Defined in:

Overview

ChannelManager starts and supervises IM platform adapter threads. When an inbound message arrives it:

1. Resolves (or auto-creates) a Session bound to this IM identity
2. Retrieves the WebUIController for that session
3. Creates a ChannelUIController and subscribes it to the WebUIController
4. Runs the agent task via run_agent_task (same as HttpServer)
5. Unsubscribes the ChannelUIController when the task finishes

Thread model: each adapter runs two long-lived threads (read loop + ping). ChannelManager itself is non-blocking — call #start from HttpServer after the WEBrick server has started.

Session binding: the first message from an IM identity automatically creates a new session and binds it. Users can use /bind <session_id> to switch to an existing WebUI session instead. Bindings are stored in the session registry as :channel_keys => Set of channel key strings. WebUI sessions are persisted by HttpServer — channel adds no extra persistence.

    /<skill> <args> - invoke a skill directly
    /bind <n|session_id> - switch to a session (use /list to see numbers)
    /unbind - remove binding
    /stop - interrupt current task
    /status - show current binding
    /list - show recent sessions

Constructor Details

#initialize(session_registry:, session_builder:, run_agent_task:, interrupt_session:, channel_config:, binding_mode: :chat_user) ⇒ ChannelManager

Returns a new instance of ChannelManager.

Parameters:

  • session_registry (Clacky::Server::SessionRegistry)
  • session_builder (Proc) —

    (name:, working_dir:) => session_id — from HttpServer

  • run_agent_task (Proc) —

    (session_id, agent, &task) — from HttpServer

  • interrupt_session (Proc) —

    (session_id) — from HttpServer

  • channel_config (Clacky::ChannelConfig)
  • binding_mode (:user | :chat | :chat_user) (defaults to: :chat_user) —

    how to map IM identities to sessions. :chat_user (default) — one session per (chat, user) pair. Most natural:

    private chat = that user's session; in a group each
user has their own session; the same user across
different groups keeps those contexts separate.

    :chat — one session per chat (all users in a group share it). :user — one session per user (merges DMs and all groups).

#adapter_for(platform) ⇒ Object?

Return the currently-live adapter for a given platform, or nil if none running. Thread-safe — acquires @mutex to read from @adapters.

Parameters:

  • platform (Symbol, String)

#known_users(platform) ⇒ Array<String>

Return a list of known user IDs for the given platform. Collected from every message that has been processed since the server started. Weixin stores context_tokens keyed by user_id; feishu/wecom track chat_ids via the session binding table in the registry.

Parameters:

  • platform (Symbol, String)

Returns:

  • (Array<String>)

#send_to_user(platform, user_id, message) ⇒ Hash?

If no token is found the message cannot be delivered and nil is returned.

For Feishu and WeCom the chat_id / user_id is sufficient — no token needed.

Parameters:

  • platform (Symbol, String) —

    e.g. :weixin, :feishu, :wecom

  • user_id (String) —

    IM user identifier

  • message (String) —

    plain-text (or markdown) message to send

Returns:

  • (Hash, nil) —

    adapter result hash, or nil on failure
