SimulatorFeaturesModule

Overview

The SimulatorFeaturesModule provides support to the mechanism client programs (viewers) use to request information about some features or properties of a region, for example BOM support, version of LSL/OSSL syntaxe, etc.
Viewer should ask for this information every time they see a new region. Unfortunately some of this may require that the viewer already created a avatar on that region. This information is send via HTTP with llsd xml encoding. some information specific to opensimulator is sent on a section (llsd map) OpenSimExtras

Configuration

Some parameters are constant and defined in code. Others are defined by specific, some optional, modules in fact, because reasons, this module is also optional.
This are also very dependent on the OpenSimulation version or flavor. Consequence of legacy decisions, unmanageable modularity and configurability, and blind selfish forking. More work is needed to provide consistence, in particular because some of this information is not optional at all if one likes to have viewers that do work.

OpenSim

OpenSimExtras items in particular are configured in several places through the code, even some modules may override what was defined by others. a few examples

[SimulatorFeatures]
 
   ; Override search service url
   SearchServerURI = "url to search service"
 
   ; Override destination guide url
   DestinationGuideURI = "url to destination guide"
 
   ; Override map service url
   ;(this may be set in one of several other locations, but we can use this to be consistent)
   MapTileURL = "url to map service"
 
[Chat]
 
   ; Distance in meters that ordinary chat should travel.  Default is 20m
   say_distance = 20
   ; Controls whether the chat module is enabled.  Default is true.
   enabled = true;
   ; Distance in meters that whispers should travel.  Default is 10m
   whisper_distance = 10
   ; Distance in meters that shouts should travel.  Default is 100m
   shout_distance = 100
