Overview

A chat client for interacting with Ollama models through a terminal interface.

The Chat class provides a complete command-line interface for chatting with language models via the Ollama API. It handles configuration management, message history, document processing, web searching, and various interactive features including voice output, markdown rendering, and embedding capabilities.

Examples:

Initializing a chat session

chat = OllamaChat::Chat.new(argv: ['-m', 'llama3.1'])

Starting an interactive chat

chat.start

Constructor Details

#initialize(argv: ARGV.dup) ⇒ Chat

Initializes a new OllamaChat::Chat instance with the given command-line arguments.

Sets up the chat environment including configuration parsing, Ollama client initialization, model selection, system prompt handling, document processing setup, and history management. This method handles all the bootstrapping necessary to create a functional chat session that can communicate with an Ollama server and process various input types including text, documents, web content, and images.

The initialization process includes parsing command-line options using Tins::GO for robust argument handling, setting up the Ollama client with configurable timeouts (connect, read, write), validating Ollama API version compatibility (requires >= 0.9.0 for features used), configuring model selection based on command-line or configuration defaults, initializing system prompts from files or inline content, setting up document processing pipeline with embedding capabilities through Documentrix::Documents, creating message history management through OllamaChat::MessageList, initializing cache systems for document embeddings, setting up voice support and image handling for multimodal interactions, enabling optional server socket functionality for remote input, and handling configuration errors with interactive recovery mechanisms.

Parameters:

  • argv (Array<String>) (defaults to: ARGV.dup) —

    Command-line arguments to parse (defaults to ARGV.dup)

Raises:

  • (RuntimeError) —

    If the Ollama API version is less than 0.9.0, indicating incompatibility with required API features

Instance Attribute Details

#document_policy ⇒ OllamaChat::StateSelector (readonly)

The document_policy reader returns the document policy selector for the chat session.

Returns:

  • (OllamaChat::StateSelector) —

    the document policy selector object that manages the policy for handling document references in user text

def document_policy
  @document_policy
end

#documents ⇒ Documentrix::Documents (readonly)

Returns the documents set for this object, initializing it lazily if needed.

The documents set is memoized, meaning it will only be created once per object instance and subsequent calls will return the same Documentrix::Documents instance.

Returns:

  • (Documentrix::Documents) —

    A Documentrix::Documents object containing all documents associated with this instance

end

#messages ⇒ OllamaChat::MessageList (readonly)

Returns the messages set for this object, initializing it lazily if needed.

The messages set is memoized, meaning it will only be created once per object instance and subsequent calls will return the same OllamaChat::MessageList instance.

Returns:

#ollama ⇒ Ollama::Client (readonly)

The ollama reader returns the Ollama API client instance.

Returns:

  • (Ollama::Client) —

    the configured Ollama API client

end

#think_mode ⇒ OllamaChat::StateSelector (readonly)

The think_mode reader returns the think mode selector for the chat session.

Returns:

  • (OllamaChat::StateSelector) —

    the think mode selector object that manages the thinking mode setting for the Ollama model interactions
