# Author: Matthew Raymer
# Description: Clean, modular Electron build script for TimeSafari application
# This script handles Electron builds with proper separation of concerns and
# no command chaining, following DRY principles.
#
# Usage:
#   ./scripts/build-electron.sh                    # Development build (runs app)
#   ./scripts/build-electron.sh --dev              # Development build (runs app)
#   ./scripts/build-electron.sh --test             # Test environment build
#   ./scripts/build-electron.sh --prod             # Production environment build
#   ./scripts/build-electron.sh --windows          # Windows build
#   ./scripts/build-electron.sh --mac              # macOS build
#   ./scripts/build-electron.sh --linux            # Linux build
#   ./scripts/build-electron.sh --appimage         # Linux AppImage
#   ./scripts/build-electron.sh --deb              # Debian package
#   ./scripts/build-electron.sh --dmg              # macOS DMG
#   ./scripts/build-electron.sh --help             # Show help
#   ./scripts/build-electron.sh --verbose          # Enable verbose logging
#
# Examples:
#   ./scripts/build-electron.sh --prod --windows   # Windows production build
#   ./scripts/build-electron.sh --test --appimage  # Linux AppImage test build
#   ./scripts/build-electron.sh --dev --mac        # macOS development build
#
# Exit Codes:
# 1 - Invalid arguments
# 2 - Electron cleanup failed
# 3 - Web build failed
# 4 - Capacitor sync failed
# 5 - TypeScript compilation failed
# 6 - Electron packaging failed
# 7 - Asset generation failed
# 8 - Electron app launch failed

TimeSafari Electron Build Script

Usage: $0 [OPTIONS]

Build Modes:
  --dev, --development    Development build (runs app)
  --test                  Test environment build
  --prod, --production    Production environment build
  --clean                 Clean Electron build artifacts only

Platforms:
  --windows               Windows build
  --mac                   macOS build
  --linux                 Linux build

Packages:
  --appimage              Linux AppImage
  --deb                   Debian package
  --dmg                   macOS DMG

Options:
  --verbose               Enable verbose logging
  --help                  Show this help message

Platform Validation:
  The script validates that the target platform matches the current
  execution platform. Cross-platform builds are not supported and
  will fail with an error message.

Examples:
  $0 --prod --windows     # Windows production build
  $0 --test --appimage    # Linux AppImage test build
  $0 --dev --mac          # macOS development build
  $0 --prod               # Production build for all platforms
  $0 --clean              # Clean Electron build artifacts only
