Question regarding wildcards in events, Is my script ok?

[m1abrams]

Ok so I am pretty happy with EventGhost and I have only been using it for a couple of days. I can see a lot of things I can do with this. So far I have setup EG with SageTV to handle channel change events from SageTV for 2 different STB tuners using a USB-UIRT. Below is the script I used, I found the basis on the forum and tweaked it a bit. One thing I did was have it pad the channel number with zeroes to 3 digits because my tuners will change immediately on the 3rd digit instead of waiting a timeout period. I could have had it send and "Enter" command but that would only at best save me 1 ir transmit and require me to make sure NOT to send the Enter when I have 3 digits in the channel. Other thing I changed was I parse out the tuner info from the event so that I know which tuner to change the channel on.

I have two sets of marcos for IR transmits for numbers 0-9, 1 set for top tuner, 2 set for the bottom tuner.
The script is triggered on the event Main.* , SageTV sends an event to EG that is of this format.
Main.STB.STBTop.212

Where 212 is the channel number, and STBTop is the tuner. The other STB I was hoping I could use as the trigger event like Main.STB.* however that does not seem to work. Is that type of wildcard not possible? Right now with Main.* the python script actually triggers itself so I put in some logic in the script to try and finish "quickly" when it triggers it and is not the target event. Seems like having it trigger on such a wide target could cause some performance issues, particularly as I move forward and have more items that it may trigger on. Should I be concerned?

Anyhow my post is two parts:
1. Anything I should do to tweak my script?
2. Is their a way to define the event so that I do not trigger on so much? Right now my event is Main.*

Code: Select all

# get the event
event = eg.EventString

parts = event.split(".")
if len(parts) == 4 and parts[-3] == 'STB':
    tuner = parts[-2]
    channel = parts[-1]
    if channel.isdigit():
        channel = channel.zfill(3)
        # iterate over every digit 
        for digit in channel:
            # send an event for the digit
            eg.TriggerEvent(tuner + '-' + digit)

Bonus Question: I was thinking I have basically 2 copies of my ir transmit macros where I am only changing the output port for the USB-UIRT between the 2. Is their any way I could just have 1 set of macros and have it based on the event sent to the macro determine which port to send. Event could look like this Main.STBTransmit.* and send it Main.STBTransmit.Z1.2 Course this would also need a way to do wildcards at different levels.

It should work with two parts and a wildcard as well.

Code: Select all

eg.TriggerEvent(tuner + '-' + digit, prefix="prefix")

lets you choose your own prefix. You can also add an paylod

Code: Select all

eg.TriggerEvent(tuner + '-' + digit, prefix="prefix", payload=tuner + '-' + digit)

I just tested that wildcard at the second level again and it does not trigger.
I have event Main.STB.STBTop-212 and the event trigger is Main.STB.* note Main.* does work.

However modifing my script above to send a custom prefix for the channel change does reduce the number of times the Main.* is triggered.

is it possible to send a custom prefix with the command line event call? eventhost.exe -e ""?

1.
READ THIS before posting anything!
So get the latest beta.

2. eg.EventString is deprecated. You should use eg.event.string or eg.event.suffix instead

3. You can also use payloads to the -e option.
EventGhost.exe -e STBChangeChannel 24
Will give you always the event "Main.STBChangeChannel" and the script can use eg.event.payload[0] and will get the "24".

Thanks for the reply, I did not know about eventstring being deprecated. I have been trying to find all the docs I can on EG however I am not having much luck. Pretty much read everything on the wiki. Is there a better location for the docs?

I was using the latest beta when I posted the above thread.

Main.STB.* works here on Main.STB.STBTop-212 events.

[m1abrams]

I changed the script to use payloads that seems like a better solution all around. Also had to modify the script to use network listener since I changed SageTV to run as a service. It seems to be working very well now.

Oh an the second level wildcard is working, I have my Denon connected via serial and have an event trigger on DenonSerial.MV.* to cause the Volume to display via ShowOSD. Loving EG, thanks for the help and great app.
