The compose and format API saves C++ from gettext a lot. And it reminds
me a similar library of boost::format , which basically does the same
thing, but provides different interfaces. I'm not an expert, but I
believe the Boost one might be better than yours in the following 2 aspects:
1. format-string specification
boost::format retains the old printf format (%spec), and provides more
flexible syntax, such as %|spec| which can omit the type-conversion
character, as well as %N% which plays as place holder, while you were
using %N as place holder. The lack of printf-like format might results
in incompatible interfaces with plain printf and might compromises the
interoperability of format string with other printf-like functions.
Though they are definitely not good choices, they are still widely used.
However, you can implement the same thing of course :)
Boost uses operator% to concatenate different part, which is generally
type safer than variadic function calls, and might provides more
flexibility in implementation before C++ allows overloading operator,.
Moreover - I think its less important - that boost::format has already
been used for a while. Providing a similar syntax will of course
increase the interoperability with many existing code using
boost::format as well.
Again, I'm not an expert, and I've no rights to judge anything, and your
library has been written out for quite some time already. But I wish you
may consider my proposal, and thanks for your effort :)
