=========
PyLoader.
=========
Python library for downloading files by URL's. Fast and easy. Uses only Python STDLIB.

----------
Examples.
----------

~~~~~~~~~~~~~~~~
Simple download.
~~~~~~~~~~~~~~~~

.. code :: python

   from pyloader import PyLoader


   url = 'https://yt3.ggpht.com/1yafclomM37uN64INRwmmWPC7kT0OXwx6W5Or4JRs5eRrlGAXYD2x6thKfyrK_mf493GkScfUV5P7g=s742-nd-v1'
   out = 'pic.png'

   file = PyLoader.download(url, out)

   print(f'{out} downloaded.')

~~~~~~~~~~~~~~~~~~~~~~~~~
No progress bar download.
~~~~~~~~~~~~~~~~~~~~~~~~~

.. code :: python

   from pyloader import PyLoader


   url = 'https://yt3.ggpht.com/1yafclomM37uN64INRwmmWPC7kT0OXwx6W5Or4JRs5eRrlGAXYD2x6thKfyrK_mf493GkScfUV5P7g=s742-nd-v1'
   out = 'pic.png'

   file = PyLoader.pdownload(url, out)

   for data in file:
      print(PyLoader.util_format(data))

~~~~~~~~~~~~~~~~~~
TQDM Progress Bar.
~~~~~~~~~~~~~~~~~~

.. code :: python

   from pyloader import PyLoader

   from tqdm import tqdm


   url = 'https://yt3.ggpht.com/1yafclomM37uN64INRwmmWPC7kT0OXwx6W5Or4JRs5eRrlGAXYD2x6thKfyrK_mf493GkScfUV5P7g=s742-nd-v1'
   out = 'pic.png'

   pic = PyLoader.pdownload(url, out)

   progress_bar = tqdm()

   for download_info in pic:
      if download_info:
         if progress_bar.total == None:
               progress_bar.total = download_info['totalbytes']

        progress_bar.update(download_info['size_written'])

As you see, using PyLoader is very easy.

.. code :: python

   # Static Functions & Variables (from pyloader import ...).
   VERSION = 1.0

   _percentage(current: int, maximal: int, _round: bool=False) -> int
   _convsize(_bytes: int, chunk: int=1024) -> str

   # PyLoader Functions & Variables (from pyloader import PyLoader).
   # All PyLoader functions and variables are static. It means you can call functions without initializing PyLoader.
   PyLoader.CHUNK = 1024

   PyLoader.temp_files = []

   @staticmethod PyLoader.download(url: str, out: str) -> bool
   @staticmethod PyLoader.pdownload(url: str, out: str, round_progress: bool=False) -> dict

   @staticmethod webfile(url: str, _type: str) -> str

   @staticmethod PyLoader.util_format(download_info: Union[bool, dict]) -> Union[bool, str]

   @staticmethod PyLoader.update_chunk(new_chunk: int) -> None

`VERSION`: Version of PyLoader.

`_percentage`: Calculate percentage. (_percentage:47, 100, True) -> 10%.<br>
`_convsize`: Converting bytes into another file sizes. (_convsize:1024) -> 1.0kb.

`PyLoader.CHUNK`: PyLoader default download chunk.

`PyLoader.temp_files`: Temporary files generated by `webfile`.

`PyLoader.download`: The "simple" download. Downloads file from URL into {out}. Already handles exceptions: HTTPError, URLError, SSLCertVerificationError, ValueError.

`PyLoader.pdownload`: Download file with ability to track things like: already downloaded percentage, downloaded bytes, file size, etc.

Yields ('yield [value]' in Python) dict with these values: 

percentage (downloaded percentage),
current_progress (current progress - downloaded bytes),
size_written (bytes was written in this chunk loading),
size (size of file),
totalbytes (size of file in bytes),
chunk (chunk),
time_wasted (wasted time to load chunk in nanoseconds),
success (is chunk loaded successfully).

Also handles exceptions: HTTPError, RequestHTTPError, RequestConnectionError, MissingSchema, (SSLError?).

`PyLoader.webfile`: Downloads file from URL and places downloaded into system temporary folder. Returns tuple with path to temporary file, is file downloaded successfully.
`PyLoader.clear_temp_files`: Clear temporary files generated by `webfile`.

`PyLoader.util_format`: Format download information. Converts dictionary with information to string. If ```download_info``` (first argument) is bool, function will return the same bool.

`PyLoader.update_chunk`: Update default PyLoader chunk.

-------
Notes.
-------
You can customize your progress bar just by using values from download information, you also can customize messages, etc by yourself, how to do it: `util_format` source code.
You also can use PyLoader static functions like _percentage, for your goals. These functions can be really useful.
Report any errors to project issues.
