Is there any way to generate an equivalent to Special:WantedTemplates to show missing modules?
Topic on Extension talk:Scribunto
I thought S:WantedTemplates already listed modules, but after testing, much to my surprise it does not. It looks like the relevant Phab ticket is phab:T104002.
I'm surprised that would even work, with Modules. A missing module results in a Script error: No such module... message from Scribunto, not a redlink. (Redlinks are how the other "Wanted ..." lists get populated.)
I'd have expected the issue to be that Scribunto itself needs to track missing modules. After all, {{#invoke:}}
will never be missing as long as Scribunto itself is installed. But, maybe it already knows how to track those script failures as "module redlinks".
Yes, it does and should track script failures as redlinks – treating them as readlinks ensures that the script failures go away once the module is created, otherwise the parse result with the script error could get stuck in the cache.
