How to generate an EPUB file on Fedora
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
It is becoming more popular to read content on smartphones. Every phone comes with its own ebook reader. Believe or not, it is very easy to create your own ebook files on Fedora.
|
||||
|
||||
This article shows two different methods to create an [EPUB][2]. The epub format is one of the most popular formats and is supported by many open-source applications.
|
||||
|
||||
Most people will ask “Why bother creating an EPUB file when PDFs are so easy to create?” The answer is: “Have you ever tried reading a sheet of paper when you can only see a small section at a time?” In order to read a PDF you have to keep zooming and moving around the document or scale it down to a small size to fit the screen. An EPUB file, on the other hand, is designed to fit many different screen types.
|
||||
|
||||
### Method 1: ghostwriter and pandoc
|
||||
|
||||
This first method creates a quick ebook file. It uses a Markdown editor named [ghostwriter][3] and a command-line document conversion tool named [pandoc][4].
|
||||
|
||||
You can either search for them and install them from the Software Center or you can install them from the terminal. If you are going to use the terminal to install them, run this command: _sudo dnf install pandoc ghostwriter_.
|
||||
|
||||
For those who are not aware of what [Markdown][5] is, here is a quick explanation. It is a simple markup language created a little over 15 years ago. It uses simple syntax to format plain text. Markdown files can then be converted to a whole slew of other document formats.
|
||||
|
||||
![ghostwriter][6]
|
||||
|
||||
Now for the tools. ghostwriter is a cross-platform Markdown editor that is easy to use and does not get in the way. pandoc is a very handy document converting tool that can handle hundreds of different formats.
|
||||
|
||||
To create your ebook, open ghostwriter, and start writing your document. If you have used Markdown before, you may be used to making the title of your document Heading 1 by putting a pound sign in front of it. Like this: _# My Man Jeeves_. However, pandoc will not recognize that as the title and put a big UNTITLED at the top of your ebook. Instead put a _%_ in front of your title. For example, _% My Man Jeeves_. Sections or chapters should be formatted as Heading 2, i.e. _## Leave It to Jeeves_. If you have subsections, use Heading 3 (_###_).
|
||||
|
||||
![][7]
|
||||
|
||||
Once your document is complete, click _File_ -> _Export_ (or press _Ctrl_ \+ _E_). In the dialog box, select between several options for the Markdown converter. If this is the first time you have used ghostwriter, the Sundown converter will be picked by default. From the dialog box, select pandoc. Next click _Export_. Your EPUB file is now created.
|
||||
|
||||
![ghostwriter export dialog box][8]
|
||||
|
||||
Note: If you get an error saying that there was an issue with pandoc, turn off _Smart Typography_ and try again.
|
||||
|
||||
### Method 2: calibre
|
||||
|
||||
If you want a more polished ebook, this is the method that you are looking for. It takes a few more steps, but it’s worth it.
|
||||
|
||||
![][9]
|
||||
|
||||
First, install an application named [calibre][10]. calibre is not just an ebook reader, it is an ebook management system. You can either install it from the Software Center or from the terminal via _sudo dnf install calibre_.
|
||||
|
||||
In this method, you can either write your document in LibreOffice, ghostwriter, or another editor of your choice. Make sure that the title of the book is formatted as Heading 1, chapters as Heading 2, and sub-sections as Heading 3.
|
||||
|
||||
Next, export your document as an HTML file.
|
||||
|
||||
Now add the file to calibre. Open calibre and click “_Add books_“. It will take calibre a couple of seconds to add the file.
|
||||
|
||||
![][11]
|
||||
|
||||
Once the file is imported, edit the file’s metadata by clicking on the “_Edit metadata_” button. Here you can fill out the title of the book and the author’s name. You can also upload a cover image (if you have one) or calibre will generate one for you.
|
||||
|
||||
![][12]
|
||||
|
||||
Next, click the “_Convert books_” button. In the new dialog box, select the “_Look & Feel_” section and the “_Layout_” tab. Check the “_Remove spacing between paragraphs_” option. This will tighten up the contents as indent each paragraph.
|
||||
|
||||
![][13]
|
||||
|
||||
Now, set up the table of contents. Select the “_Table of Contents_” section. There are three options to focus on: Level 1 TOC, Level 2 TOC, and Level 3 TOC. For each, click the wand at the end. In this new dialog box, select the HTML tag that applies to the table of contents entry. For example, select _h1_ for Level 1 TOC and so on.
|
||||
|
||||
![][14]
|
||||
|
||||
Next, tell calibre to include the table of contents. Select the “_EPUB output_” section and check the “_Insert Inline Table of Contents_“. To create the epub file, click “_OK_“.
|
||||
|
||||
![][15]
|
||||
|
||||
Now you have a professional-looking ebook file.

如何在 Fedora 上生成一个 EPUB 文件
|
||||
======
|
||||
|
||||
![][1]
|
||||
|
||||
在智能手机上阅读内容中正在变得越来越流行。每一部手机都有它自己的电子书阅读器。不管相信与否，在 Fedora 创建你自己的电子书文件是非常容易的。
|
||||
|
||||
这篇展示使用两种不同的方法来创建一个 [EPUB][2] 文件。Epub 格式是最流行的格式之一，并且被很多开源软件所支持。
|
||||
|
||||
绝大数的人们将会询问 “在很容易创建 PDF 文件的情况下，为什么要花费时间和精力来创建 EPUB 文件?” 答案是: “你曾经尝试看过每次只能看到一张纸的一小部分的吗?”为阅读一个 PDF 文件，你不得不保持缩放和移动文档，或者将其缩放到一个小尺寸来适合屏幕。在另一方面，EPUB 文件被设计成适合很多不同的屏幕类型。
|
||||
|
||||
### 方法 1: ghostwriter 和 pandoc
|
||||
|
||||
第一种方法创建一个速成版的电子书文件。它使用一个名为 [ghostwriter][3] 的 Markdown 编辑器，和一个名为 [pandoc][4]的命令行文档转换工具。
|
||||
|
||||
你可以从软件中心搜查和安装它们，也可以从从终端中安装它们。如果你将使用终端来安装它们，运行这个命令: _sudo dnf install pandoc ghostwriter_ 。
|
||||
|
||||
对于那些不知道 [Markdown][5] 是什么的人们来说，在这里有一个速成版解释。它是一个大约在15年前创建的简单的标记语言它使用简单的语法来格式化纯文本。Markdown 文件可以随后转换成很多其它文档格式的文件。
|
||||
|
||||
![ghostwriter][6]
|
||||
|
||||
现在，对于工具来说。ghostwriter 是一个跨平台的易于使用的 Markdown 编辑器。pandoc 是一个非常易于使用的文档转换工具，可以处理数百种不同的格式。
|
||||
|
||||
为了创建你的电子书，打开 ghostwriter ，并开始编写你的文档。如果你以前使用过 Markdown ，您可能习惯于在文档标题1的前面放置一个 # 符号来制作标题。像这样: _# My Man Jeeves_。然而，pandoc 将不会识别其为标题，并将在你的电子书的顶部放置一个一个大的 UNTITLED 。相反地在你的标题前放置一个 _%_ 来制作标题。例如， _% My Man Jeeves_ 。章节应该被格式为标题2，例如， _## Leave It to Jeeves_。如果你有子章节，使用标题3 (_###_) 。
|
||||
|
||||
![][7]
|
||||
|
||||
在你的文档完成后，单击 _文件_ -> _导出_ (或按 _Ctrl_ + _E_ 键)。在对话框中，在 Markdown 转换器中的几个选项中进行选择。如果这是你第一次使用 ghostwriter ，将默认选择 Sundown 转换器。从对话框中，选择 pandoc 。接下来单击 _导出_ 。现在你的 EPUB 文件已经创建好了。
|
||||
|
||||
![ghostwriter 导出对话框][8]
|
||||
|
||||
注意: 如果你获取一个说明 pandoc 有问题的错误，关闭 _智能排版_ ，并再试一次。
|
||||
|
||||
### 方法 2: calibre
|
||||
|
||||
如果你想要一个更完美的电子书，这就是你正在苦苦追寻的方法。它采用更多的步骤，但是它是值得的。
|
||||
|
||||
![][9]
|
||||
|
||||
首先，安装一个名为 [calibre][10] 的应用程序。calibre 不仅仅是一个电子书阅读器，它也是一个电子书管理器系统。你可以从软件中心安装它，也可以从终端安装它，通过 _sudo dnf install calibre_ ：
|
||||
|
||||
在这个方法中，你可以在 LibreOffice ，ghostwriter，或者其它你选择的编辑器中编写你的文档。确保书籍的标题被格式为标题1，章节被格式为标题2，子章节被格式为标题3。
|
||||
|
||||
接下来，导出你的文档为一个 HTML 文件。
|
||||
|
||||
现在添加该文件到 calibre 。打开 calibre ，并单击 “_添加书籍_“。它将花费 calibre 几秒钟来添加文件。
|
||||
|
||||
![][11]
|
||||
|
||||
在文件导入后，通过单击“_编辑元数据_” 按钮来编辑文件的元数据。在这里你可以填写书的标题和作者的姓名。你也可以上传一个封面图片(如果你有的话)，或者 calibre 将为你生成一个封面。
|
||||
|
||||
![][12]
|
||||
|
||||
接下来，单击“_转换书籍_”按钮。在新的对话框中，选择“_界面外观_” 部分和“_布局_” 标签页。勾选 “_删除段间空行_” 选项。这将更加严格地缩进每一段的内容。
|
||||
|
||||
![][13]
|
||||
|
||||
现在，设置目录。选择 “_内容目录_” 部分。这里有三个需要注意的选项: Level 1 TOC, Level 2 TOC,和 Level 3 TOC。对于每一个选项来说，在其尾处的魔法棒按钮上单击来选择。在新的对话框中，选择应用于目录表项的 HTML 标记。例如，为 Level 1 TOC 选择 _h1_ 。
|
||||
|
||||
![][14]
|
||||
|
||||
接下来，告诉 calibre 包含内容目录。选择“_EPUB 输出_” 部分并勾选 “_插入内联目录_“。为了创建 epub 文件，单击“_确定_“。
|
||||
|
||||
![][15]
|
||||
|
||||
现在，你有一个看起来很专业的电子书文件。
