利用VS根据文件目录结构创建C++工程自己简单实现的方法

相信程序员都有过这样的经历。

一些开源的C、C++代码库大多数是在linux下面开发的。为了能在windows下面用VS方便查看代码，可以利用VS根据已有代码来创建C++项目。简单步骤如下：

第一步：打开VS，点击“文件”菜单，在弹出菜单选择“新建”，最后选择“从现有代码创建项目”;



第二步：根据向导创建VC++项目，



找到已有代码的文件，添加进来



使用VS来生成项目，项目类型这里是控制台应用，最后点击完成就可以生成项目了。



最后生成的项目结构目录如下，一点层次结构都没有了：



第三步：自己写代码来实现自动建立目录结构，这里贴上自己写的代码：

#include <stdio.h>
#include "tinyxml/tinyxml.h"
#include <iostream>
#include <vector>
#include <set>
using namespace std;

#ifdef WIN32
//guid
#include <objbase.h>
#else
#include <uuid/uuid.h>
#endif

GUID CreateGuid()
{
GUID guid;
#ifdef WIN32
CoCreateGuid(&guid);
#else
uuid_generate(reinterpret_cast<unsigned char *>(&guid));
#endif
return guid;
}

std::string GuidToString(const GUID &guid)
{
char buf[64] = { 0 };
#ifdef __GNUC__
snprintf(
#else // MSVC
_snprintf_s(
#endif
buf,
sizeof(buf),
"{%08X-%04X-%04X-%02X%02X-%02X%02X%02X%02X%02X%02X}",
guid.Data1, guid.Data2, guid.Data3,
guid.Data4[0], guid.Data4[1],
guid.Data4[2], guid.Data4[3],
guid.Data4[4], guid.Data4[5],
guid.Data4[6], guid.Data4[7]);
return std::string(buf);
}

void subDir(vector<string>& arr,string str,char sp)
{
arr.push_back(str);
for (size_t pos = str.find_last_of(sp); pos != string::npos; pos = str.find_last_of(sp))
{
str = str.substr(0, pos);
arr.push_back(str);
}
}

int main()
{
set<string> OldDirset;
set<string> NewDirset;
char tmp[256];

cout << "输入文件名！" << endl;
cin >> tmp;
string filepath = tmp;
TiXmlDocument doc(filepath.c_str());

bool b=doc.LoadFile();
if (!b) {
printf("Error: 加载文件失败！！");
}
printf("文件加载成功!\n");
//std::cout<<doc.Value()<<std::endl;
TiXmlElement* project= doc.FirstChildElement();	//第一个Project元素
//cout << project->Value() << project->Attribute("xmlns")<<endl;
//cout << project->FirstChild()->NextSibling()->Value();//获取第二个
TiXmlElement* FirstItemGroup = project->FirstChildElement();

//查找已有信息
{
TiXmlElement* Filter = FirstItemGroup->FirstChildElement();
//cout << Filter->Value() << endl;
for (; Filter != NULL; Filter = Filter->NextSiblingElement())
{
string dir = Filter->Attribute("Include");
OldDirset.insert(dir);
}
}
//查找未添加的
TiXmlElement* ItemGroup = FirstItemGroup->NextSiblingElement();
for (int i=0; ItemGroup != NULL && i<2;ItemGroup=ItemGroup->NextSiblingElement(),i++)
{
TiXmlElement* ClCompile = ItemGroup->FirstChildElement();
for (; ClCompile != NULL; ClCompile = ClCompile->NextSiblingElement())
{
string dir = ClCompile->Attribute("Include");
TiXmlElement* Filter = ClCompile->FirstChildElement();
dir = dir.substr(0, dir.find_last_of('\\'));
Filter->FirstChild()->ToText()->SetValue(dir.c_str());
//cout << dir.c_str() << endl;
vector<string> arr;
subDir(arr, dir, '\\');
for (int i = 0; i < arr.size(); i++)
{
if (OldDirset.insert(arr[i]).second)
{
NewDirset.insert(arr[i]);
}
}
}
}

//add
set<string>::iterator itset = NewDirset.begin();
for (; itset != NewDirset.end(); itset++)
{
GUID guid = CreateGuid();
//cout << GuidToString(guid).c_str() << endl;
TiXmlElement Filter("Filter");
Filter.SetAttribute("Include", itset->c_str());
TiXmlElement UniqueIdentifier("UniqueIdentifier");
TiXmlText text(GuidToString(guid).c_str());
UniqueIdentifier.InsertEndChild(text);
Filter.InsertEndChild(UniqueIdentifier);
FirstItemGroup->InsertEndChild(Filter);
}

//filepath += ".new";
doc.SaveFile(filepath.c_str());
cout << "修改完成！" << endl;
return 0;
}

代码中有用到tinyxml来解析xml文件，tinyxml是一个比较简单的解析xml的开源库。

需要解析的xml文件就是创建项目时生成的redis-3.0.3.vcxproj.filters文件(可以用文本编辑器打开)。这个文件就是存放目录结构的。

未修改前的内容如下：

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

编译运行上面的C++代码，运行后需要输入改xml文件的绝对路径，最后完成转换的结果：

重新打开项目之后的结果如下：



大功告成！！！
