示例1: main
int main(int argc, const char* const argv[])
{
// PRINT_ZONES = true;
if(argc < 3)
{
std::cerr << "ERROR: need args. " << std::endl;
std::cerr << "Example: ./cfg huge.cfg 2 " << std::endl;
return 1;
}
const char* const filename = argv[1];
unsigned times;
try
{
times = std::stoul(argv[2]);
}
catch(...)
{
std::cerr << "ERROR: second arg must be a number" << std::endl;
return 1;
}
// Simulates work when randomly accessing strings;
std::string workDummy;
CFG cfg;
for(unsigned t = 0; t < times; ++t)
{
{
Zone zone("parsing");
cfg = CFG(filename);
}
if(!cfg.is_valid())
{
std::cerr << "ERROR: Failed to open or parse file " << filename << std::endl;
return 1;
}
std::vector<std::string> keys;
keys.reserve(cfg.size());
{
Zone zone("iteration");
for(auto& key_value: cfg)
{
keys.push_back(key_value.first);
}
}

for(const std::string& key: keys)
{
const auto found = cfg.find(key);
// assert(key == found->first);
workDummy = key + "=" + found->second ;
}
}
// Test that find() does not accidentally find something not in the config file
assert(cfg.find("<<<NOT=HERE>>>") == cfg.end());
}
// Ensures workDummy is not optimized away
std::cout << workDummy << std::endl;
return 0;
