These are picked up by Emacs Flycheck and overlayed in the
editor and listen in the *Flycheck errors* buffer. Very
convenient. When I want to get the type of something at
compile-time.
In order to not having to repeat oneself I'm now looking for a
way to extract this into a `mixin template`. Is this possible
somehow and still preserve the instantiation site values of
`__FILE__` and `__LINE__`?
mixin template ctLog(string msg, string file = __FILE__, size_t
line = __LINE__) {
pragma(msg, file, "(", line, "): ", msg);
}
mixin ctLog!"Module scope";
unittest {
mixin ctLog!"function scope";
}
struct S {
mixin ctLog!"Struct scope";
}
This works for me.
