mod_muc_markers

Introduction

This module adds an internal Prosody API to retrieve the last displayed message by MUC occupants.

Requirements

The clients must support XEP-0333, and the users to be tracked must be affiliated with the room.

Currently due to lack of clarity about which id to use in acknowledgements in XEP-0333, this module rewrites the id attribute of stanzas to match the stanza (archive) id assigned by the MUC server.

Oh yeah, and mod_muc_mam is required (or another module that adds a stanza-id), otherwise this module won’t do anything.
