I’m trying to generate Dokka documentation for an Android project with custom Views, and the supertype’s declarations being dumped into the docs make them completely unusable at the moment 😞 View and ViewGroup have their own documentation on the Android Developer website, there’s no need to show their hundreds of methods in our docs. Our custom methods are essentially impossible to find this way.

I found an already open issue for this with no responses https://github.com/Kotlin/dokka/issues/1501

Any chance that this will be addressed soon, or is there any workaround to this problem?

If you use the development version, there is an option to have inherited functions in a separate tab: separateInheritedMembers that might help for now.
See here for documentation. Not sure in which release that will be.

[zsmb]

That would actually be really helpful - what do I need to do to get on the dev version?

[zsmb]

Or is that unpublished, and I’d have to build it myself?

[Lukas K-G]

you need to add

repositories {
    maven {
        url  "<https://dl.bintray.com/kotlin/kotlin-dev>" 
    }
}

to your maven repositories.

[Lukas K-G]

Then you can simply do e.g.

implementation 'org.jetbrains.dokka:all-modules-page-plugin:1.4.20.2-dev-60'

Actually I just tried that and did not get it to work but I had that working once. Let me have another quick look.

[zsmb]

I was gonna ask how to set this up, pulled in this version, added this config

dokkaHtml.configure {
    dokkaSourceSets {
        configureEach {
            separateInheritedMembers = true
        }
    }
}

But I still get all the superclass stuff in the same view.

[Lukas K-G]

this needs to go in the pluginsMapConfiguration. Do you have .gradle or .gradle.kts?

[zsmb]

Regular .gradle files

[Lukas K-G]

Bad luck. Now it is getting ugly. 😬 You need to add the following:

[Lukas K-G]

pluginsMapConfiguration.set(
            ["org.jetbrains.dokka.base.DokkaBase": """{ "separateInheritedMembers": true}"""]
    )

[Lukas K-G]

I hope I got all the brackets right. 🙈

[zsmb]

Hmm, where do I add this? It’s an Android project, so there’s a top level Gradle build file, and then per-module ones as well.

[Lukas K-G]

see https://github.com/Kotlin/dokka/blob/39cceaa3af6df5c419b9cd1f3d880ac8cf7d94a5/integration-tests/gradle/projects/it-basic/build.gradle.kts#L51 for reference.

[zsmb]

Ah, got it, within the Dokka task config - I’ll give it a spin, fingers crossed 😄

[Lukas K-G]

I had to change the maven repo and the dependency on my side:

maven {
            url '<https://maven.pkg.jetbrains.space/kotlin/p/dokka/dev>'
        }

and

classpath("org.jetbrains.dokka:dokka-gradle-plugin:1.4.20.2-dev-62")

[Lukas K-G]

Should produce something like this:

[zsmb]

I got this new version, and have this as my config in each of my modules:

dokkaHtml.configure {
    pluginsMapConfiguration.set(
            ["org.jetbrains.dokka.base.DokkaBase": """{ "separateInheritedMembers": true}"""]
    )
}

But I don’t get the separate tab yet 😞

[zsmb]

I’ll try putting this config on the dokkaHtmlPartial task instead

[Lukas K-G]

For me it looks like this:

tasks.withType(dokkaHtml.getClass()).configureEach { 
 dokkaSourceSets {
....
}
 pluginsMapConfiguration.set(
            [
                    "org.jetbrains.dokka.base.DokkaBase": """{ "separateInheritedMembers" : true, "customStyleSheets": ["${file("../documentation/logo-styles.css")}","${file("../documentation/styles.css")}"], "customAssets" : ["${file("../documentation/docs_logo.svg")}", "${file("../documentation/logo-icon.svg")}"]}"""
            ]
    )
}

[Lukas K-G]

But that should not make any difference I think. Are you sure you have the dev version? The logo in the top left should be a link now if so.

[zsmb]

Ah, awesome, got it to work

[zsmb]

I’ve added so much config that I’m not sure which one it needed, I’ll have to binary search for it now 😄

[Lukas K-G]

😂 good luck.

Disclaimer: There is nothing officially documented as far as I know. I just found it by looking trough code. So use at your own risk. 🚀

[zsmb]

Understood, thank you for all the help! 🙇

I found two stable configs. I’m running gradlew dokkaHtmlMultimodule which runs dokkaHtmlPartial in each module, so I need either of these config blocks for this to work:

dokkaHtmlPartial.configure {
    pluginsMapConfiguration.set(
            ["org.jetbrains.dokka.base.DokkaBase": """{ "separateInheritedMembers": true}"""]
    )
}

tasks.withType(dokkaHtmlPartial.getClass()).configureEach {
    pluginsMapConfiguration.set(
            ["org.jetbrains.dokka.base.DokkaBase": """{ "separateInheritedMembers": true}"""]
    )
}

[Lukas K-G]

Quick not: dokkaHtmlPartial.getClass() is just a way to get the DokkaTask class. I did not find any other solution. So this runs for all tasks of type DokkaTask.

[zsmb]

Apparenty it matters whether it’s dokkaHtml.getClass() or dokkaHtmlPartial.getClass() , the former doesn’t work

[zsmb]

Printing them shows that they return slightly different values

class org.jetbrains.dokka.gradle.DokkaTask_Decorated
class org.jetbrains.dokka.gradle.DokkaTaskPartial_Decorated

[Lukas K-G]

Oh, good to know!
