pathlibutil

---

pathlibutil.Path inherits from pathlib.Path with some useful built-in python functions.

• Path().hexdigest() to calculate and Path().verify() for verification of hexdigest from a file
• Path.default_hash to configurate default hash algorithm for Path class (default: 'md5')
• Path().size() to get size in bytes of a file or directory
• Path().read_lines() to yield over all lines from a file until EOF
• contextmanager to change current working directory with with statement

Installation

pip install pathlibutil

Usage

from pathlibutil import Path

readme = Path('README.md')

print(f'File size: {readme.size()} Bytes')
print(f'File sha1: {readme.hexdigest("sha1")}')

print('-- File content --')
for line in readme.read_lines(encoding='utf-8'):
    print(line, end='')
print('-- EOF --')

with readme.parent as cwd:
    print(f'Current working directory: {cwd}')

# Change default hash algorithm from md5 to sha1
Path.default_hash = 'sha1'

print(f'File verification: {readme.verify("add3f48fded5e0829a8e3e025e44c2891542c58e")}')

Examples

1. Read file line by line to stdout

   Path().read_lines()

2. Write calculated hash to file

   Path().hexdigest()

3. Read hashes from file for verification

   Path().verify() and contextmanager
