NAME
MFor - A module for multi-dimension looping.
SYNOPSIS
use MFor;
mfor {
my @args = @_; # get a,x,1 in first loop
print "Looping.. " , join(',',@_) , "\n";
} [
[ qw/a b c/ ],
[ qw/x y z/ ],
[ 1 .. 7 ],
];
or
MFor->it( 1 .. 7 )->it( 'a' ... 'z' )->do( sub {
# do something
my @args = @_;
});
insteads of:
for my $a ( qw/a b c/ ) {
for my $b ( qw/x y z/ ) {
for my $c ( 1 .. 7 ) {
print "Looping.. " , join(',',$a,$b,$c) , "\n";
}
}
}
mfor
mfor {
my @args = @_; # get a,x,1 in first loop
print "Looping.. " , join(',',@_) , "\n";
} [
[ qw/a b c/ ],
[ qw/x y z/ ],
[ 1 .. 7 ],
];
it
iterator with hash reference
MFor->it({ L1 => qw|a b c| })->it({ L2 => qw|X Y Z| })
->do(sub {
my $args = shift;
print $args->{L1};
print $args->{L2};
});
conditon with iterator
MFor->it({ L1 => qw|a b c| })->when( qw|L1 eq 'a'| )->do( sub {
# only do something when L1 equal to 'a'
my $args = shift;
})
