Let's talk about macros about ctod

[dkorpel]

Can we explore other options?

Of course, do you have examples of macros and their desired translations?

[schveiguy]

For a start, I think the macro call should be translated as if it were actually a mixin:

pixels[y*image.width + x+1].r = mixin(MIN!("cast(int)pixels[y*image.width + x+1].r + cast(int)(cast(float)rError*7.0f/16)", "0xff"));

And really, the enum needs to be a true concatenation:

enum string MIN(string a,string b) = `(((` ~ a ~ `)<(` ~ b ~ `))?(` ~ a ~ `):(` ~ b ~ `))`;

Does it need to be an enum? Maybe not, but then it just makes a new function to be linked...

It's now adding mixin to call macro functions, and concatenates the arguments properly. There's still a lot to improve, so please report any failure cases you encounter.
