release-1.5.0.8

Build / Distribution

• Added a root CMakeLists.txt defining the header-only Core / Core::Core interface library with C++20 and the appropriate include paths.
• Added a Forge recipe for the Core library, examples, and unit tests, using dotted release build numbers.
• Added automated Forge cbox creation and publication to tagged GitHub releases.

Header Fixes

• FolderHelper.h, StlOperators.h, and Utils.h: Added missing standard-library includes so the headers compile reliably when included on their own.
• StlUtils.h: Marked variables used only by assertions as [[maybe_unused]] to avoid warnings in builds where assertions are disabled.

Tests / Documentation

• Made atan2n() tests tolerant of expected floating-point rounding differences.
• Corrected tag_release.sh command examples in the README and documented the project's historical AI-usage (or policy depending on how you look at it).

release-1.4.0.7

UTF-8 / CP437

• Utf8.h: Renamed lookup_cp437() to the more descriptive unicode_to_cp437().
• Utf8.h: Added cp437_to_unicode() as the reciprocal conversion from CP437 bytes to Unicode code points.
• Utf8.h: Completed and reorganized the CP437 mapping table, including low-area graphical glyphs and 0x2302 -> 0x7F.
• Utf8.h: cp437_to_unicode() now accepts lower bytes.
• Utf8.h: unicode_to_cp437() now validates ASCII-range input symmetrically with cp437_to_unicode().

String Helpers

• StringHelper.h: Added str::is_ascii() and str::is_printable_ascii().
• StringHelper.h: Improved adjust_str() so LeftInteger needle construction uses the target string type's constructor.
• StringBox.h: Only std::string input is split on newline; non-string string types are treated as already-single-line values.

Terminal Detection / Emission

• System.h: Added is_windows_terminal().
• System.h: Replaced the older Windows-cmd check with the more robust is_non_wt_console().
• Term.h: Added use_ansi_renderer(const TermMode&).
• Term.h: Expanded TermMode with richer terminal/font information such as Windows Terminal/conhost classification, font face, TrueType font state, and Windows font class.
• Term.h: Removed static VT-enabled caching so repeated terminal-mode initialization can reflect the current state.

Text I/O

• TextIO.h: Added verbosity arguments to read_file() and write_file().
• TextIO.h: Fixed severity level for failed file-open errors in write_file().

Misc

• StlUtils.h: Added Range and in_ranges() for efficient range membership checks.
• MathUtils.h: Added an integer overload for lerp().
• Updated README API overview for the new helpers and renamed functions.

release-1.3.1.6

• StringHelper.h: For tokenize() I removed the last template argument KeyLambda because it makes little sense when KeyT already works on the level of e.g. t8::Glyph. Better to just compare with it directly.
• Histogram.h: Fixing bug in instantiation of `StringBox object unearthed due to earlier 2 commits.

release-1.3.0.5

• Added unit tests for str::tokenize().
• System.h: Inlining all functions for ODR.
• StringHelper.h: Templatizing rep_str().
• StringHelper.h: Templatizing tokenize().
• StringHelper.h: Templatizing rep_char().
• StringHelper.h: Templatizing adjust_str().
• StringBox.h: Templatizing struct StringBox.

release-1.2.1.4

• Utf8.h: decode_next_utf8_char32() now returns ch32 = none if no valid codepoint was found.
• Added an Examples folder with an examples.cpp that will allow you to browse UTF-8 code point blocks.
• Utf8.h: Adding new function num_utf8_codepoints() which returns the number of glyph/character codepoints that are encoded inside of the supplied std::string.
• Added new header Keyboard.h with cross-platform functions getch(), press_any_key() and press_any_key_or_quit().
• StringHelper.h: Templetizing function hex2int() on return type (default int) which makes it much more useful.
• System.h: Functions is_wsl() and is_windows_cmd() must both be marked inline for the static "one call" scheme to be safe.
• StringHelper.h: Improved to_lower() / to_upper() functions and adding more variants for a more complete API. Also added a few unit tests for these.
• StringHelper.h: Added new function rep_str() akin to rep_char().
• Rand.h: Fixed bug in rand_enum() that caused the last element before NUM_ITEMS to never be returned.
• StringHelper.h: Adding lenI() overloads for std::string, const char*, std::wstring_view, std::wstring and const wchar_t*.
• Added new header Term.h containing the functions: inline bool is_console_stdout(), inline bool enable_vt_on_stdout(), inline std::wstring utf8_to_utf16(std::string_view s), inline void write_console_w(std::wstring_view ws), inline void write_console_a(std::string_view s), inline TermMode init_terminal_mode(int requested_codepage), inline bool use_ansi_colors(const TermMode& m), inline void emit_text(const TermMode& m, std::string_view s_utf8, std::string_view s_bytes_for_legacy = {}) and inline void emit_text_nl(const TermMode& m, std::string_view s_utf8, std::string_view s_bytes_for_legacy = {}).

release-1.1.1.3

• Fixed bug in utf8::encode_char32_codepage() that caused an ASCII character to be unidentified if passiung argument codepage = 437.

release-1.1.0.2

• Added new header Utf8.h with some useful functions for encoding utf-8 bytes to and from an std::string object.

release-1.0.1.1

• Fixed windows warning in Histogram.
• Added version.h to the xcode project.

release-1.0.0.0

• First release.
