Perl Development Topics
This section aims to cover various topics that one is likely to encounter when doing Perl development. They are mostly common to the particular task one is trying to achieve with Perl and its domain.
Date and Time Handling
Handling Dates and Times (parsing, formatting, manipulating, etc.) in Perl.
Debugging Perl Programs
When bugs occur, learn how to find their cause and correct them effectively.
Files and Directories Handling
How to handle files and directories in Perl.
Hashes
Hashes (also known as “associative arrays”, “maps”, or “dictionaries”) are one of Perl’s three fundamental data structures, and its least understood one. This page gives some resources for learning about hashes.
Modules and Packages
Encapsulate code in reusable units, and make sure symbols live in their own namespaces. The precursor for Object-Oriented Programming.
References
References allow the programmer to store an aggregate data structure in a simple variable, which can be passed around more easily, to represent complex, nested data structures, and also serve as the basis of Perl's object system.
Regular Expressions
Regular expressions enable one to match simple or complex patterns in text , extract them, and process them.
Object-Oriented Programming (OOP) in Perl
Learn about how to write classes, objects, and other concepts of Object-Oriented Programming in Perl.
Optimising and Profiling
How to make your Perl programs run faster.
Scoping and Variables in Perl
Scoping is Perl's way of making sure variables are localised and don't interfere with variables of the same name in different places (or alternatively, are not confused with different variables of similar names).
Using CPAN with Perl
CPAN is the Comprehensive Perl Archive Network, which contains a wealth of open-source and reusable source code, that can be used in your applications. Follow the link to learn how to effectively use CPAN.
