Hello.

Can please anybody help me create template format2 like std.format.format,
so it can access to format string (change it for example)
then instantiate std.format.format template in compile-time-checkable way
format!"%d %s"(arg1, arg2)
so compiler can check format string vs arguments count at least.

i.e. if i would write
format2!"%d %s"(arg1)
i should give comile time error

and next difficulties, i want format2 have extra parameter (say "prefix"), not passed to std.format.format

for example, format2 should prepent prefix to format string then instantiate std.format.format

any advices
thanks

Since std.format.format already does this, just create templates that simply pass on their arguments to it and let it validate them. "Prefixing" the format pattern is trivially done (in a separate template) before deferring to format.

If you're not familiar with templates and the difference between compile-time and runtime parameters, there are several good write-ups, such as the template chapter of Ali Çehreli's book (which is available online at http://ddili.org/ders/d.en/templates.html).
