Re: Preserving of text properties

In XEmacs there are three interfaces to one way to attach information to text: the native extent interface, the sanctioned text property interface, and the deprecated overlay interface. In each case, the text being treated is marked out with an extent, and a property is set on the extent. Text properties set using the text property interface should be preserved (and are, in the cases I know about). Properties set via the extent interface and the overlay interface are not. It seems likely to me that there is a fair amount of confusion in the XEmacs documentation about this, as much is ported directly from the Emacs docs, where IIRC text properties and overlays don't share implementation at all. And we could have gotten the behavior wrong, too. -- Institute of Policy and Planning Sciences http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
