How to completely exit the engine execution?

[eduard-nomi]

Is there a way to stop execution from the rule?
Not Retract + Complete but immediately exit without further execution when a rule matched.
It's fine that when parts executed, I just don't need evaluation of next rules.
Is it possible to do?

rule Stop "stop"  salience 10 {
when <something>
then 
     Result = "completed with errors";
     Stop();
}

rule Next "next, not executed" {
...
}

Function Complete() will stop the engine execution loop and thus stops grule.

https://github.com/hyperjumptech/grule-rule-engine/blob/master/docs/en/Function_en.md#complete

On this line (

grule-rule-engine/engine/GruleEngine.go

Line 208 in 6cbdf38

if dataCtx.IsComplete() {

) you can see that a condition check on the data context IsComplete() method will break the engine loop and thus finishing the engine execution.

As you can see in this line, This built-in function calls the datacontext's Complete() function, which latter checked by the engine loop.

grule-rule-engine/ast/BuiltInFunctions.go

Line 46 in 6cbdf38

func (gf *BuiltInFunctions) Complete() {

So,

then
    Complete();

will stop the engine execution.

Thanks for quick answer. As I understand from the doc Complete will stop current loop only and start again evaluating all rules from the start?
Complete will cause the engine to stop processing further rules in its current cycle.
If it's correct my question is how to stop the engine completely and prevent further processing.

Looking back to the source code, the Complete() function will indeed stop the engine execution. There won't be any further evaluation loop. It stop and exit the Execute function.
