Coding Guidelines

General Principles

• Code Style: Follow consistent and readable code conventions for your language.
• Documentation: All code must include proper documentation (see language-specific guidelines below).
• Tests: Run existing tests and add tests for new features where applicable.
• Naming Conventions: Use descriptive, meaningful names for variables, functions, and classes.
• DRY Principle: Don't Repeat Yourself - avoid code duplication.
• KISS Principle: Keep It Simple, Stupid - favor simplicity over complexity.

Language-Specific Guidelines

Python

• Style Guide: Follow PEP 8 style guide.
• Docstrings: Use triple-quoted docstrings for all functions, classes, and modules.

  def function_name(param1: str, param2: int) -> bool:
      """
      Brief description of what the function does.
      
      Args:
          param1 (str): Description of param1
          param2 (int): Description of param2
      
      Returns:
          bool: Description of return value
      
      Raises:
          ValueError: When param2 is negative
      
      Example:
          >>> function_name("test", 5)
          True
      """
      pass

• Type Hints: Use type hints for function parameters and return values.
• Naming: Use snake_case for functions and variables, PascalCase for classes.

Java

• Style Guide: Follow Google Java Style Guide.
• JavaDoc: Use JavaDoc comments for all public classes and methods.

  /**
   * Brief description of what the class/method does.
   * 
   * @param param1 Description of param1
   * @param param2 Description of param2
   * @return Description of return value
   * @throws IllegalArgumentException When param2 is negative
   * 
   * @example
   * <pre>
   * MyClass obj = new MyClass();
   * boolean result = obj.methodName("test", 5);
   * </pre>
   */
  public boolean methodName(String param1, int param2) {
      // implementation
  }

• Naming: Use camelCase for methods and variables, PascalCase for classes.
• Constants: Use UPPER_SNAKE_CASE for constants.

JavaScript/TypeScript

• Style Guide: Follow Airbnb JavaScript Style Guide.
• JSDoc: Use JSDoc comments for all functions.

  /**
   * Brief description of what the function does.
   * 
   * @param {string} param1 - Description of param1
   * @param {number} param2 - Description of param2
   * @returns {boolean} Description of return value
   * @throws {TypeError} When param2 is not a number
   * 
   * @example
   * const result = functionName('test', 5);
   * console.log(result); // true
   */
  function functionName(param1, param2) {
      // implementation
  }

• Naming: Use camelCase for functions and variables, PascalCase for classes.
• Modern Syntax: Prefer const/let over var, use arrow functions where appropriate.

C/C++

• Style Guide: Follow Google C++ Style Guide.
• Doxygen Comments: Use Doxygen-style comments for functions and classes.

  /**
   * @brief Brief description of what the function does.
   * 
   * @param param1 Description of param1
   * @param param2 Description of param2
   * @return Description of return value
   * 
   * @note Any important notes about the function
   * 
   * @example
   * @code
   * int result = functionName(5, 10);
   * printf("%d", result);
   * @endcode
   */
  int functionName(int param1, int param2) {
      // implementation
  }

• Naming: Use snake_case for functions and variables (C) or camelCase (C++).
• Memory Management: Always free allocated memory, check for NULL pointers.

   • All parameters explained
   • Return value described
   • Exceptions/errors documented
   • At least one usage example

3. Inline Comments:

Quick Reference

All code must include:

• ✅ File-level documentation explaining purpose
• ✅ Function/method documentation with parameters and return values
• ✅ At least one working usage example
• ✅ Inline comments for complex logic
• ✅ Updated README in the relevant language directory

Detailed Documentation Guide

For comprehensive documentation standards, examples, and best practices, see:

📚 DOCUMENTATION_GUIDE.md - Complete guide with examples for all languages

Language-Specific Standards

• Python: Python/README.md - PEP 257 docstring standards
• Java: Java/README.md - JavaDoc guidelines
• JavaScript: Javascript/README.md - JSDoc standards
• C: C/README.md - Doxygen standards
• C++: C++/README.md - Doxygen standards for C++

Documentation Template Example

Here's a quick template for documenting a function (language-specific formats in the guide):

├── Brief one-line description
├── Detailed explanation (if needed)
├── Parameters with types and descriptions
├── Return value with type and description
├── Exceptions/errors that may be raised
├── At least one usage example
└── Notes about edge cases or performance

Before Submitting Your PR

Use this checklist to ensure your documentation meets standards:

• All functions have complete documentation
• Parameters and return types are documented

• Complex algorithms are explained
• Edge cases and limitations are noted
• Language-specific format is followed (JavaDoc, JSDoc, etc.)
• README in language directory is updated

Getting Help with Documentation

If you're unsure about documentation:

1. Check DOCUMENTATION_GUIDE.md for examples
2. Look at well-documented files in the repository
3. Use GitHub Copilot to generate documentation templates
4. Ask maintainers in your PR for guidance

Remember: Good documentation is as important as good code! 📚

Code Review Process

1. Pull requests will be reviewed by the maintainers. Be prepared to make revisions based on feedback.
2. Once approved, your code will be merged into the main branch.
3. If your contribution adds substantial changes, ensure that they are well-tested and documented.

Using GitHub Copilot for Code Review

GitHub Copilot can assist in the code review process:

1. Before Submitting:

   • Use Copilot to generate documentation for undocumented functions
   • Ask Copilot to review your code for potential issues
   • Request suggestions for improving code readability

2. Configuring Copilot for Code Review:

   • Enable GitHub Copilot code review features
   • Set up custom instructions for your coding standards
   • Use Copilot Chat to explain complex code sections

3. Best Practices:

   • Review Copilot suggestions carefully before accepting
   • Use Copilot to generate test cases
   • Ask Copilot to identify potential bugs or security issues
