C++ How do I show datetime to my console outputs

[Paulix]

Title, my console is like this on TFS 1.4

I want to add date time to something like 0.4

C++ Date and Time

C++ Date and Time - The C++ standard library does not provide a proper date type. C++ inherits the structs and functions for date and time manipulation from C. To access date and time related functions and structures, you would need to include header file in your C++ program.

on all "couts" and similar funcs (.cpp files)

I was looking on 0.4 sources, and looks like thats not how it is done (can't find how it is), it must have a better way to do this

it might be have done differently because that was the GUI version, not console one

Overriding cout like this:

Add prefixes to ostream outputs

I am looking for a way of adding a prefix to an ostream, pass it down to other functions so that their outputs are prefixed and then remove it to continue. Check the following pseudocode: ... v...

stackoverflow.com

or this (unlikely to work?):
C++ output with prefix padding (https://stackoverflow.com/questions/11916698/c-output-with-prefix-padding)

or replacing every output with your own functions like this and adding a prefix in a single place (not finished yet):

(WIP) updated startup logic + color · Zbizu/forgottenserver@ec2cf00

to do: replace remaining std::couts to dedicated error function

github.com

(check later commits for a more elegant solution for common warnings/errors)

You can also search "cout" in 0.4 sources to see if/where/how was it overridden or load the files in visual studio and go to sendMessage definition

Overall, if you need the date/time prefix in logs, consider adding it to your console logging script rather than making heavy source edits (or just wait until I finish)

On linux you can use ts for this, it's in moreutils package:

sudo apt install moreutils

Example run:

./tfs 2>&1 | ts '[%Y-%m-%d %H:%M:%.S]'

Auto-restarter:

#!/bin/bash

ulimit -c unlimited

while true; do
 echo SERVER START
 ./tfs 2>&1 | ts '[%Y-%m-%d %H:%M:%.S]'
 echo RESTART, CTRL+C TO CLOSE RESTARTER
 sleep 3

done

How it looks in console:
