BR_GetCurrentTheme() function : how to use it ?

[cubic13]

Lua attempt : the following code works...

function gTheme()
local lThemePath = reaper.GetLastColorThemeFile()
reaper.ShowConsoleMsg("Theme info :".."\n"..lThemePath)
end

gTheme()

I get this, which is what was expected :

Theme info :
F:\Reaper5_Portable\ColorThemes\EyssinaFM.ReaperTh eme


The following code doesn't...

function gTheme()
local lThemePath, lThemeName = reaper.BR_GetCurrentTheme()
reaper.ShowConsoleMsg("Theme info :".."\n"..lThemePath.."\n"..lThemeName)
end

gTheme()

I just get this :

Theme info :


The problem is that I want only the name of the current theme, without path or extension, which is exactly what the BR_GetCurrentTheme function is supposed to provide, as a second return string. The 'ReaScript documentation' states this :

Lua: string themePathOut retval, string themeNameOut reaper.BR_GetCurrentTheme()
...
[BR] Get current theme information. themePathOut is set to full theme path and themeNameOut is set to theme name excluding any path info and extension

So :
1) What am I doing wrong ?
2) What does 'retval' means, actually ?
3) Additionaly, is there any actual examples of using this kind of functions somewhere as, even using this documentation, I'm not still sure about how to use the parameters call (again, the 'retval' one...) ?

Thanks for any help...


EDIT : I have the SWS extensions 2.8.3 installed and working, just in case...

A little bump...

I really need this one to work, so, if any lua guru could test the two pieces of code above and give me hints about what's happening...

reaper.BR_GetCurrentTheme still not working (SWS v2.11.0.0 pre-release 2019-12-07).

Do you guys just read the REAPER.INI (lastthemefn5=) to get this info?

EDIT Never mind, reading the ini did the trick, reason I needed it was so when I start REAPER the theme is set depending on time of day it is, used in my "__startup.lua" on Win10, ...

function GetFilename(filepath)
  local lastpos = (filepath:reverse()):find('\\')
  return (filepath:sub(-lastpos+1))
end

-- Set theme depending on hour of the day.
function SetTheme() 
  local fn = reaper.GetResourcePath()
  local _, curTheme = reaper.BR_Win32_GetPrivateProfileString('REAPER', 'lastthemefn5', '', fn .. '/REAPER.ini')
  
  local tm = (os.time())
  if tonumber(os.date("%H", tm)) < 17 then  -- Before 5pm use light theme
    fn = fn .."\\ColorThemes\\Eds_5.01_AGYR.ReaperThemeZip"
  else  -- after 5pm use dark theme
    fn = fn .."\\ColorThemes\\Eds_6.0.ReaperThemeZip" 
  end  
  -- load theme if not the current theme
  if GetFilename(curTheme) ~= GetFilename(fn) then
    reaper.OpenColorThemeFile(fn)
  end
end

BR_GetCurrentTheme reads the lastthemefn4 ini key (and removes the file extension). Looks like it was changed to lastthemefn5 for REAPER 5 and 6. Fixing!

EDIT: However that ini key does not exist unless the theme was changed at least once. It's better to use reaper.GetLastColorThemeFile instead (was added in 5.02).

THANKS! Not sure how I missed GetLastColorThemeFile, didn't even see it! Will give that a try.
