thinlog.formatters.json module#

JSON formatter with rich exception context via structlog.

class thinlog.formatters.json.JsonFormatter(show_locals: bool = False, **kwargs: Any)[source]#

Bases: Formatter

Serialize the full log record as a JSON string.

Exception tracebacks are converted to structured dicts using structlog.tracebacks.ExceptionDictTransformer, and stack-info frames are extracted via parse_stack_info().

Parameters:

show_locals – If True, local variables are included in exception tracebacks.

format(record: LogRecord) → str[source]#

Return the record as a JSON string.

formatException(ei: tuple[type[BaseException], BaseException, TracebackType | None] | tuple[None, None, None]) → str[source]#

Format exception info as a JSON string, falling back to the standard formatter.

classmethod format_exception(ei: tuple[type[BaseException], BaseException, TracebackType | None] | tuple[None, None, None]) → Any[source]#

Transform exception info into a structured dict via structlog.

classmethod format_record(record: LogRecord) → dict[str, Any][source]#

Convert a LogRecord to a plain dict.

Handles exc_info (via structlog transformer) and stack_info (via parse_stack_info()).

transformer: ClassVar[ExceptionDictTransformer]#
