Detailed Description

C API: MessageFormat.

MessageFormat C API

MessageFormat prepares strings for display to users, with optional arguments (variables/placeholders). The arguments can occur in any order, which is necessary for translation into languages with different grammars.

The opaque UMessageFormat type is a thin C wrapper around a C++ MessageFormat. It is constructed from a pattern string with arguments in {curly braces} which will be replaced by formatted values.

Currently, the C API supports only numbered arguments.

For details about the pattern syntax and behavior, especially about the ASCII apostrophe vs. the real apostrophe (single quote) character ’ (U+2019), see the C++ MessageFormat class documentation.

Here are some examples of C API usage: Example 1:

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);
}

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");

◆ umsg_autoQuoteApostrophe()

U_CAPI int32_t umsg_autoQuoteApostrophe	(	const UChar *	pattern,
		int32_t	patternLength,
		UChar *	dest,
		int32_t	destCapacity,
		UErrorCode *	ec
	)

Convert an 'apostrophe-friendly' pattern into a standard pattern.

Standard patterns treat all apostrophes as quotes, which is problematic in some languages, e.g. French, where apostrophe is commonly used. This utility assumes that only an unpaired apostrophe immediately before a brace is a true quote. Other unpaired apostrophes are paired, and the resulting standard pattern string is returned.

Note it is not guaranteed that the returned pattern is indeed a valid pattern. The only effect is to convert between patterns having different quoting semantics.

Parameters

pattern	the 'apostrophe-friendly' patttern to convert
patternLength	the length of pattern, or -1 if unknown and pattern is null-terminated
dest	the buffer for the result, or NULL if preflight only
destCapacity	the length of the buffer, or 0 if preflighting
ec	the error code

Returns: the length of the resulting text, not including trailing null if buffer has room for the trailing null, it is provided, otherwise not

This function performs a deep copy.

Parameters

fmt	The formatter to copy
status	A pointer to an UErrorCode to receive any errors.

Returns: A pointer to a UDateFormat identical to fmt.
