[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.
