Apologies to those seeing this twice, but it's important enough to announce widely.

Flow will start appearing more widely soon when we release a feature to allow users on certain wikis to opt into Flow on their user talk pages.

The most common thing you'll probably want to do on a Flow page is post a new topic.

For Pywikibot, that is pretty easy, since they have Flow support now. See https://www.mediawiki.org/wiki/Manual:Pywikibot/Flow .

For on-wiki scripts, you can use MessagePoster (you don't need to know if it's a Flow board ahead of time!):

--- var title = new mw.Title( 'titleString' ); var posterPromise = mw.messagePoster.factory.create( title ); posterPromise.done( function ( poster ) { poster.post( 'This is the topic title', 'This is the body of a message posted with MessagePoster' ); } ); ---

Depend on 'mediawiki.messagePoster' and 'mediawiki.Title'.

In some cases, you might want to check if a link is already there (e.g. to see if a warning template already included links to a particular policy). You can use prop=links for this.

Flow is based on an infinitely-scrollable list of topics, each of which is its own page. So to use prop=links, you may need to loop through a set of recent enough topics (e.g. 25) then combine them into a prop=links request, e.g. https://www.mediawiki.org/w/api.php?action=query&titles=Topic:Sojpiv245c... .

pywikibot has support for looping through topics.

Some bots need to check the header of a page for wikitext (e.g. a bot exclusion template). This can be done with view-header, but I don't think pywikibot has support for that yet (but it can be done directly). See https://www.mediawiki.org/w/api.php?action=flow&format=jsonfm&page=T... .

A better way to do this would be templatelinks, but I'm not sure if there is an API to show templates PageX transcludes.

For other questions, contact us at #wikimedia-collaboration . Or, if a certain tool needs Flow support and you're not sure where to start, you can file a bug (you can also reply here, but a ping in IRC would be appreciated).
