This repository provides a wrapper around the C library hiredis. Instead of using the C API, you can use an wrapper object instead which will automatically clean the C objects, and provides simple function for the most used commands.

This code is designed for one of my project so there is not all the features you would expect from a real C++ redis client. However, the C++ wrapper still provides a way to use directly the C object so you will have access to all the features from hiredis.

The C library hiredis is used. Because currently there are compilation errors with sdc and g++ (see redis/hiredis#428, redis/hiredis#412). I forked the repo with a fix in the meantime. https://github.com/SnoozeTime/hiredis-cpp

Json cpp is also used for serialization in the examples but it is not necessary for the core library.

• Add unit tests
• More features

First, create a RedisInterface object. It will take the hostname, port of the redis server, and a timeout (= 0 for no timeout) for the connection to the server.

RedisInterface redis("127.0.0.1", 6379, 1500);

Then, you can do the following basic operations:

• Get a key
• Set a key
• push value(s) to a list (left or right)
• pop a value from a list (left or right)
• pop or block if the list is empty.
• Select a database

/*
    Return "" if no value
*/
std::string value = redis.get("key");

bool success = redis.set("key", "value");

/*
    You can push 1 to n values to a list
*/
bool success = redis.lpush("mylist", "1");
success = redis.rpush("mylist", "1", "abcv", "another value");

/*
    lpop for non blocking left pop and blpop for blocking left pop
*/
unsigned int timeout = 1; // 1 second
std::string value = redis.blpop("thekey", timeout);

// If using multiple keys, timeout comes first
std::string value = redis.blpop(0, "list1", "list2");

// and so on
