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:

  • (ArgumentError) —

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

#interact_with_user ⇒ Object (private)

The interact_with_user method manages the interactive loop for user input and chat processing. It handles reading user input, processing commands, managing messages, and communicating with the Ollama server. The method supports command completion, prefilling prompts, socket input handling, and various chat features including embedding context and voice support. It processes user input through command handling, content parsing, and message formatting before sending requests to the Ollama server. The method also handles server socket messages, manages chat history, and ensures proper cleanup and configuration handling throughout the interaction.

#links ⇒ Set

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

The links set is memoized, meaning it will only be created once per object instance and subsequent calls will return the same Set instance.

Returns:

  • (Set) —

    A Set object containing all links associated with this instance

#manage_links(command) ⇒ Object (private)

The manage_links method handles operations on a collection of links, such as displaying them or clearing specific entries.

It supports two main commands: ‘clear’ and nil (default). When the command is ‘clear’, it presents an interactive menu to either clear all links or individual links. When the command is nil, it displays the current list of links with hyperlinks.

Parameters:

  • command (String, nil) —

    the operation to perform on the links

#setup_documents ⇒ Documentrix::Documents, NULL (private)

The setup_documents method initializes the document processing pipeline by configuring the embedding model and database connection. It then loads specified documents into the system and returns the configured document collection.

Returns:

  • (Documentrix::Documents, NULL) —

    the initialized document collection if embedding is enabled, otherwise NULL

#web(count, query) ⇒ String, Symbol (private)

Performs a web search and processes the results based on document processing configuration.

Searches for the given query using the configured search engine and processes up to the specified number of URLs. The processing approach varies based on the current document policy and embedding status:

  • **Embedding mode**: When ‘document_policy.selected == ’embedding’‘ AND `@embedding.on?` is true, each result is embedded and the query is interpolated into the web_embed prompt.

  • **Summarizing mode**: When ‘document_policy.selected == ’summarizing’‘, each result is summarized and both query and results are interpolated into the web_summarize prompt.

  • **Importing mode**: For all other cases, each result is imported and both query and results are interpolated into the web_import prompt.

Examples:

Basic web search

web('3', 'ruby programming tutorials')

Web search with embedding policy

# With document_policy.selected == 'embedding' and @embedding.on?
# Processes results through embedding pipeline

Web search with summarizing policy

# With document_policy.selected == 'summarizing'
# Processes results through summarization pipeline

Parameters:

  • count (String) —

    The maximum number of search results to process (defaults to 1)

  • query (String) —

    The search query string

Returns:

  • (String, Symbol) —

    The interpolated prompt content when successful, or :next if no URLs were found or processing failed
