Can Detekt be used to create an annotation to enforce parameters in DSLs?

[elect86]

As titled, I'm looking for a non-android solution to this, which uses an Android linter library:

@DSLint
class Person {

    @set:DSLMandatory
    var name: String
}

I hope this might be possible in compile time through the definition of a custom config definition or something similar, but I'm not familiar with static analyzers, so this is all speculation

Hey @elect86

As titled, I'm looking for a non-android solution to this, which uses an Android linter library:

That's totally doable. You can create your custom rule using this template https://github.com/detekt/detekt-custom-rule-template

And inspect the DSL calls + verify that certain parameters are declared or not. It can be totally custom (i.e. you hardcode the business logic inside the body of the rule) or you can provide some degree of configurability via external params or so.

Ok so, I pushed (I modified one of the tests):

        annotation class DslMandatory(text: String)
        class Person(
            @DslMandatory
            var name: String,
            var age: Int)
        fun person(configure: Person.() -> Unit) = Person().configure()
        fun main() {
            person { 
            }
        }

My first idea is to work around visitLambdaExpression and then from there detect if there is a receiver and if that receiver has one the fields annotated by DslMandatory

But I have no idea how to do this.. any idea?

For future reference: I pushed a draft version of the rule here elect86/DslMandatory@189e8b6
