mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.
# Introduction
This module allows you to make one or more MUCs as accessible to local users only.
# Details
Local users (anyone on the same server as the MUC) are granted automatic
membership when they first join the room. Users from other servers are
denied access (even if the room is otherwise configured to be open).
# Configuring
## Enabling
``` {.lua}
Component "rooms.example.net" "muc"
modules_enabled = {
"muc_local_only";
}
```
## Settings
Specify a list of MUCs in your config like so:
```
muc_local_only = { "my-local-chat@conference.example.com" }
```
# Compatibility
Requires Prosody 0.11.0 or later.
# Future
It would be good to add a room configuration option.
