[Cocci] please help me with a "repetition"

[Robert Larice]

Hello,

  probably a stupid question,
  I'm failing to match something like this

+  int newvar;
   i++; i++; ... any sequence of only "i++";
+  buckbear(42);

  I don't succeed to express this "maximum length repetition"
    in the mids of those two insertions.

Best Regards,
  Robert

It's not completely straightforward.  You could try:

@r1@
position p;
@@

i++;
i++;@p

@@
position p != r1.p;
@@

+ int newvar;
i++;@p

@r2@
position p;
@@

i++;@p
i++;

@@
position p != r2.p;
@@

i++;@p
+ buckbear(42);

Thank You very much,

  your suggestion works perfectly well in my actual task.

  I was trying something different,
  very aproximately something like:
      ... when != i++;
    + int newvar;
      i++;
  and didn't get anywhere.

Thanks !
  Robert

This should work for the first bunch of i++;'s, but not if there are
several of them.
