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?
In some ways I agree with you, but I think it may be more consistent to output an empty token for an empty string as long as other empty tokens are kept. However, I can see arguments for and against both ways. Does anyone know what other libraries/languages do in this situation? Scripting languages typically have a split() function, but I haven't tested this particular case. -- Be seeing you.
