This fork publishes the Matrix nio changes needed by MindRoom on a release schedule independent of upstream matrix-nio. It follows active upstream development closely and carries a focused set of additions, primarily bot-oriented E2EE behavior, reliability fixes, and Simplified Sliding Sync support that are not yet available in an upstream release. Generally useful changes are kept suitable for upstream contribution, while fork-specific packaging and policy remain clearly separated.

mindroom-nio is a fork of nio, a multilayered Matrix client library. The distribution name is mindroom-nio; the Python import name remains nio. The underlying base layer doesn't do any network IO on its own, but on top of that is a full-fledged batteries-included asyncio layer using aiohttp. File IO is only done if you enable end-to-end encryption (E2EE).

Features

nio has most of the features you'd expect in a Matrix library, but it's still a work in progress.

  • ✅ transparent end-to-end encryption (EE2E)
  • ✅ encrypted file uploads & downloads
  • ✅ space parents/children
  • ✅ manual and emoji verification
  • ✅ custom authentication types
  • ✅ threading support
  • ✅ well-integrated type system
  • ✅ knocking, kick, ban and unban
  • ✅ typing notifications
  • ✅ message redaction
  • ✅ token based login
  • ✅ user registration
  • ✅ read receipts
  • ✅ live syncing
  • m.reactions
  • m.tags
  • 🟡 cross-signing support (fork addition; bot-scoped producer side — self-signs the account's own device so it stays usable under MSC4153. The verifier side, Secret Storage, and key backup are not implemented. See doc/cross-signing.md.)
  • ❌ server-side key backups (room key backup, "Secure Backup")
  • ❌ user deactivation (#112)
  • ❌ in-room emoji verification

Installation

To install mindroom-nio, simply use pip:

$ pip install mindroom-nio

Note that this installs mindroom-nio without end-to-end encryption support. The e2ee enabled version can be installed using pip:

$ pip install "mindroom-nio[e2e]"

Additionally, a docker image with the e2ee enabled version of nio is provided in the docker/ directory.
