| 29 * \brief C API: Locale | |
| 30 * | |
| 31 * <h2> ULoc C API for Locale </h2> | |
| 32 * A <code>Locale</code> represents a specific geographical, political, | |
| 33 * or cultural region. An operation that requires a <code>Locale</code> to perfo
rm | |
| 34 * its task is called <em>locale-sensitive</em> and uses the <code>Locale</code> | |
| 35 * to tailor information for the user. For example, displaying a number | |
| 36 * is a locale-sensitive operation--the number should be formatted | |
| 37 * according to the customs/conventions of the user's native country, | |
| 38 * region, or culture. In the C APIs, a locales is simply a const char string. | |
| 39 * | |
| 40 * <P> | |
| 41 * You create a <code>Locale</code> with one of the three options listed below. | |
| 42 * Each of the component is separated by '_' in the locale string. | |
| 43 * \htmlonly<blockquote>\endhtmlonly | |
| 44 * <pre> | |
| 45 * \code | |
| 46 * newLanguage | |
| 47 * | |
| 48 * newLanguage + newCountry | |
| 49 * | |
| 50 * newLanguage + newCountry + newVariant | |
| 51 * \endcode | |
| 52 * </pre> | |
| 53 * \htmlonly</blockquote>\endhtmlonly | |
| 54 * The first option is a valid <STRONG>ISO | |
| 55 * Language Code.</STRONG> These codes are the lower-case two-letter | |
| 56 * codes as defined by ISO-639. | |
| 57 * You can find a full list of these codes at a number of sites, such as: | |
| 58 * <BR><a href ="http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt"> | |
| 59 * http://www.ics.uci.edu/pub/ietf/http/related/iso639.txt</a> | |
| 60 * | |
| 61 * <P> | |
| 62 * The second option includes an additonal <STRONG>ISO Country | |
| 63 * Code.</STRONG> These codes are the upper-case two-letter codes | |
| 64 * as defined by ISO-3166. | |
| 65 * You can find a full list of these codes at a number of sites, such as: | |
| 66 * <BR><a href="http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html"> | |
| 67 * http://www.chemie.fu-berlin.de/diverse/doc/ISO_3166.html</a> | |
| 68 * | |
| 69 * <P> | |
| 70 * The third option requires another additonal information--the | |
| 71 * <STRONG>Variant.</STRONG> | |
| 72 * The Variant codes are vendor and browser-specific. | |
| 73 * For example, use WIN for Windows, MAC for Macintosh, and POSIX for POSIX. | |
| 74 * Where there are two variants, separate them with an underscore, and | |
| 75 * put the most important one first. For | |
| 76 * example, a Traditional Spanish collation might be referenced, with | |
| 77 * "ES", "ES", "Traditional_WIN". | |
| 78 * | |
| 79 * <P> | |
| 80 * Because a <code>Locale</code> is just an identifier for a region, | |
| 81 * no validity check is performed when you specify a <code>Locale</code>. | |
| 82 * If you want to see whether particular resources are available for the | |
| 83 * <code>Locale</code> you asked for, you must query those resources. For | |
| 84 * example, ask the <code>UNumberFormat</code> for the locales it supports | |
| 85 * using its <code>getAvailable</code> method. | |
| 86 * <BR><STRONG>Note:</STRONG> When you ask for a resource for a particular | |
| 87 * locale, you get back the best available match, not necessarily | |
| 88 * precisely what you asked for. For more information, look at | |
| 89 * <code>UResourceBundle</code>. | |
| 90 * | |
| 91 * <P> | |
| 92 * The <code>Locale</code> provides a number of convenient constants | |
| 93 * that you can use to specify the commonly used | |
| 94 * locales. For example, the following refers to a locale | |
| 95 * for the United States: | |
| 96 * \htmlonly<blockquote>\endhtmlonly | |
| 97 * <pre> | |
| 98 * \code | |
| 99 * ULOC_US | |
| 100 * \endcode | |
| 101 * </pre> | |
| 102 * \htmlonly</blockquote>\endhtmlonly | |
| 103 * | |
| 104 * <P> | |
| 105 * Once you've specified a locale you can query it for information about | |
| 106 * itself. Use <code>uloc_getCountry</code> to get the ISO Country Code and | |
| 107 * <code>uloc_getLanguage</code> to get the ISO Language Code. You can | |
| 108 * use <code>uloc_getDisplayCountry</code> to get the | |
| 109 * name of the country suitable for displaying to the user. Similarly, | |
| 110 * you can use <code>uloc_getDisplayLanguage</code> to get the name of | |
| 111 * the language suitable for displaying to the user. Interestingly, | |
| 112 * the <code>uloc_getDisplayXXX</code> methods are themselves locale-sensitive | |
| 113 * and have two versions: one that uses the default locale and one | |
| 114 * that takes a locale as an argument and displays the name or country in | |
| 115 * a language appropriate to that locale. | |
| 116 * | |
| 117 * <P> | |
| 118 * The ICU provides a number of services that perform locale-sensitive | |
| 119 * operations. For example, the <code>unum_xxx</code> functions format | |
| 120 * numbers, currency, or percentages in a locale-sensitive manner. | |
| 121 * </P> | |
| 122 * \htmlonly<blockquote>\endhtmlonly | |
| 123 * <pre> | |
| 124 * \code | |
| 125 * UErrorCode success = U_ZERO_ERROR; | |
| 126 * UNumberFormat *nf; | |
| 127 * const char* myLocale = "fr_FR"; | |
| 128 * | |
| 129 * nf = unum_open( UNUM_DEFAULT, NULL, success ); | |
| 130 * unum_close(nf); | |
| 131 * nf = unum_open( UNUM_CURRENCY, NULL, success ); | |
| 132 * unum_close(nf); | |
| 133 * nf = unum_open( UNUM_PERCENT, NULL, success ); | |
| 134 * unum_close(nf); | |
| 135 * \endcode | |
| 136 * </pre> | |
| 137 * \htmlonly</blockquote>\endhtmlonly | |
| 138 * Each of these methods has two variants; one with an explicit locale | |
| 139 * and one without; the latter using the default locale. | |
| 140 * \htmlonly<blockquote>\endhtmlonly | |
| 141 * <pre> | |
| 142 * \code | |
| 143 * | |
| 144 * nf = unum_open( UNUM_DEFAULT, myLocale, success ); | |
| 145 * unum_close(nf); | |
| 146 * nf = unum_open( UNUM_CURRENCY, myLocale, success ); | |
| 147 * unum_close(nf); | |
| 148 * nf = unum_open( UNUM_PERCENT, myLocale, success ); | |
| 149 * unum_close(nf); | |
| 150 * \endcode | |
| 151 * </pre> | |
| 152 * \htmlonly</blockquote>\endhtmlonly | |
| 153 * A <code>Locale</code> is the mechanism for identifying the kind of services | |
| 154 * (<code>UNumberFormat</code>) that you would like to get. The locale is | |
| 155 * <STRONG>just</STRONG> a mechanism for identifying these services. | |
| 156 * | |
| 157 * <P> | |
| 158 * Each international serivce that performs locale-sensitive operations | |
| 159 * allows you | |
| 160 * to get all the available objects of that type. You can sift | |
| 161 * through these objects by language, country, or variant, | |
| 162 * and use the display names to present a menu to the user. | |
| 163 * For example, you can create a menu of all the collation objects | |
| 164 * suitable for a given language. Such classes implement these | |
| 165 * three class methods: | |
| 166 * \htmlonly<blockquote>\endhtmlonly | |
| 167 * <pre> | |
| 168 * \code | |
| 169 * const char* uloc_getAvailable(int32_t index); | |
| 170 * int32_t uloc_countAvailable(); | |
| 171 * int32_t | |
| 172 * uloc_getDisplayName(const char* localeID, | |
| 173 * const char* inLocaleID, | |
| 174 * UChar* result, | |
| 175 * int32_t maxResultSize, | |
| 176 * UErrorCode* err); | |
| 177 * | |
| 178 * \endcode | |
| 179 * </pre> | |
| 180 * \htmlonly</blockquote>\endhtmlonly | |
| 181 * <P> | |
| 182 * Concerning POSIX/RFC1766 Locale IDs, | |
| 183 * the getLanguage/getCountry/getVariant/getName functions do understand | |
| 184 * the POSIX type form of language_COUNTRY.ENCODING\@VARIANT | |
| 185 * and if there is not an ICU-stype variant, uloc_getVariant() for example | |
| 186 * will return the one listed after the \@at sign. As well, the hyphen | |
| 187 * "-" is recognized as a country/variant separator similarly to RFC1766. | |
| 188 * So for example, "en-us" will be interpreted as en_US. | |
| 189 * As a result, uloc_getName() is far from a no-op, and will have the | |
| 190 * effect of converting POSIX/RFC1766 IDs into ICU form, although it does | |
| 191 * NOT map any of the actual codes (i.e. russian->ru) in any way. | |
| 192 * Applications should call uloc_getName() at the point where a locale ID | |
| 193 * is coming from an external source (user entry, OS, web browser) | |
| 194 * and pass the resulting string to other ICU functions. For example, | |
| 195 * don't use de-de\@EURO as an argument to resourcebundle. | |
