+
+ 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 the default value for commands. If this
+ value is not set, it defaults to the value from the parent
+ context. ``Command.show_default`` overrides this default for the

+ """This function creates an iterable context manager that can be used
+ to iterate over something while showing a progress bar. 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

+ which is not the case by default.
