Changelog

8.1.0

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

Released 2022-03-28

-   Drop support for Python 3.6. :pr:`2129`
-   Remove previously deprecated code. :pr:`2130`

 -   ``Group.resultcallback`` is renamed to ``result_callback``.
 -   ``autocompletion`` parameter to ``Command`` is renamed to
     ``shell_complete``.
 -   ``get_terminal_size`` is removed, use
     ``shutil.get_terminal_size`` instead.
 -   ``get_os_args`` is removed, use ``sys.argv[1:]`` instead.

-   Rely on :pep:`538` and :pep:`540` to handle selecting UTF-8 encoding
 instead of ASCII. Click's locale encoding detection is removed.
 :issue:`2198`
-   Single options boolean flags with ``show_default=True`` only show
 the default if it is ``True``. :issue:`1971`
-   The ``command`` and ``group`` decorators can be applied with or
 without parentheses. :issue:`1359`
-   The ``Path`` type can check whether the target is executable.
 :issue:`1961`
-   ``Command.show_default`` overrides ``Context.show_default``, instead
 of the other way around. :issue:`1963`
-   Parameter decorators and ``group`` handles ``cls=None`` the same as
 not passing ``cls``. ``option`` handles ``help=None`` the same as
 not passing ``help``. :issue:`1959`
-   A flag option with ``required=True`` requires that the flag is
 passed instead of choosing the implicit default value. :issue:`1978`
-   Indentation in help text passed to ``Option`` and ``Command`` is
 cleaned the same as using the ``option`` and ``command``
 decorators does. A command's ``epilog`` and ``short_help`` are also
 processed. :issue:`1985`
-   Store unprocessed ``Command.help``, ``epilog`` and ``short_help``
 strings. Processing is only done when formatting help text for
 output. :issue:`2149`
-   Allow empty str input for ``prompt()`` when
 ``confirmation_prompt=True`` and ``default=""``. :issue:`2157`
-   Windows glob pattern expansion doesn't fail if a value is an invalid
 pattern. :issue:`2195`
-   It's possible to pass a list of ``params`` to ``command``. Any
 params defined with decorators are appended to the passed params.
 :issue:`2131`.
-   ``command`` decorator is annotated as returning the correct type if
 a ``cls`` argument is used. :issue:`2211`
-   A ``Group`` with ``invoke_without_command=True`` and ``chain=False``
 will invoke its result callback with the group function's return
 value. :issue:`2124`
-   ``to_info_dict`` will not fail if a ``ParamType`` doesn't define a
 ``name``. :issue:`2168`
-   Shell completion prioritizes option values with option prefixes over
 new options. :issue:`2040`
-   Options that get an environment variable value using
 ``autoenvvar_prefix`` treat an empty value as ``None``, consistent
 with a direct ``envvar``. :issue:`2146`

8.0.4

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

Released 2022-02-18

-   ``open_file`` recognizes ``Path("-")`` as a standard stream, the
 same as the string ``"-"``. :issue:`2106`
-   The ``option`` and ``argument`` decorators preserve the type
 annotation of the decorated function. :pr:`2155`
-   A callable default value can customize its help text by overriding
 ``__str__`` instead of always showing ``(dynamic)``. :issue:`2099`
-   Fix a typo in the Bash completion script that affected file and
 directory completion. If this script was generated by a previous
 version, it should be regenerated. :issue:`2163`
-   Fix typing for ``echo`` and ``secho`` file argument.
 :issue:`2174, 2185`

8.0.3

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

Released 2021-10-10

-   Fix issue with ``Path(resolve_path=True)`` type creating invalid
 paths. :issue:`2088`
-   Importing ``readline`` does not cause the ``confirm()`` prompt to
 disappear when pressing backspace. :issue:`2092`
-   Any default values injected by ``invoke()`` are cast to the
 corresponding parameter's type. :issue:`2089, 2090`

8.0.2

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

Released 2021-10-08

-   ``is_bool_flag`` is not set to ``True`` if ``is_flag`` is ``False``.
 :issue:`1925`
-   Bash version detection is locale independent. :issue:`1940`
-   Empty ``default`` value is not shown for ``multiple=True``.
 :issue:`1969`
-   Fix shell completion for arguments that start with a forward slash
 such as absolute file paths. :issue:`1929`
-   ``Path`` type with ``resolve_path=True`` resolves relative symlinks
 to be relative to the containing directory. :issue:`1921`
-   Completion does not skip Python's resource cleanup when exiting,
 avoiding some unexpected warning output. :issue:`1738, 2017`
-   Fix type annotation for ``type`` argument in ``prompt`` function.
 :issue:`2062`
-   Fix overline and italic styles, which were incorrectly added when
 adding underline. :pr:`2058`
-   An option with ``count=True`` will not show "[x>=0]" in help text.
 :issue:`2072`
-   Default values are not cast to the parameter type twice during
 processing. :issue:`2085`
-   Options with ``multiple`` and ``flag_value`` use the flag value
 instead of leaving an internal placeholder. :issue:`2001`

8.0.1

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

Released 2021-05-19

-   Mark top-level names as exported so type checking understand imports
 in user projects. :issue:`1879`
-   Annotate ``Context.obj`` as ``Any`` so type checking allows all
 operations on the arbitrary object. :issue:`1885`
-   Fix some types that weren't available in Python 3.6.0. :issue:`1882`
-   Fix type checking for iterating over ``ProgressBar`` object.
 :issue:`1892`
-   The ``importlib_metadata`` backport package is installed on Python <
 3.8. :issue:`1889`
-   Arguments with ``nargs=-1`` only use env var value if no command
 line values are given. :issue:`1903`
-   Flag options guess their type from ``flag_value`` if given, like
 regular options do from ``default``. :issue:`1886`
-   Added documentation that custom parameter types may be passed
 already valid values in addition to strings. :issue:`1898`
-   Resolving commands returns the name that was given, not
 ``command.name``, fixing an unintended change to help text and
 ``default_map`` lookups. When using patterns like ``AliasedGroup``,
 override ``resolve_command`` to change the name that is returned if
 needed. :issue:`1895`
-   If a default value is invalid, it does not prevent showing help
 text. :issue:`1889`
-   Pass ``windows_expand_args=False`` when calling the main command to
 disable pattern expansion on Windows. There is no way to escape
 patterns in CMD, so if the program needs to pass them on as-is then
 expansion must be disabled. :issue:`1901`

8.0.0

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

Released 2021-05-11

-   Drop support for Python 2 and 3.5.
-   Colorama is always installed on Windows in order to provide style
 and color support. :pr:`1784`
-   Adds a repr to Command, showing the command name for friendlier
 debugging. :issue:`1267`, :pr:`1295`
-   Add support for distinguishing the source of a command line
 parameter. :issue:`1264`, :pr:`1329`
-   Add an optional parameter to ``ProgressBar.update`` to set the
 ``current_item``. :issue:`1226`, :pr:`1332`
-   ``version_option`` uses ``importlib.metadata`` (or the
 ``importlib_metadata`` backport) instead of ``pkg_resources``. The
 version is detected based on the package name, not the entry point
 name. The Python package name must match the installed package
 name, or be passed with ``package_name=``. :issue:`1582`
-   If validation fails for a prompt with ``hide_input=True``, the value
 is not shown in the error message. :issue:`1460`
-   An ``IntRange`` or ``FloatRange`` option shows the accepted range in
 its help text. :issue:`1525`, :pr:`1303`
-   ``IntRange`` and ``FloatRange`` bounds can be open (``<``) instead
 of closed (``<=``) by setting ``min_open`` and ``max_open``. Error
 messages have changed to reflect this. :issue:`1100`
-   An option defined with duplicate flag names (``"--foo/--foo"``)
 raises a ``ValueError``. :issue:`1465`
-   ``echo()`` will not fail when using pytest's ``capsys`` fixture on
 Windows. :issue:`1590`
-   Resolving commands returns the canonical command name instead of the
 matched name. This makes behavior such as help text and
 ``Context.invoked_subcommand`` consistent when using patterns like
 ``AliasedGroup``. :issue:`1422`
-   The ``BOOL`` type accepts the values "on" and "off". :issue:`1629`
-   A ``Group`` with ``invoke_without_command=True`` will always invoke
 its result callback. :issue:`1178`
-   ``nargs == -1`` and ``nargs > 1`` is parsed and validated for
 values from environment variables and defaults. :issue:`729`
-   Detect the program name when executing a module or package with
 ``python -m name``. :issue:`1603`
-   Include required parent arguments in help synopsis of subcommands.
 :issue:`1475`
-   Help for boolean flags with ``show_default=True`` shows the flag
 name instead of ``True`` or ``False``. :issue:`1538`
-   Non-string objects passed to ``style()`` and ``secho()`` will be
 converted to string. :pr:`1146`
-   ``edit(require_save=True)`` will detect saves for editors that exit
 very fast on filesystems with 1 second resolution. :pr:`1050`
-   New class attributes make it easier to use custom core objects
 throughout an entire application. :pr:`938`

 -   ``Command.context_class`` controls the context created when
     running the command.
 -   ``Context.invoke`` creates new contexts of the same type, so a
     custom type will persist to invoked subcommands.
 -   ``Context.formatter_class`` controls the formatter used to
     generate help and usage.
 -   ``Group.command_class`` changes the default type for
     subcommands with ``group.command()``.
 -   ``Group.group_class`` changes the default type for subgroups
     with ``group.group()``. Setting it to ``type`` will create
     subgroups of the same type as the group itself.
 -   Core objects use ``super()`` consistently for better support of
     subclassing.

-   Use ``Context.with_resource()`` to manage resources that would
 normally be used in a ``with`` statement, allowing them to be used
 across subcommands and callbacks, then cleaned up when the context
 ends. :pr:`1191`
-   The result object returned by the test runner's ``invoke()`` method
 has a ``return_value`` attribute with the value returned by the
 invoked command. :pr:`1312`
-   Required arguments with the ``Choice`` type show the choices in
 curly braces to indicate that one is required (``{a|b|c}``).
 :issue:`1272`
-   If only a name is passed to ``option()``, Click suggests renaming it
 to ``--name``. :pr:`1355`
-   A context's ``show_default`` parameter defaults to the value from
 the parent context. :issue:`1565`
-   ``click.style()`` can output 256 and RGB color codes. Most modern
 terminals support these codes. :pr:`1429`
-   When using ``CliRunner.invoke()``, the replaced ``stdin`` file has
 ``name`` and ``mode`` attributes. This lets ``File`` options with
 the ``-`` value match non-testing behavior. :issue:`1064`
-   When creating a ``Group``, allow passing a list of commands instead
 of a dict. :issue:`1339`
-   When a long option name isn't valid, use ``difflib`` to make better
 suggestions for possible corrections. :issue:`1446`
-   Core objects have a ``to_info_dict()`` method. This gathers
 information about the object's structure that could be useful for a
 tool generating user-facing documentation. To get the structure of
 an entire CLI, use ``Context(cli).to_info_dict()``. :issue:`461`
-   Redesign the shell completion system. :issue:`1484`, :pr:`1622`

 -   Support Bash >= 4.4, Zsh, and Fish, with the ability for
     extensions to add support for other shells.
 -   Allow commands, groups, parameters, and types to override their
     completions suggestions.
 -   Groups complete the names commands were registered with, which
     can differ from the name they were created with.
 -   The ``autocompletion`` parameter for options and arguments is
     renamed to ``shell_complete``. The function must take
     ``ctx, param, incomplete``, must do matching rather than return
     all values, and must return a list of strings or a list of
     ``CompletionItem``. The old name and behavior is deprecated and
     will be removed in 8.1.
 -   The env var values used to start completion have changed order.
     The shell now comes first, such as ``{shell}_source`` rather
     than ``source_{shell}``, and is always required.

-   Completion correctly parses command line strings with incomplete
 quoting or escape sequences. :issue:`1708`
-   Extra context settings (``obj=...``, etc.) are passed on to the
 completion system. :issue:`942`
-   Include ``--help`` option in completion. :pr:`1504`
-   ``ParameterSource`` is an ``enum.Enum`` subclass. :issue:`1530`
-   Boolean and UUID types strip surrounding space before converting.
 :issue:`1605`
-   Adjusted error message from parameter type validation to be more
 consistent. Quotes are used to distinguish the invalid value.
 :issue:`1605`
-   The default value for a parameter with ``nargs`` > 1 and
 ``multiple=True`` must be a list of tuples. :issue:`1649`
-   When getting the value for a parameter, the default is tried in the
 same section as other sources to ensure consistent processing.
 :issue:`1649`
-   All parameter types accept a value that is already the correct type.
 :issue:`1649`
-   For shell completion, an argument is considered incomplete if its
 value did not come from the command line args. :issue:`1649`
-   Added ``ParameterSource.PROMPT`` to track parameter values that were
 prompted for. :issue:`1649`
-   Options with ``nargs`` > 1 no longer raise an error if a default is
 not given. Parameters with ``nargs`` > 1 default to ``None``, and
 parameters with ``multiple=True`` or ``nargs=-1`` default to an
 empty tuple. :issue:`472`
-   Handle empty env vars as though the option were not passed. This
 extends the change introduced in 7.1 to be consistent in more cases.
 :issue:`1285`
-   ``Parameter.get_default()`` checks ``Context.default_map`` to
 handle overrides consistently in help text, ``invoke()``, and
 prompts. :issue:`1548`
-   Add ``prompt_required`` param to ``Option``. When set to ``False``,
 the user will only be prompted for an input if no value was passed.
 :issue:`736`
-   Providing the value to an option can be made optional through
 ``is_flag=False``, and the value can instead be prompted for or
 passed in as a default value.
 :issue:`549, 736, 764, 921, 1015, 1618`
-   Fix formatting when ``Command.options_metavar`` is empty. :pr:`1551`
-   Revert adding space between option help text that wraps.
 :issue:`1831`
-   The default value passed to ``prompt`` will be cast to the correct
 type like an input value would be. :pr:`1517`
-   Automatically generated short help messages will stop at the first
 ending of a phrase or double linebreak. :issue:`1082`
-   Skip progress bar render steps for efficiency with very fast
 iterators by setting ``update_min_steps``. :issue:`676`
-   Respect ``case_sensitive=False`` when doing shell completion for
 ``Choice`` :issue:`1692`
-   Use ``mkstemp()`` instead of ``mktemp()`` in pager implementation.
 :issue:`1752`
-   If ``Option.show_default`` is a string, it is displayed even if
 ``default`` is ``None``. :issue:`1732`
-   ``click.get_terminal_size()`` is deprecated and will be removed in
 8.1. Use :func:`shutil.get_terminal_size` instead. :issue:`1736`
-   Control the location of the temporary directory created by
 ``CLIRunner.isolated_filesystem`` by passing ``temp_dir``. A custom
 directory will not be removed automatically. :issue:`395`
-   ``click.confirm()`` will prompt until input is given if called with
 ``default=None``. :issue:`1381`
-   Option prompts validate the value with the option's callback in
 addition to its type. :issue:`457`
-   ``confirmation_prompt`` can be set to a custom string. :issue:`723`
-   Allow styled output in Jupyter on Windows. :issue:`1271`
-   ``style()`` supports the ``strikethrough``, ``italic``, and
 ``overline`` styles. :issue:`805, 1821`
-   Multiline marker is removed from short help text. :issue:`1597`
-   Restore progress bar behavior of echoing only the label if the file
 is not a TTY. :issue:`1138`
-   Progress bar output is shown even if execution time is less than 0.5
 seconds. :issue:`1648`
-   Progress bar ``item_show_func`` shows the current item, not the
 previous item. :issue:`1353`
-   The ``Path`` param type can be passed ``path_type=pathlib.Path`` to
 return a path object instead of a string. :issue:`405`
-   ``TypeError`` is raised when parameter with ``multiple=True`` or
 ``nargs > 1`` has non-iterable default. :issue:`1749`
-   Add a ``pass_meta_key`` decorator for passing a key from
 ``Context.meta``. This is useful for extensions using ``meta`` to
 store information. :issue:`1739`
-   ``Path`` ``resolve_path`` resolves symlinks on Windows Python < 3.8.
 :issue:`1813`
-   Command deprecation notice appears at the start of the help text, as
 well as in the short help. The notice is not in all caps.
 :issue:`1791`
-   When taking arguments from ``sys.argv`` on Windows, glob patterns,
 user dir, and env vars are expanded. :issue:`1096`
-   Marked messages shown by the CLI with ``gettext()`` to allow
 applications to translate Click's built-in strings. :issue:`303`
-   Writing invalid characters  to ``stderr`` when using the test runner
 does not raise a ``UnicodeEncodeError``. :issue:`848`
-   Fix an issue where ``readline`` would clear the entire ``prompt()``
 line instead of only the input when pressing backspace. :issue:`665`
-   Add all kwargs passed to ``Context.invoke()`` to ``ctx.params``.
 Fixes an inconsistency when nesting ``Context.forward()`` calls.
 :issue:`1568`
-   The ``MultiCommand.resultcallback`` decorator is renamed to
 ``result_callback``. The old name is deprecated. :issue:`1160`
-   Fix issues with ``CliRunner`` output when using ``echo_stdin=True``.
 :issue:`1101`
-   Fix a bug of ``click.utils.make_default_short_help`` for which the
 returned string could be as long as ``max_width + 3``. :issue:`1849`
-   When defining a parameter, ``default`` is validated with
 ``multiple`` and ``nargs``. More validation is done for values being
 processed as well. :issue:`1806`
-   ``HelpFormatter.write_text`` uses the full line width when wrapping
 text. :issue:`1871`
