This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

IceGlass is a macOS menu bar application that provides NHL game situational awareness. It shows recent scores, upcoming games, and game states for all NHL teams in a yesterday/today/tomorrow window. The app fetches live data from the NHL API and displays it in a dropdown menu.

Building and Testing

Build Commands

# Generate Xcode project (after modifying project.yml)
xcodegen generate

# Build the project
xcodebuild -scheme IceGlass -configuration Debug build

# Build for release
xcodebuild -scheme IceGlass -configuration Release build

# Clean build folder
xcodebuild -scheme IceGlass clean

Running the App

Open IceGlass.xcodeproj in Xcode and run the scheme, or build and run the resulting .app bundle from the build directory.

Debug vs Release Builds

• DEBUG builds include a "Developer" menu with "Force Refresh"

Architecture

Core Services Pattern

The app uses a singleton-based architecture following the same pattern as the Ovi app:

1. MainService (Services/MainService.swift) - Central coordinator that:

   • Manages a single polling timer for the scoreboard API
   • Dynamically adjusts polling intervals based on game state (7s live, 180s pre-game, 600s game day, 3600s idle)
   • Filters API response to yesterday/today/tomorrow window in Eastern Time

2. StatusItemManager (Managers/StatusItemManager.swift) - Manages the menu bar item:

   • Displays NHL shield icon (template image for dark/light mode)
   • Creates and manages the NSStatusItem

3. MenuManager (Managers/MenuManager.swift) - Builds and updates the dropdown menu:

   • Displays games grouped by date (YESTERDAY/TODAY/TOMORROW headers)
   • Game rows show: away/home teams, scores, game state/time
   • Click opens NHL GameCenter; option-click opens NHL Videocast
   • Menu updates safely (skips during mouse clicks to prevent crashes)

API Integration

Single endpoint: https://api-web.nhle.com/v1/scoreboard/now

• Returns games grouped by date with scores, covering a multi-day window
• Response includes team names, abbreviations, scores, game state, period info

ApiService (Services/ApiService.swift) - Generic URL+callback fetcher

Game States (from NHL API)

Defined in Models/GameState.swift:

• FUT (Future) - More than 30 minutes before game start
• PRE (Pre-game) - Less than 30 minutes before puck drop
• LIVE - Game in progress
• CRIT - Last 5 minutes of regulation, OT, or SO
• OVER - Soft final (game over, not yet confirmed)
• FINAL - Hard final (confirmed by arena scorers)
• OFF - Official (confirmed by NHL statisticians)

Polling Intervals

Defined in Services/PollingInterval.swift:

• idle: 3600s (1 hour) - No games today
• bootstrap: 42s - Initial app launch
• gameDay: 600s (10 minutes) - Games scheduled today but not starting soon
• preGame: 180s (3 minutes) - Game starting within 30 minutes
• liveGame: 7s - Any game currently live
• everyMinute: 60s - Intermissions, post-game

Notification System

NotificationManager (Managers/NotificationManager.swift) - Handles macOS notifications:

• Game start notifications: triggered when game state transitions from FUT/PRE to LIVE
• Goal scored notifications: triggered when a team's score increases, with scoring team's logo attached
• Team logo PNGs (80x80) bundled in TeamLogos/ directory for UNNotificationAttachment
• Deduplicates via Set tracking: game IDs for starts, "gameId-awayScore-homeScore" keys for goals
• First fetch suppressed (no notifications on app startup)
• AppDelegate handles notification clicks to open URLs in browser

Change Detection (in MainService):

• previousGameStates: [Int: GameSnapshot] tracks game state and scores between polls
• detectChanges(in:) compares current vs previous to fire notifications

Team Logos

Downloaded from NHL CDN via Scripts/download_team_logos.sh:

• Source: https://assets.nhle.com/logos/nhl/svg/{TEAM}_light.svg?season={SEASON}
• SVGs stored in Assets.xcassets/TeamLogo_{TEAM}.imageset/ for future UI use
• PNGs (80x80) stored in TeamLogos/ as bundle resources for notification attachments
• Update logos each season by running the script with the new season parameter

Settings & Persistence

AppSettings (Managers/AppSettings.swift) - UserDefaults-backed:

• Launch at login (via SMAppService)
• Selected team filter (nil = all teams)

Eastern Time Handling

NHL operates on Eastern Time. Date extensions handle timezone conversions:

• Date+easternTimeZone.swift - ET timezone constant
• Date+etCalendar.swift - Calendar configured for ET
• Date+formatDateET.swift - ET date formatters
• Date+gameWindow.swift - Yesterday/today/tomorrow date computation in ET

Important Implementation Notes

• All services use singleton pattern with private initializers
• All singleton classes use @unchecked Sendable for Swift 6 strict concurrency
• Menu updates are skipped during mouse clicks (isSafe() check) to prevent crashes
• Timer rescheduling includes tolerance checks to avoid unnecessary invalidation
• Weak self references used throughout to prevent retain cycles
• XcodeGen is used to generate the Xcode project from project.yml
• LSUIElement=true in Info.plist (no dock icon, menu bar only)

Dependencies

• IndieAbout (SPM) - About window UI (https://git.rzen.dev/rzen/indie-about.git)
