gem 'email_prefixer'

Configuration

All EmailPrefixer configuration can be customized using a standard Rails config initializer.

# config/initializers/email_prefixer.rb
EmailPrefixer.configure do |config|
  # custom configuration goes here
end

Some of the more common configuration options are listed here. See the source code and test suite for a full list of options.

application_name - Customize Application Name

The application name is automatically inferred from the Rails application class name and can be overridden via the application_name setting.

Example:

# config/initializers/email_prefixer.rb
EmailPrefixer.configure do |config|
  config.application_name = 'MyApp'
end

stage_name - Customize Environment Stage Name

The application environment/stage name is automatically inferred from the running Rails.env and it can be overridden via the stage_name setting.

Example:

# config/initializers/email_prefixer.rb
EmailPrefixer.configure do |config|
  config.stage_name = 'demo'
end

builder - Override the prefix format

Want to override the default format for the email prefix? Assign a custom proc to the builder setting like so:

Example:

# config/initializers/email_prefixer.rb
EmailPrefixer.configure do |config|
  config.builder = lambda do
    '**MyEmailPrefix** '
  end
end
