Getting Help

QuickStart

pip3 install -U alex-ber-utils

Installing from Github

python3 -m pip install -U https://github.com/alex-ber/AlexBerUtils/archive/master.zip

Optionally installing tests requirements.

python3 -m pip install -U https://github.com/alex-ber/AlexBerUtils/archive/master.zip#egg=alex-ber-utils[tests]

Or explicitly:

wget https://github.com/alex-ber/AlexBerUtils/archive/master.zip -O master.zip; unzip master.zip; rm master.zip

And then installing from source (see below).

Installing from source

python3 -m pip install . # only installs "required"
python3 -m pip install .[tests] # installs dependencies for tests
python3 -m pip install .[md]   # installs multidispatcher (used in method_overloading_test.py)

From the directory with setup.py

python3 setup.py test #run all tests
pytest

Installing new version See https://docs.python.org/3.1/distutils/uploading.html

python3 setup.py sdist upload

Requirements

AlexBerUtils requires the following modules.

  • Python 3.7+

  • PyYAML==5.1

[Unrelased]

[0.4.1] - 2020-04-02

Changed

BREAKING CHANGE I highly recommend not to use 0.3.X versions.

  • Limitation::

mains module wasn't tested with frozen python script (frozen using py2exe).

  • module warns is droped
  • module mains is rewritten. Function initConf is dropped entirely.
  • module mains now works with logger and with warnings (it was wrong decision to work with warinings).

[0.3.4] - 2020-04-02

Changed

  • CHANGELOG.md fixed
  • warns module bug fixed, now warnings.warn() works.
  • FixabscwdWarning is added to simplify warnings disabling.
  • Changing how mains module use warns.

[0.3.3] - 2020-04-02

Changed

[0.3.2] - 2020-04-01

Changed

  • To REAMDE.md add Installing new version section
  • Fix typo in REAMDE.md (tests, not test).
  • Fixing bug: now, you're able to import package in the Python interpreter (setups.py fixed)
  • Fixing bug: warns module now doesn't change log_level in the preconfigured logger in any cases.
  • BREAKING CHANGE: Inmains module method warnsInitConfig() was renamed to mainInitConfig() Also singature was changed.
  • mains module minor refactored.

Added

  • Unit tests are added for warns module
  • Unit tests are added for mains module

[0.3.1] - 2020-04-01

Changed

  • Tests minor improvements.
  • Excluded tests, data from setup.py (from being installed from the sdist.)
  • Created MANIFEST.in

Added

  • warnsmodule is added:

It provides better integration between warnings and logger. Unlike logging._showwarning() this variant will always go through logger.

warns.initConfig() has optional file parameter (it's file-like object) to redirect warnings. Default value is sys.stderr.

If logger for log_name (default is py.warnings) will be configured before call to showwarning() method, than warning will go to the logger's handler with log_level (default is logging.WARNING).

If logger for log_name (default is py.warnings) willn't be configured before call to showwarning() method, than warning will be done to file (default is sys.stderr) with log_level (default is logging.WARNING).

  • main module is added:

main.fixabscwd() changes os.getcwd() to be the directory of the __main__ module.

main.warnsInitConfig() reexports warns.initConfig() for convenience.

Added

  • Tests for alexber.utils.thread_locals added.

[0.2.5] - 2019-05-22

Changed

  • Fixed bug in UploadCommand, git push should be before git tag.

[0.2.4] - 2019-05-22

Changed

  • Fixed bug in setup.py, incorrect order between VERSION and UploadCommand (no tag was created on upload)

[0.2.1] - 2019-05-22

Changed

  • setup url fixed.
  • Added import of Enum to alexber.utils package.

[0.2.0] - 2019-05-22

Changed

  • setup.py - keywords added.

[0.1.1] - 2019-05-22

Changed

  • README.md fixed typo.

[0.1.0] - 2019-05-22

Changed

  • alexber.utils.UploadCommand - bug fixed, failed on git tag, because VERSION was undefined.

[0.0.1] - 2019-05-22

Added

  • alexber.utils.StrAsReprMixinEnum - Enum Mixin that has str() equal to repr().

  • alexber.utils.AutoNameMixinEnum- Enum Mixin that generate value equal to the name.

  • alexber.utils.MissingNoneMixinEnum - Enum Mixin will return None if value will not be found.

  • alexber.utils.LookUpMixinEnum - Enim Mixin that is designed to be used for lookup by value.

    If lookup fail, None will be return. Also, str() will return the same value as repr().

  • alexber.utils.threadlocal_var, get_threadlocal_var, del_threadlocal_var.

    Inspired by https://stackoverflow.com/questions/1408171/thread-local-storage-in-python

  • alexber.utils.UploadCommand - Support setup.py upload.

    UploadCommand is intented to be used only from setup.py

    It's builds Source and Wheel distribution.

    It's uploads the package to PyPI via Twine.

    It's pushes the git tags.

  • alexber.utils.uuid1mc is is a hybrid between version 1 & version 4. This is v1 with random MAC ("v1mc").

    uuid1mc() is deliberately generating v1 UUIDs with a random broadcast MAC address.

    The resulting v1 UUID is time dependant (like regular v1), but lacks all host-specific information (like v4).

    Note: somebody reported that ran into trouble using UUID1 in Amazon EC2 instances.

  • alexber.utils.importer.importer - Convert str to Python construct that target is represented.

  • alexber.utils.importer.new_instance - Convert str to Python construct that target is represented. args and kwargs will be passed in to appropriate new() / init() / init_subclass() methods.

  • alexber.utils.inspects.issetdescriptor - Return true if the object is a method descriptor with setters.

    But not if ismethod() or isclass() or isfunction() are true.

  • alexber.utils.inspects.ismethod - Return false if object is not a class and not a function. Otherwise, return true iff signature has 2 params.

  • alexber.utils.parsers.safe_eval - The purpose of this function is convert numbers from str to correct type.

    This function support convertion of built-in Python number to correct type (int, float)

    This function doesn't support decimal.Decimal or datetime.datetime or numpy types.

  • alexber.utils.parsers.is_empty - if value is None returns True.

    if value is empty iterable (for example, empty str or emptry list),returns true otherwise false.

    Note: For not iterable values, behaivour is undefined.

  • alexber.utils.parsers.parse_boolean - if value is None returns None.

    if value is boolean, it is returned as it is. if value is str and value is equals ignoring case to "True", True is returned. if value is str and value is equals ignoring case to "False", False is returned.

    For every other value, the answer is undefined.

  • alexber.utils.props.Properties - A Python replacement for java.util.Properties class

    This is modelled as closely as possible to the Java original.

    Created - Anand B Pillai abpillai@gmail.com.

    Update to Python 3 by Alex.

    Also there are some tweeks that was done by Alex.
