Loguru v0.4.1 Release Notes

Release Date: 2020-01-19 // about 1 month ago
    • 🗄 Deprecate the ansi parameter of .opt() in favor of colors which is a name more appropriate.
    • Prevent unrelated files and directories to be incorrectly collected thus causing errors during the retention process (#195 <https://github.com/Delgan/loguru/issues/195>, thanks @gazpachoking <https://github.com/gazpachoking>).
    • 🌲 Strip color markups contained in record["message"] when logging with .opt(ansi=True) instead of leaving them as is (#198 <https://github.com/Delgan/loguru/issues/198>_).
    • Ignore color markups contained in *args and **kwargs when logging with .opt(ansi=True), leave them as is instead of trying to use them to colorize the message which could cause undesirable errors (#197 <https://github.com/Delgan/loguru/issues/197>_).

Previous changes from v0.4.0

    • ➕ Add support for coroutine functions used as sinks and add the new logger.complete() asynchronous method to await them (#171 <https://github.com/Delgan/loguru/issues/171>_).
    • ➕ Add a way to filter logs using one level per module in the form of a dict passed to the filter argument (#148 <https://github.com/Delgan/loguru/issues/148>_).
    • ➕ Add type hints to annotate the public methods using a .pyi stub file (#162 <https://github.com/Delgan/loguru/issues/162>_).
    • ➕ Add support for copy.deepcopy() of the logger allowing multiple independent loggers with separate set of handlers (#72 <https://github.com/Delgan/loguru/issues/72>_).
    • ➕ Add the possibility to convert datetime to UTC before formatting (in logs and filenames) by adding "!UTC" at the end of the time format specifier (#128 <https://github.com/Delgan/loguru/issues/128>_).
    • ➕ Add the level name as the first argument of namedtuple returned by the .level() method.
    • ✂ Remove class objects from the list of supported sinks and restrict usage of **kwargs in .add() to file sink only. User is in charge of instantiating sink and wrapping additional keyword arguments if needed, before passing it to the .add() method.
    • 🔧 Rename the logger.configure() keyword argument patch to patcher so it better matches the signature of logger.patch().
    • 🛠 Fix incompatibility with multiprocessing on Windows by entirely refactoring the internal structure of the logger so it can be inherited by child processes along with added handlers (#108 <https://github.com/Delgan/loguru/issues/108>_).
    • Fix AttributeError while using a file sink on some distributions (like Alpine Linux) missing the os.getxattr and os.setxattr functions (#158 <https://github.com/Delgan/loguru/pull/158>, thanks @joshgordon <https://github.com/joshgordon>).
    • 🛠 Fix values wrongly displayed for keyword arguments during exception formatting with diagnose=True (#144 <https://github.com/Delgan/loguru/issues/144>_).
    • 🛠 Fix logging messages wrongly chopped off at the end while using standard logging.Handler sinks with .opt(raw=True) (#136 <https://github.com/Delgan/loguru/issues/136>_).
    • 🛠 Fix potential errors during rotation if destination file exists due to large resolution clock on Windows (#179 <https://github.com/Delgan/loguru/issues/179>_).
    • 🛠 Fix an error using a filter function "by name" while receiving a log with record["name"] equals to None.
    • 🛠 Fix incorrect record displayed while handling errors (if catch=True) occurring because of non-picklable objects (if enqueue=True).
    • Prevent hypothetical ImportError if a Python installation is missing the built-in distutils module (#118 <https://github.com/Delgan/loguru/issues/118>_).
    • Raise TypeError instead of ValueError when a logger method is called with argument of invalid type.
    • Raise ValueError if the built-in format() and filter() functions are respectively used as format and filter arguments of the add() method. This helps the user to understand the problem, as such a mistake can quite easily occur (#177 <https://github.com/Delgan/loguru/issues/177>_).
    • ✂ Remove inheritance of some record dict attributes to str (for "level", "file", "thread" and "process").
    • Give a name to the worker thread used when enqueue=True (#174 <https://github.com/Delgan/loguru/pull/174>, thanks @t-mart <https://github.com/t-mart>).
