* Replace calls to boost::forward with calls to std::forward.
<boost/parameter/config.hpp>
* Relax perfect forwarding requirements so that msvc-12.0 passes muster.
<boost/parameter/parameters.hpp>
* Use boost::mpl::vector if neither boost::fusion::list nor boost::fusion::deque are true variadic MPL sequences.
.travis.yml
appveyor.yml
* Remove test configurations of compilers that fail perfect forwarding requirements.
* Consolidate for fewer jobs.
1. The end of section 3.2.1 of the current home page tutorial notes "that because of the forwarding problem, parameter::parameters::operator() can't accept non-const rvalues." Add code to eliminate this problem. As a positive side effect, Boost.Parameter-enabled functions and constructors are no longer bound by BOOST_PARAMETER_MAX_ARITY on compilers that support perfect forwarding. User code can now check for this support by detecting the configuration macro BOOST_PARAMETER_HAS_PERFECT_FORWARDING, or manually turn off this support by defining the configuration macro BOOST_PARAMETER_DISABLE_PERFECT_FORWARDING. See "test/evaluate_category.cpp" and "test/preprocessor_eval_category.cpp" for example usage.
2. Add parameter category qualifiers "consume" and "move_from"(current qualifiers are "in", "out", "in_out", and "forward") based on http://www.modernescpp.com/index.php/c-core-guidelines-how-to-pass-function-parameters.
3. Update documentation to reflect the above changes.
<boost/parameter/parameters.hpp>:
* Add preprocessor conditional statement to prevent generation of ill-formed function call operator overloads.
"test/maybe.cpp"
"test/singular.cpp"
"test/tutorial.cpp"
"test/sfinae.cpp"
"test/earwicker.cpp"
* Replace BOOST_PARAMETER_KEYWORD statements with BOOST_PARAMETER_NAME statements.
"test/optional_deduced_sfinae.cpp"
"test/normalized_argument_types.cpp"
"test/literate/*.cpp"
* Use Boost.Core.LightweightTest where int main() is available.
* Replace assert statements with BOOST_TEST_EQ statements.
"test/basics.hpp"
* Remove preprocessor statements regarding borland, gcc-2, and msvc workarounds.
"test/ntp.cpp"
"test/sfinae.cpp"
"test/earwicker.cpp"
"test/normalized_argument_types.cpp"
"test/basics.hpp"
* Add preprocessor conditional statement to #error out if BOOST_PARAMETER_MAX_ARITY is set to an insufficient value.
"test/basics.cpp"
"test/deduced.cpp"
"test/macros.cpp"
"test/preprocessor.cpp"
"test/preprocessor_deduced.cpp"
* Replace S and char const* expressions with boost::container::string expressions.
* Uncomment any code that fails to compile, but add preprocessor conditional statement so that test suites can incorporate compile-fail statements regarding the code in question.
* Ensure that int main() returns boost::process_errors().
"test/literate/deduced-template-parameters0.cpp":
"test/literate/exercising-the-code-so-far0.cpp":
* Enclose BOOST_MPL_ASSERT statements within MPL_TEST_CASE block.
"test/literate/defining-the-keywords1.cpp":
* Add graphs::tag::graph::qualifier type definition because perfect forwarding code will check for it.
* Replace deprecated keyword::get() invocation with keyword::instance invocation.
test/Jamfile.v2:
* Add modifier <define>BOOST_PARAMETER_MAX_ARITY=# to run, run-fail, compile, and compile-fail statements to conserve compiler memory usage on GitHub's side.
* Add modifier <preserve-target-tests>off to run and run-fail statements to conserve executable space on GitHub's side.
* Separate bpl-test statement into its own target, parameter_python_test, which fails on xcode8.3 as well as on mingw and msvc compilers with address-model=64.
* The next commit (which will implement perfect forwarding) will subsume test/literate/Jamfile.v2 into this file. Strangely enough, attempting to do so now will result in compiler errors.
.travis.yml:
* Add g++-4.7, g++-4.8, g++-4.9, clang++-3.5, clang++-3.6, clang++-3.7, clang++-3.8, clang++-3.9, clang++-4.0, xcode7.3, and xcode8.3 compiler configurations.
* Split compiler configurations by available CXXSTD values. (This will keep the job times within limits for the next commit.)
* Ensure that the xcode8.3 compiler configurations exclude parameter_python_test from the test suite.
appveyor.yml:
* Add compiler configurations that support address-model=64 to the test matrix.
* Ensure that the new configurations exclude parameter_python_test from the test suite.
Add parameter category qualifier "forward" (current qualifiers are "in", "out", and "in_out") based on http://www.modernescpp.com/index.php/c-core-guidelines-how-to-pass-function-parameters. Add new usage syntax BOOST_PARAMETER_NAME((object-name), namespace-name) qualifier(tag-name)) and BOOST_PARAMETER_NAME(qualifier(name)). (Existing code that uses qualifiers directly and correctly with BOOST_PARAMETER_FUNCTION and other code generation macros should remain unaffected for now, so no breaking changes.) The reason for the change in usage is to enable applying of parameter category constraints to Boost.Parameter-enabled functions and constructors invoked through argument composition. (Otherwise, it is currently possible to use argument composition to bypass parameter category constraints applied in BOOST_PARAMETER_FUNCTION et. al.) See "test/compose.cpp" for example usage.
* Add code generation macros BOOST_PARAMETER_FUNCTION_CALL_OPERATOR and BOOST_PARAMETER_CONST_FUNCTION_CALL_OPERATOR to <boost/parameter/preprocessor.hpp>.
* Also, add documentation for BOOST_PARAMETER_CONST_MEMBER_FUNCTION, BOOST_PARAMETER_BASIC_FUNCTION, BOOST_PARAMETER_BASIC_MEMBER_FUNCTION, and BOOST_PARAMETER_BASIC_CONST_MEMBER_FUNCTION.
Document that boost::parameter::required, boost::parameter::optional, and boost::parameter::deduced are defined in their own header files, which are in turn #included by <boost/parameter/parameters.hpp>.
<boost/parameter/name.hpp>:
* Move support metafunction definitions and BOOST_PARAMETER_TAG_PLACEHOLDER_TYPE macro definition to <boost/parameter/aux_/name.hpp>.
* Move BOOST_PARAMETER_IS_BINARY macro definition to <boost/parameter/aux_/preprocessor/is_binary.hpp>.
* Use BOOST_PARAMETER_TAG_PLACEHOLDER_TYPE macro.
<boost/parameter/aux_/arg_list.hpp>:
Move forward declarations to their own header files.
<boost/parameter/aux_/tagged_argument.hpp>:
* Move boost::parameter::aux::tagged_argument_base, boost::parameter::aux::is_tagged_argument_aux, and boost::parameter::aux::is_tagged_argument to <boost/parameter/aux_/is_tagged_argument.hpp>
* Remove unnecessary forward declarations.
<boost/parameter/parameters.hpp>:
* Move support metafunction definitions to their own header files in directory boost/parameter/aux_/pack.
* Move support macro definitions to <boost/parameter/aux_/preprocessor/no_perfect_forwarding_begin.hpp> and their corresponding #undef statements to <boost/parameter/aux_/preprocessor/no_perfect_forwarding_end.hpp>.
<boost/parameter/aux_/overloads.hpp> works at the preprocessor level, so move to <boost/parameter/aux_/preprocessor/overloads.hpp>.
<boost/parameter/preprocessor.hpp>:
* Move voidstar type definition to <boost/parameter/aux_/void.hpp>.
* Move support metafunctions to their own header files in directory boost/parameter/aux_/pp_impl.
* Move support macros to header files in directory boost/parameter/aux_/preprocessor/impl.
test/compose.cpp:
Change workarounds from boost::function to std::function since msvc-11.0 reports having a C++11-compliant <functional> header.
Add LIBS_PARAMETER_TEST_RUN_FAILURE configuration macro to facilitate run-fail testing.
test/Jamfile.v2:
Replaced deprecated test-suite statement with alias statements.
Added run-fail test case under its own alias statement.
appveyor.yml:
Add mingw compiler configurations to the test matrix.
Update msvc-11.0 configuration to also execute the run-fail test.
travis.yml:
Ensure that only the standard tests are run, not the run-fail test.
