 Dear List,
 Hello,

 In the following function defined in Fontsampler for quick overview
of all fonts in a directory hierarchy, I need the output to be sorted
 alphabetically. How can I do that?

 function dirtree(dir)
  assert(dir and dir ~= "", "directory parameter is missing or empty")
  if string.sub(dir, -1) == "/" then
    dir=string.sub(dir, 1, -2)
  end

  local function yieldtree(dir)
    for entry in lfs.dir(dir) do
      if not entry:match("^%.") then
        entry=dir.."/"..entry
          if not lfs.isdir(entry) then
            coroutine.yield(entry,lfs.attributes(entry))
          end
          if lfs.isdir(entry) then
            yieldtree(entry)
          end
      end
    end
  end

  return coroutine.wrap(function() yieldtree(dir) end)
end

 Any help would be gratefully appreciated.

 Thanks,
 Mingranina

Add the files to a table, then use table.sort().
