Sure.  You need to use Happy's %monad feature, the documentation
describes how to turn parse errors into something you can handle in the
program:

handling errors in Happy

2002-04-02 Thread Andre W B Furtado 

Is it possible to get the result of function happyError, in the main module
of my program (which imports the module generated by Happy)?

Thanks a lot,
