Programming Perl - for newcomers to the language
This course introduces you to the Perl programming language.
Early sections of the course, tell you
how variables, calculations, conditionals, assignments, etc. work in
Perl. The course carries on an you'll be learning
about lists, modules, hashes, regular expressions and many other
core Perl topics which don't have equivalents in other languages.
The final sections of the course cover more complex data handling,
using standard and CPAN modules, and a look forward.
There are many practical exercises set during the course, and
you'll find yourself writing useful short applications, both
keyboard-to-screen and web-based. We encourage you to bring your
own data along to use during these sessions.
This course covers version 5 of Perl (the current version), with footnotes
where appropriate to tell you about Perl 6. Our plans for
Perl 6 training
are described on a separate page.
Note - this course is now combined with Learning to program in Perl. We are able to
offer the combined public course more frequently, and most trainees
benefit from the slightly slower pace and additional practicals.
Practical experience in programming in another
computer language, such as C, C++, Java, Shell, Tcl, etc. is an
advantage, but is not mandatory.
Getting the most from your Well House Consultants course
Perl is a very widely used programming language indeed, but it's
name isn't well know outside the programming community as it's an open
source language that lack the marketing "hype" - it's just a superb
technical tool in a very wide variety of applications. It's name - PERL -
stands for the "Practical Extraction and Reporting language" which is
a pretty good sound-bite to tell you what it does.
A new release
of Perl - Perl 6 - has been undergoing development for a considerable time.
Our course covers Perl 5, and will continue to do so while it is dominant,
but also includes a short look ahead to Perl 6 so that new code developers
will be able to take advantage of it once it's available to them.
