Writing Maintainable Perl: Clean Code Best Practices

Perl is a powerful and flexible language, but without disciplined practices, codebase maintenance can quickly become a major challenge. This text-based guide teaches you how to write clear, structured, and highly readable Perl code that stands the test of time. You will transition from writing complex, hard-to-debug scripts to crafting clean, modular Perl programs. Through step-by-step written explanations and practical code snippets, you will master the conventions and modern paradigms required to make your code easy to read, test, and extend. What you'll learn: Understand foundational Perl syntax, scoping rules, and safety pragmas to prevent common bugs; Apply modern Perl features, including subroutine signatures and robust error handling patterns; Design modular code using packages and object-oriented principles for maximum reusability; Write clean, self-documenting code using industry-standard style guidelines and formatting; Implement basic unit tests to ensure your Perl applications remain stable during updates. The course starts with essential syntax rules and safety pragmas, establishing a solid foundation before moving into modular design, modern language features, and testing practices. This course is designed for beginner Perl programmers and developers looking to improve their code quality, with no advanced programming experience required.
