I tried this. With this code, I can't make it fail, even without the
sleep. I assume this is because spawn is itself introducing a delay. I'm
not holding this code up as a shining example of what to do. It's a
dirty hack from beginning to end. = function()
   -- paste.bat adds an extra unwanted newline
   local paste_should_be = buffer.get_sel_text() .. "\n"
   local paste_output = ''
   local function paste_stdout(chunk)
     paste_output = paste_output .. chunk
   local function tohex(s)
     return (s:gsub('.', function (c)
         return string.format('%02X', string.byte(c))
   local function removecr(s)
     return (s:gsub("\x0d\x0a", function (c)
         return "\n"
   local function paste_exit(rc)
     local testval = removecr(paste_output)
     if testval ~= paste_should_be then
       -- converted to hex so I can see differences in whitespace
       ui.print("BAD clipboard: '" .. tohex(testval) .. "'")
       ui.print("BAD selection: '" .. tohex(paste_should_be) .. "'")
       ui.dialogs.msgbox({text="Clipboard problem ..."})
   if WIN32 then
     local p = spawn("D:\\paste.bat", nil, paste_stdout, nil, paste_exit)

But I think I'm going back to a simple sleep. I'll know soon enough if
it doesn't work.

Thanks for your help.
