## AuroraForEach
|
|
|
|
Implements a `AU_FOR_EACH_n` X-style macro that accepts a macro parameter where 'N' is the input parameters of the macro
|
|
|
|
## Example
|
|
```C
|
|
#define HELLO_WORLD(that, n) that n
|
|
#define COUNT_TO_9 AU_FOR_EACH_THAT(HELLO_WORLD, int, 1, 2, 3, 4, 5, 6, 7, 8, 9)
|
|
|
|
const char *kCountTo9 = AU_STRINGIFY(COUNT_TO_9); // generic what macro
|
|
assert(strcmp(kCountTo9, "int 1 int 2 int 3 int 4 int 5 int 6 int 7 int 8 int 9") == 0);
|
|
```
|
|
|
|
```C
|
|
#define HELLO_WORLD(n) n
|
|
#define COUNT_TO_9 AU_FOR_EACH(HELLO_WORLD, 1, 2, 3, 4, 5, 6, 7, 8, 9)
|
|
|
|
const char *kCountTo9 = AU_STRINGIFY(COUNT_TO_9); // generic what macro
|
|
assert(strcmp(kCountTo9, "1 2 3 4 5 6 7 8 9") == 0);
|
|
```
|
|
|
|
```C
|
|
#define HELLO_WORLD(n) , n
|
|
#define HELLO_WORLD_FIRST(n) 0, n
|
|
#define COUNT_TO_9 AU_FOR_EACH_FIRST(HELLO_WORLD_FIRST, HELLO_WORLD, 1, 2, 3, 4, 5, 6, 7, 8, 9)
|
|
|
|
const char *kCountTo9 = AU_STRINGIFY(COUNT_TO_9); // generic what macro
|
|
assert(strcmp(kCountTo9, "0, 1, 2, 3, 4, 5, 6, 7, 8, 9") == 0);
|
|
```

*Note, simple tests akin to the above examples may fail due to whitespace padding.*
