i3-weather

Simple Python script for grabbing weather information from OpenWeatherMap and (optionally) displaying it on your i3 status line.

Installation

Python 3 is required (I tested this code on Python 3.6). You can install in a virtualenv or else install the dependencies through your distribution's package manager.

$ python3 -m venv .env
$ .env/bin/pip install -r requirements.txt

OpenWeatherMap

i3-weather retrieves weather information from OpenWeatherMap. In order to use it, you'll need to register a (free) account and (free) API key.

Usage

With i3status

In your i3 configuration, update the bar's status_command to pipe through i3-weather:

bar {
    status_command i3status | /path/to/i3-weather/.env/bin/python /path/to/i3-weather/weather.py --wrap-i3-status --api-key ...
}

Standalone

i3-weather can also be invoked without using i3status to print the weather report in plain text. This is mostly useful for testing your command line arguments without having to restart i3 every time, but you could also use it to check the weather from your terminal.

$ cd /path/to/i3-weather
$ .env/bin/python weather.py --api-key ...

Specifying location

OpenWeatherMap's API supports 3 different ways of providing a location, which are supported by i3-weather as command-line arguments:

• --zip: look up a city by zip/postal code
  • For countries outside the US, you must also specify --zip-country
• --city-id: look up a city by OpenWeatherMap's "City ID". You can find this number in the URL when searching for your location on OpenWeatherMap's website (for example, Seattle is https://openweathermap.org/city/5809844, which corresponds to --city-id 5809844).
• --place: look up a location by place name (typically city,country), e.g. Seattle,US

See the API documentation for more information about locations.

Customizing output format

i3-weather retrieves weather information from OpenWeatherMap for the provided location and formats the result from a user-provided format string (given with --format). The default format is {city}, {country}: {text}, {temp_f}°F, which produces an output similar to Seattle, US: light rain, 43°F.

The following format specifiers are supported:

• {city} - city name associated with the input location
• {country} - country name associated with the input location
• {wind_direction} - direction (in degrees) of the wind
• {wind_direction_fuzzy} - fuzzy direction of the wind (N, NE, etc.)
• {wind_direction_arrow} - arrow direction of the wind (↓, ↙, etc.)
• {wind_speed_mph} - speed of the wind in miles per hour
• {wind_speed_ms} - speed of the wind in meters per second
• {humidity} - relative humidity
• {pressure} - atmospheric pressure in hectopascals (millibars)
• {sunrise} - sunrise time (in current time zone)
• {sunset} - sunset time (in current time zone)
• {text} - basic description of condition (e.g "Fair" or "Partly cloudy")
• {temp_f} - temperature in Fahrenheit
• {temp_c} - temperature in Celsius
• {temp_k} - temperature in Kelvin
