NAME

List::Slice - Slice-like operations on lists

VERSION

version 0.003

SYNOPSIS

    use List::Slice qw( head tail );

DESCRIPTION

This module provides functions for slicing lists. This is helpful when you want to do a chain of manipulations on a list (map, grep, sort) and then slice, without the cumbersome (...)[x] syntax.

FUNCTIONS

head

    my @values = head $size, @list;

Returns the first $size elements from @list. If $size is negative, returns all but the last $size elements from @list.

    @result = head 2, qw( foo bar baz );
    # foo, bar

    @result = head -2, qw( foo bar baz );
    # foo

tail

    my @values = tail $size, @list;

Returns the last $size elements from @list. If $size is negative, returns all but the first $size elements from @list.

    @result = tail 2, qw( foo bar baz );
    # bar, baz

    @result = tail -2, qw( foo bar baz );
    # baz
