I am having no luck opening a text file that contains comma delimited data. I have tried some different ways and am having no luck at all. I can't even get a open file dialog to appear when I click a button.

I did not see any example of this in the sdk sample plugins.

Anyone able to help me out.

The file I am trying to load is "D:\Test\TestFile.txt".

If you did not escape the path's backslashes that may be part of the problem.

Some example code: 

local LrDialogs = import 'LrDialogs'

local LrFileUtils = import 'LrFileUtils'

local LrPathUtils = import 'LrPathUtils'



local file = 'C:\\temp\\Testfile1.txt'



if not LrFileUtils.isReadable(file) then

 local dialogresult = LrDialogs.runOpenPanel {

  title = 'Select input text file',

  allowsMultipleSelection = false,

  initialDirectory = LrPathUtils.parent(file)

 }

 file = dialogresult and dialogresult[1] or nil

end



if file and LrFileUtils.isReadable(file) then

 local collectedLines = {}

 for line in io.lines(file) do table.insert(collectedLines, line) end

 LrDialogs.message(table.concat(collectedLines, '\n'))

end
