NAME

Locale::Maketext::TieHash::L10N - Tying language handle to a hash

SYNOPSIS

use strict;
use Locale::Maketext::TieHash::L10N;
tie my %mt, 'Locale::Maketext::TieHash::L10N';
{ use MyProgram::L10N;
  my $lh = MyProgram::L10N->get_handle() || die "What language?";
  # store language handle
  $mt{L10N} = $lh;
}
# store option numf_comma
$mt{numf_comma} = 1;
...
print qq~$mt{Example}:\n$mt{["Can't open file [_1]: [_2].", $f, $!]}\n~;

The way without this module - You better see the difference.

use strict;
use MyProgram::L10N;
my $lh = MyProgram::L10N->get_handle() || die "What language?";
$lh{numf_comma} = 1;
...
print $lh->maketext('Example') . ":\n" . $lh->maketext("Can't open file [_1]: [_2].", $f, $!) . "\n";

Example for writing HTML

use strict;
use Locale::Maketext::TieHash::L10N;
tie my %mt, 'Locale::Maketext::TieHash::L10N';
{ use MyProgram::L10N;
  my $lh = MyProgram::L10N->get_handle() || die "What language?";
  # store language handle
  $mt{L10N} = $lh;
}
# store option numf_comma and set the nbsp_flag to '~';
@mt{qw/numf_comma nbsp_flag/} = qw/1 ~/;
# If you want to test your Script, you set "nbsp" on a string which you see in the Browser.
$mt{nbsp} = '<span style="color:red">§</span>';
...
# The browser shows value and unity always on a line.
print qq#$mt{["Put [*,_1,~component,~components,no component] together, then have [*,_2,~piece,~pieces,no piece] of equipment.", $component, $piece]}\n#;

get the language handle "L10N", "nbsp" and/or "nbsp_flag" back

# You can get the language handle "L10N", "nbsp" and/or "nbsp_flag" back on this way.
my ($lh, $nbsp, $nbsp_flag) = tied(%mt)->Get(qw/L10N nbsp nbsp_flag/);
# You can get the keys "L10N", "nbsp" and "nbsp_flag" back on this way.
my @keys = tied(%mt)->Keys();
# You can get the values of "L10N", "nbsp" and "nbsp_flag" back on this way.
my @values = tied(%mt)->Values();
# This is the way to store values of keys in another tyed hash like %mt.
my %hash;
@hash{tied(%mt)->Keys} = tied(%mt)->Values;

DESCRIPTION

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

Sometimes the object method "maketext" expects more than 1 parameter. Then submit a reference on an array as hash key.

If you write HTML text with "Locale::Maketext", it then can happen that value and unity stand on separate lines. The "nbsp_flag" prevents the line break. The "nbsp_flag" per default is undef and this functionality is switched off. Set your choice this value on a character string. For switching the functionality off, set the value to undef or a character string of the length 0. "nbsp" per default is " ".

METHODS

TIEHASH

use Locale::Maketext::TieHash::L10N;
tie my %mt, 'Locale::Maketext::TieHash::L10N';

"TIEHASH" ties your hash and set options defaults.

STORE

"STORE" stores the language handle or options.

# store the language handle
$mt{L10N} = $lh;

# store option of language handle
$mt{numf_comma} = 1;
# the same is:
$lh->{numf_comma} = 1;

# only for debugging your HTML response
$mt{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).
$mt{nbsp_flag} = '~';

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.

FETCH

"FETCH" translate the given key of your hash and give back the translated string as value.

# translation
print $mt{'you write this language'};
# the same is:
print $lh->maketext('you write this language');
...
print $mt{['Put [*,_1,component,components,no component] together.', $number]};
# the same is:
print $lh->maketext('Put [*,_1,component,components,no component] together.', $number);
...
# Use "nbsp" and the "nbsp_flag" is true.
print $mt{['Put [*,_1,~component,~components,no component] together.', $number]};
# the same is:
my $translation = $lh->maketext('Put [*,_1,~component,~components,no component] together.', $number);
$tanslation =~ s/ ~/ /g;   # But not a global debugging function is available.

The method calls croak, if the method "maketext" of your stored language handle dies.

Keys

Get all keys back.

Values

Get all values back.

Get

Submit 1 key or more. The method "Get" give you the values back.

The method calls croak if a key is undef or unknown.
