[antlr-interest] Newbie question: has anyone been able to build the PL/SQL Grammar?

[Bill Boese]

Loring, Terence:

Thanks, I was able to build it deleting the line below but there are a
tremendous number of warnings regarding ambiguities.

>> Did you change it to extend TreeParser not Parser?

Nope, the version posted on the site extends TreeParser as below, my comment
only added.

+++++++++++++++++++++++++++++++++++++++++++++++++++++

class PLSqlTreeWalker extends TreeParser;

options {
    exportVocab = PLSql;
//    k = 4;
    buildAST = true;
}

+++++++++++++++++++++++++++++++++++++++++++++++++++++

Thanks for your help!

- Bill

Bill--

Just delete that line.  ANTLR 2 treewalkers are effectively k=1.
