Welcome to Perl Programming, an educational app designed to help you learn Perl scripting, text processing, regular expressions, file handling, system automation, database connectivity, and backend development. It offers organized lessons and practical guides for students, developers, system administrators, DevOps learners.

📱 DUAL-HUB LEARNING STRUCTURE
1. LEARN TAB
Explore Perl fundamentals, syntax, data types, arrays, hashes, regular expressions, control flow, subroutines, file operations, modules, database integration, web scripting, and object-oriented programming.

2. HOW-TO TAB
Follow step-by-step guides on installing Perl, running scripts, processing text, parsing files, handling command-line arguments, debugging, testing, and deployment.

📚 PERL PROGRAMMING TOPICS
• Getting Started with Perl
Understand what Perl is, where it is used, how to install it, configure a development environment, and run your first script.

• Variables and Data Types
Learn about scalars, numbers, strings, undefined values, operators, expressions, interpolation, and basic Perl syntax.

• Arrays, Hashes, and References
Work with arrays, hashes, lists, references, and nested structures to store, organize, and access information.

• Strings and Regular Expressions
Study string operations, splitting, joining, pattern matching, substitutions, captures, and regular expressions for search, validation, and text transformation.

• Conditions and Loops
Understand if, unless, while, until, for, foreach, loop labels, and control statements used to manage program flow.

• Subroutines and Scope
Create reusable functions, pass arguments, return values, and manage variable scope with my, local, and state.

• Files, Directories, and Input/Output
Learn to open, read, write, append, and close files. Explore filehandles, directories, standard input, standard output, and formatted text.

• Modules and CPAN
Understand Perl packages, modules, namespaces, CPAN installation, reusable libraries, and coding conventions.

• Database and Web Integration
Learn how Perl works with databases through DBI, how CGI scripts support web applications, and how scripts can handle email, processes, and system tasks.

• Object-Oriented Perl
Study packages, classes, objects, methods, constructors, inheritance, and structured application design.

💻 PRACTICAL HOW-TO GUIDES
The How-To section includes guidance on:
• Installing Perl on Windows, macOS, and Linux
• Running scripts from the terminal
• Working with scalars, arrays, and hashes
• Reading input through STDIN
• Manipulating strings and regular expressions
• Creating reusable subroutines
• Handling errors with eval, die, and warn
• Reading and writing text files
• Processing arguments with @ARGV
• Parsing CSV, JSON, and XML data
• Connecting scripts to databases
• Executing system commands
• Debugging with the Perl debugger
• Writing unit tests with Test::More
• Organizing modules and packages
• Preparing scripts for deployment

🎯 WHO CAN USE THIS APP?
This app is suitable for computer science students, programming beginners, system administrators, DevOps engineers, backend developers, web developers, data engineers, automation learners, and professionals who work with scripts, logs, files, or structured data.

💡 LEARNING BENEFITS
Structured chapters make it easier to study Perl syntax, revise programming concepts, understand regular expressions, and connect theory with scripting tasks. Search helps users locate topics quickly, while bookmarks make it easier to save useful lessons.

The content can support academic study, interview preparation, system automation, backend development, log processing, and general programming skill development.

🔄 REGULAR EDUCATIONAL UPDATES
The app receives general updates related to Perl lessons, scripting guides, content organization, search and bookmark usability, performance, bug fixes, and stability. Updates may also refine existing explanations and improve the learning experience.
