With printf, you can do it this way: > > fr: " %s %d" > > string -> int > > de: " %2$s %1$d" > > int -> string > > This example shows that if you want a full featured internationalisation, > you cannot state that "you know the type you expect" since you will only > determine it at run-time. this only shows that " %2$s %1$d" is not a valid translation of " %s %d", since they do not have the same type, and would fail at runtime (using this in C would give you a segfault). " %2$d %1$s" with type "string -> int" is a valid translation of " %s %d" this means that not checking the translations could lead to a hole in the type system, and so printf must be prepared to detect type errors (which it currently does :) ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners
