Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-compiler-DSL

Reporter: Barry Kaplan
Assignee: Mark Proctor
Consider the following:
declare Foo
end : String
end
rule "foo" dialect "java"
when
then
foo = new Foo()
e = foo.end()
end
The compiler fails with the following error: [xx,yy]: [ERR 102] Line xx:yy mismatched
input '('
If the rule is changed to (ie, remove the parens on the 'end')
rule "foo" dialect "java"
when
then
foo = new Foo()
e = foo.end
end
The compiler error is: [0,-1]: [ERR 101] Line 0:-1 no viable alternative at input
'<eof>'

---------------------------------------
end is currently a "hard" keyword for the antlr parser, so cannot be used as a
field name.

----------------------------------------
Documentation is here:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht...
"end" is a soft keyword, but it is the delimiter for a rules consequence, so it
can't be used "as-is" inside a rule consequence. To do that you need to
escape it, as demonstrated in the docs, using back quotes:
then
foo = new Foo()
e = foo.`end`
end

I'm not seeing this behavior:
with this
update(entryPoints["downtime"].getFactHandle(downtime),
downtime.`end`)
I get
java.lang.RuntimeException: [41,23]: [ERR 102] Line 41:23 mismatched input ')'
with this
update(entryPoints["downtime"].getFactHandle(downtime),
downtime.`end`())
I get
java.lang.RuntimeException: [41,23]: [ERR 102] Line 41:23 mismatched input '('
----
where:
case class DowntimeInterval(deviceId: String, interval: Interval,
classification: Option[DowntimeClassification] = None,
id: String = ObjectId.get.toString)
extends DeviceEvent with Logging {
def this(deviceId: String) = this(deviceId, fromNow)
debug("downtime: started now="+interval.start)
def end = {
debug("downtime: ended interval="+interval)
this.copy(interval = this.interval.start to now)
}
def endd = end // alias for drools
def classify(classification: DowntimeClassification): DowntimeInterval = {
debug("classfied as: "+classification)
copy(classification = Some(classification))
}
}
Using the 'endd' method does work:
update(entryPoints["downtime"].getFactHandle(downtime),
downtime.endd)
