Referencing to a variable using a variable in its name :/

Post by Pflosch »

Hi,

I have variables x1 - x20 and a variable y which takes values from 1 to 20.
Now, I'd like to set variable z to the value of x1-20 depending on status of y.

[!setVariable z x#y#] sets z to the name of the variable, but of course not to the value... :/

Is there any syntax to achieve this, or do I need to take the long way with some IfMatch... ?

I'm not sure I quite understand, but I think this could help? [!SetVariable z #x1##y1#]

All variables usually are surrounded by #, but they have a different syntax if they're nested. If this isn't it, then maybe look at nested variables: https://docs.rainmeter.net/manual/variables/nesting-variables/

Hi and thanks,

Yeah, I looked into these, but didn't get to something working. Also your suggestion can't work here.

I want to set z to the value of any x1-x20, whereas the number to be picked is the y variable.(There's no y1 or y2)
So the used syntax cannot include a specific x1 or x13...

What's the use case?

Also, I'm kind of slow so if, for example, y=20 then x=20 and then z=2020??

Nope, example:
x1=5
x2=345
x3=65
x4=111
etc... these are user variables in an .inc file.

When y=3, I want to set z to the value of x3, when y=1 i want to set z to the value of x1.

Then I'm pretty sure you're going to have to use IfConditions...

Code: Select all


[MeasureY]
Measure=Calc
Formula=#y#
IfCondition=MeasureY=1
IfTrueAction=[!SetVariable z x[MeasureY]]
or

Code: Select all

IfTrueAction=[!SetVariable z x#y#]
Should work in theory, but it's very late so I didn't test it. Also, if this has to be dynamic, I'd probably find a way to "merge" x and y if possible (though it might not be)

Pflosch,
Like Halloyo said you would rather need here to use Nesting Variables.
If I got you right what you want to achive will look like this:
[!SetVariable z [#X[#Y]]]
Works for me:
