superpathlib 1.1.0

Extended Pathlib

Superpathlib

Superpathlib offers Path objects with functionality extended from pathlib to maximize your productivity with a minimal amount of code.

Usage

from plib import Path
path = Path(filename)

1) Use properties to read & write path content in different formats

• text
• byte_content
• lines
• yaml
• json
• numpy

examples:

path.json = {key: value}

for line in path.lines:
    if interesting(line):
        process(line)

2) Use instance properties to get/set file metadata:

• get:
  • size: filesize
  • is_root: whether the owner of the file is a root user
  • has_children: whether a path has children
  • number_of_children: number of children in a folder
  • filetype: content type of a file
• get & set:
  • mtime: modified time
  • tag: can be used for alternative ordering or metadata

examples:

path_new.mtime = path_old.mtime

if path.tag != skip_keyword and path.filetype == "video":
    process(path)

3) Use class properties to access commonly used folders:

• docs
• assets
• ..

example:

names_path = Path.assets / 'names'
names = names_path.lines

4) Use additional functionality

• find(): recursively find all paths under a root that match a condition (extra options available for performance optimization)
• rmtree(): remove directory recursively
• copy_to(dest): copy content to dest
• copy_properties_to(dest): recursively copy path properties (mtime, tag) to all n-level children of dest
• tempfile(): create temporary file that can be used as context manager
• unpack(): extract archive(zip, tar, ..) file to desired folder
• pop_parent(): remove first parent from path in filesystem
• from_uri(): create path object from uri string

examples:

with Path.tempfile() as tmp:
    do_work(logfile=tmp)
    log = tmp.text
process(log)

condition = lambda p: (p / '.git').exists()
for git_path in root.find(condition):
    process_git(git_path)

5) Enhance existing functionality

• Automatically create parents when writing files, creating new files, renaming files, ..
• Return default values when path does not exist (e.g. size = 0, lines=[])

6) Inherit from Path to define your own additional functionality:

example:

import plib

class Path(plib.Path):
    def count_children(self):
        return sum(1 for _ in self.iterdir())

This only works if you inherit from plib Path, not the standard library pathlib Path

Installation

pip install superpathlib

Install the packages corresponding with the properties you want to use

• e.g. PyYaml for yaml property
• Packages listed in requirements.txt
