Customize the download bar

You have many options to customize your download bar.

Pay attention to the following example on how to change the characters of the download bar:

from dlbar import DownloadBar

download_bar = DownloadBar(
    empty_char='.',
    filled_char='>'
)

download_bar.download(
    url='https://url',
    dest='/a/b/c/downloaded_file.suffix',
    title='Downloading downloaded_file.suffix'
)

Output:

Downloading downloaded_file.suffix
63% >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>................... 284.590 MB/450.327 MB

You can even use ANSI codes to color the download bar characters:

from dlbar import DownloadBar

download_bar = DownloadBar(
    empty_char=f"\033[31m{chr(9472)}\033[0m",
    filled_char=f"\033[32m{chr(9472)}\033[0m"
)

download_bar.download(
    url='https://url',
    dest='/a/b/c/downloaded_file.suffix',
    title='Downloading downloaded_file.suffix'
)

Output:

You can also change the width of the download bar (any number greater than or equal to 10 is valid):

from dlbar import DownloadBar

download_bar = DownloadBar(width=35)

download_bar.download(
    url='https://url',
    dest='/a/b/c/downloaded_file.suffix',
    title='Downloading downloaded_file.suffix'
)

Output:

Downloading downloaded_file.suffix
12% ████------------------------------- 54.512 MB/450.327 MB

You can even hide the percentage or progress status of the download:

from dlbar import DownloadBar

download_bar = DownloadBar(percent=False)

download_bar.download(
    url='https://url',
    dest='/a/b/c/downloaded_file.suffix',
    title='Downloading downloaded_file.suffix'
)

Output:

Downloading downloaded_file.suffix
█████████████████████----------------------------- 197.777 MB/450.327 MB

You can also deal with attributes in the form of properties and change their values after creating an instance:

from dlbar import DownloadBar

download_bar = DownloadBar()

download_bar.status = False
download_bar.filled_char = '#'

download_bar.download(
    url='https://url',
    dest='/a/b/c/downloaded_file.suffix',
    title='Downloading downloaded_file.suffix'
)

Output:

Downloading downloaded_file.suffix
