## Spirit Change Log

## 1.8.6

- Fixed a integer overflow bug preventing to fail parsing on certain large integers. This bug was reported and fixed by Michael Andersen Nexø

## 1.8.5

- For performance reasons, leaf_node_d/token_node_d have been changed to implicit lexems that create leaf nodes in one shot. The old token_node_d is still available and called reduced_node_d, now.
- It's now possible to phoenix::bind (version 1) symbols::add.

## 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

- 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

## 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
