Coding⚑

Python⚑

Dash⚑

• New: Test programs that use sh.

  sh can be patched in your tests the typical way, with unittest.mock.patch():

  from unittest.mock import patch
  import sh
  
  def get_something():
      return sh.pwd()
  
  @patch("sh.pwd", create=True)
  def test_something(pwd):
      pwd.return_value = "/"
      assert get_something() == "/"
  

Python Snippets⚑

• New: Change the logging level of a library.

  sh_logger = logging.getLogger("sh")
  sh_logger.setLevel(logging.WARN)
  

• New: Get all subdirectories of a directory.

  [x[0] for x in os.walk(directory)]
  

• New: Move a file.

  import os
  
  os.rename("path/to/current/file.foo", "path/to/new/destination/for/file.foo")
  

• New: Copy a file.

  import shutil
  
  shutil.copyfile(src_file, dest_file)
  

questionary⚑

• New: Conditionally skip questions.

  Sometimes it is helpful to be able to skip a question based on a condition. To avoid the need for an if around the question, you can pass the condition when you create the question:

  import questionary
  
  DISABLED = True
  response = questionary.confirm("Are you amazed?").skip_if(DISABLED, default=True).ask()
  

• New: Don't highlight the selected option by default.

  If you don't want to highlight the default choice in the select question use the next style:

  from questionary import Style
  
  choice = select(
      "Question title: ",
      choices=['a', 'b', 'c'],
      default='a',
      style=Style([("selected", "noreverse")]),
  ).ask()
  

SQLite⚑

• New: Get the columns of a database.

  sqlite PRAGMA table_info(table_name);
