|
|
*
|
|
* <h2> ULoc C API for Locale </h2>
|
|
* A <code>Locale</code> represents a specific geographical, political,
|
|
* or cultural region. An operation that requires a <code>Locale</code> to perform
|
|
* its task is called <em>locale-sensitive</em> and uses the <code>Locale</code>
|
|
* to tailor information for the user. For example, displaying a number
|
|
* is a locale-sensitive operation--the number should be formatted
|
|
* according to the customs/conventions of the user's native country,
|
|
* region, or culture. In the C APIs, a locales is simply a const char string.
|
|
*
|
|
* <P>
|
|
* You create a <code>Locale</code> with one of the three options listed below.
|
|
* Each of the component is separated by '_' in the locale string.
|
|
* \htmlonly<blockquote>\endhtmlonly
|
|
* <pre>
|
|
* \code
|
|
* newLanguage
|
|
*
|
|
* newLanguage + newCountry
|
|
*
|
|
* newLanguage + newCountry + newVariant
|
|
* \endcode
|
|
* </pre>
|
|
* \htmlonly</blockquote>\endhtmlonly
|
|
* The first option is a valid <STRONG>ISO
|
|
* Language Code.</STRONG> These codes are the lower-case two-letter
|
|
* codes as defined by ISO-639.
|
|
* You can find a full list of these codes at a number of sites, such as:
|
|
* <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt">
|
|
* http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a>
|
|
*
|
|
* <P>
|
|
* The second option includes an additional <STRONG>ISO Country
|
|
* Code.</STRONG> These codes are the upper-case two-letter codes
|
|
* as defined by ISO-3166.
|
|
* You can find a full list of these codes at a number of sites, such as:
|
|
* <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html">
|
|
* http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a>
|
|
*
|
|
* <P>
|
|
* The third option requires another additional information--the
|
|
* <STRONG>Variant.</STRONG>
|
|
* The Variant codes are vendor and browser-specific.
|
|
* For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX.
|
|
* Where there are two variants, separate them with an underscore, and
|
|
* put the most important one first. For
|
|
* example, a Traditional Spanish collation might be referenced, with
|
|
* "ES", "ES", "Traditional_WIN".
|
|
*
|
|
* <P>
|
|
* Because a <code>Locale</code> is just an identifier for a region,
|
|
* no validity check is performed when you specify a <code>Locale</code>.
|
|
* If you want to see whether particular resources are available for the
|
|
* <code>Locale</code> you asked for, you must query those resources. For
|
|
* example, ask the <code>UNumberFormat</code> for the locales it supports
|
|
* using its <code>getAvailable</code> method.
|
|
* <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular
|
|
* locale, you get back the best available match, not necessarily
|
|
* precisely what you asked for. For more information, look at
|
|
* <code>UResourceBundle</code>.
|
|
*
|
|
* <P>
|
|
* The <code>Locale</code> provides a number of convenient constants
|
|
* that you can use to specify the commonly used
|
|
* locales. For example, the following refers to a locale
|
|
* for the United States:
|
|
* \htmlonly<blockquote>\endhtmlonly
|
|
* <pre>
|
|
* \code
|
|
* ULOC_US
|
|
* \endcode
|
|
* </pre>
|
|
* \htmlonly</blockquote>\endhtmlonly
|
|
*
|
|
* <P>
|
|
* Once you've specified a locale you can query it for information about
|
|
* itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and
|
|
* <code>uloc_getLanguage</code> to get the ISO Language Code. You can
|
|
* use <code>uloc_getDisplayCountry</code> to get the
|
|
* name of the country suitable for displaying to the user. Similarly,
|
|
* you can use <code>uloc_getDisplayLanguage</code> to get the name of
|
|
* the language suitable for displaying to the user. Interestingly,
|
|
* the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive
|
|
* and have two versions: one that uses the default locale and one
|
|
* that takes a locale as an argument and displays the name or country in
|
|
* a language appropriate to that locale.
|
|
*
|
|
* <P>
|
|
* The ICU provides a number of services that perform locale-sensitive
|
|
* operations. For example, the <code>unum_xxx</code> functions format
|
|
* numbers, currency, or percentages in a locale-sensitive manner.
|
|
* </P>
|
|
* \htmlonly<blockquote>\endhtmlonly
|
|
* <pre>
|
|
* \code
|
|
* UErrorCode success = U_ZERO_ERROR;
|
|
* UNumberFormat *nf;
|
|
* const char* myLocale = "fr_FR";
|
|
*
|
|
* nf = unum_open( UNUM_DEFAULT, NULL, success );
|
|
* unum_close(nf);
|
|
* nf = unum_open( UNUM_CURRENCY, NULL, success );
|
|
* unum_close(nf);
|
|
* nf = unum_open( UNUM_PERCENT, NULL, success );
|
|
* unum_close(nf);
|
|
* \endcode
|
|
* </pre>
|
|
* \htmlonly</blockquote>\endhtmlonly
|
|
* Each of these methods has two variants; one with an explicit locale
|
|
* and one without; the latter using the default locale.
|
|
* \htmlonly<blockquote>\endhtmlonly
|
|
* <pre>
|
|
* \code
|
|
*
|
|
* nf = unum_open( UNUM_DEFAULT, myLocale, success );
|
|
* unum_close(nf);
|
|
* nf = unum_open( UNUM_CURRENCY, myLocale, success );
|
|
* unum_close(nf);
|
|
* nf = unum_open( UNUM_PERCENT, myLocale, success );
|
|
* unum_close(nf);
|
|
* \endcode
|
|
* </pre>
|
|
* \htmlonly</blockquote>\endhtmlonly
|
|
* A <code>Locale</code> is the mechanism for identifying the kind of services
|
|
* (<code>UNumberFormat</code>) that you would like to get. The locale is
|
|
* <STRONG>just</STRONG> a mechanism for identifying these services.
|
|
*
|
|
* <P>
|
|
* Each international service that performs locale-sensitive operations
|
|
* allows you
|
|
* to get all the available objects of that type. You can sift
|
|
* through these objects by language, country, or variant,
|
|
* and use the display names to present a menu to the user.
|
|
* For example, you can create a menu of all the collation objects
|
|
* suitable for a given language. Such classes implement these
|
|
* three class methods:
|
|
* \htmlonly<blockquote>\endhtmlonly
|
|
* <pre>
|
|
* \code
|
|
* const char* uloc_getAvailable(int32_t index);
|
|
* int32_t uloc_countAvailable();
|
|
* int32_t
|
|
* uloc_getDisplayName(const char* localeID,
|
|
* const char* inLocaleID,
|
|
* UChar* result,
|
|
* int32_t maxResultSize,
|
|
* UErrorCode* err);
|
|
*
|
|
* \endcode
|
|
* </pre>
|
|
* \htmlonly</blockquote>\endhtmlonly
|
|
* <P>
|
|
* Concerning POSIX/RFC1766 Locale IDs,
|
|
* the getLanguage/getCountry/getVariant/getName functions do understand
|
|
* the POSIX type form of language_COUNTRY.ENCODING\@VARIANT
|
|
* and if there is not an ICU-stype variant, uloc_getVariant() for example
|
|
* will return the one listed after the \@at sign. As well, the hyphen
|
|
* "-" is recognized as a country/variant separator similarly to RFC1766.
|
|
* So for example, "en-us" will be interpreted as en_US.
|
|
* As a result, uloc_getName() is far from a no-op, and will have the
|
|
* effect of converting POSIX/RFC1766 IDs into ICU form, although it does
|
|
* NOT map any of the actual codes (i.e. russian->ru) in any way.
|
|
* Applications should call uloc_getName() at the point where a locale ID
|
|
* is coming from an external source (user entry, OS, web browser)
|
|
* and pass the resulting string to other ICU functions. For example,
|
|
* don't use de-de\@EURO as an argument to resourcebundle.
