Build Status

haskell-postal

This binding is in alpha state, expect more functionality to come soon. Currently it can only be used to do basic parsing and normalization.

Usage

{-# LANGUAGE OverloadedStrings #-}

import NLP.Postal

main :: IO ()
main = do
    setup
    setupParser
    setupLanguageClassifier

    apdo <- getAddressParserDefaultOptions
    pa <- parseAddress apdo "11 Wall Street New York, NY"
    print pa

    dno <- getDefaultNormalizeOptions
    xa <- expandAddress dno "11 Wall Street New York, NY"
    print xa

    tearDownLanguageClassifier
    tearDownParser
    tearDown

Installation

Before using the Haskell binding, 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=/usr/local/share/libpostal # Needs to have a few GBs of space
make
sudo make install

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

Installing the haskell-postal package

From source

Download the source from github, and use the cabal utility to install it:

git clone https://github.com/netom/haskell-postal
cd haskell-postal
cabal install

Cabal

Cabal can of course just fetch the package from Hackage:

cabal install haskell-postal

Stack

You can of course use stack to install the package, just replace "cabal install" with "stack install" anywhere above. Just make sure you try to find the installed package where the tool you use puts it.
