+ } + +=head1 VERSION + +version 3.15 + +=head1 DESCRIPTION + +Travel::Status::DE::EFA is an unofficial interface to EFA-based departure +monitors. + +It can serve as a departure monitor, request details about a specific +trip/journey, and look up public transport stops by name or geolocation. +The operating mode depends on its constructor arguments. + +=head1 METHODS + +=over + +=item my $status = Travel::Status::DE::EFA->new(I<%opt>) + +Requests data as specified by I<opts> and returns a new Travel::Status::DE::EFA +object. B<service> and exactly one of B<coord>, B<stopfinder>, B<stopseq> or +B<name> are mandatory. Dies if the wrong I<opts> were passed. + +Arguments: + +=over + +=item B<service> => I<name> + +EFA service. See C<< efa-m --list >> for known services. +If you found a service not listed there, please notify +E<lt>derf+efa@finalrewind.orgE<gt>. + +=item B<coord> => I<hashref> + +Look up stops in the vicinity of the given coordinates. I<hashref> must +contain a B<lon> and a B<lat> element providing WGS84 longitude/latitude. + +=item B<stopfinder> => { B<name> => I<name> } + +Look up stops matching I<name>. + +=item B<stopseq> => I<hashref> + +Look up trip details. I<hashref> must provide B<stateless> (line ID), +B<stop_id> (stop ID used as start for the reported route), B<key> (line trip +number), and B<date> (departure date as YYYYMMDD string). + +=item B<name> => I<name> + +List departure for address / point of interest / stop I<name>. + +=item B<place> => I<place> + +Name of the place/city + +=item B<type> => B<address>|B<poi>|B<stop>|B<stopID> + +Type of the following I<name>. B<poi> means "point of interest". Defaults to +B<stop> (stop/station name). + +=item B<datetime> => I<DateTime object> + +Request departures for the date/time specified by I<DateTime object>. +Default: now. + +=item B<efa_encoding> => I<encoding> + +Some EFA servers do not correctly specify their response encoding. If you +observe encoding issues, you can manually specify it here. Example: +iso-8859-15. + +=item B<full_routes> => B<0>|B<1> + +If true: Request full routes for all departures from the backend. This +enables the B<route_pre>, B<route_post> and B<route_interesting> accessors in +Travel::Status::DE::EFA::Departure(3pm). + +=item B<proximity_search> => B<0>|B<1> + +If true: Show departures for stops in the proximity of the requested place +as well. + +=item B<timeout> => I<seconds> + +Request timeout, the argument is passed on to LWP::UserAgent(3pm). +Default: 10 seconds. Set to 0 or a negative value to disable it. + +=back + +=item my $status_p = Travel::Status::DE::EFA->new_p(I<%opt>) + +Returns a promise that resolves into a Travel::Status::DE::EFA instance +($status) on success and rejects with an error message on failure. In case +the error occured after construction of the Travel::Status::DE::EFA object +(e.g. due to an ambiguous name/place parameter), the second argument of the +rejected promise holds a Travel::Status::DE::EFA instance that can be used +to query place/name candidates (see name_candidates and place_candidates). + +In addition to the arguments of B<new>, the following mandatory arguments must +be set. + +=over + +=item B<promise> => I<promises module> + +Promises implementation to use for internal promises as well as B<new_p> return +value. Recommended: Mojo::Promise(3pm). + +=item B<user_agent> => I<user agent> + +User agent instance to use for asynchronous requests. The object must implement +a B<post_p> function. Recommended: Mojo::UserAgent(3pm). + +=back + +=item $status->errstr + +In case of an HTTP request or EFA error, returns a string describing it. If +none occured, returns undef. + +=item $status->lines + +Returns a list of Travel::Status::DE::EFA::Line(3pm) objects, each one +describing one line servicing the selected station. + +=item $status->name_candidates + +Returns a list of B<name> candidates if I<name> is ambiguous. Returns +nothing (undef / empty list) otherwise. + +=item $status->place_candidates + +Returns a list of B<place> candidates if I<place> is ambiguous. Returns +nothing (undef / empty list) otherwise. + +=item $status->stop + +Returns a Travel::Status::DE::EFA::Stop(3pm) instance describing the requested +stop. + +=item $status->stops + +In case the requested place/name is served by multiple stops and the backend +provides a list of those: returns a list of Travel::Status::DE::EFA::Stop(3pm) +instances describing each of them. Returns an empty list otherwise. + +=item $status->results + +In departure monitor mode: returns a list of +Travel::Status::DE::EFA::Departure(3pm) objects, each one describing one +departure. + +In coord or stopfinder mode: returns a list of +Travel::Status::DE::EFA::Stop(3pm) objects. + +=item $status->result + +In stopseq mode: Returns a Travel::Status::DE::EFA::Trip(3pm) object. + +=item Travel::Status::DE::EFA::get_service_ids() + +Returns the list of supported services (backends). + +=item Travel::Status::DE::EFA::get_service(I<service>) + +Returns a hashref describing the requested I<service> ID with the following keys. + +=over + +=item B<name> => I<string> + +Provider name, e.g. Verkehrsverbund Oberelbe. + +=item B<url> => I<string> + +Backend base URL. + +=item B<homepage> => I<string> (optional) + +Provider homepage. + +=item B<languages> => I<arrayref> (optional) + +Supportde languages, e.g. de, en. + +=item B<coverage> => I<hashref> + +Area in which the service provides near-optimal coverage.
