If ``version`` is not provided, Click will try to detect it using :func:`importlib.metadata.version` to get the version for the ``package_name``. On Python < 3.8, the ``importlib_metadata`` backport must be installed. If ``package_name`` is not provided, Click will try to detect it by inspecting the stack frames.

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.

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.

It does not invoke the actual command callback though. To quickly customize the context class used without overriding this method, set the :attr:`context_class` attribute. :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's usually the name of the script, for commands below it it's the name of the command. :param args: the arguments to parse as list of strings. :param parent: the parent context if available. :param extra: extra keyword arguments forwarded to the context constructor. .. versionchanged:: 8.0 Added the :attr:`context_class` attribute. r� F�r� N)r� �itemsr� r� � parse_args)r� rr r� rq r� r` r� r, r; r; r< � make_contextn s" ���� ��zBaseCommand.make_contextc C r� )z�Given a context and a list of arguments this creates the parser and parses the arguments, then modifies the context as necessary.

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).

Validates and converts values from the command line or Python into the correct type.

This is already implemented by default. - :meth:`convert` must convert string values to the correct type. - :meth:`convert` must accept values that are already the correct type. - It must be able to convert a value if the ``ctx`` and ``param`` arguments are ``None``.

The format strings which are checked are configurable, but default to some common (non-timezone aware) ISO 8601 formats. When specifying *DateTime* formats, you should only pass a list or a tuple. Other iterables, like generators, may lead to surprising results. The format strings are processed using ``datetime.strptime``, and this consequently defines the format strings which are allowed. Parsing is tried using each format, in order, and the first format which parses successfully is used. :param formats: A list or tuple of date format strings, in the order in which they should be tried.

The file is automatically closed once the context tears down (after the command finished working). Files can be opened for reading or writing. The special value ``-`` indicates stdin or stdout depending on the mode. By default, the file is opened for reading text data, but it can also be opened in binary mode or for writing. The encoding parameter can be used to force a specific encoding. The `lazy` flag controls if the file should be opened immediately or upon first IO. The default is to be non-lazy for standard input and output streams as well as files opened for reading, `lazy` otherwise. When opening a file lazily for reading, it is still opened temporarily for validation, but will not be held open until first IO. lazy is mainly useful when opening for writing to avoid creating the file until it is needed. Starting with Click 2.0, files can also be opened atomically in which case all writes go into a separate file in the same folder and upon completion the file will be moved over to the original location. This is useful if a file regularly read by other users is modified.

First of all, instead of returning an open file handle it returns just the filename. Secondly, it can perform various basic checks about what the file or directory should be. :param exists: if set to true, the file or directory needs to exist for this value to be valid. If this is not required and a file does indeed not exist, then all further checks are silently skipped. :param file_okay: controls if a file is a possible value. :param dir_okay: controls if a directory is a possible value. :param writable: if true, a writable check is performed. :param readable: if true, a readable check is performed. :param resolve_path: if this is true, then the path is fully resolved before the value is passed onwards. This means that it's absolute and symlinks are resolved. It will not expand a tilde-prefix, as this is supposed to be done by the shell only. :param allow_dash: If this is set to `True`, a single dash to indicate standard streams is permitted. :param path_type: Convert the incoming path value to this type. If ``None``, keep Python's default, which is ``str``. Useful to convert to :class:`pathlib.Path`. .. versionchanged:: 8.0 Allow passing ``type=pathlib.Path``. .. versionchanged:: 6.0 Added the ``allow_dash`` parameter.

This works well in most cases, except for when `nargs` is set to a fixed count and different types should be used for different items. In this case the :class:`Tuple` type can be used. This type can only be used if `nargs` is set to a fixed number. For more information see :ref:`tuple-type`.

The default metadata is ``type`` to indicate special shell handling, and ``help`` if a shell supports showing a help string next to the value. Arbitrary parameters can be passed when creating the object, and accessed using ``item.attr``. If an attribute wasn't passed, accessing it returns ``None``. :param value: The completion suggestion. :param type: Tells the shell script to provide special completion support for the type. Click uses ``"dir"`` and ``"file"``. :param help: String shown next to the value if supported. :param kwargs: Arbitrary metadata. The built-in implementations don't use this, but custom type completions paired with custom shell support could use it. ��value�type�help�_info�plainNr r! r" �kwargsr c K � || _ || _|| _|| _d S �Nr )�selfr r! r" r% r r r �__init__L � zCompletionItem.__init__�namec C s | j �|�S r' )r# �get)r( r+ r r r � __getattr__X s zCompletionItem.__getattr__)r$ N) �__name__� __module__� __qualname__�__doc__� __slots__�t�Any�str�Optionalr) r- r r r r r 7 s" ����� � r a� %(complete_func)s() { local IFS=$'\n' local response response=$(env COMP_WORDS="${COMP_WORDS[*]}" COMP_CWORD=$COMP_CWORD %(complete_var)s=bash_complete $1) for completion in $response; do IFS=',' read type value <<< "$completion" if [[ $type == 'dir' ]]; then COMREPLY=() compopt -o dirnames elif [[ $type == 'file' ]]; then COMREPLY=() compopt -o default elif [[ $type == 'plain' ]]; then COMPREPLY+=($value) fi done return 0 } %(complete_func)s_setup() { complete -o nosort -F %(complete_func)s %(prog_name)s } %(complete_func)s_setup; a� #compdef %(prog_name)s %(complete_func)s() { local -a completions local -a completions_with_descriptions local -a response (( ! $+commands[%(prog_name)s] )) && return 1 response=("${(@f)$(env COMP_WORDS="${words[*]}" COMP_CWORD=$((CURRENT-1)) %(complete_var)s=zsh_complete %(prog_name)s)}") for type key descr in ${response}; do if [[ "$type" == "plain" ]]; then if [[ "$descr" == "_" ]]; then completions+=("$key") else completions_with_descriptions+=("$key":"$descr") fi elif [[ "$type" == "dir" ]]; then _path_files -/ elif [[ "$type" == "file" ]]; then _path_files -f fi done if [ -n "$completions_with_descriptions" ]; then _describe -V unsorted completions_with_descriptions -U fi if [ -n "$completions" ]; then compadd -U -V unsorted -a completions fi } compdef %(complete_func)s %(prog_name)s; a� function %(complete_func)s; set -l response; for value in (env %(complete_var)s=fish_complete COMP_WORDS=(commandline -cp) COMP_CWORD=(commandline -t) %(prog_name)s); set response $response $value; end; for completion in $response; set -l metadata (string split "," $completion); if test $metadata[1] = "dir"; __fish_complete_directories $metadata[2]; else if test $metadata[1] = "file"; __fish_complete_path $metadata[2]; else if test $metadata[1] = "plain"; echo $metadata[2]; end; end; end; complete --no-files --command %(prog_name)s --arguments "(%(complete_func)s)"; c @ s� e Zd ZU dZeje ed< eje ed< dedej eej f dededd f d d �Z e defd d ��Z dej eej f fdd�Zdefdd�Zdejeje ef fdd�Zdeje dedeje fdd�Zdedefdd�Zdefdd �Zd S ) � ShellCompletea� Base class for providing shell completion support.

The plan is to remove more and more from here over time. The reason this is a different module and not optparse from the stdlib is that there are differences in 2.x and 3.x about the error messages generated and optparse in the stdlib uses gettext for no good reason and might cause us issues. Click uses parts of optparse written by Gregory P. Ward and maintained by the Python Software Foundation. This is limited to code in parser.py. Copyright 2001-2006 Gregory P. Ward.

It's modelled after optparse and brings a similar but vastly simplified API. It should generally not be used directly as the high level Click classes wrap it for you. It's not nearly as extensible as optparse or argparse as it does not implement features that are implemented on a higher level (such as types or defaults). :param ctx: optionally the :class:`~click.Context` where this parser should go with.

The destination is not inferred (unlike with optparse) and needs to be explicitly provided. Action can be any of ``store``, ``store_const``, ``append``, ``append_const`` or ``count``.

It will either iterate over the `iterable` or `length` items (that are counted up). While iteration happens, this function will print a rendered progress bar to the given `file` (defaults to stdout) and will attempt to calculate remaining time and more. By default, this progress bar will not be rendered if the file is not a terminal. The context manager creates the progress bar. When the context manager is entered the progress bar is already created. With every iteration over the progress bar, the iterable passed to the bar is advanced and the bar is updated. When the context manager exits, a newline is printed and the progress bar is finalized on screen. Note: The progress bar is currently designed for use cases where the total progress can be expected to take at least several seconds. Because of this, the ProgressBar class object won't display progress that is considered too fast, and progress where the time between steps is less than a second. No printing must happen or the progress bar will be unintentionally destroyed. Example usage:: with progressbar(items) as bar: for item in bar: do_something_with(item) Alternatively, if no iterable is specified, one can manually update the progress bar through the `update()` method instead of directly iterating over the progress bar. The update method accepts the number of steps to increment the bar with:: with progressbar(length=chunks.total_bytes) as bar: for chunk in chunks: process_chunk(chunk) bar.update(chunks.bytes) The ``update()`` method also takes an optional value specifying the ``current_item`` at the new position. This is useful when used together with ``item_show_func`` to customize the output for each manual step:: with click.progressbar( length=total_size, label='Unzipping archive', item_show_func=lambda a: a.filename ) as bar: for archive in zip_file: archive.extract() bar.update(archive.size, archive) :param iterable: an iterable to iterate over. If not provided the length is required. :param length: the number of items to iterate over. By default the progressbar will attempt to ask the iterator about its length, which might or might not work. If an iterable is also provided this parameter can be used to override the length. If an iterable is not provided the progress bar will iterate over a range of that length. :param label: the label to show next to the progress bar. :param show_eta: enables or disables the estimated time display. This is automatically disabled if the length cannot be determined. :param show_percent: enables or disables the percentage display. The default is `True` if the iterable has a length or `False` if not. :param show_pos: enables or disables the absolute position display. The default is `False`. :param item_show_func: A function called with the current item which can return a string to show next to the progress bar. If the function returns ``None`` nothing is shown. The current item can be ``None``, such as when entering and exiting the bar. :param fill_char: the character to use to show the filled part of the progress bar. :param empty_char: the character to use to show the non-filled part of the progress bar. :param bar_template: the format string to use as template for the bar. The parameters in it are ``label`` for the label, ``bar`` for the progress bar and ``info`` for the info section. :param info_sep: the separator between multiple info items (eta etc.) :param width: the width of the progress bar in characters, 0 means full terminal width :param file: The file to write to. If this is not a terminal then only the label is printed. :param color: controls if the terminal supports ANSI colors or not. The default is autodetection. This is only needed if ANSI codes are included anywhere in the progress bar output which is not the case by default. :param update_min_steps: Render only when this many updates have completed. This allows tuning for very fast iterators. .. versionchanged:: 8.0 Output is shown even if execution time is less than 0.5 seconds. .. versionchanged:: 8.0 ``item_show_func`` shows the current item, not the previous one. .. versionchanged:: 8.0 Labels are echoed if the output is not a TTY. Reverts a change in 7.0 that removed all output. .. versionadded:: 8.0 Added the ``update_min_steps`` parameter. .. versionchanged:: 4.0 Added the ``color`` parameter.

Styles a text with ANSI styles and returns the new string. By default the styling is self contained which means that at the end of the string a reset code is issued. This can be prevented by passing ``reset=False``. Examples:: click.echo(click.style('Hello World!', fg='green')) click.echo(click.style('ATTENTION!', blink=True)) click.echo(click.style('Some things', reverse=True, fg='cyan')) click.echo(click.style('More colors', fg=(255, 12, 128), bg=117)) Supported color names: * ``black`` (might be a gray) * ``red`` * ``green`` * ``yellow`` (might be an orange) * ``blue`` * ``magenta`` * ``cyan`` * ``white`` (might be light gray) * ``bright_black`` * ``bright_red`` * ``bright_green`` * ``bright_yellow`` * ``bright_blue`` * ``bright_magenta`` * ``bright_cyan`` * ``bright_white`` * ``reset`` (reset the color code only) If the terminal supports it, color may also be specified as: - An integer in the interval [0, 255]. The terminal must support 8-bit/256-color mode. - An RGB tuple of three integers in [0, 255]. The terminal must support 24-bit/true-color mode. See https://en.wikipedia.org/wiki/ANSI_color and https://gist.github.com/XVilka/8346728 for more information. :param text: the string to style with ansi codes. :param fg: if provided this will become the foreground color. :param bg: if provided this will become the background color. :param bold: if provided this will enable or disable bold mode. :param dim: if provided this will enable or disable dim mode. This is badly supported. :param underline: if provided this will enable or disable underline. :param overline: if provided this will enable or disable overline. :param italic: if provided this will enable or disable italic. :param blink: if provided this will enable or disable blinking. :param reverse: if provided this will enable or disable inverse rendering (foreground becomes background and the other way round). :param strikethrough: if provided this will enable or disable striking through text. :param reset: by default a reset-all code is added at the end of the string which means that styles do not carry over. This can be disabled to compose styles. .. versionchanged:: 8.0 A non-string ``message`` is converted to a string. .. versionchanged:: 8.0 Added support for 256 and RGB color codes. .. versionchanged:: 8.0 Added the ``strikethrough``, ``italic``, and ``overline`` parameters. .. versionchanged:: 7.0 Added support for bright colors. .. versionadded:: 2.0 z[�mzUnknown color N� r � rq � � �5 �7 � � � � � � � � rl )rD rG �appendr� �KeyError� TypeError�_ansi_reset_allrE ) r< r� r� r� r� r� r� r� r� r� r� r$ �bitsr9 r9 r: �style� sF Z � � r� c C s t | �S )a Removes ANSI styling information from a string.

As such the following two calls are the same:: click.secho('Hello World!', fg='green') click.echo(click.style('Hello World!', fg='green')) All keyword arguments are forwarded to the underlying functions depending on which one they go with. Non-string types will be converted to :class:`str`. However, :class:`bytes` are passed directly to :meth:`echo` without applying style. If you want to style bytes that represent text, call :meth:`bytes.decode` first. .. versionchanged:: 8.0 A non-string ``message`` is converted to a string.

If an editor is given (should be the full path to the executable but the regular operating system search path is used for finding the executable) it overrides the detected editor. Optionally, some environment variables can be used. If the editor is closed without changes, `None` is returned. In case a file is edited directly the return value is always `None` and `require_save` and `extension` are ignored. If the editor cannot be opened a :exc:`UsageError` is raised. Note for Windows: to simplify cross-platform usage, the newlines are automatically converted from POSIX to Windows and vice versa. As such, the message here will have ``\n`` as newline markers. :param text: the text to edit. :param editor: optionally the editor to use. Defaults to automatic detection. :param env: environment variables to forward to the editor. :param require_save: if this is true, then not saving in the editor will make the return value become `None`. :param extension: the extension to tell the editor about. This defaults to `.txt` but changing this might change syntax highlighting. :param filename: if provided it will edit this file instead of the provided text contents.

Examples:: click.launch('https://click.palletsprojects.com/') click.launch('/my/downloaded/file', locate=True) .. versionadded:: 2.0 :param url: URL or filename of the thing to launch. :param wait: Wait for the program to exit before returning. This only works if the launched program blocks. In particular, ``xdg-open`` on Linux does not block. :param locate: if this is set to `True` then instead of launching the application associated with the URL it will attempt to launch a file manager with the file located.

This will always return a unicode character and under certain rare circumstances this might return more than one character. The situations which more than one character is returned is when for whatever reason multiple characters end up in the terminal buffer or standard input was not actually a terminal. Note that this will always read from the terminal, even if something is piped into the standard input. Note for Windows: in rare cases when typing non-ASCII characters, this function might wait for a second character and then return both at once. This is because certain Unicode characters look like special-key markers. .. versionadded:: 2.0 :param echo: if set to `True`, the character read will also show up on the terminal.

This should be used instead of :func:`print` because it provides better support for different data, files, and environments. Compared to :func:`print`, this does the following: - Ensures that the output encoding is not misconfigured on Linux. - Supports Unicode in the Windows console. - Supports writing to binary outputs, and supports writing bytes to text outputs. - Supports colors and styles on Windows. - Removes ANSI color and style codes if the output does not look like an interactive terminal. - Always flushes the output. :param message: The string or bytes to output. Other objects are converted to strings. :param file: The file to write to. Defaults to ``stdout``. :param err: Write to ``stderr`` instead of ``stdout``. :param nl: Print a newline after the message.

Files are opened non lazy by default. This can open regular files as well as stdin/stdout if ``'-'`` is passed. If stdin/stdout is returned the stream is wrapped so that the context manager will not close the stream accidentally.

The default behavior is to return whatever is most appropriate for the operating system. To give you an idea, for an app called ``"Foo Bar"``, something like the following folders could be returned: Mac OS X: ``~/Library/Application Support/Foo Bar`` Mac OS X (POSIX): ``~/.foo-bar`` Unix: ``~/.config/foo-bar`` Unix (POSIX): ``~/.foo-bar`` Windows (roaming): ``C:\Users\<user>\AppData\Roaming\Foo Bar`` Windows (not roaming): ``C:\Users\<user>\AppData\Local\Foo Bar`` .. versionadded:: 2.0 :param app_name: the application name. This should be properly capitalized and can contain whitespace. :param roaming: controls if the folder should be roaming or not on Windows.

It will either iterate over the `iterable` or `length` items (that are counted up). While iteration happens, this function will print a rendered progress bar to the given `file` (defaults to stdout) and will attempt to calculate remaining time and more. By default, this progress bar will not be rendered if the file is not a terminal. The context manager creates the progress bar. When the context manager is entered the progress bar is already created. With every iteration over the progress bar, the iterable passed to the bar is advanced and the bar is updated. When the context manager exits, a newline is printed and the progress bar is finalized on screen. Note: The progress bar is currently designed for use cases where the total progress can be expected to take at least several seconds. Because of this, the ProgressBar class object won't display progress that is considered too fast, and progress where the time between steps is less than a second. No printing must happen or the progress bar will be unintentionally destroyed. Example usage:: with progressbar(items) as bar: for item in bar: do_something_with(item) Alternatively, if no iterable is specified, one can manually update the progress bar through the `update()` method instead of directly iterating over the progress bar. The update method accepts the number of steps to increment the bar with:: with progressbar(length=chunks.total_bytes) as bar: for chunk in chunks: process_chunk(chunk) bar.update(chunks.bytes) The ``update()`` method also takes an optional value specifying the ``current_item`` at the new position. This is useful when used together with ``item_show_func`` to customize the output for each manual step:: with click.progressbar( length=total_size, label='Unzipping archive', item_show_func=lambda a: a.filename ) as bar: for archive in zip_file: archive.extract() bar.update(archive.size, archive) :param iterable: an iterable to iterate over. If not provided the length is required. :param length: the number of items to iterate over.

If an iterable is not provided the progress bar will iterate over a range of that length. :param label: the label to show next to the progress bar. :param show_eta: enables or disables the estimated time display. This is automatically disabled if the length cannot be determined. :param show_percent: enables or disables the percentage display. The default is `True` if the iterable has a length or `False` if not. :param show_pos: enables or disables the absolute position display. The default is `False`. :param item_show_func: A function called with the current item which can return a string to show next to the progress bar. If the function returns ``None`` nothing is shown. The current item can be ``None``, such as when entering and exiting the bar. :param fill_char: the character to use to show the filled part of the progress bar. :param empty_char: the character to use to show the non-filled part of the progress bar. :param bar_template: the format string to use as template for the bar. The parameters in it are ``label`` for the label, ``bar`` for the progress bar and ``info`` for the info section. :param info_sep: the separator between multiple info items (eta etc.) :param width: the width of the progress bar in characters, 0 means full terminal width :param file: The file to write to.
