As I said, I wrote nonsense with regard to your question. Sorry for the confusion.
When would generate() fail (return false)?
Generate fails either if one of the used generators fail or if the underlying output iterator reports an error.
AFAIK to hex can't fail and in that case a variant that returns std::string would be nicer.
Sure it can. The container that you are putting it into (std::string, say) could fail on memory allocation. Just because it's really unlikely doesn't mean it can't happen. (If you don't want to worry about it, then don't)
Doesn't it 'return' a std::string? If you dislike the current API a small wrapper function can easily handle that.
Right - like this (for example): std::string hexS ( const std::string &input ) { std::string result; result.reserve ( input.size () * 2 ); // Harry Harrison hex ( input, std::back_inserter ( result )); return result; } ( I apologize for my idiosyncratic commenting style; I tend to figure everyone knows that Harry Harrison wrote a science fiction novel titled "Make Room! Make Room!" ) http://en.wikipedia.org/wiki/Make_Room!_Make_Room!
But just to avoid confusion: what API are you looking for?
std::string("61626f6465") --> std::string("abode")
or rather:
0x61626f6465UL --> string("abode")
(none of which can be easily done with Spirit, btw).
