1 概述

  在嵌入式开发中，经常会利用命令行交互系统测试功能，本文描述使用C++语言开发的一个命令行交互系统，支持命令注册(C或C++格式)，命令分组，执行命令，显示命令提示。

4.1 实例代码

extern "C" int test1(int argc, char* argv[])
{for(int i = 0; i < argc; i++)std::cout << argv[i] << ",";std::cout << std::endl;return argc;
}class CppcmdTest
{Cmd::CommandManager cmdManager;
public:int test2(Cmd::Args const& args){for(auto arg = args.begin(); arg != args.end(); ++arg)std::cout << *arg << ",";std::cout << std::endl;return args.size();}void run(){cmdManager.registerCommand("test1", "test", test1, "test1 arg1 arg2:"S"arg1:"SS"0x00 - the lane seq 0-1-2-3"SS"0x01 - the lane seq 0-1-3-2"SS"0x02 - the lane seq 0-2-1-3"SS"0x03 - the lane seq 0-2-3-1"SS"0x04 - the lane seq 0-3-1-2"SS"0x05 - the lane seq 0-3-2-1"NLS"arg2SS"0x06 - the lane seq 1-0-2-3"SS"0x07 - the lane seq 1-0-3-2"SS"0x08 - the lane seq 1-2-0-3"SS"0x09 - the lane seq 1-2-3-0"SS"0x0a - the lane seq 1-3-0-2"SS"0x0b - the lane seq 1-3-2-0");cmdManager.registerCommand("test2", "test", HANDLER(CppCmdSuite::test2, this),  "this is a test");cmdManager.showCommands();cmdManager.run("Cmd->");}
};int main(int argc, char *argv[])
{CppcmdTest cmd;cmd.run();return 0;
}

接口说明：

• test1 C格式handler函数
• test2 C++格式Handler函数
• run 注册命名，运行命令行系统
