B.Themes Multi-Theme Generation - Conversation History¶
Date: December 23, 2025 Generated by: Amazon Q Developer
Summary¶
Successfully implemented multi-theme generation in B.Themes allowing users to generate 1-100 diverse VSCode themes packaged into a single extension. Key enhancements include Peelee color generation integration, enhanced UI with validation, comprehensive error handling, and environment-based logging.
Key Features Implemented¶
Multi-Theme Generation¶
- Frontend input for 1-100 themes with validation
- Peelee library integration for diverse base colors
- Single .vsix package containing all themes
- Enhanced theme generator service
UI/UX Improvements¶
- Theme count input with 1-100 validation
- 10-character theme name limit
- Improved button layout (280px width, separate lines)
- Better error handling and status display
VSCode Extension Packaging¶
- Multi-theme package.json generation
- Extension name sanitization for compatibility
- Template system for multiple themes
- Comprehensive vsce integration
Logging & Configuration¶
- LOG_LEVEL environment variable support
- .env file integration with python-dotenv
- Priority: .env > system env > config > default
- Structured logging with timestamps
Technical Implementation¶
Frontend (React/TypeScript)¶
// Theme count validation
const [themeCount, setThemeCount] = useState(1);
onChange={(e) => setThemeCount(Math.max(1, Math.min(100, parseInt(e.target.value) || 1)))}
// Theme name length limit
onChange={(e) => setThemeName(e.target.value.slice(0, 10))}
Backend (Python/FastAPI)¶
# Pydantic validation
@validator('count')
def validate_count(cls, v):
if v is not None and (v < 1 or v > 100):
raise ValueError('count must be between 1 and 100')
# Multi-theme generation
base_colors = self.peelee_service.generate_base_colors(base_color, count)
for i, current_base_color in enumerate(base_colors):
theme_name = f"{name}-{i+1}" if count > 1 else name
viiv.generate_random_theme(current_base_color, theme_name, output_dir)
Peelee Integration¶
from peelee import peelee as P
def generate_base_colors(self, base_color: str, count: int) -> List[str]:
base_colors = P.generate_base_colors(base_color, count)
return base_colors
