gtfsparser

Dieser Inhalt wurde automatisch aus der README-Datei des go gtfsparsers generiert und liegt daher nicht auf Deutsch vor.

Das Projekt liegt auf github zur Nutzung und Mitentwicklung bereit. Der Großteil der Entwicklung fand im Rahmen meiner Tätigkeit bei bei geOps statt.

A complete*, easy to use parsing library for GTFS data. Implemented in go. Accepts folders containing GTFS files and ZIPs. Feeds are validated during parsing. ID references are transformed into pointer references where appropriate.

This is a fork from the gtfsparser I developed at geOps, containing some minor improvements. Because of some changes to member types, this is not a drop-in replacement for the geOps gtfsparser.

Usage

feed := gtfsparser.NewFeed()
error := feed.Parse("sample-feed.zip")

See feed.go for exported fields.

Example

Parsing of the GTFS example feed:

import (
    "github.com/patrickbrosi/gtfsparser"
    "fmt"
)

func main() {
    feed := gtfsparser.NewFeed()

    feed.Parse("sample-feed.zip")

    fmt.Printf("Done, parsed %d agencies, %d stops, %d routes, %d trips, %d fare attributes\n\n",
        len(feed.Agencies), len(feed.Stops), len(feed.Routes), len(feed.Trips), len(feed.FareAttributes))

    for k, v := range feed.Stops {
        fmt.Printf("[%s] %s (@ %f,%f)\n", k, v.Name, v.Lat, v.Lon)
    }
}

Output

Done, parsed 1 agencies, 9 stops, 5 routes, 11 trips, 2 fare attributes
