This is the Erlang implementation of ua-parser. The implementation is a NIF wrapper around uap-cpp.
Getting started:
Dependencies
In order to be able to compile properly make sure the following deps are available on your machine:
- re2
- yaml-cpp (0.5 API)
On Mac Os you can install those using brew :
brew install re2 yaml-cppOn Ubuntu:
sudo apt-get install libyaml-cpp-dev libre2-devIntegration
The application is compatible with both rebar or rebar3. Add erluap as a rebar dependency to your project:
{deps, [
{erluap, ".*", {git, "https://github.com/silviucpp/erluap.git", "master"}},
}.
Update user agents regexes
The file using user agents regular expressions is part of uap-core. In order to update this file you can modify
UAP_CORE_REV inside build_deps.sh
API
Parse as records
Records are described in erluap.hrl as follow:
-record(device, {
device_type :: device_type(),
family :: value(),
model :: value(),
brand :: value()
}).
-record(agent, {
family :: value(),
version_major :: value(),
version_minor :: value(),
version_patch :: value(),
version_patch_minor :: value()
}).The parsing method returns a tuple as follow {Device::#device{}, Os::#agent{}, Browser::#agent{}} :
erluap:parse(<<"Mozilla/5.0 (iPhone; CPU iPhone OS 12_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148">>).
{{device,mobile,<<"iPhone">>,<<"iPhone">>,<<"Apple">>},
{agent,<<"iOS">>,<<"12">>,<<"2">>,null,null},
{agent,<<"Mobile Safari UI/WKWebView">>,null,null,null,null}}Parse as proplist
There is possible to parse the result as proplist using erluap:parse_as_proplist/1 :
erluap:parse_as_proplist(<<"Mozilla/5.0 (iPhone; CPU iPhone OS 12_2 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Mobile/15E148">>).
[{device,[{device_type,mobile},
{family,<<"iPhone">>},
{model,<<"iPhone">>},
{brand,<<"Apple">>}]},
{os,[{family,<<"iOS">>},
{version_major,<<"12">>},
{version_minor,<<"2">>},
{version_patch,null},
{version_patch_minor,null}]},
{browser,[{family,<<"Mobile Safari UI/WKWebView">>},
{version_major,null},
{version_minor,null},
{version_patch,null},
{version_patch_minor,null}]}]Check if a device is a crowler
In order to check if a device is a crowler (spider) you cam check is device family is equal with <<"Spider">> or just use
the method erluap:is_spider/1
Tests
In order to run the tests just use make ct from project root after you compiled and got the deps using rebar
