初次接手一个大工程时, 往往因为复杂的项目依赖而遇到各种编译问题, 同时如果能图形化其中的依赖关系对理解整个项目有莫大的帮助, 就像能从山顶俯瞰大陆的感觉. 本文即着重于实现此功能.
下面给出了两个Project, 其中project1的GUID为E37ACEB3-9187-43F7-AA78-000000000001
project2的GUID为E37ACEB3-9187-43F7-AA78-000000000002,
postProject部分给出了依赖关系: project2依赖于project1
Project("{2150E333-AAAA-42A3-9474-1A3956D46DE9}") = "project1", "project1.vcxproj", "{E37ACEB3-9187-43F7-AA78-000000000001}"
EndProject
Project("{2150E333-AAAA-42A3-9474-1A3956D46DE9}") = "project2", "project2.vcxproj", "{E37ACEB3-9187-43F7-AA78-000000000002}"
ProjectSection(ProjectDependencies) = postProject
{E37ACEB3-9187-43F7-AA78-000000000001} = {E37ACEB3-9187-43F7-AA78-000000000001}
EndProjectSection
EndProjectPython正则表达式解析project: r'Project[^=]+=\s*"([^"]+)"\s*,\s*"([^"]+)"\s*,\s*"\{([^"]+)\}"'
group(1)为project_name, group(2)为project_vcproj, group(3)为GUID
Python正则表达式解析postProject: r'\{([\w-]+)\}\s=\s\{([\w-]+)\}'
group(1)应该等于group(2), 都是依赖的项目的GUID.

还有一种依赖关系保存在project文件里，形式如下：
<ProjectReference Include="..\MsgCreator\MsgCreator.vcxproj">
<Project>{d3eada85-50f9-4a1d-a2f7-18612358b436}</Project>
<ReferenceOutputAssembly>false</ReferenceOutputAssembly>
</ProjectReference>表示当前工程依赖MsgCreator. vcxproj其实是个XML文件，直接用BeautifulSoup打开查找<Project>项即可。
