【问题描述】：

我想搜索一个正则表达式并用颜色打印它。我使用 boost::sregex_token_iterator 来做到这一点。这是我的代码

    boost::regex re("ab.");
    string s="";
    string buf;
    string infile("retest.txt");
    //string color="green";
    ifstream in(infile.c_str());
    int lcount=0;
    while (getline(in,buf))
    
       boost::sregex_token_iterator p(buf.begin(), buf.end(), re, 0);
       boost::sregex_token_iterator end;
       lcount++;
       cout <<"line : "<<lcount<<endl;
       for (;p != end;++p)
       
           string m(p->first, p->second);
           cout<< m <<endl;
           //cout <<*(p->first)<<endl;
           //cout <<*(p->second)<<endl;
           //unsigned int pos = buf.find(m);
           buf = buf.insert(p->first,"\e[0;32m");
           buf = buf.insert(p->second+m.length()+7,"\e[0m");
       
       cout<<"\n";
       s.append(buf);
       s.append("\n");
     
   in.close();
   cout <<"s is:  "<<s<<endl;
    return 0;
  

但我收到此错误：

的转换

我知道p->first 的类型不是插入函数接受的类型。但我不知道如何将它们相互转换。

【问题讨论】：

风格点，除非你有理由使用后增量，否则总是使用前增量（++lcount）。

你剪掉错误信息了吗？

@alex 感谢您的提示。我是 c++ 新手。 “剪断错误”到底是什么意思？

您是否复制并粘贴了整个错误？好像少了一点。

哦，是的。我剪断了错误输出。它太长了，我认为我提到的部分是最重要的部分。我遇到了这样的错误，每次我都会想出一个解决方案，但这一次有点不同:)

【参考方案1】：

问题可能是您对std::string::insert 的使用。在它的众多重载中，我看不到一个 insert(iterator, string) 版本。

您可能想通过明确说明 char 数组的长度来调用所需的版本：

void insert (iterator p, size_t n, char c)

【参考方案2】：

问题似乎是 boost 被配置为与不同版本的编译器一起使用，而不是您当前使用的编译器。

您能否也添加有关如何编译它的详细信息？

【讨论】：

你说得对，我的 boost 配置有误，我可以通过我的老板解决它！

编译器版本问题只会产生警告，因此可能不是原因。
