<!-- Copyright (c) 2017-2026 Juancarlo Añez (apalala@gmail.com) SPDX-License- Identifier: BSD-4-Clause --> [V5.23.0] NEW FEATURES + BUGFIXES + (- DEPENDENCIES) ADDED * Added --generate-parser option to the cling CLI tool. * Added tatsu.util.barz — self-contained progress bar rendering (replaces * rich.progress). * Added tatsu.util.treez — self-contained dependency tree rendering (replaces * rich.tree). * Added tests/tree_test.py. * Added g2e, bench, and ideps subcommands to cling CLI — all tools now * invocable through cling. * Added add_argparse_options(parser) pattern to bench.py, ideps.py, g2etool.py * for uniform CLI interface. * Added tatsu.ztyle.markup — Rich-style markup parser ([bold]text[/], * [red]...[/all]). Parse with markup() → returns StyleZ (a str subclass * wrapping list[Style]; styles via .style property). Optionally pass a color * policy. * Added Style.from_raw() — reconstruct a Style from an ANSI escape string * (e.g. "\e[31mhello\e[0m") for roundtrip support. * Added Style.apply_style() — applies ANSI rendering to an arbitrary string * directly. * Added tatsu.util.tty — shared TTY/ANSI utilities (ANSI_RE, SGR_RE, * tty_escape, tty_unescape, descape, visual_len, cursor hide/show, pushup, * blankpad). * Added etc/RICH_MARKUP.md — specification for the Rich-style markup syntax. * Added Style.__json__() protocol — Style now serializes through * asjson/fromjson (any object with __json__ method is supported). * Added tatsu/packetz/ — inter-task communication via filesystem-based message * passing queues that work across threading and multiprocessing. * Added tatsu/barz/ — self-contained progress bar rendering with ztyle * coloring support and a single background rendering thread. * Added rich dependency removed from core: pygments optional for colored cling * output; graphviz optional for graphical diagrams (text-based railroad * diagrams remain default). CHANGED * No more colorama: All mentions of colorama removed. The project consistently * uses its own ztyle library. * No more rich dependency: cling CLI no longer pulls in rich. Progress bars * use tatsu.util.barz. Dependency trees use tatsu.util.treez. Summaries use * ztyle. * colorize module renamed to ztyle to avoid confusion with the colorize * package on PyPI. * tatsu.grammars renamed to tatsu.peg (kept grammars.py shim). * tatsu.api moved into its own tatsu.api package. * ideps.py refactored to use own Tree + Style instead of rich.tree. * bench.py, ideps.py, g2etool.py migrated from ad-hoc argument parsing to * add_argparse_options(parser) + main(parser) -> int. * Bar metrics refactored: Metrics class with lazy @cached_property per column; * BarRowData base class extracted to break circular dependency; Col enum moved * to own module. * tatsu/util/escapes.py renamed to tatsu/util/tty.py with expanded API (cursor * controls, pushup, blankpad, etc.). * Style.__repr__ now uses \e notation consistently and encodes fmt specs for * roundtrip via f{...:...}. * Style.__len__ uses visual_len() from util.tty (ignores ANSI escapes in * length). * packetz serialization simplified: removed hash validation; __class__ * compressed to @ in JSON. * barz.BarRow switched from private accessors to public attributes; * stop_on_complete → selfstop. * parproc.task uses PacketzQueue directly instead of init_queue() helper. FIXED * Fixed: Group no longer optimized away if Group.exp contains non-leaf nodes. * The optimization made EBNF representation semantically incorrect. Re- * introducing a group for --pretty had several special cases (group if part of * Sequence, Named, ...). * Fixed: Exporting cling CLI no longer pulls in rich as a dependency. * Fixed: ANSI escape utilities no longer duplicated across ztyle.style and * packetz.packet; consolidated in util.tty. -- Juancarlo Añez mailto:apalala@gmail.com
