Mailbox (lingmessage.mailbox)

File-system backed message store. Each thread is a directory under root/threads/, with one JSON file per message and a thread.json header.

from lingmessage.mailbox import Mailbox

mailbox = Mailbox(root=Path("~/.lingmessage"))

Methods

Method	Signature	Description
post	(message: Message) -> Message	Write a message to its thread directory
open_thread	(sender, recipients, channel, topic, subject, body, ...) -> tuple[ThreadHeader, Message]	Create a new discussion thread
reply	(thread_id, sender, recipient, subject, body, ...) -> Message	Add a reply to an existing thread
load_thread_header	(thread_id: str) -> ThreadHeader \| None	Load thread metadata
load_thread_messages	(thread_id: str) -> tuple[Message, ...]	Load all messages in a thread
list_threads	(channel?, status?, participant?) -> tuple[ThreadHeader, ...]	List threads with optional filters
get_summary	() -> dict	Get stats: total threads, messages, by channel/status

---

LingBus (lingmessage.lingbus)

SQLite WAL-backed message bus. Experimental — Mailbox remains the primary backend.

from lingmessage.lingbus import LingBus

bus = LingBus(bus_dir=Path("~/.lingmessage"))
# or as context manager:
with LingBus(bus_dir=path) as bus:
    ...

Methods

Method	Signature	Description
open_thread	(topic, sender, recipients, channel?, subject?, body?) -> tuple[str, str]	Returns (thread_id, message_id)
post_reply	(thread_id, sender, recipient, body, ...) -> str	Returns message_id. Raises ValueError if thread not found.
poll	(recipient, since_rowid?, limit?) -> list[BusMessage]	Get new messages for a recipient
get_thread	(thread_id) -> list[BusMessage]	Get all messages in a thread
list_threads	(status?) -> list[dict]	List all threads with optional status filter
ack	(message_id, member) -> bool	Mark message as acknowledged. Returns False if not found.
get_max_rowid	(recipient) -> int	Get highest rowid for polling checkpoint
stats	() -> dict	Returns {threads, messages, unacked}
sync_from_mailbox	(mailbox: Mailbox) -> int	Import threads from Mailbox. Idempotent. Returns count.
close	() -> None	Close the database connection

BusMessage dataclass

@dataclass
class BusMessage:
    rowid: int
    message_id: str
    thread_id: str
    sender: str
    recipient: str
    message_type: str
    channel: str
    subject: str
    body: str
    timestamp: str
    reply_to: str
    metadata: dict[str, str]
    acked_by: list[str]

Adapters (lingmessage.adapters)

Bridge external Ling-project data into the Mailbox.

Adapter	Method	Source
LingFlowAdapter(mailbox)	post_daily_reports() -> list[Message]	$LINGFLOW_ROOT/data/reports/
LingClaudeIntelAdapter(mailbox)	post_digests() -> list[Message]	$LINGCLAUDE_ROOT/data/intel/
LingYiBriefingAdapter(mailbox)	post_briefings() -> list[Message]	$LINGYI_ROOT/data/briefings/

Environment variables (with defaults): - LINGFLOW_ROOT — defaults to ~/LingFlow - LINGCLAUDE_ROOT — defaults to ~/LingClaude - LINGYI_ROOT — defaults to ~/LingYi

---

Compat (lingmessage.compat)

Bidirectional conversion between LingYi's lingmessage.py format and LingMessage.

from lingmessage.compat import import_lingyi_discussion, import_lingyi_store, export_to_lingyi_format

# Import a single LingYi discussion dict
threads = import_lingyi_discussion(mailbox, lingyi_dict)

# Import all discussions from LingYi store directory
ids = import_lingyi_store(mailbox, lingyi_root=Path("~/.lingmessage"))

# Export LingMessage messages to LingYi format
lingyi_dict = export_to_lingyi_format(messages)

---
