21.2.0 (2021-10-12) ------------------- Backward-incompatible changes: - To implement pretty exceptions (see Changes below), ``structlog.dev.ConsoleRenderer`` now formats exceptions itself. Make sure to remove ``format_exc_info`` from your processor chain if you configure ``structlog`` manually. This change is not really breaking, because the old use-case will keep working as before. However if you pass ``pretty_exceptions=True`` (which is the default if either ``rich`` or ``better-exceptions`` is installed), a warning will be raised and the exception will be renderered without prettyfication. Changes: - ``structlog`` is now importable if ``sys.stdout`` is ``None`` (e.g. when running using ``pythonw``). - ``structlog.threadlocal.get_threadlocal()`` and ``structlog.contextvars.get_contextvars()`` can now be used to get a copy of the current thread-local/context-local context that has been bound using ``structlog.threadlocal.bind_threadlocal()`` and ``structlog.contextvars.bind_contextvars()``. - ``structlog.threadlocal.get_merged_threadlocal(bl)`` and ``structlog.contextvars.get_merged_contextvars(bl)`` do the same, but also merge the context from a bound logger *bl*. Same pull requests as previous change. - ``structlog.contextvars.bind_contextvars()`` now returns a mapping of keys to ``contextvars.Token``\s, allowing you to reset values using the new ``structlog.contextvars.reset_contextvars()``. - Exception rendering in ``structlog.dev.ConsoleLogger`` is now configurable using the ``exception_formatter`` setting. If either the `rich <https://github.com/willmcgugan/rich>`_ or the `better-exceptions <https://github.com/qix-/better-exceptions>`_ package is present, ``structlog`` will use them for pretty-printing tracebacks. ``rich`` takes precedence over ``better-exceptions`` if both are present. This only works if ``format_exc_info`` is **absent** in the processor chain. - All use of ``colorama`` on non-Windows systems has been excised. Thus, colors are now enabled by default in ``structlog.dev.ConsoleRenderer`` on non-Windows systems. You can keep using ``colorama`` to customize colors, of course. - The final processor can now return a ``bytearray`` (additionally to ``str`` and ``bytes``). |
