Hi Joel,
I can see that it would be possible to yypush_parse for a while, and
then call yypull_parse. However, would it be possible to start calling
yypush_parse after yypull_parse returned? The loop in yypull_parse
currently looks like,
do {
yychar = YYLEX;
yystatus =
yypush_parse (yyps_local);
} while (yystatus == YYPUSH_MORE);
so I'm thinking the only point it would end is when the grammar is
finished. That is yystatus != YYPUSH_MORE.
I think it should allow the user to break out on certain circumstances?
Am I missing something?
Thanks,
Bob Rossi
