.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.
|
||||
|
||||
.Parameter ConfigDir

|
||||
Advanced Python Scheduler (APScheduler) is a Python library that lets you schedule your Python code
|
||||
to be executed later, either just once or periodically. You can add new jobs or remove old ones on
|
||||
the fly as you please. If you store your jobs in a database, they will also survive scheduler
|
||||
restarts and maintain their state. When the scheduler is restarted, it will then run all the jobs
|
||||
it should have run while it was offline [#f1]_.
|
||||
|
||||
Among other things, APScheduler can be used as a cross-platform, application specific replacement
|
||||
to platform specific schedulers, such as the cron daemon or the Windows task scheduler. Please
|
||||
note, however, that APScheduler is **not** a daemon or service itself, nor does it come with any
|
||||
command line tools. It is primarily meant to be run inside existing applications. That said,
|
||||
APScheduler does provide some building blocks for you to build a scheduler service or to run a
|
||||
dedicated scheduler process.
|
||||
|
||||
APScheduler has three built-in scheduling systems you can use:
|
||||
|
||||
* Cron-style scheduling (with optional start/end times)
|
||||
* Interval-based execution (runs jobs on even intervals, with optional start/end times)
|
||||
* One-off delayed execution (runs jobs once, on a set date/time)
|
||||
|
||||
You can mix and match scheduling systems and the backends where the jobs are stored any way you
|
||||
like. Supported backends for storing jobs include:
|
||||
|
||||
* Memory
|
||||
* `SQLAlchemy <http://www.sqlalchemy.org/>`_ (any RDBMS supported by SQLAlchemy works)
|
||||
* `MongoDB <http://www.mongodb.org/>`_
|
||||
* `Redis <http://redis.io/>`_
|
||||
* `RethinkDB <https://www.rethinkdb.com/>`_
|
||||
* `ZooKeeper <https://zookeeper.apache.org/>`_
|
||||
|
||||
APScheduler also integrates with several common Python frameworks, like:
|
||||
|
||||
* `asyncio <http://docs.python.org/3.4/library/asyncio.html>`_ (:pep:`3156`)
|
||||
* `gevent <http://www.gevent.org/>`_
|
||||
* `Tornado <http://www.tornadoweb.org/>`_
|
||||
* `Twisted <http://twistedmatrix.com/>`_
|
||||
* `Qt <http://qt-project.org/>`_ (using either
|
||||
`PyQt <http://www.riverbankcomputing.com/software/pyqt/intro>`_ ,
|
||||
`PySide6 <https://wiki.qt.io/Qt_for_Python>`_ ,
|
||||
`PySide2 <https://wiki.qt.io/Qt_for_Python>`_ or
|
||||
`PySide <http://qt-project.org/wiki/PySide>`_)
|
||||
|
||||
There are third party solutions for integrating APScheduler with other frameworks:
|
||||
|
||||
* `Django <https://github.com/jarekwg/django-apscheduler>`_
|
||||
* `Flask <https://github.com/viniciuschiele/flask-apscheduler>`_
|
||||
|
||||
|
||||
.. [#f1] The cutoff period for this is also configurable.

A. HISTORY OF THE SOFTWARE
|
||||
==========================
|
||||
|
||||
Python was created in the early 1990s by Guido van Rossum at Stichting
|
||||
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
|
||||
as a successor of a language called ABC. Guido remains Python's
|
||||
principal author, although it includes many contributions from others.
|
||||
|
||||
In 1995, Guido continued his work on Python at the Corporation for
|
||||
National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
|
||||
in Reston, Virginia where he released several versions of the
|
||||
software.
|
||||
|
||||
In May 2000, Guido and the Python core development team moved to
|
||||
BeOpen.com to form the BeOpen PythonLabs team. In October of the same
|
||||
year, the PythonLabs team moved to Digital Creations, which became
|
||||
Zope Corporation. In 2001, the Python Software Foundation (PSF, see
|
||||
https://www.python.org/psf/) was formed, a non-profit organization
|
||||
created specifically to own Python-related Intellectual Property.
|
||||
Zope Corporation was a sponsoring member of the PSF.
|
||||
|
||||
All Python releases are Open Source (see http://www.opensource.org for
|
||||
the Open Source Definition). Historically, most, but not all, Python
|
||||
releases have also been GPL-compatible; the table below summarizes
|
||||
the various releases.
|
||||
|
||||
Release Derived Year Owner GPL-
|
||||
from compatible? (1)
|
||||
|
||||
0.9.0 thru 1.2 1991-1995 CWI yes
|
||||
1.3 thru 1.5.2 1.2 1995-1999 CNRI yes
|
||||
1.6 1.5.2 2000 CNRI no
|
||||
2.0 1.6 2000 BeOpen.com no
|
||||
1.6.1 1.6 2001 CNRI yes (2)
|
||||
2.1 2.0+1.6.1 2001 PSF no
|
||||
2.0.1 2.0+1.6.1 2001 PSF yes
|
||||
2.1.1 2.1+2.0.1 2001 PSF yes
|
||||
2.1.2 2.1.1 2002 PSF yes
|
||||
2.1.3 2.1.2 2002 PSF yes
|
||||
2.2 and above 2.1.1 2001-now PSF yes
|
||||
|
||||
Footnotes:
|
||||
|
||||
(1) GPL-compatible doesn't mean that we're distributing Python under
|
||||
the GPL. All Python licenses, unlike the GPL, let you distribute
|
||||
a modified version without making your changes open source. The
|
||||
GPL-compatible licenses make it possible to combine Python with
|
||||
other software that is released under the GPL; the others don't.
|
||||
|
||||
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
|
||||
because its license has a choice of law clause. According to
|
||||
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
|
||||
is "not incompatible" with the GPL.
|
||||
|
||||
Thanks to the many outside volunteers who have worked under Guido's
|
||||
direction to make these releases possible.
|
||||

Django
|
||||
======
|
||||
|
||||
Django is a high-level Python web framework that encourages rapid development
|
||||
and clean, pragmatic design. Thanks for checking it out.
|
||||
|
||||
All documentation is in the "``docs``" directory and online at
|
||||
https://docs.djangoproject.com/en/stable/. If you're just getting started,
|
||||
here's how we recommend you read the docs:
|
||||
|
||||
* First, read ``docs/intro/install.txt`` for instructions on installing Django.
|
||||
|
||||
* Next, work through the tutorials in order (``docs/intro/tutorial01.txt``,
|
||||
``docs/intro/tutorial02.txt``, etc.).
|
||||
|
||||
* If you want to set up an actual deployment server, read
|
||||
``docs/howto/deployment/index.txt`` for instructions.
|
||||
|
||||
* You'll probably want to read through the topical guides (in ``docs/topics``)
|
||||
next; from there you can jump to the HOWTOs (in ``docs/howto``) for specific
|
||||
problems, and check out the reference (``docs/ref``) for gory details.
|
||||
|
||||
* See ``docs/README`` for instructions on building an HTML version of the docs.
|
||||
|
||||
Docs are updated rigorously. If you find any problems in the docs, or think
|
||||
they should be clarified in any way, please take 30 seconds to fill out a
|
||||
ticket here: https://code.djangoproject.com/newticket
|
||||
|
||||
To get more help:
|
||||
|
||||
* Join the ``#django`` channel on ``irc.libera.chat``. Lots of helpful people
|
||||
hang out there. See https://web.libera.chat if you're new to IRC.
|
||||
|
||||
* Join the django-users mailing list, or read the archives, at
|
||||
https://groups.google.com/group/django-users.
|
||||
|
||||
To contribute to Django:
|
||||
|
||||
* Check out https://docs.djangoproject.com/en/dev/internals/contributing/ for
|
||||
information about getting involved.
|
||||
|
||||
To run Django's test suite:
|
||||
|
||||
* Follow the instructions in the "Unit tests" section of
|
||||
``docs/internals/contributing/writing-code/unit-tests.txt``, published online at
|
||||
https://docs.djangoproject.com/en/dev/internals/contributing/writing-code/unit-tests/#running-the-unit-tests

BLP1 files, used mostly in Warcraft III, are not fully supported.
|
||||
All types of BLP2 files used in World of Warcraft are supported.
|
||||
|
||||
The BLP file structure consists of a header, up to 16 mipmaps of the
|
||||
texture
|
||||
|
||||
Texture sizes must be powers of two, though the two dimensions do
|
||||
not have to be equal; 512x256 is valid, but 512x200 is not.
|
||||
The first mipmap (mipmap #0) is the full size image; each subsequent
|
||||
mipmap halves both dimensions. The final mipmap should be 1x1.
|
||||
|
||||
BLP files come in many different flavours:
|
||||
* JPEG-compressed (type == 0) - only supported for BLP1.
|
||||
* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
|
||||
array of 8-bit values, one per pixel, left to right, top to bottom.
|
||||
Each value is an index to the palette.
|
||||
* DXT-compressed (type == 1, encoding == 2):
|
||||
- DXT1 compression is used if alpha_encoding == 0.
|
||||
- An additional alpha bit is used if alpha_depth == 1.
|
||||
- DXT3 compression is used if alpha_encoding == 1.
|
||||
- DXT5 compression is used if alpha_encoding == 7.

Independence War 2: Edge Of Chaos - Texture File Format - 16 October 2001
|
||||
|
||||
The textures used for 3D objects in Independence War 2: Edge Of Chaos are in a
|
||||
packed custom format called FTEX. This file format uses file extensions FTC
|
||||
and FTU.
|
||||
* FTC files are compressed textures (using standard texture compression).
|
||||
* FTU files are not compressed.
|
||||
Texture File Format
|
||||
The FTC and FTU texture files both use the same format. This
|
||||
has the following structure:
|
||||
{header}
|
||||
{format_directory}
|
||||
{data}
|
||||
Where:
|
||||
{header} = {
|
||||
u32:magic,
|
||||
u32:version,
|
||||
u32:width,
|
||||
u32:height,
|
||||
u32:mipmap_count,
|
||||
u32:format_count
|
||||
}
|
||||
|
||||
* The "magic" number is "FTEX".
|
||||
* "width" and "height" are the dimensions of the texture.
|
||||
* "mipmap_count" is the number of mipmaps in the texture.
|
||||
* "format_count" is the number of texture formats (different versions of the
|
||||
same texture) in this file.
|
||||
|
||||
{format_directory} = format_count * { u32:format, u32:where }
|
||||
|
||||
The format value is 0 for DXT1 compressed textures and 1 for 24-bit RGB
|
||||
uncompressed textures.
|
||||
The texture data for a format starts at the position "where" in the file.
|
||||
|
||||
Each set of texture data in the file has the following structure:
|
||||
{data} = format_count * { u32:mipmap_size, mipmap_size * { u8 } }
|
||||
* "mipmap_size" is the number of bytes in that mip level. For compressed
|
||||
textures this is the size of the texture data compressed with DXT1. For 24 bit
|
||||
uncompressed textures, this is 3 * width * height. Following this are the image
|
||||
bytes for that mipmap level.
|
||||
|
||||
Note: All data is stored in little-Endian (Intel) byte order.
