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
