Extract string from file and store it

[DevoTaylor]

How can we extract the string path here at the bottom of the opt file as you can see in the image without the double quotes and store it in a text file or just store it in a variable.
I figure this can be done writing a lua script or using the string variables. But this is above my pay grade and so i ask for help.

From another topic i did manage to get this path using a vsscript a friend wrote. But i prefer to see other options as i hope lua coding will be easier.

Thanks...

Please zip the usercfg.opt file and attach the archive here.

i attached the UserCFG file.

Try this code:

function GetInstalledPackagesPath(sInputFile)
   -- the opt file is Unix formatted, i.e. does not end its lines with \r\n
   -- due to this, TextFile.ReadToTable() does not work without further changes
   local sOpt = TextFile.ReadToString(sInputFile);
   local sFound = string.match(sOpt, ".*InstalledPackagesPath[ \"]*([^\"%c]*).*");
   -- this will return the path without quotes, or nil if not found
   return(sFound);
end

-- use proper path to file, this line is for testing only
local sPathToOptFile = _SourceFolder .. "\\UserCfg.opt";

-- extract the desired path from config file
local sPathToPackages = GetInstalledPackagesPath(sPathToOptFile);

-- show result
if (sPathToPackages ~= nil) then
   Dialog.Message("", "Path to installed packages:\r\n" .. sPathToPackages, MB_OK, MB_ICONINFORMATION);
else
   Dialog.Message("", "Something went wrong!", MB_OK, MB_ICONEXCLAMATION);
end
