enum LogLevel { INFO, WARN, ERROR }

template log(LogLevel level)
{
    void log(Args...)(Args args, string fn = __FUNCTION__, string file = __FILE__, size_t line = __LINE__)
    {
        writeln(Clock.currTime(), " [", level, "] ", file, '(', line, "): ", fn, ": ", args);
    }
}

alias info = log!(LogLevel.INFO);
alias warn = log!(LogLevel.WARN);
alias error = log!(LogLevel.ERROR);


//不再需要插件/样板代码

void main(string[] args)
{
    info("hello", "world");
    warn("i am ", "number ", 1);
    error(true);
    log!(LogLevel.INFO)("manual call");
}
