# AsciiDoc[](#asciidoc "Permalink")

GitLab 使用[Asciidoctor](https://asciidoctor.org) gem 将 AsciiDoc 内容转换为 HTML5\. 有关完整的 Asciidoctor 参考，请查阅《 [Asciidoctor 用户手册](https://asciidoctor.org/docs/user-manual/) 》.

## Syntax[](#syntax "Permalink")

这是最常用的 AsciiDoc 语法的简要参考. 您可以在[https://asciidoctor.org/docs/上](https://asciidoctor.org/docs/)找到有关 AsciiDoc 语法的完整文档.

### Paragraphs[](#paragraphs "Permalink")

```
A normal paragraph.
Line breaks are not preserved.
```

跳过以`//`开头的行注释：

```
// this is a comment
```

空白行分隔段落.

带有`[%hardbreaks]`选项的段落将保留换行符：

```
[%hardbreaks]
This paragraph carries the `hardbreaks` option.
Notice how line breaks are now preserved.
```

缩进（文字）段落会禁用文本格式，保留空格和换行符，并以等宽字体显示：

```
 This literal paragraph is indented with one space.
 As a consequence, *text formatting*, spaces,
 and lines breaks will be preserved.
```

一条警告段落引起了读者的注意：

```
NOTE: This is a brief reference, please read the full documentation at https://asciidoctor.org/docs/.

TIP: Lists can be indented. Leading whitespace is not significant.
```

### Text Formatting[](#text-formatting "Permalink")

**受约束的（应用于单词边界）**

```
*strong importance* (aka bold)
_stress emphasis_ (aka italic)
`monospaced` (aka typewriter text)
"`double`" and '`single`' typographic quotes
+passthrough text+ (substitutions disabled)
`+literal text+` (monospaced with substitutions disabled)
```

**不受限制（适用于任何地方）**

```
**C**reate+**R**ead+**U**pdate+**D**elete
fan__freakin__tastic
``mono``culture
```

**Replacements**

```
A long time ago in a galaxy far, far away...
(C) 1976 Arty Artisan
I believe I shall--no, actually I won't.
```

**Macros**

```
// where c=specialchars, q=quotes, a=attributes, r=replacements, m=macros, p=post_replacements, etc.
The European icon:flag[role=blue] is blue & contains pass:[************] arranged in a icon:circle-o[role=yellow].
The pass:c[->] operator is often referred to as the stabby lambda.
Since `pass:[++]` has strong priority in AsciiDoc, you can rewrite pass:c,a,r[C++ => C{pp}].
// activate stem support by adding `:stem:` to the document header
stem:[sqrt(4) = 2]
```

### Attributes[](#attributes "Permalink")

**用户定义的属性**

```
// define attributes in the document header
:name: value
```

```
:url-gem: https://rubygems.org/gems/asciidoctor

You can download and install Asciidoctor {asciidoctor-version} from {url-gem}.
C{pp} is not required, only Ruby.
Use a leading backslash to output a word enclosed in curly braces, like \{name}.
```

**环境属性**

GitLab 设置以下环境属性：

| Attribute | Description |
| --- | --- |
| `docname` | 源文档的根名称（无前导路径或文件扩展名）. |
| `outfilesuffix` | 对应于后端输出的文件扩展名（默认为`.adoc`以使文档间的交叉引用起作用）. |

### Links[](#links "Permalink")

```
https://example.org/page[A webpage]
link:../path/to/file.txt[A local file]
xref:document.adoc[A sibling document]
mailto:hello@example.org[Email to say hello!]
```

### Anchors[](#anchors "Permalink")

```
[[idname,reference text]]
// or written using normal block attributes as `[#idname,reftext=reference text]`
A paragraph (or any block) with an anchor (aka ID) and reftext.

See <<idname>> or <<idname,optional text of internal link>>.

xref:document.adoc#idname[Jumps to anchor in another document].

This paragraph has a footnote.footnote:[This is the text of the footnote.]
```
