正規表現で検索して色付きで出力したい。これを行うには、boost::sregex_token_iterator を使用しました。これは私のコードです
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;
}
しかし、私はこのエラーが発生します:
