The Logos lexer produces dedicated token variants for all keywords
(Token::Behavior, Token::LifeArc, etc.) — Token::Ident is only for
user-defined identifiers. determine_context() was matching against
Token::Ident(keyword), so last_keyword was always None and every
nested block returned CompletionContext::Unknown, causing
all_keyword_completions() to dump top-level declaration keywords
everywhere.
Changes:
- determine_context(): match actual token variants (Token::Behavior,
Token::LifeArc, Token::Relationship, Token::Character, etc.) and
track last_context directly instead of a String keyword
- behavior_keyword_completions(): add all word-based BT keywords
(choose, then, repeat, if, when, invert, retry, timeout, cooldown,
succeed_always, fail_always)
- InFieldBlock arm: always include field_keyword_completions() so
generic fields (age, bond, etc.) appear even without a species
- Tests: add negative assertions confirming top-level keywords are
absent inside behavior/life_arc blocks; add new test
test_behavior_no_toplevel_keywords for nested block isolation
This commit completes the migration started in the previous commit,
updating all remaining files:
- Lexer: Changed token from Extends to Modifies
- Parser: Updated lalrpop grammar rules and AST field names
- AST: Renamed Schedule.extends field to modifies
- Grammar: Updated tree-sitter grammar.js
- Tree-sitter: Regenerated parser.c and node-types.json
- Examples: Updated baker-family work schedules
- Tests: Updated schedule composition tests and corpus
- Docs: Updated all reference documentation and tutorials
- Validation: Updated error messages and validation logic
- Package: Bumped version to 0.3.1 in all package manifests
All 554 tests pass.
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 tests verifying semantic token highlighting for concept,
sub_concept (enum and record forms), and concept_comparison
declarations. Made token_type_index pub(crate) for test access.
Updated binary format spec for v0.3.0 type system changes:
- Section 3 (Types): concept, sub_concept, concept_comparison encoding
- Section 4 (Characters): Value/Expression discriminant renames
- Section 5 (Templates): species_base field for inheritance
- Section 12 (Life Arcs): required_fields with type annotations
- Section 13 (Enums): note on sub_concept enum distinction
- Changelog and version history updated
Also fixed clippy/import issues in LSP semantic tokens module.
Added top-level keyword completions for:
- concept: with semicolon-terminated snippet
- sub_concept: with dot notation snippet
- concept_comparison: with brace-delimited snippet
Added test verifying type system keywords appear in
completions with correct snippet formatting.
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.
Checks that concept_comparison variant names exist in the referenced
concept's enum sub-concepts and that all variants are covered
(exhaustiveness checking).
ConceptRegistry tracks all concepts and sub_concepts, providing lookup
and validation for sub-concept variant/field references. Supports both
enum and record sub-concept kinds.
When a template extends a species via species_base, shared field names
must have compatible types. Range values are compatible with their
underlying numeric types (Number or Decimal).
When a template has a species_base, its fields are loaded first as the
lowest priority layer. Override order: species -> includes -> template
-> character (last-one-wins for field values).
Added optional species_base field to Template struct enabling
template-species inheritance syntax: `template Name: Species { ... }`.
Updated LALRPOP grammar and all Template construction sites.
Added validation that sub_concept declarations reference an existing
parent concept. Produces clear error message with guidance to add
the missing concept declaration.
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
Added AST structures for new type system:
- ConceptDecl: Base type definition
- SubConceptDecl: Enum or record subtype with SubConceptKind
- ConceptComparisonDecl: Compile-time enum mapping
- ConceptMapping: Individual mapping entry
Added Declaration enum variants and stubs throughout codebase
for LSP, resolve, and semantic analysis modules.
Added four keywords for new type system:
- concept: Base type definition
- sub_concept: Enum/record sub-type definition
- concept_comparison: Compile-time enum mapping
- any: Universal type for dynamic contexts
Also added:
- CLAUDE.md with project instructions and commit guidelines
- Test coverage for new keywords
- Crate-level deny directives for unused variables and dead code
Fixed pre-existing clippy issues to pass pre-commit hooks.
