70
Version 1.8 - 2002/07/10
71
------------------------
72
* Fixed infinite loop in multibyte handling (reported by Gisli Ottarsson).
74
* Added the customizable cprintf/cscanf family which enables to user to specify
75

93
* Added trio_locale_decimal_point, trio_locale_thousand_separator,
94
trio_locale_grouping to overwrite locale settings.
96

116
* Fixed printing of %a-format to be like %e, not like %g.
118
* Fixed floating-point printing of values beyond the machine accuracy.
120
* Fixed %f for printing with large precision.
122
* Fixed the usage of C99 nan(), which caused a crash on OSF/1 (reported by
126
Fixed %p on 64-bit platforms.
128
* Made trio compile with K&R compilers.
131
Fixed bug in trio_asprintf.
137

146
Fixed a number of bugs in the scanning of EOF and the count specifier.
151
* Fixed incorrect handling of return code from TrioReadChar (reported by
154
* Fixed parsing of character class expressions.
156

160
* Fixed %#s to handle whitespaces as non-printable characters.
162

164
* Added new test cases.
167
Version 1.6 - 2002/01/13
168
------------------------
169
* Added dynamic string functions.
171
* Rewrote and extended documentation in JavaDoc (using Doxygen).
173
* Moved and renamed strio functions to triostr.
176
Added definition for Cygwin.
179
Added long double workaround for the HP C/iX compiler.
182
Improved error handling for dynamically allocated strings.
185
Made trionan compile on OpenVMS.
187
* Added 'd' and 'D' as exponent letters when using TRIO_MICROSOFT.
189
* Fixed uninitial memory read for the parameter modifiers.
192
Version 1.5 - 2001/09/08
193
------------------------
194
* Merged with libxml changes.
196
* Moved NaN and Inf handling to separate file to enable reuse in other
200
Fixed TrioGenerateNan for MSVC.
202
* Fixed lots of preprocessor macros and internal data structure names.
205
Version 1.4 - 2001/06/03
206
------------------------
207
* Added hex-float (%a and %A) for scanning.
209
* Added wide character arguments (%ls, %ws, %S, %lc, %wc, and %C) for both
212
* Added mutex callbacks for user-specified specifiers to enable applications to
213
add thread-safety. These are registered with trio_register, where the
214
namespace is set to either ":enter" to lock a mutex, or ":leave" to unlock a
217
* Added equivalence class expressions for scanning. For example, %[[=a=]] scans
218
for all letters in the same equivalence class as the letter 'a' as defined
221
* Changed character class expressions for scanning. The expressions must now
222
be embedded withing an extra set of brackets, e.g. %[[:alpha:]]. This was
223
done to adhere to the syntax of UNIX98 regular expressions.
225
* Added the possibility to specify standard support (TRIO_C99 etc.) as compiler
228
* Fixed conversion of hex-float in StrToDouble.
230
* Fixed formatting of hex-float numbers.
233
Fixed crash on QNX, which happend because some buffers on the stack were too
236
* Fixed default precision for %f and %g (reported by Jose Ortiz)
239
Added the I8, I16, I32, and I64 modifiers.
242
Fixed rounding problem for %e.
245
Fixed various problems with the xlC and Sun C++ compilers.
248
Version 1.3 - 2001/05/16
249
------------------------
250
* trio's treatment of the field width when the %e code was used was not
251
correct (reported by Gisli Ottarsson). It turns out the fraction part should
252
be zero-padded by default and the exponent part should be zero-prefixed if
253
it is only one digit. At least that's how the GNU and Sun libc's work. The
254
trio floating point output looks identical to them now.
256
* Fixed group scanning with modifiers.
258
* Fixed compilation for 64-bit Digital Unix.
261
Fixed compilation of dprintf, which uses read/write, for MSVC.
263
* Fixed various compilation problems on Digital Unix (mainly associated with
267
Version 1.2 - 2001/04/11
268
------------------------
269
* Added autoconf integration. If compiled with HAVE_CONFIG_H the following
270
happens. Firstly, <config.h> is included. Secondly, trio will only be
271
compiled if WITH_TRIO is defined herein. Thirdly, if TRIO_REPLACE_STDIO is
272
defined, only stdio functions that have not been detected by autoconf, i.e.
273
those not defined by HAVE_PRINTF or similar, will be replaced by trio
274
functions (suggested by Daniel Veillard).
276
* Fixed '%m.nf' output. Previously trio did not treat the width properly
277
in all cases (reported by Gisli Ottarsson).
279
* Added explicit promotion for the scanfv family.
281
* Fixed more C++ compilation warnings.
284
Version 1.1 - 2001/02/25
285
------------------------
286
* Added explicit promotion for the printfv familiy. A float must be specified
289
* Fixed positionals for printfv (reported by Gisli Ottarsson).
291
* Fixed an integer to pointer conversion problem on the SGI MIPS C compiler
292
(reported by Gisli Ottarsson).
294
* Fixed ANSI C++ warnings (type casting, and namespace is a reserved keyword).
296
* Added \n to all examples in the documentation to prevent confusion.
298
* Fixed StrSubstringMax
301
Version 1.0 - 2000/12/10
302
------------------------
303
* Bumped Version number.
306
Version 0.25 - 2000/12/09
307
-------------------------
308
* Wrote more documentation.
310
* Improved NaN support and added NaN to regression test.
314
* Added missing getter/setter functions.
317
Version 0.24 - 2000/12/02
318
-------------------------
319
* Added callback functionality for the user-defined specifier (<>). All
320
the necessary functions are defined in triop.h header file. See the
321
documentation for trio_register for further detail.
323
* Wrote initial documentation on the callback functionality.
325
* Added the printfv and scanfv family of functions, which takes a pointer
326
array rather than variadic arguments. Each pointer in the array must point
327
to the associated data (requested by Bruce Korb).
329
* As indicated in version 0.21 the extension modifiers (<>) have now been
332
* Added skipping of thousand-separators in floating-point number scanning.
335
Version 0.23 - 2000/10/21
336
-------------------------
337
* Added width to scanning of floating-point numbers.
339
* Wrote more documentation on trio_printf.
341
* Fixed problem with trailing zeroes after decimal-point.
344
Version 0.22 - 2000/08/06
345
-------------------------
346
* Added LC_CTYPE locale dependent character class expressions to scan lists.
347
Included are [:alnum:], [:alpha:], [:cntrl:], [:digit:], [:graph:],
348
[:lower:], [:print:], [:punct:], [:space:], [:upper:], [:xdigit:]
350
* Added C escapes to alternative string formatting and scanning.
352
* Added StrSubstringMax.
354
* Wrote a little more documentation.
356
* Fixed scanf return values.
358
* Fixed a sign error for non-ascii characters.
361
Version 0.21 - 2000/07/19
362
-------------------------
363
* Converted the documentation to TeX. With latex2man the documentation can
364
automatically be converted into man pages.
366
* Added trio_scanf, trio_vscanf, trio_fscanf, and trio_vfscanf.
368
* Added trio_dprintf, trio_vdprintf, trio_dscanf, and trio_vdscanf. These
369
functions can be used to write and read directly to pipes and sockets (the
370
assume blocking sockets). Stdio buffering is surpassed, so the functions are
371
async-safe. However, reading from stdin (STDIN_FILENO) or writing to stdout
372
(STDOUT_FILENO) reintroduces the buffering.
374
* Added trio_dprintf and trio_vdprintf. These can be used to write directly
375
to pipes and sockets.
378
Added trio_asprintf and trio_vasprintf, which are compatible with the GNU
381
* Added scanlist ranges for group scanning (%[]).
383
* Added width for scanning (missing for floating-point numbers though).
385
* Added variable size modifier (&) to handle system defined types of unknown
386
size. This modifier makes certain assumptions about the integer sizes, which
387
may not be valid on any machine. Consequently, the modifier will remain
388
undocumented, as it may be removed later.
390
* Added \777 and \xFF to alternative string scanning (%#s)
392
* Added the TRIO_REPLACE_STDIO check in the header.
394
* Improved performance of the multibyte character parsing.
396
* Fixed positionals (%n$) which had stopped working.
398
* Fixed hh and ll modifiers to allow exactly two letters and no more.
400
* Fixed ANSI C++ warnings. Also fixed the compiler warning about casting
401
between integer and pointer (this has been annoying me for ages).
403
* Fixed snprintf and vsnprintf with zero buffer size.
405
* Fixed NAN problems (reported by Keith Briggs).
407
* Fixed parsing of multibyte characters. The format string was not correctly
408
advanced in case of a multibyte character.
410
* Renamed many of the internal functions to have more consistant names.
412
* Removed the <quote=c> and <fill=c> modifiers. They are not really worth
413
including. The other <> modifiers may disappear as well.
416
Version 0.20 - 2000/06/05
417
-------------------------
418
* Added intmax_t and ptrdiff_t support.
420
* Added support for LC_NUMERIC grouping.
422
* Added double-dot notation for the conversion base. The style is now
423
%width.precision.base, where any argument can be a number, an asterix
424
indicating a parameter, or be omitted entirely. For example, %*..2i is
425
to specify binary numbers without precision, and with width as a parameter
428
* Added sticky modifier (!), which makes subsequent specifiers of the same
429
type reuse the current modifiers. Inspired by a suggestion from Gary Porter.
431
* Added group scanning (%[]). Scanlist ranges and multibyte sequences are not
434
* Added count scanning (%n).
436
* Changed the number scanning to accept thousand separators and any base.
438
* Fixed positional for parameters. It is possible to write something like
439
%3$*1$.*2$d (which happens to be the same as %*.*d).
441
* Fixed precision of integers.
443
* Fixed parameter flags. Before trio could only handle one parameter flag per
444
specifier, although two (three with double-dot base) were possible.
446
* Fixed isinf() for those platforms where it is unimplemented.
449
Version 0.18 - 2000/05/27
450
-------------------------
451
* Rewrote the entire floating-point formatting function (Danny Dulai had
452
reported several errors and even supplied some patches, which unfortunately
453
were lost due to the refactoring).
455
* Removed the use of strlen() in the declaration of a stack array. This
456
caused problems on some compilers (besides it isn't really ANSI C compliant
457
anyways). Using some arbitrarily chosen maximum value; should examine if
458
some standard defines an upper limit on the length of decimal-point and
459
thousands-separator (sizeof(wchar_t) perhaps?)
461
* Changed the parsing of the format string to be multibyte aware.
464
Version 0.17 - 2000/05/19
465
-------------------------
466
* Added INF, -INF, and NAN for floating-point numbers.
468
* Fixed %#.9g -- alternative with precision.
471
Fixed printing of negative hex numbers
473
* Joerg (last name unknown)
474
Fixed convertion of non-ASCII characters
477
Version 0.16 - 1999/08/06
478
-------------------------
479
* Changed the constness of the second argument of StrFloat and StrDouble. The
480
lack of parameter overloading in C is the reason for the strange use of
481
constness in strtof and strtod.
483
* Cleaned up constness.
486
Version 0.15 - 1999/07/23
487
-------------------------
488
* Fixed the internal representation of numbers from signed to unsigned. Signed
489
numbers posed a problem for large unsigned numbers (reported by Tero)
491
* Fixed a tiny bug in trio_vsprintfcat
493
* Changed the meaning of the max argument of StrAppendMax to be consistant
494
with StrFormatAppendMax. Now it is the maximal size of the entire target
495
buffer, not just the appended size. This makes it easier to avoid buffer
496
overflows (requested by Tero)
499
Version 0.14 - 1999/05/16
500
-------------------------
501
* Added size_t support (just waiting for a C99 compliant compiler to add
502
ptrdiff_t and intmax_t)
504
* Rewrote TrioOutStreamDouble so it does not use the libc sprintf to emulate
505
floating-point anylonger.
507
* Fixed width, precision, and adjustment for numbers and doubles.
510
Version 0.13 - 1999/05/06
511
-------------------------
512
* Fixed zero padding for %d. Now %d will only zero pad if explicitly requested
513
to do so with the 0 flag (reported by Tero).
515
* Fixed an incorrect while() condition in TrioGetString (reported by Tero).
518
Version 0.12 - 1999/04/19
519
-------------------------
520
* Fixed incorrect zero padding of pointers
522
* Added StrHash with STRIO_HASH_PLAIN
524
* Added StrFormatDateMax
527
Version 0.11 - 1999/03/25
528
-------------------------
529
* Made it compile under cygwin
531
* Fixed a bug were TrioPreprocess would return an error if no formatting chars
532
were found (reported by Tero).
537
* Added trio_strerror and TRIO_ERROR_NAME.
539
* Changed the error codes to be positive (as errno)
541
* Fixed two reads of uninitialized memory reported by Purify
543
* Added binary specifiers 'b' and 'B' (like SCO.) ThousandSeparator can be
544
used to separate nibbles (4 bit)
546
* Renamed all Internal* functions to Trio*, which seems like a better
547
namespace (even though it is of no practical interest because these
548
functions are not visible beyond the scope of this file.)
553
* Added hex-float format for StrToDouble
555
* Double references and gaps in the arguments are not allowed (for the %n$
556
format) and in both cases an error code is returned.
558
* Added StrToDouble (and StrToFloat)
563
* Added InStream and OutStream to the trio_T structure.
565
* Started work on TrioScan.
567
* Return values for errors changed. Two macros to unpack the error code has
568
been added to the header.
570
* Shortshort (hh) flag added.
572
* %#s also quotes the quote-char now.
574
* Removed the 'errorInFormat' boolean, which isn't used anymore after the
575
functions bail out with an error instead.
580
* More than MAX_PARAMETERS parametes will now cause the TrioPreprocess()
581
function to return error.
583
* Unknown flags and/or specifiers cause errors too.
585
* Added trio_snprintfcat and trio_vsnprintfcat and the defined name
586
StrFormatAppendMax. They append a formatted string to the end of a string.
588
* Define MAX_PARAMETERS to 128 at all times instead of using NL_ARGMAX when
591
* Added platform fixes for Amiga as suggested by Tero J�nk� <tesaja@utu.fi>
596
* vaprintf did add a zero byte even when it had failed.
598
* Cleaned up the code for locale handling and thousand separator
600
* Added trio_aprintf() and trio_vaprintf(). They return an allocated string.
602
* Added thousands separator for numbers
604
* Added floating point support for *printf
609
* StrMatchCase() called StrMatch() instead of itself recursively
611
* Rewrote the implementation of *printf and *scanf and put all the code in
612
this file. Extended qualifiers and qualifiers from other standards were
615
* Added StrSpanFunction, StrToLong, and StrToUnsignedLong
620
* Made the StrEqual* functions resistant to NULL pointers
622
* Turns out strdup() is no standard at all, and some platforms (I seem to
623
recall HP-UX) has problems with it. Made our own StrDuplicate() instead.
625
* Added StrFormat() and StrFormatMax() to serve as sprintf() and snprintf()
added
removed
