.Synopsis
|
||||||
|
Activate a Python virtual environment for the current PowerShell session.
|
||||||
|
|
||||||
|
.Description
|
||||||
|
Pushes the python executable for a virtual environment to the front of the
|
||||||
|
$Env:PATH environment variable and sets the prompt to signify that you are
|
||||||
|
in a Python virtual environment. Makes use of the command line switches as
|
||||||
|
well as the `pyvenv.cfg` file values present in the virtual environment.
|
||||||
|
|
||||||
|
.Parameter VenvDir
|
||||||
|
Path to the directory that contains the virtual environment to activate. The
|
||||||
|
default value for this is the parent of the directory that the Activate.ps1
|
||||||
|
script is located within.
|
||||||
|
|
||||||
|
.Parameter Prompt
|
||||||
|
The prompt prefix to display when this virtual environment is activated. By
|
||||||
|
default, this prompt is the name of the virtual environment folder (VenvDir)
|
||||||
|
surrounded by parentheses and followed by a single space (ie. '(.venv) ').
|
||||||
|
|
||||||
|
.Example
|
||||||
|
Activate.ps1
|
||||||
|
Activates the Python virtual environment that contains the Activate.ps1 script.
|
||||||
|
|
||||||
|
.Example
|
||||||
|
Activate.ps1 -Verbose
|
||||||
|
Activates the Python virtual environment that contains the Activate.ps1 script,
|
||||||
|
and shows extra information about the activation as it executes.
|
||||||
|
|
||||||
|
.Example
|
||||||
|
Activate.ps1 -VenvDir C:\Users\MyUser\Common\.venv
|
||||||
|
Activates the Python virtual environment located in the specified location.
|
||||||
|
|
||||||
|
.Example
|
||||||
|
Activate.ps1 -Prompt "MyPython"
|
||||||
|
Activates the Python virtual environment that contains the Activate.ps1 script,
|
||||||
|
and prefixes the current prompt with the specified string (surrounded in
|
||||||
|
parentheses) while the virtual environment is active.
|
||||||
|
|
||||||
|
.Notes
|
||||||
|
On Windows, it may be required to enable this Activate.ps1 script by setting the
|
||||||
|
execution policy for the user. You can do this by issuing the following PowerShell
|
||||||
|
command:
|
||||||
|
|
||||||
|
PS C:\> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
|
||||||
|
|
||||||

.Description
|
||||||
|
Get-PyVenvConfig parses the values from the pyvenv.cfg file located in the
|
||||||
|
given folder, and returns them in a map.
|
||||||
|
|
||||||
|
For each line in the pyvenv.cfg file, if that line can be parsed into exactly
|
||||||
|
two strings separated by `=` (with any amount of whitespace surrounding the =)
|
||||||
|
then it is considered a `key = value` line. The left hand string is the key,
|
||||||
|
the right hand is the value.
|
||||||
|
|
||||||
|
If the value starts with a `'` or a `"` then the first and last character is
|
||||||
|
stripped from the value before being captured.
|
||||||
|
|

Flask
|
||||||
|
=====
|
||||||
|
|
||||||
|
Flask is a lightweight `WSGI`_ web application framework. It is designed
|
||||||
|
to make getting started quick and easy, with the ability to scale up to
|
||||||
|
complex applications. It began as a simple wrapper around `Werkzeug`_
|
||||||
|
and `Jinja`_ and has become one of the most popular Python web
|
||||||
|
application frameworks.
|
||||||
|
|
||||||
|
Flask offers suggestions, but doesn't enforce any dependencies or
|
||||||
|
project layout. It is up to the developer to choose the tools and
|
||||||
|
libraries they want to use. There are many extensions provided by the
|
||||||
|
community that make adding new functionality easy.

Jinja
|
||||||
|
=====
|
||||||
|
|
||||||
|
Jinja is a fast, expressive, extensible templating engine. Special
|
||||||
|
placeholders in the template allow writing code similar to Python
|
||||||
|
syntax. Then the template is passed data to render the final document.
|
||||||
|
|
||||||
|
It includes:
|
||||||
|
|
||||||
|
- Template inheritance and inclusion.
|
||||||
|
- Define and import macros within templates.
|
||||||
|
- HTML templates can use autoescaping to prevent XSS from untrusted
|
||||||
|
user input.
|
||||||
|
- A sandboxed environment can safely render untrusted templates.
|
||||||
|
- AsyncIO support for generating templates and calling async
|
||||||
|
functions.
|
||||||
|
- I18N support with Babel.
|
||||||
|
- Templates are compiled to optimized Python code just-in-time and
|
||||||
|
cached, or can be compiled ahead-of-time.
|
||||||
|
- Exceptions point to the correct line in templates to make debugging
|
||||||
|
easier.
|
||||||
|
- Extensible filters, tests, functions, and even syntax.
|
||||||
|
|
||||||
|
Jinja's philosophy is that while application logic belongs in Python if
|
||||||
|
possible, it shouldn't make the template designer's job difficult by
|
||||||
|
restricting functionality too much.

MarkupSafe
|
||||||
|
==========
|
||||||
|
|
||||||
|
MarkupSafe implements a text object that escapes characters so it is
|
||||||
|
safe to use in HTML and XML. Characters that have special meanings are
|
||||||
|
replaced so that they display as the actual characters. This mitigates
|
||||||
|
injection attacks, meaning untrusted user input can safely be displayed
|
||||||
|
on a page.

Werkzeug
|
||||||
|
========
|
||||||
|
|
||||||
|
*werkzeug* German noun: "tool". Etymology: *werk* ("work"), *zeug* ("stuff")
|
||||||
|
|
||||||
|
Werkzeug is a comprehensive `WSGI`_ web application library. It began as
|
||||||
|
a simple collection of various utilities for WSGI applications and has
|
||||||
|
become one of the most advanced WSGI utility libraries.
|
||||||
|
|
||||||
|
It includes:
|
||||||
|
|
||||||
|
- An interactive debugger that allows inspecting stack traces and
|
||||||
|
source code in the browser with an interactive interpreter for any
|
||||||
|
frame in the stack.
|
||||||
|
- A full-featured request object with objects to interact with
|
||||||
|
headers, query args, form data, files, and cookies.
|
||||||
|
- A response object that can wrap other WSGI applications and handle
|
||||||
|
streaming data.
|
||||||
|
- A routing system for matching URLs to endpoints and generating URLs
|
||||||
|
for endpoints, with an extensible system for capturing variables
|
||||||
|
from URLs.
|
||||||
|
- HTTP utilities to handle entity tags, cache control, dates, user
|
||||||
|
agents, cookies, files, and more.
|
||||||
|
- A threaded WSGI server for use while developing applications
|
||||||
|
locally.
|
||||||
|
- A test client for simulating HTTP requests during testing without
|
||||||
|
requiring running a server.
|
||||||
|
|
||||||
|
Werkzeug doesn't enforce any dependencies. It is up to the developer to
|
||||||
|
choose a template engine, database adapter, and even how to handle
|
||||||
|
requests. It can be used to build all sorts of end user applications
|
||||||
|
such as blogs, wikis, or bulletin boards.
|
||||||
|
|
||||||
|
`Flask`_ wraps Werkzeug, using it to handle the details of WSGI while
|
||||||
|
providing more structure and patterns for defining powerful
|
||||||
|
applications.

==========
|
||||||
|
|
||||||
|
Click is a Python package for creating beautiful command line interfaces
|
||||||
|
in a composable way with as little code as necessary. It's the "Command
|
||||||
|
Line Interface Creation Kit". It's highly configurable but comes with
|
||||||
|
sensible defaults out of the box.
|
||||||
|
|
||||||
|
It aims to make the process of writing command line tools quick and fun
|
||||||
|
while also preventing any frustration caused by the inability to
|
||||||
|
implement an intended CLI API.
|
||||||
|
|
||||||
|
Click in three points:
|
||||||
|
|
||||||
|
- Arbitrary nesting of commands
|
||||||
|
- Automatic help page generation
|
||||||
|
- Supports lazy loading of subcommands at runtime
|
||||||
|
|
||||||
|
|
||||||
|

Click is a simple Python module inspired by the stdlib optparse to make

writing command line scripts fun. Unlike other modules, it's based

around a simple API that does not come with too much magic and is

composable.

# 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

|
# 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.

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

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.

"""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.
|
||||||
|
|
||||||
