If you're running python, all you have to do is 'pip install usaddress' and you're up and running.
I then wrote a quick python script to convert usaddress output to a standard format, like this:
[Optional Name, though you really shouldn't pass it]
Address line 1
[Optional Address Line 2]
City
State
Zipcode
#
Here's the usaddr.py script (python 3.x):
#!/usr/bin/python
import sys
import usaddress
for addr in sys.argv[1:]:
try:
c = usaddress.tag(addr)[0]
l = []
breakfields = [
'Recipient',
'BuildingName',
'LandmarkName',
'CornerOf',
'USPSBoxType',
'AddressNumber',
'AddressNumberPrefix',
'PlaceName',
'StateName',
'ZipCode'
]
multikill = {
'AddressNumberPrefix' : [ 'AddressNumber' ]
}
for k,v in c.items():
if k in breakfields:
breakfields.remove(k)
if k in multikill:
for mk in multikill[k]:
if mk in breakfields:
breakfields.remove(mk)
l = [i for i in l if i]
if l != []:
print(' '.join(l))
l = [v]
else:
l.append(v)
l = [i for i in l if i]
if l != []:
print(' '.join(l))
print('#')
except usaddress.RepeatedLabelError as e :
print('Error: cannot parse address')
Since I'm running a LAMP stack on one of my servers that happens to have python also installed, I wrote a quick usaddr.php script to implement an API:
< ?php
foreach (explode('&', $_SERVER['QUERY_STRING']) as $chunk) {
$param = explode("=", $chunk);
if ($param) {
$cmd = urldecode($param[0]);
$arg = urldecode($param[1]);
if ($cmd === 'addr') {
$command = 'python /path/to/your/script/usaddr.py ' . escapeshellarg($arg);
$output = shell_exec($command);
echo $output;
}
}
}
?>
So this meant I could access http://myserver.com/myapi/usaddr.php?addr=[address to reformat] from other apps (like FileMaker) to do address reformatting.
