Rails gem to easily parse user name from email address.

Installation

Add this line to your application's Gemfile:

gem 'parse_name_from_email'

And then execute:

$ bundle

Or install it yourself as:

$ gem install parse_name_from_email

Configuration

You don't need to configure anything, but if you want to customize the behaviour, use the following snippet:

ParseNameFromEmail.configure do |config|
  # split email address with regexp
  config.regexp = /(?=[A-Z])|(?:([0-9]+))|\.|-|\?|!|\+|\;|\_/

  ## Recognizing plus parts in gmail addresses
  #
  # DEFAULT: true
  #
  # if TRUE:
  #   email address:  'example+something123@gmail.com'
  #   result name:    'Example (Something 123)'
  #
  # if FALSE:
  #   email address:  'example+something123@gmail.com'
  #   result name:    'Example'
  config.friendly_plus_part = true
end

Values in the above snippet are the default values.
