Gitbook book.json

---

1. 简介

配置 GitBook 允许您使用灵活的配置自定义您的书。这些选项在book.json文件中指定。

2. 通用配置

配置名	描述
root	包含所有图书文件的根文件夹的路径，除了book.json
structure	要指定自述文件、摘要、词汇表等的路径。请参阅结构段落。
title	您的书名，默认值是从 README 中提取的。在 legacy.gitbook.com 上，此字段已预先填写。
author	作者姓名。在 legacy.gitbook.com 上，此字段已预先填写。
isbn	书的 ISBN
language	书籍语言的ISO 代码，默认值为en
direction	文本的方向。可以是rtl或ltr，默认值取决于language
gitbook	应该使用的 GitBook 版本。使用SemVer规范并接受如下条件">= 3.0.0"

3. 插件配置

配置名	描述
plugins	要加载的插件列表
pluginsConfig	插件的配置

4. 结构配置

除了root变量之外，您还可以告诉 Gitbook 自述文件、摘要、词汇表、语言的文件名称（而不是使用默认名称，例如README.md）。这些文件必须位于您书籍的根目录（或每本语言书籍的根目录）。dir/MY_README.md不接受诸如此类的路径。

配置名	描述
structure.readme	自述文件名（默认为README.md）
structure.summary	摘要文件名（默认为SUMMARY.md）
structure.glossary	词汇表文件名（默认为GLOSSARY.md）
structure.languages	语言文件名（默认为LANGS.md）

5. PDF配置

PDF 输出可以使用以下中的一组选项进行自定义book.json：

多变的	描述
pdf.pageNumbers	在每页底部添加页码（默认为true）
pdf.fontSize	基本字体大小（默认为12）
pdf.fontFamily	基本字体系列（默认为Arial）
pdf.paperSize	纸张大小，选项为’a0’, ‘a1’, ‘a2’, ‘a3’, ‘a4’, ‘a5’, ‘a6’, ‘b0’, ‘b1’, ‘b2’, ‘b3’, ‘b4’, ‘b5’, ‘b6’, ‘legal’, ‘letter’（默认为a4）
pdf.margin.top	上边距（默认为56）
pdf.margin.bottom	下边距（默认为56）
pdf.margin.right	右边距（默认为62）
pdf.margin.left	左边距（默认为62）

6. 简单示例

gitbook 在编译书籍的时候会读取书籍源码顶层目录中的 book.js或者 book.json，这里以 book.json 为例.

{
    // Folders to use for output
    // Caution: it overrides the value from the command line
    // It's not advised this option in the book.json
    "output": null,

    // Generator to use for building
    // Caution: it overrides the value from the command line
    // It's not advised this option in the book.json
    "generator": "site",

    // Book metadats (somes are extracted from the README by default)
    "title": null,
    "description": null,
    "isbn": null,

    // For ebook format, the extension to use for generation (default is detected from output extension)
    // "epub", "pdf", "mobi"
    // Caution: it overrides the value from the command line
    // It's not advised this option in the book.json
    "extension": null,

    // Plugins list, can contain "-name" for removing default plugins
    "plugins": [],

    // Global configuration for plugins
    "pluginsConfig": {
        "fontSettings": {
            "theme": "sepia", "night" or "white",
            "family": "serif" or "sans",
            "size": 1 to 4
        }
    },

    // Variables for templating
    "variables": {},

    // Links in template (null: default, false: remove, string: new value)
    "links": {
        // Custom links at top of sidebar
        "sidebar": {
            "Custom link name": "https://customlink.com"
        },

        // Sharing links
        "sharing": {
            "google": null,
            "facebook": null,
            "twitter": null,
            "weibo": null,
            "all": null
        }
    },

    // Options for PDF generation
    "pdf": {
        // Add page numbers to the bottom of every page
        "pageNumbers": false,

        // Font size for the fiel content
        "fontSize": 12,

        // Paper size for the pdf
        // Choices are [u’a0’, u’a1’, u’a2’, u’a3’, u’a4’, u’a5’, u’a6’, u’b0’, u’b1’, u’b2’, u’b3’, u’b4’, u’b5’, u’b6’, u’legal’, u’letter’]
        "paperSize": "a4",

        // Margin (in pts)
        // Note: 72 pts equals 1 inch
        "margin": {
            "right": 62,
            "left": 62,
            "top": 36,
            "bottom": 36
        },

        //Header HTML template. Available variables: _PAGENUM_, _TITLE_, _AUTHOR_ and _SECTION_.
        "headerTemplate": null,

        //Footer HTML template. Available variables: _PAGENUM_, _TITLE_, _AUTHOR_ and _SECTION_.
        "footerTemplate": null
    }
}

首先，将book.json放到书籍代码顶层目录中，然后编译书籍：

$ gitbook build

可以看到，编译完成，使用

$ gitbook serve

然后将浏览器指向 http://127.0.0.1:4000，可以看到，什么都没有改变！

是的，虽然这里 book.json 文件非法，但是 gitbook build 并没有报错！

<aside>
💡 ConfigurationError: Error with book's configuration: config.isbn is not of a type(s) string

</aside>

所以，用户需要自己准备工具来保证 book.json 必须是一个合法的 JSON 文件，并且不能含有非法配置项。

首先，删除注释项，以及空行，如果是在 vim 中，可以执行下面的命令：

:%g/\s*\/\//d
:%g/^\s*$/d

然后，使用 python 来检查 book.json 是否合法，同样，在 vim 中执行下面的命令：

:%!python -m json.tool

很显然，下面的配置不能通过，所以删去（注：但是默认主题却是使用的这个配置！）。

    "pluginsConfig": {
        "fontSettings": {
            "theme": "sepia", "night" or "white",
            "family": "serif" or "sans",
            "size": 1 to 4
        }
    },

最后，剩下的内容如下：

{
    "description": null,
    "extension": null,
    "generator": "site",
    "isbn": null,
    "links": {
        "sharing": {
            "all": null,
            "facebook": null,
            "google": null,
            "twitter": null,
            "weibo": null
        },
        "sidebar": {}
    },
    "output": null,
    "pdf": {
        "fontSize": 12,
        "footerTemplate": null,
        "headerTemplate": null,
        "margin": {
            "bottom": 36,
            "left": 62,
            "right": 62,
            "top": 36
        },
        "pageNumbers": false,
        "paperSize": "a4"
    },
    "plugins": [],
    "title": null,
    "variables": {}
}

现在，修改一些配置，修改后为：

$ cat book.json 
{
    "author": "zongxun <me@ghostwritten>",
    "description": "This is a sample book created by gitbook",
    "extension": null,
    "generator": "site",
    "links": {
        "sharing": {
            "all": null,
            "facebook": null,
            "google": null,
            "twitter": null,
            "weibo": null
        },
        "sidebar": {
            "zongxun's Blog": "https://smoothies.com.cn"
        }
    },
    "output": null,
    "pdf": {
        "fontSize": 12,
        "footerTemplate": null,
        "headerTemplate": null,
        "margin": {
            "bottom": 36,
            "left": 62,
            "right": 62,
            "top": 36
        },
        "pageNumbers": false,
        "paperSize": "a4"
    },
    "plugins": [],
    "title": "Git Handbook",
    "variables": {}
}
