## NAME

Catmandu::I18N - tools for text localisation

## SYNOPSIS

```
    use Catmandu::Sane;
    use Catmandu::I18N;
    my $i = Catmandu::I18N->new(
        config => {
            en => [
              "Gettext",
              "/path/to/en.po"
            ],
            nl => [
              "Gettext",
              "/path/to/nl.po"
            ]
        }
    );
    $i->t( "my-lang", "my-key" );
    $i->t( "my-lang", "my-key2", "arg-1", "arg-2" );
```

## CONSTRUCTOR ARGUMENTS

- config

  Configuration for Locale::Maketext.

  Must be either:

  \* hash reference

  \* string (e.g. "i18n")

  When the config is a string, it is interpreted as the path to the I18N configuration in Catmandu config.

  Required

- on\_failure

  What to do when a lookup does not give a result.

  Possible values:

  \* "undef" : return undef

  \* "auto" : return key itself. Always a result.

  \* "die" : die

  Default: "undef"

  Note: "undef" should be a string, as opposed to undef.

- fallback\_languages

  array of fallback language codes

  \* must be array reference

  \* default is \[ "i-default","en","en-US" \] as determined by Locale::Maketext

  When Locale::Maketext does not find the specified language in your config, it will fallback to one of these, and then load the handle for that.

  Only if that fallback language does not exist in the config, will it fail.

  Example 1:

  fallback\_languages is \[ "en" \]

  you have only language "en" in your config, but you request language "nl", then you'll get the message in English.

  Example 2:

  fallback\_languages is \[ "en" \]

  you have only language "nl" in your config, but you request language "fr", then the creation of the message will fail

  You can set this to an empty array for consistent behaviour.

## NOTES

\* the lexicon implementation determines the format of the message.

e.g. only Locale::Maketext::Lexicon::Gettext supports placeholders like `%1`.

For other implementations you need to use placeholders like \[\_1\]
