Contextual state machine (generator methods) implementation in basic C++, using mostly C constructs.
|
|
|
|
(TODO: Explain what is and isn't supported)
|
|
|
|
## Example
|
|
|
|
Output values of any type
|
|
``` c++
|
|
#include <sm/state.h>
|
|
#include <sm/gen.h>
|
|
|
|
#include <cstdio>
|
|
|
|
SM_GENERATOR(powers_of_two)
|
|
{
|
|
int* a = SM_VAR(1);
|
|
SM_BEGIN;
|
|
{
|
|
while( (*a) > 0 ) {
|
|
SM_YIELD_VALUE(*a);
|
|
(*a) <<= 1;
|
|
}
|
|
}
|
|
SM_END;
|
|
}
|
|
|
|
int main()
|
|
{
|
|
auto state = sm_new_state();
|
|
auto gen = sm_generate(&powers_of_two);
|
|
|
|
sm_output output;
|
|
int out_int;
|
|
while(sm_next(&gen, state, &output)) {
|
|
if(!sm_output_value(output, &out_int))
|
|
continue;
|
|
printf("Power of two: %d\n", out_int);
|
|
}
|
|
|
|
sm_free_output(&output);
|
|
|
|
sm_free_generator(gen);
|
|
sm_free_state(state);
|
|
|
|
return 0;
|
|
}
|
|
```
