Travel::Status::DE::EFA - unofficial EFA departure monitor
=head1 SYNOPSIS
use Travel::Status::DE::EFA;
my $status = Travel::Status::DE::EFA->new(
efa_url => 'https://efa.vrr.de/vrr/XSLT_DM_REQUEST',
place => 'Essen', name => 'Helenenstr'
);
for my $d ($status->results) {
printf(
"%s %-8s %-5s %s\n",
$d->time, $d->platform_name, $d->line, $d->destination
);
}
=head1 VERSION
version 1.16
=head1 DESCRIPTION
Travel::Status::DE::EFA is an unofficial interface to EFA-based departure
monitors.
It reports all upcoming tram/bus/train departures at a given place.
=head1 METHODS
=over
=item my $status = Travel::Status::DE::EFA->new(I<%opt>)
Requests the departures as specified by I<opts> and returns a new
Travel::Status::DE::EFA object. B<efa_url>, B<place> and B<name> are
mandatory. Dies if the wrong I<opts> were passed.
Arguments:
=over
=item B<efa_url> => I<url>
URL to the EFA service. See C<< efa-m --list >> for known URLs.
If you found a URL not listed there, please notify
E<lt>derf+efa@finalrewind.orgE<gt>.
=item B<place> => I<place>
Name of the place/city
=item B<type> => B<address>|B<poi>|B<stop>
Type of the following I<name>. B<poi> means "point of interest". Defaults to
B<stop> (stop/station name).
=item B<name> => I<name>
address / poi / stop name to list departures for.
=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::Result(3pm).
=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 $status->errstr
In case of an HTTP request or EFA error, returns a string describing it. If
none occured, returns undef.
=item $status->identified_data
Returns a list of the identified values for I<place> and I<name>.
For instance, when requesting data for "E", "MartinSTR", B<identified_data>
will return ("Essen", "Martinstr.").
=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->results
Returns a list of Travel::Status::DE::EFA::Result(3pm) objects, each one describing
one departure.
=item Travel::Status::DE::EFA::get_efa_urls()
Returns a list of known EFA entry points. Each list element is a hashref with
the following elements.
=over
=item B<url>: service URL as passed to B<efa_url>
=item B<name>: Name of the entity operating this service
=item B<shortname>: Short name of the entity
=item B<encoding>: Server-side encoding override for B<efa_encoding> (optional)
=back
