You can put them in the runtime parameters:
----
void traceVars(alias T, U...)(size_t line = __LINE__, string file
= __FILE__) {
import std.stdio : writeln;
writeln(file, "(", line, ") ", T.stringof, ": ", T);
static if (U.length > 0) {
traceVars!(U)(line, file);
}
}
----
Or you can nest two templates:
----
template traceVars(alias T, U...) {
void traceVars(size_t line = __LINE__, string file =
__FILE__)() {
import std.stdio : writeln;
writeln(file, "(", line, ") ", T.stringof, ": ", T);
static if (U.length > 0) {
alias t = .traceVars!U;
t!(line, file);
}
}
}
