giles	9d3e54029a	js-on-sx: switch/case/default/break ... Parser: jp-parse-switch-stmt + jp-parse-switch-cases + jp-parse-switch-body. AST: (js-switch discr (("case" val body) ("default" nil body) ...)). Transpile: wraps body in (call/cc (fn (__break__) ...)). Each case clause becomes (when (or __matched__ (js-strict-eq discr val)) (set! __matched__ true) body). Fall-through works naturally via __matched__. Default appended as (when (not __matched__) body). 363/365 unit (+6), 148/148 slice unchanged.	2026-04-23 21:04:22 +00:00
giles	6c4001a299	js-on-sx: postfix + prefix ++/-- ... Parser: jp-parse-postfix emits (js-postfix op target) on trailing ++/--; jp-parse-primary emits (js-prefix op target) before the unary -/+/!/~ branch. Transpile: js-transpile-prefix → (set! name (+ (js-to-number name) ±1)) for idents, (js-set-prop obj key ...) for members/indices. js-transpile-postfix caches old value in a let binding, updates, returns the saved value. 340/342 unit (+11), 148/148 slice unchanged.	2026-04-23 20:50:10 +00:00
giles	ce46420c2e	js-on-sx: regex literal lex+parse+transpile+runtime stub ... Lexer: js-regex-context? disambiguates / based on prior token; read-regex handles [...] classes and \ escapes. Emits {:type "regex" :value {:pattern :flags}}. Parser: new primary branch → (js-regex pat flags). Transpile: (js-regex-new pat flags). Runtime: js-regex? predicate, js-regex-new builds tagged dict with source/flags/global/ignoreCase/multiline/sticky/unicode/dotAll/ hasIndices/lastIndex. js-regex-invoke-method dispatches .test/.exec/ .toString. js-invoke-method detects regex receivers. Stub engine uses js-string-index-of; __js_regex_platform__ + override! let a real engine plug in later. Runner: repeatable --filter flags (OR'd). 308/310 unit (+30 regex tests), 148/148 slice unchanged.	2026-04-23 20:27:19 +00:00
giles	9e568ad886	js-on-sx: baseline commit (278/280 unit, 148/148 slice, runner stub) ... Initial commit of the lib/js/ tree and plans/ directory. A previous session left template-string work in progress — 278/280 unit tests pass (2 failing: tpl part-count off-by-one, escaped-backtick ident lookup). test262-runner.py and scoreboard are placeholders (0/8 with 7 timeouts); fixing the runner is the next queue item.	2026-04-23 19:42:16 +00:00
