Rejected-PEPs Changelog

0.9.8 & 0.9.7 Final

Release Date: 2023-01-19

New

• The register functions are backported from v1.0 in development. Examples:

  >>> import rejected_peps as rp
  >>> rp.pep211.PEP
  211
  >>> rp.register(211, 'product')
  >>> rp.product.PEP
  211
  >>> rp.register(211, 'pd')
  >>> rp.pd.PEP
  211
  >>> rp.get('pd').PEP
  211
  >>> rp.unregister('pd')
  >>> rp.pd
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    ...
  AttributeError: module 'rejected_peps' has no attribute 'pd'
  >>> rp.clear_register()
  >>> rp.product
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    ...
  AttributeError: module 'rejected_peps' has no attribute 'product'

Fixed

• pep249.apply is now thread safe.
• pep349.str, pep3140.str and pep349.str & pep3140.str no longer raise TypeError if the argument is a type.

0.9.6 Final

Release Date: 2023-01-05

Fixed

• pep3140.str and pep349.str & pep3140.str now correctly return the result for any mapping.

  For example:

  >>> from collections import defaultdict as d
  >>> pep3140.str(d(int, {'1': 2}))
  {1: 2}  # v0.9.5
  defaultdict(<class 'int'>, {1: 2})  # v0.9.6

0.9.5 Final

Release Date: 2023-01-04

Announcement

• Support for Python 3.8 is planned to be dropped on October 14, 2023; if you need extended support, please report it.

Fixed

• pep351.freeze now detects any sequence or mapping.
• pep351.freeze(…, allow_frozendict=True) no longer crashes if the pep416 import fails.

0.9.4 Final

Release Date: 2023-01-04

Improved

• Functions in pep313 are now cached.

0.9.3 Final

Release Date: 2023-01-03

Fixed

• Fix test.run(): it no longer exits when finished and can correctly run the tests in the module. You can override the non-exiting by specifying exit=True.

0.9.2 Final

Release Date: 2023-01-03

Improved

• Functions in __init__.py are now cached.

0.9.1 Final

Release Date: 2023-01-03

Improved

• Add tests for __init__.py.
• Functions in pep313 now reject 0 if pep336.isNone(zero) instead of just checking for the builtin None.

0.9.0 Final

Release Date: 2023-01-02

Breaking

• Remove search_one deprecated from v0.5; use search.one instead.

0.9.0 Beta 1

Release Date: 2023-01-01

Improved

• pep326.Min, pep326.Max and pep336.NoneType can now be hashed.
• DeprecationWarning is now changed to error; search_one will be removed in v0.9.

0.8.2 Final

Release Date: 2023-01-01

Happy New Year!

Improved

• pep326.Min, pep326.Max and pep336.NoneType can now be hashed.
• DeprecationWarning is now changed to default; search_one will be removed in v0.9.

0.9.0 Alpha 2

Release Date: 2022-12-30

New

• #7, #9: You can now combine PEPs 204 & 281 and 212 & 281; use r = pep204 & pep281.range and indices = pep212.indices & pep281.range, or rp.pep(204, 212, 281) to get a namespace with rliteral for PEP 204 and indices for PEP 212. You cannot directly combine PEPs 204 and 212.

0.9.0 Alpha 1

Release Date: 2022-12-30

New

• #7, #8: You can now combine PEPs 349 and 3140; use rp.pep(349, 3140).str or str = pep349.str & pep3140.str to let str() use str() on items and allow returning bytes.

0.8.1 Final

Release Date: 2022-12-29

Improved

• #6: pep349.str is now also a class, supporting isinstance and issubclass checks. In these two contexts, it behaves the same as builtins.str only; hence, isinstance('1', pep3140.str) returns True. Note that pep349.str(…) returns a builtins.str or builtins.bytes instance, so it's compatible.
• #6: pep349.str now accepts the str(bytes_or_buffer, encoding[, errors]) form; in these cases, it's interpreted as normal.

0.8.0 Final

Release Date: 2022-12-29

Improved

• pep204 no longer fails when imported if pep211 is unavailable; however, repr(pep204) still fails if pep211 is unavailable.

0.8.0 Candidate 1

Release Date: 2022-12-29

Improved

• #5: pep3140.str now handles recursive objects correctly by replacing them with …, just as the builtin str does.

• pep3140.str is now a class, supporting isinstance and issubclass checks. In these two contexts, it behaves the same as builtins.str; hence, isinstance('1', pep3140.str) returns True. Note that pep3140.str(…) returns a builtins.str instance, so it's compatible.

0.8.0 Beta 2

Release Date: 2022-12-29

Improved

• The order of the check for __andfunc__ in pep535.cmp is adjusted; now in A and B, A.__andfunc__ is checked before B.__randfunc__.
• The exception note is now added correctly in Python 3.11 when AttributeError is raised during the fallback in pep535.cmp.

0.8.0 Beta 1

Release Date: 2022-12-29

New

• Add support of PEP 535 — Rich comparison chaining.

0.7.2 Final

Release Date: 2022-12-29

Improved

• pep351.freeze doesn't import pep416 until needed (lazy import).
• Improve some error messages.

0.7.1 Final

Release Date: 2022-12-28

Breaking

• Support for Python 3.6 is officially dropped. The rejected_peps.pep204 format never worked since module __getattr__ was not added until 3.7, and 3.6 entered EOL on Dec. 23, 2021. Support for Python 3.7 will be dropped starting from Jan. 27, 2023.

0.7.0 Final

Release Date: 2022-12-28

Added

• Tests for PEPs 754 and 3140 are supported.

0.7.0 Candidate 1

Release Date: 2022-12-28

Fixed

• pep326.Min is no longer less than itself; pep326.Max is no longer greater than itself.

0.7.0 Beta 1

Release Date: 2022-12-28

New

• Tests for PEPs 204 to 559 are supported. Call rp.run to run the test suite.

Improved

• Update URLs in info() to the newest peps.python.org format.
• Add file parameter to pep259.print().
• Correct the error messages of pep303.divmod().
• Fix pep303.rdivmod(); the first argument is no longer touched.
• Add PEP constants to PEPs 259 and 313.
• Fix implementation of mode modern for 49+ in PEP 313.
• The parameter allow_frozendict of pep351.freeze() is keyword-only.
• pep294.original(s) and pep294.underscore(s) ensure that s is a str.

0.6.1 Final

Release Date: 2021-08-22

Fixed

• Fix a possible UnboundLocalError in pep294.apply().

Improved

• to_roman(x) now checks for x.__index__ before falling back to int(x) & int(x, 0).

0.6.0 Final

Release Date: 2021-08-22

Removed

• roman(), to_int() and zero deprecated for 5 versions in PEP 313 are removed. They were replaced by to_roman(), from_roman() and default_zero in v0.4.1.

0.6.0 Candidate 2

Release Date: 2021-08-22

Improved

• 3 leading underscores are now accepted in pep313.large_dict, e.g. ___D → 500,000,000,000.

Fixed

• Correct a typo in the PEP 335 warning message.
• Raise TypeError early in print() of PEP 259 when end is not None or a str to prevent unhelpful messages for str.startswith and incorrect usage of non str-subclass startswith methods.

0.6.0 Candidate 1

Release Date: 2021-08-22

Breaking

• The PEP 294 implementation is rewritten.
  • Importing pep294 no longer directly sets attributes of the types module. The original behavior is fragile, surprising and requires importlib.reload(pep294) to rerun the code.
  • Instead, the apply(module=None, *, rename=pep294.underscore, strict=None) function is added. ¹
    • module defaults to types when it's None, otherwise attributes of it are set.
    • rename is a function that handles invalid names (i.e. a keyword or not an identifier). For example, LambdaType is converted to lambda, which is invalid. rename(name) returns the new variant.
    • strict is a bool or None. If strict is None, it is False if rename is pep294.original, else True. If it's true and the new name is not a str or invalid, TypeError or ValueError is raised depending on the error. rename is always called before checking.
    • This function returns None since it is an in-place operation on module.
  • The underscore(s), title(s) and original(s) functions are for the rename parameter.
    • underscore appends an underscore (_) to the name. For example, lambda → lambda_. This is the default value.
    • title is an alias of str.title. For example, lambda → Lambda.
    • original just returns the name unchanged. This is usually used when attributes aren't meant to be accessed by the types.x syntax, but getattr(types, 'x') etc.

Improved

• DeprecationWarning is now issued instead of Warning in PEP 335 if NotImplemented is returned. This matches the behavior starting from Python 3.9, and allows controlling it without effecting other Warning subclasses.
• Since it's a singleton, hash(pep335.NeedOtherOperand) now returns the hash of it's ID, rather than the fixed value 9223363241139.

Deprecated

• The filter action of DeprecationWarning is now turned to always since old names in pep313 were deprecated in v0.4.1 and removal is scheduled on v0.6. roman(), to_int() and zero will be removed in v0.6.0 final. Please make sure you use the new names to_roman(), from_roman() and default_zero.

Fixed

• The Python DeprecationWarning is now silenced in pep335 since it's already issued manually. Note that DeprecationWarning in NOT(NotImplemented) is still the builtin one.

0.5.0 Final

Release Date: 2021-08-11

New

• Add support of PEP 335 — Overloadable Boolean Operators Operator Functions.
• The new search.one is now preferred over search_one.
• Add search.any and search.one.any to match titles that contain any of the arguments. The default behavior is still all of them.

0.4.2 Final

Release Date: 2021-08-11

New

• Rejected-PEPs is now typed! See PEP 484 for more information about typing.

Improved

• info() now raises rejected_peps.UnavailableError if a PEP is supported but info is unavailable. It is a subclass of NotImplementedError and LookupError, so previous code catching NotImplementedError won't break.
• Improve some documentation to be clearer.

0.4.1 Final

Release Date: 2021-08-09

Breaking

• The support of PEP 313 has underwent some major changes.
  • roman() is renamed to to_roman(). The original name is deprecated and will be removed in v0.6.
  • to_int() is renamed to from_roman(). The original name is deprecated and will be removed in v0.6.
  • zero is renamed to default_zero. The original name is deprecated and will be removed in v0.6.
  • from_roman() now supports parsing roman fractions.

Improved

• A minor cleanup was done for some files (removing unneeded imports etc.).

0.4.0 Final

Release Date: 2021-08-09

New

• Add support of PEP 313 — Adding Roman Numeral Literals Functions to Python

Footnotes

1. There is a built-in apply() function in Python 2.x, but anyway we didn't support 2.x from the start, and apply is just a name, not a keyword. ↩
