@define in docs

[Bill Hart]

Hi,

I just noticed that the following example does not compile for me from the docs:

@ import crack.ann define;

@define max(Type) {

   Type max(Type a, Type b) {

       return a > b ? a : b;

   }

}

int a = 3, b = 5;

x := @max(a, b); 

It seems like one has to do:

@max(int)
int a = 3, b = 5;
x := max(a, b);
though that seems to not be the intention of that example.
Bill.

Hi Bill,

@max is the name of the define, and it takes only one argument.

The code for the max() function is injected when the macro is 'called'
with @max(int).

This is similar to the C #define:
#define func(Type) function func(Type a) { return a*2; }

(In C it would be a bad idea to name the define and the function the
same name, but Crack allows you to do that because @func is different
from func)

Hope this helps,
Conrad
