Variable variables

[sh8an]

Hi all
i am new to rainmeter, so might be a stupid question.
simple case:
[Variables]
show=hide
hide=show
sysinfo.state=hide

then any meter, for example like this

Code: Select all

[Test.1]
Meter=STRING
x=0
y=70r
FontColor=#white#
Text=#sysinfo.state#
DynamicVariables=1
LeftMouseUpAction=!Execute [nircmd.exe win #sysinfo.state# title "System Information"][!SetVariable "sysinfo.state" "##sysinfo.state##"]

obviously it doesn't work. so my question is there any way to do variable variables with rainmeter?

ps. if escaped, the value stays escaped
thanks in advance

You could use the Script measure to achieve something like this.

Skin .ini file:

Code: Select all

[mLua]
Measure=Script
ScriptFile=Test.lua

...

[SomeMeter]
LeftMouseUpAction=!Execute [!CommandMeasure "mLua" "ToggleWindow()"]

Test.lua file (in same directory as skin .ini):

Code: Select all

function ToggleWindow()
	SKIN:Bang('!Execute [nircmd.exe win #sysinfo.state# title "System Information"]')

	local newState
	if SKIN:GetVariable('sysinfo.state') == 'hide' then
		newState = 'show'
	else
		newState = 'hide'
	end

	SKIN:Bang('!SetVariable sysinfo.state ' .. newState)
end

Does your example mean you don't need the Update and Initialize functions if you only use the script in !CommandMeasure Bangs?

[jsmorley]

Initialize() is run once when the skin is loaded / refreshed and Update() is run on each Update= of the skin. However, you can certainly call a Lua script that contains only a function using !CommandMeasure, and just have it execute the function and return.

Code: Select all

[Rainmeter]
Update=1000
DynamicWindowSize=1

[MeasureLua]
Measure=Script
ScriptFile="#CURRENTPATH#test.lua"
Disabled=1

[MeterDateTime]
Meter=String
FontSize=13
FontColor=255,255,255,255
SolidColor=0,0,0,1
Text=ClickMe
LeftMouseUpAction=!CommandMeasure MeasureLua "DateTime();"

function DateTime()

SKIN:Bang('!SetOption MeterDateTime Text """' .. os.date() .. '"""')

end -- function Test

An alternative method that I use in my skins:

Code: Select all

[Variables]
sysinfo.state=1

[MeasureSysInfoState]
Measure=Calc
Formula=#sysinfo.state#
Substitute="1":"show","0":"hide"
DynamicVariables=1

...

LeftMouseUpAction=!Execute [nircmd.exe win [MeasureSysInfoState] title "System Information"][!SetVariable sysinfo.state (1-#sysinfo.state#)]

Poiru's method is certainly cleaner, and easier to adapt to other cases. But this works great when all you need is to toggle a pair of values.
