Did anyone ever get a chance to look at this feature and patch? I could do the documentation updates, too, if desired. -Dave On Apr 15, 2005, at 3:05 PM, Dave Dribin wrote:
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
