利用kindlegen实现txt格式小说转换为mobi格式小说（C++实现）

　　一直以来喜欢在kindle上看小说，kindle不伤眼，也可以帮助控制玩手机的时间。但在kindle上看txt格式的网络小说就很头疼了，这类小说在kindle上是没有目录的，而且篇幅巨长。所以一直以来我都想加上目录。于是就有了这篇文章。

　　在这里，要想加上目录，就要将txt格式的小说转换为mobi格式。我借助了kindlegen，它的一些语法不再这里详说了，给个示意图，如下：

　　总思路就是生成html和ncx、opf文件，代码如下：

　　1.read.cpp

#include <iostream>
#include <string>
#include <fstream>
#include <vector>
#include <regex>
#include <windows.h>
#include "productHtml.h"

using namespace std;

int main(int argc,char * * argv)
{
    fstream fin(argv[1],fstream::in);
    string test="";
    vector<string> vec_menu;
    vector<string> vec_text;
    string rs="^[0-9]";
    regex expression(rs);
    smatch wm;
    string str_text="<p>";

    while(getline(fin,test))
    {
        if (regex_search (test,wm,expression)) {
            vec_menu.push_back(test);
            //cout<<str_text<<endl;
            str_text+="</p>";
            vec_text.push_back(str_text);
            str_text="<p>";
        }
        else
        {
            str_text+=test;
            str_text+="<br/>";
        }
    }
    vec_text.push_back(str_text);
    cout<<vec_menu.size()<<" "<<vec_text.size()<<endl;
    for(int i=0;i<vec_text.size();i++)
    {
        /*
        cout<<vec_menu[i]<<endl;
        cout<<vec_text[i+1]<<endl;
        */
        string str=vec_text[i];
        string str_name=i==0?"前言":vec_menu[i-1];
        productHtml(str_name,str,i);
    }
    productNcx(vec_menu);
    productOpf(vec_menu);
    cout<<"finished"<<endl;
    fin.close();

    int ret=(int)ShellExecute(NULL,"open","kindlegen.exe","test.opf",NULL,SW_SHOWNORMAL);
    cout<<"ret: "<<ret<<endl;
    return 0;
}

2.productHtml.h

#include <iostream>
#include <string>
#include <fstream>

using namespace std;

void productHtml(string str_name,string str_text,int no)
{
    string fileName="./chapter"+to_string(no)+".html";
    fstream fout(fileName,ios::out);
    fout<<"<html>"<<endl<<"<head>"<<endl<<"<meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\">"
        <<endl<<"<link rel=\"stylesheet\" type=\"text/css\" href=\"online.css\">"
        <<endl<<"</head>"<<endl<<"<body>";
    fout<<"<title>"<<str_name<<"</title>"<<endl<<str_text;
    fout<<" </body>"<<endl<<"</html>";

    fout.close();
}

void productNcx(vector<string> & menu_name)
{

    fstream fout("./menu.ncx",ios::out);
    fout<<"<?xml version=\"1.0\" encoding=\"UTF-8\"?>"<<endl<<"<!DOCTYPE ncx PUBLIC \"-//NISO//DTD ncx 2005-1//EN\" \"http://www.daisy.org/z3986/2005/ncx-2005-1.dtd\">"

    fout.close();
