spec/ now contains only the language definition (5 files): evaluator.sx, parser.sx, primitives.sx, render.sx, special-forms.sx lib/ contains code written IN the language (8 files): stdlib.sx, types.sx, freeze.sx, content.sx, bytecode.sx, compiler.sx, vm.sx, callcc.sx Test files follow source: spec/tests/ for core language tests, lib/tests/ for library tests (continuations, freeze, types, vm). Updated all consumers: - JS/Python/OCaml bootstrappers: added lib/ to source search paths - OCaml bridge: spec_dir for parser/render, lib_dir for compiler/freeze - JS test runner: scans spec/tests/ (always) + lib/tests/ (--full) - OCaml test runner: scans spec/tests/, lib tests via explicit request - Docker dev mounts: added ./lib:/app/lib:ro Tests: 1041 JS standard, 1322 JS full, 1101 OCaml — all pass Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

;; freeze.sx — Serializable state boundaries
|
|
;;
|
|
;; Freeze scopes collect signals registered within them. On freeze,
|
|
;; their current values are serialized to SX. On thaw, values are
|
|
;; restored. Multiple named scopes can coexist independently.
|
|
;;
|
|
;; This is a library built on top of the evaluator's scoped effects
|
|
;; (scope-push!/scope-pop!/context) and signal system. It is NOT
|
|
;; part of the core evaluator — it loads after evaluator.sx.
|
|
;;
|
|
;; Usage:
|
|
;; (freeze-scope "editor"
|
|
;; (let ((doc (signal "hello")))
|
|
;; (freeze-signal "doc" doc)
|
|
;; ...))
|
|
;;
|
|
;; (cek-freeze-scope "editor") → {:name "editor" :signals {:doc "hello"}}
|
|
;; (cek-thaw-scope "editor" frozen-data) → restores signal values
