https://gerrit.wikimedia.org/r/#/c/223363/2/maintenance/FlowCreateMentionTemplate.php already has a maintenance script that creates the new FlowMentions template if it doesn't yet exist. Maybe we should change that script and make it loop an array( templatename => callback-that-returns-content ) of prerequisite pages to create?

Change 232489 had a related patch set uploaded (by Matthias Mullie):
Create all templates Flow uses

https://gerrit.wikimedia.org/r/232489

Current templates used by Flow, AFAIK:

• Template:FlowMention
• Template:LQT Moved thread stub converted to Flow
• Template:LQT page converted to Flow
• Template:Archive for converted LQT page
• Template:LQT post imported with supressed user
• Template:LQT post imported with different signature user
• Template:Wikitext talk page converted to Flow
• Template:Archive for converted wikitext talk page

For the creation script, I used their content from mediawiki.org. Is that content ok or do we want to simplify?

See also https://gerrit.wikimedia.org/r/#/c/232487/1

Below is the content of all import-related templates, as taken from mediawiki.org. What do we want to change these to?

I suggest we:

• drop everything inside <noinclude> and <includeonly>, they mostly just reference categories & templates assumed to exist on that wiki.
• drop <!-- --> comments
• remove {{Ombox}} and {{hatnote}} templates and just use the text

OK?

Sounds good to me.

Links in Template:LQT page converted to Flow and Template:Wikitext talk page converted to Flow should be wrapped in a span with a class. I think this could be the same for both. E.g.:

Previous page history was archived for backup purposes at <span class="flow-link-to-archive">[[{{{archive}}}]]</span> on {{#time: Y-m-d|{{{date}}} }}.
