Changed the schedule composition keyword from "extends" to "modifies"
to better reflect the semantic meaning of schedule inheritance. When
a schedule modifies another, it inherits base blocks and can override
them by name or add new blocks.
This is a breaking change for all existing Storybook files that use
schedule composition. The migration is a simple find-and-replace:
schedule X extends Y → schedule X modifies Y
Changes include:
- Grammar: Updated tree-sitter grammar and lexer token
- Parser: Updated lalrpop parser and AST field names
- Documentation: Updated all reference docs, tutorials, and specs
- Examples: Updated baker-family example schedules
- Tests: Updated all test cases and corpus files
- Testing: Added type system keywords to prop_tests exclusion list
- Tooling: Added xtask for workspace cleanup
- Version: Bumped to v0.3.1 (skipping v0.3.0)
- Spec: Created SBIR v0.3.1 spec documenting the change
BREAKING CHANGE: The "extends" keyword for schedules has been
replaced with "modifies". Update all schedule declarations.
The tests were using line: 2 but the character declarations were on
line: 1 (due to the leading newline in the raw string literal). This
caused the cursor position to be outside the character span, making
the code actions fail to trigger.
Fixed by changing line: 2 to line: 1 in both test_convert_species_to_template
and test_convert_template_to_species.
Added optional requires clause to life_arc declarations:
life_arc Baker requires { skill_level: Number } { ... }
Includes new FieldRequirement AST type, requires keyword token,
and parser support for the requires clause.
Added optional species_base field to Template struct enabling
template-species inheritance syntax: `template Name: Species { ... }`.
Updated LALRPOP grammar and all Template construction sites.
Changed sub_concept syntax from heuristic parent extraction to
explicit dot notation: `sub_concept Parent.Name { ... }`
The old syntax inferred the parent concept from the name using
uppercase letter heuristics. The new syntax makes the parent
concept explicit and unambiguous.
Added type_system_tests module with comprehensive tests.
Added complete support for the new type system syntax including:
- concept: Base type declarations
- sub_concept: Enum and record sub-type definitions
- concept_comparison: Compile-time pattern matching with conditional guards
Parser changes:
- Added VariantPattern, FieldCondition, and Condition AST nodes
- Implemented "is" keyword for pattern matching (e.g., "CupType is Glass or CupType is Plastic")
- Added Value::Any variant to support universal type matching
- Disambiguated enum-like vs record-like sub_concept syntax
LSP updates:
- Added Value::Any match arms across code_actions, completion, hover, inlay_hints, and semantic_tokens
- Type inference and formatting support for Any values
Example fixes:
- Fixed syntax error in baker-family behaviors (missing closing brace in nested if)
- Removed deprecated core_enums.sb file
