There is an issue with the file sql-2003-2.marpa in proof_of_conceot. In
line 6 it says:
<SQL_Start_many> ::= <SQL_Start>+ rank => 0
instead of what seems that it should have been
<SQL_Start_many> ::= <SQL_Start_Sequence>+ rank => 0
That generated the error:
Uncaught exception from user code:
Could not resolve rule action named 'nonTerminalSemantic'
Rule was SQL_Start_many ::= SQL_Start +
Could not fully qualify "nonTerminalSemantic": no resolve package
When fixed it, I've got
Uncaught exception from user code:
Unproductive start symbol
Marpa::R2 exception at
C:\projects\MarpaX-Languages-SQL-AST-master\tests
ql.pl line 9.
my $g = Marpa::R2::Scanless::G->new({source => \$G});
Thanks
ZA
