SYNOPSIS

use Locale::Utils::PlaceholderBabelFish;

my $obj = Locale::Utils::PlaceholderBabelFish->new(
    # optional is_strict switch
    is_strict => 1,
    # optional modifier code
    modifier_code => sub {
        my ( $value, $attribute ) = @_;
        return
            $attribute eq '%.3f'
            ? sprintf($attribute, $value)
            : $attribute eq 'accusative'
            ? accusative($value)
            : $value;
    },
    # optional plural code
    plural_code => sub { # the default for English
        my $n = shift;
        0 + (
            $n != 1 # en
        );
    },

$expanded = $obj->expand_babel_fish($text, \%arg_of);

DESCRIPTION

Utils to expand placeholders in BabelFish style.

Placeholders are also extendable with attributes to run the modifier code. That is an extention to BabelFish style.

SUBROUTINES/METHODS

method is_strict

If is_strict is false: undef will be converted to q{}. If is_strict is true: no replacement.

$obj->is_strict(1); # boolean true or false;

method modifier_code, clear_modifier_code

The modifier code handles named attributes to modify the given placeholder value.

If the placeholder name is #{foo:bar} then foo is the placeholder name and bar the attribute name. Space in front of the attribute name is allowed, e.g. #{foo :bar}.

my $code_ref = sub {
    my ( $value, $attribute ) = @_;
    return
        $attribute eq 'num.03'
        ? sprintf('%.03f, $value)
        : $attribute eq 'accusative'
        ? accusative($value)
        : $value;
};
$obj->modifier_code($code_ref);

To switch off this code - clear them.

$obj->clear_modifier_code;

method expand_babel_fish

Expands strings containing BabelFish placeholders.

variables and attributes

#{name}
#{name :attr_name}

plural with default count or other name for count

((Singular|Plural))
((Singular|Plural)):other

plural with special count 0

((=0 Zero|Singular|Plural))
((=0 Zero|Singular|Plural)):other

plural with placeholder

((#{count} Singular|#{count} Plural))
((#{other} Singular|#{other} Plural)):other

plural with placeholder and attributes

((#{count :attr_name} Singular|#{count} Plural))
((#{other :attr_name} Singular|#{other} Plural)):other

$expanded = $obj->expand_babel_fish($babel_fish_text, $count);
$expanded = $obj->expand_babel_fish($babel_fish_text, count => $count);
$expanded = $obj->expand_babel_fish($babel_fish_text, { count => $count, key => $value });
