Retiring, March 2020 - sorry, you have missed our final public course.
The Coronavirus situation has lead us to suspend public training - which was on the cards anyway, with no plans to resume

Please ask about private 'maintenance' training for Python, Tcl, Perl, PHP, Lua, etc
Happily continuing private consultancy / programming work

# Here are my "controllers"

our @towns = qw(salisbury chippenham trowbridge melksham westbury devizes);

        }

sub inducks {
        my $saying = "<h4>Welcome to life in Wiltshire!</h4><br />";

        # We're starting to build in some logic. However, it's a
        # dog's dinner of controller, business logic [model] and
        # look and feel [view] and we should sort that out soon!

                $saying .= "You could move to ".
                        "<a href=/town/$town.html>".

# Here is my routing - set up and stored with Dancer

# Set up in the form of callbacks (i.e. we give it the address of code
