I suppose you wish to treat a String object as an IO object? If so, I'll say it's not written yet, but could be by 2002. Depends on whether you want to pair with me. It would be an abstract IO class (possibly broken down in smaller pieces) and an application piece of code similar to the one below. The opposite, IO as String, has not been done yet either, but it will be done in 5 minutes... [...] done! ;-) require "Hollow/String" # from M?taRuby 0.7 class IOAsString; include HollowString, SimpleStringP def initialize(io) @io=io end def get i; (get_seq i,1)[0] end def put i,v; put_seq i,1,v.chr end def get_seq i,n @io.seek i, IO::SEEK_SET @io.read n end def put_seq i,n,v n!=v.length and raise "can't insert nor delete, sorry!" @io.seek i, IO::SEEK_SET @io.write v end def length @io.seek 0, IO::SEEK_END @io.tell end end ________________________________________________________________ Mathieu Bouchard http://hostname.2y.net/~matju
