Petr Široký updated DROOLS-242:
-------------------------------
Description:
To get the DRL generated from decision table one has to currently use following code:
{code}
File dtable = new File("../resources/dtable.xls");
KieResources kieResources = KieServices.Factory.get().getResources();
Resource dtableResource = kieResources.newFileSystemResource(dtable);
SpreadsheetCompiler compiler = new SpreadsheetCompiler();
String drl = compiler.compile(dtableResource.getInputStream(), InputType.XLS);
{code}
It would be nice to have this functionality out-of-the-box, similarly like
'drools.dump.dir' which is used to dump the Java classes generated from DRL.
Looking at how the options are being used I see basically three possible solutions here (I
maybe missing some other options):
- get the value of `drools.dump.dir` manually using the ChainedProperties. I think this
is not good idea as it is duplicating the code.
- add this config. option into DecisionTableConfiguration. This would prevent the
backwards comptibility issues when changing the DecisionTableProvider interface, but I am
not entirely sure it is the right place for this kind of config.
- pass the entire KnowledgeBuilderConfiguration object into
DecisionTableProvider.loadFromInputStream(). This seems like the best option from the
clean-code point of view, but it would mean that the DecisionTableProvider interface would
have to altered.

Add out-of-the-box possibility to dump DRL created from decision
