Subject: bug#74013: 31.0.50; make-vtable errors on an empty list of objects
Date: Fri, 25 Oct 2024 11:23:35 -0400	[thread overview]
Message-ID: <ieriktgfbpk.fsf@igm-qws-u22796a.mail-host-address-is-not-set> (raw)


1. emacs -Q
2. M-: (make-vtable :columns '("column") :objects '())
3. Observe an error like (wrong-number-of-arguments #<subr max> 0)

I ran into this when trying to display a list which can sometimes be
empty.  At the very least it would be nice for this to provide a better
error message.
