aware-file-system 0.1.0

Filesystem watcher and indexing utilities for aware-cli aware_sdk workflows.

aware-file-system

aware-file-system is the change-detection layer behind aware-cli and the upcoming aware-sdk. It watches repository folders, persists lightweight indexes, and emits structured events so agents and automation can safely treat the filesystem as a source of truth.

Highlights

• Recursive watcher – polls directories, classifies create/update/delete events, and normalises them into JSON-ready payloads.
• Index snapshots – builds MsgPack-backed caches to accelerate large tree scans and cold starts.
• Pluggable handlers – send events to aware-cli’s summary state, your own async consumers, or a queue service by registering callbacks.
• Pure Python – easy to embed inside CI, long-running daemons, or custom tools.

Installation

pip install aware-file-system

Requires Python 3.12 or newer.

Quick start

import asyncio
from aware_file_system.config import Config, FileSystemConfig
from aware_file_system.models import ChangeType
from aware_file_system.watcher.file_system_watcher import FileSystemWatcher

async def main() -> None:
    config = Config(file_system=FileSystemConfig(root_path="docs/projects"))
    watcher = FileSystemWatcher(config, poll_interval=2.0)

    def handle(event) -> None:
        if event.change_type is ChangeType.MODIFIED:
            print(f"{event.path} updated ({event.checksum.sha256[:8]})")

    watcher.add_event_handler(handle)

    await watcher.start()
    try:
        await asyncio.sleep(10)
    finally:
        await watcher.stop()

asyncio.run(main())

Integrating with aware-cli

aware-cli summary \
  --project aware-sdk \
  --task cli-release-bundles \
  --watch-root docs/projects

The CLI wires aware-file-system under the hood to stream change events into its summary state. You can reuse the same configuration helpers (environment variables, YAML config) to point at other workspaces or embed the watcher inside your tooling.

Configuration reference

• AWARE_FILE_SYSTEM_ROOT – override the root directory that should be scanned.
• AWARE_FILE_SYSTEM_POLL_INTERVAL – polling cadence in seconds (default: 2.0).
• AWARE_FILE_SYSTEM_CACHE_DIR – location for MsgPack indexes (default: .aware/fs).
• aware_file_system.config.Config – Python API with sensible defaults and room for custom callbacks.

Testing

Run the suite from the repository root:

uv run --project libs/file_system pytest

Roadmap

• Optional native backends (inotify/FSEvents) for lower latency on supported platforms.
• Batched event delivery for agent-friendly payloads.
• Additional helpers to serialise change events into the Aware receipt format.
