目标: Configure RichHandler with Python stdlib logging safely without double level or timestamp columns, markup crashes on untrusted bracketed strings, or missing traceback frame locals HOW
包: rich 15.0.0
环境: python
创建时间: 2026-08-16T06:22:48Z

assert RichHandler defaults to markup=False unlike Console(markup=True), preserving literal tags unless extra={'markup': True} or handler markup=True
assert RichHandler(markup=True) raises rich.errors.MarkupError on unescaped closing tags like [/status] in logged strings, which escape() or extra={'markup': False} prevents
assert Formatter format strings with %(asctime)s or %(levelname)s cause duplicated level badges and timestamps inside message columns, while %(message)s keeps columns clean
assert Formatter.datefmt overrides RichHandler.log_time_format when attached, while log_time_format acts as fallback when formatter is None
assert omit_repeated_times=True blanks timestamps for consecutive records within the same second, while omit_repeated_times=False prints timestamps on every record
assert ReprHighlighter and keyword highlighting style numbers and HTTP verbs by default, and suppressing highlighting requires highlighter=NullHighlighter() and keywords=[]
assert rich_tracebacks defaults to False emitting plain string tracebacks, while rich_tracebacks=True renders formatted Traceback boxes with tracebacks_show_locals inspecting frame variables
assert show_time=False, show_level=False, show_path=False strip Rich's structural columns while LogRender expands message to console width
assert RichHandler initializes seamlessly in logging.config.dictConfig with custom formatters and rich_tracebacks
