DESCRIPTION

48       Utils to expand placeholders in BabelFish style.
49
50       Placeholders are also extendable with attributes to run the modifier
51       code.  That is an extention to BabelFish style.
52

SUBROUTINES/METHODS

54   method new
55       see SYNOPSIS
56
57   method is_strict
58       If is_strict is false: undef will be converted to q{}.  If is_strict is
59       true: no replacement.
60
61           $obj->is_strict(1); # boolean true or false;
62
63   method default_modifier_code
64       Implements the html attribute.  For plain text messages in HTML the
65       whole message will be escaped.  In case of HTML messages the
66       placeholder data have to escaped.
67
68           # class method
69           my $modifier_code = Locale::Utils::PlaceholderBabelFish->default_modifier_code;
70           # object method
71           my $modifier_code = $obj->default_modifier_code;
72
73           # call example
74           $value = $modifier_code->($value, $attributes);
75
76   method modifier_code, clear_modifier_code
77       The modifier code handles named attributes to modify the given
78       placeholder value.
79
80       If the placeholder name is "#{foo:bar}" then foo is the placeholder
81       name and bar the attribute name.  Space in front of the attribute name
82       is allowed, e.g. "#{foo :bar}".
83
84           my $code_ref = sub {
85               my ( $value, $attributes ) = @_;
86               return
87                   $attributes =~ m{ \b numf \b }
88                   ? $value =~ tr{.}{,}
89                   : $attribute =~ m{ \b accusative \b }xms
90                   ? accusative($value)
91                   : $value;
92           };
93           $obj->modifier_code($code_ref);
94
95       To switch off this code - clear them.
96
97           $obj->clear_modifier_code;
98
99   method expand_babel_fish
100       Expands strings containing BabelFish placeholders.
101
102       variables and attributes
103
104           #{name}
105           #{name :attr_name}
106
107       plural with default "count" or other name for count
108
109           ((Singular|Plural))
110           ((Singular|Plural)):other
111
112       plural with special count 0
113
114           ((=0 Zero|Singular|Plural))
115           ((=0 Zero|Singular|Plural)):other
116
117       plural with placeholder
118
119           ((#{count} Singular|#{count} Plural))
120           ((#{other} Singular|#{other} Plural)):other
121
122       plural with placeholder and attributes
123
124           ((#{count :attr_name} Singular|#{count} Plural))
125           ((#{other :attr_name} Singular|#{other} Plural)):other
126
127           $expanded = $obj->expand_babel_fish($babel_fish_text, $count);
128           $expanded = $obj->expand_babel_fish($babel_fish_text, count => $count);
129           $expanded = $obj->expand_babel_fish($babel_fish_text, { count => $count, key => $value });
