Executor

A simple shell command executor written in C++, the alternative of subprocess or os.system in Python.

Example

• Simple (congested):

#include <iostream>

#include "executor.hpp"

int main() {
    const char* cmd = "echo \"Hello World!\"";
    std::cout << ubn::executor::executor(cmd)->get()->str();
}

• Async:

#include <iostream>

#include "executor.hpp"

int main() {
    const char* cmd = "ping 8.8.8.8 -c 4";
    auto exec_ftr = ubn::executor::executor(cmd);
    
    // do other things, command executes in the backgroud
    
    std::cout << exec_ftr->get()->str();
}

• Advanced:

#include <iostream>

#include "executor.hpp"

int main() {
    const char* cmd = "ping 127.0.0.1 -c 4";
    auto exec_ftr = ubn::executor::executor<128ul>(ubn::executor::policy::async_wait, cmd);   
    std::cout << exec_ftr->get()->str();
}

Template Parameters

• ubn::exector::policy: async_wait
• ubn::exector::errors: no_implementation, popen_failed
• ubn::exector::buffer_size: 64ul
