# Coding Standard
|
||
|
||
### ✨ **Coding Standards for Snigdha OS Development**
|
||
|
||
To ensure that Snigdha OS maintains a high-quality codebase, it’s essential to follow these coding standards. These guidelines promote readability, maintainability, and collaboration while ensuring the code remains efficient and secure. 🚀
|
||
|
||
|
||
|
||
### 1️⃣ **Consistent Naming Conventions**
|
||
✅ Use meaningful and descriptive names for variables, functions, and classes.
|
||
✅ Stick to a consistent naming convention across the codebase:
|
||
- **camelCase** for variables and functions.
|
||
- **PascalCase** for classes and constructors.
|
||
- **snake_case** for constants and configuration keys.
|
||
|
||
|
||
|
||
### 2️⃣ **Indentation and Formatting**
|
||
✅ Use consistent indentation (2 or 4 spaces preferred). Avoid using tabs.
|
||
✅ Follow a consistent formatting style (e.g., braces alignment, spacing).
|
||
✅ Limit line length to 80-100 characters for better readability.
|
||
✅ Remove unnecessary whitespaces and trailing spaces.
|
||
|
||
|
||
|
||
### 3️⃣ **Comments**
|
||
✅ Add comments to explain complex logic, algorithms, or unusual decisions.
|
||
✅ Keep comments concise, relevant, and synchronized with code changes.
|
||
✅ Avoid obvious comments like `// Incrementing i by 1`.
|
||
|
||
```javascript
|
||
// Good Example:
|
||
function calculateTax(income) {
|
||
// Calculates tax based on progressive slabs.
|
||
...
|
||
}
|
||
```
|
||
|
||
|
||
|
||
### 4️⃣ **Modularity and Code Reusability**
|
||
✅ Break down code into small, reusable functions or modules.
|
||
✅ Group related functionalities into classes or namespaces for better organization.
|
||
|
||
|
||
|
||
### 5️⃣ **Error Handling**
|
||
✅ Use proper error-handling mechanisms like `try-catch` blocks or error codes.
|
||
✅ Avoid exposing internal logic in error messages.
|
||
|
||
```python
|
||
try:
|
||
result = perform_operation()
|
||
except ValueError as e:
|
||
print("Invalid input. Please try again.") # Avoid exposing "ValueError: details"
|
||
```
|
||
|
||
|
||
|
||
### 6️⃣ **Code Readability**
|
||
✅ Write simple and clear code. Avoid unnecessary complexity.
|
||
✅ Use descriptive variable and function names instead of single-letter identifiers.
|
||
✅ Favor clarity over cleverness.
|
||
|
||
|
||
|
||
### 7️⃣ **Consistent Code Style**
|
||
✅ Follow the style guide for the programming language used (e.g., PEP 8 for Python, ESLint for JavaScript).
|
||
✅ Adopt consistent practices for spacing, indentation, and braces placement.
|
||
|
||
|
||
|
||
### 8️⃣ **Documentation**
|
||
✅ Document every function, class, and module with clear descriptions.
|
||
✅ Include parameter details, return values, and potential exceptions in documentation.
|
||
|
||
```python
|
||
def calculate_area(radius):
|
||
"""
|
||
Calculates the area of a circle.
|
||
|
||
Args:
|
||
radius (float): The radius of the circle.
|
||
|
||
Returns:
|
||
float: The area of the circle.
|
||
"""
|
||
return 3.14 * radius ** 2
|
||
```
|
||
|
||
|
||
|
||
### 9️⃣ **Testing**
|
||
✅ Write unit tests for all critical functionality.
|
||
✅ Aim for at least 80% code coverage.
|
||
✅ Automate tests where possible with frameworks like `pytest`, `Jest`, or `JUnit`.
|
||
|
||
|
||
|
||
### 🔟 **Version Control**
|
||
✅ Use Git for version control. Follow branching strategies like **Git Flow**.
|
||
✅ Write clear, descriptive commit messages in the [Conventional Commits](https://www.conventionalcommits.org) format:
|
||
|
||
```
|
||
feat: add feature for user authentication
|
||
fix: resolve bug in payment gateway integration
|
||
docs: update README with installation steps
|
||
```
|
||
|
||
|
||
|
||
### 1️⃣1️⃣ **Performance Considerations**
|
||
✅ Write efficient algorithms with optimal time and space complexity.
|
||
✅ Avoid unnecessary loops, nested loops, or redundant operations.
|
||
✅ Use lazy loading or caching for heavy computations or data fetching.
|
||
|
||
|
||
|
||
### 1️⃣2️⃣ **Security**
|
||
✅ Sanitize and validate all user inputs.
|
||
✅ Use parameterized queries for database operations to avoid SQL injection.
|
||
✅ Regularly audit code for vulnerabilities like XSS, CSRF, or buffer overflows.
|
||
|
||
|
||
|
||
### 1️⃣3️⃣ **Dependencies and Third-party Libraries**
|
||
✅ Use only necessary and trusted libraries.
|
||
✅ Keep dependencies updated to ensure compatibility and fix vulnerabilities.
|
||
|
||
|
||
|
||
### 1️⃣4️⃣ **Internationalization (i18n) and Localization (l10n)**
|
||
✅ Design code to support multiple languages and locales.
|
||
✅ Externalize strings into resource files for easy translation.
|
||
|
||
|
||
|
||
### 1️⃣5️⃣ **Accessibility**
|
||
✅ Ensure UI components follow accessibility standards (e.g., WCAG).
|
||
✅ Provide alternative text for images and ensure keyboard navigation.
|
||
|
||
|
||
|
||
### 1️⃣6️⃣ **Concurrency and Thread Safety**
|
||
✅ For concurrent operations, write thread-safe code to avoid race conditions.
|
||
✅ Use synchronization mechanisms like locks or semaphores.
|
||
|
||
|
||
|
||
### 🔑 **Key Principles**
|
||
1️⃣ **Readability**: Write code as if the next person maintaining it is you in six months.
|
||
2️⃣ **Modularity**: Make changes easier by keeping code decoupled and modular.
|
||
3️⃣ **Consistency**: Adopt a uniform style to avoid confusion and ensure maintainability.
|
||
|
||
Following these standards will not only improve code quality but also foster a collaborative and professional environment. Happy coding! 🎉👩💻👨💻 |
