It's normally invisible to commands unless they opt-in to getting access to it. The context is useful as it can pass internal objects around and can control special execution features such as reading data from environment variables. A context can be used as context manager in which case it will call :meth:`close` on teardown. :param command: the command class for this context. :param parent: the parent context. :param info_name: the info name for this invocation. Generally this is the most descriptive name for the script or command. For the toplevel script it is usually the name of the script, for commands below it it's the name of the script. :param obj: an arbitrary object of user data. :param auto_envvar_prefix: the prefix to use for automatic environment variables. If this is `None` then reading from environment variables is disabled. This does not affect manually set environment variables which are always read. :param default_map: a dictionary (like object) with default values for parameters. :param terminal_width: the width of the terminal. The default is inherit from parent context. If no context defines the terminal width then auto detection will be applied. :param max_content_width: the maximum width for content rendered by Click (this currently only affects help pages). This defaults to 80 characters if not overridden. In other words: even if the terminal is larger than that, Click will not format things wider than 80 characters by default. In addition to that, formatters might add some safety mapping on the right. :param resilient_parsing: if this flag is enabled then Click will parse without any interactivity or callback invocation. Default values will also be ignored. This is useful for implementing things such as completion support. :param allow_extra_args: if this is set to `True` then extra arguments at the end will not raise an error and will be kept on the context. The default is to inherit from the command. :param allow_interspersed_args: if this is set to `False` then options and arguments cannot be mixed. The default is to inherit from the command. :param ignore_unknown_options: instructs click to ignore options it does not know and keeps them for later processing. :param help_option_names: optionally a list of strings that define how the default help parameter is named. The default is ``['--help']``. :param token_normalize_func: an optional function that is used to normalize tokens (options, choices, etc.). This for instance can be used to implement case insensitive behavior. :param color: controls if the terminal supports ANSI colors or not. The default is autodetection. This is only needed if ANSI codes are used in texts that Click prints which is by default not the case. This for instance would affect help output. :param show_default: Show defaults for all options. If not set, defaults to the value from a parent context. Overrides an option's ``show_default`` argument. .. versionchanged:: 8.0 The ``show_default`` parameter defaults to the value from the parent context. .. versionchanged:: 7.1 Added the ``show_default`` parameter. .. versionchanged:: 4.0 Added the ``color``, ``ignore_unknown_options``, and ``max_content_width`` parameters. .. versionchanged:: 3.0 Added the ``allow_extra_args`` and ``allow_interspersed_args`` parameters. .. versionchanged:: 2.0 Added the ``resilient_parsing``, ``help_option_names``, and ``token_normalize_func`` parameters. r �formatter_classNFr4 r0 �parent� info_name�obj�auto_envvar_prefix� default_map�terminal_width�max_content_width�resilient_parsing�allow_extra_args�allow_interspersed_args�ignore_unknown_options�help_option_names�token_normalize_func�color� show_defaultr/ c C s� || _ || _|| _i | _g | _g | _|d u r |d ur |j}|| _t|di �| _|d u r>|d ur>|d ur>|j d ur>|j � |�}|| _ d | _ |d u rO|d urO|j }|| _ |d u r]|d ur]|j }|| _ | d u rg|j} | | _| d u rq|j} | | _| d u r{|j} | | _| d u r�|d ur�|j} ndg} | | _|d u r�|d ur�|j}|| _| | _|d u r�|d ur�|jd ur�| jd ur�|j� d| j�� � �}n|�� }|d ur�|�dd�}|| _|d u r�|d ur�|j}|| _|d u r�|d ur�|j}|| _g | _d| _i | _t � | _ d S )N�metaz--help�_�-r ) rq r4 rr �params�args�protected_argsrs �getattr�_metaru �get�invoked_subcommandrv rw ry rz r{ r| r} rx rt �upper�replacer~ r �_close_callbacks�_depth�_parameter_sourcer � _exit_stack)�selfr4 rq rr rs rt ru rv rw rx ry rz r{ r| r} r~ r r; r; r< �__init__ s~ � �� zContext.__init__c C s$ | j �| �| j| j| j| j| jd�S )a* Gather information that could be useful for a tool generating user-facing documentation.

The default behavior of this is to invoke the cleanup functions which can be disabled by setting `cleanup` to `False`. The cleanup functions are typically used for things such as closing file handles. If the cleanup is intended the context object can also be directly used as a context manager. Example usage:: with ctx.scope(): assert get_current_context() is ctx This is equivalent:: with ctx: assert get_current_context() is ctx .. versionadded:: 5.0 :param cleanup: controls if the cleanup functions should be run or not. The default is to run these functions. In some situations the context only wants to be temporarily pushed in which case this can be disabled.

It exists so that click utilities can store some state here if they need to. It is however the responsibility of that code to manage this dictionary well. The keys are supposed to be unique dotted strings. For instance module paths are a good choice for it. What is stored in there is irrelevant for the operation of click. However what is important is that code that places data here adheres to the general semantics of the system. Example usage:: LANG_KEY = f'{__name__}.lang' def set_language(value): ctx = get_current_context() ctx.meta[LANG_KEY] = value def get_language(): return get_current_context().meta.get(LANG_KEY, 'en_US') .. versionadded:: 5.0 )r� r� r; r; r< r� � s z Context.metac C s | j | j| jd�S )a= Creates the :class:`~click.HelpFormatter` for the help and usage output.

The resource will be cleaned up when the context is popped. Uses :meth:`contextlib.ExitStack.enter_context`. It calls the resource's ``__enter__()`` method and returns the result. When the context is popped, it closes the stack, which calls the resource's ``__exit__()`` method. To register a cleanup function for something that isn't a context manager, use :meth:`call_on_close`. Or use something from :mod:`contextlib` to turn it into a context manager first. .. code-block:: python @click.group() @click.option("--name") @click.pass_context def cli(ctx): ctx.obj = ctx.with_resource(connect_db(name)) :param context_manager: The context manager to enter. :return: Whatever ``context_manager.__enter__()`` returns. .. versionadded:: 8.0 )r� � enter_context)r� r� r; r; r< � with_resource s zContext.with_resource�f.c C r� )a� Register a function to be called when the context tears down.

There are two ways to invoke this method: 1. the first argument can be a callback and all other arguments and keyword arguments are forwarded directly to the function. 2. the first argument is a click command object. In that case all arguments are forwarded as well but proper click parameters (options and click arguments) must be keyword arguments and Click will fill in defaults. Note that before Click 3.2 keyword arguments were not properly filled in against the intention of this code and no context was created. For more information about this change and why it was done in a bugfix release see :ref:`upgrade-to-3.2`. .. versionchanged:: 8.0 All ``kwargs`` are tracked in :attr:`params` so they will be passed if :meth:`forward` is called at multiple levels.

Most code will never use this as it does not implement a lot of useful functionality but it can act as the direct subclass of alternative parsing methods that do not depend on the Click parser. For instance, this can be used to bridge Click and other systems like argparse or docopt. Because base commands do not implement a lot of the API that other parts of Click take for granted, they are not supported for all operations. For instance, they cannot be used with the decorators usually and they have no built-in callback system. .. versionchanged:: 2.0 Added the `context_settings` parameter. :param name: the name of the command to use unless a group overrides it. :param context_settings: an optional dictionary with defaults that are passed to the context object. � context_classFTNr: �context_settingsr/ c C s || _ |d u r i }|| _d S rK )r: r� )r� r: r� r; r; r< r� F s zBaseCommand.__init__r, c C s d| j iS )ai Gather information that could be useful for a tool generating user-facing documentation.

This will always terminate the application after a call. If this is not wanted, ``SystemExit`` needs to be caught. This method is also available by directly calling the instance of a :class:`Command`. :param args: the arguments that should be used for parsing. If not provided, ``sys.argv[1:]`` is used. :param prog_name: the program name that should be used. By default the program name is constructed by taking the file name from ``sys.argv[0]``. :param complete_var: the environment variable that controls the bash completion support. The default is ``"_<prog_name>_COMPLETE"`` with prog_name in uppercase. :param standalone_mode: the default behavior is to invoke the script in standalone mode. Click will then handle exceptions and convert them into error messages and the function will never return but shut down the interpreter. If this is set to `False` they will be propagated to the caller and the return value of this function is the return value of :meth:`invoke`. :param windows_expand_args: Expand glob patterns, user dir, and env vars in command line args on Windows. :param extra: extra keyword arguments are forwarded to the context constructor. See :class:`Context` for more information. .. versionchanged:: 8.0.1 Added the ``windows_expand_args`` parameter to allow disabling command line arg expansion on Windows. .. versionchanged:: 8.0 When taking arguments from ``sys.argv`` on Windows, glob patterns, user dir, and env vars are expanded. .. versionchanged:: 3.0 Added the ``standalone_mode`` parameter.

Other subclasses are currently not supported by design as some of the internals for parsing are intentionally not finalized. Some settings are supported by both options and arguments. :param param_decls: the parameter declarations for this option or argument. This is a list of flags or argument names. :param type: the type that should be used. Either a :class:`ParamType` or a Python type. The later is converted into the former automatically if supported. :param required: controls if this is optional or not. :param default: the default value if omitted. This can also be a callable, in which case it's invoked when the default is needed without any arguments. :param callback: A function to further process or validate the value after type conversion. It is called as ``f(ctx, param, value)`` and must return the value. It is called for all sources, including prompts. :param nargs: the number of arguments to match. If not ``1`` the return value is a tuple instead of single value. The default for nargs is ``1`` (except if the type is a tuple, then it's the arity of the tuple). If ``nargs=-1``, all remaining parameters are collected. :param metavar: how the value is represented in the help page. :param expose_value: if this is `True` then the value is passed onwards to the command callback and stored on the context, otherwise it's skipped. :param is_eager: eager values are processed before non eager ones. This should not be set for arguments or it will inverse the order of processing. :param envvar: a string or list of strings that are environment variables that should be checked. :param shell_complete: A function that returns custom shell completions. Used instead of the param's type completion if given. Takes ``ctx, param, incomplete`` and must return a list of :class:`~click.shell_completion.CompletionItem` or a list of strings. .. versionchanged:: 8.0 ``process_value`` validates required parameters and bounded ``nargs``, and invokes the parameter callback before returning the value. This allows the callback to validate prompts. ``full_process_value`` is removed. .. versionchanged:: 8.0 ``autocompletion`` is renamed to ``shell_complete`` and has new semantics described above. The old name is deprecated and will be removed in 8.1, until then it will be wrapped to match the new requirements. .. versionchanged:: 8.0 For ``multiple=True, nargs>1``, the default must be a list of tuples. .. versionchanged:: 8.0 Setting a default is no longer required for ``nargs>1``, it will default to ``None``. ``multiple=True`` or ``nargs=-1`` will default to ``()``. .. versionchanged:: 7.1 Empty environment variables are ignored rather than taking the empty string value. This makes it possible for scripts to clear variables if they can't unset them. .. versionchanged:: 2.0 Changed signature for parameter callback to also be passed the parameter. The old callback format will still work, but it will raise a warning to give you a chance to migrate the code easier. � parameterNFT� param_declsrE r| �defaultr� �nargsrt �metavarr� r[ �envvarr r( �autocompletionr/ c s� | � |pd| �\| _| _| _t�||�| _|d u r$| jjr"| jj}nd}|| _ || _ || _ || _ | | _ || _| | _|| _| | _� d uradd l}|jdtdd� dtdd d td tjd f� fd d� } | | _ | jjr�|| jjkr�td| jj� d| j�d|� d���t|�s�|nd }|d ur�|r�z t t |�d �}W n t y� td�d �w |dkr�|d ur�zt |� W n t y� |r�d}nd}t|�d �w |dkr�t |�|kr�|r�dnd}td|� d|� d���d S d S d S d S d S )Nr; r r z�'autocompletion' is renamed to 'shell_complete'.

All other parameters are passed onwards to the parameter constructor. :param show_default: controls if the default value should be shown on the help page. Normally, defaults are not shown. If this value is a string, it shows the string instead of the value. This is particularly useful for dynamic options. :param show_envvar: controls if an environment variable should be shown on the help page. Normally, environment variables are not shown. :param prompt: if set to `True` or a non empty string then the user will be prompted for input. If set to `True` the prompt will be the option name capitalized. :param confirmation_prompt: Prompt a second time to confirm the value if it was prompted for. Can be set to a string instead of ``True`` to customize the message. :param prompt_required: If set to ``False``, the user will be prompted for input only when the option was specified as a flag without a value. :param hide_input: if this is `True` then the input on the prompt will be hidden from the user. This is useful for password input. :param is_flag: forces this option to act as a flag. The default is auto detection. :param flag_value: which value should be used for this flag if it's enabled. This is set to a boolean automatically if the option string contains a slash to mark two options. :param multiple: if this is set to `True` then the argument is accepted multiple times and recorded. This is similar to ``nargs`` in how it works but supports arbitrary number of arguments. :param count: this flag makes an option increment an integer. :param allow_from_autoenv: if this is enabled then the value of this parameter will be pulled from an environment variable in case a prefix is defined on the context. :param help: the help string. :param hidden: hide this option from help outputs. .. versionchanged:: 8.0.1 ``type`` is detected from ``flag_value`` if given. �optionNFTr� r r �confirmation_prompt�prompt_required� hide_inputrS � flag_valuert �count�allow_from_autoenvrE r r8 � show_choices� show_envvarry r/ c s d|v}t � j|f| | d�|�� |du r(| jd u r td��| j�dd��� }n |du r/d }nt�t|�}|| _ || _ || _ || _ || _ | j d uoL| j | _|d u re|d urYd}n| jr_d}nt| j�}n |du rq| jsq|d u| _|rx|rxd| _|d u r�| j }|r�| d u r�t�d |�| _|| _|o�t| jtj�| _|| _| | _| r�| d u r�tjdd �| _|r�d| _| | _ | | _ || _ || _ || _ | j!d kr�td ��| j r�| jr�| js�td ��| js�| jr�td ��| jr�| j r�| j d ur�td��| j�r| j"r�td��| j�rtd��d S d S )Nr� )rE rt Tz&'name' is required with 'prompt=True'.r� r� Fr )�minr� z&nargs=-1 is not supported for options.z+'prompt' is not valid for non-boolean flag.z1Secondary flag is not valid for non-boolean flag.z9'prompt' with 'hide_input' is not valid for boolean flag.z%'count' is not valid with 'multiple'.z$'count' is not valid with 'is_flag'.)#r7 r� r: r� r� � capitalizer1 r2 r� r r� r� r� r8 r rb rM r� r r� rE rS rC � BoolParamType� is_bool_flagr� r� �IntRanger� r r r� r� r� rt )r� r� r r r� r� r� rS r� rt r� r� rE r r8 r� r� ry �default_is_missing� prompt_textr9 r; r< r� � sz ��zOption.__init__c s0 t � �� }|j| j| j| j| j| j| jd� |S )N)r r rS r� r� r8 ) r7 r� r� r r rS r� r� r8 )r� r< r9 r; r< r� � s �zOption.to_info_dictr� r� c C sf g }g }d }g }|D ]e}|� � r |d ur td|� d���|}q |d d� dkr)dnd}||v rc|�|d�\} } | �� } | rI|�t| �� |�| � | �� } | rV|�| �� � | | krbtd|�d���q |�t|�� |�|� q |d u r�|r�|jdd � d � |d d � d d �� � }|� � s�d }|d u r�|s�d ||fS td��|s�|s�td|� d|� d���|||fS )NzName 'z' defined twicer �/�;zBoolean option z) cannot use the same flag for true/false.c S s t | d � S )Nr r� �r� r; r; r< �<lambda>' s z%Option._parse_decls.<locals>.<lambda>r_ r r� r� z#Could not determine name for optionz*No options defined but a name was passed (zH).
