23. cli¶

23.1. Overview¶

This example mainly introduces how to add a cli (command-line interface).

23.2. Steps for usage¶

编译 customer_app/sdk_app_cli 工程并下载对应的bin文件。
使用 test 命令即可在终端看到打印的 hello world。

23.3. Applications¶

static void cmd_cli(char *buf, int len, int argc, char **argv)
{
    printf("hello world\r\n");
}

const static struct cli_command cmds_user[] STATIC_CLI_CMD_ATTRIBUTE = {
    {"test", "cli test", cmd_cli},
};

int test_cli_init(void)
{
    // static command(s) do NOT need to call aos_cli_register_command(s) to register.
    // However, calling aos_cli_register_command(s) here is OK but is of no effect as cmds_user are included in cmds list.
    // XXX NOTE: Calling this *empty* function is necessary to make cmds_user in this file to be kept in the final link.
    //return aos_cli_register_commands(cmds_user, sizeof(cmds_user)/sizeof(cmds_user[0]));
    return 0;
}

用户在只需在程序中调用test_cli_init()接口之后，就可以在shell中test,就可以打印hello world.如下所示：

#
#
# test
hello world.
