Hi Marco,

there is the indent option for the source block that allows you to normalize the indent. You can even specify the tab size. https://asciidoctor.org/docs/user-manual/#normalize-block-indentation

[source,ruby,indent=0]
----
include::file.rb[tags=init]
----

I assume this is what you have been looking for.

Cheers, Alexander
