version 6.14

hafas-m is an interface to HAFAS public transport services such as the one operated by Deutsche Bahn.

It can serve as an arrival/departure monitor, request details about a specific trip/journey, and look up public transport stops by name or geolocation. The operating mode depends on the contents of its non-option argument.

Show departures (or arrivals) at station, optionally filtered by mode of transport. station may be given as a station name or HAFAS station ID. For each train, hafas-m shows

* estimated departure (or arrival) time,

* delay, if known,

* trip name, number, or line,

* direction / destination,

* platform, if known (! indicates a platform change), and

* expected occupancy of first and second class, if known.

Times are always given in the selected service's default time zone (see --list). Times that differ from the queried stop's local time are marked with *. Occupancy indicators are, from least occupied to fully booked: . o * !.

List stations that match query or that are located in the vicinity of lat:lon geocoordinates with EVA ID and name.

Show trip details (see below) for the train number provided in query (e.g. "ICE 205" or "S 31111") if it resolves into a single journey ID. Otherwise, list all journey IDs that match query.

List intermediate stops of journeyID (as given by arrival/departure monitor mode when invoked with -j, --with-jid) with arrival/departure time, delay (if available), occupancy (if available), and stop name. Also includes line/journey, operator, and heading information.

Times are reported in the selected HAFAS service's default time zone (typically Europe/Berlin). If a stop's local time differs, it is also provided.

Values in brackets indicate options that only apply to the corresponding operating mode(s).

-a, --arrivals (monitor)

Show arrivals instead of departures, including trains ending at the specified station. Note that this causes the output to display the start instead of the end station.

-d, --date dd.mm.[yyyy]

Request date. Default: today.

-j, --with-jid (monitor)

Show journey IDs in arrival/departure board. These can be used to obtain details on individual journeys with subsequent hafas-m invocations.

--json

Print result(s) as JSON and exit. This is a dump of internal data structures and not guaranteed to remain stable between minor versions. Please use the Travel::Status::DE::HAFAS(3pm) module if you need a proper API.

-l, --language language

Request free-text messages to be provided in language. See --list for a list of languages supported by individual HAFAS instances. Note that requesting an invalid/unsupported language may lead to garbage output.

--list

List known HAFAS instances and exit. Use -s|--service to select a service from this list for a HAFAS request.

-m, --mot motlist (monitor)

By default, hafas-m shows all modes of transport arriving/departing at the specified station. With motlist, it is possible to either exclude a list of modes, or exclusively show only a select list of modes.

To exclude modes, set motlist to !mot1,!mot2,...

To show them exclusively, set motlist to mot1,mot2,...

The mot types depend on the used service. Use -m help to list them.

-n, --num-results count (monitor)

Request up to count results. Default: 30.

--no-cache

If the Cache::File module is available, server replies are cached in ~/.cache/Travel-Status-DE-HAFAS (or a path relative to $XDG_CACHE_HOME, if set) for 90 seconds. Use this option to disable caching. You can also use --cache to re-enable it.

--raw-json

Print unprocessed HAFAS response as JSON and exit. Useful for debugging and development purposes.

-s, --service service

Request arrivals/departures using the API provided by service, defaults to DB (Deutsche Bahn). See --list for a list of known services.

-t, --time hh:mm (monitor)

Request time. Must be specified in the selected HAFAS service's default time zone, see --list. Default: now.

-v, --via stopname|eva1,eva2,... (monitor)

Only show departures that pass by stopname (or arivals that have passed by stopname). If stopname is given as a list of numeric EVA IDs, only arrivals/departures with an exact EVA ID match are shown. Otherwise stopname is treated as a regular expression and matched against stop names.

-V, --version

Show version information and exit.

0 upon success, 1 upon internal error, 2 upon backend error.

None.

* Class::Accessor(3pm)

* LWP::UserAgent(3pm)

* The non-default services (anything other than DB) are not well-tested. Unlike DB, many of those do not return routes for stationboard entries.

* HAFAS does not provide real-time data for routes of stationboard entries. Hence, --via estimates the arrival time from scheduled departure and departure delay
