Hi all,
I recently discovered lexical_cast, and it's very nice and elegant.
I'd like to put in a feature request, though: the ability to use a
default value rather than throwing an exception on conversion failure.
Basically, it would take a second argument that would be the value
returned if the conversion fails. This could be used directly in the
example, like:
std::vector<short> args;
while(*++argv)
{
args.push_back(lexical_cast<short>(*argv, 0));
}
This eliminates the throwing and catching of an exception for cases
where conversion failure is not an exceptional.
I've attached a patch to lexical_cast.hpp found in Boost 1.32.0
