Is it possible to change a theme color with Reascript?

[amagalma]

Hello!


What the title asks. And if yes, how?


Thanks!

I guess we still don't have the API to do it...

Which theme-color do you want to change?

My first guess would be, that you need to alter the Themename.ReaperTheme-file, who are regular ini-files.
Just use:
https://mespotin.uber.space/Ultrasch...eProfileString
https://mespotin.uber.space/Ultrasch...eProfileString
for that.

After that, you can simply reload the theme using: OpenColorThemeFile
https://mespotin.uber.space/Ultrasch...ColorThemeFile

Only works with unzipped themes, though.

I'm not familiar with the syntax or any limitations, but I would expect the new theme variables to be able to do this - if you had a theme written specifically to support it.

[Meo-Ada Mespotine]

Not with the colors, as they are not stored in the rtconfig-file, where the ThemeLayout-parameters are stored in.

Yay! It works! I didn't expected it to... Thank you very much!!


sample code

local filePath =  reaper.GetResourcePath() .. "\\ColorThemes\\test.ReaperTheme"
if not reaper.file_exists( filePath ) then
  reaper.MB( "Specified ColorTheme file path: " .. filePath, "ColorTheme does not exist!", 0 )
  return
end
local _, value = reaper.BR_Win32_GetPrivateProfileString( "color theme", "col_arrangebg", "does not exist", filePath )
reaper.ShowConsoleMsg("Old value of col_arrangebg: " .. value)
local newcolor =  reaper.ColorToNative( 56, 78, 112 )
reaper.BR_Win32_WritePrivateProfileString( "color theme", "col_arrangebg", tostring(newcolor) , filePath )
reaper.OpenColorThemeFile( filePath )
reaper.defer(function() end)

The idea is to make a script that could change all theme colors providing functions like Contrast, Brightness and Saturation, like image editors do. Or even provide a function to automatically make all the color scheme WCAGLevel AA/AAA compliant.



Of course all this needs a lot of work and a lot of time...

Looking forward to it

It seems that not all numbers in rtconfig under [color theme] are colors...

Yeah, this is a bit of a can of worms. But a more experienced programmer than I should be able to do something very useful if they're okay with:

1. The fact its only ever going to work on an unpacked theme, which is a bummer.
2. Picking through the minutiae of how colours reside in many places, and in differing colour formats. Some in the rtconfig, some in the .reapertheme file, and some hard written into bitmaps depending on the theme.

I would heartily encourage any efforts in this, however, because even a partial implementation could still be very useful.

[amagalma]

If I knew in which format is the value of every key in there, maybe I could do something... But it needs a lot of reverse engineering to find out.. And I can't understand why they should be in different formats and all over the place!.. :/
