DarkSky.py

DarkSky.py is a Python interface to the DarkSky REST api.

Requirements

• Python 2.7

Installation

From the root of the repo:

easy_install ./

That will pull in all the dependencies.

Usage

Using the DarkSky interface

Instantiate the DarkSky interface:

import darksky

ds_interface = darksky.DarkSky("api_key_goes_here")

The following methods are implemented on the interface object:

• getWeather; for getting the weather on a particular location (returns a DarkSkyResponse object)

current_weather = ds_interface.getWeather(
    latitude=1234.00,
    longitude=1235.11
)

• getInteresting; get a list of interesting storms
• getWeather; get weather for multiple points. With optional time elements.

import datetime

conditions = ds_interface.getWeathers(
    points=[
        {
            "latitude":1234.0,
            "longitude":1234.11,
            "time":datetime.datetime(
                year=2012,
                month=6,
                day=4
            )
        },
        {
            "latitude":1235.0,
            "longitude":1235.11,
            "time":datetime.datetime(
                year=2012,
                month=6,
                day=3
            )
        },
    ]
)

Using the DarkSkyResponse object

The DarkSkyResponse object has all the response properties set as object properties:

>>> ds_response.currentTemp
75
>>> ds_response.currentSummary
'light rain'
>>> ds_response.hourSummary
'light rain for 13 minutes'
>>> ds_response.isPrecipitating
True
>>> cw.dayPrecipitation[0]
{'type': 'rain', 'temp': 74, 'probability': 0.5586104718059857, 'time': datetime.datetime(2012, 5, 28, 14, 0)}

Note that dates are native Python date objects. This also allows the special methods:

• getTimeToChange; return the time the change is predicted to occur
• getTimeToTimeout; return the time to the timeout

The hourSummary property is dynamic. It will always be represented as the time from now until the event is to take place. If you attempt to access it after the event has taken place, it will read "event for 0 minutes".

For example:

>>> cw.hourSummary
'light rain for 13 minutes'

Two minutes later:

>>> cw.hourSummary
'light rain for 11 minutes'

Running the tests

1. Install the requirements (not included in setup.py)

   pip install -r requirements.txt

2. From the src directory, execute the tests

   nosetests ../tests/*
