Crear un nou proveïdor de serveis

Els noms dels fitxers comencen amb el codi del país seguit d'un guió baix i un nom curt (i l'extensió, és clar). El nom del fitxer comença amb el codi de país o «international» o «unknown» seguit de «_» i un nom curt del proveïdor de serveis, per exemple, «de_db», «ch_sbb», «sk_atlas», «international_flightstats». El fitxer XML acaba amb «. xml».


El fitxer XML

Els enllaços als fitxers XML per al fitxer script que s'ha d'utilitzar i contindrà un «url pur», en aquest es pot inserir el nom de parada i altra informació.


El fitxer script

El fitxer script ha de contenir almenys una funció anomenada «parseTimetable», amb un argument. Tot el cos HTML anirà a l'script a través d'aquest argument. És llavors quan l'script analitza el document. Tot seguit us oferim una llista de funcions que criden al motor de dades PublicTransport per que s'analitzi un document:

  • parseTimetable( html ) (Usat per analitzar la sortida/arribada dels documents).
  • parseJourneys( html ) (Usat per analitzar els documents de viatge).
  • parsePossibleStops( html ) (Usat per analitzar els documents de suggeriment de parades).


Funcions auxiliars

Aquest és un objecte d'ajuda anomenat «helper», que pot ser utilitzat per l'script. Té les següents funcions:

  • trim( string ) (Removes ' ' from the beginning and the end of the given string)
  • stripTags( string ) (Removes all tags from the given string, ie. removing <...> or </...>)
  • camelCase( string ) (The first character of each word will be upper case, all others lower case)
  • extractBlock( string, beginString, endString ) (Returns the string between the first occurrence of beginString and the first occurrence of endString, or an empty string if beginString or endString couldn't be found in string. For example extractBlock("<b>Bold Text</b>", "<b>", "</b>") returns "Bold Text")
  • matchTime( string, formatString ) (Searches for a time string of the given format, eg. "hh:mm" and returns a list with two integers, the hour and the minute)
  • formatTime( hour, minute, formatString ) (Formats the given time using the given formatString)
  • duration( sTime1, sTime2, formatString ) (Returns the duration in minutes from sTime1 to sTime2, which are time strings in the given format)
  • addMinsToTime( sTime, minsToAdd, formatString ) (Parses the given time using the given formatString, adds minsToAdd minutes and format it again using formatString)
  • splitSkipEmptyParts( string, separator ) (Splits the given string using the given separator, while skipping empty parts)


Afegir sortides analitzades per al conjunt de resultats

Aquest és un objecte anomenat «timetableData» donat a l'script. Per afegir una sortida analitzada al conjunt de resultats feu alguna cosa com això:

// Add departure
 timetableData.clear();
 timetableData.set( 'TransportLine', 'N6' );
 timetableData.set( 'TypeOfVehicle', 'STR' );
 timetableData.set( 'Target', 'Bremen Hbf' );
 timetableData.set( 'DepartureHour', 1 );
 timetableData.set( 'DepartureMinute', 30 );
 result.addData( timetableData );

Això afegeix un punt de sortida de la línia de tramvia «N6», sortint a les 01:30 amb la destinació «Hbf Bremen».

  • Status (The current status of the departure/arrival. Currently only used for planes)
  • DepartureYear (The year of the departure, to be used when the year is separated from the date)
  • RouteStops (A list of stops of the departure/arrival to its destination stop or a list of stops of the journey from its start to its destination stop. If RouteStops and RouteTimes are both set, they should contain the same number of elements. And elements with equal indices should be associated (the times at which the vehicle is at the stops). For journeys RouteTimesDeparture and RouteTimesArrival should be used instead of RouteTimes)
  • RouteTimes (A list of times of the departure/arrival to its destination stop. If RouteStops and RouteTimes are both set, they should contain the same number of elements. And elements with equal indices should be associated (the times at which the vehicle is at the stops))
  • RouteTimesDeparture (A list of departure times of the journey. If RouteStops and RouteTimesDeparture are both set, the latter should contain one elements less (because the last stop has no departure, only an arrival time). Elements with equal indices should be associated (the times at which the vehicle departs from the stops))
  • RouteTimesArrival (A list of arrival times of the journey. If RouteStops and RouteTimesArrival are both set, the latter should contain one elements less (because the first stop has no arrival, only a departure time). Elements with equal indices should be associated (the times at which the vehicle arrives at the stops))
