Data Structures

Ramen makes use of a simple "struct" facility. Used for structs that are passed on the stack. (Objects don't use these words.)

To declare a struct say struct <name>

sfield ( struct bytes valtype -- <name> ) ( adr -- adr+n ) defines a struct field.

svar ( struct valtype -- <name> ) is short for struct cell 0 sfield.

Valtype is obsolete and not used so you can set it to anything.

sizeof gets the size of a struct.

Example:

struct color
    color 0 svar color.r
    color 0 svar color.g
    color 0 svar color.b
    color 0 svar color.a
