|
| - *
|
| - * ICU trace format string syntax
|
| - *
|
| - * Format Strings are passed to UTraceData functions, and define the
|
| - * number and types of the trace data being passed on each call.
|
| - *
|
| - * The UTraceData function, which is supplied by the application,
|
| - * not by ICU, can either forward the trace data (passed via
|
| - * varargs) and the format string back to ICU for formatting into
|
| - * a displayable string, or it can interpret the format itself,
|
| - * and do as it wishes with the trace data.
|
| - *
|
| - *
|
| - * Goals for the format string
|
| - * - basic data output
|
| - * - easy to use for trace programmer
|
| - * - sufficient provision for data types for trace output readability
|
| - * - well-defined types and binary portable APIs
|
| - *
|
| - * Non-goals
|
| - * - printf compatibility
|
| - * - fancy formatting
|
| - * - argument reordering and other internationalization features
|
| - *
|
| - * ICU trace format strings contain plain text with argument inserts,
|
| - * much like standard printf format strings.
|
| - * Each insert begins with a '%', then optionally contains a 'v',
|
| - * then exactly one type character.
|
| - * Two '%' in a row represent a '%' instead of an insert.
|
| - * The trace format strings need not have \n at the end.
|
| - *
|
| - *
|
| - * Types
|
| - * -----
|
| - *
|
| - * Type characters:
|
| - * - c A char character in the default codepage.
|
| - * - s A NUL-terminated char * string in the default codepage.
|
| - * - S A UChar * string. Requires two params, (ptr, length). Length=-1 for nul term.
|
| - * - b A byte (8-bit integer).
|
| - * - h A 16-bit integer. Also a 16 bit Unicode code unit.
|
| - * - d A 32-bit integer. Also a 20 bit Unicode code point value.
|
| - * - l A 64-bit integer.
|
| - * - p A data pointer.
|
| - *
|
| - * Vectors
|
| - * -------
|
| - *
|
| - * If the 'v' is not specified, then one item of the specified type
|
| - * is passed in.
|
| - * If the 'v' (for "vector") is specified, then a vector of items of the
|
| - * specified type is passed in, via a pointer to the first item
|
| - * and an int32_t value for the length of the vector.
|
| - * Length==-1 means zero or NUL termination. Works for vectors of all types.
|
| - *
|
| - * Note: %vS is a vector of (UChar *) strings. The strings must
|
| - * be nul terminated as there is no way to provide a
|
| - * separate length parameter for each string. The length
|
| - * parameter (required for all vectors) is the number of
|
| - * strings, not the length of the strings.
|
| - *
|
| - * Examples
|
| - * --------
|
| - *
|
| - * These examples show the parameters that will be passed to an application's
|
| - * UTraceData() function for various formats.
|
| - *
|
| - * - the precise formatting is up to the application!
|
| - * - the examples use type casts for arguments only to _show_ the types of
|
| - * arguments without needing variable declarations in the examples;
|
| - * the type casts will not be necessary in actual code
|
| - *
|
| - * UTraceDataFunc(context, fnNumber, level,
|
| - * "There is a character %c in the string %s.", // Format String
|
| - * (char)c, (const char *)s); // varargs parameters
|
| - * -> There is a character 0x42 'B' in the string "Bravo".
|
| - *
|
| - * UTraceDataFunc(context, fnNumber, level,
|
| - * "Vector of bytes %vb vector of chars %vc",
|
| - * (const uint8_t *)bytes, (int32_t)bytesLength,
|
| - * (const char *)chars, (int32_t)charsLength);
|
| - * -> Vector of bytes
|
| - * 42 63 64 3f [4]
|
| - * vector of chars
|
| - * "Bcd?"[4]
|
| - *
|
| - * UTraceDataFunc(context, fnNumber, level,
|
| - * "An int32_t %d and a whole bunch of them %vd",
|
| - * (int32_t)-5, (const int32_t *)ints, (int32_t)intsLength);
|
| - * -> An int32_t 0xfffffffb and a whole bunch of them
|
| - * fffffffb 00000005 0000010a [3]
