Spirit Change Log

1.8.4

• Fixed no_actions bug where no_action is applied recursively.
• Fixed the regex_p parser for Boost >= V1.33.0
• Implemented a workaround for namespace issues VC++ has with Spirit's file_iterators
• Fixed bug in tree match policies that prevented using gen_pt/ast_node_d, reported by Jascha Wetzel.
• Made position_iterator usable with wchar_t based strings.

1.8.3

• Config correction for Sun C++ by Steve Clamage (see this link).
• Fixed multi_pass_iterator for 64 platforms, where sizeof(int) != sizeof(ptr_type).Fixed bug that prevents the use of closures with grammars with multiple entry points, reported by David Pierre
• Fixed bug that prevented embedding of grammars with multiple entry points, reported by David Pierre
• Added '\0' to the set of valid escaped characters for escape_ch_p.
• Fixed a switch_p bug when used with a phoenix::actor as the conditional expression.
• __LINE__ macro now gets expanded in BOOST_SPIRIT_ASSERT_EXCEPTION
• Fixed a bug in the intersection parser reported by Yusaku Sugai
• The symbol parser uses the null character internally. Checks were added so that:
  • tst.add asserts if string contains the null character
  • tst.find doesn't match null characters in the input
• Fixed match_attr_traits.ipp to allow non-POD to pass through. The previous version taking in the ellipsis "..." does not allow PODs to pass through.
• Allow evaluation to int as condition to if_p parser.
• Applied performance improvement changes to the PT/AST code as suggested by Stefan Slapeta.
• Fixed several problems with AST tree node directives (inner_node_d[], discard_first_node[], discard_last_node[] and infix_node_d[]).

1.8.2

Maintenance release (almost the same as 1.8.1 plus a few fixes here and there)

• Added specializations to str_p and ch_p to allow str_p('c') and ch_p("c") thus fixing some non-bugs
• Fixed bug where a match<T> is a variant.
• added Jamfile/Jamrules from CVS to spirit-1.8.1/
• added boost-build.jam from boost to spirit-1.8.1/
• disabled template multi-threading in libs/spirit/test/Jamfile
• added a boost-header-include rule (from spirit-header-include) pointing to miniboost in libs/spirit/test/Jamfile
• Fixed if_p inconsistency

1.6.2

The Spirit 1.6.2 release is a bug-fix release only, no new features were introduced.

• wchar_t friendly implementation of graph_p
• Modified escape_char_parser::parse() to use a static parser instead of a rule. This will make it more friendly to use in trees. It should also be a little more efficient.
• Moved to Boost Software license 1.0.
• workaround for Error 322 name lookup in base class specialization finds type
• fixed limit_d bug
• [numerics] Workaround for aC++
• Fixed a bug in the switch_p parser.
• Fixed a EOI problem in multi_pass
• added Jamfile/Jamrules from CVS to spirit-1.6.1/
• added boost-build.jam from boost to spirit-1.6.1/
• disabled template multi-threading in libs/spirit/test/Jamfile
• added a boost-header-include rule (from spirit-header-include) pointing to miniboost in libs/spirit/test/Jamfile

1.8.1 (Released with Boost 1.32.0)

The Spirit 1.8.1 release is a bug-fix release only, no new features were introduced.

• Spirit now requires at least Boost 1.32.0 to compile correctly
• Removed the support for the older iterator adaptor library and
• Moved to use the new MPL library
• Spirit was moved to use the Boost Software License 1.0.
• Fixed several parsers to support post-skips more correctly.
• Fixed a no_node_d[] bug.
• Fixed a bug in shortest_d[].
• Fixed a bug in limit_d[].
• Fixed parser traversal meta code.
• Fixed several bugs in switch_p.
• Fixed AST generating problems, in particular with the loops related parsers.
• Fixed several bugs in the multi_pass iterator.
  • Fixed a problem, when the used base iterator returned a value_type and not a reference from its dereferencing operator.
  • Fixed iterator_traits problem
  • Fixed an EOI problem
  • Fixed a bug, when used with std::cin
• Found a bug in grammar.ipp when BOOST_SPIRIT_SINGLE_GRAMMAR_INSTANCE is defined
• Rewritten safe_bool to use CRTP - now works also on MWCW, fixed several bugs with the implementation.
• Fixed and extended the debug diagnostics printed by the parse tree code.

1.8.0 (Released with Boost 1.31.0; Includes unreleased 1.7.1)

• Fixed a wchar_t problem in the regex_p parser.
• removed code and workarounds for old compilers (VC6/7 and Borland)
• Changed license to the new boost license.
• Modified escape_char_parser::parse() to use a static parser instead of a rule. This will make it more friendly to use in trees. It should also be a little more efficient.

1.7.1 (Unreleased; becomes 1.8.0)

• Added a full suite of predefined actors.
• Moved rule_alias and stored_rule from core/non-terminal to dynamic.
  Made as_parser a public API in meta/as_parser.hpp
• Separated Core.Meta into its own module
• Refactored Utility module
  Moved some files into Utility.Parsers

• utilities
  • parsers
    • chset, regex, escape_char
      confix, list, distinct
      functor_parser
• support
  • scoped_lock
    flush_multi_pass
    grammar_def
• actors
  • assign

• Stored rules
• Added the switch_p and select_p dynamic parsers.
• Multiple scanner support for rules.
• The Rule's Scanner, Context and Tag template parameters can be specified in any order now. If a template parameter is missing, it will assume the defaults. See test/rule_tests.cpp.
• Introduced the possibility to specify more than one start rule from a grammar.
• Added an implementation of the file_iterator iterator based on the new Boost iterator_adaptors (submitted originally by Thomas Witt).

[The transition to the new iterator_adaptors should be complete now.]

• Added an implementation of the fixed_size_queue iterator based on the new Boost iterator_adaptors.
• wchar_t friendly implementation of graph_p
• made the copy-constructor and assignment-operator of parser_error_base public to clear VC7.1 C4673 warning. Added copy-constructor and assignment operator to parser_error for clarity of intent.

1.7.0

• assign(string) semantic action now works in VC6
• parsers need not be default constructible
• simplified aggregation of binary and unary parsers (more compiler friendly)
• epsilon workarounds for VC++
• match's attribute now uses boost.optional
• subrules can now have closures
• project wide 64 bit compatibility
• dynamic_parser_tag, reissue of rule.set_id(id);
• numerous primitives improvements and workarounds for problematic compilers
• proper complement (~) of single char parser primitives and chsets
• intuitive handling of lexeme_d
• wide_phrase_scanner_t typedef
• dynamic parser improvements (better support for more compilers)
• complete rewrite of the file_iterator (using boost.iterator_adapters). Supports memory maps wherever available
• multi_pass updates (compatibility with more compilers (e.g VC7) and more)
• position_iterator improvements
• better phoenix support for more compilers
• phoenix new_(...) construct
• new lazy_p parser
• utility.distinct parser (undocumented)
• chset operators improvements
• confix_p streamlining and improvements
• numerous Boost integration improvements

Bug fixes (1.7.0 and 1.6.0)

• Fixed. Using MSVC++6 (SP5), calling the assign action with a string value on parsers using the file_iterator will not work.
• Fixed: using assign semantic action in a grammar with a multi_pass iterator adaptor applied to an std::istream_iterator resulted in a failure to compile under msvc 7.0.
• Fixed: There is a bug in the "range_run<CharT>::set (range<CharT> const& r)" function in the "boost\spirit\utility\impl\chset\range_run.ipp".
• Fixed: handling of trailing whitespace bug (ast_parse/pt_parse related)
• Fixed: comment_p and end of data bug
• Fixed: Most trailing space bug:
• Fixed:
  chset<>::operator~(range<>) bug
  operator&(chset<>, range<>) bug
  operator&(range<>, chset<>) bug
• Fixed: impl::detach_clear bug
• Fixed: mismatch closure return type bug
• Fixed: access_node_d[] and access_match_d[] iterator bugs
• Fixed a bug regarding threadsafety of Phoenix/Spirit closures.
• Added missing include files to miniboost
