​
Configuring a Theme

Your selected theme preferences are stored in your settings file. Open your settings from the command palette with “oppla: Open Settings” (bound to Cmd-, on macOS and Ctrl-, on Linux). Oppla’s AI can maintain adaptive themes that automatically adjust based on ambient light, time of day, and your activity patterns: 
{
  "theme": {
    "mode": "ai_adaptive",
    "light": "Oppla Light",
    "dark": "Oppla Dark",
    "ai_optimization": {
      "auto_adjust": true,
      "eye_strain_reduction": true,
      "context_aware_highlighting": true
    }
  }
}

​
Theme Modes

  • "system": Follow system appearance
  • "dark": Always use dark theme
  • "light": Always use light theme
  • "ai_adaptive": Let Oppla’s AI optimize theme selection

​
Theme Overrides with AI Assistance

Oppla’s AI can suggest theme overrides based on your coding patterns. Use the experimental.theme_overrides setting to customize specific attributes: 
{
  "experimental.theme_overrides": {
    "editor.background": "#1a1a2e",
    "ai.suggestion.background": "#16213e",
    "ai.suggestion.border": "#F5A742",
    "syntax": {
      "comment": {
        "font_style": "italic",
        "foreground": "#6c757d"
      },
      "ai_generated": {
        "font_style": "bold",
        "foreground": "#F5A742"
      }
    }
  }
}

​
AI-Specific Theme Attributes

Oppla introduces special theme attributes for AI features:
  • ai.suggestion.background - Background for AI code suggestions
  • ai.suggestion.border - Border color for AI suggestions
  • ai.inline.hint - Inline AI hint styling
  • ai.completion.highlight - AI completion highlighting

​
Local Themes

Store custom themes locally by placing them in the ~/.config/oppla/themes directory. Oppla’s AI will analyze your custom themes and suggest improvements for better readability and reduced eye strain. For example, to create a theme called my-ai-theme, create my-ai-theme.json in that directory. Oppla will validate the theme and provide AI-powered suggestions for color improvements.
AI Theme Validation: When you add a local theme, Oppla’s AI automatically analyzes it for:
  • Contrast ratios for accessibility
  • Color harmony
  • Syntax highlighting effectiveness
  • Eye strain factors

​
