How can one detect transclusion depth?

Question

In MediaWiki, is there a standard pattern that you can include in a template body to detect depth of transclusion?

Specifically, let's assume Template:Myinfobox contains such a pattern that displays "native myinfobox call" for depth 1 transclusion and "transclusion call" otherwise.

Then, if page Mypage calls {{Myinfobox}} it should display "native myinfobox call" while any page that calls {{Mypage}} should display "transclusion call"

Does anyone know such a pattern that does not require the writer of Mypage to insert special markup or <noinclude> or <includeonly> tags?

As far as I know, no, there isn't. – Ilmari Karonen Dec 01 '13 at 15:23 — Ilmari Karonen, Dec 01 '13 at 15:23

Thanks for the pointers. I was aware of these but it's good to have them here. Right now I'm resorting to the following trick (using the terminology of my question): I have a home article parameter in the Myinfobox that the user of the template must set to the name of the page hosting the Myinfobox direct call. Thus Mypage will contain something like:

{{ Myinfobox | … | home article = Mypage | … }}

The Myinfobox template tests whether {{PAGENAME}} equals {{{ home article }}} to determine the message it outputs: "transclusion" in case the 2 values are different, "native" otherwise.

But this is clumsy and places burden on the template user.

Ah, that's indeed one way we do it, for instance in [`{{langcat}}`](https://www.mediawiki.org/wiki/Template:Langcat). — Nemo, May 01 '15 at 11:14

No, there is no such thing. However, you can learn some evil tricks and internals on expansion depth limits and branching at
