Macro Definition Documentation

NAME

#define NAME   self_t

Supporting templates that internally invoke new templates.

Ideally we could do:

#define SELF foo
 
// within the template
#pragma push_macro("SELF")
#define SELF NS(SELF, internal_vector)
// ...
#include <derive-c/container/vector/dynamic/template.h>
 
// ...
 
#pragma pop_macro("SELF")
 
// The rest of the structure definition ...

However, this is not possible, as macros are not eagrely expanded at definition

• We cannot 'save' a macro, and redefine it in using its previous/saved value

To solve this, there are a few options

1. For the user to provide names for internally used data structures
2. A more complex scheme of stacking internal names (name 1, 2, etc)
3. Namespace all macro paramaters (e.g. VECTOR_SELF, HASHMAP_SELF etc)

To keep code simple, but allow definitions to uniformly use SELF:

• We restrict to 1 layer deep - NAME (from user), and INTERNAL_NAME (usage inside a template file, one layer deep).
