# Caller

Gem which helps initialize class instance with `.call` method.

```

.call(*args) => #new.call(*args)

```

## Installation

Add this line to your application's Gemfile:

```ruby

gem 'caller'

```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install caller

## Usage

Do you have some code like this?

```ruby

module Service

  def call(*args)

    new(*args).call

  end

end

class Printer

  extend Service

  def initialize(text)

    @text = text

  end

  def call

    @text

  end

end

```

Let's replace it with `caller`

```ruby

class Printer

  extend Caller

  def call(text)

    text

  end

end

Printer.call('Say caller')

```

## caller_for

Assign other alias for the constructor with `caller_for` method

```ruby

class Printer

  extend Caller

  caller_for :print

  def print(text)

    text

  end

end

Printer.print('Say caller')

```

## Development

After checking out the repo, run `bin/setup` to install dependencies. Then, run `rake spec` to run the tests. You can also run `bin/console` for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run `bundle exec rake install`. To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and tags, and push the `.gem` file to [rubygems.org](https://rubygems.org).
