Mermaid安装及绘制流程图

Mermaid 插件的安装

卸载 Hexo 默认的渲染器

默认的 Hexo 安装包括一个 MarkDown 渲染器插件，该插件使用 

hexo-renderer-marked

，而 

hexo-renderer-markdown-it

是一款用于 Markdown 解析和渲染的插件，用于替换 Hexo 默认自带的 Markdown 渲染器，提供了更丰富的 Markdown 解析和渲染，替换命令如下：

npm un hexo-renderer-marked --save

npm i hexo-renderer-markdown-it --save

添加 Mermaid 支持

Mermaid 是一个支持 MarkDown 的流行的 

js

图标库。具有直接在Markdown中画流程图，甘特图，序列图等功能。

  • 使用 hexo-filter-mermaid-diagrams 的 Hexo 插件来实现相应的功能，在 Hexo 根目录执行如下命令安装：
npminstall hexo-filter-mermaid-diagrams --save
  • 修改在 Matery 主题目录 layout/_partial/ 下的 footer.ejs 文件，文末添加如下内容：
<%if(theme.mermaid.enable){%><script src='https://unpkg.com/mermaid@<%= theme.mermaid.version %>/dist/mermaid.min.js'></script><script>if(window.mermaid){
      mermaid.initialize({theme:'forest'});}</script><%}%>
  • 在 Hexo 根目录文件下 _config.yml 配置文件添加如下内容：
# mermaid chart。 依赖hexo-tag-mermaidmermaid:## mermaid url https://github.com/knsv/mermaidenable:true  # default falseversion: "latest" # default v7.1.2options:# find more api options from https://github.com/knsv/mermaid/blob/master/src/mermaidAPI.js#startOnload: true  // default true

执行 

hexo clean && hexo g

重新生成博客文件，在博文中使用含有 

mermaid

标签的代码块包裹 mermaid 正文内容 。

Mermaid 的配置

hexo-renderer-markdown-it

的所有配置，均在 Hexo 的根目录下配置文件

_config.yml

中进行配置。

简单配置

hexo-renderer-markdown-it

提供三种简单配置方式（配置级别）zero 、default 、commonmark 。

在 Hexo 的_config.yml 文件中可以配置以下内容：

# Markdown-it config# markdown: 'zero'# markdown: 'default'# markdown: 'commonmark'

每种简单配置其默认的一些设置：

  • zero ：禁用大多数解析器功能。仅支持斜体和粗体，甚至不支持所有原始 MarkDown 功能。
  • default（GFM）：解析器的行为类似于 GitHub 规范。
  • commonmark ：提供比 zero 预设更多的功能， 此设置将强制插件使用最新的 CommonMark 规范。

警告 ：选择一种简单配置，将阻止您使用任何附带的插件。

高级配置

hexo-renderer-markdown-it

提供的高级配置，是对简单配置的详细定制。在 Hexo 的根目录下 

_config.yml

文件中配置以下内容（官方提供的完整配置，没有特殊需要不用再次修改）。

# Markdown-it configmarkdown:render:html:truexhtmlOut:falsebreaks:truelinkify:truetypographer:truequotes:'“”‘’'plugins:- markdown-it-abbr

# Markdown-it configmarkdown:render:html:truexhtmlOut:falsebreaks:truelinkify:truetypographer:truequotes:'“”‘’'

html ：定义文档中的 HTML 内容是否应转义或传递给最终结果。

html:true # 不转义 HTML 内容html:false # 转义 HTML 内容，使标签作为文本输出

xhtmlOut ：定义解析器是否将导出完全兼容 XHTML 的标记。

xhtmlOut:true # 必须使用完全的 XHTML 代码，换行必须为 xhtmlOut:false # 不必必使用完全的 XHTML 代码，换行可以为

breaks ：使源文件中的换行符被解析为标记，每次按 Enter 键都会创建换行符。

breaks:true # 每次会车换行相当于一个标签breaks:false # Pa,每次会车换行会被忽略

linkify ：解析器能够将直接粘贴到文本中的链接内联。

linkify: true # 类似链接的文本，作为链接输出
linkify: false # 类似链接的文本，依然作为文本输出

typographer：可以替换常见的排版元素。

typographer: true # 替换常见的排版元素
typographer: false # 不替换常见的排版元素

quotes ：定义单引号、双引号如何被替换。

quotes: '“”‘’' # 'single'、"double" 变成 ‘single’、“double”
quotes: '«»“”' # 'single'、"double" 变成 “single”、«single»

绘制流程图

简介

所有流程图都由 

节点

、

几何形状

和 

边

、

箭头

/ 

线

组成。mermaid 定义了这些节点和边的制作和交互方式，还支持不同类型的箭头、多方向箭头以及与子图的连接。

节点

  • 默认节点。

默认节点展示在方格中，作为节点对象，也作为节点的名字。
