49th Week of 2021

Life Management⚑

Music Management⚑

• New: Introduce how I manage my music library.

MusicBrainz⚑

• New: How to contribute to MusicBrainz.

  MusicBrainz is an open music encyclopedia that collects music metadata and makes it available to the public.

  MusicBrainz aims to be:

  • The ultimate source of music information by allowing anyone to contribute and releasing the data under open licenses.
  • The universal lingua franca for music by providing a reliable and unambiguous form of music identification, enabling both people and machines to have meaningful conversations about music.

  Like Wikipedia, MusicBrainz is maintained by a global community of users and we want everyone — including you — to participate and contribute.

Coding⚑

Python⚑

GitPython⚑

• New: Clone a repository.

  from git import Repo
  
  Repo.clone_from(git_url, repo_dir)
  

• New: Create a branch.

  new_branch = repo.create_head('new_branch')
  assert repo.active_branch != new_branch # It's not checked out yet
  repo.head.reference = new_branch
  assert not repo.head.is_detached
  

• New: Get the latest commit of a repository.

  repo.head.object.hexsha
  

Python Snippets⚑

• New: Capture the stdout of a function.

  import io
  from contextlib import redirect_stdout
  
  f = io.StringIO()
  with redirect_stdout(f):
      do_something(my_object)
  out = f.getvalue()
  

• New: Make temporal directory.

  import tempfile
  
  dirpath = tempfile.mkdtemp()
  

• New: Change the working directory of a test.

  import unittest
  import os
  
  from src.main import get_cwd
  
  class TestMain(unittest.TestCase):
  
      def test_get_cwd(self):
          os.chdir('src')
          print('testing get_cwd()')
          current_dir = get_cwd()
          self.assertIsNotNone(current_dir)
          self.assertEqual(current_dir, 'src')
  

• New: Copy a directory.

  import shutil
  
  shutil.copytree('bar', 'foo')
  

• Correction: Use fixture to change the working directory of a test.

  The previous code didn't work, instead use the next fixture:

  @pytest.fixture(name="change_test_dir")
  def change_test_dir_(request: SubRequest) -> Any:
      os.chdir(request.fspath.dirname)
      yield
      os.chdir(request.config.invocation_dir)
  

Poetry⚑

• New: Debugging why a package is not updated to the latest version.
• New: Checking what package is using a dependency.
• New: Try to use pass as a keyring backend to store the PYPI token.

DevOps⚑

Continuous Integration⚑

Dependency managers⚑

• Correction: Deprecate in favour of Poetry.

Automating Processes⚑
