- Sanitize sort names: Option(NodeId) → Option_NodeId
- Emit action transition predicates only for verify/BMC mode
- Handle -> implication operator in translateExpr
- Fleshed out KRaft invariant bodies (4/6 now have real expressions)
- ToggleSwitch: clean sat with model
- TigerBeetleLedger: sat with model
- KafkaKRaft: sat with model
- All 37 tests pass
- x in someSet → someSet.has(x)
- x in someMap.keys → someMap.has(x)
- x notIn someMap.keys → !someMap.has(x)
- m[k] → m.get(k) for Map state variables
- s.size() → s.size (property, not method)
- Track Map-typed state variables via mapVarNames for accurate .get() translation
- Thread mapVarNames through emitAction and rewriteExpr
All 41 tests passing. TigerBeetleLedger now generates correct TypeScript
with .get() for Map access and .has() for Set membership.
Part of M0.1: Fix TS generator bugs (speckl#18)
- Add 'precondition' and 'postcondition' ActionStatement types
- Parse precondition: expr and postcondition: expr in action bodies
- Support 'or' continuation lines for multi-clause pre/postconditions
- TigerBeetleLedger now parses 21 preconditions + 24 postconditions
(previously all dropped, resulting in empty action bodies)
- All 41 existing tests pass
Addresses marcus/engineering#9 (parser gap)
Does NOT wire into generators yet — TypeScript/WASM output
will be empty for pre/postconditions. Generator wiring
is follow-up work.
Undcompiled map/record/unrecognized assignments emitted (i32.const 1)
placeholders that left values on the WASM stack. Combined with
the default return i32.const 1 at end of function, this caused
type mismatch errors (expected [], got [i32, i32] or [i32]).
Fix: make uncompiled assignments emit comment-only output with
no stack effect. Scalar assignments already work correctly since
emitExpr feeds into global.set which consumes the value.
Closes#9 WASM E2E portion — parser fix for precondition:/postcondition:
keyword handling still needed.
- check-dist.sh: Prevents DIST DESYNC by verifying all dist/*.js files
are newer than their src/*.ts sources. Fails build if stale.
- Makefile: Standard build targets (build/check-dist/test/recompile/clean)
- src/index.ts: Integrated dist freshness check before compilation
- src/parser.ts: Added List<T> type parsing alongside existing Set<T>/Map<K,V>
(e.g., 'log: List<LogEntry>' now parses as { type: 'list', elementType })
- examples/: Restored v0.3 state machine specs (TigerBeetleLedger,
AccountLedger, ToggleSwitch, TwoPhaseCommit)
- DIST DESYNC is a known recurring anti-pattern — this guard prevents it
Tests: 39/41 pass (2 pre-existing E2E WASM failures due to missing wabt)
- Add __tests__/e2e-wasm.test.ts: full pipeline test
- Parse Counter speck → generate WAT → assemble with wabt → instantiate → run
- Verify init, action calls, guard pass/fail, state mutations
- TigerBeetle WAT validation test (wabt parse + validate + toBinary)
- Fix wasm.ts bugs found by E2E:
- Guard condition inverted: added i32.eqz to negate comparison
- Missing local declarations: locals now inserted before body
- Uncompiled guards left stack values: now emit comments only (no i32.const 1)
- Install wabt npm package for WAT→WASM assembly in tests
- 41/41 tests passing (39 original + 2 E2E)
Milestone: Speckl produces runnable WebAssembly from specs.
Adds a first-class TypeScript code generator to speckl-compile that emits:
- Const enum for workflow states (IssueWorkflowState)
- Strongly-typed class with guards, state transitions, decision log
- Proper this. prefixing (state vars only, not local params)
- Enum references instead of string literals for state comparisons
- Clean tsc --noEmit compilation
Also includes:
- specs/forgejo-issue-workflow.speckdl — full workflow with 9 actions,
8 constraints, 5 temporal verifications
- Generator deduplication of duplicate AST nodes
- Support for init block initialization of state variables
The generator was validated against the Forgejo issue workflow spec,
producing IssueWorkflow.ts that compiles with zero errors.
Refs: heartbeat conversation re: speckl-compile extensibility
