how can I detect newline ("\n")?

[jarodtang]

Hi there,

I craft some grammar like
'''
Parser term() => ref0(character).plus().flatten().trim();

///
Parser character() =>
ref0(characterNormal) | ref0(characterUnicode) | ref0(characterEscape);
Parser characterNormal() => pattern('^ ,.{}[]|=#*/_\r\n\');
Parser characterEscape() => char('\');
Parser characterUnicode() => string('\u') & pattern('0-9A-Fa-f').times(4);
''

and try parse something like "a\nb", where I try to detect \n as new line, but the parser always ignore the '\n', how can I handle it?

Regards,
Jarod

Note that .trim() consumes all whitespace (including new-lines), so that might be a problem?

It's the problem! Thanks!
