Setting meter text with Lua?

[Kaelri]

As to the second bit, you can update the skin with SKIN:Bang('!Update') just as you have it, but it doesn't make any sense to do that from Lua. EVERYTHING in the Lua script that talks to Rainmeter happens when the script is done and returns to Rainmeter, and thus on the next Update anyway... You might want to consider something like:

LeftMouseUpAction=!Execute [!CommandMeasure "MeasureLua" "nextCard()"][!Update]

Which should execute the Lua and immediately update.

Just a small quibble, but I don't think this is true. If I have a button that runs a script function with SKIN:Bang('!Update') in it, I get an instantaneous response even when the skin has Update=-1. I'm not sure why this wasn't working in the original script, but I guess it's a moot point now. :)

You may be right. I know that things that talk to Rainmeter in the Update() section of the .lua are ALL executed when the Lua returns control to the skin after all of Update() has run, which is why you can't put a loop in a .lua file like:

for 1 = 1, 255 do
SKIN:Bang('!SetOption MeterOne FontColor 255,255,255,'..i)
end

and get a nice fade effect on a meter. The only Bang that you will see Rainmeter execute is the last one, which will be 255.

However, if you use !CommandMeasure to directly call a Lua function, it will no doubt return as soon as that function is done and in that case an !Update in the Lua may well happen before the normal Update= in [Rainmeter]. Even on a regular Measure=Script that runs a Lua file that doesn't have all that much work to do in Update() may well return before the next Update= and an !Update bang in it may well make things snappier.

On balance, in this case I think I still like the [!Update] after the command measure in the skin, as it at worst accomplishes the same thing, and feels cleaner than remote controlling the update from Lua.... But then I like cornflakes, and you eat rice crispies.

Oh, sweet!
I finally got it to add cards (Yeah, been working at it since the last post =/)!
Trying to synchronize the Lua and Skin was hard ><
(Even with the help you gave me)

But I can't get implement a method to edit flash cards now =/
I've been trying to for a while but it won't work right.

Stuff updates..
But it's the wrong card that gets updated =/
I go to the first card and edit it.
But the second or last card gets updated instead.

So, card.cur has to be wrong; the thing is, I added a Calc measure to track the value of card.cur but it's correct.
I just don't see why it updates wrongly =/

InputText is a plugin measure, which means that you can't use dynamic variables (such as your #card.cur#) with it. You could get around that by sending the command through Lua. For example:

Code: Select all

Command3      =!CommandMeasure MeasureLua "Edit3('$UserInput$')"

Code: Select all

function Edit3(sUserInput)
   local DECK.cur   = SKIN:GetVariable("card.cur")
   SKIN:Bang('!WriteKeyValue Variables "fCard'..DECK.cur..'" "'..sUserInput..'" "#CURRENTPATH#\variables.inc"')
end

Huh, it says that it can't find "MeasureLua"

!CommandMeasure [MeasureLua] not found

But I'm pretty sure it's there =/

Code: Select all

Command3      =!CommandMeasure MeasureLua "Edit3('$UserInput$')" #CURRENTCONFIG#

[FatherCode]

Oh, thanks, I made it:

Code: Select all

	Command3		=!CommandMeasure "MeasureLua" "editCardFront('$InputText$')" #CURRENTCONFIG#
	Command4		=!CommandMeasure "MeasureLua" "editCardBack('$InputText$')" #CURRENTCONFIG#

And for the button:

Code: Select all

	LeftMouseUpAction	=!Execute [!CommandMeasure "MeasureInputText" "ExecuteBatch 3-4"]

However, the InputText box doesn't appear.
The Plugin just calls editCardFront() and editCardBack() and passes the string "$InputText$"
So my flash card becomes updated to "$InputText" =/

[Kaelri]

You always use $UserInput$ for the InputText plugin.

Code: Select all

	Command3		=!CommandMeasure "MeasureLua" "editCardFront('$UserInput$')" #CURRENTCONFIG#
	Command4		=!CommandMeasure "MeasureLua" "editCardBack('$UserInput$')" #CURRENTCONFIG#

The parameter name in Rainmeter doesn't need to be the same as the parameter name in Lua. As long as the function (e.g.) editCardFront receives a parameter, it will be defined as whatever it's called there. :)

[FatherCode]

*facepalm*
Oh, my gawd.
Thanks, Kaelri =)


All this while..
It was.. That..
I think I need to be in a corner for a bit =/

[EDIT]
The InputText Plugin has a "H" option, that sets its height, right?
And I can't set this with a formula, right?
Like: (#skin.height#-(#skin.padding#*2)-#btn.height#)
It only seems to work if I input literals =/
(Guess I'll hack it with Lua ><)

[EDIT=2]
I tried but failed =/

Code: Select all

	--Define some locals
		local skin_w	= tonumber(SKIN:GetVariable("skin.width"))
		local skin_h	= tonumber(SKIN:GetVariable("skin.height"))
		local skin_p	= tonumber(SKIN:GetVariable("skin.padding"))
		local btn_w	= tonumber(SKIN:GetVariable("btn.width"))
		local btn_h 	= tonumber(SKIN:GetVariable("btn.height"))
	--Set the size of the InputText Box
		SKIN:Bang	("!SetOption MeasureInputText H "..(skin_h-(skin_p*2)-btn_h))

I could just use a literal but then, I would have to recalculate the size every time I want to change my skin's width and height =/
