A Question regarding Variables

Eggplant Functional
1

Hello,

I am new to Eggplant and SenseTalk, and now I got stuck.

I try to address a variables content as a global variables’ name - but how?

I pass a parameter to a function, eg “button35” and store it in a variable myCurrentBtn.

set myCurrentBtn to item one of paramters

Now I want to access the already set global variable “button35”. This gets set in a different script.
This works:


global button35.(global env.variable)

This does not:


global myCurrentBtn.(global env.variable)

I need to use a variable cause “button35” will be passed to this function and might be something else…

Please Help

Hi–

Has myCurrentBtn been declared as a global variable? You either need to declare it as global at the top of the script:

global myCurrentBtn

or inline:

set global myCurrentBtn to item one of paramters

Hope this helps!

hard to explain what I mean, be gentle

the variable myCurrentBtn is local, its content is “button35” which is passed into this function.

Now my problem is, that whatever is passed to this function eg “button35” is also the name of a global variable. So if I pass “button35” to the function there will be a global button35 out there.
So I kind of need a “pointer” to myCurrentBtns’ content - to adress this content as a global var…

I really hope You can follow my idea

To access the contents of a variable whose name is held in another variable you can use the value() function:

set button35 to "OK"
set myCurrentButton to "button35"
put myCurrentButton -- shows "button35"
put value(myCurrentButton) -- shows "OK"

Or, for a global variable:

set global button35 to "OK"
set myCurrentButton to "button35"
put myCurrentButton -- shows "button35"
put value("global" && myCurrentButton) -- shows "OK"

Is that close to what you’re looking for?

Another approach you might consider for this sort of thing would be this: Instead of storing values in a lot of different global variables for each button, store the values in a single global property list with keys for each button. So then you’d have something like:

params myCurrentButton
global allButtonValues -- this is a property list that has a "button35" key
put allButtonValues.(myCurrentButton)

Hopefully one of those approaches will get you where you want to go.
