        # 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, $count);

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