NAME
Log::Report::Domain - administer one text-domain
INHERITANCE
Log::Report::Domain
is a Log::Report::Minimal::Domain
Log::Report::Domain is extended by
Log::Report::Template::Textdomain
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.
Extends "DESCRIPTION" in Log::Report::Minimal::Domain.
METHODS
Extends "METHODS" in Log::Report::Minimal::Domain.
Constructors
Extends "Constructors" in Log::Report::Minimal::Domain.
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|HASH|'PRINTI'
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.
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() or updateContext().
$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". When you do not wish
to change settings, you may simply provide a HASH.
example:
use Log::Report 'my-domain', context_rules => {};
$obj->translator()
$obj->updateContext(STRING|HASH|ARRAY|PAIRS)
[1.10] Make changes and additions to the active context (see setContext()).
Action
Extends "Action" in Log::Report::Minimal::Domain.
$obj->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 (no variables possible, only constants!)
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 own formatter
[0.91] The "PRINTI" is a special constants for configure(formatter), and will use
String::Print function "printi()", with the standard tricks.
textdomain 'some-domain'
formatter =>
{ class => 'String::Print' # default
, method => 'sprinti' # default
, %options # constructor options for the class
);
When you want your own formatter, or configuration of "String::Print", you need to pass a
CODE. Be aware that you may loose magic added by Log::Report and other layers, like
Log::Report::Template:
textdomain 'some-domain'
, formatter => \&my_formatter;
configuring global values
Say, you log for a (Dancer) webserver, where you wish to include the website name in some
of the log lines. For this, (ab)use the translation context:
### first enabled translation contexts
use Log::Report 'my-domain', context_rules => {};
# or
use Log::Report 'my-domain';
textdomain->configure(context_rules => {});
# or
textdomain 'my-domain'
, content_rules => {};
### every time you start working for a different virtual host
(textdomain 'my-domain')->setContext(host => $host);
### now you can use that in your code
package My::Package;
use Log::Report 'my-domain';
error __x"in {_context.host} not logged-in {user}", user => $username;
