Stylize

Stylize inline tokens including changing tags, adding attributes and modifying content.

Settings

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

export default defineUserConfig({
  theme: hopeTheme({
    markdown: {
      stylize: [
        // options
      ],
    },
  }),
});

Usage

The stylize receives an array, where each element accepts 2 options:

• matcher: should be string or RegExp.

• replacer: a function customizing the matched token

For example, you can use the following config to transform *Recommended* into a Badge <Badge type="tip">Recommended</Badge>:

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

export default defineUserConfig({
  theme: hopeTheme({
    markdown: {
      stylize: [
        {
          matcher: "Recommended",
          replacer: ({ tag }) => {
            if (tag === "em")
              return {
                tag: "Badge",
                attrs: { type: "tip" },
                content: "Recommended",
              };
          },
        },
      ],
    },
  }),
});

Another example is you want to set all the emphasis n't words to red color, so that Setting this to a invalid syntax *doesn't* have any effect. becomes: "Setting this to an invalid syntax doesn't have any effect."

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

export default defineUserConfig({
  theme: hopeTheme({
    markdown: {
      stylize: [
        {
          matcher: /n't$/,
          replacer: ({ tag, attrs, content }) => {
            if (tag === "em")
              return {
                tag: "span",
                attrs: { ...attrs, style: "color: red" },
                content,
              };
          },
        },
      ],
    },
  }),
});

Also, you can use stylize in frontmatter to provide extra stylize rules for content of the page.

Performance

To avoid performance impact, you should try to avoid using RegExp for better performance unless you need it.

Also try to create snippets with RegExp having lower costs, e.g: RegExp starting with ^ and ending with $.

For example, if you only want to match "SHOULD", "MUST" and "MAY", you should write /^(?:SHOULD|M(?:UST|AY))$/u instead of /SHOULD|MUST|MAY/u. The fist one will only match 2 time with "A loo...oong content" with 1000 characters, but will match nearly 3000 times with the second RegExp.
