+TODO (known issues):
+- Fix expansion of macros, which replacement-list terminates in a partial
+ macro expansion.
+- Try to remove the second parameter from the pp_iterator<>::force_include
+ function.
+- Fix the trigraph backslash problem in the re2c (C/C++ and IDL) scanners, if
+ there is the end of the (internal) buffer just in between a '??/' and a '\n'.

+-------------------------------------------------------------------------------
+
+CHANGELOG
+
+Boost V1.73:
+ - Fixed TRAC #7822: waveidl sample does not use the IDL lexer
+ - Fixed TRAC #9874: Turning off 'include_next' support breaks include
+ - Fixed a typedef shadowing a class (MSVC warning 4458) - Conrad Poelman
+ - Updated waveidl to match recent changes in the RE2C lexer
+ - Samples now build cleanly
+ - Ensured samples and wave driver are covered by continuous integration
+
+Boost V1.55:
+ - Fixed #8848: Wave driver improperly processes 0xFFFFui64 token
+ - Fixed #9098: Wave driver option --c++0x invalid
+
+Boost V1.54:
+ - Fixed #8478: Make Boost.wave compatible with Clang's -Wimplicit-fallthrough
+ diagnostic.
+
+Boost V1.53:
+ - Fixed a problem with context<>::add_macro_definition which sometimes
+ appended a superfluous T_EOF to the macro replacement list.
+
+Boost V1.52.0:
+ - Added util::create_directories() wrapper to account for new behavior of
+ boost::filesystem::create_directories().
+ - Fixed an obscure problem when preprocessing directives wouldn't be recognized
+ if the previous line contained nothing but an empty macro invocation
+ (see new test case t_9_023.cpp)
+ - Added a new command line option --license=<file> to the Wave driver tool
+ which allows to pre-pend the content of a (license) file to every newly
+ created file. This option simplifies the implementation of partial
+ preprocessing as done on Phoenix, Fusion, etc.
+ - Changed the effect of the -N command line option to simply not expand
+ the macro by pretending it was not defined. Earlier the whole invocation
+ sequence was skipped, now we skip only the macro itself, which still expands
+ the arguments for the macro invocation.
+ - Fixed a couple of compilation warnings
+
+Boost V1.51.0
+ - Fixed #7050: Invalid memory write bug in lexing_exception
+ - Fixed #7159: Text-lines are processed as if they were preprocessing directives
+ - Changed --c++0x command line option to --c++11.
+
+Boost V1.50.0
+ - V2.3.2
+ - Fixed #6758: not all members are initialized by base_iteration_context
+ constructor.
+ - Fixed #6838: Adding include file with force_include makes Wave fail to emit
+ #line directive
+ - Added support for test of --forceinclude option to testwave executable,
+ added test case verifying #6838 is fixed.
+ - Fixed #6870: build wave driver failed
+
+Boost V1.48.0
+ - V2.3.1
+ - Added the flag support_option_emit_contnewlines allowing to control whether
+ backslash newline sequences are emitted by the Wave library. The default is
+ as before: these tokens will be silently ignored (after the token positions
+ have been properly updated). Note: this option is supported by the SLex lexer
+ module only.
+ - Fixed #5887: flex_string.hpp needs to include <ios>
+
+Boost V1.47.0
+- V2.3.0
+- After preprocessing the body of any #pragma wave option() the wave tool now
+ concatenates all adjacent string literals into a single string literal.
+- Fixed whitespace handling, added a corresponding set of test cases
+ (t_9_020.cpp)
+- Added a new preprocessing hook: locate_include_file allowing to customize the
+ way include files are located.
+- Added new command line option --noexpand/-N to the Wave driver allowing to
+ suppress macro expansion for a given macro name (works for both, object like
+ and function like macros). This option has to be used very carefully as it
+ not only leaves the whole macro invocation untouched in the generated output
+ but also removes this macro from consideration for Wave itself. This can
+ cause unexpected results if the suppressed macro would influence #ifdef's
+ later on.
+- Fixed Wave driver to retain all macros defined on the command line in
+ interactive mode.
+- Fixed problem #5554: wave slex parser eof without eol skips the last line.
+- Added the compile time configuartion option BOOST_WAVE_WCHAR_T_SIGNEDNESS,
+ which can be set to BOOST_WAVE_WCHAR_T_AUTOSELECT, BOOST_WAVE_WCHAR_T_FORCE_SIGNED,
+ or BOOST_WAVE_WCHAR_T_FORCE_UNSIGNED), it defaults to autoßselect.
+- Fixed a problem in teh wave driver tool related to #pragma option(output).
+ If wave was invoked in rapid succession this erroneously appended to an
+ existing file instead of overwriting that file.
+- Fixed #5569: slex CONTLINE token works only for LF line endings
+
+Boost V1.46.0
+- V2.2.0
+- Added recognition of C++0x keywords to Re2C lexers.
+- Added --c++0x command line option to Wave to enabling the recognition of
+ C++0x keywords, converting those to C++0x tokens.
+- Adapted all of the library to play well with Boost.Filesystem V3 (which is
+ the default from now on).
+- Added support for extended character and string literals, added test case
+ (which required to add C++0x support to the test application).
+- Added proper predefined macros fro --c++0x mode. __cplusplus is currently
+ defined to 201101L, but this will change when the Standard is finalized.
+- Fixed a problem with object like macros, which when being adjacent to a
+ parenthesis, caused the parenthesis to disappear when the macro expansion
+ was suppressed by the expanding_object_like_macro() hook function.
+- Fixed a bug in pragma option(preserve), missing to set to preserve=1 if
+ after the previous value was preserve=2.
+- Changed the --preserve option of the wave tool to interprete the integer
+ argument in a slightly different way:
+ 0: no whitespace is preserved,
+ 1: only begin of line whitespace is preserved,
+ 2: only begin of line whitespace and comments are preserved,
+ 3: all whitespace is preserved
+ The #pragma wave option(preserve) now supports these arguments:
+ [0|1|2|3|push|pop].
+
+Boost V1.45.0
+- V2.1.0
+- Token pasting is well formed only as long as the formed token(s) are
+ pp_tokens as defined by the C++0x Standard. Until now, Wave allowed for
+ non-pp_tokens to be formed in --variadics mode.
+- Fixed a problem, which prevented reporting /##/ in a macro definition as
+ invalid token pasting.
+- Fixed problem preventing the skipped_token hook to be called for 'inactive'
+ conditional preprocessing directive tokens. Improved overall consistency in
+ reporting skipped tokens to the hooks function when processing conditional
+ preprocessing directives. Added a new test case verifying the skipped_token
+ hook gets called reproducibly (t_2_020.cpp).
+- Fixed a problem with the pp hooks 'expanding_object_like_macro' and
+ 'expanding_function_like_macro', which when returning true were stopping all
+ preprocessing instead of just inhibiting the expansion of the macro.
+- Fixed a duplicated call to the pp hook skipped_token for preprocessing
+ directives inside inactive conditional branches.
+- Changing exception handling to fix clang++ regression errors.
+- Replaced assert() with BOOST_ASSERT to pacify the Boost inspect tool.
+
+Boost V1.44.0
+- V2.0.6
+- Added information about the file type to iteration context. This can be
+ either main_file, system_header, or user_header depending whether the handled
+ file is the main file to preprocess, a include file opened from `#include <>`,
+ or a include file opened from `#include ""`.
+- Added support for new Boost visibility macros. Properly exported all
+ exceptions, etc.
+
+Boost V1.43.0
+- V2.0.5
+- Fixed the wave driver application to strip leading and trailing whitespace
+ from macro names specified on the command line using -U.
+- Fixed line number counting for lines containing nothing but whitespace
+ followed by a C++ comment if the next line is a pp directive.
+- Fixed emitting of a #line directive after returned from an include file.
+- A couple of fixes allowing to properly report the current line number in
+ #line directives for different whitespace preserve modes (see --preserve/-p).
+- Added new preprocessing hook: emit_line_directive, allowing to customize the
+ format of the generated #line directive.
+- Changed --line/-l command line option of the wave driver application to
+ accept 0, 1, and 2 as options. The option values 0 and 1 behave as before
+ (disable/enable the generation of #line directives), while the option value 2
+ will generate the #line directive using the relative filename (instead of the
+ absolute filename emitted from option 1). The default option is value 1.
+- Added new example: emit_custom_line_directives, demonstrating the use of the
+ new preprocessing hook.
+- Added new preprocessing hook: found_unknown_directive, which is being invoked
+ whenever an unknown preprocessor directive (i.e. '#' followed by some
+ identifier) is detected. It allows to interpret the directive and to provide
+ some replacement text.
+- Added new example: custom_directives demonstrating the usage of the new
+ preprocessing hook.
+- Fixed #4113: cpp_lexer does not handle qualified backslashes correctly.
+- Fixed #3106: wave on VS2010 beta compiler generates error.
+
+Boost V1.42.0
+- V2.0.4
+- Fixed Wave for latest changes in multi_pass iterator.
+
+Boost V1.41.0
+- V2.0.3
+- Switched to Re2C V0.13.5
+- Fixed --list_includes/-l command line option of the wave driver tool to
+ correctly indent the generated list of included files.
+- Finally fixed all remaining examples. Everything seems to work fine now.
+- Specifying a custom token type now works as expected. The new lexer interface
+ introduced in V2.0 broke this part.
+- Removed old code related to pre Boost V1.31 (related to V1 of iterator
+ library).
+- Added a new commandline option --macrocounts/-c to the Wave driver application
+ which lists all macro invocation counts to an optionally specified file
+ (default is cout).
+- Fixed compilation problems caused by recent changes to the multi_pass iterator
+ from Spirit V2.1.
+- Added the new preprocessing hooks detected_pragma_once() and
+ detected_include_guard() which are getting called whenever either a #pragma
+ once has been detected or if the include guard heuristics detected an
+ include guard for a particular include file.
+- Added a new command line option to the wave driver tool: --listguards/-g
+ allowing to trace all include files which are either contain a #pragma once
+ or contain include guards.
+- Started to elminate g++ struct aliasing warnings (more to fix, mostly in
+ flex_string).
+
+Boost V1.40.0
+- V2.0.2
+- Fixed a long standing race condition inhibiting to use Wave in multi threaded
+ environments.
+- Incorporated the changes from latest version of the flex_string class (#2946).
+- Fixed another race condition triggering problems using Wave in multi-threaded
+ environments.
+
+Boost V1.39.0
+- V2.0.1
+- Fixed Wave to compile with BOOST_FILESYSTEM_NO_DEPRECATED defined (i.e. the
+ library doesn't use the deprecated filesystem interface anymore).
+
+Boost V1.37.0
+- Updated examples to reflect the recent changes in the used multi_pass
+ iterator.
+- Fixed documentation links still pointing to the old Boost CVS (thanks to
+ Jürgen Hunold for providing the patch).
+
+Boost V1.36.0
+- Wave Version 2.0 is a new major release introducing some breaking API changes,
+ preventing it to be used with Boost versions earlier than V1.36.0. The API
+ and hook interface have been streamlined for more consistency. See the
+ documentation for more details.
+
+- Added an additional template parameter to the context object, allowing to
+ specify any possibly derived type. This change propagates to the preprocessing
+ hooks, which now get passed the most derived context type as its first
+ argument allowing to access protected members in the original context type.
+ This fixes ticket #1752.
+- Fixed a problem during parsing of #pragma wave directive, where the value
+ sequence contained a closing parenthesis. This caused a premature end of the
+ pragma value parsing.
+- Fixed handling of support_option_single_line, which was ignored under certain
+ circumstances.
+- Fixed ticket #1766: Wrong evaluation of conditional preprocessor directives
+ with predefined macros __FILE__, __LINE__ and __INCLUDE_LEVEL__. This bug
+ triggered an error in constructs like #ifndef __FILE__. Thanks to Daniel
+ Wadehn for reporting and supplying a patch. Added corresponding regression
+ test: t_2_018.cpp.
+- Fixed a bug which reported a valid macro redefinition as invalid if the macro
+ replacement text referred to a second or higher parameter of this macro.
+- Fixed a problem in the wave tool to allow two errors to occur while
+ preprocessing two consecutive tokens.
+- Adjusted Spirit header includes to point to conform to the new directory
+ structure, removed support for Spirit versions earlier than V1.7.
+- Started to migrate to new multi_pass iterators from Spirit V2.0.
+
+Boost V1.35.0
+- Wave Version 1.3
+- Changed the return value of the 'evaluated_conditional_expression()' pp hook
+ to 'bool' allowing to force Wave to re-evaluate the current conditional
+ expression. This was suggested by Felipe Magno de Almeida.
+- Added a wave::context object as first parameter to all pp hook functions.
+ This is an interface compatibility breaking change. The new pp-hooks can be
+ disabled by defining the BOOST_WAVE_USE_DEPRECIATED_PREPROCESSING_HOOKS
+ compile time constant to something not equal to zero. By default this
+ constant will be defined to zero for Boost V1.35.0 and newer, switching to
+ the new interface by default.
+- Added optional support for the import keyword (needed for the C++ module
+ proposal). The identifier import will be recognized as a keyword, if
+ the compile time constant BOOST_WAVE_SUPPORT_IMPORT_KEYWORD is defined to
+ something not equal zero.
+- Added new preprocessing hook functions: found_error_directive() and
+ found_warning_directive() to be called when #error/#warning directives are
+ encountered. This was suggested by Andreas Sæbjørnsen.
+- Added a new sample to Wave: hannibal, a partial C++ parser implementation
+ initially written by Danny Havenith (http://havenith-verlinden.nl/hannibal/)
+ who agreed to add this here. Thanks!
+- Added new preprocessing hook function: found_line_directive() to be called
+ when a #line directive is encountered. This was suggested by Andreas
+ Sæbjørnsen.
+- Improved command line handling for the wave applet.
+- Incorporated latest bug fixes for the Hannibal sample provided by Danny
+ Havenith.
+- Added loading of a wave.cfg file from anywhere up the filesystem hierarchy
+ starting from the main input file for the wave driver applet up to the
+ root of the file system.
+- Added support_option_emit_pragma_directive to allow to control at runtime,
+ whether unknown #pragma directives should be emitted or not. To maintain
+ compatibility with earlier versions this option is by default on if the
+ compile time constant BOOST_WAVE_EMIT_PRAGMA_DIRECTIVES was defined to
+ be not equal to zero and it is off otherwise.
+- Enabled XML serialization support.
+- Added the throw_exception preprocessing hook, which gets called for every
+ occurring error (whenever an exception would have been thrown). The default
+ of this new hook function is to throw the corresponding exception, which
+ reproduces the old behavior.
+- Implemented a new preprocessing hook: generated_token(), which get's called
+ whenever a token is about to be returned form the library. This function may
+ be used to alter the token before it gets returned to the calling
+ application.
+- Added a new sample 'real_positions' demonstrating the new generated_token()
+ preprocessing hook and showing how to use Wave with a new token type without
+ using a new lexer type.
+- Factored out the pure lex_input_interface to simplify writing different lexer
+ types for Wave.
+- Added the token_statistics sample showing how to use Xpressive to build a
+ lexer for Wave.
+- Changed the list_includes sample to use a lexer which is based on the lexertl
+ library written by Ben Hanson (http://www.benhanson.net/lexertl.html).
+- Added a new support_option: insert_whitespace, allowing to switch off
+ whitespace insertion which is normally (by default) in place to disambiugate
+ C++ tokens, which would otherwise form different tokens in the output.
+- Added a new commandline option to the Wave applet: --disambiguate, allowing
+ to control whitespace insertion. The default value for this option is
+ --disambiguate=1, resembling the previous behaviour. Specifying the option
+ --disambiguate=0 allows to suppress whitespace insertion alltogether.
+- Added pragma option values push and pop to the line, preserve and output
+ options allowing to store and restore the current option. The syntax is:
+ #pragma wave options(<option>: push) and
+ #pragma wave options(<option>: pop)
+ where <option> may be line, preserve or output. Thanks to Eric Niebler for
+ suggesting this feature.
+- Added the possibility to use static pre-compiled DFA tables for the lexertl
+ based lexer.
+- Incorporated the changes from Andrei's latest version of the flex_string
+ class.
+- Added the is_macro_defined(name) function to the context object as described
+ in the documentation. This function is usable with any string type compatible
+ with std::string.
+- Changed behavior of the --force_include functionality, which now looks for
+ the file to be (force-)included in the current directory first.
+- Switched to Re2C V0.11.2
+- Added const specifiers to some of the context member functions.
+- Fixed a problem in the SLex C++ lexer (cpp_tokens example).
+- Fixed a runtime problem in the Re2C generated lexers when feeded with
+ empty input files (thanks to Leo Davis for reporting and providing a patch).
+- Added the is_eoi() function to token classes, returning true if the token
+ has been initialized to be the end of input token (T_EOI) (thanks to Ovanes
+ Markarian for suggesting this).
+- Added missing #includes <cstring>, <cstdlib>, and <new> to flex_string.hpp.
+- Added missing #include <climits> to cpp_chlit_grammar.hpp.
+- Changed found_include_directive hook function to return a bool indicating,
+ whether the file should be included (true) or skipped (false). Thanks to
+ Felipe Magno de Almeida for suggesting this feature.
+- Added code to the wave driver applet ignoring a #import directive (the whole
+ directive is passed through to the output) whenever the pp constant
+ BOOST_WAVE_SUPPORT_MS_EXTENSIONS is defined to something not equal to zero.
+- Fixed the wave driver applet to correctly continue after a error or warning.
+- Added a macro introspection facility allowing to iterate on all defined macro
+ names.
+- Added a new commandline option --macronames/-m to the Wave driver application
+ which lists all defined macros and their definitions to an optionally
+ specified file (default is cout).
+- Fixed configuration to take into account thread related build settings.
+- Added the BOOST_WAVE_SUPPORT_LONGLONG_INTEGER_LITERALS pp constant allowing
+ to recognize large integer literals (larger in size than long/unsigned long)
+ even if these do not have a 'll' suffix. This pp constant is effective only,
+ if the target platform supports long long integers (BOOST_HAS_LONG_LONG is
+ defined).
+- The following preprocessing hooks now return a boolean value, which when
+ returning 'true' cause the Wave library to skip the execution of the related
+ preprocessing action:
+ . found_directive: allows to skip the whole directive it is called for
+ . expanding_object_like_macro: allows to skip expansion of the given object
+ like macro, the macro symbol is copied to the output
+ . expanding_function_like_macro: allows to skip the expansion of the given
+ function like macro, the whole macro invocation (including all
+ macro invocation parameters) are copied to the output without any
+ further processing.
+- Changed the interpretation of the return value of the found_include_directive
+ preprocessing hook: a return value of 'false' now processes the file
+ to be included normally and a return value of 'true' now skips the processing
+ of the include file directive (the file doesn't get included).
+ This change was necessary to make the return values of the preprocessing
+ hooks consistent. Now return 'false' generally means: normal execution and
+ return 'true' generally means: skip execution of the corresponding
+ preprocessor action.
+- Fixed compilation problems on gcc, fixed ambiguity with boost code (detail
+ namespace was ambigious).
+- Fixed predefined macro support to be thread safe.
+- Added missing file to real_positions example. Thanks to Ludovic Aubert for
+ spotting the problem.
+- Unterminated C++/C comment diagnostics are now a warning and not an error
+ anymore.
+- Applied patch provided by Jens Seidel making sure every header compiles on
+ its own.
+- Updates to the documentation.
+- Fixed a problem in flex_string::compare() (#include_next was non-functional).
+- Fixed a bug in the pp hook expanding_function_like_macro(), where the seqend
+ parameter was set to the first token after the closing parenthesis instead of
+ pointing at it.
+- Added the BOOST_WAVE_SUPPORT_THREADING allowing to explicitely control
+ whether the Wave library is built with threading support enabled. If not
+ defined the build settings will be picked up from the Boost build environment
+ (BOOST_HAS_THREADS).
+- Fixed a whitespace insertion glitch, where whitespace got inserted
+ unconditionally between two operators even if one of these was a comma.
+- Fixed #line directive after a macro invocation containing newlines to
+ correctly reference the line number.
+- Positions of macros defined on the command line now get properly reported as
+ "<command line>":1:...
+- Added testing of the preprocessor hooks.
+
+Boost V1.34.0
+- Wave Version 1.2.4
+- Added the possibility to explicitly enable/disable the generation of #line
+ directives. Added a corresponding commandline argument to the Wave driver
+ tool (--line/-L) which takes either 0 or 1 as its parameter.
+- Added support for #pragma wave option(command: value) directives, which
+ supports the following commands:
+ . #pragma wave option(line: [0|1])
+ Enable/disable generation of #line directives
+ . #pragma wave option(preserve: [0|1|2])
+ Control whitespace preservation
+ . #pragma wave option(output: ["filename" | null | default])
+ Redirect output to the given file (or no output, if 'null' is specified,
+ or output to the file as given on the command line, if 'default' is
+ specified).
+ The filename is resolved relative to the directory of the processed
+ file.
+ These new #pragma directives are implemented in the Wave driver tool only.
+ It is possible to combine several options in one #pragma directive, i.e.
+ #pragma wave option(line: 0, preserve: 2).
+- Changed the signature of the may_skip_whitespace() preprocessing hook to
+ additionally take the preprocessing context as its first parameter.
+- Added the possibility to the Wave tool to disable initial output by
+ specifying a '-' as the output file. This is useful for syntax checks only or
+ in conjunction with the #pragma wave option(output: ...) to restrict the
+ generated output.
+- Improved error reporting in the Wave tool on bad output file stream state.
+- Switched to Re2C V0.10.0
+- Fixed some of the VC7.1 /W4 warnings.
+- The Wave tool now creates the directory hierarchy of output files as needed.
+- Applied some optimization, which causes skipping of the parsing for almost
+ all preprocessor directives when the if block status is false. This gains
+ upto 10-20% in speed for average applications.
+- Added error diagnostic for #elif without matching #if, which was missing
+ under certain circumstances.
+- Avoided the evaluation of #elif expressions if one of the previous #if/#elif
+ blocks of the same level was true. This gains upto another 5% of speed for
+ average applications.
+- The MS specific integer suffix 'i64' is now correctly supported by the Re2C
+ and SLex lexer components (only when BOOST_WAVE_SUPPORT_MS_EXTENSIONS is
+ defined during compilation).
+- Changed the Wave tool to print the column number of an error/warning along
+ with the line number. The new format is: 'filename:line:column: error text'.
+- It is now possible to recover from the unbalanced #if/#endif statement
+ warning in a proper way.
+- The Wave library now automaticaly recognizes include guards in headers files
+ and uses this information to avoid opening these header files more than once.
+ This speeds up things by upto 10-20% depending on the concrete include files.
+- Fixed the failing test t_6_023.cpp. Error reporting for illformed #else
+ directives was broken (because of some recent changes).
+- Fixed the failing test t_5_007.cpp. This was caused by the automatic include
+ guard detection, which prevented the second inclusion of the specified
+ include file the test was relying on.
+- Added the possibility to switch off the automatic include guard detection.
+- Added a new command line option to the Wave tool: --noguard/-G, which
+ disables the automatic include guard detection.
+- Now a header with include guards will be included correctly for a second time
+ after its include guard symbol gets undefined.
+- Added the generating platform to Wave's full version string.
+- Made the Wave tool fully interactive when started with input from stdin and
+ and output to stdout. In this mode the Wave tool preprocesses the input
+ line by line and not only after receiving the full input as normally.
+- Added serialization support for the wave::context object, which stores
+ all information about defined macros and all #pragma once header information.
+- Added the command line option --state (-s) to the Wave tool, which tries to
+ load the serialized information from the file given as the argument to
+ --state and save the state information at the end to the same file.
+ This option is available in interactive mode only.
+- Added possibility to verify the compatibility of the configuration used
+ during compilation of the Wave library with the config info used for the
+ application. Added a corresponding test to the Wave tool.
+- Added a new predefined macro __WAVE_CONFIG__ which expands to an integer
+ literal containg the configuration information the library was compiled
+ with.
+- Added proper versioning support to the serialization of state.
+- Fixed the macro tracing information to contain the column numbers of the macro
+ definitions as well (the format used is the same as for error messages).
+- Fixed a memory leak in the flex_string copy on write code (thanks to Tobias
+ Schwinger for reporting this bug).
+- Fixed a memory corruption bug in the Re2C scanner buffer management code
+ (thanks to Andreas Sæbjørnsen for spotting the bug).
+- Fixed a major performance bottleneck in the lex_token class. This speeds up
+ Wave for upto another 20-40% depending on the amount of macro expansions to
+ perform.
+- Added the BOOST_SPIRIT_USE_BOOST_ALLOCATOR_FOR_TREES and the
+ BOOST_SPIRIT_USE_LIST_FOR_TREES Spirit configration constants to the
+ wave_config.hpp to allow to fine tune the generated Spirit tree code. VC7.1
+ gives best results when both are defined.
+- Fixed a memory corruption bug triggered by a possible dangling reference.
+- Fixed Wave tools startup crash when compiled with VC8.
+- Added the name of the generating compiler (BOOST_COMPILER) to the full
+ Wave version info.
+- Fixed all Jamfile.v2 to correctly disable RTTI for VC7.1.
+- Added #pragma message("...") to be optionally supported by the Wave library.
+ This may be enabled by defining the BOOST_WAVE_SUPPORT_PRAGMA_MESSAGE pp
+ constant to some value different from zero.
+- Fixed a couple of typos in the file cpp.cpp preventing it to compile on
+ gcc 4.1.0 (thanks to Richard Guenther for reporting these).
+- Richard Guenther fixed another buffer overrun problem in the Re2C scanner.
+- Fixed Jamfile.v2 files for all sample applications.
+- Fixed a bug which lead to reporting of an illegal preprocessing directive
+ inside not-evaluated conditional blocks under certain circumstances (thanks
+ to Tobias Schwinger for reporting).
+- Fixed '#define true ...', '#define false ...' and other constructs, i.e. the
+ usage of the boolean keywords as identifiers during the preprocessing. Added
+ a corresponding test case (t_9_017.cpp). Thanks to Andreas Sæbjørnsen for
+ reporting.
+- Corrected the Jamfile[.v2] of the waveidl sample to refer to correct file
+ names (thanks to Juergen Hunold for submitting a patch).
+- Fixed a bug which prevented the main iterator from returning a T_EOF token
+ at the overall end of the input.
+- Fixed a problem, where non-evaluated #elif directives never got passed to the
+ skippen_token() pp hook (thanks to Andreas Sæbjørnsen for reporting).
+- Fixed a problem in the get_tokenname() function.
+- Added a missing #define BOOST_WAVE_SOURCE 1 to the wave_config_constant.cpp
+ file.
+- Fixed exception specifications to catch all exceptions by const&.
+- Fixed predefined macros to appear to be defined at a position referring to
+ a file named "<built-in>". Thanks to Andreas Sæbjørnsen for reporting.
+- Fixed the Re2C lexer not to segfault on empty files anymore.
+- Stripped leading and trailing whitespace for all lines in a config file (Wave
+ driver tool).
+- Fixed RTTI build issue for VC7.1/bjam --v2 (thanks to Rene Rivera for
+ submitting a patch for the Wave Jamfile.v2).
+- Fixed certain problems reported by the Boost inspection tool.
+- Fixed a couple of SunPro5.8 warnings.
+- Fixed a bug resulting in a crash if a macro was redefined with a shorter
+ expansion list as it was defined initially. Added a corresponding test case.
+- Fixed a bug causing an infinite loop when there was a missing endif in the
+ main preprocessed file.
+- Improved error recovery for illegal preprocessing directive errors.
+- Improved error handling and error recovery for conditional expressions
+ (#if/#elif expressions).
+- Wave now passes 160 out of 161 tests from the MCPP V2.6.1 validation
+ testsuite!
+- Added new warning for invalid #line number and filename arguments
+- Improved error diagnostics for invalid #line directives containing arbitrary
+ tokens after at the end of the line.
+- Improved error handling wrt the misuse of the __VA_ARG__ token in macro
+ definitions.
+- The warning, that a file is not terminated by a newline is now issued for all
+ files, not only for the main file (as previous).
+- Added a couple of new test cases to verify various diagnostics.
+- Fixed wave applet not to report missing #endif's when in interactive mode.
+- Cleaned up the Re2C lexer code.
+- Fixed a bug, where a empty line followed by an arbitrary token and followed
+ by a preprocessing directive interpreted the preprcessing directive as if it
+ were the first non-whitespace token on the line. This error occurred only
+ if the #line directive generation was suppressed. Thanks to Joan Grant for
+ reporting this problem.
+- Fixed a problem in the Wave applet which prevented the correct recognition of
+ Windows file paths in a configuration file, if this path was enclosed in
+ quotes.
+- Extended the copyright notice to include the year 2007.
+- Fixed a problem in preserve=1 mode, when a C style comment triggered the
+ generation of a #line directive.
+- Worked around a linker issue for the True64/CXX compiler, complaining about
+ multiple defined symbols when using the flex_string class.
+- Added missing documentation for the context::get_macro_definition function.
+
+Sat Feb 18 2005
+- Version 1.2.3
+- Added a missing throw() specification to the function
+ cpp_exception::get_related_name().
+- Fix Boost bug ([ boost-Bugs-1395857 ] wave redefines BSIZE).
+- Added missing calls to the skipped_token() preprocessing hook which wasn't
+ called for pp directives inside disabled #if blocks.
+- Made the context<> type noncopyable.
+- Introduced the --extended/-x command line option to the wave driver
+ executable, which enables the #pragma wave system() directive. This directive
+ is now disabled by default because it may cause a potential security threat.
+- Changed the what() function of the macro_handling_exception class, which now
+ correctly returns the name of the exception type itself.
+- Added a diagnostic message to the wave driver executable, which is issued
+ whenever a #pragma wave system() directive is found, but the -x (--extended)
+ command line argument was not given.
+- Fixed long integer suffix to be allowed to be mixed case (1Ll or 2lL).
+- Fixed the BOOST_PP_CAT(1e, -1) pp-token bug. Wave now correctly recognizes
+ pp-number tokens, which are converted to C++ tokens right before they are
+ returned from the library.
+- Moved the implementation of the token_id query functions (get_token_name(),
+ get_token_value()) to a separate source file.
+- Fixed a bug, which prevented to prefer pp-numbers in files preprocessed as
+ a result of #include directives.
+- Fixed a bug, which prevented to open #include'd files specified by an
+ absolute path.
+- Fixed a problem in the expression parser value type.
+- Fixed a dynaload compilation problem with VC7.1 of the re2c lexer tests.
+
+Sat Dec 24 13:33:53 CST 2005
+- Version 1.2.2
+- Added three new preprocessing hooks: 'found_directive', 'skipped_token' and
+ 'evaluated_conditional_expression' (thanks to Andreas Sæbjørnsen for the
+ suggestions).
+- Removed hook forwarding functions in the context_type.
+- Added missing include_next case branches for get_directivename() function.
+- Added new sample: advanced_hooks.
+- Fixed a possible buffer overflow in the cpplexer and cpp exception classes.
+- Made the cpp_grammar thread safe.
+- Removed the need for the get_directivename() function. Fixed typos in the
+ predefined token table.
+- Removed assertions from get_token_name() and get_token_value() and replaced
+ these with more meaningful code.
+- Added the BOOST_WAVE_USE_STRICT_LEXER configuration constant which allows to
+ decide, whether the '$' character will be recognized as a part of identifiers
+ or not (the default is BOOST_WAVE_USE_STRICT_LEXER == 0, i.e. '$' will be
+ recognized as part of identifiers).
+- Added the possibility to testwave to extract a tagged comment based on a
+ preprocessor constant (testwave V0.4.0).
+- Made the predefined_macros_grammar thread safe.
+- Added dll support for the generated Wave libraries.
+- Added the const_iterator based exlicit instantiations for the Re2C lexer to
+ the built Wave library and dll.
+- Added the whitespace handling policy to the context object. This actually is
+ no separate policy, it's a new preprocessing hook allowing to decide, whether
+ a concrete token has to be skipped.
+- Changed the --preserve option of the wave tool to take a single integer
+ argument (0: no whitespace is preserved, 1: only comments are preserved,
+ 2: all whitespace is preserved)
+- Edited the command line option descriptions of the wave driver.
+- Fixed broken tags in documentation (magically inserted by DreamWeaver).
+- Merged the new whitespace_handling policy with the existing preprocessing
+ hooks. The name of the new preprocessing hook ist may_skip_whitespace().
+- Fixed compatibility issues for CW9.4 in the Wave test aplication.
+- Added get_errorcode() member to the wave exception classes allowing to
+ get back the reason for the exception.
+- Added boost::wave::is_recoverable(cpp_exception const&) alowing to decide,
+ whether it is possible to continue after a cpp_exception has been thrown.
+ This is a temporary hack to overcome the current limitation of the library
+ not allowing to do generic error recovery. It allows to recover from 75% of
+ the generated errors types.
+- The --timer command line option for the Wave driver now prints the elapsed
+ time correctly even if a preprcessing error occurred.
+- Fixed an error recovery problem which skipped one token after continuing in
+ case this was a pp directive.
+- Added the --autooutput (-E) option to the Wave driver applet which redirects
+ the generated output to a file named after the input file changing the file
+ extension to '.i'.
+- Changed all throw's to boost::throw_exception.
+- Added the possibility to configure the command keyword for the wave specific
+ #pragma directives. It is now possible to define a string literal via
+ BOOST_WAVE_PRAGMA_COMMAND, which will be recognized and all corresponding
+ #pragma's are dispatched to the interpret_pragma() preprocessing hook.
+ The default value for BOOST_WAVE_PRAGMA_COMMAND is "wave", just to ensure
+ complete backward compatibility.
+- Added missing #pragma warning(pop) directives.
+- Fixed a bug wrt error propagation in the expression parser.
+- Fixed an assertion fired when cpp_token is used to process the quick_start
+ sample.
+- Fixed a (Windows specific) bug which triggered a boost::file_system exception
+ under certain conditions.
+- Switched to Re2C V0.9.11
+- Fixed a problem with the new '-E' (--autooutput) option.
+- Added better error reporting for duplicate macro definitions to the Wave
+ tool. Added the macro_handling_exception type containing the corresponding
+ macro name via the new (virtual) get_related_name() function.
+- Added the get_severity() function to the exceptions thrown by the Wave
+ library.
+- Extended the copyright notice to include the year 2006.
+
+Mon Dec 5 22:05:22 CST 2005
+Boost V1.33.1
+- Version 1.2.1
+- Fixed bug reported as Sourceforge bug 1274584.
+- Switched to Re2C V0.9.9.
+- Fixed a bug where the 'parameters' and 'definition' parameters to the
+ defined_macro callback of the preprocessing hooks were always empty (thanks
+ to Stefan Seefeld for reporting).
+- Fixed missing namespace specifiers in token definition macros (thanks to
+ Jozsef Mihalicza for reporting).
+- Enabled --preserved and --long_long modes by default for the cpp_tokens
+ sample.
+- Newline tokens reported a wrong line number (offset by one) when using the
+ Re2C generated lexer (thanks to Jozsef Mihalicza for pointing this out).
+- Changed file positions to carry 'unsigned int' line and column numbers.
+- Fixed tokens of a generated #line directive to carry the correct column
+ numbers.
+- Tokens now contain the correct filename, line and column numbers even if
+ a #line directive was encountered.
+- Fixed wrong line numbering in reference comments of the tests t_5_002.cpp and
+ t_5_035.cpp.
+- Made sure, that preprocessor expression errors get ignored for 'passive'
+ #elif branches.
+- Fixed an issue reported by the gcc debug stl.
+- Added the <vc-7_1-stlport><*><rtti>off directive to all of the V1 Jamfiles.
+
+Wed Aug 17 20:21:00 CST 2005
+Boost V1.33.0
+Version 1.2
+- Fixed name clash wrt T_DIVIDE on FreeBSD.

+ it has to be enabled by the new long_long mode (default in C99).
+- Fixed compilation if BOOST_WAVE_DUMP_PARSE_TREE is defined.
+- Fixed lexer error message wrt long_long mode.
+- Stefan Seefeld fixed a bug in the lexer, where include_next was assumed for

+- Fixed some trigraph token id's in the lexers.
+- Added column information to the re2c generated lexer.
+- Added tests for the different lexers.
+- Fixed the found_include_directive preprocessing hook to carry the information

+ and to make CW8.3 happy.
+- Unified lexer interface, adjusted namespaces.
+- Added lexer testcases to the regression tests.
+- Fixed test cases to scale to 64 bit platforms.
+- Disabled the MS specific extensions in the lexer tests in a platform related
+ way.

+ for Comeau.
+- Applied a workaround proposed by David Abrahams to make the slex lexer work
+ on the CodeWarrior platforms.

+- Fixed a bug in the slex regex specifications.
+
+Thu Apr 7 10:07:45 WEDT 2005
+Version 1.1.16
+- Fixed a bug in the white space eating component, which prevented a C++
+ comment to be suppressed if it followed after another whitespace.
+- Fixed the inconsistencies between the documentation and the behaviour wrt the
+ different include search paths. See the Wave driver docs for details of how
+ the '-I', '-I-', and '-S' options work.
+- Allowed to specify more than one config file ('@' syntax) on the command line
+ of the wave driver executable.
+- Changed copyrights in all files to reflect the acceptance of Wave into Boost.
+- Unknown preprocessing directives were not recognised as such anymore.
+- If comments shouldn't be preserved all C++ comments are replaced by newline
+ tokens (instead of beeing igored completely).
+- Fixed a bug in the white space eater component.
+- Fixed a bug which reported wrong line numbers for error encountered during
+ retokenisation (concatination).
+- Fixed a bug in the unescaping code.
+- Fixed a compilation error of the testwave executable (added a missing
+ namespace specifier).
+- Added a missing header to make cpp.re.cpp compile on CW.
+- The predefined macro __BASE_FILE__ now returns a properly escaped file name
+ string.
+- Fixed the function boost::wave::util::impl::unescape_lit().
+- Added the Wave unit test framework. For now it contains about 60 unit tests
+ executed by a special test driver (testwave).
+- Added the '$F' replacement string to the testwave application. This allows
+ to handle file paths sensitive comparison of the expected and real results.
+- Fixed a minor problem in the whitespace eating component.
+- Added optional trigraph conversion.
+- Changed all size_t, time_t etc. to std::size_t, std::time_t etc (for CW).
+- If the comments should not be preserved every C comment containing at minimum
+ one newline is now converted to a newline token.
+- Added the lexed_tokens sample.
+- Fixed warnings and errors reported by the CodeWarrior compiler.
+- Added the '$V' replacement string to the testwave application. It expands to
+ the current BOOST_LIB_VERSION.
+- Diagnosed the attempt to redefine the alternative operators as and, or etc.
+- Improved error handling.
+- Disabled the flex_string class for VC7, enabled to fallback to std::string
+ for this compiler.
+- Renamed files to comply with the Boost rules.
+- Added the first part of the MCPP validation suite to the Wave unit tests.
+- Added even more missing "using namespace std;" statements for functions from
+ the C runtime library. The Wave test suite now contains more than 100 unit
+ tests.
+- Added the $P/$P(basename) replacement string to the testwave application
+ which expands to the full path of the current file ($P) or to the current
+ directory/basename ($P(basename)).
+- Fixed a bunch of portability problmes revealed by the regression tests on
+ different platforms. Thanks to Stefan Slapeda for his support to make it work
+ on the cw-9_4 toolset (win32).
+
+Tue Mar 22 14:52:45 WEST 2005
+Version 1.1.15
+- Fixed a bug where the complete set of C99 predefined macros were pre-defined
+ when in C++ mode and variadics were enabled.
+- When in variadics or C99 mode the __BASE_FILE__ predefined macro expanded to
+ <Unknown>.
+- Added the --listincludes option to the Wave driver executable which allows to
+ log the file names of the include files opened.
+- Fixed a gcc warning in token_cache.hpp (unused variable end).
+- Changed the logic behind #include_next. It now starts searching with the
+ next directory after the directory the current file (the file containing the
+ #include_next directive) is located in.
+- Changed the signature of the undefined_macro preprocessing hook to take the
+ token itself and not the macro name only. This is important to pass the full
+ context information about the position of the #undef directive to the
+ user provided hook (thanks to Stefan Seefeld for pointing that out).
+- Fixed several broken links in the Context Policy topic.
+- Fixed a bug in the handling of the #include_next directive inside of
+ non-evaluated #if blocks.
+- Fixed a bug in the #include_next handling code (thanks to Stefan Seefeld).
+- Changed the signature of the opened_include_file() preprocessing hook which
+ now receives not only the absolute file name of the openend include file but
+ additionally gets passed the (possibly) relative path of the openend include
+ file. This concrete format of the relative path depends on the format of the
+ include search directory given to the library.
+- Added a new preprocessing hook 'found_include_directive()' which gets called
+ for every #include directive (even for those where the file to include
+ doesn't exist) and which gets passed the (expanded) token sequence found
+ after the #include directive token.
+- The file names passed to the preprocessing hooks are now normalised.
+- Changed the opened_include_file() preprocessing hook to receive the correct
+ relative path even if the included file was found in the current directory.
+- Fixed a bug which reported 'defined(or)' as invalid (similarly all the other
+ alternative bit operation token types).
+- Fixed a bug which prevented to define variadic macros from the command line.
+- Added a 'preserve comments' mode to preserve the comments in the input stream
+ not inserted into macro definitions.
+- Added a new --preserve (-p) command line switch to the wave driver
+ application to allow comments to be preserved in the generated output stream.
+
+Mon Feb 21 09:30:04 WEST 2005
+Version 1.1.14 (Fixes in response to the Boost review)
+
+Wave was accepted into Boost!
+
+With special thanks to Tom Brinkman, who volunteered to be the review manager.
+
+With thanks to David Abrahams, Beman Dewes, Reece Dunn, Larry Evans,
+Doug Gregor, Joel de Guzman, Baptiste Lepilleur, Andy Little, Paul Mensonides,
+Dan Nuffer, Andreas Pokorny, Vladimir Prus, Gennadiy Rozental, Michiel Salters,
+Jonathan Turkanis, Chris Uzdavinis, Pavel Vozenilek, Michael Walter for bug
+reports, fixes and hints.
+
+- Added support for the MS extensions #region and #endregion, which simply get
+ ignored by Wave. The support for these is enabled only, when the pp constant
+ BOOST_WAVE_SUPPORT_MS_EXTENSIONS is defined. Otherwise these get flagged as
+ an illegal preprocessor directive (as before).
+- Fixed a problem, where the replacement text for a #pragma directive got lost
+ if this directive was on the last line of a processed (include-)file.
+- Changed the default value for BOOST_WAVE_SUPPORT_MS_EXTENSIONS for non-
+ Windows systems to zero.
+- Updated outdated external links in the documentation.
+- Fixed certain grammatical and stylistic quirks in the documentation.
+- Fixed a problem in libs/wave/build/Jamfile.v2 (as reported by Larry Evans).
+ Fixed the Jamfile.v2 in the samples directories accordingly.
+- Added the '<toolset>vc-7_1:<rtti>off' to all Jamfile.v2 files to adjust for
+ the internal buffer overflow bug in the VC7.1 compiler (reported by Joel de
+ Guzman).
+- Changed the '<toolset>vc-7_1:<rtti>off' to '<toolset>vc-7.1:<rtti>off' as
+ required by the Boost.Build.v2 library (suggested by Vladimir Prus).
+- Finally fixed the Jamfile.v2 file (after a suggestion from Reece Dunn)
+- Fixed the column number reported for tokens for Slex lexer based
+ configurations (reported by Baptiste Lepilleur).
+- Added the __BASE_FILE__ predefined macro, which contains a string literal
+ of the main file name to preprocess (the one the context<> template was
+ created with). (suggested by Pavel Vozenilek)
+- Used the boost::reverse_iterator instead of the std::reverse_iterator
+ for the flex_string class to allow compilation of Wave with VC7.0
+ (as suggested by Reece Dunn).
+- Fixed a problem in the include_path template, which throwed a
+ boost::filesystem exception whenever a character was used in a file name
+ to include, which is marked as illegal by the default name checker of the
+ boost::filesystem::path.
+
+Version 1.1.13 (Boost review candidate 2, bug fixed version)
+- Fixed a problem, where the context<> template referenced temporary iterator
+ objects from the underlying stream (thanks to Michiel Salters for reporting
+ this).
+- Fixed a bug in the re2c lexer, which allowed to dereference the end iterator
+ of the underlying input stream (thanks to Doug Gregor for pointing this out).
+- Fixed several assertions fired by the iterator checking code of the VC8 stl.
+
+Version 1.1.12 (Boost review candidate)
+- A rough performance analysis showed, that 30% of the time is spent parsing
+ the input for pp directives (cpp_grammar), 35% of the time is spent inside
+ the flex_string code, mainly in the copy constructor and assignment
+ operator, 15% of the time is spent inside the list and vector member
+ functions, 10% is spent for memory allocation but only 1% of the time is
+ spent in the re2c lexer.
+- Identified a performance problem, where the token_cache was instantiated
+ for every created lexer object, but needed to be initialised only once.
+- Added #include <wave_version.hpp> to wave_config.hpp
+- Fixed problems reported by the gcc 3.4.1 compiler.
+- Adjusted Jamfiles for the new toolset names introduced in Boost V1.32.
+
+Version 1.1.11
+- Updated copyrights.
+- Fixed some bugs introduced by the latest refactoring.
+- Tried to fix the expansion of macros, which replacement-list terminates in a
+ partial macro expansion. No success so far.
+
+Version 1.1.10
+- Refactored some of the macro map (macro namespace) code (added comments,
+ splitted into separate files),
+- Fixed some typename errors in cpp_macromap.hpp (thanks to Vladimir Prus).
+- Fixed the BoostBuild V2 Jamfiles (thanks to Vladimir Prus).
+
+Version 1.1.9
+- Moved all of the #pragma wave option(value) operators out of the wavelib into
+ the wave driver program. Removed enable_trace() and trace_flags() policy
+ functions. Renamed trace_policy into context_policy.
+- Added the defined_macro() and undefined_macro() preprocessing hooks to allow
+ easily to build macro cross referencers and such.
+
+Version 1.1.8
+- Replaced the usage of the string::erase() and string::insert() functions,
+ which were the only non-const string member functions used.
+- Token pasting is now well defined in variadics mode (was in C++0x mode only).
+- Changed the timing code in the wave driver to include the parsing of
+ files included by the --forceinclude command line switch.
+- Performance measurements (very informal) [sec], the files are some of the
+ preprocessor specific test cases from Paul Mensonides chaos_pp library.

+Wed Aug 25 13:23:27 WEDT 2004
+Version 1.1.7
+- Branched for Boost Release.
+- Removed several features from the code base:
+ . removed C++0x support
+ . removed TST support
+- Fixed the program_option validator syntax, which has changed since the last
+ update.
+- Removed misleading configuration options from the cpp_config.hpp file,
+ because the application will have to use the same config options as were used
+ during the compilation of the library.
+- Changed the naming convention of typedef'd types in the library. Removed the
+ _t suffix, wherever possible.
+- Updated the documentation to reflect the removal of the C++0x features.
+
+- Changed the licensing scheme to:
+// Copyright 2004 Joe Coder. Distributed under the Boost
+// Software License, Version 1.0. (See accompanying file
+// LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt)
+
+Mon May 24 10:02:47 WEDT 2004
+Version 1.1.6
+- Fixed a incompatibility with the new program_options version.
+
+Version 1.1.5
+Version 1.0.6
+- Fixed a bug, which reported an #include statement as ill formed, if it was
+ followed by an empty C comment only. This was an error in the cpp.re regular
+ expression for C comments. Additionally, since this change simplified the
+ Re2C generated lexer a lot it was possible to remove the compiler workaround
+ for the VC7.1 compiler which prevented the optimization of this lexer.
+
+Mon Mar 29 09:36:59 WEDT 2004
+- Corrected the signature of the main() functions (was main(int, char const*[])).
+
+Sun Mar 28 12:55:59 WEDT 2004
+Version 1.1.4
+- Fixed a problem, where the first returned token was lost, whenever a
+ --forceinclude file was given.
+- Adjusted the Wave driver and the other samples to use the new program_options
+ library syntax (V1.1.x only).
+
+Mon Mar 1 19:14:21 WEST 2004
+Version 1.1.2
+Version 1.0.4
+- Fixed a problem, which does not report an error, if in a #define statement in
+ between a macro name and its replacement list were no whitespace given.
+- Fixed a bug, which generated an unexpected exception of the $ character in the
+ input.
+- Macro definitions, which differ by whitespace only (one definition contains
+ whitespace at a certain position, the other definition does not) are correctly
+ reported as a warning now.
+- Fixed a problem, where different formal argument names during macro
+ redefinition were not flagged as a warning.
+- A wide character string used in a #line directive wasn't flagged as an error.
+
+Sun Feb 29 19:10:14 WEST 2004
+Used the test suite distributed with the mcpp V2.4 preprocessor to fix a bunch
+of mostly minor issues:
+- Fixed trigraph backslash followed by a newline handling (??/ \n) in the
+ re2c (C/C++ and IDL) scanners.
+- Fixed a digraph/trigraph token type handling problem during macro expansion.
+- Fixed a digraph/trigraph token type problem during handling of the null
+ preprocessor directive.
+- Fixed several signed/unsigned conversion bugs in the expression evaluator.
+- Fixed the || and && operators in the expression evaluator to stop evaluation,
+ as only the outcome of the overall expression is determined.
+- Fixed the expression evaluation engine to detect divide by zero errors.
+- Fixed a bug with operator || and && arithmetic (the deduced type was wrong).
+- Fixed a bug with the unary operators ! and - which IN conjunction with an
+ arithmetic operation yielded A wrong result type.
+- Fixed a bug, which reported a macro definition as an invalid redefinition, if
+ it was different from the original definition only by different whitespaces.
+- Fixed a bug, which reported the redefinition of one of the alternative tokens
+ as 'and', 'bit_and' etc. as invalid.
+- Fixed a bug in the character literal parser, which prevented the recognition
+ of multibyte character literals.
+
+- Moved the cpp_token_ids.hpp header into the main wave.hpp header, because the
+ values defined therein aren't changeable by the user anyway.
+- Fixed some spelling errors in the documentation (thanks to Rob Stewart).
+
+Tue Feb 3 20:20:16 WEST 2004
+- Fixed the problem, that macro definitions in a config file were flagged as
+ an error, if there was any whitespace in between the -D and the macro name
+ (same problem existed for -P).
+
+Fri Jan 30 20:28:27 WEST 2004
+- Fixed a missing boostification in the trace support header.
+- Added a missing std:: namespace qualification to the list_includes.cpp sample
+ file.
+- Fixed line ending problems with the cpp.re and idl.re files.
+- Added quick_start sample.
+
+Sun Jan 25 20:26:45 WEST 2004
+This version was submitted to Boost as the review candidate (V1.1.0)
+- Fixed invalid explicit instantiation syntax as reported by the Comeau
+ compiler.
+- Added a missing header to flex_string.hpp.
+
+Sat Jan 24 19:47:44 WEST 2004
+- Completely decoupled the used lexer from the preprocessor.
+- Unfortunately had to change the template interface of the context class. It
+ now instead of the token type takes the type of the lexer to use.
+- Reintroduced the cpp_tokens, list_includes and waveidl samples.
+ . cpp_tokens is based on the SLex lexer
+ . list_includes shows the usage of the include file tracing capability
+ . waveidl uses the Re2C based IDL lexer in conjunction with the default token
+ type
+
+Tue Jan 13 20:43:04 WEST 2004
+- Fixed several compilation issues under linux (gcc 3.2.3, gcc 3.3, gcc 3.3.2,
+ gcc 3.4, Intel V7.1)
+- Fixed a compatibility problem with Spirit versions older than V1.7.
+
+Mon Jan 12 20:39:50 WEST 2004
+- Boostified the code base:
+ . Moved code into namespace boost.
+ . Prefixed all pp constants with "BOOST_".
+ . Refactured the directory structure.
+- Removed IDL mode and SLex lexer from the code base. These will be re-added as
+ samples.
+- Changed the Wave configuration system to be more flexible (all
+ #if defined(BOOST_WAVE_...) changed to #if BOOST_WAVE_... != 0),
+ which allows to configure the library without changing the code base itself
+
+Sat Jan 10 18:17:50 WEST 2004
+- Incorporated Andrei Alexandrescu's latest changes to the flex_string class,
+ which resulted in an overall spedd gain of about 5-10%.
+
+Wed Jan 7 17:46:45 WEST 2004
+- Found a major performance hole! The achieved general speedup is about 50-70%.
+- Added missing old MS specific extensions to the re2c lexer (_based,
+ _declspec, _cdecl, _fastcall, _stdcall, _inline and _asm).
+- Added support for #include_next (as implemented by gcc).
+- Fixed compilation problems with gcc 3.3.1
+- Avoid to look up in symbol table of a potential macro name twice.
+- Added the Spirit SLex lexer sample to the Wave source tree, because it was
+ removed from the Spirit distribution.
+- Removed the configuration option, which allowed to reverse the names stored
+ in the symbol tables.
+- Implemented experimental support for using a TST (ternary search tree) as the
+ container for the symbol tables.
+
+Sun Jan 5 12:30:50 2004
+- Released V1.0.0
+
+Sun Jan 4 00:11:50 2004
+- Removed tabs from the flex_string.hpp file.
+- Modified the input_functor.hpp file to sqeeze out some milliseconds at
+ runtime.
+- The --timer option now prints the overall elapsed time even if an error
+ occurred.
+- Added support for #pragma once.
+
+Fri Jan 2 22:58:54 2004
+- Fixed a bug in the code, which predefines the preprocessor constants.
+- Fixed a bug in intlit_grammar<> initialisation code.
+
+Thu Jan 1 21:15:03 2004
+- Fixed a bug while predefining a macro with a value through the commmand line.
+- Fixed a bug, which reported a macro definition as illegal, if the redefined
+ macro was a function like macro with parameters.
+- Fixed a bug, if concatenation of two tokens resulted in a C++ comment start
+ token.
+
+Thu Jan 1 15:01:54 2004
+- Finished license migration.
+
+Wed Dec 31 12:23:55 2003
+- Changed the copyright and licensing policiy to be Boost compatible.
+
+Wed Dec 31 12:01:14 2003
+- Fixed a problem while compiling certain headers from the Microsoft Windows
+ SDK:
+ #define CreateWindowA(lpClassName, lpWindowName, dwStyle, x, y,\
+ nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)\
+ CreateWindowExA(0L, lpClassName, lpWindowName, dwStyle, x, y,\
+ nWidth, nHeight, hWndParent, hMenu, hInstance, lpParam)
+ where essentially is no whitespace between the parameter list and the macro
+ replacement list.
+- Fixed a problem with the MS extension __declspec, which now is recognized
+ correctly.
+
+Sat Dec 27 14:48:29 2003
+- Fixed remaining problems with assign/assign_a.
+- Fixed some gcc warnings about signed/unsigned comparision mismatch.
+
+Tue Nov 11 20:51:41 WEST 2003
+- Changed the IDL mode to recognize identifiers only. All keywords (except
+ 'true' and 'false') are returned as identifiers. This allows for easy
+ extension of the IDL language. The drawback is, that after preprocessing
+ there needs to be just another lexing stage, which recognizes the keywords.
+- Fixed a possible problem, when in between a #if/#elif directive and a
+ subsequent opening parenthesis Wave finds no whitespace:
+ #if(_WIN_VER >= 0x0500)
+ is now recognized correctly.
+ (This problem was pointed out by Porter Schermerhorn).
+
+Sun Nov 9 21:05:23 WEST 2003
+- Started to work on implementation of an IDL lexer for the TAO idl compiler.
+ . Branched off the Re2C C++ lexer and related files as a starting point for
+ the new IDL lexer. Added connfiguration means to allow compile time
+ decision, in which mode to operatoe (C++ or IDL).
+ . Implemented the Re2C based IDL lexing component.
+ . Fixed all occurrences of non-IDL tokens (as T_COLON_COLON and T_ELLIPSIS)
+
+Sat Nov 8 20:05:52 WEST 2003
+- Version 1.0.0
+- Munged the email addresses embedded within the source files.
+- Adjusted for the new actor names in Spirit (assign_a and append_a).
+
+Thu Aug 21 16:54:20 2003
+- Removed the internally used macro 'countof()' to avoid possible nameclashes
+ with user code.
+- Fixed a bug, which prevented the execution of the concatination operator '##'
+ while expanding object-like macros.
+
+Tue Aug 5 10:04:00 2003
+- Fixed a false assertion, if a #pragma directive started with some whitespace
+ on the line.
+- Added the #pragma wave timer() directive to allow rough timings during
+ processing. This is done on top of a new callback hook for unrecognized
+ #pragma's, which allows to easily add new pragma commands without changing
+ the Wave library.
+- Fixed a bug in the whitespace insertion engine, which prevented the insertion
+ of a whitespace token in between two consecutive identifier tokens or a
+ integer literal token followed by an identifier token.
+- Fixed a bug during macro concatenation, which allowed to concatenate
+ unrelated tokens from the input stream:
+ #define CAT(a, b) PRIMITIVE_CAT(a, b)
+ #define PRIMITIVE_CAT(a, b) a ## b
+ #define X() B
+ #define ABC 1
+ CAT(A, X() C) // AB C
+ CAT(A, X()C) // correct: AB C, was 1
+- Fixed a 64 bit portability problem.
+- Added pragma wave timer(suspend) and wave timer(resume)
+- Fixed a ODR problem with static initialization data for predefined macros.
+- Ported the iterators to the new iterator_adaptors.
+- Updated the documentation to reflect the recent changes
+
+Sun Jun 29 12:35:00 2003
+- Fixed 64 bit compatibility warnings.
+- Fixed a bug, which prevented the correct recognition of a #line directive, if
+ only the filename part of this directive was generated by a macro expansion.
+- Fixed a bug during macro expansion of conditional expressions, which
+ prevented the correct expansion of certain scoped macros.
+
+Fri Jun 27 09:50:14 2003
+- Changed the output of the overall elapsed time (option --timer) to cerr.
+- Added a configuration constant WAVE_REVERSE_MACRONAMES_FOR_SYMBOLTABLE, which
+ reverses the macro names while storing them into the symbol table, which
+ allows to speed up name lookup especially, if the macro names are very long
+ and if these share a common prefix.
+- Fixed a very subtle bug, which prevented the recognition of fully qualified
+ macro names during the macro expansion of conditionals expressions (for
+ #if/#elif).
+- Improved the error output for the illformed pp expression error.
+
+Thu Jun 26 08:20:30 2003
+- Done a complete spell check of the source code comments.
+
+Wed Jun 25 20:33:52 2003
+- Changed the conditional expression engine to work with integer numeric
+ literals only. Distinguished signed and unsigned literals.
+- Importing a region twice is allowed now.
+- Fixed a bug, which does not removed all placeholder tokens from a expanded
+ token sequence while evaluating conditional expressions (C++0x mode only).
+
+Wed Jun 25 15:01:51 2003
+- Changed the conditional expression engine to respect the type of numeric
+ literals, now expressions like '#if 1 / 10 == 0' evaluate correctly (to true
+ :-)
+- Fixed a bug, where macro names referring to global macros (as ::A::B) were
+ not correctly recognized under certain circumstances.
+- Empty parameter lists for macros with ellipses only sometimes generated a
+ placemarker token in the output:
+ #define STR(...) #__VA_ARGS__
+ STR() // resulted in "§" instead of "" .
+
+Wed Jun 25 08:35:06 2003
+- Fixed several gcc compilation errors (missing typename's etc.)
+- Fixed a compilation problem, if Wave is built on top of the SLEX scanner.
+- Reformatted the --timer output from pure seconds to a more reasonable format.
+
+Fri Jun 20 19:33:30 2003
+- Changed the enable_tracing function of the tracing_policies to take a
+ trace_flags variable instead of a bool, to allow to control tracing with more
+ granulation.
+- Added the tracing_enabled function to the tracing_policies, which returns the
+ current tracing status.
+- Updated the documentation of the tracing policies.
+
+Thu Jun 19 21:45:39 2003
+- Reactivated the list_includes sample with the help of the new include file
+ tracing facility.
+
+Thu Jun 19 17:55:35 2003
+- Eliminated the TraceT template parameter from the macromap<> template.
+- Added two hooks to the trace policy to allow to trace the opening and
+ closing of include files.
+
+Thu Jun 19 14:08:10 2003
+- Added the command line option --timer, which enables the output to std::cout
+ of the overall elapsed time during the preprocessing of the given file.
+
+Fri Jun 13 09:11:29 2003
+- Emitted an error message, if an ellipses was found as a formal macro
+ parameter and variadics were disabled.
+- Fixed a false error message, that the last line was not terminated with a
+ newline, which occurred, if no output was generated by the last line of the
+ source file.
+
+Thu Jun 12 15:20:22 2003
+- Fixed the recent change in argument expansion for the variadics/C99/C++0x
+ mode.
+- Fixed a problem, where an additional whitespace between _Pragma and the
+ opening parenthesis resulted in a false error message.
+- Used a pool allocator for the token sequence containers (std::list<>'s),
+ which gives a speed gain of more than 60% (while profiling the Order
+ library).
+
+Wed Jun 11 22:18:54 2003
+- Fixed a macro scoping/expansion problem, when a macro returned a full scope
+ which is continued on the call site to form a full qualified name, the name
+ wasn't recognized correctly:
+ # region A
+ # define MACRO 1
+ # region B
+ # define MACRO 2
+ # endregion
+ # endregion
+ # define ID(x) x
+ ID(A)::MACRO // 1
+ ID(A::B)::MACRO // 2, was expanded to A::B::MACRO
+- Changed the expansion of macro arguments such, that these will be expanded
+ only, if the result is to be used for substitution during the expansion
+ of the replacement list.
+
+Wed Jun 11 14:40:29 2003
+- Included a whitespace eating finite state machine (FSM) for minimal
+ whitespace in the generated output. This was suggested by Paul Mensonides.
+- Updated the acknowledgement section
+
+Wed Jun 4 08:03:04 2003
+- Fixed a bug reported by Faisal Vali, which prevented the correct evaluation
+ of conditional expressions, if these referenced macro names, which expanded
+ to a sequence containing non-expandable tokens.
+- Fixed the above bug for #elif directives too (in the first place this was
+ fixed for #if directives only)
+
+Mon May 26 22:15:40 2003
+- Added missing copyrights in several files.
+- Fixed false output, if a unknown _Pragma were encountered.
+- Fixed a macro expansion problem with qualified names, were constructs like
+ the following were not expanded correctly:
+ #define ID(x) x
+ #region SCOPE
+ # define TEST 1
+ #endregion
+ ID(SCOPE::) TEST // should expand to 1
+- Changed #import semantics for macros from copy semantics to reference
+ semantics, i.e. macros are now considered to be implicitly imported into the
+ scope, where they are defined. If a macro is imported into another scope and
+ the original macro is undefined, the imported macro still exists. Further,
+ if the imported macro is expanded, then while rescanning the original macro
+ is disabled too:
+ #region A
+ # define B(x) x
+ #endregion
+ #import A
+ B (A::B) (*) // A::B(*)
+ A::B (B) (*) // B(*)
+ B (B) (*) // B(*)
+ A::B (A::B) (*) // A::B(*)
+- Fixed a recently introduced problem, where placemarker tokens slipped through
+ to the output under certain conditions (in variadics/C99/C++0x modes only).
+
+Mon May 19 16:30:49 2003
+- Fixed a bug, which prevented the recognition of the __lparen__, __rparen__ or
+ __comma__ alternative tokens, if these were the first token after an emitted
+ #line directive (reported by Vesa Karvonen).
+- Added an optimization, that only those tokens are considered for a macro
+ expansion, which may result in an expansion.
+
+Tue May 13 18:16:26 2003
+- Fixed a newly introduced problem, where a omitted argument consisting out
+ of whitespace only were failed to be replaced by a placemarker token. This
+ lead to problems with constructs like the following:
+ #define paste(a, b, c) a ## b ## c
+ paste(1, , 3) // should expand to 13, but expanded to 1## 3
+- Fixed a problem with the tracing support, which throwed an unexpected
+ exception if there were too few arguments given while expanding a macro.
+- Allowed to open and to import the global scope ('#region ::' and
+ '#import ::').
+- Fixed a bug, if more than one file was given with a --forceinclude command
+ line option.
+
+Sat May 10 21:30:29 2003
+- Added __STDC_FULL_REGION__ and __STDC_CURRENT_REGION__ to the list of not
+ undefinable macros.
+- In normal C++ mode and C99 mode the #ifdef/#ifndef and the operator defined()
+ should not support qualified names. This is fixed now.
+- Updated the documentation.
+- Fixed minor gcc -Wall compilation warnings.
+- Added better error support for qualified names used as arguments for #ifdef,
+ #ifndef and operator defined().
+
+Sat May 10 09:51:18 2003
+- Removed the feature, that the comma before the ellipsis parameter in a macro
+ definition may be omitted.
+- Resolved an issue with the expansion of qualified macros, when these
+ qualified names were partially generated by a previous macro expansion
+- Allowed to specify fully qualified names as arguments to the #region directive
+
+Wed May 7 22:44:21 2003
+- Changed the names of __SCOPE__ and __FULL_SCOPE__ predefined macros to
+ __STDC_CURRENT_REGION__ and __STDC_FULL_REGION__ resp. The names are subject
+ to change if the #region keyword actually will be renamed to #scope/#module
+ or whatever.
+- In C++0x mode it is now possible to omit the last comma before a variadics
+ ellipsis in a macro definition:
+ #define cat_i(a, b, c, d, e ...) a ## b ## c ## d ## e
+- Fixed a bug in the stringize code, where an ellipsis to stringize resulted in
+ stringizing of the first ellipsis parameter only. Preserved the original
+ whitespace delimiting in between the ellipsis arguments.
+- Introduced the wave::language_support enum for convenient switching of the
+ supported language features throughout the library.
+- Fixed a bug, which prevented the definition of the predefined macro
+ __WAVE_HAS_VARRIADICS__, if --variadics were given on the command line.
+
+Tue May 6 15:49:45 2003
+- Made predefined macros available at every macro scope without qualification.
+- Predefined a new macro in C++0x mode: __STDC_GLOBAL__, which is defined at
+ global macro scope only and equals to '1' (integer literal).
+- In C++0x mode there are two new predefined macros:
+ __SCOPE__: expands to the last part of the qualified name of the
+ current macro scope
+ __FULL_SCOPE__: expands to the full qualified name of the current macro
+ scope
+
+Mon May 5 23:02:48 2003
+- Fixed a problem in the new well defined token pasting code, which occurred for
+ constructs like the following:
+ #define is_empty(...) is_empty_ ## __VA_ARGS__ ## _other
+ i.e. where two or more '##' operators were contained in the replacement text.
+- Implemented __comma__, __lparen__ and __rparen__ alternative pp-tokens, which
+ may be used as the ',', '(' and ')' tokens during preprocessing. These are
+ only converted to there respective string representation in a special
+ translation phase after preprocessing. This was proposed by Vesa Karvonen.
+- Changed the macro scoping rules to: "If a qualified name does not find a
+ nested name, it is not a qualified name to the preprocessor." This seems to
+ be the simplest usable solution for the possible ambiguities.
+- Fixed a bug in the macro expansion engine in C++0x mode, where the skipping
+ of whitespace inside of a qualified name wasn't consistent.
+
+Sun May 4 10:48:53 2003
+- Fixed a bug in the expression grammar, which prevented 'not' to be recognized
+ as a valid operator.
+- Qualified names are now supported as parameters to #ifdef and #ifndef too.
+- Remove one specialization of the macro expansion engine. It gets instantiated
+ only twice now (for the main input iterator and for list<>'s of tokens.
+- Simplified the required explicit specialization of the defined_grammar
+ template. It has to be explicitely instantiated by providing the token type
+ only (just as for the explicit instantiations of the other grammars).
+
+Fri May 2 22:44:27 2003
+- Qualified names are now allowed as parameters to the operator defined() in
+ C++0x mode.
+- Separated the defined() functionality into a separate translation unit to
+ work around a VC7.1 ICE.
+
+Fri May 2 15:38:26 2003
+- The C++0x mode now has a special set of predefined macros.
+- The predefined macro __WAVE_HAS_VARIADICS__ is now defined in C99 and C++0x
+ modes too (--variadics is implied for these modes).
+- Updated the documentation to reflect the recent changes and additions.
+- In C++0x mode Wave now supports macro scopes:
+ - new keywords #region/#endregion/#import
+ - qualified macro names
+- In C++0x mode Wave now supports token pasting of unrelated tokens. These are
+ concatenated, the result is re-tokenized and inserted into the output stream.
+- Fixed a minor bug in the macro expansion engine, if a qualified function-like
+ macro was found in an object-like context.
+- Fixed an issue with well defined token pasting of unrelated tokens.
+
+Tue Apr 29 08:47:37 2003
+- Fixed a bug in the macro expansion engine, which prevented the expansion
+ of a certain macro under specific conditions (if the left of two tokens to
+ concatenate were a disabled one (T_NONREPLACABLE_IDENTIFIER), then the
+ resulting token was disabled too).
+- Added additional diagnostics to the Wave driver to disambiguate the C99 and
+ C++0x modes.
+- Implemented a new API function and a corresponding Wave driver command line
+ option, which allows to specify one or more include files to be preprocessed
+ before the regular file is preprocessed (the files are processed as normal
+ input and all the resulting output is included, before processing the regular
+ input file). The Wave driver command line option is --forceinclude (-F).
+- Wave now compiles the Order library from Vesa Karvonen.
+
+Mon Apr 28 07:57:10 2003
+- Fixed a bug in the macro expansion engine.
+- Removed a lot of (not needed) whitespace in the generated output (but still
+ not optimal).
+
+Sat Apr 26 20:30:53 2003
+- Fixed a bug in the initialization code of the Slex lexer while working in
+ C99 mode (reported by Reece Dunn).
+
+Fri Apr 18 08:37:35 2003
+- Fixed the handling of option_value's inside of pragma directives:
+ _Pragma("wave option(option_value)")
+ inside which all all whitespaces were deleted.
+- Started to implement experimental macro scoping.
+
+Thu Apr 10 10:20:07 2003
+- Fixed a problem with the #pragma wave stop(), where only the first token
+ inside the stop directive was output, when the preprocessor stops in result
+ of this pragma.
+- Implemented a new #pragma wave system(command), which spawns a new operation
+ system command exactly as specified inside the system directive, intercepts
+ the stdout output of this process, retokenizes this output and inserts the
+ generated token sequence in place of the original #pragma or operator _Pragma.
+ Please note that the generated output is _not_ subject to any macro expansion
+ before its insertion as the replacement of the pragma itself. If you need to
+ macro expand the replacement text, you always may force this by writing:
+ #define SCAN(x) x
+ SCAN(_Pragma("wave system(...)"))
+ which re-scans the replacement once.
+- Replaced the Wave position_iterator with the boost::spirit::position_iterator
+ (without any problems!).
+
+Mon Apr 7 10:45:30 2003
+- Fixed macro_trace_policies::expand_object_like_macro not to be called with
+ the formal arguments as one of its parameters.
+- Updated the documentation to reflect the changes needed for the tracing
+ stuff.
+
+Mon Mar 31 19:07:05 2003
+- Fixed variadics support in the trace output.
+- Fixed preprocessing of operator _Pragma() before it's execution.
+- Added _Pragma("wave stop(errmsg)") (#pragma wave stop(errmsg)) to allow
+ diagnostics output from inside macro expansion.
+- Fixed operator _Pragma for unknown pragmas (these are simply put through to
+ the output).
+- Implemented a maximal possible include nesting depth to avoid an out of
+ memory error. The initial value for this is configurable through the compile
+ time constant WAVE_MAX_INCLUDE_LEVEL_DEPTH, which defaults to 1024, if not
+ given.
+ Additionally this may be enlarged through a new command line option:
+ -n/--nesting (Wave driver only).
+
+Sun Mar 30 20:40:17 2003
+- Implemented the predefined macro __INCLUDE_LEVEL__, which expands to a
+ decimal integer constant that represents the depth of nesting in include
+ files. The value of this macro is incremented on every '#include' directive
+ and decremented at every end of file.
+- Implemented the operator _Pragma(). It is recognized in C99 mode and whenever
+ variadics are enabled.
+
+Sun Mar 30 08:30:12 2003
+- Changed the tracing format to be more readable.
+- Changed the tracing #pragma's to
+ enable tracing: #pragma wave trace(enable)
+ disable tracing: #pragma wave trace(disable)
+ or
+ enable tracing: #pragma wave trace(1)
+ disable tracing: #pragma wave trace(0)
+- Changed the semantics of the -t (--traceto) switch. Without any -t switch
+ there isn't generated any trace output at all, even, if the corresponding
+ #pragma directives are found. To output the trace info to a file, the
+ '-t file' syntax may be used, to output to std::cerr, the '-t-' (or '-t -')
+ syntax may be used.
+
+Fri Mar 28 17:27:25 2003
+- Added a new template parameter to the wave::context<> object, which allows
+ to specify a policy for controlling the macro expansion tracing. The default
+ macro_trace_policy does no tracing at all. This way one can add specific
+ macro expansion tracing facilities to the library.
+- #pragma directives starting with a STDC identifier are no longer not macro
+ expanded in C++ mode, in C++ mode these are now expanded as usual, in C99
+ mode not.
+- The tracing can be enabled/disabled from inside the preprocessed stream by
+ inserting a special #pragma directive:
+ enable tracing: #pragma wave_option(trace: enable)
+ disable tracing: #pragma wave_option(trace: disable)
+- The Wave driver now allows to specify a destination for the macro expansion
+ tracing trough a new command line switch: '-t path' or '--traceto path'. If
+ this option isn't given, the trace output goes to stderr.
+- The Wave driver now allows to specify the name of the file, where the
+ preprocessed result stream is to be saved: '-o path' or '--output path'. If
+ this option is not given, the output goes to stdout.
+
+Wed Mar 26 20:39:11 2003
+- Fixed a problem with alternative tokens (as 'and', 'or' etc.) and trigraph
+ tokens, which were not correctly recognized inside #if/#elif expressions.
+- Alternative tokens ('and', 'or' etc.) are no longer subject to a possible
+ macro redefinition.
+- Fixed the special handling of 'true' and 'false' during the macro expansion
+ of #if/#elif expressions.
+
+Tue Mar 25 12:12:35 2003
+- Released Wave V0.9.1
+
+Mon Mar 24 13:34:27 2003
+- Implemented placemarkers, i.e. Wave now supports empty arguments during macro
+ invocations. This must be enabled by means of a new pp constant:
+ WAVE_SUPPORT_VARIADICS_PLACEMARKERS which must be defined to enable the
+ placemarker and variadics code and by defining the command line option
+ '--variadics' (Wave driver only).
+- Implemented variadics, i.e. Wave now supports macros with variable parameter
+ counts. This must be enabled by means of the pp constant:
+ WAVE_SUPPORT_VARIADICS_PLACEMARKERS which must be defined to enable the
+ placemarker and variadics code and by defining the command line option
+ '--variadics' (Wave driver only).
+- Implemented a C99 mode. This mode enables variadics and placemarkers by
+ default and rejects some specific C++ tokens (as the alternate keywords and
+ '::', '->*', '.*'). This mode must be enabled by the means of the pp constant
+ WAVE_SUPPORT_VARIADICS_PLACEMARKERS (see above). The C99 mode is enabled by
+ the command line switch '--c99' (Wave driver only).
+ This involved some changes in the C99/C++ lexers.
+
+Fri Mar 21 16:02:10 2003
+- Fixed a bug in the macro expansion engine, which prevented the expansion of
+ macros, which name was concatenated out of a identifier and a integer
+ followed directly by another identifier:
+ #define X() X_ ## 0R() // note: _zero_ followed by 'R'
+ #define X_0R() ...
+ X() // expanded to: X_0R(), but should expand to ...
+ This is a problem resulting from the fact, that the Standard requires the
+ preprocessor to act on so called pp-tokens, but Wave acts on C++ tokens.
+
+Thu Mar 20 21:39:21 2003
+- Fixed a problem with expression parsing (#if/#elif constant expressions),
+ which failed to produce an error message for expressions like
+ #if 1 2 3 4 5
+ i.e. where the token sequence starts with a valid constant expression, but
+ the remainder of the line contained other tokens than whitespace.
+- Integrated the flex_string class from Andrei Alexandrescu (published on the
+ CUJ site) to get COW-string behaviour for the token values and position
+ filename strings. This resulted in a major overall speedup (about 2-3 times
+ faster in dependency of the complexity of pp usage in the input stream).
+- Fixed a bug, which reported ill formed #if/#else expressions as errors, even
+ if the current if block status (conditional compilation status) is false.
+- Added a warning, if the last line of a file does not end with a newline.
+- Improved error recognition and handling for malformed preprocessor directives
+
+Mon Mar 17 19:53:29 2003
+- Fixed a concatenation problem: constructs like a##b##c where expanded
+ incorrectly.
+- Optimized the recognition of pp directives:
+ - the parser is used only, if the next non-whitespace token starts a pp
+ directive
+ - null directives now are recognized without calling the parser
+ - the parser isn't called anymore, if the if_block_status is false and no
+ conditional pp directive (#if etc.) is to be recognized.
+ These optimizations give a speed improvement by upto 40%.
+- Removed adjacent whitespace during macro expansion (needs to be revised,
+ since there is some whitespace left, which may be removed)
+
+Sun Mar 16 23:19:11 2003
+- Fixed a problem with include paths given on the command line, if the file
+ to preprocess was not given as a full path (driver executable).
+- Fixed a problem with path names containing blanks (driver executable).
+- Cleaned command line and argument handling (driver executable).
+- Fixed a severe memory leak.
+- Fixed a bug, if a C++ keyword was used as a macro name or macro parameter
+ name, which prevented the macro recognition and expansion to function
+ properly.
+- Implemented the WAVE_SUPPORT_MS_EXTENSIONS compiler switch for the re2c
+ generated lexer too.
+- Fixed a problem, which caused an internal T_PLACEHOLDER token to show up
+ outside the macro replacement engine.
+- Fixed a problem with macro #include directives, which prevents to find the
+ file to include, if after the macro expansion the token sequence representing
+ the filename began or ended with at least one whitespace token.
+- Fixed a problem, which caused a false error message if the '#' character was
+ to be concatenated with an arbitrary other token.
+- The concatenation of a whitespace token with an arbitrary other token was
+ reported as illegal token pasting (but it is certainly not).
+
+Sat Mar 15 21:43:56 2003
+- Added a default constructor to the wave::util::file_position template.
+- Report the concatenation of unrelated tokens as an error.
+- Finished the documentation.
+
+Fri Mar 14 20:14:18 2003
+- More work on documentation
+- Changed file_position to expose accessor functions (the member variables are
+ marked as private now). This opens up the possibility to provide another
+ file_position implementation, which may be optimized in some way.
+- Fixed a problem with the token name table, the alternate and trigraph token
+ names were printed incorrectly.
+- Fixed a bug, which prevented the correct recognition of 'defined X' (without
+ parenthesises).
+- Fixed a bug, which allowed to redefine and undefine the predefined name
+ 'defined'.
+- Fixed a bug, which prevents the correct recognition of a macro based #include
+ directive, if it expands to something like #include <...>.
+- Fixed a bug, which prevented the recognition of duplicate macro parameter
+ names.
+- Removed the insertion of additional whitespace inside of string literals
+ (during stringizing).
+
+Wed Mar 12 19:16:40 2003
+- Fixed a bug, which prevented the instantiation of the wave::context object
+ with auxiliary iterators. The token type isn't coupled anymore with the
+ iterator type.
+ This required some changes in the interface:
+ - The wave::context object now has three template parameters (the iterator
+ type, the token type and the input policy type)
+ - The token type does not have the iterator type as it's template parameter
+ anymore.
+- Implemented a new position_iterator template on top of the iterator_adaptor<>
+ template to make it work even for input_iterator type iterators.
+- Fixed a bug in the regular expressions for the Slex lexer.
+- The function 'set_sys_include_delimiter()' was renamed to
+ 'set_sysinclude_delimiter()' to better fit the naming scheme of the other
+ functions.
+- Wrote more documentation
+- Unified the different token definitions of the lexers, so that there is only
+ one token type left. This required some changes in the interface:
+ - There is no need anymore to explicitly specify the namespace of the token
+ type to use.
+- Added the command line option -P to the Wave driver program, which predefines
+ a macro (i.e. defines it such, that is _not_ undefinable through an #undef
+ directive from inside the preprocessed program).
+
+Sat Mar 8 07:46:43 2003
+- Released Wave 0.9.0
+
+Thu Mar 6 20:02:44 2003
+- Compiled Wave with IntelV7.0/DinkumwareSTL (from VC6sp5)
+- Fixed new compilation problems with gcc -Wall
+- Fixed the list_includes and cpp_tokens samples to compile and link correctly.
+- Fixed a bug, where a wrong filename was reported by the generated #line
+ directive.
+- Fixed a bug, where the __FILE__ macro was expanded without '\"' around the
+ filename.
+- The generated #line directives and the expanded __FILE__ macro now report
+ the filename in a native (to the system) format. Additionally the generated
+ string literals are now escaped correctly.
+
+Wed Mar 5 21:11:14 2003
+- Reorganized the directory structure to mirror the namespace structure of the
+ library
+- Fixed a bug, where the complete input after the first found #include
+ directive were eaten up.
+- Fixed a bug, where the __LINE__ macro expanded to a incorrect linenumber, if
+ the __LINE__ macro was encountered on a line after a '\\' '\n' sequence.
+
+Tue Mar 4 11:50:24 2003
+- The new name of the project is 'Wave'.
+- Adjusted namespaces, comments etc. to reflect the new name.
+- Added the command line option -U [--undefine], which allows to remove one of
+ the predefined macros (except __LINE__, __FILE__, __DATE__, __TIME__,
+ __STDC__ and __cplusplus)
+
+Sun Mar 2 20:10:04 2003
+- Fixed a bug while expanding macros without any definition part (empty macros)
+- The pp-iterator will not emit a newline for every recognized preprocessing
+ directive anymore. The generated output is much more condensed this way.
+- The pp-iterator now emits #line directives at appropriate places.
+- Added an additional parser to the library, which may be used to parse macros
+ given in the command line syntax, i.e. something like 'MACRO(x)=definition'.
+- Added the possibility to the cpp driver sample, to add macros from the
+ command line through the -D command line switch.
+- Martin Wille contributed a test script to allow automatic testing of the
+ cpp driver sample by feeding all files contained in the test_files directory
+ through the cpp driver and comparing the generated output with the
+ corresponding expectations.
+- Added config file support to allow for predefined option sets (for instance
+ for the emulation of other compilers)
+- Changed the way, how include paths are defined. It resembles now the
+ behaviour of gcc.
+ Any directories specified with '-I' options before an eventually given '-I-'
+ option are searched only for the case of '#include "file"', they are not
+ searched for '#include <file>' directives. If additional directories are
+ specified with '-I' options after a '-I-' option was given, these directories
+ are searched for all '#include' directives. In addition, the '-I-' option
+ inhibits the use of the current directory as the first search directory for
+ '#include "file"'. Therefore, the current directory is searched only if it is
+ requested explicitly with '-I.'. Specifying both '-I-' and '-I.' allows to
+ control precisely which directories are searched before the current one
+ and which are searched after.
+- Added config file support to the cpp driver.
+- stored not only the current 'name' of a file (given eventually by a #line
+ directive) but in parallel the actual full file system name of this file too.
+
+Tue Feb 25 21:44:19 2003
+- Fixed the warnings emitted by gcc -Wall.
+- Fixed a bug in the cpp grammar, which causes to failing the recognition of
+ certain preprocessor directives if at the end of this directive were placed
+ a C++ comment.
+- Simplified and extended the insertion of whitespace tokens at places, where
+ otherwise two adjacent tokens would form a new different token, if
+ retokenized.
+
+Mon Feb 24 19:13:46 2003
+- defined() functionality was broken
+- added missing typename keywords
+- added missing using namespace statements, where appropriate
+- added a warning, when a predefined macro is to be undefined (by an #undef
+ directive)
+- removed the 'compile in C mode' hack for the re2c generated lexer (VC7.1
+ (final beta) is not able to compile it with optimizations switched on
+ anyway :( )
+- compiled with gcc 3.2 and Intel V7.0 (20030129Z)
+
+Sun Feb 23 23:39:33 2003
+- Fixed a couple of 'missing typename' bugs (thanks to Martin Wille)
+- Added code to insert whitespace at places, where otherwise two adjacent
+ tokens would form a new different token, if retokenized.
+- Fixed a severe macro expansion bug.
+- Added the handling of invalid or not allowed universal character values
+ inside of string literals and character literals.
+
+Sat Feb 22 20:52:06 2003
+- Bumped version to 0.9.0
+- Added test for invalid or not allowed universal character values (see
+ C++ Standard 2.2.2 [lex.charset] and Annex E)
+- Fixed a bug with newlines between a macro name and the opening parenthesis
+ during the macro expansion and a bug with newlines inside the parameter list
+ during the macro expansion.
+- Added the following predefined macros:
+ __SPIRIT_PP__
+ expands to the version number of the pp-iterator lib (i.e. 0x0090 for
+ V0.9.0)
+ __SPIRIT_PP_VERSION__
+ expands to the full version number of the pp-iterator lib (i.e.
+ 0x00900436 for V0.9.0.436)
+ __SPIRIT_PP_VERSION_STR__
+ expands to the full version string of the pp-iterator lib (i.e.
+ "0.9.0.436")
+
+Fri Feb 21 22:09:04 2003 (feature complete!)
+- Allowed to optionally compile the Re2c generated lexer in 'C' mode, because
+ at least the VC7.1 (final beta) compiler has problems to compile it in 'C++'
+ mode with optimizations switch on
+- Implemented #error and #warning (optional) directives (C++ standard 16.5).
+ Additionally there are now allowed the following preprocessor configuration
+ constants:
+ CPP_PREPROCESS_ERROR_MESSAGE_BODY
+ if defined, preprocesses the message body of #error and #warning
+ directives to allow for better diagnostics.
+ CPP_SUPPORT_WARNING_DIRECTIVE
+ if defined, then the #warning directive will be recognized such, that
+ a warning with the given message will be issued
+- Adjusted the error handling for the Re2c generated C++ lexer, so that any
+ error inside the lexer is now propagated as an cpplexer_exception.
+- Implemented the #line directive (C++ standard 16.4)
+- Implemented #pragma directive (C++ standard 16.6)
+ Additionally there are now allowed the following preprocessor configuration
+ constants:
+ CPP_RETURN_PRAGMA_DIRECTIVES
+ if defined, then the whole pragma directive is returned as a token
+ sequence to the caller, if not defined the whole pragma directive is
+ skipped
+ CPP_PREPROCESS_PRAGMA_BODY
+ if defined, then the #pragma body will be preprocessed
+- Implemented #include directive with macro arguments (C++ standard 16.2.4)
+- Made the namespace structure finer granulated to leave only the main
+ interface classes in the main namespace cpp. All other classes are moved into
+ sub-namespaces to reflect the logical dependencies
+- Reorganized the public interface of the context<> template class, made all
+ non relevant functions into the protected.
+- Implemented predefined macros (__LINE__ et.al.) (C++ standard 16.8)
+- Further documentation work
+
+Wed Feb 19 23:44:47 2003
+- Corrected a lot of bugs in the macro expansion engine, which now should be
+ conformant to the C++ standard.
+- # (null) directive (C++ standard 16.7)
+
+Sun Feb 16 08:40:38 2003
+- Added a macro expansion engine which expands macros with arguments
+ C++ standard 16.3 [cpp.replace]
+- Added a new sample: cpp_tokens. This sample preprocesses a given file and
+ prints out the string representations of all tokens returned from the pp
+ iterator
+- Added documentation (to be continued!)
+- Added a couple of small test files to test elementary functionality
+ (the tests mainly were contributed by Paul Mensonides)
+- The main cpp sample is now a simple preprocessor driver program, which
+ outputs the string representation of the preprocessed input stream. Use
+ cpp --help to get a hint, how to use it.
+- Fixed a bug in the preprocessor grammar which failed to recognize a pp
+ statement, if there was a C++ comment at the end of the line
+- Added '#' operator (C++ standard 16.3.2) [cpp.stringize]
+- Fixed a bug in the slex based C++ lexer to handle the concatenation
+ characters correctly ('\\' followed by a '\n')
+
+Sun Feb 9 23:01:00 2003
+- Improved error handling for #if et.al.
+- Fixed a pair of lexer errors
+- Implemented the #if/#elif statements, the sample now contains a complete C++
+ expression evaluation engine (for the calculation of the outcome of the
+ #if/#elif statement conditions)
+- Implemented macro replacement (with parameters)
+- Implemented the '##' [cpp.concat] operator
+- Implemented the defined() [cpp.cond] operator
+
+Sun Feb 2 23:28:24 2003
+- Implemented the #define, #undef, #ifdef, #ifndef, #else and #endif
+ statements
+- Added optional parse tree output as xml stream (controlled through the config
+ pp constant CPP_DUMP_PARSE_TREE)
+
+Fri Jan 31 21:30:55 2003
+- Fixed different minor issues and a border case (#include statement at the
+ last line of a included file)
+
+Wed Jan 29 21:13:32 2003
+- Fixed exception handling to report the correct error position
+- Fixed another bug in the stream position calculation scheme
+- Added a more elaborate sample 'list_includes' which lists the dependency
+ information for a given source file (see test/list_includes/readme.txt).
+
+Sat Jan 18 22:01:03 2003
+- Fixed a bug in the stream position calculation scheme
+- Made cpp::exceptions more standard conformant (added 'throw()' at appropriate
+ places)
+- Overall housekeeping :-)
+
+Wed Jan 15 21:54:20 2003
+Changes since project start (still 0.5.0)
+- Added #include <...> and #include "..." functionality
+- pp directives are now generally recognized
+- Decoupled the C++ lexers and the pp grammar to separate compilation
+ units (optionally) to speed up compilation (a lot!)
+
+Thu Jan 2 12:39:30 2003
+A completely new version 0.5.0 of the C preprocessor was started. It's a
+complete rewrite of the existing code base. The main differences are:
+- The preprocessor is now implemented as an iterator, which returns the
+ current preprocessed token from the input stream.
+- The preprocessing of include files isn't implemented through recursion
+ anymore. This follows directly from the first change. As a result of this
+ change the internal error handling is simplified.
+- The C preprocessor iterator itself is feeded by a new unified C++ lexer
+ iterator. BTW, this C++ lexer iterator could be used standalone and is not
+ tied to the C preprocessor. There are two different C++ lexers implemented
+ now, which are functionally completely identical. These expose a similar
+ interface, so the C preprocessor could be used with both of them.
+- The C++ lexers integrated into the C preprocessor by now are:
+ Slex: A spirit based table driven regular expression lexer (the slex
+ engine originally was written by Dan Nuffer and is available as a
+ separate Spirit sample).
+ Re2c: A C++ lexer generated with the help of the re2c tool. This C++
+ lexer was written as a sample by Dan Nuffer too.
+ It isn't hard to plug in additional different C++ lexers. There are plans to
+ integrate a third one written by Juan Carlos Arevalo-Baeza, which is
+ available as a Spirit sample.
+

+ issue is resolved
+- Separated code for dumping a parse tree to XML for inclusion in the main
+ Spirit headers
+
+Thu Jan 17 23:51:21 2002
+Changes from 0.2.1 to 0.2.2:
+- Fixes to compile with gcc 2.95.2 and gcc 3.0.2 (thanks Dan Nuffer)
+- Reformatted the grammars to conform to a single formatting guideline
+- Assigned explicit rule_id's to the rules of cpp_grammar, so that the

+Tue Jan 15 23:40:40 2002
+Changes from 0.2.0 to 0.2.1:
+- Corrected handling of defined() operator
+- In preprocessing conditionals undefined identifiers now correctly
+ replaced by '0'
+- Fixed several const problems
+- Added parse_node_iterator for traversing one node in a parse_tree
+ without going deeper down the hierarchy than one level (this is useful,
