Reduction
Reduction is a sibling project to Deduction. Where Deduction "deduces" a JSON description from C/C++ files, Reduction "reduces" C++ libraries into C wrapper libraries based on that description. The intention is these wrapper libraries can readily be used to create bindings for other languages.
Example
Following from the Example used in deduction, reduction would produce two files.
The first will be a header file:
// examplelib-core.h
char const * const examplelib_version_info();
typedef examplelib_core_t void *;
examplelib_core_t examplelib_core_create();
void examplelib_core_destroy(examplelib_core_t core);
void examplelib_core_do_something(examplelib_core_t core);
The second will be the wrapper implementation:
#include <examplelib/core.h>
extern "C" {
#include "examplelib-core.h"
char const * const examplelib_version_info() {
return examplelib::version_info.c_str();
}
examplelib_core_t examplelib_core_create() {
auto const *realCore = new examplelib::core();
return static_cast<examplelib_core_t>(realCore);
}
void examplelib_core_destroy(examplelib_core_t core) {
auto const *realCore = static_cast<examplelib::core *>(core);
delete realCore;
}
void examplelib_core_do_something(examplelib_core_t core) {
auto const *realCore = static_cast<examplelib::core *>(core);
realCore->do_something();
}
}
