Contributing guidelines

Before contributing

Welcome to Anomstack! Before submitting your pull requests, please ensure that you read the whole guidelines. If you have any doubts about the contributing guide, please feel free to state it clearly in an issue.

Contributing

Contributor

We are delighted that you are considering contributing to Anomstack! By being one of our contributors, you agree and confirm that:

• You did your work - no plagiarism allowed.
  • Any plagiarized work will not be merged.
• Your work will be distributed under MIT License once your pull request is merged.
• Your submitted work fulfills or mostly fulfills our styles and standards.

New implementation is welcome!

Improving comments and writing proper tests are also highly welcome.

Contribution

We appreciate any contribution, from fixing a grammar mistake in a comment to implementing complex features. Please read this section if you are contributing your work.

Issues

If you are interested in resolving an open issue, simply make a pull request with your proposed fix.

Do not create an issue to contribute a feature. Please submit a pull request instead.

Please help us keep our issue list small by adding Fixes #{$ISSUE_NUMBER} to the description of pull requests that resolve open issues. For example, if your pull request fixes issue #10, then please add the following to its description:

Fixes #10

GitHub will use this tag to auto-close the issue if and when the PR is merged.

Pre-commit plugin

Use pre-commit to automatically format your code to match our coding style:

python3 -m pip install pre-commit  # only required the first time
pre-commit install

That's it! The plugin will run every time you commit any changes. If there are any errors found during the run, fix them and commit those changes. You can even run the plugin manually on all files:

pre-commit run --all-files --show-diff-on-failure

Coding Style

We want your work to be readable by others; therefore, we encourage you to note the following:

• Please write in Python 3.12+. For instance: print() is a function in Python 3 so print "Hello" will not work but print("Hello") will.

• Please focus hard on the naming of functions, classes, and variables. Help your reader by using descriptive names that can help you to remove redundant comments.

  • Single letter variable names are old school so please avoid them unless their life only spans a few lines.
  • Expand acronyms because gcd() is hard to understand but greatest_common_divisor() is not.
  • Please follow the Python Naming Conventions so variable_names and function_names should be lower_case, CONSTANTS in UPPERCASE, ClassNames should be CamelCase, etc.

• We encourage the use of Python f-strings where they make the code easier to read.

• All submissions will need to pass the test ruff . before they will be accepted so if possible, try this test locally on your Python file(s) before submitting your pull request.

  python3 -m pip install ruff  # only required the first time
  ruff .

• Original code submission require docstrings or comments to describe your work.

• More on docstrings and comments:

  If you used a Wikipedia article or some other source material to create your algorithm, please add the URL in a docstring or comment to help your reader.

  The following are considered to be bad and may be requested to be improved:

  x = x + 2	# increased by 2

  This is too trivial. Comments are expected to be explanatory. For comments, you can write them above, on or below a line of code, as long as you are consistent within the same piece of code.

  We encourage you to put docstrings inside your functions but please pay attention to the indentation of docstrings. The following is a good example:

  def sum_ab(a, b):
      """
      Return the sum of two integers a and b.
      """
      return a + b

• Write tests (especially doctests) to illustrate and verify your work. We highly encourage the use of doctests on all functions.

  def sum_ab(a, b):
      """
      Return the sum of two integers a and b
      >>> sum_ab(2, 2)
      4
      >>> sum_ab(-2, 3)
      1
      >>> sum_ab(4.9, 5.1)
      10.0
      """
      return a + b

  These doctests will be run by pytest as part of our automated testing so please try to run your doctests locally and make sure that they are found and pass:

  python3 -m doctest -v my_submission.py

  The use of the Python built-in input() function is not encouraged:

  input('Enter your input:')
  # Or even worse...
  input = eval(input("Enter your input: "))

  However, if your code uses input() then we encourage you to gracefully deal with leading and trailing whitespace in user input by adding .strip() as in:

  starting_value = int(input("Please enter a starting value: ").strip())

  The use of Python type hints is encouraged for function parameters and return values.

  def sum_ab(a: int, b: int) -> int:
      return a + b

• List comprehensions and generators are preferred over the use of lambda, map, filter, reduce but the important thing is to demonstrate the power of Python in code that is easy to read and maintain.

• Avoid importing external libraries for basic algorithms. Only use those libraries for complicated algorithms.

• If you need a third-party module that is not in the file requirements.txt, please add it to that file as part of your submission.

Other Requirements for Submissions

• The file extension for code files should be .py.

• Strictly use snake_case (underscore_separated) in your file_name, as it will be easy to parse in future using scripts.

• If possible, follow the standard within the folder you are submitting to.

• If you have modified/added code work, make sure the code compiles before submitting.

• If you have modified/added documentation work, ensure your language is concise and contains no grammar errors.

• Most importantly,

  • Be consistent in the use of these guidelines when submitting.
  • Happy coding!
