Provide Gradle Kotlin DSL examples in documentation

[aalmiray]

As explained at gradle/gradle#6790; follow tabbed alternative shown by @bmuschko at bmuschko/gradle-docker-plugin#677

This is great news. I wonder if you had seen this post before for choosing DSLs via tabs?

The advantages of the approach in the post are

• User DSL preferences are remembered client-side
• Neato little Groovy and Kotlin logos for your tabs and file names
• No need to include zepto/jquery/etc just for this

Related, I have had a TODO to open source the asciidoctor extensions that Gradle uses here that make samples authoring in Asciidoctor particularly nice. Is that something you'd be interested in?

[aalmiray]

I think I missed the post. I went with @bmuschko's option because I recently saw him demoing the docs at Voxxed Days Banff. However I like the logos on tabs, so I may give that DSL a try.

Yes, I'd love to help open sourcing stuff. I'll be at Devoxx BE next week, perhaps it's something to be discussed with @jlstrater? 😏

Sure! Let's chat when you have some time.

I am sure the community would appreciate an AsciiDoctorJ extension for their multi-lingual plugins. 👍 The entry barrier for writing such docs should be as low as possible.

[aalmiray]

Indeed. But in order to appeal to a much wider audience such extension should be written in Ruby and its language recognition should be pluggable, not just Groovy and Kotlin as it currently stands 😄
