My motivation for creating this extraction is the dearth of high-quality, flexible, street address parsing gems available to the Ruby community. After digging into Ruby-Toolbox looking for alternatives I came up with tools based on the Perl GEO::StreetAddress::US such as street_address. The street_address gem ended up being much to restrictive for my needs and my continued searching brought me to the Geocoder::US gem. Regrettably the constraints of needing a SQLite3 database for proper geocoding added overhead to my simple needs. I simply need to parse addresses that may, or may not, be "complete" or "well-formed". Thus Indirizzo was born.
require 'Indirizzo' Indirizzo::Address.new("some address")
#new takes a string or a (pre-parsed address) hash as its first parameter and
an options hash.
In the case of a string specifying and address, Indirizzo will do its best to parse any matter of string, though results can be complicated. In the cases where things are complicated the various attributes in Indirizzo do their best to keep all reasonable answers in an array which you can inspect. (ex: "1600 Pensylvania Washington", in this case the state is difficult to determine so both "Pennsylvania" and "Washington" are returned for City and Street)
In the case of the pre-parsed address hash the keys of the
hash be symbols matching the various Address fields in Indirizzo (specifically
Currently only one option is supported for the option hash:
:expand_streets- a boolean which determines if "1 First St"'s street parameter is expanded into "1 st", "first st", and "one st" or simply left as "first st"
Indirizzo is a direct derivative of Geocoder::US 2.0
Geocoder::US 2.0 was based on earlier work by Schuyler Erle on a Perl module of the same name. You can find it at http://search.cpan.org/~sderle/.
Geocoder::US 2.0 was written by Schuyler Erle, of Entropy Free LLC, with the gracious support of FortiusOne, Inc. Please send bug reports, patches, kudos, etc. to patches at geocoder.us.
