Common

This module contains tools for general use.

Attribute Manager

This class contains methods for managing class attributes taking in consideration real mangled name of each attribute.

• examples:

  from tools.common import AttributeManager
  
  class SomeClass:
      __slots__ = ('__private_attr', '_protected_attr', 'public_attr')
      ...
      def as_static(self, attr_name: str):
          mangled_name = AttributeManager.get_name(obj=self, attr=attr_name)
          print(f'attribute_mangled_name: {mangled_name}')
          #
          found = AttributeManager.has_attribute(obj=self, attr=attr_name)
          print(f'found: {found}')
          #
          if not found:
              AttributeManager.set_attribute(obj=self, attr=attr_name, value=None)
          #
          value = AttributeManager.get_attribute(obj=self, attr=attr_name)
          print(f'value: {value}')
          pass
          
      def as_instance(self, attr_name: str):
          attr = AttributeManager(obj=self, attr=attr_name)
          #
          mangled_name = attr.name
          print(f'attribute_mangled_name: {mangled_name}')
          #
          found = attr.exists
          print(f'found: {found}')
          #
          if not found:
              attr.value = None
          #
          value = attr.value
          print(f'value: {value}')
          pass
      ...
  pass
  

Hide Big Content

This method tries to hide big content over a limit of characters.

• examples:

  from tools.common import hide_big_content
  
  content = {
      'key': 'value',
      'l': [1, 'a', 'b'],
      's': 'aaa',
      't': (1, 2, 'a' * 5000)
  }
  print(f'content: {content}')
  processed = hide_big_content(value=content)
  print(f'processed: {processed}')
  

Mask password

This method tries to mask passwords from provided object.

• examples:

  from tools.common import mask_password
  
  content = [
      1, 2, True,
      {
          'password': '12345',
          'pwd': 'x56',
          'pwd_lst': ['123', '345', '567']
      }
  ]
  print(f'content: {content}')
  processed = mask_password(value=content)
  print(f'processed: {processed}')
  

Get Location

Try to resolve file / method location. Can be used for template relative location

• examples:

  from tools.common import get_location
  
  def func(): pass
  
  func_location = get_location(func=func)
  print(f'func_location: {func_location}')
  
  file_location = get_location(file=__file__)
  print(f'file_location: {file_location}')
  

Folders

This module was created to manage main folder operations.

• examples:

  from tools.folders import Folder
  
  path = 'path/to/folder'
  
  if not Folder.exists(path=path):
      Folder.create(path='path/to/old-folder', recursive=True)
      
  Folder.remove(path='path/to/new-folder', recursive=True)
  

Files

This module was created to perform main file operations.

• examples:

  from tools.files import File
  
  path = 'path/to/file'
  name = 'file-name.ext'
  
  if not File.exists(path=path, name=name):
      File.write(path=path, name=name, content=None)
  
  demo = File.read(path=path, name=name)
  print(f'Demo file: {demo}')
  
  locked = File.lock(path=path, name=name)
  print('File is locked')
  
  try:
      File.write(path=path, name=name, content=b'new-content')
  except Exception as exc:
      print(f'Something got wrong: {exc}')
  
  File.unlock(file=locked)
  print('File is free to use')
  
  File.remove(path=path, name=name)
  

Tables

This module was created to store data as a table, with data / column validation and filtering. Cells can be accessed by index or by key.

• examples:

  from tools.tables import Table
  
  table = Table(
      table={
          'columns': ['col-1', 'col-2'],
          'data': [
              # row-1
              {'col-1': 1, 'col-2': 2},
              # row-2
              {'col-1': True, 'col-2': 'str'}
          ]
      }
  )
  print(f'table: {table}')
  
  filtered_1 = table.filter(exclude=('col-1',))
  print(f'filtered_1: {filtered_1}')
  
  filtered_2 = table.filter(include=('col-2',))
  print(f'filtered_2: {filtered_2}')
