Summary: To find all arguments of an instantiated template Product: D Version: D2 Platform: All OS/Version: All Status: NEW Severity: enhancement Priority: P2 Component: DMD AssignedTo: nob...@puremagic.com ReportedBy: bearophile_h...@eml.cc --- Comment #0 from bearophile_h...@eml.cc 2013-08-25 09:56:55 PDT --- Given an instantiated template like: struct Foo(T, U, size_t n) {} alias F1 = Foo!(int, float, 5); In many situations for me it's going to be useful a built-in trait (or a Phobos template with the same semantics) that returns a TypeTuple of the original template plus all the arguments used to instantiate it: __trait(templateArguments, F1) ==> TypeTuple!(Foo, int, float, 5) That means something like this should work: alias TT = __trait(templateArguments, F1); static assert(is(F1 == T[0]!(TT[1 .. $][]))); It should work with variadic templates too. I have tagged this as dmd enhancement, but if a full library implementation is possible, then this is meant just as a Phobos enhancement. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
