boarding-pass

boarding-pass is a partial Go port of georgesmith64/bcbp with some inspiration from martinmroz/iata_bcbp.

The main difference between the libraries is that boarding-pass only offers users the ability to decode the data in a Bar Coded Boarding Pass into structured data.

From an implementation perspective, georgesmith64/bcbp is written in JavaScript and thus has the flexibility to create the structured data on the fly. martinmroz/iata_bcbp is written in Rust and uses impl to expose the data through method calls. boarding-pass aims to build the BCBP struct on the fly as efficiently as possible and return that to the caller.

boarding-pass supports up to version 8 of the IATA Resolution 792 spec. Although, both georgesmith64/bcbp and martinmroz/iata_bcbp support up to version 6, information on version 7 and 8 were gleaned from this issue.

Installation

go get github.com/jandauz/boarding-pass

Getting started

package main

import (
	"fmt"

	"github.com/jandauz/boarding-pass"
)

func main() {
	const s = "M1DESMARAIS/LUC       EABC123 YULFRAAC 0834 326J001A0025 100"
	b, err := bcbp.FromStr(s)
	if err != nil {
		fmt.Println(err)
	}
	fmt.Println("Format Code:", b.FormatCode)
	fmt.Println("NumberOfLegsEncoded:", b.NumberOfLegsEncoded)
	fmt.Println("PassengerName:", b.PassengerName)
	fmt.Println("ElectronicTicketIndicator:", b.ElectronicTicketIndicator)
	fmt.Println("OperatingCarrierPNRCode:", b.Legs[0].OperatingCarrierPNRCode)
	fmt.Println("FromCityAirportCode:", b.Legs[0].FromCityAirportCode)
	fmt.Println("ToCityAirportCode:", b.Legs[0].ToCityAirportCode)
	fmt.Println("OperatingCarrierDesignator:", b.Legs[0].OperatingCarrierDesignator)
	fmt.Println("FlightNumber:", b.Legs[0].FlightNumber)
	fmt.Println("DateOfFlight:", b.Legs[0].DateOfFlight)
	fmt.Println("CompartmentCode:", b.Legs[0].CompartmentCode)
	fmt.Println("SeatNumber:", b.Legs[0].SeatNumber)
	fmt.Println("CheckInSequenceNumber:", b.Legs[0].CheckInSequenceNumber)
	fmt.Println("PassengerStatus:", b.Legs[0].PassengerStatus)
	// Output:
	// Format Code: M
	// NumberOfLegsEncoded: 1
	// PassengerName: DESMARAIS/LUC
	// ElectronicTicketIndicator: E
	// OperatingCarrierPNRCode: ABC123
	// FromCityAirportCode: YUL
	// ToCityAirportCode: FRA
	// OperatingCarrierDesignator: AC
	// FlightNumber: 0834
	// DateOfFlight: 2021-11-22
	// CompartmentCode: J
	// SeatNumber: 001A
	// CheckInSequenceNumber: 0025
	// PassengerStatus: 1
}

Notes

boarding-pass currently does not attempt to interpret the data except forNumberOfLegsEncoded, DateOfFlight, and DateOfBoardingPassIssuance.

NumberOfLegsEncoded is a uint. This is necessary for determing how many Legs to process.

Both DateOfFlight and DateOfBoardingPassIssuance are strings formatted using RFC 3339 full-date format. There is currently no attempt to determine if the values are realistic dates e.g. an unrealistic date would be on that is far ahead in the future.
