summary: 'XEP-0313: Message Archive Management for MUC'
...
Introduction
============
This module logs the conversation of chatrooms running on the server to
Prosody's archive storage. To access them you will need a client with
support for [XEP-0313: Message Archive Management] **version 0.5** or
a module such as [mod_http_muc_log].
Usage
=====
First copy the module to the prosody plugins directory.
Then add "mam\_muc" to your modules\_enabled list:
``` {.lua}
Component "conference.example.org" "muc"
modules_enabled = {
"mam_muc",
}
```
mod\_mam\_muc needs an archive-capable storage module, see
[Prosodys storage documentation][doc:storage] for how to select one.
The store is called "muc\_log".
Configuration
=============
Logging needs to be enabled for each room in the room configuration
dialog.
``` {.lua}
muc_log_by_default = true; -- Enable logging by default (can be disabled in room config)
muc_log_all_rooms = false; -- set to true to force logging of all rooms
-- This is the largest number of messages that are allowed to be retrieved when joining a room.
max_history_messages = 20;
```
Compatibility
=============
------- --------------------------------------------
trunk Use mod\_muc\_mam (included with Prosody)
0.10 Works partially, only XEP-0313 version 0.5
0.9 Does not work
0.8 Does not work
------- --------------------------------------------
Prosody trunk (after April 2014) has a major rewrite of the MUC module,
allowing easier integration, but this module is not compatible with
that.
