Introduction
Overview
The theme uses Shiki to implement syntax highlighting in Markdown code blocks.
Important Changes 1.0.0-rc.136
Starting from version 1.0.0-rc.136, the theme has migrated the code highlighting plugin from the internally implemented @vuepress-plume/plugin-shikiji to @vuepress/plugin-shiki provided by the vuepress ecosystem.
(No need to worry about significant changes - I am also one of the main developers of@vuepress/plugin-shiki, which implements functionality consistent with the theme's original plugin.)
Some configuration items require adjustments:
- The
languagesconfiguration has been changed to thelangsoption. You no longer need to manually add the languages you use; the plugin will automatically recognize and load language packages as needed. - The
themesconfiguration has been changed to:- When using a single theme configuration, use the
themeoption to configure the code block theme - When using dual theme configuration, use the
themesoption to configure the code block themes.
- When using a single theme configuration, use the
Languages
Shiki supports over 190+ languages. You can view the complete list of supported languages at languages.
You can use the following syntax to enable highlighting for code written in your chosen language:
``` [lang]
<!-- Your code content -->
```Where [lang] represents the programming language you are using.
Example:
``` js
const a = 1
console.log(a)
```const a = 1
console.log(a)Highlighting Themes
Shiki supports over 40+ highlighting themes.
You can find the complete list of supported themes at Themes and customize the highlighting theme according to your preference.
Theme Plume's default configuration for code block themes:
export default defineUserConfig({
theme: plumeTheme({
codeHighlighter: {
themes: { light: 'vitesse-light', dark: 'vitesse-dark' },
}
})
})The default configuration supports using the vitesse-light/vitesse-dark themes for light/dark modes respectively.
Additional Features
Thanks to the powerful capabilities of Shiki, Theme Plume provides additional feature support for code blocks, enhancing their expressive power.
Additionally, to facilitate better code demonstrations, Theme Plume provides syntax support for embedding CodePen, Js Fiddle, Code Sandbox, and Replit, allowing you to easily embed code demonstrations.
