printing a global variable shows some unexpected numbers

[Neo Andersson 185]

Can anyone tell me please, what are those numbers behind by global variable?

 

["192.168.100.7","192.168.100.23","192.168.100.47","192.168.100.96"] 1728491927

 

This is driving me crazy..all json.decodes fails..whatever i do, i get that number behind. I can change the content of any variable some numbers shows up behind.

@Neo Andersson

unix timestamp it seems like

You are printing the result from som function that returns 2 values. 

Ex. fibaro.getValue usually returns the value and the timestamp

Lua's print will print all values returned from the last argument, so

print(fibaro.getValue(55,'value')) will print the value and the timestamp.

To get rid of the multiple values and only return the first value you can enclose the expression in parenthesis.

print((fibaro.getValue(55,'value'))) will only print the first value.

@jgab Got the answer  👆

 

Or @Neo Andersson was pointing to globals 🤔

so he isnt using the sintax fibaro.getvalue i guess? 🤔

@jgab thanks for the answer, but this is crazy..how can this be possible..i am using this approach like in 50 quickapps. Many of them is running years and i never got that problem..

 

Having this json string in a global variable SPEAKERS {"RobSpeaker":{"ip":"192.168.100.23","mac":"cc:f4:11:ce:51:5c"},"HubSpeaker":{"ip":"192.168.100.72","mac":"ac:67:84:83:46:75"},"OfficeSpeaker":{"ip":"192.168.100.96","mac":"ac:67:84:ec:90:a5"},"HallSpeaker":{"ip":"192.168.100.47","mac":"d4:f5:47:19:70:4b"},"LivingroomSpeaker":{"ip":"192.168.100.7","mac":"d4:f5:47:16:be:72"}} and using

always fails...

 

So i need to always use paparenthesiss?? for any fibaro.getValue or fibaro.getGlobalVariable etc ?

 

Here nust be something else behind the scenes..

 

Like lterally i was using print(hub.getVariable(<somestringvariable>)) in milion ocasions and never had anything like that

@jgab Wait,,,can this be just because i am using eventLib?

Just to get me to some Psychiatric Institute this approach, that failied a few minutes ago

doesnt fail. It works again, and i did nothing with the variables...nothing

What is setting thoose globals? is it that what sets it with a timestamp? 🤔

Or is the timestamp still there?

when printing out without parenteshis it is still there, but for some reason the json.decode doesnt fail at this moment

when i just open the web ui and grab the value of that variable, i can not see the timestamp, only when printing it out

Hmm strange 🤔
I havent used alot of globals, but never experienced it 🤔

 

   

    local test = hub.getGlobalVariable("EVENTS")

    print(hub.getGlobalVariable("EVENTS"))  --- gives timestamp

    print("test:",hub.getGlobalVariable("EVENTS")) --- gives timestamp

    print("test:",(hub.getGlobalVariable("EVENTS"))) --- no timestamp

    print(test) --- no timestamp

    print("test:",test) --- no timestamp

and this a strange thing you found here 😅

 

@jgab why is it like this? sometimes it print without timestamp sometimes with? 

 

[Neo Andersson 185]

the major issue for me is, that is not consistant with json.decode(), like all the afternooon i was struggling to find why the decode doesnt work..then i found that it should be probably these extra timestamp numbers (that are invisible in web ui), later i tried it again and the same code works. Same variable, same code, and now works..Driving me crazy...I have so many quickapps running on customer's systems, and i naver ever had any issue with getValue or getGlobalVariable functions. I have never ever got timestamps written, or json.decode fails...

Yea that is kinda scary 😲

So, computers are rational and relative predictable - so it's usually in one own's code...  

This will fail

The reason is that fibaro.getGlobalVariable return the value and the timestamp when the variable was changed so json.decode gets the arguments

Unfortunately, json.decode can take an extra second argument being a table with decoding options. However, now it gets an integer (timestamp) and crashes.

Wrapping it in parentheses makes it work

@jgab so Jan doesn that mean, that every time i do somehing like

the variables speakers and sensorstate can hold some extra timestemp? Or it goes only for cases when i am redaing a json string and i want to decode it?

No, a variable can only hold one value.

Functions can return multiple values. 

So when fibaro.getGlobalVariable(...) returns 2 values they are passed as 2 arguments to json.decode(...)

However, when you do

the second value gets dropped, as variables can only hold one value...
