Overview

A class that serves as the main entry point for interacting with the Ollama API.

The Client class provides methods to communicate with an Ollama server, handling various API endpoints such as chat, generate, create, and model management commands. It manages configuration settings like base URL, timeouts, and output streams, and supports different response handlers for processing API results.

Examples:

Initializing a client with a base URL

client = Ollama::Client.new(base_url: 'http://localhost:11434')

Configuring a client using a configuration object

config = Ollama::Client::Config[base_url: 'http://localhost:11434']
client = Ollama::Client.configure_with(config)

Constructor Details

#initialize(base_url: nil, output: $stdout, connect_timeout: nil, read_timeout: nil, write_timeout: nil, debug: nil, user_agent: nil) ⇒ Client

The initialize method sets up a new client instance with the specified configuration parameters.

This method is responsible for initializing a new Ollama::Client instance by processing various configuration options including the base URL, output stream, timeouts, and debug settings. It handles default values for the base URL by falling back to an environment variable, validates that the base URL is a valid HTTP or HTTPS URI, and extracts SSL verification settings from query parameters. The method also sets up instance variables for all configuration options, making them available for use in subsequent client operations.

Parameters:

  • base_url (String, nil) (defaults to: nil) —

    the base URL of the Ollama API endpoint, defaults to nil

  • output (IO) (defaults to: $stdout) —

    the output stream to be used for handling responses, defaults to $stdout

  • connect_timeout (Integer, nil) (defaults to: nil) —

    the connection timeout value in seconds, defaults to nil

  • read_timeout (Integer, nil) (defaults to: nil) —

    the read timeout value in seconds, defaults to nil

  • write_timeout (Integer, nil) (defaults to: nil) —

    the write timeout value in seconds, defaults to nil

  • debug (Boolean, nil) (defaults to: nil) —

    the debug flag indicating whether debug output is enabled, defaults to nil

  • user_agent (String, nil) (defaults to: nil) —

    the user agent string to be used for API requests, defaults to nil

Instance Attribute Details

#base_url ⇒ URI (readonly)

The base_url attribute reader returns the base URL used for making requests to the Ollama API.

Returns:

  • (URI) —

    the base URL configured for API requests

Instance Method Details

#commands ⇒ Array<String>

The commands method retrieves and sorts the documented commands available in the client.

This method extracts all command annotations from the class, sorts them by their names, and returns an array containing only the command names in alphabetical order.

Returns:

  • (Array<String>) —

    an array of command names sorted alphabetically

# File 'lib/ollama/client.rb', line 126

def commands
  doc_annotations.sort_by(&:first).transpose.last
end

#help ⇒ Object

The help method displays a list of available commands to the output stream.

This method retrieves the sorted list of documented commands from the client and outputs them as a comma-separated string to the configured output stream. It is typically used to provide users with information about which commands are available for execution through the client interface.

def help
  @output.puts "Commands: %s" % commands.join(?,)
end

#inspect ⇒ String Also known as: to_s

The inspect method returns a string representation of the client instance.

This method provides a human-readable description of the client object, including its class name and the base URL it is configured to use.

Returns:

  • (String) —

    a string representation in the format “#<Ollama::Client@localhost:11434>”

#request(method:, path:, handler:, body: nil, stream: nil) ⇒ Ollama::Client

The request method sends an HTTP request to the Ollama API and processes responses through a handler.

This method constructs an HTTP request to the specified API endpoint, handling both streaming and non-streaming responses. It manages different HTTP status codes, including success (200), not found (404), and other error cases. The method also includes comprehensive error handling for network-related issues such as socket errors and timeouts.

Parameters:

  • method (Symbol) —

    the HTTP method to use for the request (:get, :post, :delete)

  • path (String) —

    the API endpoint path to request

  • handler (Ollama::Handler) —

    the handler object responsible for processing API responses

  • body (String, nil) (defaults to: nil) —

    the request body content, if applicable

  • stream (TrueClass, FalseClass, nil) (defaults to: nil) —

    whether to enable streaming for the operation

Returns:

  • (Ollama::Client) —

    returns the client instance itself after initiating the request

#ssl_verify_peer? ⇒ TrueClass, FalseClass

The ssl_verify_peer? method checks whether SSL peer verification is enabled.

This method returns a boolean value indicating if the client should verify the SSL certificate of the Ollama server during communication. It converts the internal SSL verification flag to a boolean value for easy checking.

Returns:

  • (TrueClass, FalseClass) —

    true if SSL peer verification is enabled, false otherwise
