cengal-app-dir-path-finder 1.1.0

Offering a unified API for easy retrieval of OS-specific application directories, enhancing data management across Windows, Linux, and macOS

cengal_app_dir_path_finder package

cengal_app_dir_path_finder is a cross-platform Python module designed to simplify the process of locating OS-recommended directories for application data, cache, logs, and more. It seamlessly integrates with Windows, Linux, and macOS, utilizing platform-specific standards like KNOWNFOLDERID constants on Windows, XDG standards on Linux, and NSSearchPathForDirectoriesInDomains on macOS. This module offers a unified API for accessing various types of directories, such as local, roaming, and program-specific paths, enhancing application compatibility and data management across different operating systems.

Installation

pip install cengal_app_dir_path_finder

Documentation

Import

from cengal_app_dir_path_finder import AppDirectoryType, AppDirPath

Usage

import os
from cengal_app_dir_path_finder import AppDirectoryType, AppDirPath

app_dir_path: AppDirPath = AppDirPath()
local_data_dir_path: str = app_dir_path(AppDirectoryType.local_data, 'MyApplicationName')
settings_json_path: str = os.path.join(local_data_dir_path, 'settings.json')
with open(settings_json_path, 'w') as file:
    file.write(my_app_settings)

API State

Stable. Guaranteed to not have braking changes in the future (see bellow for details).

Any hypothetical further API-breaking changes will lead to new module creation within the package. An old version will continue its existence and continue to be importable by an explicit address (see Details bellow).

Details

The current (currently latest) version can be imported either by:

from cengal_app_dir_path_finder import *

or by

from cengal_app_dir_path_finder.versions.v_0 import *

If further braking changes will be made to the API - a new (v_1) version will be made. As result:

Current (v_0) version will continue to be accessible by an explicit address:

from cengal_app_dir_path_finder.versions.v_0 import *

Latest (v_1) version will be accessible by either:

from cengal_app_dir_path_finder import *

or by

from cengal_app_dir_path_finder.versions.v_1 import *

This is a general approach across the entire Cengal library. It gives me the ability to effectively work on its huge codebase, even by myself.

By the way. I'm finishing an implementation of CengalPolyBuild - my package creation system which provides same approach to users. It is a comprehensive and hackable build system for multilingual Python packages: Cython (including automatic conversion from Python to Cython), C/C++, Objective-C, Go, and Nim, with ongoing expansions to include additional languages. Basically, it will provide easy access to all the same features I'm already using in the Cengal library package creation and management processes.

Static data

Short Description

• Purpose: To store data that remains unchanged throughout the application's lifecycle. This includes configuration files, default settings, templates, and read-only resources that are essential for the application's operation but do not require modification or updates after the initial deployment.
• Use Case: Particularly valuable for applications that rely on a set of immutable resources for functionality—such as image editing software that includes a library of default filters and effects, or a document processing application that uses a collection of templates for various document types. This ensures that these resources are available to the application regardless of user-specific data or settings, providing a consistent foundation upon which the application's features and functionalities operate.

User Program Files Common

Short Description

• Purpose: To store shared components, libraries, and resources for applications installed by the current user, promoting efficient use of storage by avoiding duplication and ensuring consistent access to shared resources.
• Use Case: Useful for applications that a user installs that need to share common files or components without affecting or requiring access to the system-wide common files directory. This setup is particularly beneficial in multi-user environments where each user has a distinct set of applications and configurations.

AppDirPath methods

__call__(...)

def __call__(self, dir_type: AppDirectoryType, app_name_or_path: Optional[DirNameOrPath] = None, with_structure: bool = True, ensure_dir: bool = True) -> str:

Constructs path of the requestet directory type taking into account provided application name.

• with_structure:
  • False: determines base directory provided by OS and followed with an application name
  • True: determines base directory provided by OS, followed with an application name and completed with a suffixes like 'cache', 'config', 'log', etc.
• ensure_dir:
  • True: creates directory sequence if does not exists

cached(...)

def cached(self, dir_type: AppDirectoryType, app_name_or_path: Optional[DirNameOrPath] = None, with_structure: bool = True, ensure_dir: bool = True) -> str:

Cached version. Much faster in a repetitive requests.

Global app instances of AppDirPath in Cengal library

An Instance service from the Cengal.Coroutines holds globally accessible instance of the AppDirPath as well as globally acessible field for an application name:

{
    ...
    'app_name': str(),
    'app_name_for_fs': str(),
    'app_version': tuple(),
    'app_version_str': str(),
    AppDirPath: AppDirPath(),
    'app_data_dir_path_type': AppDirectoryType.local_data,
    'app_cache_dir_path_type': AppDirectoryType.local_cache,
    'app_temp_dir_path_type': AppDirectoryType.local_temp,
    'app_log_dir_path_type': AppDirectoryType.local_log,
    'app_config_dir_path_type': AppDirectoryType.local_config,
    'app_runtime_dir_path_type': AppDirectoryType.local_runtime,
    ...
}

Several Cengal.Coroutines.Services using these fields and instances in their work. For example such services as db (async LMDB) and log.

Short example of proper usage:

from cengal_app_dir_path_finder import AppDirectoryType, AppDirPath
from cengal.parallel_execution.coroutines.coro_scheduler import cs_acoro
from cengal.parallel_execution.coroutines.coro_standard_services.instance import afast_wait, fast_get, fast_set
from uuid import uuid4


MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME: str = f'My Application Mandatory Configuration Complited {uuid4()}'


@cs_acoro
async def set_app_name(app_name: str) -> None:
    fast_set('app_name_for_fs', app_name)
    fast_set(MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME, None)


@cs_acoro
async def get_local_temp_dir() -> str:
    await afast_wait(MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME)
    app_dir_path: AppDirPath = fast_get(AppDirPath)
    return app_dir_path.cached(fast_get('app_temp_dir_path_type'), fast_get('app_name_for_fs'))

Same example but a bit faster in an execution performance terms:

from cengal.file_system.app_fs_structure.app_dir_path import AppDirectoryType, AppDirPath  # totaly the same import as in a previous example
from cengal.parallel_execution.coroutines.coro_scheduler import Interface
from cengal.parallel_execution.coroutines.coro_standard_services.instance import afast_wait_explicit, fast_get_explicit, fast_set_explicit
from uuid import uuid4


MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME: str = f'My Application Mandatory Configuration Complited {uuid4()}'


async def set_app_name(i: Interface, app_name: str) -> None:
    fast_set_explicit(i, 'app_name_for_fs', app_name)
    fast_set_explicit(i, MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME, None)


async def get_local_temp_dir(i: Interface) -> str:
    await afast_wait_explicit(i, MY_APP_CONFIGURATION_COMPLETED_FLAG_NAME)
    app_dir_path: AppDirPath = fast_get_explicit(i, AppDirPath)
    return app_dir_path.cached(fast_get_explicit(i, 'app_temp_dir_path_type'), 
        fast_get_explicit(i, 'app_name_for_fs'))
