Parses & Formats integer file sizes to human readable file sizes.

To setup the project for development, run:

$ cd hfilesize/
$ pdm install

>>> from hfilesize import Format, FileSize
>>> FileSize('1k')
... 1000
>>> FileSize('1K')
... 1024
>>> FileSize('1kib')
... 1024
>>> FileSize('1K', default_binary=False, case_sensitive=False)
... 1000
>>> FileSize('1 kibibyte')
... 1024

>>> '{:d}'.format(FileSize(1024))
... '1024'
>>> '{:.02fH}'.format(FileSize(1024))
... '1 KB'
>>> '{:.02fHcv}'.format(FileSize(1024))
... '1 kilobyte'
>>> '{:.02fhs}'.format(FileSize(1000))
... '1 KB'
>>> '{:.02fhs^0}'.format(FileSize(1000))
... '1000 B'
>>> '{: >10.02fH}'.format(FileSize(1024))
... '      1 KB'

• case_sensitive: Use 1024 for upper case and 1000 for lower case if casing exists, as is common in unix utilities, e.g. dd

• default_binary: Default base if it is not clear what the unit is (i.e. if it is not 'mib' or 'mebibytes')

• format type: [hH][size_format][^exponent]
  • h: Base 1000
  • H: Base 1024
• size_format: c | cs | cv | e | ev | s | sv
  • c: Commonly used case-sensitive suffixes
  • cs: Commonly used abbreviated case-sensitive suffixes
  • cv: Commonly used verbose case-sensitive suffixes
  • e: IEC suffixes
  • ev: IEC verbose suffixes
  • s: SI suffixes
  • sv: SI verbose suffixes
• exponent: integer
