Copy Code
Overview
This feature is powered by @vuepress/plugin-copy-code.
The code copying feature is enabled by default in the theme. It supports one-click copying of code displayed in articles.
By default, the theme adds a copy button to every code block. This button is only displayed on desktop.
When hovering over a code block, a copy button appears in the top-right corner.
Configuration
Modify the behavior of code copying in the .vuepress/config.ts configuration file:
export default defineUserConfig({
theme: plumeTheme({
// copyCode: false // Disable code copying
copyCode: {
// ...More configurations
}
})
})showInMobile
- Type:
boolean - Default:
false
Whether to show the copy button on mobile devices.
ignoreSelector
- Type:
string | string[] - Default:
[]
CSS selector for elements within code blocks to be ignored during copying.
Example: ['.token.comment'] will ignore nodes with the class .token.comment in code blocks (this would ignore comments in prismjs).
inlineSelector
- Type:
string | string[] | boolean - Default:
false
Whether to copy inline code content on double-click.
boolean: Whether to copy inline code content on double-click.
string[] | string: Selector indicating which inline code content should be copyable.
transform Composition API Only
- Type:
(preElement: HTMLPreElement) => void - Default:
null
A transformer function to modify the code block content within <pre> before copying. This option is only effective when using useCopyCode().
Composition API
The Composition API for this feature can be configured in .vuepress/client.ts:
import { defineClientConfig } from '@vuepress/client'
import { useCopyCode } from '@vuepress/plugin-copy-code/client'
export default defineClientConfig({
setup() {
useCopyCode({
// ...
})
},
})Example
Add copyright information when copying code:
import { defineClientConfig } from '@vuepress/client'
import { useCopyCode } from '@vuepress/plugin-copy-code/client'
export default defineClientConfig({
setup() {
useCopyCode({
transform: (preElement) => {
// Insert copyright information
pre.innerHTML += `\n Copied by vuepress-theme-plume`
},
})
},
})Contributors
