| * \brief C API: MessageFormat |
| * |
| * <h2>Message Format C API </h2> |
| * |
| * Provides means to produce concatenated messages in language-neutral way. |
| * Use this for all concatenations that show up to end users. |
| * <P> |
| * Takes a set of objects, formats them, then inserts the formatted |
| * strings into the pattern at the appropriate places. |
| * <P> |
| * Here are some examples of usage: |
| * Example 1: |
| * <pre> |
| * \code |
| * UChar *result, *tzID, *str; |
| * UChar pattern[100]; |
| * int32_t resultLengthOut, resultlength; |
| * UCalendar *cal; |
| * UDate d1; |
| * UDateFormat *def1; |
| * UErrorCode status = U_ZERO_ERROR; |
| * |
| * str=(UChar*)malloc(sizeof(UChar) * (strlen("disturbance in force") +1)); |
| * u_uastrcpy(str, "disturbance in force"); |
| * tzID=(UChar*)malloc(sizeof(UChar) * 4); |
| * u_uastrcpy(tzID, "PST"); |
| * cal=ucal_open(tzID, u_strlen(tzID), "en_US", UCAL_TRADITIONAL, &status); |
| * ucal_setDateTime(cal, 1999, UCAL_MARCH, 18, 0, 0, 0, &status); |
| * d1=ucal_getMillis(cal, &status); |
| * u_uastrcpy(pattern, "On {0, date, long}, there was a {1} on planet {2,number,integer}"); |
| * resultlength=0; |
| * resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, d1, str, 7); |
| * if(status==U_BUFFER_OVERFLOW_ERROR){ |
| * status=U_ZERO_ERROR; |
| * resultlength=resultLengthOut+1; |
| * result=(UChar*)realloc(result, sizeof(UChar) * resultlength); |
| * u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, d1, str, 7); |
| * } |
| * printf("%s\n", austrdup(result) );//austrdup( a function used to convert UChar* to char*) |
| * //output>: "On March 18, 1999, there was a disturbance in force on planet 7 |
| * \endcode |
| * </pre> |
| * Typically, the message format will come from resources, and the |
| * arguments will be dynamically set at runtime. |
| * <P> |
| * Example 2: |
| * <pre> |
| * \code |
| * UChar* str; |
| * UErrorCode status = U_ZERO_ERROR; |
| * UChar *result; |
| * UChar pattern[100]; |
| * int32_t resultlength, resultLengthOut, i; |
| * double testArgs= { 100.0, 1.0, 0.0}; |
| * |
| * str=(UChar*)malloc(sizeof(UChar) * 10); |
| * u_uastrcpy(str, "MyDisk"); |
| * u_uastrcpy(pattern, "The disk {1} contains {0,choice,0#no files|1#one file|1<{0,number,integer} files}"); |
| * for(i=0; i<3; i++){ |
| * resultlength=0; |
| * resultLengthOut=u_formatMessage( "en_US", pattern, u_strlen(pattern), NULL, resultlength, &status, testArgs[i], str); |
| * if(status==U_BUFFER_OVERFLOW_ERROR){ |
| * status=U_ZERO_ERROR; |
| * resultlength=resultLengthOut+1; |
| * result=(UChar*)malloc(sizeof(UChar) * resultlength); |
| * u_formatMessage( "en_US", pattern, u_strlen(pattern), result, resultlength, &status, testArgs[i], str); |
| * } |
| * printf("%s\n", austrdup(result) ); //austrdup( a function used to convert UChar* to char*) |
| * free(result); |
| * } |
| * // output, with different testArgs: |
| * // output: The disk "MyDisk" contains 100 files. |
| * // output: The disk "MyDisk" contains one file. |
| * // output: The disk "MyDisk" contains no files. |
| * \endcode |
| * </pre> |
| * |
| * |
| * Example 3: |
| * <pre> |
| * \code |
| * UChar* str; |
| * UChar* str1; |
| * UErrorCode status = U_ZERO_ERROR; |
| * UChar *result; |
| * UChar pattern[100]; |
| * UChar expected[100]; |
| * int32_t resultlength,resultLengthOut; |
| |
| * str=(UChar*)malloc(sizeof(UChar) * 25); |
| * u_uastrcpy(str, "Kirti"); |
| * str1=(UChar*)malloc(sizeof(UChar) * 25); |
| * u_uastrcpy(str1, "female"); |
| * log_verbose("Testing message format with Select test #1\n:"); |
| * u_uastrcpy(pattern, "{0} est {1, select, female {all\\u00E9e} other {all\\u00E9}} \\u00E0 Paris."); |
| * u_uastrcpy(expected, "Kirti est all\\u00E9e \\u00E0 Paris."); |
| * resultlength=0; |
| * resultLengthOut=u_formatMessage( "fr", pattern, u_strlen(pattern), NULL, resultlength, &status, str , str1); |
| * if(status==U_BUFFER_OVERFLOW_ERROR) |
| * { |
| * status=U_ZERO_ERROR; |
| * resultlength=resultLengthOut+1; |
| * result=(UChar*)malloc(sizeof(UChar) * resultlength); |
| * u_formatMessage( "fr", pattern, u_strlen(pattern), result, resultlength, &status, str , str1); |
| * if(u_strcmp(result, expected)==0) |
| * log_verbose("PASS: MessagFormat successful on Select test#1\n"); |
| * else{ |
| * log_err("FAIL: Error in MessageFormat on Select test#1\n GOT %s EXPECTED %s\n", austrdup(result), |
| * austrdup(expected) ); |
| * } |
| * free(result); |
| * } |
| * \endcode |
| * </pre> |
| * |
| |
| * The pattern is of the following form. Legend: |
| * <pre> |
| * \code |
| * {optional item} |
| * (group that may be repeated)* |
| * \endcode |
| * </pre> |
| * Do not confuse optional items with items inside quotes braces, such |
| * as this: "{". Quoted braces are literals. |
| * <pre> |
| * \code |
| * messageFormatPattern := string ( "{" messageFormatElement "}" string )* |
| * |
| * messageFormatElement := argument { "," elementFormat } |
| * |
| * elementFormat := "time" { "," datetimeStyle } |
| * | "date" { "," datetimeStyle } |
| * | "number" { "," numberStyle } |
| * | "choice" "," choiceStyle |
| * | "select" "," selectStyle |
| * |
| * datetimeStyle := "short" |
| * | "medium" |
| * | "long" |
| * | "full" |
| * | dateFormatPattern |
| * |
| * numberStyle := "currency" |
| * | "percent" |
| * | "integer" |
| * | numberFormatPattern |
| * |
| * choiceStyle := choiceFormatPattern |
| * |
| * selectStyle := selectFormatPattern |
| * \endcode |
| * </pre> |
| * If there is no elementFormat, then the argument must be a string, |
| * which is substituted. If there is no dateTimeStyle or numberStyle, |
| * then the default format is used (e.g. NumberFormat.getInstance(), |
| * DateFormat.getDefaultTime() or DateFormat.getDefaultDate(). For |
| * a ChoiceFormat, the pattern must always be specified, since there |
| * is no default. |
| * <P> |
| * In strings, single quotes can be used to quote the "{" sign if |
| * necessary. A real single quote is represented by ''. Inside a |
| * messageFormatElement, quotes are [not] removed. For example, |
| * {1,number,$'#',##} will produce a number format with the pound-sign |
| * quoted, with a result such as: "$#31,45". |
| * <P> |
| * If a pattern is used, then unquoted braces in the pattern, if any, |
| * must match: that is, "ab {0} de" and "ab '}' de" are ok, but "ab |
| * {0'}' de" and "ab } de" are not. |
| * <p> |
| * <dl><dt><b>Warning:</b><dd>The rules for using quotes within message |
| * format patterns unfortunately have shown to be somewhat confusing. |
| * In particular, it isn't always obvious to localizers whether single |
| * quotes need to be doubled or not. Make sure to inform localizers about |
| * the rules, and tell them (for example, by using comments in resource |
| * bundle source files) which strings will be processed by MessageFormat. |
| * Note that localizers may need to use single quotes in translated |
| * strings where the original version doesn't have them. |
| * <br>Note also that the simplest way to avoid the problem is to |
| * use the real apostrophe (single quote) character U+2019 (') for |
| * human-readable text, and to use the ASCII apostrophe (U+0027 ' ) |
| * only in program syntax, like quoting in MessageFormat. |
| * See the annotations for U+0027 Apostrophe in The Unicode Standard.</p> |
| * </dl> |
| * <P> |
| * The argument is a number from 0 to 9, which corresponds to the |
| * arguments presented in an array to be formatted. |
| * <P> |
| * It is ok to have unused arguments in the array. With missing |
| * arguments or arguments that are not of the right class for the |
| * specified format, a failing UErrorCode result is set. |
| * <P> |
| |
| * <P> |
| * [Note:] As we see above, the string produced by a choice Format in |
| * MessageFormat is treated specially; occurances of '{' are used to |
| * indicated subformats. |
| * <P> |
| * [Note:] Formats are numbered by order of variable in the string. |
| * This is [not] the same as the argument numbering! |
| * <pre> |
| * \code |
| * For example: with "abc{2}def{3}ghi{0}...", |
| * |
| * format0 affects the first variable {2} |
| * format1 affects the second variable {3} |
| * format2 affects the second variable {0} |
| * \endcode |
| * </pre> |
| * and so on. |
