1# System Capability Encoder and Decoder Tools
2
3SysCap(SystemCapability) encoder and decoder tools common usage scenarios as follow:
4
5APP development: IDE collect APP required SysCap and API verssion as in RPCID encoder input. And IDE will decode PCID to device SysCap list when it imported. This tool is only for use by the IDE, developers will not be used directly.
6
7Main function:
8
91. PCID Encode: Encode SysCap list to PCID.
10
112. PCID Decode: Decode PCID to get system SysCap list.
12
133. RPCID Encode: Encode APP required SysCap list to RPCID.
14
154. RPCID Decode: Decode RPCID to get APP required SysCap list.

36### API
37
38PC tools, no API provided.
39
40### Building Manually
41
42syscap_tool binary building steps as follow:
43
441. Build commands:SysCap tools binary building and installation will be tiggered by SDK compiling procedure. How to build SDK please refer to https://gitee.com/openharmony/build/blob/master/README_zh.md.
45
462. Building cmd should be adjust for host platform as same as SDK compiling, the archive will in corresponding platform directoty.
47
48Note: Ubuntu host only avaiable for windows/linux building, MacOs binary should building on MacOs host.
49
50### Downloading Binary
51
521. Downlaod SDK(recommonded)
53
54Download daily builds(http://ci.openharmony.cn/dailybuilds) which included SDK.

85## Syscap consistency check tool
86
87### Functions and dependencies
88
89The tool provides the following functions:
90
911. Collect syscap fields of all components (or specified components), compare them with arraySyscap in developtools/ syscap_codec/include/syscap_define.h, and output the check results. If they are inconsistent, output the cause of the discrepancy.
922. Collect the syscap fields of all components and compare them with the @syscap property set in *.d.ts in the Interface/sdk-js/api directory. If the check results are inconsistent, output the cause of the inconsistency.
933. Compare syscap attributes in *.d.ts in all interface/ sdK-JS/API directories with arraySyscap in developtools/syscap_codec/include/syscap_define.h. If they are inconsistent,  output the cause of the inconsistency.
94
95### How to use it
96
97This tool is written in Python language and needs to be executed using the Python interpreter.

1# 系统能力编解码工具
2
3系统能力(SystemCapability, 本文中使用SysCap缩写)编解码工具应用场景如下:
4
5应用开发时,IDE会根据应用配置的SysCap和API版本生成描述RPCID(Required Product Compatibility ID)的json文件,并调用编解码工具syscap_tool将该json文件编码成RPCID。另一方面,IDE拿到开发者导入PCID(Product Compatibility ID),使用该工具解码出设备的SysCap集合。该工具仅供IDE使用,对用户不可见。
6
7提供的主要功能:
8
91. PCID编码:对描述SysCap集合的文件编码生成PCID。
10
112. PCID解码:对编码后的PCID文件解码获取SysCap集合。
12
133. RPCID编码:对描述应用所需的SysCap集合的文件编码生成RPCID。
14
154. RPCID解码:对编码后的RPCID文件解码获取应用所需的SysCap集合。
16
175. 编码字符串:将sc后缀形式的PCID/RPCID编码为字符串形式。
18
196. PCID与RPCID比较:查询PCID是否满足RPCID的要求,并输出不满足的地方。

52## API
53PC端工具,不对外提供API。
54
55## PC端编译说明
56syscap_tool PC端可执行文件编译步骤:
571. 编译命令:参考[编译构建](https://gitee.com/openharmony/build/blob/master/README_zh.md)文档,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。
582. 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。
59
60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。
61
62## PC端获取说明
631. 下载sdk获取(建议)
64    通过访问本社区门禁[每日构建](http://ci.openharmony.cn/dailys/dailybuilds)网站,下载最新的ohos-sdk压缩包,并从相应平台的toolchains压缩包中提取syscap_tool。
652. 支持运行环境
66    Windows x86_64/Linux x86_64/Darwin x86_64
67

109# 比较字符串格式的PCID和RPCID,pcid 符合条件返回成功提示,不符合则提示原因。
110syscap_tool -C pcid.txt rpcid.txt
111
112# 功能类似 -C 选项,区别为 -SC 选项为直接输入字符串。
113syscap_tool -sC "pcidstring" "rpcidstring"
114
115# 将字符串格式的 pcid 转为 json 格式,文件名 PCID.json116syscap_tool -Pdsi pcid.txt -o path/
117```
118**说明:**  -o 选项指定输出目录,缺省为当前目录。

121
122### 功能及依赖
123
124本工具主要提供如下功能:
125

1283. 收集所有interface/sdk-js/api目录下的*.d.ts中的syscap属性与developtools/syscap_codec/include/syscap_define.h中的arraySyscap比较,若不一致,输出不一致的原因
129
130### 使用方法
131
132本工具使用python语言编写,需使用python解释器进行执行。
133
134requirements:

139
140使用python3 syscap-check.py -h或python3 syscap-check.py --help查看用法:
141
142```shell
143usage: syscap_check.py [-h] [-p PROJECT_PATH] -t {component_codec,component_sdk,sdk_codec}
144                       [-b [BUNDLES [BUNDLES ...]]]
145
146optional arguments:

151                        the target to be compared
152  -b [BUNDLES [BUNDLES ...]], --bundles [BUNDLES [BUNDLES ...]]
153                        this option will take effect only when the check_target is component_codec. allow multiple
154                        json file. default: all bundle.json file
155```
156
157使用示例:
158
159```shell
160# 检查所有部件的syscap字段与syscap_define.h中的arraySyscap一致性情况
161python3 syscap_check.py -p path_of_openarmony -t component_codec
162
163# 检查指定的部件的bundle.json中的syscap字段与syscap_define.h中的arraySyscap一致性情况,注意,只要当--check_target为component_codec时,--bundles才生效

165
166# 检查所有部件的syscap字段与*.d.ts中的“@syscap”属性集合的一致性情况
167python3 syscap_check.py -p path_of_openarmony -t component_sdk
168
169# 检查*.d.ts中的“@syscap"属性集合与syscap_define.h中的arraSyscap的一致性情况
170python3 syscap_check.py -p path_of_openarmony -t sdk_codec
171```
172
173## syscap_define.h 文件规则
174- 每一个 SyscapNum 枚举值都唯一对应于一个 syscap 字符串。
175- 如果弃用某个 syscap,在对应的枚举值后面注释 "// abandoned" 即可,请勿删除和修改。对应的 syscap 字符串也不需要修改。
176- 添加 syscap,请在 SyscapNum 和 g_arraySyscap 末尾添加相应数据。
177- 数组 g_arraySyscap 按照 SyscapNum 枚举值从小到大排序。
