class RichHandler(Handler):
"""A logging handler that renders output with Rich. The time / level / message and file are displayed in columns.
The level is color coded, and the message is syntax highlighted.
Note:
Be careful when enabling console markup in log messages if you have configured logging for libraries not
under your control. If a dependency writes messages containing square brackets, it may not produce the intended output.
Args:
level (Union[int, str], optional): Log level. Defaults to logging.NOTSET.
console (:class:`~rich.console.Console`, optional): Optional console instance to write logs.
Default will use a global console instance writing to stdout.
show_time (bool, optional): Show a column for the time. Defaults to True.
omit_repeated_times (bool, optional): Omit repetition of the same time. Defaults to True.
show_level (bool, optional): Show a column for the level. Defaults to True.
show_path (bool, optional): Show the path to the original log call. Defaults to True.
enable_link_path (bool, optional): Enable terminal link of path column to file. Defaults to True.
highlighter (Highlighter, optional): Highlighter to style log messages, or None to use ReprHighlighter. Defaults to None.
markup (bool, optional): Enable console markup in log messages. Defaults to False.
rich_tracebacks (bool, optional): Enable rich tracebacks with syntax highlighting and formatting. Defaults to False.
tracebacks_width (Optional[int], optional): Number of characters used to render tracebacks, or None for full width. Defaults to None.
tracebacks_extra_lines (int, optional): Additional lines of code to render tracebacks, or None for full width. Defaults to None.
tracebacks_theme (str, optional): Override pygments theme used in traceback.
tracebacks_word_wrap (bool, optional): Enable word wrapping of long tracebacks lines. Defaults to True.
tracebacks_show_locals (bool, optional): Enable display of locals in tracebacks. Defaults to False.
tracebacks_suppress (Sequence[Union[str, ModuleType]]): Optional sequence of modules or paths to exclude from traceback.
locals_max_length (int, optional): Maximum length of containers before abbreviating, or None for no abbreviation.
Defaults to 10.
locals_max_string (int, optional): Maximum length of string before truncating, or None to disable. Defaults to 80.
log_time_format (Union[str, TimeFormatterCallable], optional): If ``log_time`` is enabled, either string for strftime or callable that formats the time. Defaults to "[%x %X] ".
keywords (List[str], optional): List of words to highlight instead of ``RichHandler.KEYWORDS``.
