- README: add performance section (beats gforth 2-10x), update test
commands, note self-recursive direct calls and loop promotion
- CLAUDE.md: update test counts (427 unit + comparison tests)
- OPTIMIZATIONS.md: stack-to-local Phase 1→Phase 2 (loops + IF),
DO/LOOP locals done, J as IR done, add section 14 (self-recursive
direct call), add current performance table vs gforth
- WAFER.md: document self-recursive call optimization, CONSOLIDATE,
update test commands and line counts
- FORTH.md: expanded space history, add FORTH-IN-SPACE.md reference
- FORTH-IN-SPACE.md: new document with verified spacecraft history
All were planning artifacts never imported or loaded:
- forth/ (4 .fth files): commented-out TODO stubs, never loaded at startup
- crates/core/src/words/mod.rs: empty module with commented-out submodules
- compiler.rs: placeholder, all compiler logic lives in outer.rs
- primitives.rs: placeholder, all primitives registered in outer.rs
- types.rs: StackType/StackEffect defined but never imported anywhere
Replace placeholder compliance tests with real harness that boots WAFER,
loads Gerry Jackson's test suite, and asserts 0 errors per word set.
Passing word sets (11/13):
Core, Core Plus, Core Ext, Exception, Double-Number, String,
Search-Order, Memory-Allocation, Programming-Tools, Facility, Locals
Not yet: File-Access (needs WASI), Floating-Point, Extended-Character
272 total tests (261 unit + 11 compliance)
Core word set: 0 errors on Gerry Jackson's forth2012-test-suite/core.fr
- Fix POSTPONE for non-immediate words via COMPILE, mechanism
- Fix double-DOES> (WEIRD: pattern) with does-body scanning and
runtime patching via _DOES_PATCH_
- Implement CATCH/THROW exception handling using wasmtime trap
mechanism with stack pointer save/restore
- 232 tests passing
- Fix HERE corruption: sync user_here before writing to shared cell
- Fix DOES> without CREATE: patch most-recent word, not read new name
- Implement >BODY via word_pfa_map tracking parameter field addresses
- Nested BEGIN...WHILE...WHILE...REPEAT...ELSE...THEN support
- DEPTH overflow protection
- Forth 2012 core.fr: 3 errors remaining (POSTPONE edge case,
double-DOES>, NOP meta-programming)
README now documents all 70+ implemented words, working examples,
architecture overview, and accurate compliance status.
CLAUDE.md updated with actual file descriptions, patterns for adding
new words, and current test count.
Optimizing Forth 2012 compiler targeting WebAssembly with IR-based
compilation pipeline, multi-typed stack inference, subroutine threading,
and JIT/consolidation modes. Rust kernel with ~35 primitives and Forth
standard library for core/core-ext word sets.
