Duncan White's Perl 2011 Course Materials

Perl Short Course: December 2011

dcw@doc.ic.ac.uk
This web page contains all the materials for my Perl Short Course, that I've just given this week (12th-16th December 2011) to Dept of Computing second year students.
Changes this year:

Lovely Ann Arbor colourful Latex Beamer format, wow! the Perl course enters the 21st century; only 11 years late:-)

'my' variables from day one. (I also thought about using 'use strict' from day one: decided not to!)

used 'IO::File()' instead of 'open()'.

Creating modules part of lecture 6 replaced completely with new `maxfreq' example.

Here are the course materials, covering the lectures as I gave them:

First Session

Here are the Postscript full size slides for the first session.

Here are the PDF full size slides for the first session.

Here are the Postscript 4-up lecture notes for the first session.

Here are the PDF 4-up lecture notes for the first session.

And here are the examples for the first session, as a gzipped tar file that will create a directory called lect1-examples.

Example CGI Scripts from the Fifth Session

Here is eg1.cgi: a first trivial example.

Here is eg2.cgi: first example using CGI.

Here is eg3.cgi: a silly form.

Sixth Session

Please note that lecture 6 as printed did not contain maxfreq::forget() in eg1, immediately above the call to maxfreq::remember(); the notes below do!
Also, I realise there's an unanswered question in the slides - at the bottom of page 15/28, in the discussion of why printperson($person) isn't a method, it asks "how hard is converting a normal subroutine to a method?".
The answer is: incredibly easy in this case: printperson takes a person as it's first (only) argument. This is exactly like the object method calling convention, so it's very nearly a method already! Move printperson from eg1 to Person.pm and rename it print. Optionally rename it's $person argument as $self. Back in eg1, change all printperson($person) calls to $person->print.
In the examples tarball below, code after the above modifications will be found in the person-v2/ directory.
