Ability to remove rules by name

See original GitHub issue

I’m building a service using this engine. The users are able to add and remove rules whenever they want. I’m having troubles on the removal process.

Every time a user adds a rule, I create a new rule using let rule = new engine.Rule(options). With that rule I do two things:

1.- Save the JSON to the filesystem, so every time I need to reload the service I could recreate the rules. 2.- Add the rule to then engine.

This works great. The problem that I have is when I try to remove a rule. For that process the user gives me the name of the rule an I do the following:

1.- Find in the filesystem the .json file that correspond to the name the user gives me. 2.- Create a json object from that file: let ruleFromJson = JSON.parse(fs.readFileSync(file, { encoding: 'UTF-8' })) 3.- Create a Rule from that object: let rule = new engine.Rule(ruleFromJson); 4.- Remove the rule: engine.removeRule(rule);

After doing that if I run the engine passing a fact that match the deleted rule, the engine still throw onSuccess with that rule.

What I’m doing wrong?

@CacheControl , you’re right. The engine method removeRule() return false. As you do in the quick fix I manually remove the rule. We’ll wait until this feature to come out. Thanks!
