NAME

Util::Underscore - Common helper functions without having to import them

VERSION

version v1.0.1

SYNOPSIS

use Util::Underscore;

_::croak "$foo must do Some::Role" if not _::does($foo, 'Some::Role');

DESCRIPTION

This module contains various utility functions, and makes them accessible through the _ package. This allows the use of these utilities (a) without much per-usage overhead and (b) without namespace pollution.

It contains functions from the following modules:

Not all functions from those are available, and some have been renamed.

FUNCTION REFERENCE

Scalar::Util

$str = _::blessed $object
$str = _::class $object

wrapper for Scalar::Util::blessed

$int = _::ref_addr $ref

wrapper for Scalar::Util::refaddr

$str = _::ref_type $ref

wrapper for Scalar::Util::reftype

_::ref_weaken $ref

wrapper for Scalar::Util::weaken

_::ref_unweaken $ref

wrapper for Scalar::Util::unweaken

$bool = _::ref_is_weak $ref

wrapper for Scalar::Util::isweak

$scalar = _::new_dual $num, $str

wrapper for Scalar::Util::dualvar

$bool = _::is_dual $scalar

wrapper for Scalar::Util::isdual

$bool = _::is_vstring $scalar

wrapper for Scalar::Util::isvstring

$bool = _::is_numeric $scalar

wrapper for Scalar::Util::looks_like_number

$fh = _::is_open $fh

wrapper for Scalar::Util::openhandle

$bool = _::is_readonly $scalar

wrapper for Scalar::Util::readonly

$str = _::prototype \&code
_::prototype \&code, $new_proto

gets or sets the prototype, wrapping either CORE::prototype or Scalar::Util::set_prototype

$bool = _::is_tainted $scalar

wrapper for Scalar::Util::tainted

List::Util and List::MoreUtils

$scalar = _::reduce { BLOCK } @list

wrapper for List::Util::reduce

$bool = _::any { PREDICATE } @list

wrapper for List::Util::any

$bool = _::all { PREDICATE } @list

wrapper for List::Util::all

$bool = _::none { PREDICATE } @list

wrapper for List::Util::none

$scalar = _::first { PREDICATE } @list

wrapper for List::MoreUtils::first_value

$int = _::first_index { PREDICATE } @list

wrapper for List::MoreUtils::first_index

$scalar = _::last { PREDICATE } @list

wrapper for List::MoreUtils::last_value

$int = _::last_index { PREDICATE } @list

wrapper for List::MoreUtils::last_index

$num = _::max @list
$str = _::max_str @list

wrappers for List::Util::max and List::Util::maxstr, respectively.

$num = _::min @list
$str = _::min_str @list

wrappers for List::Util::min and List::Util::minstr, respectively.

$num = _::sum 0, @list

wrapper for List::Util::sum

$num = _::product @list

wrapper for List::Util::product

%kvlist = _::pairgrep { PREDICATE } %kvlist

wrapper for List::Util::pairgrep

($k, $v) = _::pairfirst { PREDICATE } %kvlist

wrapper for List::Util::pairfirst

%kvlist = _::pairmap { BLOCK } %kvlist

wrapper for List::Util::pairmap

@list = _::shuffle @list

wrapper for List::Util::shuffle

$iter = _::natatime $size, @list

wrapper for List::MoreUtils::natatime

@list = _::zip \@array1, \@array2, ...

wrapper for List::MoreUtils::zip

Unlike List::MoreUtils::zip, this function directly takes array references, and not array variables. It still uses the same implementation. This change makes it easier to work with anonymous arrayrefs, or other data that isn't already inside a named array variable.

@list = _::uniq @list

wrapper for List::MoreUtils::uniq

@list = _::part { INDEX_FUNCTION } @list

wrapper for List::MoreUtils::part

$iter = _::each_array \@array1, \@array2, ...

wrapper for List::MoreUtils::each_arrayref

Carp

_::carp "Message"

wrapper for Carp::carp

_::cluck "Message"

wrapper for Carp::cluck

_::croak "Message"

wrapper for Carp::croak

_::confess "Message"

wrapper for Carp::confess

UNIVERSAL

...and other goodies from Safe::Isa

$bool = _::isa $object, 'Class'

wrapper for $Safe::Isa::_isa

$code = _::can $object, 'method'

wrapper for $Safe::Isa::_can

$bool = _::does $object, 'Role'

wrapper for $Safe::Isa::_DOES

any = $maybe_object->_::safecall(method => @args)

wrapper for $Safe::Isa::_call_if_object

Try::Tiny

The following keywords are available:

  • _::try

  • _::catch

  • _::finally

They are all direct aliases for their namesakes in Try::Tiny.
