put two variables/macros together in brackets if they have a value

meiernik

Hello dear community.

I try to edit a zotero-style.
Currently, the entry I'm interested in is as follows:
<text macro="issuance" prefix=" (" suffix=")"/>

Now I want to add in the same brackets of "issuance" also the court who rendered the judgment ("authority"), but only if I have specified an authority.
I tried it with the following:
<text variable="authority" prefix=" (" suffix=" "/>
<text macro="issuance" prefix=" " suffix=")"/>

The problem is that a bracket is now missing if I have no authority specified...

Can cou please help me with a "if X then Y"-formulation?
(if "auhority" is defined, then put "authority" before "issuance" in the same brackets).

Many thanks for your valuable help!

<group delimiter=" " prefix="(" suffix=")">
<text variable="authority"/>
<text macro="issuance"/>
</group>

I very much recommend becoming familiar with groups&delimiters. They'll make your styles much more robust. See my longer discussion on this at my blog:

just in case that wasn't clear--I didn't link to the post to imply you were asking a "dumb" question; I just figured it might be helpful. We're happy for people to learn CSL and happy to answer questions.
