[ENHANCEMENT] Google Maps walking distance calculation

[fgnn]

By using the google map api to get directions from your location to the pokemons location, you can get an accurate walking distance and time. While at work, I can see at a glance whether I can walk to the pokemon in time or not without having to open the link.

The code in the fork works and I've been using it for a few days. Unfortunately I am a subversion guy and don't understand git at all. Something went very wrong with the commit and pull request... Hopefully someone can do a proper update of the code. Its now a few commits behind master since I waited a day. https://github.com/fgnn/PokeAlarm/commit/dbe284d0dd22d374eb8ecc154e0f1a75255e7f68

features:

• added google-maps api key to the config file.
• implemented different messages for slack only.
• unicode arrow indicating the compass direction from you to the pokemon (8 directions)
• time and distance walking to pokemon
• a "walking"emoji if you can walk there in time, otherwise a red "no" emoji.

Wow this is incredible, would love to see it integrated

@fgnn If you could provide me the snippet of the code you used, I will look into this.

Yeah this would be awesome! It looks like @fgnn cited his commits... maybe I'm blind but I don't see the changes there?

The DistanceMatrix Googlemaps API is what we should use. However, while in the docs they say an API key is a required paremeter, it seems that data is returned without one.

If an API key was needed though, it'd be a bit of a non-starter, as every poke alarm would result in an API call which would count against the quote.

It's as easy as querying here for a json and change the paremeters accordingly: https://maps.googleapis.com/maps/api/distancematrix/json?origins=43.041780,-87.909758&destinations=43.043215,-87.903911&mode=walking&units=imperial

There's actually a python package, googlemaps, that will query this. However, the constructor refuses to work without an API key being supplied.

import googlemaps
gmaps = googlemaps.Client(key="YOURKEYHERE")
dist = gmaps.distance_matrix((43.041780,-87.909758),(43.043215,-87.903911), 'walking')
print "%s" % dist.get("rows")[0].get("elements")[0].get("duration").get("text")

That's exactly how I implemented it.

I looked at my fork again and it looks like I messed up even more than I thought and the code didn't get uploaded at all.

Tonight I will take another stab at attempting to get it uploaded.

Finally figured out how to use git!

This should now be implimented as of commit fc60ddc7231c1ce515f2d343022eb33ebf80464d. You can add in the following options

<walk_time> or <walk_dist> <bike_time> or <bike_dist> <drive_time> or <drive_dist>
