=head1 SYNOPSIS |
14
|
|
|
|
|
|
|
|
15
|
|
|
|
|
|
|
BEGIN { # put share in a BEGIN block |
16
|
|
|
|
|
|
|
use Rex::Shared::Var; |
17
|
|
|
|
|
|
|
share qw($scalar @array %hash); # share the listed variables |
18
|
|
|
|
|
|
|
} |

|
22
|
|
|
|
|
|
|
Currently nesting data structures works only if the assignment is made on the top level of the structure, or when the nested structures are also shared variables. For example: |
23
|
|
|
|
|
|
|
|
24
|
|
|
|
|
|
|
BEGIN { |
25
|
|
|
|
|
|
|
use Rex::Shared::Var; |
26
|
|
|
|
|
|
|
share qw(%hash %nested); |
27
|
|
|
|
|
|
|
} |
28
|
|
|
|
|
|
|
|
29
|
|
|
|
|
|
|
# this doesn't work as expected |
30
|
|
|
|
|
|
|
$hash{key} = { nested_key => 42 }; |
31
|
|
|
|
|
|
|
$hash{key}->{nested_key} = -1; # $hash{key}->{nested_key} still returns 42 |
32
|
|
|
|
|
|
|
|
33
|
|
|
|
|
|
|
# workaround 1 - top level assignments |
34
|
|
|
|
|
|
|
$hash{key} = { nested_key => 42 }; |
35
|
|
|
|
|
|
|
$hash{key} = { nested_key => -1 }; |
36
|
|
|
|
|
|
|
|
37
|
|
|
|
|
|
|
# workaround 2 - nesting shared variables |
38
|
|
|
|
|
|
|
$nested{nested_key} = 42; |
39
|
|
|
|
|
|
|
$hash{key} = \%nested; |
40
|
|
|
|
|
|
|
$hash{key}->{nested_key} = -1; |
