一个从openglapi注册表中提取信息的简单工具。在
注册中心目前位于KhronosGroup组织的github上： https://raw.githubusercontent.com/KhronosGroup/OpenGL-Registry/master/xml/gl.xml
从源设置
克隆repo并输入项目目录。 我们假设用户将设置一个virtualenv。在
pip install -e .
这将在可编辑模式下安装包 意思是你可以继续改变来源 每次更换都要安装。在
如果你真的想安装软件包 不想修改其内容：
^{pr2}$运行测试
我们使用tox来运行覆盖py3.4、py3.6和py3.7的flake9和coverage测试。在
pip install -r tests/requirements.txt # All enviroments tox # Specific enviroments tox -e py35 tox -e py36 tox -e py37 tox -e pep8
正在生成文档
pip install -r docs/requirements.txt python setup.py build_sphinx
注册信息
注册表只是一个巨大的xml文件，通常名为gl.xml，其中包含
有关枚举和函数的信息。然后在

随着版本的进展，必需的和已删除的枚举和函数。在
