@mdit/plugin-include
在 Markdown 中包含其他文件的插件。
使用 仅限 Node.js 环境
import MarkdownIt from "markdown-it";
import { include } from "@mdit/plugin-include";
const mdIt = MarkdownIt().use(include, {
// 你的选项,currentPath 是必填的
currentPath: (env) => env.filePath,
});
mdIt.render("<!-- @include: ./path/to/include/file.md -->", {
filePath: "path/to/current/file.md",
});
const MarkdownIt = require("markdown-it");
const { include } = require("@mdit/plugin-include");
const mdIt = MarkdownIt().use(include, {
// 你的选项,currentPath 是必填的
currentPath: (env) => env.filePath,
});
mdIt.render("<!-- @include: ./path/to/include/file.md -->", {
filePath: "path/to/current/file.md",
});
由于 markdown-it 仅在 render()
api 中接收 markdown 内容,因此插件不知道当前内容的文件路径,因此不知道在哪里可以找到包含文件。
要解决这个问题,你应该通过 env 对象传递信息,并在插件选项中设置 currentPath
。
currentPath
函数将接收 env
对象并返回当前文件的路径。
此外,要支持别名,你可以在插件选项中设置 resolvePath
。
例如,以下代码添加了对 @src
别名的支持:
const MarkdownIt = require("markdown-it");
const { include } = require("@mdit/plugin-include");
const mdIt = MarkdownIt();
mdIt.use(include, {
currentPath: (env) => env.filePath,
resolvePath: (path, cwd) => {
if (path.startsWith("@src")) {
return path.replace("@src", "path/to/src/folder");
}
return path.join(cwd, path);
},
});
此外,默认情况下,包含文件中的图像和链接将相对于导入的文件进行解析,但是你可以通过在插件选项中将 resolveImagePath
和 resolveLinkPath
设置为 false
来更改此行为。
此外,该插件支持 deep
功能,如果此选项设置为 true
,它将处理包含文件中嵌套的 @include
。
格式
使用 <!-- @include: filename -->
导入文件。
如果要部分导入文件,你可以指定导入的行数
<!-- @include: filename{start-end} -->
<!-- @include: filename{start-} -->
<!-- @include: filename{-end} -->
同时你也可以导入文件区域:
<!-- @include: filename#region -->
文件区域
文件区域是 vscode 中的一个概念,区域内容被 #region
和 #endregion
注释包围。
这里有些例子:
<!doctype html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8" />
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Document</title>

嵌套与转义
你可以在选项中设置
deep: true
让插件递归处理导入 Markdown 文件的<!-- @include: -->
语法。你可以通过在
<-- @include -->
语法之前添加零宽空格 (U+200B
or​
) 来转义:​<!-- @include: ./demo.snippet.md -->
会被渲染为
选项
interface MarkdownItIncludeOptions {
/**
* 获得当前文件路径
*
* @default (path) => path
*/
currentPath: (env: any) => string;
/**
* 处理 include 文件路径
*
* @default (path) => path
*/
resolvePath?: (path: string, cwd: string | null) => string;
/**
* 是否深度导入包含的 Markdown 文件
*
* @default false
*/
deep?: boolean;
/**
* 是否使用 `<!-- @include: xxx -->` 代替 `@include: xxx` 导入文件
*
* @default true
*/
useComment?: boolean;
/**
