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.

"""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
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.

for the script execution at every single level. 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 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.
.. versionchanged:: 8.1
The ``show_default`` parameter is overridden by
``Command.show_default``, instead of the other way around.

The ``show_default`` parameter defaults to the value from the

:class:`Option`\s or :class:`Argument`\s. 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.

# "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

# read non-ASCII characters, because return values of `getch` are

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

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.

"""
Many of these arguments duplicate and override values that can be
provided in a configuration file. Parameters that are missing here
will use values from the config file.
`data_file` is the base name of the data file to use. The config value
defaults to ".coverage". None can be provided to prevent writing a data
file. `data_suffix` is appended (with a dot) to `data_file` to create
the final file name. If `data_suffix` is simply True, then a suffix is
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.
.. versionadded:: 4.0
The `concurrency` parameter.
.. versionadded:: 4.2
The `concurrency` parameter can now be a list of strings.
.. versionadded:: 5.0
The `check_preimported` and `context` parameters.

The `source_pkgs` parameter.
.. versionadded:: 6.0
The `messages` parameter.

`should_trace` is a function, taking a file name and a frame, and
returning a `coverage.FileDisposition object`.
`check_include` is a function taking a file name and a frame. It returns
a boolean: True if the file should be traced, False if not.
`should_start_context` is a function taking a frame, and returning a
string. If the frame should be the start of a new context, the string
is the new context. If the frame should not be the start of a new
context, return None.
`file_mapper` is a function taking a filename, and returning a Unicode
filename. The result is the name that will be recorded in the data
file.
If `timid` is true, then a slower simpler trace function will be
used. This is important for some environments where manipulation of
tracing functions make the faster more sophisticated trace function not
operate properly.
If `branch` is true, then branches will be measured. This involves
collecting data on which statements followed each other (arcs). Use
`get_arc_data` to get the arc data.
`warn` is a warning function, taking a single string message argument
and an optional slug argument which will be a string or None, to be
used if a warning needs to be issued.
`concurrency` is a list of strings indicating the concurrency libraries
in use. Valid values are "greenlet", "eventlet", "gevent", or "thread"
(the default). Of these four values, only one can be supplied. Other

class CoverageData(SimpleReprMixin):
"""Manages collected coverage data, including file storage.
This class is the public supported API to the data that coverage.py
collects during program execution. It includes information about what code
was executed. It does not include information from the analysis phase, to
determine what lines could have been executed, or what lines were not
executed.
.. note::
The data file is currently a SQLite database file, with a
:ref:`documented schema <dbschema>`. The schema is subject to change
though, so be careful about querying it directly. Use this API if you
can to isolate yourself from changes.
There are a number of kinds of data that can be collected:
* **lines**: the line numbers of source lines that were executed.
These are always available.
* **arcs**: pairs of source and destination line numbers for transitions
between source lines. These are only available if branch coverage was
used.
* **file tracer names**: the module names of the file tracer plugins that
handled each file in the data.
Lines, arcs, and file tracer names are stored for each source file. File
names in this API are case-sensitive, even on platforms with
case-insensitive file systems.
A data file either stores lines, or arcs, but not both.
A data file is associated with the data when the :class:`CoverageData`
is created, using the parameters `basename`, `suffix`, and `no_disk`. The
base name can be queried with :meth:`base_filename`, and the actual file
name being used is available from :meth:`data_filename`.
To read an existing coverage.py data file, use :meth:`read`. You can then
access the line, arc, or file tracer data with :meth:`lines`, :meth:`arcs`,
or :meth:`file_tracer`.
The :meth:`has_arcs` method indicates whether arc data is available. You
can get a set of the files in the data with :meth:`measured_files`. As
with most Python containers, you can determine if there is any data at all
by using this object as a boolean value.
The contexts for each line in a file can be read with
:meth:`contexts_by_lineno`.
To limit querying to certain contexts, use :meth:`set_query_context` or
:meth:`set_query_contexts`. These will narrow the focus of subsequent
:meth:`lines`, :meth:`arcs`, and :meth:`contexts_by_lineno` calls. The set
of all measured context names can be retrieved with
:meth:`measured_contexts`.
Most data files will be created by coverage.py itself, but you can use
methods here to create data files if you like. The :meth:`add_lines`,
:meth:`add_arcs`, and :meth:`add_file_tracers` methods add data, in ways
that are convenient for coverage.py.
To record data for contexts, use :meth:`set_context` to set a context to
be used for subsequent :meth:`add_lines` and :meth:`add_arcs` calls.
To add a source file without any measured data, use :meth:`touch_file`,
or :meth:`touch_files` for a list of such files.
Write the data to its file with :meth:`write`.
You can clear the data in memory with :meth:`erase`. Two data collections
can be combined by using :meth:`update` on one :class:`CoverageData`,
passing it the other.
Data in a :class:`CoverageData` can be serialized and deserialized with
:meth:`dumps` and :meth:`loads`.
The methods used during the coverage.py collection phase
(:meth:`add_lines`, :meth:`add_arcs`, :meth:`set_context`, and
:meth:`add_file_tracers`) are thread-safe. Other methods may not be.

.. versionadded:: 4.0
Plug-in interfaces for coverage.py.
Coverage.py supports a few different kinds of plug-ins that change its
behavior:
* File tracers implement tracing of non-Python file types.
* Configurers add custom configuration, using Python code to change the
configuration.
* Dynamic context switchers decide when the dynamic context has changed, for
example, to record what test function produced the coverage.
To write a coverage.py plug-in, create a module with a subclass of
:class:`~coverage.CoveragePlugin`. You will override methods in your class to
participate in various aspects of coverage.py's processing.
Different types of plug-ins have to override different methods.
Any plug-in can optionally implement :meth:`~coverage.CoveragePlugin.sys_info`
to provide debugging information about their operation.
Your module must also contain a ``coverage_init`` function that registers an
instance of your plug-in class::
import coverage
class MyPlugin(coverage.CoveragePlugin):
...
def coverage_init(reg, options):
reg.add_file_tracer(MyPlugin())
You use the `reg` parameter passed to your ``coverage_init`` function to
register your plug-in object. The registration method you call depends on
what kind of plug-in it is.
If your plug-in takes options, the `options` parameter is a dictionary of your
plug-in's options from the coverage.py configuration file. Use them however
you want to configure your object before registering it.
Coverage.py will store its own information on your plug-in object, using
attributes whose names start with ``_coverage_``. Don't be startled.
.. warning::
Plug-ins are imported by coverage.py before it begins measuring code.
If you write a plugin in your own project, it might import your product
code before coverage.py can start measuring. This can result in your
own code being reported as missing.
One solution is to put your plugins in your project tree, but not in
your importable Python package.
.. _file_tracer_plugins:
File Tracers
============
File tracers implement measurement support for non-Python files. File tracers
implement the :meth:`~coverage.CoveragePlugin.file_tracer` method to claim
files and the :meth:`~coverage.CoveragePlugin.file_reporter` method to report
on those files.
In your ``coverage_init`` function, use the ``add_file_tracer`` method to
register your file tracer.
.. _configurer_plugins:
Configurers
===========
.. versionadded:: 4.5
Configurers modify the configuration of coverage.py during start-up.
Configurers implement the :meth:`~coverage.CoveragePlugin.configure` method to
change the configuration.
In your ``coverage_init`` function, use the ``add_configurer`` method to
register your configurer.
.. _dynamic_context_plugins:
Dynamic Context Switchers
=========================
.. versionadded:: 5.0
Dynamic context switcher plugins implement the
:meth:`~coverage.CoveragePlugin.dynamic_context` method to dynamically compute
the context label for each measured frame.
Computed context labels are useful when you want to group measured data without
modifying the source code.
For example, you could write a plugin that checks `frame.f_code` to inspect
the currently executed method, and set the context label to a fully qualified
method name if it's an instance method of `unittest.TestCase` and the method
name starts with 'test'. Such a plugin would provide basic coverage grouping
by test and could be used with test runners that have no built-in coveragepy
support.
In your ``coverage_init`` function, use the ``add_dynamic_context`` method to
register your dynamic context switcher.

the Python file name, and it maps it back to its original source

Python file. In this case, your plug-in implements
