v5.21.1 Update#

Added#

  • @name, @int, @uint, @float, @bool meta-expressions for typed matching (identifiers, signed/unsigned integers, floating point literals, and boolean literals)

  • FailedMeta exception for @ meta failures

  • @name now matches identifiers starting with _

  • -z / --optimize CLI option to optimize the grammar model before generating output

Changed#

  • Cache optimized grammar models; inline single-element sequences and call chains in Rule.optimized()

  • Cursor/Text protocols moved from input/text.py → input/cursor.py

  • Versioning via uv-dynamic-versioning; _version.py reads from importlib.metadata

  • CI: upgrade to checkout@v6, setup-uv@v7, setup-python@v6; all dependencies via uv sync

Removed#

  • Deprecated override_single_deprecated (bare @ as override) from grammar and boot parser to allow the symbol to be used for the new meta-expressions
