这家伙很懒，什么也没写！

默认格式化配置：

- 把C99式定义结构体的左左括号放在`Type var = `的那一行

```c
    DevicePinConfigParas pntn[PIN_MAX] = {
        [PIN_RTC_INT] = {"RTC_INT", PIN_MODE_INPUT, 8, GPIO_PIN_RESET},
    };

int app(void)
    {
        DeviceSerialConfigParas paras_2 = {
            .name = "serial2",
            .uart_index = 3,
            .tx_pin = 42,
            .rx_pin = 43,
            .mode = DEVICE_FLAG_INT_RX,
            .auth_flag = DEVICE_FLAG_RDWR,
            .baud_rate = BAUD_RATE_115200,
            .data_bits = DATA_BITS_8,
            .stop_bits = STOP_BITS_1,
            .parity = PARITY_NONE,
            .bit_order = BIT_ORDER_LSB,
        };
    }
    ```

- 放下一行就会缩进

```c
    DevicePinConfigParas pntn[PIN_MAX] =
        {
            [PIN_RTC_INT] = {"RTC_INT", PIN_MODE_INPUT, 8, GPIO_PIN_RESET},
    };

int app(void)
    {
        DeviceSerialConfigParas paras_2 =
            {
                .name = "serial2",
                .uart_index = 3,
                .tx_pin = 42,
                .rx_pin = 43,
                .mode = DEVICE_FLAG_INT_RX,
                .auth_flag = DEVICE_FLAG_RDWR,
                .baud_rate = BAUD_RATE_115200,
                .data_bits = DATA_BITS_8,
                .stop_bits = STOP_BITS_1,
                .parity = PARITY_NONE,
                .bit_order = BIT_ORDER_LSB,
            };
    }
    ```

- 最后一个成员如果没有尾随逗号，右括号就不另起一行：

```c
    DevicePinConfigParas pntn[PIN_MAX] = {
        [PIN_RTC_INT] = {"RTC_INT", PIN_MODE_INPUT, 8, GPIO_PIN_RESET},
    };

int app(void)
    {
        DeviceSerialConfigParas paras_2 = {
            .name = "serial2",
            .uart_index = 3,
            .tx_pin = 42,
            .rx_pin = 43,
            .mode = DEVICE_FLAG_INT_RX,
            .auth_flag = DEVICE_FLAG_RDWR,
            .baud_rate = BAUD_RATE_115200,
            .data_bits = DATA_BITS_8,
            .stop_bits = STOP_BITS_1,
            .parity = PARITY_NONE,
            .bit_order = BIT_ORDER_LSB};
    }
    ```

这可以用于长数组的美化，例如

```c
    // 没有尾随逗号，格式化后每行的排布不变
    int array1[] = {0x00,0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
                    0x08, 0x09,0x0a, 0x0b,0x0c,0x0d, 0x0e, 0x0f};
    
    // 有尾随逗号，格式化后每项展开成一行
    int array2[] = { 1,2,    3,4, 5,6,7, 8,};
    ```

格式化后：

```c
    int array1[] = {0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07,
                    0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d, 0x0e, 0x0f};
    
    int array2[] = {
        1,
        2,
        3,
        4,
        5,
        6,
        7,
        8,
    };
    ```
