Implements plans/01-see-introspection.md, all phases.
- see.rs: feature-free IR pretty-printer (format_ir/format_ir_with),
exhaustive over IrOp -- a new variant fails the build, not the output.
- SEE-IR <name>: post-optimization IR view with resolved callee names,
immediate/does> annotations; host-word and interpreter-token stubs.
- SEE <name>: verbatim source capture for colon words (multi-line,
comments preserved, EVALUATE-nesting safe, error-path wiped, MARKER/
REMEMBER/EMPTY roll word sources back too). Data definers (VARIABLE/
CONSTANT/CREATE/BUFFER:/2*/F*/SYNONYM) record synthesized one-liners
at definition time; VALUE/2VALUE/FVALUE/DEFER synthesize at SEE time
so current values and IS targets show. Fallback chain ends at IR dump
or host-word stub -- SEE never dead-ends on a defined word.
- HELP [<name>]: wordhelp.rs doc table with stack effect + one-line
description for EVERY word in a fresh VM (300+ dictionary words plus
all outer-interpreter tokens); a coverage test fails the build if a
word is ever added undocumented. User words echo their leading
( ... -- ... ) comment. SEE/SEE-IR prepend the HELP line as a
\ comment. Bare HELP prints usage.
- boot.fth colon definitions get real sources for free (they flow
through evaluate); INTERPRETER_TOKENS gained the missing ?DO.
524 unit + 11 compliance + 9 comparison + 5 crypto + 1 bench green;
fmt/clippy clean; core still builds --no-default-features; web
wasm-pack build unchanged.
- 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.
