我有大量数据另存为Data :: Dumper输出。
我应该如何读取这些数据？我想对其进行重组，但是我完全迷失了这种方法。数据结构是数组中的哈希，它们是哈希的哈希...
这是一个（非常精简的）示例。另外，创作也不是很好，因为角色可以有两个“攻击”或两个“特殊”，所以很明显这是一次碰撞，一个将被覆盖。
编辑：我真正要问的是：这是存储数据的理想方式吗？或者，还有更好的方法？因为对我来说，访问哈希$char_hash{Character Name}{abilities}{attack}{tiers}{level 1}{description}似乎很难写。遍历像@{$char_hash{Character Name}{Equipment}{Equipment Level 1}{Items}}疯狂的事情
my @char_hash = (
"Character Name" => {
"description" => "",

"ex 1",
"ex 2",
"ex 4",
"ex 5"
],

"Strength (STR)" => "22",

},

我会说，有更好的方法。
答案是-使用面向对象的代码。如果您还没有真正认识到OO，那么它听起来可能会令人生畏-而且有很多Java或C ++程序员都喜欢这样做。
但实际上，它是一个数据结构，其中包含“内置”代码以对其进行操作。这些代码位称为“方法”，适用于对象。
所以-采取上述措施。您具有“字符”和“设备”作为“对象”的清晰示例。
#!/usr/bin/env perl
package MyStuff::Character;
use strict;
use warnings;
sub new {
my ( $class, $name ) = @_;
my $self = {};
$self -> {name} = $name;
bless $self, $class;
return $self;
}
sub set_attr {
my ( $self, $attr, $value ) = @_;
$self -> {attr} -> {$attr} = $value;
}
sub get_attr {
my ( $self, $attr ) = @_;
return $self -> {attr} -> {$attr};
}
sub get_name {
my ( $self ) = @_;
return $self -> {name};
}
sub add_item {
my ( $self, $item_ref ) = @_;
push ( @{ $self -> {items} }, $item_ref );
}
sub inventory {
my ( $self ) = @_;
return @{$self->{items}};
}
package MyStuff::Items;
sub new {
my ( $class, $name, $type ) = @_;
my $self = {};
$self -> {name} = $name;
$self -> _set_type($type);
bless $self, $class;
return $self;
}
sub get_name {
my ( $self ) = @_;
return $self -> {name};
}
sub _set_type {
my ( $self, $type ) = @_;
$self -> {type} = $type;
if ( $type eq "sword" ) {
$self -> {attack_bonus} = "+10";
}
}
package main;
use strict;
use warnings;
my $character = MyStuff::Character -> new ( "Joe Beefcake" );
$character -> set_attr('STR', 9000);
print $character -> get_name, " has STR ", $character -> get_attr('STR'),"\n";
my $new_sword = MyStuff::Character -> new ( "Hackmaster", "sword");
$character -> add_item( $new_sword );
print "And is carrying:\n";
foreach my $item ( $character -> inventory ) {
print $item -> get_name,"\n";
}
这是一个非常基本的示例，但是希望说明一种处理复杂数据结构的新方法吗？
具体来说-我们将不需要的东西“交给”要照顾的对象，并使用方法与之交互。因为项目是一个自包含的对象，所以它“知道”它的状态。您可以将其拿走，然后“交给”另一个角色。
这样做的另一个好处是继承。我有一个非常通用的“项目”对象。每个项目都会有您可能要处理的事情-拿起它们，随身携带，出售，然后交给其他人。
但是您可以创建一个“武器”类，该类继承“物品”类（因此您仍然可以给别人用剑），还增加了一些额外的东西-例如攻击力，熟练程度要求，攻击力，等等。
对象定向的概念并不是一个新概念，但在perl中并不常见。有perldoc perlobj一些基础知识。
还有一些软件包可以帮助完成该过程（上述工作独立运行），例如Moose。
对于“保存”和“加载”-有很多可能的选择，而且要视情况而定。
我可能会通过将“字符”和“项目”分别序列化为JSON，然后重新加载/验证来解决。
