Course 581:
Advanced Perl Programming

(3 days)

 

Course Description

This is an advanced Perl programming course aimed at the Perl programmer who needs to build programming tools. The course starts with an advanced review of Perl and then shows TDD techniques, assertions, and the Perl Debugger. Perl has the most extensive regular expression engine in all programming languages. The second chapter reviews and shows all the regular expression techniques to include string replacement. With the basic development tools covered, the course continues with a complete exploration of how to build and distribute Perl packages. How to use packages is explored while learning about networking and database access. Good programming handles exceptions and interrupts, and the course covers them both. The course ends by covering a series of small topics any programmer should know how to do.
