  class Logger:
      """An object to dispatch logging messages to configured handlers.
  
      The |Logger| is the core object of `loguru`, every logging configuration and usage pass through
      a call to one of its methods. There is only one logger, so there is no need to retrieve one
      before usage.
  
      Once the ``logger`` is imported, it can be used to write messages about events happening in your
      code. By reading the output logs of your application, you gain a better understanding of the
      flow of your program and you more easily track and debug unexpected behaviors.
  
      Handlers to which the logger sends log messages are added using the |add| method. Note that you
      can use the |Logger| right after import as it comes pre-configured (logs are emitted to
      |sys.stderr| by default). Messages can be logged with different severity levels and using braces
      attributes like the |str.format| method do.
  
      When a message is logged, a "record" is associated with it. This record is a dict which contains
      information about the logging context: time, function, file, line, thread, level... It also
      contains the ``__name__`` of the module, this is why you don't need named loggers.
  
      You should not instantiate a |Logger| by yourself, use ``from loguru import logger`` instead.

          Parameters
          ----------
          sink : |file-like object|_, |str|, |Path|, |function|_, |Handler| or |class|_
              An object in charge of receiving formatted logging messages and propagating them to an
              appropriate endpoint.
          level : |int| or |str|, optional
              The minimum severity level from which logged messages should be sent to the sink.
          format : |str| or |function|_, optional
              The template used to format logged messages before being sent to the sink.
          filter : |function|_ or |str|, optional
              A directive optionally used to decide for each logged message whether it should be sent
              to the sink or not.
          colorize : |bool|, optional
              Whether the color markups contained in the formatted message should be converted to ansi
              codes for terminal coloration, or stripped otherwise. If ``None``, the choice is
              automatically made based on the sink being a tty or not.
          serialize : |bool|, optional
              Whether the logged message and its records should be first converted to a JSON string
              before being sent to the sink.
          backtrace : |bool|, optional
              Whether the exception trace formatted should be extended upward, beyond the catching
              point, to show the full stacktrace which generated the error.
          diagnose : |bool|, optional
              Whether the exception trace should display the variables values to eases the debugging.
              This should be set to ``False`` in production to avoid leaking sensitive data.
          enqueue : |bool|, optional
              Whether the messages to be logged should first pass through a multiprocess-safe queue
              before reaching the sink. This is useful while logging to a file through multiple
              processes.
          catch : |bool|, optional
              Whether errors occurring while sink handles logs messages should be automatically
              caught. If ``True``, an exception message is displayed on |sys.stderr| but the exception
              is not propagated to the caller, preventing your app to crash.
          **kwargs
              Additional parameters that will be passed to the sink while creating it or while
              logging messages (the exact behavior depends on the sink type).
  
  
          If and only if the sink is a file, the following parameters apply:
  
          Parameters
          ----------
          rotation : |str|, |int|, |time|, |timedelta| or |function|_, optional
              A condition indicating whenever the current logged file should be closed and a new one
              started.
          retention : |str|, |int|, |timedelta| or |function|_, optional
              A directive filtering old files that should be removed during rotation or end of
              program.
          compression : |str| or |function|_, optional
              A compression or archive format to which log files should be converted at closure.
          delay : |bool|, optional
              Whether the file should be created as soon as the sink is configured, or delayed until
              first logged message. It defaults to ``False``.
          mode : |str|, optional
              The opening mode as for built-in |open| function. It defaults to ``"a"`` (open the
              file in appending mode).
          buffering : |int|, optional
              The buffering policy as for built-in |open| function. It defaults to ``1`` (line
              buffered file).
          encoding : |str|, optional
              The file encoding as for built-in |open| function. If ``None``, it defaults to
              |locale.getpreferredencoding|.
          **kwargs
              Others parameters are passed to the built-in |open| function.
  
          Returns
          -------
          :class:`int`
              An identifier associated with the added sink and which should be used to
              |remove| it.
  
          Notes
          -----
          Extended summary follows.
  
          .. _sink:
  
          .. rubric:: The sink parameter
  
          The ``sink`` handles incoming log messages and proceed to their writing somewhere and
          somehow. A sink can take many forms:
  
          - A |file-like object|_ like ``sys.stderr`` or ``open("somefile.log", "w")``. Anything with
            a ``.write()`` method is considered as a file-like object. If it has a ``.flush()``
            method, it will be automatically called after each logged message. If it has a ``.stop()``
            method, it will be automatically called at sink termination.
          - A file path as |str| or |Path|. It can be parametrized with some additional parameters,
            see below.
          - A simple |function|_ like ``lambda msg: print(msg)``. This allows for logging
            procedure entirely defined by user preferences and needs.
          - A built-in |Handler| like ``logging.StreamHandler``. In such a case, the `Loguru` records
            are automatically converted to the structure expected by the |logging| module.
          - A |class|_ object that will be used to instantiate the sink using ``**kwargs`` attributes
            passed. Hence, the class should instantiate objects which are therefore valid sinks.
  
          Note that you should avoid using  the ``logger`` inside any of your sinks as this would
          result in infinite recursion or dead lock if the module's sink was not explicitly disabled.
  
          .. _message:
  
          .. rubric:: The logged message
  
          The logged message passed to all added sinks is nothing more than a string of the
          formatted log, to which a special attribute is associated: the ``.record`` which is a dict
          containing all contextual information possibly needed (see below).
  
          Logged messages are formatted according to the ``format`` of the added sink. This format
          is usually a string containing braces fields to display attributes from the record dict.
  
          If fine-grained control is needed, the ``format`` can also be a function which takes the
          record as parameter and return the format template string. However, note that in such a
          case, you should take care of appending the line ending and exception field to the returned
          format, while ``"\n{exception}"`` is automatically appended for convenience if ``format`` is
          a string.
  
          The ``filter`` attribute can be used to control which messages are effectively passed to the
          sink and which one are ignored. A function can be used, accepting the record as an
          argument, and returning ``True`` if the message should be logged, ``False`` otherwise. If
          a string is used, only the records with the same ``name`` and its children will be allowed.
  
          .. _levels:
  
          .. rubric:: The severity levels
  
          Each logged message is associated with a severity level. These levels make it possible to
          prioritize messages and to choose the verbosity of the logs according to usages. For
          example, it allows to display some debugging information to a developer, while hiding it to
          the end user running the application.
  
          The ``level`` attribute of every added sink controls the minimum threshold from which log
          messages are allowed to be emitted. While using the ``logger``, you are in charge of
          configuring the appropriate granularity of your logs. It is possible to add even more custom
          levels by using the |level| method.
  
          Here are the standard levels with their default severity value, each one is associated with
          a logging method of the same name:
  
          +----------------------+------------------------+------------------------+
          | Level name           | Severity value         | Logger method          |
          +======================+========================+========================+
          | ``TRACE``            | 5                      | |logger.trace|         |
          +----------------------+------------------------+------------------------+
          | ``DEBUG``            | 10                     | |logger.debug|         |
          +----------------------+------------------------+------------------------+
          | ``INFO``             | 20                     | |logger.info|          |
          +----------------------+------------------------+------------------------+
          | ``SUCCESS``          | 25                     | |logger.success|       |
          +----------------------+------------------------+------------------------+
          | ``WARNING``          | 30                     | |logger.warning|       |
          +----------------------+------------------------+------------------------+
          | ``ERROR``            | 40                     | |logger.error|         |
          +----------------------+------------------------+------------------------+
          | ``CRITICAL``         | 50                     | |logger.critical|      |
          +----------------------+------------------------+------------------------+
  
          .. _record:
  
          .. rubric:: The record dict
  
          The record is just a Python dict, accessible from sinks by ``message.record``. It contains
          all contextual information of the logging call (time, function, file, line, level, etc.).
  
          Each of its key can be used in the handler's ``format`` so the corresponding value is
          properly displayed in the logged message (e.g. ``"{level}"`` -> ``"INFO"``). Some record's
          values are objects with two or more attributes, these can be formatted with ``"{key.attr}"``
          (``"{key}"`` would display one by default). `Formatting directives`_ like ``"{key: >3}"``
          also works and is particularly useful for time (see below).
  
          +------------+---------------------------------+----------------------------+
          | Key        | Description                     | Attributes                 |
          +============+=================================+============================+

          +------------+---------------------------------+----------------------------+
          | exception  | The formatted exception if any, | ``type``, ``value``,       |
          |            | ``None`` otherwise              | ``traceback``              |

          .. rubric:: The time formatting
  
          To use your favorite time representation, you can set it directly in the time formatter
          specifier of your handler format, like for example ``format="{time:HH:mm:ss} {message}"``.
          Note that this datetime represents your local time, and it is also made timezone-aware,
          so you can display the UTC offset to avoid ambiguities.
  
          The time field can be formatted using more human-friendly tokens. These constitute a subset
          of the one used by the `Pendulum`_ library of `@sdispater`_. To escape a token, just add
          square brackets around it, for example ``"[YY]"`` would display literally ``"YY"``.
  
          If no time formatter specifier is used, like for example if ``format="{time} {message}"``,
          the default one will use ISO 8601.

          .. _file:
  
          .. rubric:: The file sinks
  
          If the sink is a |str| or a |Path|, the corresponding file will be opened for writing logs.
          The path can also contain a special ``"{time}"`` field that will be formatted with the
          current date at file creation.
  
          The ``rotation`` check is made before logging each message. If there is already an existing
          file with the same name that the file to be created, then the existing file is renamed by
          appending the date to its basename to prevent file overwriting. This parameter accepts:
  
          - an |int| which corresponds to the maximum file size in bytes before that the current
            logged file is closed and a new one started over.
          - a |timedelta| which indicates the frequency of each new rotation.
          - a |time| which specifies the hour when the daily rotation should occur.
          - a |str| for human-friendly parametrization of one of the previously enumerated types.
            Examples: ``"100 MB"``, ``"0.5 GB"``, ``"1 month 2 weeks"``, ``"4 days"``, ``"10h"``,
            ``"monthly"``, ``"18:00"``, ``"sunday"``, ``"w0"``, ``"monday at 12:00"``, ...
          - a |function|_ which will be called before logging. It should accept two
            arguments: the logged message and the file object, and it should return ``True`` if
            the rotation should happen now, ``False`` otherwise.
  
          The ``retention`` occurs at rotation or at sink stop if rotation is ``None``. Files are
          selected according to their basename, if it is the same that the sink file, with possible
          time field being replaced with ``.*``. This parameter accepts:
  
          - an |int| which indicates the number of log files to keep, while older files are removed.
          - a |timedelta| which specifies the maximum age of files to keep.
          - a |str| for human-friendly parametrization of the maximum age of files to keep.
            Examples: ``"1 week, 3 days"``, ``"2 months"``, ...
          - a |function|_ which will be called before the retention process. It should accept the list
            of log files as argument and process to whatever it wants (moving files, removing them,
            etc.).
  
          The ``compression`` happens at rotation or at sink stop if rotation is ``None``. This
          parameter accepts:
  
          - a |str| which corresponds to the compressed or archived file extension. This can be one
            of: ``"gz"``, ``"bz2"``, ``"xz"``, ``"lzma"``, ``"tar"``, ``"tar.gz"``, ``"tar.bz2"``,
            ``"tar.xz"``, ``"zip"``.
          - a |function|_ which will be called before file termination. It should accept the path
            of the log file as argument and process to whatever it wants (custom compression,
            network sending, removing it, etc.).
  
          .. _color:
  
          .. rubric:: The color markups
  
          To add colors to your logs, you just have to enclose your format string with the appropriate
          tags (e.g. ``<tag>some message</tag>``). These tags are automatically removed if the sink
          doesn't support ansi codes. For convenience, you can use ``</>`` to close the last opening
          tag without repeating its name (e.g. ``<tag>another message</>``).
  
          The special tag ``<level>`` (abbreviated with ``<lvl>``) is transformed according to
          the configured color of the logged message level.
  
          Tags which are not recognized will raise an exception during parsing, to inform you about
          possible misuse. If you wish to display a markup tag literally, you can escape it by
          prepending a ``\`` like for example ``\<blue>``. If, for some reason, you need to escape a
          string programmatically, note that the regex used internally to parse markup tags is
          ``r"\\?</?((?:[fb]g\s)?[^<>\s]*)>"``.
  
          Here are the available tags (note that compatibility may vary depending on terminal):

          environment variable. For example on Linux: ``export LOGURU_FORMAT="{time} - {message}"``
          or ``export LOGURU_DIAGNOSE=NO``.
  
          The default levels' attributes can also be modified by setting the ``LOGURU_[LEVEL]_[ATTR]``
          environment variable. For example, on Windows: ``setx LOGURU_DEBUG_COLOR "<blue>"``
          or ``setx LOGURU_TRACE_ICON "🚀"``.
  
          If you want to disable the pre-configured sink, you can set the ``LOGURU_AUTOINIT``
          variable to ``False``.
  
          On Linux, you will probably need to edit the ``~/.profile`` file to make this persistent. On
          Windows, don't forget to restart your terminal for the change to be taken into account.

          This is useful to ensure unexpected exceptions are logged, the entire program can be

          Note that the visibility of variables values (which uses the cool `better_exceptions`_
          library from `@Qix-`_) depends on the ``diagnose`` option of each configured sink.

          ----------
          exception : |Exception|, optional
              The type of exception to intercept. If several types should be caught, a tuple of
              exceptions can be used too.
          level : |str| or |int|, optional
              The level name or severity with which the message should be logged.
          reraise : |bool|, optional
              Whether the exception should be raised again and hence propagated to the caller.
          message : |str|, optional
              The message that will be automatically logged if an exception occurs. Note that it will
              be formatted with the ``record`` attribute.

          -------
          decorator / context manager
              An object that can be used to decorate a function or as a context manager to log
              exceptions possibly caught.

          Parameters
          ----------
          exception : |bool|, |tuple| or |Exception|, optional
              If it does not evaluate as ``False``, the passed exception is formatted and added to the
              log message. It could be an |Exception| object or a ``(type, value, traceback)`` tuple,
              otherwise the exception information is retrieved from |sys.exc_info|.
          record : |bool|, optional
              If ``True``, the record dict contextualizing the logging call can be used to format the
              message by using ``{record[key]}`` in the log message.
          lazy : |bool|, optional
              If ``True``, the logging call attribute to format the message should be functions which
              will be called only if the level is high enough. This can be used to avoid expensive
              functions if not necessary.
          ansi : |bool|, optional
              If ``True``, logged message will be colorized according to the markups it possibly
              contains.
          raw : |bool|, optional
              If ``True``, the formatting of each sink will be bypassed and the message will be sent
              as is.
          depth : |int|, optional
              Specify which stacktrace should be used to contextualize the logged message. This is
              useful while using the logger from inside a wrapped function to retrieve worthwhile
              information.

              The function is executed prior to the one possibly added by the |patch| method. If not

      def parse(file, pattern, *, cast={}, chunk=2 ** 16):
          """
          Parse raw logs and extract each entry as a |dict|.
  
          The logging format has to be specified as the regex ``pattern``, it will then be
          used to parse the ``file`` and retrieve each entry based on the named groups present
          in the regex.
  
          Parameters
          ----------
          file : |str|, |Path| or |file-like object|_
              The path of the log file to be parsed, or an already opened file object.
          pattern : |str| or |re.Pattern|_
              The regex to use for logs parsing, it should contain named groups which will be included
              in the returned dict.
          cast : |function|_ or |dict|, optional
              A function that should convert in-place the regex groups parsed (a dict of string
              values) to more appropriate types. If a dict is passed, it should be a mapping between
              keys of parsed log dict and the function that should be used to convert the associated
              value.
          chunk : |int|, optional
              The number of bytes read while iterating through the logs, this avoids having to load
              the whole file in memory.
  
          Yields
          ------
          :class:`dict`
              The dict mapping regex named groups to matched values, as returned by |match.groupdict|
              and optionally converted according to ``cast`` argument.
  
          Examples
          --------
          >>> reg = r"(?P<lvl>[0-9]+): (?P<msg>.*)"    # If log format is "{level.no} - {message}"
          >>> for e in logger.parse("file.log", reg):  # A file line could be "10 - A debug message"
