Installation: A Smooth Ride into Ruby Gem Integration

Bundler: Streamlining Dependencies

    
      gem "ruby-gemini-ai"

Execute the command:

    
      $ bundle install

Gem Install: A Swift Installation Journey

Alternatively, install the gem:

    
      $ gem install ruby-gemini-ai

And elegantly require it in your code:

    
      require "gemini-ai"

Credentials: Opening the Gateway to Gemini AI

To embark on your Gemini AI adventure, credentials are your passport. Choose your path wisely:

Option 1: API Key (Generative Language API)

  1. Obtain an API Key from your Google Cloud project through the Google Cloud Console.
  2. Enable the Generative Language API service in your Google Cloud Console.

Option 2: Service Account Credentials File (Vertex AI API)

  1. Create a Google Cloud Project and a Service Account.
  2. Enable the Vertex AI API for your project.
  3. Generate credentials for your Service Account here and download a JSON file named google-credentials.json.

Option 3: Application Default Credentials (Vertex AI API)

Generate credentials using the gcloud CLI before local development:

    
      gcloud auth application-default login

Quickstart: Launching Your Gemini Journey

For a quick test, create a client with your API key:

    
      client = GeminiAi::Client.new(api_key: "your_gemini_api_key")

Configuration: Tailoring Gemini to Your Needs

Configure Gemini with Ruby using three options:

Option 1: API Key

    
      GeminiAi.configure do |config|
        config.api_key = ENV.fetch("GEMINI_API_KEY")
      end

Option 2: Service Account

    
      GeminiAi.configure do |config|
        config.service = 'vertex-ai-api'
        config.region = 'us-east4'
        config.file_path = 'google-credentials.json'
      end

Option 3: Default Credentials

    
      GeminiAi.configure do |config|
        config.region = 'us-east4'
        config.service = 'vertex-ai-api'
      end

Then create a client:

    
      client = GeminiAi::Client.new

Methods: Crafting Your Ruby Odyssey

stream_generate_content(contents, model)

  • Streams generated text in real-time.
  • contents (hash): User input and role information.
  • model (string): Optional model name (e.g., gemini-pro).
  • Returns an array of candidates objects with generated text and safety ratings.
    
      client = GeminiAi::Client.new
      contents = {
        contents: {
          role: 'user',
          parts: {
            text: 'Write a poem about the ocean.'
          }
        }
      }
      stream = client.stream_generate_content(contents, model: 'gemini-pro')

generate_content(contents, model)

  • Generates text in a single request.
  • contents (hash): User input and role information.
  • model (string): Optional model name (e.g., gemini-pro).
  • Returns a hash with generated text, safety ratings, and prompt feedback.
    
      result = client.generate_content(
        { contents: { role: 'user', parts: { text: 'hi!' } } }, model: 'gemini-pro'
      )

Development: Your Gateway to Ruby-Gemini Synergy

  1. Clone the repository.
  2. Run bin/setup to install dependencies.
  3. Use bin/console for interactive exploration.
  4. Run bundle exec rake install to install the gem locally.
