Config display_rooms Question

[Andy M.]

  Another question about the mh.ini parameters display_rooms and display_apps:

  I have multiple displays in one room (ie. a SqueezeBox and a MythTV frontend) and sometimes want all displays to display the same message. So I assumed I can use the display_rooms parameter for this? Or does the display_rooms parameter actually only define individual devices, and not all the devices in one room?

  Currently I am grouping displays via apps. Everything works beautifully at the moment. I am just enquiring if I had missed the method for grouping displays in one room together before linking them to applications. That is, in the setup below I would change so that "kitchen" meant the Slim Device and MythTV devices together?

  display_rooms = lounge  => schema=osd.basic address=slimdev-slimserv.Lounge  device=xpl,
                  kitchen => schema=osd.basic address=slimdev-slimserv.Kitchen device=xpl,
                  kitchen_myth => device=mythosd

  display_apps = alert   => display_rooms=lounge|kitchen duration=58,
                 caution => display_rooms=lounge|kitchen duration=30,
                 temp    => display_rooms=lounge|kitchen duration=30,
                 info    => display_rooms=lounge|kitchen duration=10

  If the answer is no, then I don't see it as a problem. I just want to use the feature if it exists......

  ALSO, what is the function of display_groups?

Andy.

No--you want to use display_groups for this.  Yes, I know--it's
confusing.  Essentially, display_groups contains the definitions of
groups of devices--which might be mapped to a room.  And, display_rooms
contains definitions of devices.

That is correct.

display_groups= kitchen => kitchen_squeezebox kitchen_myth, lounge =>
loung_squeezebox

I'm not personally using display_groups at the moment and don't recall
just how tested the above syntax is.  So, shout if you encounter problems.

  Time to "shout" about display_groups!

  I have been looking at display_groups and could not get them to work, as per Gregg's example above.

  Looking through the code, I don't think they ever would have worked as intended. I searched the MH code distribution, the Wiki and Google for examples of people using display_groups and have found none. Gregg's example syntax makes the most sense for usage of the parameter, so I propose we modify mh to work as such with one small change. I suggest we use a delimiter other than space. This will conform with the "room" delimiter used in the parameter display_rooms.

  An example of the format would be:

display_groups = lounge=>lounge_slim|lounge_myth, kitchen=>kitchen_slim|kitchen_myth


  The changes required are:

Index: mh
===================================================================
--- mh  (revision 1477)
+++ mh  (working copy)

     for my $room (split(/[,;|]/,$parms{display_rooms})) {

-           for my $group_room (keys %groups) {

                 my %room_parms = &parse_func_parms($display_rooms{$group_room});
                 %{$targets{$group_room}} =%room_parms;


  If nobody objects, I will make the change in SVN.

Andy.

I'm not surprised.  I had wondered about that as well.  Likely, the
addition had just not been tested.

Looks good to me.
