This requires the input range to supply BidirectionalIterators, which is not a problem for where it is currently useful to us. The alternative would be to not invoke --last;, and instead create an output iterator similar to std::ostream_iterator, but which puts the delimiter before the item to output. --- Source/cmStandardIncludes.h | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) diff --git a/Source/cmStandardIncludes.h b/Source/cmStandardIncludes.h index e4f5760..d7c6a65 100644 --- a/Source/cmStandardIncludes.h +++ b/Source/cmStandardIncludes.h @@ -358,6 +358,33 @@ static thisClass* SafeDownCast(cmObject *c) \ } \ class cmTypeMacro_UseTrailingSemicolon +template +std::string cmJoin(Range const& r, const char* delimiter) +{ + if (r.empty()) + { + return std::string();
