ply yacc lineno not working?

[Laszlo Nagy]

This is a fragment from my yacc file:


import ply.yacc as yacc
from lex import tokens
from ast import *

def p_msd(p):
    r"""msd : SCHEMA WORD LBRACE defs RBRACE """
    p[0] = MSDSchema(p[2])   
    print p.lineno(5) # Line number of the right brace
    p[0].items = p[4]


Here is a test input: """

schema TestSchema {
    field name : varchar { required; size 100; }
}

"""


My program prints out 1. No matter what I do, YaccProduction.lineno(n) 
returns 1 for every possible n between 0 and 5. What am I doing wrong? 
Can it be a problem if I use this in my lexer:

# Whitespace is mostly ignored, except inside quoted words.
def t_ws(t):
    r'[\n\r\t ]+'
    # We do not return anything so this will be ignored.


If so, how can I easily ignore newlines while preserving the line number 
for yacc.parse ?

Thanks,
