Re: Question: what's the benifit of compile in database support?

I just think this is a very useful backend for some asian input methods. 3~4 years ago there is a very famous GPLed chinese input method(wrote in cpp) named xsim, which is using bdb as its database backend. And maybe some chinese user will be interested in porting that input method into XEmacs :D If they know XEmacs have a bdb database backend support...

Just the docstrings, I'm afraid. F1 f open-database RET , F1 f get-database RET, and the other most relevant functions are map-database, put-dabase and remove-database. The code isn't used much, probably because this support is not available under GNU Emacs. I intend merging a very hacked version of their descr-text.el that uses the database support to store index information for Unihan.txt in the next few weeks though, so that will change a little. -- ¿Dónde estará ahora mi sobrino Yoghurtu Nghé, que tuvo que huir precipitadamente de la aldea por culpa de la escasez de rinocerontes? ____________________________________________________________________________________ Be a better sports nut!
