NAME
Util::Any - Export any utilities and To create your own Util::Any
VERSION
Version 0.04
SYNOPSIS
use Util::Any qw/list/;
# you can import any functions of List::Util and List::MoreUtils
print uniq qw/1, 0, 1, 2, 3, 3/;
If you want to choose functions
use Util::Any {list => qw/uniq/};
# you can import uniq function, not import other functions
print uniq qw/1, 0, 1, 2, 3, 3/;
If you want to import All kind of utility functions
use Util::Any qw/all/;
my $o = bless {};
my %hash = (a => 1, b => 2);
# from Scalar::Util
blessed $o;
# from Hash::Util
lock_keys %hash;
If you want to import functions with prefix(ex. list_, scalar_, hash_)
use Util::Any qw/all/, {prefix => 1};
use Util::Any qw/list/, {prefix => 1};
use Util::Any {List => qw/uniq/}, {prefix => 1};
print list_uniq qw/1, 0, 1, 2, 3, 3/;
DESCRIPTION
For the people like the man who cannot remember uniq
function is in whether List::Util or List::MoreUtils. And for the newbie who don't know where useful utilities is.
Perl has many modules and they have many utility functions. For example, List::Util, List::MoreUtils, Scalar::Util, Hash::Util, String::Util, String::CamelCase, Data::Dumper etc.
We, Perl users, have to memorize modules name and their functions name. Using this module, you don't need to memorize modules name, only memorize kinds of modules and functions name.
And this module allows you to create your own utility module, easily. You can create your own module and use this in the same way as Util::Any like the following.
use YourUtil qw/list/;
see CREATE YOUR OWN Util::Any
, in detail.
HOW TO USE
use Util::Any (KIND)
use Util::Any qw/list hash/;
Give list of kinds of modules. All functions in moduls are exporeted.
use Util::Any {KIND => [FUNCTIONS], ...};
use Util::Any {list => ['uniq'], hash => ['lock_keys']};
Give hash ref whose key is kind and value is function names. Selected functions are exported.
use Util::Any ..., {OPTION => VALUE};
Util::Any can take last argument as option, which should be hash ref.
- prefix => 1
-
add kind prefix to function name.
use Util::Any qw/list/, {prefix => 1}; list_uniq(1,2,3,4,5); # it is List::More::Utils's uniq function
- module_prefix => 1
-
see "PREFIX FOR EACH MODULE". Uti::Any itself doesn't have such a definition.
- debug => 1/2
-
Util::Any doesn't say anything when loading module fails. If you pass debug value, warn or die.
use Util::Any qw/list/, {debug => 1}; # warn use Util::Any qw/list/, {debug => 2}; # die

CREATE YOUR OWN Util::Any
Just inherit Util::Any and define $Utils hash ref as the following.
package Util::Yours;
use Clone qw/clone/;
use base qw/Util::Any/;
our $Utils = clone $Util::Any::Utils;
push @{$Utils->{list}}, qw/Your::Favorite::List::Utils/;
1;
In your code;
use Util::Yours qw/list/;
$Utils STRUCTURE
overview
$Utils => {
# simply put module names
kind1 => [qw/Module1 Module2 ..../],
# Module name and its prefix
kind2 => [ [Module1 => 'module_prefix'], ... ],
# limit functions to be exported
kind3 => [ [Module1, 'module_prefix', [qw/func1 func2/] ], ... ],
# as same as above except not specify modul prefix
kind4 => [ [Module1, '', [qw/func1 func2/] ], ... ],
};
Key must be lower character.
NG $Utils = { LIST => [qw/List::Util/]};
OK $Utils = { list => [qw/List::Util/]};
all
cannot be used for key.
NG $Utils = { all => [qw/List::Util/]};
Value is array ref which contained scalar or array ref.
Scalar is module name. Array ref is module name and its prefix.
$Utils = { list => ['List::Utils'] };
$Utils = { list => [['List::Utils', 'prefix_']] };
PREFIX FOR EACH MODULE
If you want to import many modules and they have same function name. You can specify prefix for each module like the following.
use base qw/Util::Any/;
our $Utils = {
list => [['List::Util' => 'lu_'], ['List::MoreUtils' => 'lmu_']]
};
In your code;
use Util::Yours qw/list/, {module_prefix => 1};
OTHER WAY TO EXPORT FUNCTIONS
SELECT FUNCTIONS
Util::Any auomaticaly export functions from modules' @EXPORT and @EXPORT_OK. In some cases, it is not good idea like Data::Dumper's Dumper and DumperX.
So you can limit functions to be exported.
our $Utils = {
debug => [
['Data::Dumper', '',
['Dumper']], # only Dumper method is exported.
],
};
or
our $Utils = {
debug => [
['Data::Dumper', '',
{ -select => ['Dumper'] }, # only Dumper method is exported.
]
],
};
SELECT FUNCTIONS EXCEPT
Inverse of -select option. Cannot use this option with -select.
our $Utils = {
debug => [
['Data::Dumper', '',
{ -except => ['DumperX'] }, # export functions except DumperX
]
],
};
RENAME FUNCTIONS
To rename function name. Using this option with -select or -exception, this definition is prior to them.
In the following example, 'min' is not in -select list, but can be exported.
our $Utils = {
list => [
[
'List::Util', '',
{
'first' => 'list_first', # first as list_first
'sum' => 'lsum', # sum as lsum
'min' => 'lmin', # min as lmin
-select => ['first', 'sum', 'shuffle'],
}
]
],
};
