        numf_comma => 1,   # set option numf_comma
    );

        # you set 'nbsp' on a string which you see in the Browser.

DESCRIPTION

Object methods like quant don't have interpreted into strings. The module ties the method quant to a hash. The object method quant is executed at fetch hash. At long last this is the same, only the notation is shorter.

You can use the module also without Locale::Maketext::TieHash::L10N. Whether this is better for you, have decide you.

SUBROUTINES/METHODS

method TIEHASH

    use Locale::Maketext::TieHash::quant;
    tie my %quant, 'Locale::Maketext::TieHash::quant', %config;

'TIEHASH' ties your hash and set options defaults.

method config

'config' configures the language handle and/or options.

    # configure the language handle
    tied(%quant)->config(L10N => $lh);

    # configure option of language handle
    tied(%quant)->config(numf_comma => 1);
    # the same is:
    $lh->{numf_comma} = 1;

    # only for debugging your HTML response
    tied(%quant)->config(
        nbsp => 'see_position_of_nbsp_in_HTML_response',
    ); # default is ' '

    # Set a flag to say:
    #  Substitute the whitespace before this flag and this flag to ' '
    #  or your debugging string.
    # The "nbsp_flag" is a string (1 or more characters).
    tied(%quant)->config(nbsp_flag => '~');

    # You get the string 'singular,plural,zero' from any data base.
    # - As if the 'nbsp_flag' in front of 'singular' would stand.
    tied(%quant)->config(auto_nbsp_flag1 => 1);
    # - As if the 'nbsp_flag' in front of 'plural' would stand.
    tied(%quant)->config(auto_nbsp_flag2 => 1);

The method calls croak, if the key of your hash is undef or your key isn't correct and if the value, you set to option 'nbsp', is undef.

'config' accepts all parameters as Hash and gives a Hash back with all attitudes.

method FETCH

'FETCH' is quantifying the given key of your hash and give back the translated string as value.

    # quantifying
    print $quant{"$number singular,plural,zero"};
    # the same is:
    print $lh->quant($number, 'singular', 'plural', 'zero');
    ...
    # Use 'nbsp' and 'nbsp_flag', 'auto_nbsp_flag1' and 'auto_nbsp_flag2' are true.
    print $quant{"$number singular,plural,zero"};
    # the same is:
    my $result = $lh->quant($number, '~' . 'singular', '~' . 'plural', 'zero');
    $result =~ s{[ ] ~}{ }xmsg; # But not a global debugging function is available.

The method calls croak, if the method 'quant' of your stored language handle dies.
