){

    input=s;

    /* == Example input ==

    //do not collect leading whitespace

    rep(any(" \t\r\n"))?

    //get everything except the line terminator

    currentLine:rep(notany("\n"))  // NEED PROPER PATTERN

    //rest of the string.

    remainingLines:rep(char)? ..eol

} do {

    lines += currentLine;

    if (remainingLines != "") {

          PARSE_MULTILINE_VAR(remainingLines);

    }

}
