Hey,
I am maintainer of the Maps extension for MediaWiki.
https://github.com/JeroenDeDauw/Maps#maps
Recently I worked on improving integration with Visual Editor. Maps used to
not show up as a grey box [0] since their initialization JavaScript was not
being run. I got things working but am not happy with the solution and hope
there is a better approach.
After some searching I found that if I ran the initialization code in a
handler to the ve.activationComplete hook, the maps would get initialized
as desired [1]. That is not a complete solution though, since you can edit
the maps with Visual Editor [2]. This causes an API request that parses the
new wikitext to HTML, which then replaces the old HTML of the initialized
map. So initialization needs to happen again.
An hour or two searching through the docs and Visual Editor code did not
yield any usable hook/event. (This was quite surprising to me. Has no one
ever done something similar to what I am doing here?) So I settled on just
running initialization once every second with setInterval(). I found the
ve.deactivationComplete hook which I then used to stop the code running
every second on saving and existing the visual editor. Turns out that when
opening the visual editor after that does not result in a new
ve.activationComplete event, hence I had to remove termination of the
repeating initialization.
Surely there is a better way to run my code once per second (ad infinitum)
starting with Visual Editor activation? The perfect event for my usecase
would be "visual editor rendered a parser function". A broader event (ie
"something got rendered") would still be better than nothing.
You can see my current code here [3], including a few commented out bits
which I left in so you can see some of what did not work.
