referer-parser Ruby library

This is the Ruby implementation of referer-parser, the library for extracting search marketing data from referer (sic) URLs.

The implementation uses the shared 'database' of known referers found in referers.yml.

Installation

Add this line to your application's Gemfile:

gem 'referer-parser'

And then execute:

$ bundle

Or install it yourself as:

$ gem install referer-parser

Usage

To include referer-parser:

require 'referer-parser'

To create a parser

Parsers are created by default with the set of included referers but they can also be loaded from another file(s) either during or after instantiation

Creating and modifying the parser:

# Default parser
parser = RefererParser::Parser.new

# Custom parser with local file
parser = RefererParser::Parser.new('/path/to/other/referers.yml')

# From a URI
parser = RefererParser::Parser.new('http://example.com/path/to/other/referers.yml')

# Default referers, then merge in a set of custom internal domains
parser = RefererParser::Parser.new
parser.update('/path/to/internal.yml')

# Default referers, then add your own internal domain inline instead of from a file
parser = RefererParser::Parser.new
parser.add_referer('internal', 'SnowPlow', 'snowplowanalytics.com')

# Clear all of the existing referers
parser.clear!

Using a parser

The parser returns a hash of matching data if it can be found including search terms, medium, and nicely-formatted source name. If there is no match, :known will be false.

parser = RefererParser::Parser.new
parser.parse('http://www.google.com/search?q=gateway+oracle+cards+denise+linn&hl=en&client=safari')
  # => {
    :known=>true,
    :uri=>"http://www.google.com/search?q=gateway+oracle+cards+denise+linn&hl=en&client=safari",
    :source=>"Google",
    :medium=>"search",
    :term=>"gateway oracle cards denise linn"
  }
