Connect to a host using the TCP protocol.
This function implements the stateless version of the Happy Eyeballs algorithm (RFC
6555). If ``remote_host`` is a host name that resolves to multiple IP addresses,
each one is tried until one connection attempt succeeds. If the first attempt does
not connected within 250 milliseconds, a second attempt is started using the next
address in the list, and so on. On IPv6 enabled systems, an IPv6 address (if
available) is tried first.
When the connection has been established, a TLS handshake will be done if either
``ssl_context`` or ``tls_hostname`` is not ``None``, or if ``tls`` is ``True``.
:param remote_host: the IP address or host name to connect to
:param remote_port: port on the target host to connect to
:param local_host: the interface address or name to bind the socket to before connecting
:param tls: ``True`` to do a TLS handshake with the connected stream and return a

:param ssl_context: the SSL context object to use (if omitted, a default context is created)
:param tls_standard_compatible: If ``True``, performs the TLS shutdown handshake before closing
the stream and requires that the server does this as well. Otherwise,

Some protocols, such as HTTP, require this option to be ``False``.
See :meth:`~ssl.SSLContext.wrap_socket` for details.
:param tls_hostname: host name to check the server certificate against (defaults to the value
of ``remote_host``)
:param happy_eyeballs_delay: delay (in seconds) before starting the next connection attempt

# with yield is executed in the same contextvars context, so all values
# set in contextvars before yield is still available after yield as

This module started out as largely a copy paste from the stdlib's
optparse module with the features removed that we do not need from
optparse because we implement them in Click on a higher level (for
instance type handling, help formatting and a lot more).
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.

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.

variables. If this is `None` then reading

does not affect manually set environment
variables which are always read.
:param default_map: a dictionary (like object) with default values

format things wider than 80 characters by
default. In addition to that, formatters might

:param allow_extra_args: if this is set to `True` then extra arguments
at the end will not raise an error and will be

: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
specific command.

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.

#
# `getwch` does not share this probably-bugged behavior. Moreover, it
# returns a Unicode object by default, which is what we want.
#
# Either of these functions will return \x00 or \xe0 to indicate
# a special key, and you need to call the same function again to get
# the "rest" of the code. The fun part is that \u00e0 is
# "latin small letter a with grave", so if you type that on a French
# keyboard, you _also_ get a \xe0.
# E.g., consider the Up arrow. This returns \xe0 and then \x48. The
# resulting Unicode string reads as "a with grave" + "capital H".
# This is indistinguishable from when the user actually types
# "a with grave" and then "capital H".
#
# When \xe0 is returned, we assume it's part of a special-key sequence
# and call `getwch` again, but that means that when the user types
# the \u00e0 character, `getchar` doesn't return until a second
# character is typed.
# The alternative is returning immediately, but that would mess up
# cross-platform handling of arrow keys and others that start with
# \xe0. Another option is using `getch`, but then we can't reliably
# read non-ASCII characters, because return values of `getch` are
# limited to the current 8-bit codepage.

Pyperclip
A cross-platform clipboard module for Python, with copy & paste functions for plain text.
By Al Sweigart [email protected]
BSD License
Usage:
import pyperclip
pyperclip.copy('The text to be copied to the clipboard.')
spam = pyperclip.paste()
if not pyperclip.is_available():
print("Copy functionality unavailable!")
On Windows, no additional modules are needed.
On Mac, the pyobjc module is used, falling back to the pbcopy and pbpaste cli
commands. (These commands should come with OS X.).
On Linux, install xclip or xsel via package manager. For example, in Debian:
sudo apt-get install xclip
sudo apt-get install xsel
Otherwise on Linux, you will need the gtk or PyQt5/PyQt4 modules installed.
gtk and PyQt4 modules are not available for Python 3,
and this module does not work with PyGObject yet.
Note: There seems to be a way to get gtk on Python 3, according to:
https://askubuntu.com/questions/697397/python3-is-not-supporting-gtk-module
Cygwin is currently not supported.
Security Note: This module runs programs with these names:
- which
- where
- pbcopy
- pbpaste
- xclip
- xsel
- klipper
- qdbus
A malicious user could rename or add programs with these names, tricking
Pyperclip into running them with whatever permissions the Python process has.

created with the machine and process identity included.
`cover_pylib` is a boolean determining whether Python code installed
with the Python interpreter is measured. This includes the Python
standard library and any packages installed with the interpreter.
If `auto_data` is true, then any existing data file will be read when
coverage measurement starts, and data will be saved automatically when
measurement stops.
If `timid` is true, then a slower and simpler trace function will be
used. This is important for some environments where manipulation of
tracing functions breaks the faster trace function.
If `branch` is true, then branch coverage will be measured in addition
to the usual statement coverage.
`config_file` determines what configuration file to read:
* If it is ".coveragerc", it is interpreted as if it were True,
for backward compatibility.
* If it is a string, it is the name of the file to read. If the
file can't be read, it is an error.
* If it is True, then a few standard files names are tried
(".coveragerc", "setup.cfg", "tox.ini"). It is not an error for
these files to not be found.
* If it is False, then no configuration file is read.
`source` is a list of file paths or package names. Only code located
in the trees indicated by the file paths or package names will be
measured.
`source_pkgs` is a list of package names. It works the same as
`source`, but can be used to name packages where the name can also be
interpreted as a file path.
`include` and `omit` are lists of file name patterns. Files that match
`include` will be measured, files that match `omit` will not. Each
will also accept a single string argument.
`debug` is a list of strings indicating what debugging information is
desired.
`concurrency` is a string indicating the concurrency library being used
in the measured code. Without this, coverage.py will get incorrect
results if these libraries are in use. Valid strings are "greenlet",
"eventlet", "gevent", "multiprocessing", or "thread" (the default).
This can also be a list of these strings.
If `check_preimported` is true, then when coverage is started, the
already-imported files will be checked to see if they should be
measured by coverage. Importing measured files before coverage is
started can mean that code is missed.
`context` is a string to use as the :ref:`static context
<static_contexts>` label for collected data.
If `messages` is true, some messages will be printed to stdout
indicating what is happening.
