v1.11.4

• additions:
  • include/stlsoft/conversion/char_conversions.hpp — multibyte2wide and wide2multibyte call stlsoft_C_mbstowcs() / stlsoft_C_wcstombs(), and still stamp the NUL at [size];
  • include/stlsoft/error/error_desc.hpp and include/acestl/shims/access/string/time_value.hpp — the wide error_desc fallback and both wide invoke_ACE_OS_snprintf() overloads call stlsoft_C_mbstowcs();
  • include/stlsoft/iterators/common/string_concatenation_flags.hpp — stlsoft::string_concatenation_flags gained None (0x0000);
  • include/stlsoft/shims/access/string/std/exception.hpp and include/stlsoft/shims/access/string/std/type_info.hpp — the wide shims call stlsoft_C_mbstowcs(). The private mbstowcs_() and mbstowcs_len() helpers are gone;
  • include/stlsoft/string/encoding/mbstowcs.h and include/stlsoft/string/encoding/wcstombs.h — stlsoft_C_mbstowcs() / stlsoft_C_wcstombs() take a destination capacity and a source limit, hide mbstowcs_s() / wcstombs_s(), and return a count that excludes the NUL. A null destination is the length probe;
  • include/stlsoft/util/exception_string_creator.hpp — wide_to_multibyte_or_throw_() calls stlsoft_C_wcstombs(). This is the last call site outside the encoding headers;
  • include/unixstl/system/system_traits.hpp and include/unixstl/system/directory_functions.h — system_traits<wchar_t>::get_environment_variable() and unixstl_C_get_home_directory_w() call stlsoft_C_mbstowcs() / stlsoft_C_wcstombs(). A short home-directory buffer still returns cchBuffer - 1;
• refactoring:
  • include/acestl/shims/access/string/time_value.hpp — the non-ACE_USES_WCHAR wide invoke_ACE_OS_snprintf() wrote the mbstowcs() result at &s2[2]; it now writes at s2, matching the wide-ACE overload;
  • include/rangelib/integral_range.hpp — invalid_integral_range_policy::operator() formats the std::out_of_range message with stlsoft_C_snprintf(); the 64-bit helpers take the format from printf_traits<>::decimal_format_a(). The exception text is unchanged;
• compatibility:
  • Output-iterator deref_proxy types declare an explicit copy constructor, so C++11 and C++14 no longer deprecate the implicit one when copy assignment is deleted (-Wdeprecated-copy under -Werror). Copy assignment stays deleted. include/stlsoft/iterator/associative_eraser_iterator.hpp, include/stlsoft/iterator/eraser_iterator.hpp, include/stlsoft/iterator/FILE_iterator.hpp (the constructor is present in every dialect; it had been guarded on C++11), include/stlsoft/iterator/push_insert_iterator.hpp, include/stlsoft/iterator/string_insert_iterator.hpp, include/stlsoft/iterators/c_str_inserter.hpp, include/stlsoft/iterators/cstring_concatenator_iterator.hpp, include/stlsoft/iterators/null_output_iterator.hpp, include/stlsoft/iterators/ostream_iterator.hpp, include/stlsoft/iterators/string_concatenator_iterator.hpp, and include/stlsoft/iterators/unary_function_output_iterator_adaptor.hpp;
  • C functions with no parameters are prototyped as (void): stlsoft_C_count_functions_get_8bit_table() in include/stlsoft/util/bits/count_functions.h, and unixstl_C_path_classify_alwaysInvalidChars_X_() in include/unixstl/filesystem/path_functions/classify_functions_X_.h;
• testing:
  • test.scratch.versions.stdio colours headings (magenta), names (blue), versions and VER values (green), and macro names (cyan) through woad when --use-woad is set, matching test.scratch.versions.iostreams; plain text when woad is not opted in;
  • test.unit.acestl.shims.access.string.time_value — wide shims c_str_len_w, c_str_data_w, c_str_ptr_w, and c_str_ptr_null_w match the locale conversion of the narrow text;
  • test.unit.rangelib.invalid_integral_range_policy locks those messages, including the 32-bit and 64-bit extremes, and checks that a non-closing integral_range throws the same text. The caught result is recorded before the assertion, so a non-returning policy call is not followed by unreachable code under MSVC (C4702);
  • test.unit.stlsoft.conversion.char_conversions — multibyte2wide / wide2multibyte: ASCII, empty, counted, round-trip, a string longer than the internal buffer, and rejection when the C library rejects the input;
  • test.unit.stlsoft.error.error_desc — error_desc_w matches mbstowcs() of the narrow strerror() text on the fallback path; a _wcserror / _wcserror_s build records a pass;
  • test.unit.stlsoft.std.exception — the narrow shims are exception::what(); c_str_data_w, c_str_len_w, c_str_ptr_w, and c_str_ptr_null_w match the ASCII widening of that message, and an empty what() yields an empty wide string and a null c_str_ptr_null_w;
  • test.unit.stlsoft.std.type_info — the narrow shims are type_info::name(); c_str_data_w, c_str_len_w, c_str_ptr_w, and c_str_ptr_null_w match the ASCII widening of that name;
  • test.unit.stlsoft.string.encoding — ASCII success, length probe, exact fit, counted source, zero capacity, short buffer, "count excludes the NUL", and rejection for stlsoft_C_mbstowcs() / stlsoft_C_wcstombs();
  • test.unit.stlsoft.util.exception_string_creator — wide append() (string, character, counted, and after a narrow prefix) and create();
  • The rejection oracles in test.unit.stlsoft.conversion.char_conversions and test.unit.stlsoft.util.exception_string_creator call mbstowcs_s() / wcstombs_s() when STLSOFT_USING_SAFE_STR_FUNCTIONS is set;
• build:
  • batch_compile_check, check_unit_test_names.rb, and generate_cmakelists.rb moved from dev/bin to .dev/bin;
  • .dev/bin/batch_compile_check (the human-driven bulk smoke-test script):
    • compiles each header with -fsyntax-only (no object files). A failed compilation exits 1 and lists FAIL: <header> (C|C++, <std>). A missing include directory, a missing subproject directory, an unknown compiler, a missing option value, an unrecognised language version, or zero matching headers also exits 1. SIGINT exits 130 and stops jobs still running;
    • --c-language-version and --cxx-language-version are independent. C accepts 89, 90, 99, 11, 17, 20, and 23 (default 17). C++ accepts 98, 03, 11, 14, 17, 20, and 23 (default 98, 03, 11, 14, 17, and 20; 23 is selectable and is not in the default sweep). A version flag for the language excluded by -C or -C++ is an error;
    • -j / --jobs compiles up to N headers at once (default 1, a positive integer). Failures stay in the order the compilations were started. With one job the compiler's diagnostics stay on the terminal; with more than one they are kept only for failures;
    • Every compile passes -Wall -Wextra -pedantic. -W / --werror adds -Werror;
    • Skip markers are whole /* STLSOFT:… */ comments, read once per header and matched case-insensitively: STLSOFT:FILE_DEPRECATED, STLSOFT:FILE_EXCEPTED, STLSOFT:FILE_NOT_SELF_SUFFICIENT, and per-standard STLSOFT:<std>:FILE_DEPRECATED / FILE_EXCEPTED. STLSOFT:Windows:FILE_EXCEPTED applies only when not on Windows. --counts reports files found and skipped separately from compilation attempts, failures, and per-version skips;
    • Headers are discovered with NUL-delimited find and listed in LC_ALL=C order. comstl and winstl are rejected when not on Windows, before any verbose configuration is printed. On Windows, comstl and inetstl are compiled after windows.h, and winstl also after ntsecapi.h;
  • .dev/bin/check_unit_test_names.rb (0.3.0) checks File: labels and XTESTS_START_RUNNER* names. --mode selects both, file, or runner (default both). A File: label under examples or test is the project-relative path. A runner name, for test/unit and test/component programs named entry.c or entry.cpp, is that directory with / replaced by .; __FILE__ is accepted. --project-root / -R selects the tree (the default is two levels above the script). Either mismatch count exits 1. The Check test names job runs the script once on Ubuntu over examples and test;
  • Gemfile.lock records clasp-ruby 0.23.4, libclimate-ruby 0.17.4, recls-ruby 2.13.5, and xqsr3 0.39.11, and adds the arm64-darwin-25 platform;
• documentation and boilerplate:
  • INSTALL.md archive examples name STLSoft-1.11.4;
  • File: labels under test and examples use the project-relative path;
  • Doxyfile PROJECT_NUMBER is 1.11.4;
  • README.md New in 1.11 lists stlsoft/string/encoding/mbstowcs and stlsoft/string/encoding/wcstombs;
  • include/unixstl/unixstl.h — the _UNIXSTL_VER_1_8_6* comments name 1.8.6 (they had said 1.8.8);
• version:
  • _STLSOFT_VER is 1.11.4 (_STLSOFT_VER_1_11_4 = 0x010B04FF); test.unit.versions asserts it. No subproject composite version changed;
