Allow to configure the behaviour of StandardRenderer

[kretes]

Currently we use StandardRenderer with no_update=True and it is used in a process that uses tqdm (keras training loop).
The effect is that the first line from ticktock is appended at the end of the line of current tqdm progress.
I can see in https://github.com/victorbenichoux/ticktock/blob/main/ticktock/std.py#L137 there is a new line appended at the end of ticktock output. We would like to add a new line at the beginning as well. WDYT of either including it be default or allowing to customize it by the client?

Hi @kretes !

Thanks for the feedback. As you can see, I have been struggling quite a bit with the tqdm integration, and I have not quite been able to make it work with updates 😬 .

I am not able to reproduce the behavior you are describing, although I may be doing something wrong. I am testing with the following code:

import time
import tqdm
from ticktock import set_format, set_period, tick

set_period(0)
set_format(no_update=True)

which = "in"

for _ in range(2):
    t_out = tick(enabled=which == "out")
    for aa in tqdm.tqdm(range(2)):
        t_in = tick(which == "in")
        time.sleep(0.1)
        t_in.tock()
    t_out.tock()

I am switching between which="in" and which="out" and in both cases, the ticktock lines seem to be correctly generated. In addition, adding a new line at the beginning of each block introduces blank lines. So I figure I must be doing something wrong.

Could you give me more information to reproduce the issue? I am really happy to take any suggestion, and if it turns out that adding a newline fixes it for you, I will add in a way to allow the user to do so 😄 . If you can not provide a simple example, I guess we're on the same time zone so we can probably work something out!

In any event, I do do need to go back and fix the behavior with tqdm. If you want to help out feel free!
