hbutils.system.filesystem

Overview:

Utilities for filesystem.

touch

hbutils.system.filesystem.touch(file: str, exist_ok: bool = True, makedirs: bool = True)

Overview:

Touch the file at given path. Just like the touch command in unix system.

Parameters:

• file – Path of the file.

• exist_ok – Exist is okay or not.

• makedirs – Create directories when necessary.

Note

You can use this like touch command on unix.

Examples::

>>> import os
>>> from hbutils.system import touch
>>> os.listdir('.')
[]
>>> touch('simple.txt')  # touch simple file
>>> touch('1/2/3/simple.txt')  # touch file in nested directory (1/2/3 will be created)
>>> os.listdir('.')
['1', 'simple.txt']
>>> os.listdir('1/2/3')
['simple.txt']

glob

hbutils.system.filesystem.glob(*items) → Iterator[str]

Overview:

Glob filter by the given items.

Parameters:

items – Filter items.

Returns:

Filtered existing paths.

Note

glob() is different from native glob.glob, for its return value is a generator instead of list.

Examples::

>>> from hbutils.system import glob
>>>
>>> list(glob('*.md'))  # simple filter
['CONTRIBUTING.md', 'README.md']
>>> list(glob('*.md', '*.txt'))  # multiple filter
['CONTRIBUTING.md', 'README.md', 'requirements-test.txt', 'requirements-doc.txt', 'requirements.txt']
>>> print(*glob('hbutils/system/**/*.py'), sep='\n')  # nested filter

copy

hbutils.system.filesystem.copy(src1: str, src2: str, *srcn_dst: str)

Overview:

Copy files or directories.

No less than 2 arguments are accepted. When the last path is an existing path, all the fore paths will be copied to this path. Otherwise, the first path will be copied to the last path (exactly 2 arguments are accepted in this case, or NotADirectoryError will be raised).

From Stack Overflow - Copy file or directories recursively in Python.

Note

You can use this like cp -rf command on unix.

Examples::

>>> import os
>>> from hbutils.system import copy
>>>
>>> os.listdir('.')
['test', 'README.md', 'cloc.sh', 'LICENSE', 'codecov.yml', 'pytest.ini', 'Makefile', 'setup.py', 'requirements-test.txt', 'requirements-doc.txt', 'requirements.txt']
>>>
>>> copy('cloc.sh', 'new_cloc.sh')  # copy file
>>> copy('test', 'new_test')  # copy directory
>>> os.listdir('.')
['test', 'README.md', 'cloc.sh', 'LICENSE', 'codecov.yml', 'new_test', 'pytest.ini', 'Makefile', 'setup.py', 'requirements-test.txt', 'requirements-doc.txt', 'requirements.txt', 'new_cloc.sh']
>>>
>>> os.makedirs('new_path_1')
>>> copy('*.txt', 'new_path_1')  # copy to new path
>>> os.listdir('new_path_1')
['requirements-test.txt', 'requirements-doc.txt', 'requirements.txt']
>>>
>>> os.makedirs('new_path_2')
>>> copy('*.txt', 'test/system/**/*.py', 'new_path_2')  # copy plenty of files to new path
>>> print(*os.listdir('new_path_2'), sep='\n')

remove

hbutils.system.filesystem.remove(*files: str)

Overview:

Remove a file or a directory at file. file can be a file or a directory, both are supported.

Parameters:

files – Files or directories to be removed.

Note

You can use this like rm -rf command on unix.

Examples::

>>> import os
>>> from hbutils.system import remove
>>>
>>> os.listdir('.')
['test', 'README.md', 'cloc.sh', 'codecov.yml', 'new_test', 'new_path_2', 'setup.py', 'requirements-test.txt', 'new_path_1', 'requirements-doc.txt', 'requirements.txt', 'new_cloc.sh']
>>>
>>> remove('codecov.yml')  # remove file
>>> remove('new_test')  # remove directory
>>> os.listdir('.')
['test', 'README.md', 'cloc.sh', 'new_path_2', 'setup.py', 'requirements-test.txt', 'new_path_1', 'requirements-doc.txt', 'requirements.txt', 'new_cloc.sh']
>>>
>>> os.listdir('new_path_1')
['requirements-test.txt', 'requirements-doc.txt', 'requirements.txt']
>>> remove('new_path_1/*.txt')  # remove files from directory
>>> os.listdir('new_path_1')

>>> print(*os.listdir('new_path_2'), sep='\n')

getsize

hbutils.system.filesystem.getsize(*files: str)

Overview:

Get size of a file or a directory.

Parameters:

files – File paths.

Returns:

Size of the file or the total size of the directory.

Note

You can use this like du -sh command on unix.

>>> from hbutils.system import getsize
>>>
>>> getsize('README.md')  # a file
5368
>>> getsize('test')  # a directory
1575574
>>> getsize('hbutils/**/*.py')  # glob filtered files
