Usage

Put this code in your template. The message will only show in Show preview (you can try with this page):

  • {{#invoke:Preview warning|main|Message text}}



local p = {}

function p.main(frame)
	local preview = frame.args[1]:match('^%s*(.-)%s*$') or ''
	if preview == '' then preview = 'Something is wrong with this template' end
	if frame:preprocess( "{{REVISIONID}}" ) == "" then return '<div class="hatnote" style="color:red"><strong>Warning:</strong> ' .. preview .. ' (this message is shown only in preview).</div>' end
end

return p
