C++ (Cpp) PARSE_INTEGER Examples

Example #1

File: map.cpp Project: icyflame/software

map load_map(void) {
  char* dir = getenv("CUAUV_SOFTWARE");
  if (dir == nullptr) throw s::runtime_error("cuauv::conf::load_map: CUAUV_SOFTWARE must be set to the root of the software repository with a trailing slash.");

  char* locale = getenv("CUAUV_LOCALE");
  if (locale == nullptr) throw s::runtime_error("cuauv::conf::load_map: CUAUV_LOCALE must be defined corresponding to a config file in the conf directory.");

  s::string filename = s::string(dir) + "conf/" + s::string(locale) + ".conf";
  s::ifstream ifs(filename);
  if (!ifs) throw s::runtime_error("cuauv::conf::load_map: Locale file does not exist or cannot be opened.");
  
  Json::Value root;
  Json::Reader reader;
  if (!reader.parse(ifs, root)) throw s::runtime_error("cuauv::conf::load_map: Locale file cannot be parsed.");

  PARSE_OBJECTS(objects);
  PARSE_INTEGER(num_particles);

  map m {
    objects,
    num_particles
  };
 
  return m;
