Test compatibility with Python 3.13

Bug fixes:

Fix a few __all__ variables.
Added missing docs folder to distribution packages.

6.0.0a0 (2024-07-03)

Minor changes:
    Test that all code works with both pytz and zoneinfo.
    Add message to GitHub release, pointing to the changelog
    Make coverage report submission optional for pull requests
    Parallelize coverage
    Rename master branch to main, see Issue
    Update docs/usage.rst to use zoneinfo instead of pytz.
    Added missing public classes and functions to API documentation.
    Improved namespace management in the icalendar directory.
    Add Python version badge and badge for test coverage
    Remove 4.x badge
    Update list of tox environments
    Use Coveralls’ GitHub Action
    Check distribution in CI
Breaking changes:
    Use zoneinfo for icalendar objects created from strings, see Issue #609.
    This is an tested extension of the functionality, not a restriction: If you create icalendar objects with pytz timezones in your code, icalendar will continue to work in the same way. Your code is not affected.
    zoneinfo will be used for those objects that icalendar creates itself. This happens for example when parsing an .ics file, strings or bytes with from_ical().
    If you rely on icalendar providing timezones from pytz, you can add one line to your code to get the behavior of versions below 6:
    import icalendar
    icalendar.use_pytz()
Replaced pkg_resources.get_distribution with importlib.metadata in docs/conf.py to allow building docs on Python 3.12.
Remove is_broken property. Use errors instead to check if a component had suppressed parsing errors. See Issue 424.
Remove untested and broken LocalTimezone and FixedOffset tzinfo sub-classes, see Issue 67
Remove Python 3.7 as compatible. icalendar is compatible with Python versions 3.8 - 3.12, and PyPy3.
Remove pytz as a dependency of icalendar. If you require pytz, add it to your dependency list or install it additionally with:
pip install icalendar==6.* pytz
New features:
    Check code quality with Ruff, optional report
    Test compatibility with Python 3.12
    Add function icalendar.use_pytz().
    Allows selecting components with walk(select=func) where func takes a component and returns True or False.
    Add compatibility to RFC 7529, adding vMonth and vSkip
    Add sphinx-autobuild for livehtml Makefile target.
    Add pull request preview on Read the Docs, building only on changes to documentation-related files.
    Add link to pull request preview builds in the pull request description only when there are changes to documentation-related files.
    Add documentation of live HTML preview of documentation and clean up of install.rst.
    Add sphinx-copybutton to allow copying code blocks with a single click of a button.
Bug fixes:
    Change documentation to represent compatibility with Python 3.8 - 3.12, and PyPy3.
    Rename RFC 2445 to RFC 5545, see Issue 278

------------------

- Exclude editor backup files from egg distributions. Fixes #144.
  [thet]

Update to 3.8.1:

3.8.1 (2014-07-17)
------------------

- The representation of CaselessDicts in 3.8 changed the name attribute of
  Components and therefore broke the external API. This has been fixed.
  [untitaker]


3.8 (2014-07-17)
----------------

- Allow dots in property names (Needed for vCard compatibility). Refs #143.
  [untitaker]

- Change class representation for CaselessDict objects to always include the
  class name or the class' name attribute, if available. Also show
  subcomponents for Component objects.
  [thet]

- Don't use data_encode for CaselessDict class representation but use dict's
  __repr__ method.
  [t-8ch]

- Handle parameters with multiple values, which is needed for vCard 3.0.
  Refs #142.
  [t-8ch]

Update to 3.7:

3.7 (2014-06-02)
----------------

- For components with ``ignore_exceptions`` set to ``True``, mark unparseable
  lines as broken instead rising a ``ValueError``. ``VEVENT`` components have
  ``ignore_exceptions`` set to ``True`` by default. Ref #131. Fixes #104.
  [jkiang13]

- Make ``python-dateutil`` a soft-dependency.
  [boltnev]

- Add optional ``sorted`` parameter to ``Component.to_ical``. Setting it to
  false allows the user to preserve the original property and parameter order.
  Ref #136. Fixes #133.
  [untitaker]

- Fix tests for latest ``pytz``. Don't set ``tzinfo`` directly on datetime
  objects, but use pytz's ``localize`` function. Ref #138.
  [untitaker, thet]

- Remove incorrect use of __all__. We don't encourage using ``from package
  import *`` imports. Fixes #129.
  [eric-wieser]


3.6.2 (2014-04-05)
------------------

- Pep8 and cleanup.
  [lasudry]

Update to 3.6.1:

3.6.1 (2014-01-13)
------------------

- Open text files referenced by setup.py as utf-8, no matter what the locale
  settings are set to. Fixes #122.
  [sochotnicky]

- Add tox.ini to source tarball, which simplifies testing for in distributions.
  [sochotnicky]


3.6 (2014-01-06)
----------------

- Python3 (3.3+) + Python 2 (2.6+) support [geier]

- Made sure to_ical() always returns bytes [geier]

- Support adding lists to a component property, which value already was a list
  and remove the Component.set method, which was only used by the add method.
  [thet]

- Remove ability to add property parameters via a value's params attribute when
  adding via cal.add (that was only possible for custom value objects and makes
  up a strange API), but support a parameter attribute on cal.add's method
  signature to pass a dictionary with property parameter key/value pairs.
  Fixes #116.
  [thet]

- Backport some of Regebro's changes from his regebro-refactor branch.
  [thet]

- Raise explicit error on another malformed content line case.
  [hajdbo]

- Correctly parse datetime component property values with timezone information
  when parsed from ical strings.
  [untitaker]

Convert to use versioned_dependencies.mk.

3.5 (2013-07-03)
----------------

- Let to_unicode be more graceful for non-unicode strings, as like CMFPlone's
  safe_unicode does it.
  [thet]

Update to 3.4:

3.4 (2013-04-24)
----------------

- Switch to unicode internally. This should fix all en/decoding errors.
  [thet]

- Support for non-ascii parameter values. Fixes #88.
  [warvariuc]

- Added functions to transform chars in string with '\\' + any of r'\,;:' chars
  into '%{:02X}' form to avoid splitting on chars escaped with '\\'.
  [warvariuc]

- Allow seconds in vUTCOffset properties. Fixes #55.
  [thet]

- Let ``Component.decode`` better handle vRecur and vDDDLists properties.
  Fixes #70.
  [thet]

- Don't let ``Component.add`` re-encode already encoded values. This simplifies
  the API, since there is no need explicitly pass ``encode=False``. Fixes #82.
  [thet]

- Rename tzinfo_from_dt to tzid_from_dt, which is what it does.
  [thet]

- More support for dateutil parsed tzinfo objects. Fixes #89.
  [leo-naeka]

- Remove python-dateutil version fix at all. Current python-dateutil has Py3
  and Py2 compatibility.
  [thet]

- Declare the required python-dateutil dependency in setup.py. Fixes #90.
  [kleink]

Bump PKGREVISION for readded py-pytz dependency.

Put back the dependency on py-pytz which is still used by py-icalendar;
apparently the previous tests-only dependency on py-dateutil has
crept into the library sources but install_requires wasn't updated
to reflect this.

Per discussion with wiz.

This now needs py-dateutil instead of py-pytz. Bump PKGREVISION.

Missed in previous: Define empty USE_LANGUAGES.

Update py-icalendar to 3.3.

3.3 (2013-02-08)
----------------

* Drop support for Python < 2.6.
  [thet]

* Allow vGeo to be instantiated with list and not only tuples of geo
  coordinates. Fixes #83.
  [thet]

* Don't force to pass a list to vDDDLists and allow setting individual RDATE
  and EXDATE values without having to wrap them in a list.
  [thet]

* Fix encoding function to allow setting RDATE and EXDATE values and not to
  have bypass encoding with an icalendar property.
  [thet]

* Allow setting of timezone for vDDDLists and support timezone properties for
  RDATE and EXDATE component properties.
  [thet]

* Move setting of TZID properties to vDDDTypes, where it belongs to.
  [thet]

* Use @staticmethod decorator instead of wrapper function.
  [warvariuc, thet]

* Extend quoting of parameter values to all of those characters: ",;: ’'".
  This fixes an outlook incompatibility with some characters. Fixes: #79,
  Fixes: #81.
  [warvariuc]

* Define VTIMETZONE subcomponents STANDARD and DAYLIGHT for RFC5545 compliance.
  [thet]

LICENSE changed to 2-clause-bsd back in in 3.0.1b2.

Update to 3.2:

3.2 (2012-11-27)
----------------

* Documentation file layout restructuring.
  [thet]

* Fix time support. vTime events can be instantiated with a datetime.time
  object, and do not inherit from datetime.time itself.
  [rdunklau]

* Correctly handle tzinfo objects parsed with dateutil. Fixes #77.
  [warvariuc, thet]

* Text values are escaped correclty. Fixes #74.
  [warvariuc]

* Returned old folding algorithm, as the current implementation fails in some
  cases. Fixes #72, Fixes #73.
  [warvariuc]

* Supports to_ical() on date/time properties for dates prior to 1900.
  [cdevienne]

Drop PKG_DESTDIR_SUPPORT setting, "user-destdir" is default these days.

Update to 3.1:

Changes in version 3.0
======================

API Change
----------

Since version we unified to icalendar de/serialization API to use only to_ical
(for writing an ical string from the internal representation) and from_ical
(for parsing an ical string into the internal representation).

to_ical is now used instead of the methods ical, string, as_string and instead
of string casting via __str__ and str.

from_ical is now used instead of from_string.

This change is a requirement for future Python 3 compatibility. Please update
your code to reflect to the new API.

Timezone support
----------------

Timezones are now fully supported in icalendar for serialization and
deserialization. We use the pytz library for timezone components of datetime
instances. The timezone identifiers must be valid pytz respectively Olson
database timezone identifiers. This can be a problem for 'GMT' identifiers,
which are not defined in the Olson database.

Instead of the own UTC tzinfo implementation we use pytz UTC tzinfo object now.


About this fork which is not a fork anymore
===========================================

Aim of this fork (not fork anymore, read further) was to bring this package up
to date with latest icalendar `RFC`_ specification as part of
`plone.app.event`_ project which goal is to bring recurrent evens to `Plone`_.

After some thoughts we (Plone developers involved with `plone.app.event`_) send
a suggestion to icalendar-dev@codespeak.net to take over mainaining of
`icalendar`_. Nobody object and since version 2.2 we are back to development.

3.1

    Make sure parameters to certain properties propagate to the
    ical output. [kanarip]
    Re-include doctests. [rnix]
    endure correct datatype at instance creation time in prop.vCalAddress
    and prop.vText. [rnix]
    Apply TZID parameter to datetimes parsed from RECURRENCE-ID
    [dbstovall]
    Localize datetimes for timezones to avoid DST transition errors.
    [dbstovall]
    Allow UTC-OFFSET property value data types in seconds, which
    follows RFC5545 specification. [nikolaeff]
    Remove utctz and normalized_timezone methods to simplify the
    codebase. The methods were too tiny to be useful and just used
    at one place. [thet]
    When using Component.add() to add icalendar properties, force
    a value conversion to UTC for CREATED, DTSTART and LAST-MODIFIED.
    The RFC expects UTC for those properties. [thet]
    Removed last occurrences of old API (from_string). [Rembane]
    Add
    listing. For example when parsing a text/calendar text including
    multiple components (e.g. a VCALENDAR with 5 VEVENTs), the
    previous situation required us to look over all properties in
    VEVENTs even if we just want the properties under the VCALENDAR
    component (VERSION, PRODID, CALSCALE, METHOD). [dmikurube]
    All unit tests fixed. [mikaelfrykholm]

3.0.1b2 (2012-03-01)

    For all TZID parameters in DATE-TIME properties, use timezone
    identifiers (e.g. Europe/Vienna) instead of timezone names
    (e.g. CET), as required by RFC5545. Timezone names are used
    together with timezone identifiers in the Timezone components.
    [thet]
    Timezone parsing, issues and test fixes. [mikaelfrykholm,
    garbas, tgecho]
    Since we use pytz for timezones, also use UTC tzinfo object
    from the pytz library instead of own implementation. [thet]

3.0.1b1 (2012-02-24)

    Update Release information. [thet]

3.0

    Add API for proper Timezone support. Allow creating ical
    DATE-TIME strings with timezone information from Python datetimes
    with pytz based timezone information and vice versa. [thet]
    Unify API to only use to_ical and from_ical and remove string
    casting as a requirement for Python 3 compatibility: New:
    to_ical. Old: ical, string, as_string and string casting via
    __str__ and str. New: from_ical. Old: from_string. [thet]

Update to 2.2.

2.2
---

* migration to https://github.com/collective/icalendar using svn2git preserving
  tags, branches and authors.
  [garbas]

* using tox for testing on python 2.4, 2.5, 2.6, 2.6.
  [garbas]

* fixed tests so they pass also under python 2.7.
  [garbas]

* running tests on https://jenkins.plone.org/job/icalendar (only 2.6 for now)
  with some other metrics (pylint, clonedigger, coverage).
  [garbas]

* review and merge changes from https://github.com/cozi/icalendar fork.
  [garbas]

* created sphinx documentation and started documenting development and goals.
  [garbas]

* hook out github repository to http://readthedocs.org service so sphinx
  documentation is generated on each commit (for master). Documentation can be
  visible on: http://readthedocs.org/docs/icalendar/en/latest/
  [garbas]

Update to 2.1:

2.1 (2009-12-14)
================

* Fix deprecation warnings about `object.__init__` taking no parameters.

* Set the VALUE parameter correctly for date values.

* Long binary data would be base64 encoded with newlines, which made the
  iCalendar files incorrect. (This still needs testing).

* Correctly handle content lines which include newlines.

Update to 2.0.1, prodded by Daniel A Graham, and include a portability
patch for Python 2.6 by him.

iCalendar 2.0.1 (2008-07-11)
============================

API Changes:

* EXDATE and RDATE now returns a vDDDLists object, which contains a list
  of vDDDTypes objects. This is do that EXDATE and RDATE can contain
  lists of dates, as per RFC.

  ***Note!***: This change is incompatible with earlier behavior, so if you
  handle EXDATE and RDATE you will need to update your code.

* When createing a vDuration of -5 hours (which in itself is nonsensical),
  the ical output of that was -P1DT19H, which is correct, but ugly. Now
  it's '-PT5H', which is prettier.

* Made the tests run under Python 2.5+

* Renamed the UTC class to Utc, so it would not clash with the UTC object,
  since that rendered the UTC object unpicklable.

Initial import of py-icalendar, packaged for pkgsrc-wip by mj_turner
with changed by jihbed.

The iCalendar package is a parser/generator of iCalendar files for
use with Python. It follows the RFC 2445 (iCalendar) specification

The package can both generate and parse iCalendar files, and can
easily be used as is.

The aim is to make a package that is fully compliant to RFC 2445,
well designed, simple to use and well documented.
