I've been studying metaprogramming and reviewing many documents and code regarding boost files. What I've been trying to understand and accomplish is creating various types using
typedef
,
template
and
struct
, similar to that of the boost files themselves, to create comparators. Ultimately, I want to be able to create a type that has subproperties which can be further compareded and classified.
I apologize in advance as I cannot provide any working attempt at this. I am in the struggle.
Informal example:
create type
typedef int coordinate[3];
create standards  "typeless prototypes"
1 2 3

static const coordinate _x = {1,0,0};
static const coordinate _y = {0,1,0};
static const coordinate _z = {0,0,1};
 
We "now have" three variables under one unique type. Now I want to wrap this further to work with other types (int, float, etc.).
create special cases
1 2 3 4 5 6 7

template<class ty, coordinate c> struct coord_type;
typedef coord_type<int,x> x_i;
typedef coord_type<float,x> x_f;
typedef coord_type<int,y> y_i;
typedef coord_type<float,y> y_f;
typedef coord_type<int,z> z_i;
typedef coord_type<float,z> z_f;
 
declare more standards
1 2 3 4 5 6

const x_i i_i;
const x_f i_f;
const y_i j_i;
const y_f j_f;
const z_i k_i;
const z_f k_f;
 
Where other variables can be represented based off this i,j,k standard and written in a more direct vector form.
And so on...
I don't know how helpful this is to those of you who are more experienced with this sort of style, but what I essintially would like to do is have
x,y,z
variables act as standards for an i,j,k system that classify arbitrary variables of the coordinate type: Is the arbitrary variable i, j, or k? Is it defined as an int or float type?
Where arguments such as
sum_y = var1 + var2;
are valid, provided:
sum_y
is outputted as 6j, and
var1
and
var2
are 2j and 4j, respectively.
Please don't overanalyze what I have provided. Just focus on the concept I am bringing forward. I know that the examples above are rough, but I myself don't know all the ins and outs for how to approach this.
Thank you for your time. All help and suggestions are appreciated.
