NAME

Log::Report::Domain - administer one text-domain

INHERITANCE

Log::Report::Domain
  is a Log::Report::Minimal::Domain

SYNOPSIS

# internal usage
use Log::Report::Domain;
my $domain = Log::Report::Domain->new(name => $name);

# find a ::Domain object
use Log::Report 'my-domain';
my $domain = textdomain 'my-domain'; # find domain config
my $domain = textdomain;             # config of this package

# explicit domain configuration
package My::Package;
use Log::Report 'my-domain';         # set textdomain for package

textdomain $name, %configure;        # set config, once per program
(textdomain $name)->configure(%configure); # same
textdomain->configure(%configure);   # same if current package in $name

# implicit domain configuration
package My::Package;
use Log::Report 'my-domain', %configure;

# external file for configuration (perl or json format)
use Log::Report 'my-domain', config => $filename;

use Log::Report 'my-domain';
textdomain->configure(config => $filename);

DESCRIPTION

Log::Report can handle multiple sets of packages at the same time: in the usual case a program consists of more than one software distribution, each containing a number of packages. Each module in an application belongs to one of these sets, by default the domain set 'default'.

For Log::Report, those packags sets are differentiated via the text-domain value in the use statement:

use Log::Report 'my-domain';

There are many things you can configure per (text)domain. This is not only related to translations, but also -for instance- for text formatting configuration. The administration for the configuration is managed in this package.

Log::Report::Domain->new(%options)

Create a new Domain object.

-Option--Defined in                  --Default
 name    Log::Report::Minimal::Domain  <required>
name => STRING

Attributes

Extends "Attributes" in Log::Report::Minimal::Domain.

$obj->configure(%options)

The import is automatically called when the package is compiled. For all but one packages in your distribution, it will only contain the name of the DOMAIN. For one package, it will contain configuration information. These %options are used for all packages which use the same DOMAIN. See chapter "Configuring" below.

-Option         --Defined in                  --Default
 config                                         undef
 context_rules                                  undef
 formatter                                      PRINTI
 native_language                                'en_US'
 translator                                     created internally
 where            Log::Report::Minimal::Domain  <required>
config => FILENAME

Read the settings from the file. The parameters found in the file are used as default for the parameters above. This parameter is especially useful for the context_rules, which need to be shared between the running application and xgettext-perl. See readConfig()

context_rules => HASH|OBJECT

When rules are provided, the translator will use the msgctxt fields as provided by PO-files (gettext). This parameter is used to initialize a Log::Report::Translator::Context helper object.

formatter => CODE|'PRINTI'|'PRINTP'

Selects the formatter used for the errors messages. The default is PRINTI, which will use String::Print::printi(): interpolation with curly braces around the variable names. PRINTP uses positional parameters, just like printf, implemented by String::Print::printp().

native_language => CODESET

This is the language which you have used to write the translatable and the non-translatable messages in. In case no translation is needed, you still wish the system error messages to be in the same language as the report. Of course, each textdomain can define its own.

translator => Log::Report::Translator|HASH

Set the object which will do the translations for this domain.

where => ARRAY
$obj->contextRules()
$obj->defaultContext()

Returns the current default translation context settings as HASH. You should not modify the content of that HASH: change it by called setContext().

$obj->isConfigured()

Inherited, see "Attributes" in Log::Report::Minimal::Domain

$obj->name()

Inherited, see "Attributes" in Log::Report::Minimal::Domain

$obj->nativeLanguage()
$obj->readConfig($filename)
Log::Report::Domain->readConfig($filename)

Helper method, which simply parses the content $filename into a HASH to be used as parameters to configure(). The filename must end on '.pl', to indicate that it uses perl syntax (can be processed with Perl's do command) or end on '.json'. See also chapter "Configuring" below.

Currently, this file can be in Perl native format (when ending on .pl) or JSON (when it ends with .json). Various modules may explain parts of what can be found in these files, for instance Log::Report::Translator::Context.

$obj->setContext(STRING|HASH|ARRAY|PAIRS)

Temporary set the default translation context for messages. This is used when the message is created without a _context parameter. The context can be retrieved with defaultContext().

Contexts are totally ignored then there are no context_rules.

$obj->translator()

Action

Extends "Action" in Log::Report::Minimal::Domain.

Log::Report::Domain->interpolate( $msgid, [$args] )

Inherited, see "Action" in Log::Report::Minimal::Domain

$obj->translate($message, $language)

Translate the $message into the $language.

DETAILS

Configuring

Configuration of a domain can happen in many ways: either explicitly or implicitly. The explicit form:

package My::Package;
use Log::Report 'my-domain';

textdomain 'my-domain', %configuration;
textdomain->configure(%configuration);
textdomain->configure(\%configuration);

textdomain->configure(conf => $filename);

The implicit form is

package My::Package;
use Log::Report 'my-domain', %configuration;
use Log::Report 'my-domain', conf => $filename;

You can only configure your domain in one place in your program. The textdomain setup is then used for all packages in the same domain.

This also works for Log::Report::Optional, which is a dressed-down version of Log::Report.

configuring your formatter

The PRINTI and PRINTP are special constants for configure(formatter), and will use String::Print functions printi() respectively printp() in their default modus. When you want your own formatter, or configuration of String::Print, you need to pass a code reference.

my $sp = String::Print->new
  ( modifiers   => ...
  , serializers => ...
  );

textdomain 'some-domain'
  , formatter => sub { $sp->printi(@_) };
