Features

• Shows temperature with a weather emoji in the menu bar
• Dropdown with city name, conditions, humidity, and wind speed
• Auto-detects location via IP geolocation — no configuration required
• Supports manual coordinates for pinpoint accuracy
• Fahrenheit or Celsius
• No API key needed — uses the free Open-Meteo API
• No external dependencies beyond standard macOS tools (curl, bc)

Installation

1. Install SwiftBar (or xbar).
2. Copy weather.30m.sh to your SwiftBar plugins directory.
3. Make it executable:

   chmod +x weather.30m.sh

4. SwiftBar will pick it up automatically and refresh every 30 minutes.

Configuration

Open the plugin's variable editor in SwiftBar to set:

Variable	Default	Description
VAR_LATITUDE	(empty)	Latitude — leave blank to auto-detect via IP
VAR_LONGITUDE	(empty)	Longitude — leave blank to auto-detect via IP
VAR_UNIT	fahrenheit	fahrenheit or celsius

When coordinates are left blank, the plugin resolves your location from ipinfo.io and caches the result for 6 hours to avoid repeated lookups.

How It Works

1. Location — resolves via ipinfo.io/json (IP-based geolocation) or user-supplied coordinates. Results are cached at /tmp/swiftbar_weather_location.cache for 6 hours.
2. Weather data — fetches current conditions from api.open-meteo.com using the WMO weather code, temperature, humidity, and wind speed fields.
3. JSON parsing — done with sed only; no jq required.
4. Output — formats the menu bar line and dropdown according to the SwiftBar plugin protocol.

Dependencies

• curl — HTTP requests
• bc — floating-point math

Both ship with macOS.
