Hi

When debugging, sometimes i want to know which file and line is the pprint / print log come from.

Is there anyway to know it from the log?

Thank you

          	local level_string = M.log_level_names[level]
          	
          	local path = M.get_logging_path()
          	local log = io.open(path, "a")
          	local timestamp = os.time()
          	local timestamp_string = os.date('%Y-%m-%d %H:%M:%S', timestamp)
          
          	local head = "[" .. level_string .. timestamp_string .. "]"
          	local body = ""
          	
          	if debug then
          		local info = debug.getinfo(2 + debug_level, "Sl") -- https://www.lua.org/pil/23.1.html
          		local short_src = info.short_src
          		local line_number = info.currentline		
          		body = short_src .. ":" .. line_number .. ":"
          	end
          
          	local complete_line = head .. " " .. body .. " " .. line
          	if M.print == true then print(complete_line) end
          	
          	log:write(complete_line, "\n")

You can make your function for print, or replace global print function
