mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel)
Otherwise the global event handlers accumulate, one added each time
logging is reoladed, and each invocation of the signal or event triggers
one dump of each created ringbuffer.
# Introduction
Many projects have a support room accessible via a web chat. This module
allows making the URL to such a web chat discoverable via the XMPP
service discovery protocol, enabling e.g. [search
engines](https://search.jabbercat.org/) to index and present these.
# Configuring
## Enabling
``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
"muc_webchat_url";
}
```
## Settings
The URL is configured using the in-band MUC room configuration protocol.
The module can optionally be configured to give all public (not
members-only, hidden or password protected) rooms gain a default value
based on a template:
``` {.lua}
muc_webchat_baseurl = "https://chat.example.com/join?room={node}"
```
The following variables will be subsituted with room address details:
`{jid}`
: The complete room address, eg `room@muc.example.com`ยท
`{node}`
: The local part (before the `@`) of the room JID.
`{host}`
: The domain name part of the room JID.
