介绍

开源许可证兼容性分析工具,基于结构化的许可证信息和具体场景的依赖行为与构建设置,对目标中引入的开源许可证进行兼容性分析。

尽管我们会尽力确保该工具的准确性和可靠性,但本项目的检查结果不构成任何法律建议。使用者应自行审查和判断,以确定所采取的行动是否符合法律法规以及相关许可证的规定。

注意:本项目当前仍处于早期版本,相关结果的准确性未进行验证,且迭代过程中各模块接口将会发生较大变化。

快速开始

当前版本仅支持面向 OpenHarmony 的兼容性检测,欢迎使用面向 OpenHarmony 全量源码仓的一键检测脚本 LictOneClick

安装教程

  1. 确保已经安装 python 3.11^
  2. clone 仓库
  3. 进入仓库根目录 pip install .

如果安装过 lict 版本,请先卸载旧版

使用说明

确保工具安装后,终端输入指令 liscopelens --help

usage: liscopelens [-h] [-c CONFIG] {sbom,cpp} ...

部件兼容性分析工具

positional arguments:
  {sbom,cpp}
    sbom                Software Bill of Materials (SBOM) parser, this parser only support for OH sbom format.
    cpp                 This parser is used to parse the C/C++ repository and provide an include dependency graph
                        for subsequent operations

options:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        配置文件路径

分析代码仓库的兼容性(请确保存在gn工具或者gn解析文件)

  1. 获取 OpenHarmoy 源码
  2. 安装 OpenHarmony 编译构建工具执行 ./build.sh --product-name {设备形态} --gn-flags="--ide=json" --gn-flags="--json-file-name=out.json"
  3. 确保在源码根目录下具有OpenHarmony/out/{设备形态}/out.json 存在
  4. 使用 Scancode 扫描 OpenHarmony 许可证
  5. 执行 liscopelens 进行兼容性扫描
    liscopelens cpp --gn_file OpenHarmony/out/{设备形态}/out.json --scancode-file path/to/scancode-res.json --output ./output
  6. 查看 output/results.json 或则借助审查工具

其他参数可以,查看帮助 liscopelens cpp -h,解释如下:

usage: liscopelens cpp [-h] (--gn_tool GN_TOOL | --gn_file GN_FILE)
                (--scancode-file SCANCODE_FILE | --scancode-dir SCANCODE_DIR) [--rm-ref-lang] [--save-kg]
                [--ignore-unk] [--out-gml OUT_GML] [--echo] [--out-echo OUT_ECHO]

options:
  -h, --help            show this help message and exit
  --gn_tool GN_TOOL     the path of the gn tool in executable form
  --gn_file GN_FILE     the path of the gn deps graph output file
  --scancode-file SCANCODE_FILE
                        The path of the scancode output in json format file
  --scancode-dir SCANCODE_DIR
                        The path of the directory that contain json files
  --rm-ref-lang         Automatically remove scancode ref prefix and language suffix from spdx ids
  --save-kg             Save new knowledge graph after infer parse
  --ignore-unk          Ignore unknown licenses
  --out-gml OUT_GML     The output path of the graph
  --echo                Echo the final result of compatibility checking
  --out-echo OUT_ECHO   The output path of the echo result
