Description

Problem

The PST features in wikitext are things like ~~~~ (becomes a signature on-save), and {{subst:#time:}} which can insert the current date.

These can be used in templates and in passing text, but not inside extension tags such as <ref> or <gallery>.

Use cases
  • Adding a signed caption inside a gallery, for example on a wikiproject page, or talk page. <gallery>File:Example|I like this one. ~~~~</gallery>.
  • Using the current date as the default for template parameters. <ref>{{Cite web|title=|url=|access-date={{subst:#time:Y-m-d}}}}</ref>
Original bugzilla description by dbenbenn:

See [[User:Dbenbenn/sandbox#Gallery_pipe_trick]], for example. A
link in the caption of a gallery image ending in |]] is broken.

Gabriel: As you assigned this report to yourself two years ago, do you plan to rework the two patches? Or are they "somehow" obsoleted in the meantime?

I was tooling around with this, but...

https://www.mediawiki.org/wiki/Manual:Tag_extensions#How_do_I_render_wikitext_in_my_extension.3F

This section says that tag extensions will never have PSTs applied to them. So maybe this bug is WONTFIX and we should abandon all patches for it?

This bug is not only/mainly about tag extensions: see pipe trick, subst, signatures.

AdamCuerden raised the priority of this task from High to Unbreak Now!.Sep 24 2015, 8:58 AM

this has surely gone on long enough, with maqsses of lost resources.

Aklapper lowered the priority of this task from Unbreak Now! to High.Sep 24 2015, 9:37 AM

This task has not suddenly become more urgent than before, hence reverting the recent Priority change. See https://www.mediawiki.org/wiki/Phabricator/Project_management#Setting_task_priorities for more information. Thanks.

Am I correct in thinking that {{subst:CURRENTMONTH}} and {{subst:CURRENTYEAR}} not being substituded in this edit is due to this bug?

Yes, substituting within refs won't work if this bug is not resolved!

@Thryduulf use {{#tag:ref|}} or {{subst:#tag:ref|}} and it will work

and I would love to see this added to the projects for fixing that are coming up. It is truly time that this got resolved for all wikis.

@Billinghurst add an entry to https://meta.wikimedia.org/wiki/2017_Community_Wishlist_Survey (I guess it would fit in the editing section?).
