== DPL3 Date Formatting in Tables ==

When using [[https://www.mediawiki.org/wiki/Extension](https://www.mediawiki.org/wiki/Extension):DynamicPageList3 DynamicPageList3 (DPL3)] to build version history or changelog tables, you may run into issues where the '''date values appear unformatted''', even when using a helper template like <nowiki>{{OOO date}}</nowiki> that works elsewhere.

This page documents the root cause and solution.

=== Problem ===
DPL3 inserts data (like <nowiki>%%</nowiki> placeholders) '''after MediaWiki's parser has already run'''. So if you try this in a <code>tablerow</code>:

<syntaxhighlight lang="text">
| tablerow = [[%PAGE%|%%]], {{OOO date|%%}}, %% , %%
</syntaxhighlight>

...the template <nowiki>{{OOO date|%%}}</nowiki> is not parsed as a real template call. It just outputs as literal text, or sometimes breaks the row entirely.

=== Solution ===
Use '''DPL’s delayed evaluation syntax''':

<syntaxhighlight lang="text">
| tablerow = [[%PAGE%|%%]], ²{OOO date¦%%}², %% , %%
</syntaxhighlight>

'''Explanation:'''

* <code>²{</code> and <code>}²</code> (superscript 2) tells DPL to defer the parsing of the template call.
* <code>¦</code> (section divider character) replaces the normal <code>|</code> pipe so DPL doesn't misinterpret it as a column split.
* The result is equivalent to <nowiki>{{OOO date|2023-12-03}}</nowiki> at render time — and the date displays correctly as, for example, "December 3, 2023".

=== Example ===
If you're using an infobox like [[Template:Version infobox]] with a <code>date</code> field, and you want that formatted in your auto-generated table using the parser function form of DPL:

<syntaxhighlight lang="text">
{{#dpl:
| category = Updates
| namespace = Main
| ordermethod = sortkey
| order = descending
| include = {Version infobox}:version:date:type:summary
| table = class="wikitable sortable",-,Version,Date,Type,Summary
| tablerow = [[%PAGE%|%%]], ²{OOO date¦%%}², %% , %%
}}
</syntaxhighlight>

This ensures every row uses the same readable date format consistently.

=== Notes ===

* The [[Template:OOO date]] template should handle fallback and formatting via <nowiki>#time</nowiki> safely.
* This technique works with both <nowiki>{{#dpl:}}</nowiki> and (in theory) <nowiki><dpl></nowiki> tag usage, though this example uses the parser function form.
* The <code>²{...}²</code> technique is also useful for wrapping <nowiki>#arraymap</nowiki>, <nowiki>#iferror</nowiki>, or even <nowiki>#invoke</nowiki> calls inside DPL output.

=== See Also ===

* [[Template:OOO date]] — helper template used for formatting
* [[Template:Version infobox]] — where the raw <code>date</code> param is defined
