element inside ?

nickbart

I have been trying to get chicago-author-date.csl to cope with unsigned articles and reviews, where the name of the newspaper or periodical needs to stand in place of the author (see CMoS 14.207 and 14.217).

Duplicating <macro name="title"> to, say, <macro name="noauthor_title">, and having the latter return the container-title in case the type is article-journal, article-magazine, or article-newspaper seems to work as expected.

Trying what seems to be a simpler solution, i.e., inserting a <choose> element into <substitute>, along the lines of<macro name="author">
<names variable="author">
<substitute>
<names variable="editor"/>
<choose>
<if type="article-journal article-magazine article-newspaper" match="any">
<text macro="container-title"/>
</if>
</choose>
<text macro="title"/>
</substitute>
</names>
</macro>however, I got confusing results. Before I investigate further, my question: is it legitimate to use <choose> inside <substitute> in the first place?

That should work, but I work wrap the cs:choose in a macro for readability.

Whatever variables are actually rendered via cs:substitute will be suppressed in the remainder of the cite.

(Edit: Also, your condition should trigger only when a container-title is present, and fall back to title otherwise. That would call for folding the attempt to render the title into the same condition.)

@fbennett - Thank you for the hints. It seems the patch below works as expected now, for both Zotero and pandoc.

@adamsmith - Would you care to have a look, and possibly update the official chicago-author-date.csl as well as other chicago styles?

In case this wasn't too clear: The above is a proposal to patch the official chicago-author-date.csl.

Any comments? Would you prefer a pull request?

adamsmith

yes, pull request would be much easier, thanks.

nickbart

Done for chicago-author-date.csl. - Since the rule from 14.207/14.217 applies to all Chicago styles, would you be interested in pull requests for the others, too?

adamsmith

generally yes, but let me look at the pull request first.

fbennett

(I've posted a mea culpa to the pull request. As @aurimas pointed out there, folding everything into a single macro like I suggested was not necessary.)
