I want the Erling code to determine the length of the visitor nickname

I use the Ejabberd server . How do I add the option to specify the number of characters of the visitor nickname within the room configuration ?

This small patch limits the length of the occupants nicknames to 5 characters or less. It is not configurable, simply edit the source code:

I see no option to restrict the length of a room occupant nickname.
