NAME

Syntax::Keyword::Combine::Keys - ckeys keyword

VERSION

Version 0.09

SYNOPSIS

        use Syntax::Keyword::Combine::Keys;

        my %hash = ckeys {
                $_ => $HASH{$_}->{value};
        } %{$hash1}, %hash2, e => { value => 500 };

DESCRIPTION

This ia an experimental module written for learning purposes. The module provides a single keyword - ckeys, most simply put it is a modification of map being passed the sorted keys of a hash. To demonstrate further the following is the "pure" perl equivalent of the synopsis.

        my %HASH = (%{$hash1}, %hash2, e => { value => 500 };
        my %hash = map {
                $_ => $HASH{$_}->{value};
        } sort keys %HASH;

KEYWORDS

ckeys

        my @keys = ckeys {
                uc $_;
        } %hash1, %hash2, %hash3

Repeatedly calls the block of code, with $_ locally set to each key from the given list. It Returns the processed values from the block. ckeys also exposes a variable called %HASH which contains the merged list that is passed to the block.

        %HASH = ( %hash1, %hash2, $hash3 );
