That's actually a good point!

But, if possible, I would like to keep them as a two separate variables.

For now, height and iconSize could be the same values, but for some cases I could give some variations on them.

  4.         ["height"] = 35,
  5.         ["point"] = {"CENTER", UIParent, "CENTER", 250, -200},
  6.         ["iconSize"] = "height",
  7.         ["spacing"] = 2,
  8.     },
  9. }

then when using the configuration do something like:

Lua Code:
  1. local height = G["castbar"]["player"]["height"]
  2. local iconSize = G["castbar"]["player"]["iconSize"]
  3. if iconSize=="height" then
  4.         iconSize = height
  5. end
  6. castbar:SetHeight(height)
  7. icon:SetSize(iconSize,iconSize)
If in the future you decide to set iconSize to lets say 50, you just need to change the configuration value from "height" to 50, the code the uses the configuration will still work.
This could be the possible solution!

So... there is no such a straight-forward way to achieve this, right?
