I always like to read novels on the kindle. The kindle doesn't hurt my eyes. It can also help control the time of playing mobile phones. But it's a headache to read the online novels in the format of txt on the kindle. Such novels have no catalogue on the kindle, and they are very long. So I always wanted to add a catalog. So there is this article.
In this case, to add a directory, you need to convert a novel in txt format to mobi format. With the help of kindlegen, some of its syntax will not be explained here in detail. Here is a schematic diagram, as follows:
The general idea is to generate html, ncx and opf files. The code is as follows:
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?"Preface":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>Tibetan code</text></docTitle>"<<endl<< "<docAuthor><text>He ma</text></docAuthor>"<<endl<< "<navMap>"; fout<<"<navPoint class=\"toc\" id=qianyan playOrder=\"1\">"<<endl<< "<navLabel>"<<endl<< "<text>Preface</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>EBook title</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; }
