{
-   "description": "A gitBook plugin for generating and exporting mind map within markdown",
-   "name": "gitbook-plugin-simple-mind-map",
+   "description": "A gitbook plugin for showing the differences between the codes within markdown",
+   "name": "gitbook-plugin-diff",
    "version": "0.2.1"
}

用法

步骤＃1-更新 book.json 文件

在您的 gitbook 的 book.json 文件中,将 diff 添加到 plugins 列表中.

这是最简单的示例:

{
    "plugins": ["diff"]
}

此外,受支持的配置选项如下:

"gitbook": {
    "properties": {
        "method": {
            "type": "string",
            "title": "jsdiff api method",
            "required": false,
            "default": "diffLines",
            "description": "some supported methods such as diffChars or diffWords or diffWordsWithSpace or diffLines or diffTrimmedLines or diffSentences or diffCss or diffJson or diffArrays"
        },
        "options": {
            "type": "object",
            "title": "jsdiff api options",
            "required": false,
            "description": "some methods may not support options"
        }
    }
}

步骤＃2- 使用 markdown 语法

diff 插件支持 method 和 options 等选项生成差异代码块.

这是在 markdown 文件中基本使用语法:

{% diff %}
```
old code
```
```
new code
```
{% enddiff %}

下面有一些基本示例:

Diff.diffChars(oldStr, newStr[, options])

区分两个文本块，逐个字符比较。

返回

返回更改对象列表（请参见下文）。

选项

• ignoreCase ：true忽略大小写差异。默认为false 。

示例

• 用法

设置method="diffChars"以调用Diff.diffChars(oldStr, newStr[, options])方法

{% diff method="diffChars" %}

```js
cat
```

```js
cap
```

{% enddiff %}

• 预览

  ca
- t
+ p

Diff.diffWords(oldStr, newStr[, options])

区分两个文本块，逐字比较，忽略空格。

返回

返回更改对象列表（请参见下文）。

选项

• ignoreCase ：与diffChars相同。

示例

• 用法

设置method="diffWords"来调用Diff.diffWords(oldStr, newStr[, options])方法

{% diff method="diffWords" %}

```bash
beep boop
```

```bash
beep boob blah
```

{% enddiff %}

• 预览

  beep
- boop
+ boob

+ blah

Diff.diffWordsWithSpace(oldStr, newStr[, options])

区分两个文本块，逐字比较，将空白视为有效。

返回

返回更改对象列表（请参见下文）。

选项

• ignoreCase ：与diffWords相同。

示例

• 用法

设置method="diffWordsWithSpace"以调用Diff.diffWordsWithSpace(oldStr, newStr[, options])方法

{% diff method="diffWordsWithSpace" %}

```bash
beep boop
```

```bash
beep boob blah
```

{% enddiff %}

• 预览

  beep
- boop
+ boob blah

Diff.diffLines(oldStr, newStr[, options])

比较两个文本块，逐行比较。

返回

返回更改对象列表（请参见下文）。

选项

• ignoreWhitespace ：true忽略前导和尾随空白。这与diffTrimmedLines相同
• newlineIsToken ：true newlineIsToken换行符视为单独的标记。这允许换行结构的更改独立于行内容而发生，并照此处理。通常，这是diffLines更加人性化的形式，并且diffLines更适合于补丁和其他计算机友好的输出。

示例

• 用法

设置method="diffLines"以调用Diff.diffLines(oldStr, newStr[, options])方法

{% diff method="diffLines",options={"newlineIsToken":true} %}

```bash
beep boop
the cat is palying with cap
what
```

```bash
beep boob blah
the cat is palying with cap
who
```

{% enddiff %}

• 预览

- beep boop

+ beep boob blah

  the cat is palying with cap

- what

+ who

Diff.diffTrimmedLines(oldStr, newStr[, options])

区分两个文本块，逐行比较，忽略前导和尾随空格。

返回

返回更改对象列表（请参见下文）。

选项

• ignoreWhitespace ：与diffLines相同。
• newlineIsToken ：同diffLines 。

示例

• 用法

设置method="diffTrimmedLines"来调用Diff.diffTrimmedLines(oldStr, newStr[, options])方法

{% diff method="diffTrimmedLines",options={"newlineIsToken":true} %}

```bash
beep boop
the cat is palying with cap
what
```

```bash
beep boob blah
the cat is palying with cat
who
```

{% enddiff %}

• 预览

- beep boop
  the cat is palying with cap
  what

+ beep boob blah
  the cat is palying with cat
  who

Diff.diffSentences(oldStr, newStr[, options])

区分两个文本块，逐句比较。

返回

返回更改对象列表（请参见下文）。

示例

• 用法

设置method="diffSentences"来调用Diff.diffSentences(oldStr, newStr[, options])方法

{% diff method="diffSentences" %}

```bash
beep boop
the cat is palying with cap
what
```

```bash
beep boob blah
the cat is palying with cat
who
```

{% enddiff %}

• 预览

- beep boop
  the cat is palying with cap
  what

+ beep boob blah
  the cat is palying with cat
  who

Diff.diffCss(oldStr, newStr[, options])

比较两个文本块，比较 CSS 标记。

返回

返回更改对象列表（请参见下文）。

示例

• 用法

设置method="diffCss"来调用Diff.diffCss(oldStr, newStr[, options])方法

{% diff method="diffCss" %}

```css
.markdown-section h1, .markdown-section h2, .markdown-section h3, .markdown-section h4, .markdown-section h5, .markdown-section h6 {
    margin-top: 1.275em;
    margin-bottom: .85em;
    font-weight: 700;
}
```

```css
.markdown-section h1, .markdown-section h2, .markdown-section h3, .markdown-section h4, .markdown-section h5, .markdown-section h6 {
    margin-top: 1.5em;
    margin-bottom: 1em;
}
```

{% enddiff %}

• 预览

  .markdown-section h1, .markdown-section h2, .markdown-section h3, .markdown-section h4, .markdown-section h5, .markdown-section h6 {
    margin-top:
- 1.275em
+ 1.5em
  ;
    margin-bottom:
- .85em
+ 1em
  ;
-
    font-weight: 700;

}

Diff.diffJson(oldObj, newObj[, options])

比较两个 JSON 对象，比较每个对象上定义的字段。在此比较中，字段的顺序等并不重要。

返回

返回更改对象列表（请参见下文）。

步骤＃3- 运行 gitbook 命令

1. 运行 gitbook install .它将自动为您的 gitbook 安装 diff 插件.

该步骤仅需要允许一次即可.

gitbook install

或者您可以运行 npm install gitbook-plugin-diff 命令本地安装 gitbook-plugin-diff 插件.

npm install gitbook-plugin-diff

2. 像往常一样构建您的书（ gitbook build ）或服务（ gitbook serve ）.

gitbook serve

示例

• 官方文档配置文件

https://github.com/snowdreams1006/gitbook-plugin-diff/blob/master/docs/book.json^[7]

{
    "plugins": ["diff"],
    "pluginsConfig": {
        "diff": {
            "method": "diffJson"
        }
    }
}

• 官方示例配置文件

https://github.com/snowdreams1006/gitbook-plugin-diff/blob/master/example/book.json^[8]

{
    "plugins": ["diff"],
    "pluginsConfig": {
        "diff": {
            "method": "diffJson"
        }
    }
}

• 示例book.json文件

{
    "plugins": ["diff"]
}

或者您可以将 method 设置为默认方法用于代码之间进行比较方式：

{
    "plugins": ["diff"],
    "pluginsConfig": {
        "diff": {
            "method": "diffChars"
        }
    }
}

或者您可以根据方法将 options 设置为默认选项.

{
    "plugins": ["diff"],
    "pluginsConfig": {
        "diff": {
            "method": "diffChars",
            "options": {
              "ignoreCase": true
            }
        }
    }
}

注意 ：如果您的书还没有创建,以上代码段可以用作完整的 book.json 文件.
