Java Annotation Highlight

Customize colors for JVM-style annotations (@Override) and comments (//, /* */, <!-- -->) in Obsidian code blocks and notes.

This plugin does not collect telemetry, show ads, or make network requests. All highlighting runs locally.

Features

• Custom colors for @annotations (e.g. @Autowired, @Bean)
• Custom colors for // line comments and /* */ block comments
• Optional HTML comments: <!-- ... --> in note body and html/xml fences
• Works in Reading view and Editing (source / live preview)
• Configurable languages (default: java, kotlin, scala, groovy)
• Independent toggles for reading view vs editing view

Demo

```java
@Component
public class Demo {
    // line comment
    /* block comment */
    @Bean
    public String hello() {
        return "hi";
    }
}
```

<!-- section note -->
