zope.hookable

This package supports the efficient creation of "hookable" objects, which are callable objects that are meant to be optionally replaced.

The idea is that you create a function that does some default thing and make it hookable. Later, someone can modify what it does by calling its sethook method and changing its implementation. All users of the function, including those that imported it, will see the change.

Changes

7.0 (2024-09-17)

• Drop support for Python 3.7.

• Add support for Python 3.13.

• Build windows wheels on GHA.

6.0 (2023-10-05)

• Drop support for Python 2.7, 3.5, 3.6.
• Add support for Python 3.12.

5.4 (2022-11-17)

• Add support for building arm64 wheels on macOS.

5.3 (2022-11-03)

• Add support for the final release of Python 3.11.

5.2 (2022-09-13)

• Add support for Python 3.10 and 3.11 (as of 3.11.0rc1).
• Disable unsafe math optimizations in C code. See pull request 25.

5.1.0 (2021-07-20)

• Add support for Python 3.9.
• Create Linux aarch64 wheels.

5.0.1 (2020-03-10)

• Stop using the setuptools Feature class, allowing this project to be built from source with newer versions of setuptools that remove that functionality.

5.0.0 (2019-11-12)

• Drop support for Python 3.4.

4.2.0 (2017-11-07)

• Expose the __doc__ (and, where applicable, __bases__ and __dict__) of the hooked object. This lets Sphinx document them. See issue 6.
• Respect PURE_PYTHON at runtime. At build time, always try to build the C extensions on supported platforms, but allow it to fail. See issue 7.

4.1.0 (2017-07-26)

• Update boostrap.py to version 2.2.
• Fix extension compilation on Py3k.

4.0.2 (2012-12-31)

• Flesh out PyPI Trove classifiers.

4.0.1 (2012-11-21)

• Add support for Python 3.3.
• Avoid building the C extension explicitly (use the "feature" indirection instead).

4.0.0 (2012-06-04)

• Add support for PyPy.
• Add support for continuous integration using tox and jenkins.
• Add a pure-Python reference implementation.
• Move doctests to Sphinx documentation.
• Bring unit test coverage to 100%.
• Add 'setup.py docs' alias (installs Sphinx and dependencies).
• Add 'setup.py dev' alias (runs setup.py develop plus installs nose and coverage).
• Drop support for Python 2.4 / 2.5.
• Remove of 'zope.testing.doctestunit' in favor of stdlib's 'doctest.
• Add Python 3 support.

3.4.1 (2009-04-05)
