[Fixed] Problem with returning Numbers formatted as strings.

[smurfier]

When returning numbers that have been formatted as strings, they are returned as numbers, sans format.

Code: Select all

PROPERTIES = {}
function Initialize()
Try = 1
end
function Update()
Try = string.format("%02d",Try)
return Try
end

This should return 01 but instead returns 1.
When using print() or !SetOption, 01 is returned just fine.

This is due to the nature of Lua as it is a dynamically typed language, which is why something like this will work:

Code: Select all

function Update()
	local ret = string.format("%02d", 1)
	ret = ret + 1
	return ret -- returns 2
end

Prior to r885, Rainmeter 'requested' a textual value and a numerical value. This, however, rendered NumOfDecimals, Scale, AutoScale, and Percentual useless when using MeasureName=ScriptMeasure on STRING meters as Rainmeter simply used whatever textual value Lua gave.

r855 and later request a numerical value first and, if it is not available, request a textual value. Because "02" and 2 are analogous in Lua, they both return true in the 'get numerical value' stage.

Fixing this would require reverting the pre-r885 behavior and thus break NumOfDecimals, Scale, etc. I will discuss this matter with the other devs.

I made some changes for the next beta that should resolve things once and for all. return 1 is now treated differently from return "1" (and return "01", for the matter).

return 1 -> NumOfDecimals, Scale, etc. work.
return "1" -> NumOfDecimals, Scale, etc. do not work

This will care of your issue as well.

Thank you.

Here is a build with that fix for you to test Smurfie...

Works wonderfully.
