Motivation

Someday I made the script, that synchronizes two folders by date of theirs files. After time I've wanted to create package on PyPi. Also I've added some new features for work with files, in addition to syncing.

Build status

Here you can see build status of continuous integration/continuous deployment:

Code style

I'm using Codacy for automate my code quality.

Dependencies

You can see all dependencies from requirements.txt here.

Features

With my package you can sync two folders, manage logs files, delete empty folders and old files, read and create zip-archives.

Installation

First install Python.

If you don't have pip, install it.

Then type in terminal:

pip install sync-folders --upgrade

Importing

# Import module
from sync_folders import main, purgelog, cleaner

Fast usage

Synchronization

main.sync('./test_a', './test_b')
# Expected creation of `logs.txt`

Code Example

Here you can see the function, that syncs two folders

# Main function for synchronize two folders
def sync(path_a=None, path_b=None):
    if not path_a or not path_b:
        raise NameError('Required path to both dirs')
    logs = ''
    files_in_a = get_files(path_a)
    files_in_b = get_files(path_b)
    same_files = []
    for file_a in files_in_a:
        for file_b in files_in_b:
            if file_b['name'] == file_a['name']:
                # compare dates
                if file_b['date'] < file_a['date']:
                    # change
                    shutil.copy2(path_a + '/' + file_a['name'], path_b)
                    logs += f"Change {file_a['name']} in {path_b}" + '\n'
            same_files.append(file_b['name'])
    for file_a in files_in_a:
        if not file_a['name'] in same_files:
            # move to b
            shutil.copy2(path_a + '/' + file_a['name'], path_b)
            logs += f"Create {file_a['name']} in {path_b}" + '\n'

    write_file('./logs.txt', logs)

Tests

Unit-testing with pytest:

:smile:I give you the link to GitHub Actions, where you can see all my tests.
