[Addon dev] After changing `note.fields`, how can I ensure the changes to appear on editor web?

[trgk]

I’m the developer of Cloze (Hide All) addon. Recently I got a bug regarding the degraded performance of Anki cause of my addon. After profiling I found that this code was the culprit.

trgkanki/cloze_hide_all/blob/4d7d1353b735ccc480203fe08fc6b566127ec605/src/main.py#L95

Basically, on every saveNow the addon transforms HTML segments via Python code, do self.note.flush(). self.mw.requireReset() tries to copy the updated HTML code to web. I think this is necessary as the addon should coexist with other supposed addons which expects web content to match the python fields.

self.mw.requireReset() takes too long, so I wanna know if there’s a faster way to sync editor.note.fields back to the editor.web.

Alternatively, I can move all the processing code to JS side, but this would incur several other issues like my JS code should be able to access all Svelte-created contenteditable divs by index. (Which I don’t know how)

Thanks.

Did you try using the note_will_flush hook instead? Then you don’t have to do a reset.

It works. It seems like for editor opened during review, the callback won’t be called until the editor exits. So the addons do not properly transform the live-viewed edits on the reviewer. I think I can handle this case separately. Thanks!
