This tutorial will create a skin showing the number of seconds from the start of the year in binary with Rainmeter and Lua. Lua can be used with Rainmeter to load and execute skins. We’ll make a binary clock that shows the number of seconds elapsed from the beginning of the year. The two source files are here.
First, create a new skin called BinaryTime. Then, create an .INI file named
binaryLine.ini for the skin. Inside it, put the following code:
[Rainmeter] Update=1000 [Variables] Radius=10 Spacing=5 FullColor=50,50,250,200 EmptyColor=140,140,140,100 [CircleStyle] W=(#Radius#*2+#Spacing#) H=(#Radius#*2+#Spacing#) X=R Y=0 LineLength=#Radius# LineColor=#FullColor# Solid=1 AntiAlias=1 [mDayOfYear] Measure=Time Format=%j ; The day of the year, from 1-366 inclusive [mHours] Measure=Time Format=%H ; The hour, from 0-23 inclusive [mMinutes] Measure=Time Format=%M ; The minute, from 0-59 inclusive [mSeconds] Measure=Time Format=%S ; The second, from 0-59 inclusive [mFinalDecimalCalc] Measure=Calc Formula=(mDayOfYear - 1)*24*60*60+mHours*60*60+mMinutes*60+mSeconds ; Calculates the seconds since the beginning of the year, in base 10 [mLua] Measure=Script ScriptFile=line.lua [m1] Meter=Roundline MeterStyle=CircleStyle X=0 [m2] Meter=Roundline MeterStyle=CircleStyle ; ... ; Include [m3] to [m24] here ; ... [m25] Meter=Roundline MeterStyle=CircleStyle
When you load the skin, you should see something like this line of 25 blue circles:
To convert the decimal representation to binary, we’ll need to make a Lua script. In the same folder as
binaryLine.ini, make a Lua file
line.lua. Inside put the following code:
function Initialize() mDecimalTime = SKIN:GetMeasure("mFinalDecimalCalc") end
Initialize function runs when the skin is first loaded. The second line creates a variable
mDecimalTime and sets it to the measure
[mFinalDecimalCalc]. Now, add this code:
function Update() decimalTime = mDecimalTime:GetValue() for i = 24, 0, -1 do if decimalTime - 2^i > 0 then decimalTime = decimalTime - 2^i SKIN:Bang("!SetOption m"..(25-i).." LineColor #FullColor#") else SKIN:Bang("!SetOption m"..(25-i).." LineColor #EmptyColor#") end end end
Update function is called every time the skin is refreshed (in our case, every second) The second line in this code sets a new variable
decimalTime to the current value of
[mFinalDecimalCalc]. Then, it iterates backwards through each circle meter and sets the meter’s color.
#FullColor corresponds to a binary value of 1 and
#EmptyColor to 0.
The binary 1000110110011011110111001 corresponds to 18560953 seconds in decimal, which means it’s approximately 215 days from the beginning of the year (early August).
