#### 软件架构
软件架构说明
## 简介<a name="section662115419449"></a>
SysCap编解码工具的应用场景：
1.设备开发时，设备厂商对OS不见进行拼装后，编译构建生成Syscap列表，厂商ID和API版本信息作为Syscap编解码工具的输入，生成PCID。
2.应用开发时，IDE根据应用配置的Syscap和API版本生成RPCID。开发者导入PCID时，使用Syscap编解码工具解码出设备的Syscap集合。
3.应用分发时，应用市场使用Syscap工具对应用RPCID和设备的PCID进行解码。
4.应用安装时，包管理使用Syscap工具解码应用需要的Syscap集合。
## 架构<a name="section15908143623714"></a>
SysCap编解码工具主要有两部分组成：
1. syscap_tool部分：运用于应用开发场景，供IDE使用，用于编码生成RPCID和解码PCID
2. syscap_tool_shared部分：用于设备开发、应用安装等场景，完成RPCID和PCID的编解码。

### pc端编译说明<a name="section129654513262"></a>
#### 安装教程
syscap_tool pc端可执行文件编译步骤：
1. xxxx
2. xxxx
3. xxxx
1. 编译命令：编译sdk命令 请参考https://gitee.com/openharmony/build/blob/master/README_zh.md 仓编译sdk说明， 执行其指定的sdk编译命令来编译整个sdk， syscap_tool会被编译打包到里面。
#### 使用说明
2. 编译：在目标开发机上运行上面调整好的sdk编译命令， 正常编译syscap_tool会输出到sdk平台相关目录下； 注意： ubuntu环境下只能编译windows/linux版本工具，mac版需要在macos开发机上编译。
1. xxxx
2. xxxx
3. xxxx
### pc端获取说明<a name="section129654513263"></a>
#### 参与贡献
[1.下载sdk获取(建议)](#section161941989591)
```
通过访问本社区网站下载dailybuilds或正式发布的sdk压缩包，从中根据自己平台到相应的目录toolchain下解压提取
```
1. Fork 本仓库
2. 新建 Feat_xxx 分支
3. 提交代码
4. 新建 Pull Request
[2.自行编译](#section161941989592)
编译请参考上面单独小节，本项目仓prebuilt目录下不再提供预制
#### 特技
[3.支持运行环境](#section161941989593)
linux版本建议ubuntu 18.04以上 64位，其他相近版本也可。
### 命令帮助<a name="section129654513265"></a>
使用./syscap_tool -h或者./syscap_tool --help查看：
./syscap_tool -R/P -e/d -i filepath [-o outpath]
-h, --help : how to use
-R, --RPCID : encode or decode RPCID
-P, --PCID : encode or decode PCID
-e, --encode : to encode
-d, --encode : to decode
-i filepath, --input filepath : input file
-o outpath, --input outpath : output path
1. 使用 Readme\_XXX.md 来支持不同的语言，例如 Readme\_en.md, Readme\_zh.md
2. Gitee 官方博客 [blog.gitee.com](https://blog.gitee.com)
3. 你可以 [https://gitee.com/explore](https://gitee.com/explore) 这个地址来了解 Gitee 上的优秀开源项目
4. [GVP](https://gitee.com/gvp) 全称是 Gitee 最有价值开源项目，是综合评定出的优秀开源项目
5. Gitee 官方提供的使用手册 [https://gitee.com/help](https://gitee.com/help)
6. Gitee 封面人物是一档用来展示 Gitee 会员风采的栏目 [https://gitee.com/gitee-stars/](https://gitee.com/gitee-stars/)
