Ability to re-print RichHandler log files with rich format? (python)

[KardoPaska]

Hello friends:

I like Rich a lot for live logging, but later, I do not like reading my log file in black and white.

I am wondering if there is a way to reprint existing log files that were written by a RichHandler (via python's logging.FileHandler)?

In other words, how to go both ways? Can write the log lines to a file and Rich print to console very nicely. But how can read from a file and also Rich print to console the log lines as they were originally?

Rich does well and prints this:

But when i look at the log file it looks like this:

And when i try to replay it, looks like this:

Here is my minimum reproducible example from excerpted code to illustrate the idea. Please forgive any omissions, i pluck it out of my production code right now.

import logging
from rich.logging import RichHandler
from rich.console import Console
from datetime import datetime
import time


## redo loggerings
root_logger = logging.getLogger(name=None) #root logger
for handler in root_logger.handlers[:]: #destroy fluff
    root_logger.removeHandler(handler)
    handler.close()


## setup new log handlers
fp_save = r"D:\pythong\my_rich_loggings.log"
my_filehandler = logging.FileHandler(fp_save)
my_fmt = "%(asctime)s [%(levelname)s] %(name)s:%(funcName)s:%(lineno)-8d %(message)s"
file_formatter = logging.Formatter(fmt=my_fmt)
my_filehandler.setFormatter(file_formatter)

handlers_here = [my_filehandler, ]

the_level = 'NOTSET'
logging.basicConfig(level=the_level,
                    handlers=handlers_here,
                    encoding='latin-1')


## add a rich
console = Console(soft_wrap=True, width=999)
my_rich_console_handler = RichHandler(show_time=True,
                                      show_level=True,
                                      console=console)
logger = logging.getLogger(name=__name__)
logger.addHandler(my_rich_console_handler)
logger.setLevel(the_level)


## DO IT
logger.info(f'hello 123 {datetime.now()}')
time.sleep(1)
logger.warning(f'world 456 {datetime.now()}')
time.sleep(1)
logger.error(f'to you 789 {datetime.now()}')



#%%  TRY TO REPRINTER



def rprint(*args, **kwargs):
    return console.print(*args, **kwargs, no_wrap=True, soft_wrap=True)


with open(r"D:\pythong\my_rich_loggings.log", 'r') as f:
    n_prints = 0
    while f:
        line = f.readline()
        if not line:
            break

        assert line[-1] == '\n', line
        line = line[:-1]

        rprint(line)
        n_prints += 1
        if n_prints > 999:
            break
