Expanding {{Field}}s in _global.html

[khonkhortisan]

{{Tags}}, or {{info::Id}} from Additional Card Fields (Fork for 2.1) https://ankiweb.net/shared/info/744725736 don't expand after injection. It would be nice to be able to use this for adding the subject on a card based on tags, or as a seed for randomizing multiple choice questions in javascript without having it randomize differently on the front versus the back side.

I'll dig around the Anki code later to try to figure out where it substitutes the {{Field}}s. We currently use the prepareQA hook to inject, so we don't very much choice as to when it gets called. I can look into monkey-patching the page render method to try to inject the content earlier. Edit 1 The relevant code is in anki/template/template.py. Looks like the substitution is first performed at anki/collection.py:579. Edit 2 We have to get the content injected before template.render() is called (see anki/template/template.py:55).

Incidentally, I did something similar to your randomization problem using Cookie monster. You can just store a randomly generated number in a cookie in the question and then retrieve it in the answer.

Another option would be to manually call the substitution on the content while injecting it

I confused myself with a series of hacks

inject+="<script>"
inject+="var mw_reviewer_state='"+str(mw.reviewer.state)+"';"
inject+="var mw_reviewer_card__note_tags='"+" ".join(mw.reviewer.card._note.tags)+"';"
inject+="</script>"

<div id="tags" align=right style="font-size:8px;color:grey;position:absolute;bottom:0;right:0;z-index:-1;">{{Tags}}</div>

document.getElementById("tags").innerHTML=mw_reviewer_card__note_tags;
⋮
alert("tags: "+document.getElementById('tags').innerHTML);

I ran into this again with

<svg width="100%" height="100%" data-jdenticon-value="{{info-Id:}}" style="position:absolute;left:0;top:0;z-index:-1"></svg>
