In general you have to think about that any application will have the hit of that method in their app as soon as they call String.format one time in their code base. > > What about a minimal positional substitution implementation and nothing more? > > Right now any code that relies on String.format will not compile in GWT and thus give the author a clear indication of having a problem. Once we support a subset this compile error might be gone, but we will be introducing runtime errors for not supported features rather than compile time errors. One could try to deal with these (and this is bad from the compiler perspective), by looking at the parameters of String.format and only allow statically resolvable arguments for the format String that are supported by the emulation, but this is a very tight coupling of compiler and lib that we do not want in the compiler. So if we want to do a minimal support of String.format these are the kinds of problems we need to discuss. > -- > You received this message because you are subscribed to the Google Groups > "GWT Contributors" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to google-web-toolkit-contributors+unsubscr...@googlegroups.com. > To view this discussion on the web visit > https://groups.google.com/d/msgid/google-web-toolkit-contributors/bc6afdc0-eb87-4815-b076-6db912f8f94c%40googlegroups.com > <https://groups.google.com/d/msgid/google-web-toolkit-contributors/bc6afdc0-eb87-4815-b076-6db912f8f94c%40googlegroups.com?utm_medium=email&utm_source=footer> > . > For more options, visit https://groups.google.com/d/optout. > -- Google Germany GmbH *Dienerstr. 12* *80331 München* Registergericht und -nummer: Hamburg, HRB 86891 Sitz der Gesellschaft: Hamburg Geschäftsführer: Graham Law, Katherine Stephens -- You received this message because you are subscribed to the Google Groups "GWT Contributors" group.
