Go/cgo interface to libpostal, a C library for fast international street address parsing and normalization.
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)
}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
For expansions:
go get github.com/openvenues/gopostal/expand
For parsing:
go get github.com/openvenues/gopostal/parser
go test github.com/openvenues/gopostal/...
