Usage examples

• Check for OS

  from vt.utils.commons.commons.os import is_windows
  
  windows = is_windows()
  

  Check in vt.utils.commons.commons.os and documentation for more functions and utilities related to OS.

• Perform some operation on a root directory

  from vt.utils.commons.commons.op import RootDirOp, CWDRootDirOp, RootDirOps
  from pathlib import Path
  
  class MyRootDirectoryOperation(RootDirOp):
    ...
    @property
    def root_dir(self)-> Path:
        return Path('path', 'to', 'my', 'root-directory')
  
  certain_root_dir_operation: CWDRootDirOp = RootDirOps.from_path(Path('path', 'to', 'my', 'root-directory'))
  

  Check in vt.utils.commons.commons.op and documentation for more functions and utilities related to operations.

• Perform state operations

  from vt.utils.commons.commons.state import DoneMarker
  
  # Track state by marking done
  class MyStateManager(DoneMarker[int]):
    def __init__(self, *args, **kwargs):
        self.id_state = {1: False}
        ...
  
    def mark_done(self, _id: int)-> bool:
        # mark done for _id
        if self.id_state[_id] is True:
            return False
        self.id_state[_id] = True
        return True
  

  Check in vt.utils.commons.commons.state and documentation for more functions and utilities related to tracking state.

• Check if a value is MISSING

  from vt.utils.commons.commons.core_py import MISSING, Missing, is_missing
  
  def some_operation(arg: Missing = MISSING):
    """
    ``MISSING`` can be used as a default value sentinel when ``None`` is a valid value for arg.
    """
    arg = 10 if is_missing(arg) else arg
    ...
  

  Check in vt.utils.commons.commons.core_py and documentation for more functions and utilities related to function management.

• Query and operate on iterables

  >>> from vt.utils.commons.commons.collections import get_first_true, get_first_non_none
  
  >>> assert 3 == get_first_true([1, 3, 5, 7, 2, 1], 8, lambda x: x>2)
  >>> assert 10 == get_first_non_none([None, None, 10, 2, 6], 9)
  

  Check in vt.utils.commons.commons.collections and documentation for more functions and utilities related to collection management.
