Dear list,

I have the following sample:

  \starttext
  \startluacode
  main_file = document.files[1]

  if file.pathpart(main_file) == "" then
    main_filename = file.nameonly(main_file)
    main_filename_win = main_filename
  else
    main_filename = file.pathpart(main_file):gsub(io.fileseparator, "/")
       .. "/" .. file.nameonly(main_file)
    docx_file = main_filename .. "-file.docx"
    epub_file = main_filename .. "-file.epub"
    if os.name == "windows" then
      main_filename_win = file.pathpart(main_file) .. io.fileseparator
        .. file.nameonly(main_file)
      docx_file_win = main_filename_win .. "-file.docx"
      epub_file_win = main_filename_win .. "-file.epub"
    end
  end

  if os.name=="windows" then
    context(docx_file_win)
    os.execute("copy " .. docx_file_win .. " aeae")
  else
    context(docx_file)
  end
  \stopluacode
  \stoptext

If I run it on Windows, context(docx_file_win) cannot deal with the
backslash, so I get:

  .document-file.docx

So it is impossible that os.execute may work with copy.

Running it with Linux, I get "./document-file.docx".

How can I get the io.fileseparator or escape the backslash in
main_filename_win above?

Many thanks for your help,

Pablo
