Perl 5 & 6


P5 & P6


@cities = 'roma', 'milano', 'torino';

Klammern Gruppieren !


@cities = 'roma', 'milano', 'torino';

Itemkontext

$cities = ('roma', 'milano', 'torino');

$cities = 'roma', 'milano', 'torino';

Itemkontext

# Parcel()$cities = ('roma', 'milano', 'torino');# Str()$cities = 'roma', 'milano', 'torino';

Was Ist Str ?

# Parcel()$cities = ('roma', 'milano', 'torino');# Str() - 'roma' ist ein String$cities = 'roma', 'milano', 'torino';

Nur Der Erste Wert

# Parcel()$cities = ('roma', 'milano', 'turino');# $a, $b, $c = 1, 2, 3;$cities = 'roma', 'milano', 'torino';

Was Ist Ein Parcel ?

# Parcel Sequenz von Items$cities = ('roma', 'milano', 'torino');# Str()$cities = 'roma', 'milano', 'torino';

() Erinnert An Was?

# Parcel wie in function(1,2,3);$cities = ('roma', 'milano', 'torino');# Str()$cities = 'roma', 'milano', 'torino';

Parcel

Array() ne List() ne Parcel()

# List()$cities = @('roma', 'milano', 'torino');# Parcel()$cities = ('roma', 'milano', 'torino');

Nur Eine Liste

# List()$cities = list('roma', 'milano', 'torino');# Parcel()$cities = ('roma', 'milano', 'torino');

Pos. Param. Als Liste

# List()$cities = list('roma', 'milano', 'torino');# List()$cities = ||('roma', 'milano','torino');

Array Objekt

$cities = ['roma', 'milano', 'torino'];@cities = 'roma', 'milano', 'torino';

Nummer An Elementen

say length @cities; # 3

say elems @cities; # 3 # kein length

elems Ist Methode

say length @cities; # 3

say @cities.elems; # 3

An Jedem Arrayobjekt

say scalar @$cities; # 3

say $cities.elems; # 3

Inhalt Vom Skalar

say @$cities; # roma ...

say $cities; # roma ...

Auch Im Skalarkontext

say @cities; # roma ...

say $(@cities); # roma ...

Ich Meinte Itemkontext

say @cities; # roma ...

say item(@cities); # roma ...

Numerischer Kontext

say scalar @cities; # 3

say + @cities; # 3

Numerischer Kontext

say scalar @$cities; # 3

say + $cities; # 3

Boolkontext

say values @cities; # romami...

say ? @cities; # Bool::True

Stringkontext

say @cities; # roma milano

say ~ @cities; # roma milano ...

. Wurde ~


say ... ~ @cities; # ...roma mila..

Gehts Auch in P6 ?

say @cities;# roma milano torino

say @cities;# roma milano torino?

Nicht Ganz

say @cities; # roma milano ...

say @cities; # @cities

Fge [] An


say @cities[];# roma milano ...

Das War Kein Spezialfall


say @cities[]; # roma milano ...

Perl 5 & 6
