Become familiar with the Perl object model.
- [Voiceover] Strictly speaking Perl doesn't have…an object model per se,…in Perl an object is simply reference…a class is a pack and a method is a function.…Here's a working copy of hello.pl…from Chapter 14 of the exercise files,…all that said, the object model in Perl…actually does work remarkably well.…Let's go ahead and we'll start here…by importing a module, I'm going to say…use BW::Simple;…and so that imports the…module Simple from the BW directory or folder.…
Now, in Perl, a module, I'm gonna go here and open this up…the name of a module is its directory path…from the beginning of the import directory…and in this case Perl is set up to…import from it's current directory…and so as usual you use by default and so…it finds this BW folder and then under that…it finds this Simple.pm.…Modules are named with .pm rather than….pl for Perl scripts.…And so this module is actually BW::Simple…and it's actually really recommended…it's good practice in Perl to name your modules…under a directory, to put them under a directory…
Watch to learn the details of the Perl syntax, from variables, conditionals, loops, and data structures to regular expressions, functions, and references. A quick-start guide is included for experienced developers who want to get up and running with Perl 5 fast, and the entire course is recommended for both new and experienced programmers alike. Later chapters cover file handling and reusing code with Perl modules, plus Perl best coding practices.
