multiple rules in rule descriptor

[Siktik]

hey,

i want to give a customer the possibility to write a .yml file that i read from for the programm. I was wondering if it is possible to have multiple rules in a rule descriptor .yml. In the examples there is always only one rule, if there is a way to read more rules i would really want to know how this could be achieved. Thank you in advance!

Of course it can be supported, you can take a look at this implementation class.

https://github.com/j-easy/easy-rules/blob/master/easy-rules-support/src/main/java/org/jeasy/rules/support/reader/YamlRuleDefinitionReader.java

Finally, load them when your app started.

rules:

• name: "weather rule" description: "if it rains then take an umbrella" condition: "rain == true" actions:

  • "System.out.println(\"It rains, take an umbrella!\");"

• name: "temperature rule" description: "if the temperature is below 20 then wear a jacket" condition: "temp < 20" actions:

  • "System.out.println(\"It is cold, wear a jacket!\");"
