此工具可以将 html 文件转换为 epub 格式的电子书。它根据html文件中的特定标签，将其拆分为章节，并自动生成目录等信息。
This tool helps to create epub books from html files. It split the html file into chapters according to special tags in the file and generate the TOC automatically.
这些特定标签被称为“拆分点”，有“标题标签(<h1>, <h2>,...<h6>)”和“章节标签(class 属性包含 makeepub-chapter 的标签)”两种。章节标签主要在需要对章节标题进行修饰时使用，如在章节标题前插入横幅图片等。
The special tags are call "split point", including two kinds of tags: "header tags(<h1>, <h2>, ... <h6>)" and "chapter tags (tag's class attribute contains makeepub-chapter )". Chapter tags is useful if chapter title decoration is required, for example: add a banner image before the title.
每个拆分点有“级别”和“标题”两个属性，分别对应目录中的级别和标题。其中级别是一个0到6之间的整数，但0级拆分点只用于文件拆分，不会出现在目录中。
Every split point has two properties: 'level' and 'title', they are mapped to the level and title properties of a TOC item. 'Level' is an integer betwwen 0 and 6, but level 0 split point is only for file split, will not be used for generate TOC.
此工具支持批处理模式，可一次性转换生成多个epub文件。它还支持打包、解包epub文件，合并html文件或文本文件；还可以作为一个web服务器，转换上传的zip文件为epub文件。
The tool support batch mode which can generate multiple epub books in one execution. It also support pack/extract an epub book, merge html/text files. And can be used as a web server to convert an uploaded zip file to an epub book.

makeepub <VirtualFolder> [OutputFolder]
处理 VirtualFolder 中的文件，生成epub，并保存到 OutputFolder 中。在VirtualFolder中，必须有以下三个文件：
Process files in VirtualFolder, generate epub file and save it to OutputFolder . The 3 files below 3 are mandatory and must exist in VirtualFolder:
- book.ini 配置文件，用于指定书名、作者等信息(configuration file to specify book name, author and etc.)
- book.html 书的正文(The content of the book)
- cover.png or cover.jpg or cover.gif 封面图片文件(The cover image of the book)
请 务必 使用 UTF-8 编码保存前两个文件，否则程序可能不能正确处理。
The first 2 files MUST stored in UTF-8 encoding, otherwise, the tool may not able to process them correctly.
除以上文件外，其它书籍需要的文件，如层叠样式表（css），图片等也应保存到此文件夹中。如果文件内容是文本，建议也使用 UTF-8 编码保存。
Besides the 3 files above, other files required by the book, like sytle sheet (css) and images, are also required to be put into the folder. And if the content of a file is text, it is also recommend to store it in UTF-8 encoding.
下面是对主要文件的格式的简单介绍，更多信息请参考example文件夹中的示例。
Below is a brief introduction of the format of the mandatory files, more information please refer to the examples in the example folder.
此文件基于通用的ini文件格式，以'='开始的行将被合并到上一行，以'#'开始的行将被视为注释，并被忽略。
This file is based on the common INI file format, line start with '=' will be joint to previous line, and line start with '#' will be regard as comment and ignored.
这个文件包含三个节， book 、 split 和 output，book节指定书籍信息，split节指定如何进行章节拆分，output节指定输出文件信息。下面的列表将介绍其中每一个选项的作用。
This file contains three sections: book, split and output. section book is for the book information, split determines how chapters are split, and section output is for the output file. The below list explains the usage of each option.
-
Book节(Section Book)
- name: 书名，如果没有提供会导致程序输出一个警告信息(Name of the book, if not specified, the tool will generate a warning)
- author: 作者，如果没有提供会导致程序输出一个警告信息(Author of the book, if not specified, the tool will generate a warning)
- id: 书的唯一标识，在正规出版的书中，它应该是ISBN编号，如果您没有指定，程序将随机生成一个(The unique identifier, it is the ISBN for a published book. If not specified, the tool will generate a random string for it.)
- publisher: 出版社(The publisher of the book.)
- description: 书籍简介(A brief introduction of the book.)
- language: 语言，默认 zh-CN ，即简体中文(Language of the book, zh-CN by default, that's Chinese Simplified.)
- toc: 一个 1 到 6 之间的整数，用于指定目录的粒度，默认为 2，即只生成1、2两级拆分点对应的目录(An integer between 1 and 6, specifis how to TOC is generated. Default value is 2, which means the TOC is based on level 1 and level 2 split points)
-
Split节(section Split)
- AtLevel: 一个 0 到 6 之间的整数，用于指定章节拆分的粒度，默认为 1，即只根据1级拆分点拆分章节(An integer between 0 and 6, specifis how to split the html file into chapters. Default value is 1, which means the split is based on the level 1 split points)
- ByHeader: 一个 1 到 7 之间的整数。如果一个“标题标签”拆分点的级别小于此选项的值，那么这个拆分点将被忽略。默认值是1，即不忽略任何“标题标签”拆分点。(An integer between 1 and 7. A "header" split point will be ignored if its level property is smaller than this value. Default is 1 which means no "header" split point will be ignored.)
-
Output节(Section Output)
- path: 输出epub文件的路径。如果没有指定，程序会产生一个警告且不会生成任何文件(The output path of the target epub file. If the path is not specified, the tool will generate a warning and no file will be created)
下面是book.ini的一个例子。
Below is an example for book.ini.
[book]
name=My First eBook
author=Super Man
id=ISBN XXXXXXXXXXXX
publisher=My Own Press
description= 这是本书的简介，它占用了多行。 This is the description
= of the book, and it has more than one line.
language=zh-CN
toc=2
[split]
AtLevel=1
ByHeader=1
[output]
path=d:\MyBook.epub
它是一个标准的html文件，根据 split 节的设置，程序会将此文件拆分成章节文件，根据 toc 设置生成书籍目录。<body>标签之前的内容会被复制到每个章节文件的开头。
This is a standard html file. The tool will split this file into chapter files based on split setting, and generate TOC based on the toc setting. Content before <body> tag will be copied to the beginning of each chapter file.
如果其中的某个 img 标签符合以下情况，它将会全屏显示 (An image is displayed as full screen if its img tag meet all below conditions):
- 打开了多看扩展 (DuoKan externsion is enabled)
- img 标签的父级是 body 标签 (The parent of img tag is body tag)
- img 的 class 属性包含 duokan-fullscreen (The value of the class property of the img tag contains duokan-fullscreen )
一个图片文件，它将被用来生成封面。这个文件可以是cover.png、cover.jpg和cover.gif中的任意一个，如果存在多个，如同时有cover.png和cover.jpg，那么程序会随机使用其中一个生成封面。
An image file which will be used to create the book cover. It can be 'cover.png', 'cover.jpg' or 'cover.gif', if more than one file exists (for example: both 'cover.png' and 'cover.jpg'), the tool will select one randomly.
封面文件的名字是cover.html，所以请勿使用这个文件名，否则程序的行为将是未知的。
The file name of the cover page is 'cover.html', please don't use this name for any other purpose, otherwise the behavior of this tool is not defined.
拆分点的使用遵循以下规则，具体使用方法请参考 example 文件夹中的例子。
Below are the rules of split point, please refer to the example folder for examples.
- 所有拆分点都必须是 body 标签的直接子标签。(All split point MUST be the direct child of the body tag.)
- 默认情况下，“标题标签”都是拆分点，其“级别”是这个标签的级别，“标题”是这个标签的内容。 (By default, all "header tags" are split points, their "level" are the level of the tags and "title" are the content of these tags.)
- “标题标签”的“标题”也可以通过 data-chapter-title 属性指定，这种情况下，目录中的标题和正文中的标题将不一样。("Title" can also be specified by data-chapter-title attribute, in this case, the chapter will have different title in TOC and content.)
- 如果一个标题标签的 class 属性包含 makeepub-not-chapter ，那么它不是拆分点。(A header tag is not split point when its class attribute contains makeepub-not-chapter .)
- 任何标签，如果它的 class 属性包含 makeepub-chapter ，那么它是一个“章节标签”拆分点。(A tag is a "chapter tag" split point if its class attribute contains makeepub-chapter .)
- “章节标签”拆分点的“级别”和“标题”可以由 data-chapter-level 和 data-chapter-title 属性指定。(The "level" and "title" of a "chapter tag" can be specified by the "data-chapter-level" and "data-chapter-title" attributes.)
- 如果一个“章节标签”没有 data-chapter-level 属性，那么它的“级别”和“标题”由后续的（包括此标签）第一个“标题标签”决定，同时这个“标题标签”失效。但在找到所需的“标题标签”之前，如果出现了其他“章节标签”，则此“章节标签”失效。(If a "chapter tag" does not have data-chapter-level attribute, its "level" and "title" will be determined by the first "header tag" after it (or itself, if it is a "header tag" also), and the "header tag" will be ignored. But, if another "chapter tag" is found before the required "header tag", this "chapter tag" will be ignored.)
- “章节标签”的优先级高于“标题标签”，即如果一个标签既是“章节标签”又是“标题标签”，它将被作为“章节标签”处理。(The priority of "chapter tag" is higer than "header tag", so if a tag is both "chapter tag" and "header tag", it is regarded as "chapter tag".)
- 0级拆分点只用于文件拆分，不生成目录。(Level 0 split point is only for file split, will not be used for generate TOC.)
- 级别小于 ByHeader 的“标题标签”拆分点会全部被忽略。("Header tag" split points whose level are smaller than ByHeader will be ignored.)
- 级别大于 toc 的拆分点不会生成目录。(Split points whose level are larger than toc will not appear in TOC.)
- 级别大于 AtLevel 的拆分点不会造成文件拆分。(File split will not happen on split points whose level are larger than AtLevel .)
- 为尽量避免拆分出来的文件只包含章节标题，即使某个拆分点按照 AtLevel 选项应该被拆分，如果它和它的上级拆分点之间没有任何正文，它也不会被拆分。(To avoid a chapter file only has a chapter title, file split will not happen on a split point if there's no text between the split point and its parent split point, no matter what the value of option AtLevel is.)
输出文件的路径取决于 book.ini 中 output 节的 path 选项，命令行中的 OutputFolder 参数，以及程序的当前工作文件夹。
The path of the out file is determined by the path option of section output in book.ini, argument OutputFolder in command line, and the current working folder of the tool.
如果缺少path选项，不会生成任何文件。
No file will be create if there's no option path.
如果没有OutputFolder参数，且path是相对路径，输出文件路径是相对于当前工作文件夹的path。
If argument OutputFolder is not specified, and path is relative, the output file path will be path relative to the current working folder.
如果没有OutputFolder参数，且path是绝对路径，输出文件路径是path。
If argument OutputFolder is not specified, and path is absolute, the output file path is path.
如果指定了OutputFolder，文件会被保存在OutputFolder，文件名是path中的文件名部分。
If OutputFolder is specified, output file will be save at OutputFolder, and file name is the 'file name' in path.
makeepub -b <InputFolder> [OutputFolder] [-epub2] [-noduokan]
makeepub -b <BatchFile> [OutputFolder] [-epub2] [-noduokan]
批处理模式，相当于对InputFolder中的(或BatchFile列出的)每个VirtualFolder folder，调用：
Batch mode, is equal to: for each VirtualFolder folder in InputFolder (or listed in *BatchFile), call:
makeepub folder [OutputFolder] [-epub2] [-noduokan]
makeepub -p <VirtualFolder> <OutputFile>
将VirtualFolder中的文件打包成一个EPUB文件，保存为OutputFile。
Pack the files in VirtualFolder into an EPUB and save it as OutputFile.
makeepub -e <EpubFile> <OutputFolder>
将EpubFile解包到OutputFolder中。
Extract EpubFile to folder OutputFolder.
makeepub -mh <VirtualFolder> <OutputFile>
makeepub -mt <VirtualFolder> <OutputFile>
按文件名升序合并VirtualFolder中的文件，并将合并结果保存为OutputFile。合并模式可以使html模式(-mh)或文本(-mt)。
Sort files in VirtualFolder in ascend order by file name, merge them, and save the merge result as OutputFile. The merge mode can be html(-mh) or text(-mt).
文本模式是简单的将文件内容连接在一起，Html模式会分析文件，只保留一份文件头(<body>之前的部分)和文件尾(</body>之后的部分)。
text mode is simply merge file content one by one. html mode will analysis the file to keep only one copy of file header (content before <body>) and file footer (content after </body>).
makeepub -s [Port]
以Web服务器形式运行，处理用户上传的zip文件，生成EPUB文件，供用户下载。
Run as a web server, process the user uploaded zip file, and generate the EPUB file for user to download.
如果不需要此功能，可将其删除以减小可执行文件的体积。
