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. +- Fixed documentation of the different language_support flags. +- The support for long long suffixes is no longer bound to the variadics mode, + 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 + included files containg a "include_" in their name. +- 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 + about #include_next directives as well. +- Separated the different lexer tests. +- Fixed a bug in the whitespace eater. +- Fixed a bug where Wave emitted the found C++ comments in --preserve mode even + if these were found inside of disabled #if/#endif blocks. +- Removed the function local static grammars to avoid possible raise conditions + 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. +- Added special handling of the eof tokens inside the lexer iterator classes + for Comeau. +- Applied a workaround proposed by David Abrahams to make the slex lexer work + on the CodeWarrior platforms. + +Sun May 8 17:22:59 WEDT 2005 +Version 1.1.17 +- Added ill_formed_character_literal and ill_formed_integer_literal errors. +- Improved error handling and diagnostics for integer overflow in #if/#elif + expressions. +- Fixed a bug in the testwave application which prevented the correct + recognition of expected errors under certain circumstances. +- Fixed a portability problem (for gcc 3.3.x) in the testwave application. +- Enforced that #if/#endif are balanced file wise. +- Changed the command line arguments for the Wave testrun to use absolute + directories. +- Changed the test application to return a value != zero if one of the given + config files were not found. +- Fixed a command line parsing problem caused by a change in the parameter + handling inside in the program_options library. +- Switched to the most recent version of re2c (V0.9.7.dev). +- Fixed a como compilation error and several como --a warnings. +- The T_EOF token doesn't carry the value of the previous token anymore. +- Added operator==() to the token classes to fix the ambiguity error reported + by the True64 compiler. +- Improved the error message, when empty arguments are used in pure C++ mode. +- Added character literal out of range testing and an additional corresponding + error message. +- Fixed parsing of long character literals (such as '\x1234'). +- Fixed almost all problems diagnosed by the Boost inspection report. +- Several fixes to make the True64 compiler happy. +- Added the long long suffix handling to the C99 mode (LL/ll). +- 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. + + std::string flex_string const_string const_string + 12 Byte 28 Byte + arithmetic.cpp 2.543 1.742 0.951 1.001 + array.cpp 2.453 1.762 0.951 1.011 + comparison.cpp 0.560 0.340 0.270 0.280 + control.cpp 0.590 0.340 0.290 0.300 + debug.cpp 0.370 0.310 0.190 0.190 + detection.cpp 0.050 0.060 0.030 0.030 + extended.cpp 0.370 0.260 0.190 0.190 + facilities.cpp 0.610 0.340 0.290 0.300 + iteration.cpp 1.081 0.550 0.410 0.450 + list.cpp 1.742 1.141 0.811 0.851 + logical.cpp 0.070 0.200 0.040 0.040 + punctuation.cpp 0.030 0.080 0.020 0.020 + repetition.cpp 1.392 0.851 0.650 0.690 + selection.cpp 0.440 0.270 0.210 0.220 + slot.cpp 0.680 0.350 0.240 0.270 + tuple.cpp 0.420 0.240 0.190 0.210 + + +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.

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"'.

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. + +------------------------------------------------------------------------------- +Tue Feb 12 22:29:50 2002 +Changes from 0.2.3 to 0.2.4: +- Moved XML dumping functions to the main Spirit directory +- Fixed operator '##', it was not correctly implemented somehow :-( + +Sun Feb 10 21:07:19 2002 +Changes from 0.2.2 to 0.2.3: +- Implemented concatenation operator '##' (cpp.concat) +- Removed defined() functionality for Intel compiler (it ICE's) until this + 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 + access code to the embedded definition class is not needed anymore +- Fixed a remaining const problem + +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, + if all inspected tokens arranged along a single node in the parse tree. + The main difference to the parse_tree_iterator is, that the underlying + iterator generally can be adjusted correctly after advancing the attached + parse_node_iterator +- Fixed a problem with gcc 2.95.2, which doesn't have a <sstream> header +- Prepared usage of slex for lexer states + +Sun Jan 13 10:21:16 2002 +Changes from 0.1.0 to 0.2.0: +- Added operator 'defined()' +- Added directive '#warning' +- Corrected error reporting +- Added command line option -I- for finer control of the searched include + directories (-I and -I- should now work as in gcc, see readme.html for + more info) +- Corrected conditional preprocessing (should be fully functional now) +- Fixed existing code base for changes made in parse tree support +- Moved parse tree utility functions to a separate header (prepared for + inclusion to the Spirit main library) |
