[JBoss JIRA] Created: (JBRULES-1430) Improve Function feature

by longDuck dong (JIRA)

Improve Function feature ------------------------ Key: JBRULES-1430 URL: http://jira.jboss.com/jira/browse/JBRULES-1430 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: All Affects Versions: 4.0.4 Environment: all Reporter: longDuck dong Priority: Minor The current design of the Function is a bit limiting. for example, if I want to write a function to insert, update or retract facts, the current design does not support it. According to the docs http://downloads.jboss.com/drools/docs/4.0.4.17825.GA/html/ch06s04.html, functions are just helper methods. It would be more powerful if the function always passes the workingmemory to the function. This way, the functions can easily access the globals or access the rule engine. Basically, something similar to JESS funcall http://herzberg.ca.sandia.gov/docs/70/api/jess/Funcall.html. It also makes it easier for developers to encapsulate common actions in the consequence in a function and use it easily from a DSL. The pattern is well proven in CLIPS, JESS and haley. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1559) Ability to negate a constraint group

by Dirk Bergstrom (JIRA)

Ability to negate a constraint group ------------------------------------ Key: JBRULES-1559 URL: http://jira.jboss.com/jira/browse/JBRULES-1559 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Drl Parser/Builder Affects Versions: FUTURE Reporter: Dirk Bergstrom Assigned To: Mark Proctor Priority: Minor I want to write a rule that says "Find all long-eared dogs that do not have short, black hair". This seems like the simple way to do it: collect( Dog( ears=="long", not (hair=="short" && color=="black") ) But that doesn't parse. Some digging through the archives unearthed a mention of De Morgan's laws, which leads to: http://en.wikipedia.org/wiki/De_Morgan's_laws Which explains that I can instead write: collect( Dog( ears=="long", (hair!="short" || color!="black") ) Which, after some mental effort, turns out to be the right thing. However, had I not found the reference to De Morgan's Law, it would have taken me a long time to get there (if indeed I ever would have). The end result is also quite difficult to parse if you're not a logician, and thus not very user-friendly. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBRULES-1662) Tomcat Debugging of Rules

by Paul Ryan (JIRA)

Tomcat Debugging of Rules ------------------------- Key: JBRULES-1662 URL: http://jira.jboss.com/jira/browse/JBRULES-1662 Project: JBoss Drools Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Eclipse IDE Environment: Tomcat 5+ and Eclipse IDE Reporter: Paul Ryan Assigned To: Mark Proctor The ability to debug rules while running from a tomcat instance. This would be helpful for those of us that have services wrapping the rules so that we can debug into running rule sets. This feature should be capable of running its own instance of tomcat as well as attaching to a debug version of an externally running tomcat to allow for flexibility based on the users socket needs. This feature would be a huge selling point for enterprise applications of Drools. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
