Template:Requires

Template documentation (for the template shown above, sometimes hidden or invisible)

Description

This template executes a specific Ask-query, related to the page its used on, and return the resulting values(page-names) into Required items.

Or: A Ask-query result like "abc, def, ghi" becomes "[[requires::abc]], [[requires::def]], [[requires::ghi]]"

Currently created to process tree-lists for general tree products. (as there are a lot of trees, and (some) tree products have there own useful properties for this)

Usage

Default: {{Requires|<Property-Name>}}

It will look in the target property for {{PAGENAME}} items.

Usable properties

Trees barktype

Trees branchtype

...

Caveat

To do this inside a single template the returned Ask-Query is generate first, and than re-processed in its entirety.

... Meaning this can only handle strings within a certain lengt (1000 characters).

... As expected it will fail when used on the "Treebark" page. To many trees returned in that case.
