It's often necessary to update the representation of a single object in a table (e.g a struct, whose identity does not change when its slots' values are changed). To do so, now the function may be called like this: (vtable-update-object table object) Instead of like this: (vtable-update-object table object object) This also documents the behavior of the just-discovered limitation filed as bug#69837. * lisp/emacs-lisp/vtable.el (vtable-update-object): Make 'old-object' argument optional. (Bug#69666) * doc/misc/vtable.texi (Interface Functions): Update documentation. * etc/NEWS: Add news entry. |
