    lolog::init_logging(argv[0], 5, 200 << 20);
    lolog::set_log_level("Debug");
    lolog::set_std_out(true);

    debug("this is debug");
    info("this is info");
    warn("this is warn");
    error("this is error");
    fatal("this is fatal");
    return 0;
}

Set print source code line

#include "Lolog-Inl.h"
using namespace lolog;

int main(int argc, char* argv[]) {
    lolog::init_logging(argv[0], 5, 200 << 20);
    lolog::set_log_level("Debug");
    lolog::set_std_out(true);
    lolog::set_print_file_line(true);

    debug("this is debug");
    info("this is info");
    warn("this is warn");
    error("this is error");
    fatal("this is fatal");
    return 0;
}

Set color

#include "Lolog-Inl.h"
using namespace lolog;

int main(int argc, char* argv[]) {
    lolog::init_logging(argv[0], 5, 200 << 20);
    lolog::set_log_level("Debug");
    lolog::set_color(true);

    debug("this is debug");
    return 0;
}

Set log file name format

#include "Lolog-Inl.h"
using namespace lolog;

int main(int argc, char* argv[]) {
    lolog::init_logging(argv[0], 5, 200 << 20);
    lolog::set_log_level("Debug");
    lolog::set_color(true);
    lolog::set_log_formate(0);

    debug("this is debug");
