Dynamic variables

[pos 22]

Hi

 

Anyone that knows how to create and use a dynamic variable like this in Fibaro-LUA?

It does not work in Fibaro sandbox as _G cannot be used. 

 

Anyone with an idea?

 

 

Tnx

Are you going to read the current month?
If so, I'll do this way.

Well, yes - or

if you don't need to do translation.

if you want more compact code that (I think) will be easier to maintain.

According answering some gurus here 

_G not supported - Fibaro runtime always create own environment for scenes or VSs and working there. You can’t share vars in  LUA processes like scenes or VD

@RH_Dreambox The "month" was just an example and had NO meaning at all. The question was about creating new variables at runtime in code, and not about month of the year.

 

@10der Intention was not to share vars between VDs and/or scenes. Intention was to create and use new vars dynamically as runtime in my VD.

I can see _G is not supported. But I have found a way to do it now... If I read a table I can dynamically create vars to use.

 

EXAMPLE:

But my intention is to read global predef variables (instead of "testTable") through the API like  HOST:GET('/api/globalVariables/LTCFG_ROOMS'); that hold arrays of enumvalues values like this: <ROOM>:<LIGHT_ARRAY_IDS>:<TIMER>:<AUTO_OFF>

 

In the loop reading these enumvalues and split them at ":" I create new variables on the fly i memory with these as their values to use later on in my VD service.

 

But as said, I found a work around  It seem this is the only way to do it as "_G" cannot be used.

Yes. What you really want then is just a table of key-value pairs that you store in a global variable using fibaro:setGlobal once it has been encoded into a json string, and then retrieved using fibaro:getGlobal().

Essentially the same as _G, but you have to do it yourself
