Single File Deploy on Windows?

[Paul Dupuis]

Hi Dan,

That look to me like it should work. Here is my code below which does
work. That said, it works under 6.7.x and earlier. I have not tested my
code under LC7+. In my case I have only 1 external but I want to load
the correct one for OSX or Window.

The whole "put (there is a folder tExtFile) into tExtExists" is just a
safety check on someone removing the external or a failure of my
installer to install it.

on preOpenStack
   -- so substacks do not execute the code after this when opened
   if the owner of the target is not me then
      exit preOpenStack
   end if
   -- Load the XPDF Externals by loading an external stack, updating its
externals list, saving that stack and loading the stack
   put AppPath() into tExtPath
   switch the platform
      case "MacOS"
         put tExtPath & "XPDF.bundle" into tExtFile
         put (there is a folder tExtFile) into tExtExists
         break
      case "Win32"
         put tExtPath & "XPDF.dll" into tExtFile
         put (there is a file tExtFile) into tExtExists
         break
   end switch
   if (tExtExists is true)  then
      set the externals of the templateStack to tExtFile
      create invisible stack "XPDFViewer External Library"
      start using "XPDFViewer External Library"
   end if
 end preOpenStack

function AppPath
  put the fileName of me into tPath -- on OSX, file is report inside the
bundle <path>/MyApp.app/Contents/MacOS/MyApp
  set the itemDel to slash
  if (the platform is "MacOS") AND ("dev" is not in the environment) then
    get offset(".app/Contents/MacOS/",tPath)
    if it > 0 then -- 'filename' returned path to executable in package
      delete char it to len(tPath) of tPath
    end if
  end if
  delete last item of tPath
  if last char of tPath is not slash then put slash after tPath
  return tPath
end AppPath
