Hi,
Suppose I want to recognize each pattern 'okko' in a random string of
characters. Some examples:
aaaaaoookoooookkooooaaa -> should yield one match of 'okko'
aaaokkookko -> should yield two matches of 'okko'
Here is a grammar that won't work ;o)
grammar test;
start : .* pattern .*;
pattern : T1 T2 T2 T1;
T1 : 'o';
T2 : 'k';
No matter what grammar I try. I can't get it to work... how hard can it be?
Thanks for any input you may provide,
Bill
