Build Status

Go/cgo interface to libpostal, a C library for fast international street address parsing and normalization.

Usage

To expand address strings into normalized forms suitable for geocoder queries:

package main

import (
    "fmt"
    expand "github.com/openvenues/gopostal/expand"
)

func main() {
    expansions := expand.ExpandAddress("Quatre-vingt-douze Ave des Ave des Champs-Élysées")

    for i := 0; i < len(expansions); i++ {
        fmt.Println(expansions[i])
    }
}

To parse addresses into components:

package main

import (
    "fmt"
    parser "github.com/openvenues/gopostal/parser"
)

func main() {
    parsed := parser.ParseAddress("781 Franklin Ave Crown Heights Brooklyn NY 11216 USA")
    fmt.Println(parsed)
}

Prerequisites

Before using the Go bindings, you must install the libpostal C library. Make sure you have the following prerequisites:

On Ubuntu/Debian

sudo apt-get install curl autoconf automake libtool pkg-config

On CentOS/RHEL

sudo yum install curl autoconf automake libtool pkgconfig

On Mac OSX

sudo brew install curl autoconf automake libtool pkg-config

Installing libpostal

git clone https://github.com/openvenues/libpostal
cd libpostal
./bootstrap.sh
./configure --datadir=[...some dir with a few GB of space...]
make
sudo make install

# On Linux it's probably a good idea to run
sudo ldconfig

Installation

For expansions:

go get github.com/openvenues/gopostal/expand

For parsing:

go get github.com/openvenues/gopostal/parser
