Quick start

Parsing cities

package main

import (
    "fmt"
    "github.com/mkrou/geonames"
    "github.com/mkrou/geonames/models"
    "log"
)

func main() {
    p := geonames.NewParser()
    
    //print all cities with a population greater than 5000
    err := p.GetGeonames(geonames.Cities5000, func(geoname *models.Geoname) error {
    fmt.Println(geoname.Name)
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }
}

Parsing alternames

package main

import (
    "fmt"
    "github.com/mkrou/geonames"
    "github.com/mkrou/geonames/models"
    "log"
)
func main() {
    p := geonames.NewParser()
    
    err := p.GetAlternateNames(geonames.AlternateNames, func(geoname *models.AlternateName) error {
        fmt.Println(geoname.Name)
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }
}

Parsing alphabetical list of archives

package main

import (
    "fmt"
    "github.com/mkrou/geonames"
    "github.com/mkrou/geonames/models"
    "log"
)
func main() {
    p := geonames.NewParser()
    
    err := p.GetGeonames("AD.zip", func(geoname *models.Geoname) error {
        fmt.Println(geoname.Name)
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }
    
    err = p.GetAlternateNames("alternames/AD.zip", func(geoname *models.AlternateName) error {
        fmt.Println(geoname.Name)
        return nil
    })
    if err != nil {
        log.Fatal(err)
    }
}
