            You need to construct something to hold all of the firstname/course combinations that you want to generate averages for. In the actions of the rule you'd have to iterate over the quiz facts and generate one multifield variable containing ("Mike" "Ronald" "Lionel") and another containing ("Math" "Math" "English"). Then you'd have to iterate these lists using the indices from 1 to the length of the lists and then use the nth$ function to pull out the name and the course from each list. Then you could use the fact query functions to pull out the averages for each name/course and compute the total average.

            Rather than do all that, you could write a rule which determines all of the name/course for which an average is needed and assert that as a fact:

            CLIPS: Clear-window in CLIPSDOS.exe and tab to indent in CLIPSIDE
            Asked 2022-Feb-19 at 20:02

            With CLIPS, It's possible some of the following?? (V 6.4 for Windows)

            1 - Use a command like (clear-window) in the CLIPSDOS console for clear the console.
            2 - Use tabs for indentation in CLIPSIDE. When i press tab, cursor goes to File menu item... how to indent?

            How do people learn programming with CLIPS? I'm using a plugin for Visual Studio that helps me with the parenthesis concordance, let me use tabs to indent, and other tricks. But it has some problems, and i'm quite worried about the usability of the CLIPSDOS and CLIPSIDE interfaces to this purpose.

            Thanks in advance.

            In CLIPSDOS, you can use the command (system cls) to clear the screen. This will simply call out to DOS to execute a cls command.

            The IDEs use standard text editing classes for the CLIPS command prompt window. Tabs appear to work correctly on the macOS IDE, but not the Windows or Java Swing IDEs, so that will need to be corrected.

            While you can directly enter constructs at the command prompt, it's better to edit them in a file with your preferred text editor and then use the load command from the command prompt to load the contents of that file. The IDE supports a command history so you can use the up/down arrow keys to cycle through prior commands to avoid retyping.

            QUESTION

            Can a rules file have a dependency on other rules?
            Asked 2022-Feb-09 at 08:07

            I'm using drools rules engine for my new service. I'm looking at cleaning up the rules / making it easier to write. I was hoping to use a rules framework style of coding. I.e. I want a rules file who's sole purpose is to validate the input data (i.e. input list isn't null and contains a specific value). Then when I write new rules files I can just say import this and run the validation before all other rules.

            Also, I know I can load multiple rules file into the KieSession. Is it possible to tell it which order to run the rules files in, or which files to skip for each use case? The idea behind this is for performance. Let's say I load up an AWS lambda function with the rules service, I want to have all rules loaded already and have it run the specific one for the use case, instead of loading up a rules file for each call.

            Thanks for the help.

            You asked

            Is it possible to tell it which order to run the rules files in, or which files to skip for each use case?

            The answer is yes. The method to do this is called salience. The linked article is a good source to learn about this. This is important because salience can make it possible to change the order of execution of rules.

            Hypothetically, let say that you have a program that process transactions based on categories. So, if category == deposit, you want to add to current balance. You have another rule that if category == withdrawal you want to subtract from current balance. BUT, you want to process deposits over withdrawals. Using salience you can guarantee that the deposits rule will fire before the withdrawal rule regardless of order of transaction.

            Dependency is kind of related, but not the same. In drools, this is know as Forward or Backward Chaining depending on the order. This is all composed based on a series of facts. For example, if I was to ask a system "is my house on planet Earth?" the conclusion is reached if the following facts exist:

            1. My house is in Fort Worth
            2. Fort Worth is a city in Texas
            3. Texas is a state in the United States
            4. United States is a country on Earth

            A direct fact linking the house location to this planet is asserted based on the rules that verify the enumerated facts above. This is done using chaining. Forward or backwards is just how these are processed (top-down or bottom-up). This is in a nutshell to the best of my recollection.

            Drools: When using JPAWorkingMemoryDbLogger, the processInstanceId is always 1
            Asked 2021-Dec-17 at 09:58

            We've been executing a JBPM decision tree in memory for our call center. This works great, but we'd really like to be able to render diagrams in our BusinessCentral instance. This means we have to add JPAWorkingMemoryDbLogger so it logs stuff out to the drools tables. We're not using kie-server to execute our JBPM, but executing it in the follow code.

            What we're finding is that every process instance id is 1, whereas other things JBPM we execute via kie-server manage to get an incremented PID.

            What do we need to change in the setup of the KieSession so it it increments the process instance id?

            You're kind of going about this in a funny way. Part of the reason your rules don't work is because you're trying to put consequences into the conditional section.

            We can break down your problem into the following.

            Given:

            • a Student, who has a status and marks.

            Rule 1:

            • When status = active and marks > 65, a student is eligible for Award65.

            Rule 2:

            • When status = active and marks > 75, a student is eligible for Award75.

            This is pretty straight forward.

            So far, our rules will look like this:

            Karate Framework as a Rules Engine
            Asked 2021-Aug-11 at 07:33

            I have an api project which requires the payload to be validated against a set of rules. For this, I have written a karate feature file with all the required assertions for my incoming request json payload. The feature file then returns true or false depending upon the satisfied conditions. This mechanism is working perfectly in my local currently.

            Is this approach recommended for production use case? Will the karate framework in this format be capable of handling large volumes of requests coming in a very short span of time?

            Answered 2021-Aug-11 at 07:33

            Developer of Karate here, I really like your question because it validates what I personally believe, that Karate just makes it easy to work with JSON.

            Why I won't recommend this for production use is because Karate embeds a JS engine that can be targeted using a "script injection" attack. Karate is designed for users running "locally" and has no safeguards built-in to prevent any malicious attacks coming in via JSON payloads.

            The other question is performance, personally I am quite confident, because Karate is being used in conjunction with Gatling and some work has gone into improving performance over the years. But at the end of the day, Karate does use a JS engine in interpreted mode. So you need to run a performance test or load test yourself to validate if Karate can handle the volume you expect.

            Maybe you can contribute to Karate to address both the above concerns !

            The expectation for the RulesEngine(string[], ILogger, ReSettings) constructor is that each element of the string array is a complete JSON object. In your case, you've provided just a single line per array element.

            Given that your text file already contains a collection of rules, you should deserialize it yourself, and pass the deserialized collection into the constructor accepting a WorkflowRules[]:

            You don't really remove it, you just overwrite it. You can create a new draft, lock it, and deploy it on top of the existing one.

            Also note that you can't have an empty policy.
