Beginner
PERL is a programming language (♦ see DEF) multiplatform, created in 1987.
PERL essentially allows you to conceive processing programs.
Code Examples
Let's start with very simple codes. The more you progress, page after page, the more sophisticated the scripts will be. However, you must pass the cape of 30 to 40 pages per level, before moving on to the next step... COPY AND IMMERSE YOURSELF!
C 0001 - Hello World !
Say hello...
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
use strict;
=comment
while(my $ex1 = ) {
print $ex1;
}
=cut
print 'Hello World !'
Reproduce this code, choosing one of the compilers below (♦ see DEF) (don't copy-paste! It would be too easy). They have the same function, just pick up one according to your preferences.
When you copy your code, replace the existing code (by default) with your own.
Warning ! For some of these compilers, you might have to choose the programming language yourself, in a specific menu which is offered to you. Of course, don't forget to click on RUN !
C 0002 - Variables
Getting a result...
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
$a = 88; $b = 'Résultat:'; print "$b", $a * $a;
Reproduce this code, choosing one of the compilers below (♦ see DEF) (don't copy-paste! It would be too easy). They have the same function, just pick up one according to your preferences.

C 0003 - List
Showing names...

%a = (
Joseph => ' Mariani',
Julie => ' Hollande',
Christian => ' Turquoise'
);
print $a{Julie};
print $a{Christian};

C 0004 - Showing a variable
Showing a day...
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
Reproduce this code (please do not copy-paste!). Watch out for the indentation !
@a = ('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday');
print $a[2];
my @b = @a[2, 4]; # @b = ( 'Wednesday', 'Saturday' )
my @c = @a[2..4]; # @c = ( 'Wednesday', 'Tuesday', 'Friday' )
