[Feature] RGB to HEX and vice versa!

[DeathByChocolate]

I have created a configuration skin that allows you to change the colours of another skin, and I want to add RGB4.exe plus an InputText field where you can input either the RGB or HEX colour. What I would love and appreciate is if it were possible to add a bang that detects the colour model of a variable and converts it to the opposite, and vice versa.

e.g: MainColour=140,160,200 turns into MainColour=#8ca0c8 or the other way round!

Hope this is possible without having to implement a third-party application...

It is. You don't even have to use a lua code, just simple Rainmeter measures.
This first code converts an RGB code to HEX:

Code: Select all

[Rainmeter]
Update=-1
AccurateText=1
DynamicWindowSize=1

[Variables]
ColorCode=140,160,200

[MeasureR]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^(\d{1,3}),(\d{1,3}),(\d{1,3})$":"\1"

[MeasureG]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^(\d{1,3}),(\d{1,3}),(\d{1,3})$":"\2"

[MeasureB]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^(\d{1,3}),(\d{1,3}),(\d{1,3})$":"\3"

[MeasureRemainderR1]
Measure=Calc
Formula=( [MeasureR] % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureQuotientR1]
Measure=Calc
Formula=(( [MeasureR] - MeasureRemainderR1 ) / 16 )

[MeasureRemainderR2]
Measure=Calc
Formula=( MeasureQuotientR1 % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureRemainderG1]
Measure=Calc
Formula=( [MeasureG] % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureQuotientG1]
Measure=Calc
Formula=(( [MeasureG] - MeasureRemainderG1 ) / 16 )

[MeasureRemainderG2]
Measure=Calc
Formula=( MeasureQuotientG1 % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureRemainderB1]
Measure=Calc
Formula=( [MeasureB] % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureQuotientB1]
Measure=Calc
Formula=(( [MeasureB] - MeasureRemainderB1 ) / 16 )

[MeasureRemainderB2]
Measure=Calc
Formula=( MeasureQuotientB1 % 16 )
Substitute="10":"a","11":"b","12":"c","13":"d","14":"e","15":"f"

[MeasureConverted]
Measure=String
String=#[MeasureRemainderR2][MeasureRemainderR1][MeasureRemainderG2][MeasureRemainderG1][MeasureRemainderB2][MeasureRemainderB1]
DynamicVariables=1

[MeterCode]

Y=0
FontColor=220,220,220

Padding=25,5,25,5

The second code converts vice-versa: a HEX code to RGB:

Code: Select all

[Rainmeter]

[MeasureR2]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^#(.)(.)(.)(.)(.)(.)$":"\2","a":"10","b":"11","c":"12","d":"13","e":"14","f":"15"

[MeasureG1]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^#(.)(.)(.)(.)(.)(.)$":"\3","a":"10","b":"11","c":"12","d":"13","e":"14","f":"15"

[MeasureG2]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^#(.)(.)(.)(.)(.)(.)$":"\4","a":"10","b":"11","c":"12","d":"13","e":"14","f":"15"

[MeasureB1]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^#(.)(.)(.)(.)(.)(.)$":"\5","a":"10","b":"11","c":"12","d":"13","e":"14","f":"15"

[MeasureB2]
Measure=String
String=#ColorCode#
RegExpSubstitute=1
Substitute="^#(.)(.)(.)(.)(.)(.)$":"\6","a":"10","b":"11","c":"12","d":"13","e":"14","f":"15"

[MeasureR]
Measure=Calc
Formula=( 16 * [MeasureR1] + [MeasureR2] )
DynamicVariables=1

[MeasureG]
Measure=Calc
Formula=( 16 * [MeasureG1] + [MeasureG2] )
DynamicVariables=1

[MeasureB]
Measure=Calc
Formula=( 16 * [MeasureB1] + [MeasureB2] )
DynamicVariables=1

[MeasureConverted]
Measure=String
String=[MeasureR],[MeasureG],[MeasureB]
DynamicVariables=1

[MeterCode]
Meter=STRING
MeasureName=MeasureConverted

So much talent in one reply xD

And it works like a charm,thanks Balala, I'll use it from now on until a shorter or simpler version is implemented.

Glad if you like it and find useful.
