[Pythonmac-SIG] Problems with grammar for dparser

[Joachim Mårtensson]

Hello, I am playing around a little bit with dparser, and I thought that 
maybe someone on this list can help me out (There does not seem to be a 
dparser list, atleast not an active one). I am total n00b to parsers so 
this might be very easy. I want a parser that can parse both these lines 
(What I am looking to construct is a parser of a _very_ limited subset 
of objective-c).

[[self _rowsForAddingContentObject:content] retain]
NSArray *contentRowArray
This is what I have so far.
from dparser import Parser
def d_objcmsg(t):
  'objcmsg: "\[" (objcmsg|var) msg "\]" '
def d_varDef(t):
  'varDef: classname "\*" var'
def d_classname(t):
  'classname: "[A-Z][A-Za-z_0-9]*"'
def d_var(t):
  'var: "[a-z_][A-Za-z_0-9]*" '
def d_msg(t):
  'msg: (msgWithArg|"[a-z_][A-Za-z_0-9]*")'
def d_msgWithArg(t):
  'msgWithArg: "[a-z_][A-Za-z_0-9]*" ":" (var|objcmsg)'
this makes the "[[self _rowsForAddingContentObject:content] retain]" 
line pass, however I get a syntax error on the other one. Switching the 
placing of d_obcmsg and d_varDef makes the other line pass, but then the 
first fail with a syntax error. I want both of the lines to pass. Anyone 
have any ideas?

Joachim
