Subject: [PATCH v4 2/3] ox-texinfo: Optionally use @itemx for certain description list items
Date: Sun, 23 Jan 2022 21:27:39 +0100 [thread overview]
Message-ID: <20220123202740.512619-3-jonas@bernoul.li> (raw)
In-Reply-To: <20220123202740.512619-1-jonas@bernoul.li>
* doc/org-manual.org (Plain lists in Texinfo export): Reorder and
document new functionality.
* lisp/ox-texinfo.el (org-texinfo-item): In a description list when
its :compact attribute is non-nil, then transcode consecutive items
using one @item and one or more @itemx commands, if all of them
except for the last one lack content.

+The =:compact= attribute is an alternative to the =:sep= attribute,
+which allows writing each entry on its own line. If this attribute is
+non-nil and an item in a description list has no body but is followed
+by another item, then the second item is transcoded to =@itemx=. This
+example is transcoded to the same output as above.
