        *One lib to route them all* - **routingpy** is a Python 3 client for several
        popular routing webservices.
        
        Inspired by `geopy <https://github.com/geopy/geopy>`_ and its great community of contributors, **routingpy** enables
        easy and consistent access to third-party spatial webservices to request **route directions**, **isochrones**
        or **time-distance matrices**.
        
        **routingpy** currently includes support for the following services:
        
        -  `Mapbox, either Valhalla or OSRM`_
        -  `Openrouteservice`_
        -  `Here Maps`_
        -  `Google Maps`_
        -  `Graphhopper`_
        -  `Local Valhalla`_
        -  `Local OSRM`_
        
        This list is hopefully growing with time and contributions by other developers. An up-to-date list is always available
        in our documentation_.
        
        **routing-py** is tested against CPython versions 3.7, 3.8, 3.9 and against PyPy3. As other major libraries like ``numpy``
        and ``pandas`` decided to drop Python 2 support, we did not see any reason to burden the project with the compatibility
        weight.

        Why routing-py?
        ---------------
        
        You want to
        
        - get from A to B by transit, foot, bike, car or hgv
        - compute a region of reachability
        - calculate a time distance matrix for a N x M table
        
        and don't know which provider to use? Great. Then **routingpy** is exactly what you're looking for.
        
        For the better or worse, every provider works on different spatial global datasets and uses a plethora of algorithms on top.
        While Google or HERE build on top of proprietary datasets, providers such as Mapbox or Graphhopper consume OpenStreetMap data
        for their base network. Also, all providers offer a different amount of options one can use to restrict the wayfinding.
        Ultimately this means that **results may differ** - and our experience tells us: they do, and not
        too little. This calls for a careful evaluation which service provider to use for which specific use case.
        
        With **routingpy** we have made an attempt to simplify this process for you.

        API
        -----------
        
        Every provider has its own specifications and features. However the basic blueprints are the same across all. We tried hard
        to make the transition from one provider to the other as seamless as possible. We follow two dogmas for all implementations:
        
        - All basic parameters have to be the same for all routers for each endpoint
        
        - All routers still retain their special parameters for their endpoints, which make them unique in the end
        
        This naturally means that usually those **basic parameters are not named the same way** as the endpoints they query. However,
        all **provider specific parameters are named the exact same** as their remote counterparts.
        
        The following table gives you an overview which basic arguments are abstracted:
        
        +-----------------------+-------------------+--------------------------------------------------------------+
        |       Endpoint        |     Argument      | Function                                                     |
        +=======================+===================+==============================================================+
        |   ``directions``      | locations         | | Specify the locations to be visited in order. Usually this |
        |                       |                   | | is done with ``[Lon, Lat]`` tuples, but some routers offer |
        |                       |                   | | additional options to create a location element.           |
        |                       +-------------------+--------------------------------------------------------------+
        |                       | profile           | | The mode of transport, i.e. car, bicycle, pedestrian. Each |
        |                       |                   | | router specifies their own profiles.                       |
        +-----------------------+-------------------+--------------------------------------------------------------+
        |   ``isochrones``      | locations         | | Specify the locations to calculate isochrones for. Usually |
        |                       |                   | | this is done with ``[Lon, Lat]`` tuples, but some routers  |
        |                       |                   | | offer additional options to create a location element.     |
        |                       +-------------------+--------------------------------------------------------------+
        |                       | profile           | | The mode of transport, i.e. car, bicycle, pedestrian. Each |
        |                       |                   | | router specifies their own profiles.                       |

        |                       | intervals         | | The ranges to calculate isochrones for. Either in seconds  |
        |                       |                   | | or in meters, depending on ``interval_type``.              |
        |                       +-------------------+--------------------------------------------------------------+
        |                       | intervals _type   | | The dimension of ``intervals``, which takes router         |
        |                       |                   | | dependent values, but generally describes time or distance |
        +-----------------------+-------------------+--------------------------------------------------------------+
        |      ``matrix``       | locations         | | Specify all locations you want to calculate a matrix       |
        |                       |                   | | for. If ``sources`` or ``destinations`` is not set, this   |
        |                       |                   | | will return a symmetrical matrix. Usually this is done     |

        Contributing
        ------------
        
        We :heart: contributions and realistically think that's the only way to support and maintain most
        routing engines in the long run. To get you started, we created a `Contribution guideline <./CONTRIBUTING.md>`_.
        
        Examples
        --------
        
        Follow our examples to understand how simple **routingpy** is to use.
        
        On top of the examples listed below, find interactive notebook(s) on mybinder.org_.
        
        Basic Usage
        ~~~~~~~~~~~
        
        Get all attributes
        ++++++++++++++++++
        
        **routingpy** is designed to take the burden off your shoulder to parse the JSON response of each provider, exposing
        the most important information of the response as attributes of the response object. The actual JSON is always accessible via
        the ``raw`` attribute:
        
        .. code:: python
        
            from routingpy import MapboxValhalla
            from pprint import pprint
        
            # Some locations in Berlin
            coords = [[13.413706, 52.490202], [13.421838, 52.514105],
                      [13.453649, 52.507987], [13.401947, 52.543373]]
            client = MapboxValhalla(api_key='mapbox_key')
        
            route = client.directions(locations=coords, profile='pedestrian')
            isochrones = client.isochrones(locations=coords[0], profile='pedestrian', intervals=[600, 1200])
            matrix = client.matrix(locations=coords, profile='pedestrian')
        
            pprint((route.geometry, route.duration, route.distance, route.raw))
            pprint((isochrones.raw, isochrones[0].geometry, isochrones[0].center, isochrones[0].interval))
            pprint((matrix.durations, matrix.distances, matrix.raw))
        
        
        Multi Provider
        ++++++++++++++
        
        Easily calculate routes, isochrones and matrices for multiple providers:
        
        .. code:: python
        
            from routingpy import Graphhopper, ORS, MapboxOSRM
            from shapely.geometry import Polygon
        
            # Define the clients and their profile parameter
            apis = (
               (ORS(api_key='ors_key'), 'cycling-regular'),
               (Graphhopper(api_key='gh_key'), 'bike'),
               (MapboxOSRM(api_key='mapbox_key'), 'cycling')
            )
            # Some locations in Berlin
            coords = [[13.413706, 52.490202], [13.421838, 52.514105],
                      [13.453649, 52.507987], [13.401947, 52.543373]]
        
            for api in apis:
                client, profile = api
                route = client.directions(locations=coords, profile=profile)
                print("Direction - {}:\n\tDuration: {}\n\tDistance: {}".format(client.__class__.__name__,
                                                                               route.duration,
                                                                               route.distance))
                isochrones = client.isochrones(locations=coords[0], profile=profile, intervals=[600, 1200])
                for iso in isochrones:
                    print("Isochrone {} secs - {}:\n\tArea: {} sqm".format(client.__class__.__name__,
                                                                           iso.interval,
                                                                           Polygon(iso.geometry).area))
                matrix = client.matrix(locations=coords, profile=profile)
                print("Matrix - {}:\n\tDurations: {}\n\tDistances: {}".format(client.__class__.__name__,
                                                                              matrix.durations,
                                                                              matrix.distances))
        
        
        Dry run - Debug
        +++++++++++++++
        
        Often it is crucial to examine the request before it is sent. Mostly useful for debugging:
        
        .. code:: python
        
            from routingpy import ORS
        
            client = ORS(api_key='ors_key')
            route = client.directions(
                locations = [[13.413706, 52.490202], [13.421838, 52.514105]],
                profile='driving-hgv',
                dry_run=True
            )
        
        
        Advanced Usage
        ~~~~~~~~~~~~~~
        
        Local instance of FOSS router
        +++++++++++++++++++++++++++++
        
        All FOSS routing engines can be run locally, such as openrouteservice, Valhalla, OSRM and GraphHopper. To be able
        to use **routingpy** with a local installation, just change the ``base_url`` of the client. This assumes that you did
        not change the URL(s) of the exposed endpoint(s):
        
        .. code:: python
        
            from routingpy import Valhalla
        
            # no trailing slash, api_key is not necessary
            client = Valhalla(base_url='http://localhost:8088/v1')
        
        Proxies, Rate limiters and API errors
        +++++++++++++++++++++++++++++++++++++
        
        Proxies are easily set up using following ``requests`` scheme for proxying. Also, when batch requesting, **routingpy**
        can be set up to resume its requests when the remote API rate limits (i.e. responds
        with HTTP 429). Also, it can be set up to ignore API errors and instead print them as warnings to ``stdout``. Be careful,
        when ignoring ``RouterApiErrors``, those often count towards your rate limit.
        
        All these parameters, and more, can optionally be **globally set** for all router modules or individually per instance:
        
        .. code:: python
        
            from routingpy import Graphhopper, ORS
            from routingpy.routers import options
        
            request_kwargs = dict(proxies=dict(https='129.125.12.0'))
        
            client = Graphhopper(
                api_key='gh_key',
                retry_over_query_limit=False,
                skip_api_error=True,
                requests_kwargs=request_kwargs
            )
        
            # Or alternvatively, set these options globally:
            options.default_proxies = {'https': '129.125.12.0'}
            options.default_retry_over_query_limit = False
            options.default_skip_api_error = True
