…hema validation - meta.schema.json now requires 'grammar', 'stages', 'exit' properties - Create test/validate_schemas.py — validates config.json and all meta.json files against their schemas, with clear error messages - Add schema validation step to both CI workflows (ci.yml, tests.yml) before running tests, ensuring invalid meta.json is caught early
Add tokens.schema.json to validate test tokens.json files. Mandatory fields: kind (string), line (integer >=1), column (integer >=1). Optional field: value (string).
The validate_schemas.py script now also loads tokens.schema.json and validates every tokens.json found under test/. The schema requires: - kind (string), line (integer >=1), column (integer >=1) — mandatory - value (string) — optional This runs in CI as part of the 'Validate JSON schemas' step in both ci.yml and tests.yml workflows.
- Create ast.schema.json for AST tree validation: each node requires line, column, kind; allows any other fields (value, elems, body, …). - Update tokens.schema.json: remove 'value' from properties (no longer tracked in schema), remove 'additionalProperties: false' so any token fields are accepted. Only 'kind', 'line', 'column' remain required.
Each AST node now has: - elems: ordered list of child nodes (previously in named fields like body, left, right, cond, then, else, init, etc.) - value: scalar payload (name, op, message, field, type, literal value) or null for nodes without one - Extra fields (mut, type, returnType, etc.) preserved
All ast.json golden files regenerated using the fixed compiler that: - Removes AST_EXPR_STMT wrapper from expression statements - Produces correct elems arrays per documented format (Declare: [name, init], FuncDecl: [name, params..., body], ExternDecl: [name, params...], StructDecl: [name, fields...], Param: [name], FieldAccess: [base, name]) - Reports correct line/column positions (first token of each node) - Drops the value field (not compared during golden validation)
Verify that top-level declarations (extern, def, struct) can appear in any order at the top level: - grammar3: def and extern interleaved - grammar4: def and extern with typed params/return types - grammar5: struct, extern, and def all interleaved
The run_tests.py output format recently changed: - list command now groups tests under === STAGE === headers with indented names (no stage/ prefix) - test/update commands now group results under === STAGE === headers and print names without stage prefix - config stage key is 'compiler' not 'compile' Also fix test_compiler_update_regenerates_and_exit_warning to produce non-empty stdout so the golden file is written. All 54 self-tests now pass.
Adds 5 new self-tests covering recently added features in run_tests.py: - Backward compat: stages=['compiler'] auto-adds 'run' stage - Backward compat: exit dict for 'run' stage falls back to 'compiler' key - run_exec update with empty stdout removes golden and reports message - LLVM stage golden comparison is skipped without --check-ir flag - Fuzz tests in list output use separate FUZZ header with stage/name format All 59 self-tests pass (54 existing + 5 new).
