idleState function
This is the default state. It routes to the appropriate state for further handling.
Implementation
Function? idleState(Lexer lexer) {
String chr = lexer.peek();
if (chr == Token.EOF) {
return null;
}
if (isWhitespace(chr) || isLineTerminator(chr)) {
lexer.next();
lexer.ignore();
return idleState;
}
switch (chr) {
case "@":
return dateTimeState;
case "#":
return metaKeyState;
case "*":
return noteState;
default:
return valueState;
}
}
