Installation
The package is registered in the General registry and so can be installed at the REPL with
julia> using Pkg
julia> Pkg.add("GeoIP")Usage
Data files
You can use MaxMind geolite2 csv files downloaded from the site. Due to the MaxMind policy, GeoLite.jl does not distribute GeoLite2 files and does not provide download utilities. For automated download it is recommended to use MaxMind GeoIP Update program. For proper functioning of GeoIP.jl you need to download GeoLite2 City datafile, usually it should have a name like GeoLite2-City-CSV_20191224.zip.
Files processing and loading provided with load() call. Directory where data is located should be located either in ENV["GEOIP_DATADIR"] or it can be passed as an argument to load function. Zip file location can be passed as an argument or it can be stored in ENV["GEOIP_ZIPFILE"]. For example
using GeoIP
geodata = load(zipfile = "GeoLite2-City-CSV_20191224.zip", datadir = "/data")If ENV["GEOIP_DATADIR"] is set to "/data" and ENV["GEOIP_ZIPFILE"] is set to "GeoLite2-City-CSV_20191224.zip" then it is equivalent to
using GeoIP
geodata = load()Example
You can get the ip data with the geolocate function or by using []
using GeoIP
geodata = load(zipfile = "GeoLite2-City-CSV_20191224.zip")
geolocate(geodata, ip"1.2.3.4") # returns dictionary with all relevant information
# Equivalent to
geodata[ip"1.2.3.4"]
# Equivalent, but slower version
geodata["1.2.3.4"]geolocate form is useful for broadcasting
geolocate.(geodata, [ip"1.2.3.4", ip"8.8.8.8"]) # returns vector of geo data.Localization
It is possible to use localized version of geo files. To load localized data, one can use locales argument of the load function. To switch between different locales is possible with the help of setlocale function.
using GeoIP
geodata = load(zipfile = "GeoLite2-City-CSV_20191224.zip", locales = [:en, :fr])
geodata[ip"201.186.185.1"]

For example locales = [:en => r"Locations-en.csv%", :fr => r"Locations-fr.csv"]. By default, following locales are supported :en, :de, :ru, :ja, :es, :fr, :pt_br, :zh_cn.
Default locale, which is used in getlocale response can be set with the help of deflocale argument of the load function. For example, to get :fr locale by default
geodata = load(zipfile = "GeoLite2-City-CSV_20191224.zip", locales = [:en, :fr], deflocale = :fr)Acknowledgements
