https://pypi.org/project/ogopego/ ## [v0.1.13] 2026-06-14 New syntax + optimized grammar models ### Added - New `@name`, `@int`, `@uint`, `@float`, `@bool` meta-expressions for typed token matching (names, signed/unsigned ints, floats, bools) - `Cursor.MatchName`/`MatchInt`/`MatchUInt`/`MatchFloat`/`MatchBool` methods on `RuneCursor` and `StrCursor` - `Ctx` interface methods that delegate to cursor matching - Five concrete model types (`NameMeta`, `IntMeta`, `UIntMeta`, `FloatMeta`, `BoolMeta`) with `MetaExp` base - Full compilation pipeline: EBNF tree compile, JSON import/export, analysis passes, display (pretty-print & railroads) - 40 cursor-level tests ported from TatSu - Boot grammar usage of `@name` in rule definitions ### Changed - Meta expression dispatch updated from single `*MetaExp` type case to five individual type cases across the compiler pipeline - All TatSu `@` meta features brought to parity with TatSu v5.21.1 ### Changed - Refactored grammar semantics from function type (`SemanticsFunc`) to `GrammarSemantics` interface in `pkg/config`; replaced `GrammarParserSemantics` with `EBNFGrammarSemantics` struct adding meta-expression node production (`NameMeta`, `IntMeta`, `UIntMeta`, `FloatMeta`, `BoolMeta`) during boot grammar compilation of `@` expressions -- Juancarlo Añez mailto:apalala@gmail.com
