## Overview
|
|
|
|
The theme provides Kotlin code demonstrations, supporting online execution of Kotlin code.
|
|
|
|
::: important
|
|
This feature works by submitting code to a server for compilation and execution, and only a single code file can be submitted at a time.
|
|
|
|
Therefore, please do not use this feature to execute overly complex code, and avoid making execution requests too frequently.
|
|
:::
|
|
|
|
## Configuration
|
|
|
|
This feature is disabled by default. You can enable it through configuration.
|
|
|
|
```ts title=".vuepress/config.ts"
|
|
export default defineUserConfig({
|
|
theme: plumeTheme({
|
|
markdown: {
|
|
repl: {
|
|
kotlin: true,
|
|
},
|
|
},
|
|
})
|
|
})
|
|
```
|
|
|
|
## Usage
|
|
|
|
Use the `::: kotlin-repl` container syntax to wrap Kotlin code blocks. The theme will inspect the code block and add an execution button.
|
|
|
|
### Read-Only Code Demo
|
|
|
|
Kotlin code demos are read-only by default and cannot be edited.
|
|
|
|
````md
|
|
::: kotlin-repl title="Custom Title"
|
|
```kotlin
|
|
// your kotlin code
|
|
```
|
|
:::
|
|
````
|
|
|
|
### Editable Code Demo
|
|
|
|
If you need online editing and execution, wrap the code block in the `::: kotlin-repl editable` container syntax.
|
|
|
|
````md
|
|
::: kotlin-repl editable title="Custom Title"
|
|
```kotlin
|
|
// your kotlin code
|
|
```
|
|
:::
|
|
````
|
|
|
|
