Wikimedia Technical Talks

Tech talks are short presentations with community question and answer sessions. They are usually under an hour in length and focus on a specific technical topic.

For information on setting up a Tech talk, see Project:Calendar/How to schedule an event

We usually present tech talks using Google Hangouts On Air, which makes them available on YouTube. There is a concurrent IRC office hour for questions on IRC, so the talks also appear there.

Speaker: Subbu Sastry, Principal Software Engineer

Topic area: Parsoid to PHP

Description:

This will be a talk in 3 (unequal) parts: (a) Parsoid history (b) Porting Parsoid to PHP: the whys and wherefores (c) From here to Parsoid as the default.

Parsoid started in 2012 as a project to support Visual Editing and since then has gone on to support a number of products (Flow, Content Translation, Kiwix, and Android app). Given that (a) Parsoid's annotated HTML output enables clients to infer things about wikitext without having to parse wikitext, (b) the PHP parser cannot support Visual Editor and other products, and (c) we cannot continue to have two parsers, it is inevitable that Parsoid will be the default parser for MediaWiki. This has been known since at least 2015 but while we are nearer to that goalpost, we are still not quite there yet. In this talk, we'll talk about what else needs to be completed, and what the porting of Parsoid to PHP means for this goal.
