  • 用法
{% diff method="diffJson" %}

```json
{
"name": "gitbook-plugin-simple-mind-map",
"version": "0.2.1",
"description": "A gitBook plugin for generating and exporting mind map within markdown"
}

  • 预览
{
- "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 gitbookbook.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 methodoptions 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

  • ignoreCasetrue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

  • ignoreWhitespacetrue忽略前导和尾随空白。这与diffTrimmedLines相同
  • newlineIsTokentrue 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
  1. 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.
