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 ) {
}

I was wandering through the documentation and Google, not able to find
understood able code which helps me to generate internal DRL out of DSL and
DSLR. Because this helps me to clearly find out the problem with my DSL and
DSLR.

Please post the code which reads the DSL & DSLR from classpath and spits out
DRL.


Thanks in advance.
