[rules-users] How to generate DRL out of DSL and DSLR?

[Wolfgang Laun]

There is no "stable" API for obtaining the generated DRL. 5.2.0 introduces
several debug options (see the Expert documentation), and one of them
displays the generated DRL.

For earlier version, you can use:

import org.drools.lang.dsl.DefaultExpander;
import org.drools.lang.dsl.DSLTokenizedMappingFile;

DSLTokenizedMappingFile mapfile = new DSLTokenizedMappingFile();
DefaultExpander expander = new DefaultExpander();
Reader dslReader = ...;
Reader dslrReader = ...;
String drl;

try {
     mapfile.parseAndLoad( dslReader );
     expander.addDSLMapping( mapfile.getMapping() );
     drl = expander.expand( dslrReader );
} catch ( IOException e ) {
}
