CHANGES -- trio
The changes listed without a name attributed to them were most likely done by
Bjorn Reese and/or Daniel Stenberg.
Version 1.14 - 2010/01/26
-------------------------
* David Byron
Added trio_xstring_append_max.
* Fixed compilation problem on Cygwin due to lack of long double math
(reported by Matthias Andree).
* David Boyce
Added #undef of standard stdio function names before assigning trio functions
to them.
* Matthias Andree
Upgraded configure.in to use new macros instead of obsoleted macros.
* Matthias Andree
Added VPATH to Makefile.in
* Tom Honermann
Fixed problem with subnormal numbers which caused an infinite loop outputting
leading spaces.
* Adam McLaurin
Improved parsing performance by avoiding memset() and memcpy() on character
arrays.
* Gideon Smeding
Fixed %u scanning of signed numbers.
* Gideon Smeding
Fixed group scanning for non-matching input.
* Fixed missing undo of look-ahead reading for scanf functions. This does only
work for the scanf* and fscanf* functions, not dscanf* and cscanf* functions
(reported by Gideon Smeding).
* If the format string is empty, scanf does not attempt to read any input.
* Ralf Junker
Fixed Borland compilation for user-defined specifiers.
Version 1.13 - 2008/11/09
-------------------------
* Ives Aerts
Added the $<format|skip> format for user-defined specifiers, which is
compatible with compiler warnings about mismatches between specifiers and
arguments.
* Added TRIO_DEPRECATED flag (reported by David Boyce)
* Fixed rounding adjustment for long double (reported as bug item #2136686).
* Added Makefile dependency for test target (reported as bug item #2136636).
* David Boyce
Fixed long long support for MSVC.

Maus).
* Olli Savia
Added support for LynxOS.
Version 1.11 - 2006/04/08
-------------------------
* Mark Pickelmann
Fixed trio_unregister. If the first element was removed, the remaining
list would be removed as well.
* Fixed unintended formatting of %e that would result in non-zero numbers
starting with zero (reported by Mark Pickelmann and Gisli Ottarsson).
* Fixed compilation with Sun Workshop 6 (reported by Matthias Andree).
* Fixed accuracy for denormalized numbers (bug item #758327).
* Glen Davidson
Fixed scanning of floating-point numbers without a decimal-point (bug item
#1370427).
* David Byron
Fixed more compiler warnings.
* Fixed compilation of trio_to_long_double and TRIO_FEATURE_FLOAT (reported by
David Byron).
* Fixed precision of large floating-point numbers (bug item #1314524).
* Karl Bochert
Fixed trio_fpclassify_and_signbit to only restore the floating-point
precision.
* Fixed detection of need for ieee option on FreeBSD/Alpha.
* Added TRIO_SNPRINTF_ONLY compilation.
* Fixed trio_to_double by not using strtod() on Tru64/DECC because it does not
support hex-floats.
* Fixed crash on 64 bits machines related to a previous workaround in version
1.9 for uninitialized va_list (reported by Nicolai Tufar, suggestion by
Douglas Gwyn).
* Patrick Jessee
Fixed width calculation for %g.
* Added macros for internal features.
* Jon Foster
Added macros for conditional compilation of many features. Documented all
the features.
* Karl Bochert
Fixed problem with Borland C++, which changes the floating-point precision
for certain math functions (log10() and _fpclass()).
* Karl Bochert
Fixed compilation warnings on Borland C++.
* Removed any occurrence of #elif because Borland C++ reports wrong line
numbers when they are present (reported by Karl Bochert).
* David Byron
Added trio_asprintfv.
* Brian Chapman
Fixed Mac OS X compilation.
* David Byron
Fixed several compiler warnings.
* Fixed printing of out-of-range arguments for %hhd and %hd. These arguments
can be out of range because of default integer promotion.
* Bob Friesenhahn
Fixed installation of header files.
* Joe Orton
Added SHELL to Makefile.in to avoid problems with CShells.

Version 1.8 - 2002/07/10
------------------------
* Fixed infinite loop in multibyte handling (reported by Gisli Ottarsson).
* Added the customizable cprintf/cscanf family which enables to user to specify
input and output stream functions (suggested by Florian Schulze).

* Fixed thousand separator checking.
* Fixed %f scanning to get a float and %lf to get a double.
* Fixed WIN32 compilation (reported by Emmanuel Mogenet)
* Fixed regression test cases to exclude disabled features.
Version 1.7 - 2002/05/07
------------------------
* Fixed trio_to_double to handle hex-floats properly.
* Fixed printing of %a-format to be like %e, not like %g.

* Fixed %f for printing of large numbers.
* Fixed %#s to handle whitespaces as non-printable characters.
* Added trio_isfinite, trio_signbit, and trio_fpclassify.
* Added new test cases.
Version 1.6 - 2002/01/13
------------------------
* Added dynamic string functions.
* Rewrote and extended documentation in JavaDoc (using Doxygen).
* Moved and renamed strio functions to triostr.
* Robert Collins
Added definition for Cygwin.
* Markus Henke
Added long double workaround for the HP C/iX compiler.
* Marc Verwerft
Improved error handling for dynamically allocated strings.
* John Fotheringham
Made trionan compile on OpenVMS.
* Added 'd' and 'D' as exponent letters when using TRIO_MICROSOFT.
* Fixed uninitial memory read for the parameter modifiers.
Version 1.5 - 2001/09/08
------------------------
* Merged with libxml changes.
* Moved NaN and Inf handling to separate file to enable reuse in other
projects.
* Igor Zlatkovic
Fixed TrioGenerateNan for MSVC.
* Fixed lots of preprocessor macros and internal data structure names.
Version 1.4 - 2001/06/03
------------------------
* Added hex-float (%a and %A) for scanning.
* Added wide character arguments (%ls, %ws, %S, %lc, %wc, and %C) for both
printf and scanf.
* Added mutex callbacks for user-specified specifiers to enable applications to
add thread-safety. These are registered with trio_register, where the
namespace is set to either ":enter" to lock a mutex, or ":leave" to unlock a
mutex.
* Added equivalence class expressions for scanning. For example, %[[=a=]] scans
for all letters in the same equivalence class as the letter 'a' as defined
by the locale.
* Changed character class expressions for scanning. The expressions must now
be embedded withing an extra set of brackets, e.g. %[[:alpha:]]. This was
done to adhere to the syntax of UNIX98 regular expressions.
* Added the possibility to specify standard support (TRIO_C99 etc.) as compiler
options.
* Fixed conversion of hex-float in StrToDouble.
* Fixed formatting of hex-float numbers.
* Stan Boehm
Fixed crash on QNX, which happend because some buffers on the stack were too
big.
* Fixed default precision for %f and %g (reported by Jose Ortiz)
* Howard Kapustein
Added the I8, I16, I32, and I64 modifiers.
* Jose Ortiz
Fixed rounding problem for %e.
* Jose Ortiz
Fixed various problems with the xlC and Sun C++ compilers.
Version 1.3 - 2001/05/16
------------------------
* trio's treatment of the field width when the %e code was used was not
correct (reported by Gisli Ottarsson). It turns out the fraction part should
be zero-padded by default and the exponent part should be zero-prefixed if
it is only one digit. At least that's how the GNU and Sun libc's work. The
trio floating point output looks identical to them now.
* Fixed group scanning with modifiers.
* Fixed compilation for 64-bit Digital Unix.
* Igor Zlatkovic
Fixed compilation of dprintf, which uses read/write, for MSVC.
* Fixed various compilation problems on Digital Unix (mainly associated with
va_list).
Version 1.2 - 2001/04/11
------------------------
* Added autoconf integration. If compiled with HAVE_CONFIG_H the following
happens. Firstly, <config.h> is included. Secondly, trio will only be
compiled if WITH_TRIO is defined herein. Thirdly, if TRIO_REPLACE_STDIO is
defined, only stdio functions that have not been detected by autoconf, i.e.
those not defined by HAVE_PRINTF or similar, will be replaced by trio
functions (suggested by Daniel Veillard).
* Fixed '%m.nf' output. Previously trio did not treat the width properly
in all cases (reported by Gisli Ottarsson).
* Added explicit promotion for the scanfv family.
* Fixed more C++ compilation warnings.
Version 1.1 - 2001/02/25
------------------------
* Added explicit promotion for the printfv familiy. A float must be specified
by %hf.
* Fixed positionals for printfv (reported by Gisli Ottarsson).
* Fixed an integer to pointer conversion problem on the SGI MIPS C compiler
(reported by Gisli Ottarsson).
* Fixed ANSI C++ warnings (type casting, and namespace is a reserved keyword).
* Added \n to all examples in the documentation to prevent confusion.
* Fixed StrSubstringMax
Version 1.0 - 2000/12/10
------------------------
* Bumped Version number.
Version 0.25 - 2000/12/09
-------------------------
* Wrote more documentation.
* Improved NaN support and added NaN to regression test.
* Fixed C99 support.
* Added missing getter/setter functions.
Version 0.24 - 2000/12/02
-------------------------
* Added callback functionality for the user-defined specifier (<>). All
the necessary functions are defined in triop.h header file. See the
documentation for trio_register for further detail.
* Wrote initial documentation on the callback functionality.
* Added the printfv and scanfv family of functions, which takes a pointer
array rather than variadic arguments. Each pointer in the array must point
to the associated data (requested by Bruce Korb).
* As indicated in version 0.21 the extension modifiers (<>) have now been
completely removed.
* Added skipping of thousand-separators in floating-point number scanning.
Version 0.23 - 2000/10/21
-------------------------
* Added width to scanning of floating-point numbers.
* Wrote more documentation on trio_printf.
* Fixed problem with trailing zeroes after decimal-point.
Version 0.22 - 2000/08/06
-------------------------
* Added LC_CTYPE locale dependent character class expressions to scan lists.
Included are [:alnum:], [:alpha:], [:cntrl:], [:digit:], [:graph:],
[:lower:], [:print:], [:punct:], [:space:], [:upper:], [:xdigit:]
* Added C escapes to alternative string formatting and scanning.
* Added StrSubstringMax.
* Wrote a little more documentation.
* Fixed scanf return values.
* Fixed a sign error for non-ascii characters.
Version 0.21 - 2000/07/19
-------------------------
* Converted the documentation to TeX. With latex2man the documentation can
automatically be converted into man pages.
* Added trio_scanf, trio_vscanf, trio_fscanf, and trio_vfscanf.
* Added trio_dprintf, trio_vdprintf, trio_dscanf, and trio_vdscanf. These
functions can be used to write and read directly to pipes and sockets (the
assume blocking sockets). Stdio buffering is surpassed, so the functions are
async-safe. However, reading from stdin (STDIN_FILENO) or writing to stdout
(STDOUT_FILENO) reintroduces the buffering.
* Paul Janzen
Added trio_asprintf and trio_vasprintf, which are compatible with the GNU
and BSD interfaces.
* Added scanlist ranges for group scanning (%[]).
* Added width for scanning (missing for floating-point numbers though).
* Added variable size modifier (&) to handle system defined types of unknown
size. This modifier makes certain assumptions about the integer sizes, which
may not be valid on any machine. Consequently, the modifier will remain
undocumented, as it may be removed later.
* Added \777 and \xFF to alternative string scanning (%#s)
* Added the TRIO_REPLACE_STDIO check in the header.
* Improved performance of the multibyte character parsing.
* Fixed positionals (%n$) which had stopped working.
* Fixed hh and ll modifiers to allow exactly two letters and no more.
* Fixed ANSI C++ warnings. Also fixed the compiler warning about casting
between integer and pointer (this has been annoying me for ages).
* Fixed snprintf and vsnprintf with zero buffer size.
* Fixed NAN problems (reported by Keith Briggs).
* Fixed parsing of multibyte characters. The format string was not correctly
advanced in case of a multibyte character.
* Renamed many of the internal functions to have more consistant names.
* Removed the <quote=c> and <fill=c> modifiers. They are not really worth
including. The other <> modifiers may disappear as well.
Version 0.20 - 2000/06/05
-------------------------
* Added intmax_t and ptrdiff_t support.
* Added support for LC_NUMERIC grouping.
* Added double-dot notation for the conversion base. The style is now
%width.precision.base, where any argument can be a number, an asterix
indicating a parameter, or be omitted entirely. For example, %*..2i is
to specify binary numbers without precision, and with width as a parameter
on the va_list.
* Added sticky modifier (!), which makes subsequent specifiers of the same
type reuse the current modifiers. Inspired by a suggestion from Gary Porter.
* Added group scanning (%[]). Scanlist ranges and multibyte sequences are not
supported yet.
* Added count scanning (%n).
* Changed the number scanning to accept thousand separators and any base.
* Fixed positional for parameters. It is possible to write something like
%3$*1$.*2$d (which happens to be the same as %*.*d).
* Fixed precision of integers.
* Fixed parameter flags. Before trio could only handle one parameter flag per
specifier, although two (three with double-dot base) were possible.
* Fixed isinf() for those platforms where it is unimplemented.
Version 0.18 - 2000/05/27
-------------------------
* Rewrote the entire floating-point formatting function (Danny Dulai had
reported several errors and even supplied some patches, which unfortunately
were lost due to the refactoring).
* Removed the use of strlen() in the declaration of a stack array. This
caused problems on some compilers (besides it isn't really ANSI C compliant
anyways). Using some arbitrarily chosen maximum value; should examine if
some standard defines an upper limit on the length of decimal-point and
thousands-separator (sizeof(wchar_t) perhaps?)
* Changed the parsing of the format string to be multibyte aware.
Version 0.17 - 2000/05/19
-------------------------
* Added INF, -INF, and NAN for floating-point numbers.
* Fixed %#.9g -- alternative with precision.
* Ken Gibson
Fixed printing of negative hex numbers
* Joerg (last name unknown)
Fixed convertion of non-ASCII characters
Version 0.16 - 1999/08/06
-------------------------
* Changed the constness of the second argument of StrFloat and StrDouble. The
lack of parameter overloading in C is the reason for the strange use of
constness in strtof and strtod.
* Cleaned up constness.
Version 0.15 - 1999/07/23
-------------------------
* Fixed the internal representation of numbers from signed to unsigned. Signed
numbers posed a problem for large unsigned numbers (reported by Tero)
* Fixed a tiny bug in trio_vsprintfcat
* Changed the meaning of the max argument of StrAppendMax to be consistant
with StrFormatAppendMax. Now it is the maximal size of the entire target
buffer, not just the appended size. This makes it easier to avoid buffer
overflows (requested by Tero)
Version 0.14 - 1999/05/16
-------------------------
* Added size_t support (just waiting for a C99 compliant compiler to add
ptrdiff_t and intmax_t)
* Rewrote TrioOutStreamDouble so it does not use the libc sprintf to emulate
floating-point anylonger.
* Fixed width, precision, and adjustment for numbers and doubles.
Version 0.13 - 1999/05/06
-------------------------
* Fixed zero padding for %d. Now %d will only zero pad if explicitly requested
to do so with the 0 flag (reported by Tero).
* Fixed an incorrect while() condition in TrioGetString (reported by Tero).
Version 0.12 - 1999/04/19
-------------------------
* Fixed incorrect zero padding of pointers
* Added StrHash with STRIO_HASH_PLAIN
* Added StrFormatDateMax
Version 0.11 - 1999/03/25
-------------------------
* Made it compile under cygwin
* Fixed a bug were TrioPreprocess would return an error if no formatting chars
were found (reported by Tero).
Version - 1999/03/19
--------------------
* Added trio_strerror and TRIO_ERROR_NAME.
* Changed the error codes to be positive (as errno)
* Fixed two reads of uninitialized memory reported by Purify
* Added binary specifiers 'b' and 'B' (like SCO.) ThousandSeparator can be
used to separate nibbles (4 bit)
* Renamed all Internal* functions to Trio*, which seems like a better
namespace (even though it is of no practical interest because these
functions are not visible beyond the scope of this file.)
Version - 1999/03/12
--------------------
* Added hex-float format for StrToDouble
* Double references and gaps in the arguments are not allowed (for the %n$
format) and in both cases an error code is returned.
* Added StrToDouble (and StrToFloat)
Version - 1999/03/08
--------------------
* Added InStream and OutStream to the trio_T structure.
* Started work on TrioScan.
* Return values for errors changed. Two macros to unpack the error code has
been added to the header.
* Shortshort (hh) flag added.
* %#s also quotes the quote-char now.
* Removed the 'errorInFormat' boolean, which isn't used anymore after the
functions bail out with an error instead.
Version - 1999/03/04
--------------------
* More than MAX_PARAMETERS parametes will now cause the TrioPreprocess()
function to return error.
* Unknown flags and/or specifiers cause errors too.
* Added trio_snprintfcat and trio_vsnprintfcat and the defined name
StrFormatAppendMax. They append a formatted string to the end of a string.
* Define MAX_PARAMETERS to 128 at all times instead of using NL_ARGMAX when
that exists.
* Added platform fixes for Amiga as suggested by Tero J<>nk<6E> <tesaja@utu.fi>
Version - 1999/01/31
--------------------
* vaprintf did add a zero byte even when it had failed.
* Cleaned up the code for locale handling and thousand separator
* Added trio_aprintf() and trio_vaprintf(). They return an allocated string.
* Added thousands separator for numbers
* Added floating point support for *printf
Version - 1998/10/20
--------------------
* StrMatchCase() called StrMatch() instead of itself recursively
* Rewrote the implementation of *printf and *scanf and put all the code in
this file. Extended qualifiers and qualifiers from other standards were
added.
* Added StrSpanFunction, StrToLong, and StrToUnsignedLong
Version - 1998/05/23
--------------------
* Made the StrEqual* functions resistant to NULL pointers
* Turns out strdup() is no standard at all, and some platforms (I seem to
recall HP-UX) has problems with it. Made our own StrDuplicate() instead.
* Added StrFormat() and StrFormatMax() to serve as sprintf() and snprintf()
respectively.
