## 1. 编译
```
$ make
```

## 2. 查找
### 2.1 示例
```
#include "src/search.h"

// IP 版本: xdb::ipv4 xdb::ipv6
//    策略: xdb::policy_file xdb::policy_vector xdb::policy_content
//               不缓存           部分缓存           全部缓存
int main() {
    std::string xdb_name = "../../data/ip2region_v6.xdb";
    int         version  = xdb::ipv6;
    int         policy   = xdb::policy_content;
    std::string ip       = "2001:200:124::";

    xdb::search_t s(xdb_name, version, policy);
    std::cout << s.search(ip) << std::endl;
    return 0;
}

// $ g++ src/*.cc 1.cc --- 编译
// $ ./a.out ------------- 测试

## 4. 生成 xdb 文件
### 4.1 生成 xdb 文件
```
$ ./bin/make
生成 ipv4 的 xdb 文件, took: 0.57s
生成 ipv6 的 xdb 文件, took: 1.24s
```

### 4.2 测试正确性
```
# ipv4 --- 只有时间不同
$ diff <(xxd ./ip2region_v4.xdb) <(xxd ../../data/ip2region_v4.xdb)

```

## 5. 原始数据编辑
### 5.1. 使用说明
* 新的IP归属地文件可以包含空行
* 新的IP归属地文件顺序可以乱序, 程序会自动排序
* 新的IP归属地文件顺序可以重叠, 只要无二义性, 程序会自动合并
* 最终的结果会将相邻的且归属地相同的行自动合并
* 以下测试, 原文件使用仓库自带的数据文件, 新文件使用当前目录下的 1.txt
