Up until this point, I have been using FormatString to format multi-language strings using numbered variables ($1, $2, etc.) – however, it is not cross-platform compatible.
Is there a sprintf-esque function that is cross platform that does the same thing? It wouldn’t need to allocate memory or anything – just need to be able to deal with numbered typed pseudo-variables that could be in different places in the string.
Boost is okay, if it provides a similar function.
I would have a look at boost::format. I’ve been using it for a while and it works very well.
Another option would be to use std::stringstreams for formatting the output. If you don’t want to or cannot use boost, that’s pretty much the only portable option, plus as a bonus the syntax is a little more readable IMHO.
Both libraries are type safe and thus much better and safer to use in a C++ context as well, compared to the usual C APIs.
