+\r
+No, --output=authors isn't currently available.\r
+\r
+> something like:\r
+> \r
+> $ notmuch search --output=authors from:Johannes\r
+> Johannes Kulick (1234 msgs)\r
+> Johannes Doe (123 msgs)\r

+> - add bindings for the other languages\r
+\r
+What's the advantage to adding this to the library?  Why not just\r
+notmuch_query_search_messages, iterate over the messages and use\r
+notmuch_message_get_header(msg, "from") to accumulate the author\r
+information, and then output that?  Unless I'm overlooking something\r
+(which is possible), there are no algorithmic advantages to doing this\r
+in the library.\r
+\r
+As David pointed out, for alot you could do this right away, since it\r
+uses the library directly.  For notmuch-emacs you would have to extend\r
+the CLI along the lines you're imagining.\r
