Hi, This is an interesting observation. So it seems reasonable to drop back to 1.32 version. Ideas? Regards, Pavol On Wed, Jul 13, 2005 at 04:42:06PM +0200, Jan Hermelink wrote:
The 1.32 behaviour is compatible with Boost.Regex:
boost::regex_token_iterator in splitting mode returns for
"abc/abc/" -> 2 tokens
This is compatible with the regex standardization proposal.
I think the behaviour of boost::split should be the same.
Regards,
Jan

hi,
I assume the behaviour of boost::split not to return the last token has been changed (in CVS). However, a side effect seems to be that there is also one token returned for _empty_ strings, which is very questionable IMO!
summary (if '/' is the separator):
boost 1.32: "" -> 0 tokens "abc/abc" -> 2 tokens "abc/abc/" -> 2 tokens
CVS: "" -> 1 token (!) "abc/abc" -> 2 tokens "abc/abc/" -> 3 tokens
should be IMO: "" -> 0 tokens "abc/abc" -> 2 tokens "abc/abc/" -> 3 tokens
Thoughts?
Stefan
