CHAPTER 8: ExtendScript Tools and Features Localizing ExtendScript strings 226

5. If not found, it removes the region identifier (for example, en) and retries.

6. If not found, it tries the identifier

en (that is, the default language is English).

7. If not found, it returns the entire localizer object.

Testing localization

ExtendScript stores the current locale in the variable $.locale. This variable is updated whenever the

locale of the hosting application changes.

To test your localized strings, you can temporarily reset the locale. To restore the original behavior, set the

variable to

null, false, 0, or the empty string. An example:

$.locale = "ru"; // try your Russian messages

$.locale = null; // restore to the locale of the app

Global localize function

The globally available localize function can be used to provide localized strings anywhere a displayed

text value is specified. The function takes a specially formatted set of localized versions of a display string,

and returns the version appropriate to the current locale.

localize()

localize (localization_obj[, args])

localize (ZString)

localization_obj

A JavaScript object literal whose property names are locale names, and

whose property values are the localized text strings. The locale name is an

identifier as specified in the ISO 3166 standard, a set of two-letter language

abbreviations, such as "

en" for English and "de" for German.

For example:

btnText = { en: "Yes", de: "Ja", fr: "Oui" };

b1 = w.add ("button", undefined, localize (btnText));

The string value of each property can contain variables in the form %1, %2,

and so on, corresponding to additional arguments. The variable is replaced

with the result of evaluating the corresponding argument in the returned

string.

args

Optional. Additional JavaScript expressions matching variables in the string

values supplied in the localization object. The first argument corresponds to

the variable

%1, the second to %2, and so on.

Each expression is evaluated and the result inserted in the variable’s position

in the returned string.

ZString

Internal use only. A ZString is an internal Adobe format for localized strings,

which you might see in Adobe scripts. It is a string that begins with

$$$ and

contains a path to the localized string in an installed ZString dictionary. For

example:

w = new Window ("dialog", localize ("$$$/UI/title1=Sample"));
