I finally integrated my language in a Visual C++ project. My last problem is
that, while everything went right while working on a single dos executable
(representing the language), I got weird mood while using it under my app.
After parsing something, sometimes happen that new inputs are not
recognized, while if I close the app and start it again, the parsing finish
well. I think I forgot something, but I don't know what!
Before calling yyparse() i do the following:
yy_delete_buffer(YY_CURRENT_BUFFER); // delete previous buffer
// reset all data structures used in rule actions
my_buffer_state=yy_scan_string(input.c_str()); // load the input to
in Flex, I use the following to reset to initial start condition
#define YY_USER_INIT BEGIN(INITIAL)
What else should I do to be sure everything could work well?
