118 This module wraps L<http://www.oxontime.com> to provide live bus
119 departures in Oxford.
121 Two methods can be exported (none by default):
125 =item B<stops_for_route>(I<$route_id>)
127 Given a route ID (these can be obtained by inspecting the homepage of
128 Oxontime), returns in list context a list of hashrefs having the keys
129 C<stopName> (name of stop) and C<stopId> (ID of stop, suitable for
130 passing to C<departures_for_stop>). In scalar context, an arrayref
131 containing this list is returned.
133 =item B<departures_for_stop>(I<$stop_id>)
135 Given a stop ID (these can be obtained by inspecting the homepage of
136 Oxontime or by calling C<stops_for_route>), returns in list context a
137 list of hashrefs having the keys C<service> (name of service and
138 company that runs it), C<destination> (where the service is finishing)
139 and C<departs> (L<Time::Piece> object representing the time when the
140 service departs). In scalar context, an arrayref containing the list
143 Note that C<departs> is in the time zone of Oxford, but Time::Piece
144 interprets it as being in local time. If local time is different from
145 time in Oxford, this needs to be taken into account.
147 =item B<nextbus_from_to>(I<$from>, I<$to>)
149 Given a place to start from and a place to arrive at this method
150 returns a list of the next buses to serve that route. I<$from> must be
151 one of the 8 provided constants:
153 NEXTBUS_FROM_HEADINGTON_CAMPUS
154 NEXTBUS_FROM_HARCOURT_HILL
155 NEXTBUS_FROM_MARSTON_ROAD
156 NEXTBUS_FROM_WHEATLEY_CAMPUS
157 NEXTBUS_FROM_CRESCENT_HALL
158 NEXTBUS_FROM_PAUL_KENT_HALL
159 NEXTBUS_FROM_SLADE_PARK
160 NEXTBUS_FROM_CITY_CENTRE
162 whereas I<$to> is the name of an important station.
164 This function calls the Nextbus service at
165 L<http://nextbus.brookes.ac.uk/>. It is unclear what values for I<$to>
166 are implemented by Nextbus; it is probably best to inspect the website
167 to see what destinations are available.
