CSL: macro to abbreviate strings
Is there any way to truncate a title such as "Wie Käptn Blaubär die Pommes erfand" either by number of words or number of characters, i.e. something like "Wie Käptn Blaubär..." or "Wie Käptn Bl..."?
If it's a title, you can call
<text variable="title" form="short"/>
, which will print the short title if supplied in the Short Title field or similar.CSL has no way to automatically create short forms like this. You could try using the Abbreviations Filter plugin for Zotero, which might be able to do something like this.
