Hiredispp is a C++ wrapper around hiredis C library. Hiredis is powerful yet low level client interface for Redis server. Hiredispp aims at providing Redis client interface for standard C++ by leveraging hiredis implementation.

Connection to Redis server is represented by hiredispp::Redis class with type safe implementations of Redis commands

hiredispp::Redis r("localhost");
r.set("foo", "bar");
std::string s = r.get("foo");
boost::int64_t i = r.incr("counter");

Multi-bulk Redis reply is represented by hiredispp::Redis::Reply type

hiredispp::Redis::Reply reply = r.keys("foo:*");
std::vector<std::string> keys;
reply.toVector(keys);	

It is possible to issue dynamically created commands with hiredispp::Redis::Command class

std::vector<std::string> keys;
hiredispp::Redis::Command sunionstore("SUNIONSTORE");
sunionstore << "result" << keys;
r.execute(sunionstore);

Redis pipelining is enabled by pair of begin/end calls in hiredispp::Redis

for (...)
{	
	r.beginSadd(key, member);
}

for (...)
{
	boost::int64_t c = r.endCommand();ng
}

Also it possible to pipeline dynamic commands by executing vector of hiredispp::Redis::Command objects

std::vector<hiredispp::Redis::Command> commands;
for (...)
{	
	commands.push_back(hiredispp::Redis::Command("SADD") << key << member);
}
std::vector<hiredispp::Redis::Reply> replies;
r.execute(commands, replies);

All hiredis library error conditions are thrown as hiredispp::RedisException

try
{
	r.ping();
}
catch (const hiredispp::RedisException& e)
{
	cerr << e.what();
}

After disconnection it is possible to reuse existing hiredispp::Redis object, it will attempt to restore connection.

hiredispp::Redis has corresponding hiredispp::wRedis template instance that supports std::wstring. UNICODE strings are UTF-8 encoded for Redis.
