rpclib is looking for maintainers
If you're looking for a similar library with support for JSON-RPC and async operations, check out packio.
rpclib is a RPC library for C++, providing both a client and server implementation. It is built using modern C++14, and as such, requires a recent compiler. Main highlights:
- Expose functions of your program to be called via RPC (from any language implementing msgpack-rpc)
- Call functions through RPC (of programs written in any language)
- No IDL to learn
- No code generation step to integrate in your build, just C++
#include <iostream>
#include "rpc/server.h"
void foo() {
std::cout << "foo was called!" << std::endl;
}
int main(int argc, char *argv[]) {
// Creating a server that listens on port 8080
rpc::server srv(8080);
// Binding the name "foo" to free function foo.
// note: the signature is automatically captured
srv.bind("foo", &foo);
// Binding a lambda function to the name "add".
srv.bind("add", [](int a, int b) {
return a + b;
});
// Run the server loop.
srv.run();
return 0;
}When srv.run() is called, rpclib starts the server loop which listens to incoming connections
and tries to dispatch calls to the bound functions. The functions are called from the thread where
run was called from. There is also async_run that spawns worker threads and returns
immediately.
#include <iostream>
#include "rpc/client.h"
int main() {
// Creating a client that connects to the localhost on port 8080
rpc::client client("127.0.0.1", 8080);
// Calling a function with paramters and converting the result to int
auto result = client.call("add", 2, 3).as<int>();
std::cout << "The result is: " << result << std::endl;
return 0;
}All planned 1.0.0 features are done and tested; the current state is production-ready.
This list is updated as I learn about more people using the library; let me know if you don't want your project listed here.
rpclib builds on the efforts of fantastic C++ projects. In no particular order:
- MessagePack implementation for C and C++ by Takatoshi Kondo (website)
- asio by Christopher Kohlhoff (website)
- cppformat (now renamed
fmtlib, by Victor Zverovich (website) - googletest by Google
- wheels by Martinho Fernandes
