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">" <<endl<<"<ncx xmlns="http://www.daisy.org/z3986/2005/ncx/" version="2005-1" xml:lang="en-US">"<<endl<<"<head>"<<endl<< "<meta name="dtb:uid" content="BookId"/>"<<endl<< "<meta name="dtb:depth" content="2"/>"<<endl<< "<meta name="dtb:totalPageCount" content="0"/>"<<endl<< "<meta name="dtb:maxPageNumber" content="0"/>"<<endl<< "</head>"<<endl<< "<docTitle><text>藏地密码</text></docTitle>"<<endl<< "<docAuthor><text>何马</text></docAuthor>"<<endl<< "<navMap>"; fout<<"<navPoint class="toc" id=qianyan playOrder="1">"<<endl<< "<navLabel>"<<endl<< "<text>前言</text>"<<endl<< "</navLabel>"<<endl<< "<content src="chapter0.html"/>"<<endl<< "</navPoint>"; for(int i=0;i<menu_name.size();i++) { fout<<"<navPoint class="toc" id=""+menu_name[i]+"" playOrder="1">"<<endl<< "<navLabel>"<<endl<< "<text>"+menu_name[i]+"</text>"<<endl<< "</navLabel>"<<endl<< "<content src="chapter"+to_string(i+1)+".html"/>"<<endl<< "</navPoint>"; } fout<<" </navMap>"<<endl<<"</ncx>"; fout.close(); cout<<"finished ncx"<<endl; } void productOpf(vector<string> & menuName) { fstream fout("./test.opf",fstream::out); fout<<"<package xmlns="http://www.idpf.org/2007/opf" version="2.0" unique-identifier="BookId">"<<endl<< "<metadata xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:opf="http://www.idpf.org/2007/opf">"<<endl<< "<dc:title>电子书标题</dc:title>"<<endl<< "<dc:language>en-us</dc:language>"<<endl<< "</metadata>"<<endl<< "<manifest>"; fout<<"<item id="My_Table_of_Contents" media-type="application/x-dtbncx+xml" href="menu.ncx"/>"<<endl; for(int i=0;i<menuName.size()+1;i++) { fout<<"<item id="item"+to_string(i)+"" media-type="application/xhtml+xml" href="chapter"+to_string(i)+".html"/>"<<endl; } fout<<"</manifest>"<<endl<<"<spine toc="My_Table_of_Contents">"; for(int i=0;i<menuName.size()+1;i++) { fout<<"<itemref idref="item"+to_string(i)+""/>"<<endl; } fout<<" </spine>"<<endl<<"</package>"; fout.close(); cout<<"finished opf"<<endl; }
