[SOLVED] Lua execute windows command in Lightroom SDK

Lua execute windows command in Lightroom SDK

I’m porting my lightroom plugin to Windows. On MacOSX everything works perfect.

Now i’m stuck with one command, Normally I try to use as mutch of LR commands because they are compatible with both OS’s.

cmdRunExifTool = string.format('cd "'..NewTargetDir..'"  &&  '.._PLUGIN.path..'\\bin\\win\\exiftool.exe '..(optionOverwrite or "")..' optionAppend=".\\C+F-'..NewJson..'" .') 
LrTasks.execute(cmdRunExifTool)

I have added a pop-up window with the command and it show me this:

cd "c:\Users\patri\Pictures\TEST-IMAGES\FF690-KTMX-000869\_scans\positives\C+F_exiftool" && c:\Users\patri\Documents\AnalogeFotografie.lrplugin\bin\win\exiftool.exe optionAppend=".\C+F-mybeelden" .

But nothing happens. If I run this on the command line it works !

Solution

For WIN_ENV you have to surround the whole cmdline with double-quotes (")

function cmdlineQuote()
    if WIN_ENV then
        return '"'
    elseif MAC_ENV then
        return ''
    else
        return ''
    end
end

cmdRunExifTool = 
    cmdlineQuote() .. 
    string.format('cd "'..NewTargetDir..'"  &&  '.._PLUGIN.path..'\\bin\\win\\exiftool.exe '..(optionOverwrite or "")..' optionAppend=".\\C+F-'..NewJson..'" .')  ..
    cmdlineQuote()
LrTasks.execute(cmdRunExifTool)
