Attrs support

Less than 1 minute

You can use custom syntax to add attrs for Markdown content.

Settings

import { hopeTheme } from "vuepress-theme-hope";

export default {
  theme: hopeTheme({
    plugins: {
      mdEnhance: {
        attrs: true,
      },
    },
  }),
};

Usage

You can use {attrs} to add attrs to Markdown content.

For example, if you want a heading2 "Hello World" with an id "say-hello-world", you can write:

## Hello World {#say-hello-world}

If you want an image with class "full-width", you can write:

![img](link/to/image.png) {.full-width}

Also, other attrs are supported, so:

A paragraph with some text. {#p .a .b align=center customize-attr="content with spaces"}

will be rendered into:

<p id="p" class="a b" align="center" customize-attr="content with spaces">
  A paragraph with some text.
</p>

Escaping

Escaping can be done by adding \ to escape the delimiter:

### Heading \{#heading}

will be

Heading {#heading}

Advanced

You can pass options to attrs to customize plugin behavior.

type MarkdownItAttrRuleName =
  | "fence"
  | "inline"
  | "table"
  | "list"
  | "hr"
  | "softbreak"
  | "block";

interface MarkdownItAttrsOptions {
  /**
   * left delimiter
   *
   * @default '{'
   */
  left?: string;

  /**
   * right delimiter
   *
   * @default '}'
   */
  right?: string;

  /**
   * allowed attributes
   *
   * @description An empty list means allowing all attribute
   *
   * @default []
   */
  allowed?: (string | RegExp)[];

  /**
   * Rules to enable
   *
   * @default "all"
   */
  rule?: "all" | boolean | MarkdownItAttrRuleName[];
}
